Detailed ways

The technical scheme of the present invention can be applied to various communication systems, such as: GSM (GlobalSystem of Mobile communication, Global System for Mobile Communications), CDMA (Code Division Multiple Access, Code Division Multiple Access) system, WCDMA (Wideband Code Division Multiple Access Wireless, Broadband Code Division Multiple Access), UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System), GPRS (General Packet Radio Service, General Packet Radio Service), LTE (Long Term Evolution, long-term evolution), etc.

UE, also called mobile terminal (Mobile Terminal), mobile user equipment, etc., can communicate with one or more core networks through the radio access network (for example, RAN, Radio Access Network) through the air interface, and the user equipment can be Mobile terminals, such as mobile telephones (or "cellular" telephones) and computers with mobile terminals, such as portable, pocket, hand-held, built-in computer, or vehicle-mounted mobile devices, that communicate with the radio access network language and/or data.

A base station is a network element of the above wireless access network, which can be a BTS (Base Transceiver Station, base station) in GSM or CDMA, or a base station (NodeB) in WCDMA, or an evolved base station ( eNB or e-NodeB, evolved Node B), etc., the present invention is not limited.

Fig. 1 is a schematic diagram of a mobile network system applicable to an embodiment of the present invention. The schematic diagram of the mobile network system in FIG. 1 includes an access network and a core network, wherein the access network includes a base station and a controller.

It should be understood that in the embodiment of the present invention, although three base stations are described in FIG. 1 , namely base station 101, base station 102 and base station 103; one controller 104 and core network 105, this is only for convenience of description. The number of each network device in FIG. 1 may be one or more, which is not limited in this embodiment of the present invention.

In the prior art, in order to reduce the pressure of downlink data traffic on the transmission network, content storage nodes are deployed to each base station. For example, in the schematic diagram of the scene in Figure 1, base station 101, base station 102 or base station 103 can store mobile Internet content, In this way, the UE can obtain mobile Internet content nearby, which can save the backhaul from the base station to the core network, and from the core network to the Internet, and shorten the waiting delay time of the terminal.

However, the content storage capacity of a single base station is limited and the maintenance cost is relatively high, so it is not possible to deploy a large number of storage units in each base station. The probability that the Internet content requested to be accessed is stored in the base station 101 is small, and the Internet content requested to be accessed has diversity, which will lead to a low hit rate of access to the content stored in a single base station. Therefore, the base station still needs to pass through the controller, core network Going to the Internet network to obtain the Internet content requested by the UE to the UE does not effectively save the backhaul from the base station to the core network, and from the core network to the Internet, and shorten the waiting delay time of the terminal.

In order to solve the above problems, an embodiment of the present invention provides a method and device for storing Internet content, which enables multiple base stations to share their respective stored Internet content, increases the access hit rate of the Internet content stored by the base station, and improves storage utilization. Thereby effectively saving transmission overhead and reducing delay time.

Fig. 2 is a flow chart of an Internet content storage method according to an embodiment of the present invention. The method in FIG. 2 is executed by the first base station.

201. The first base station sends a first access request message to the second base station when the Internet content requested by the first user equipment to be accessed is stored in the second base station, and the first access request message is used to request the second base station to send the first user equipment The Internet content that the device requests to access is different between the first base station and the second base station.

202. The first base station receives Internet content that is requested to be accessed by the first user equipment and sent by the second base station according to the first access request message.

Wherein, the base station to which the serving cell of the first user equipment belongs is the first base station, and the first base station serving the first user equipment sends an Internet content access request message to the first base station, and the Internet content requested by the first user equipment is provided by the first sent by the base station to the first user equipment. Wherein, the base station to which the serving cell of the first user equipment belongs may be referred to as the serving base station of the first user equipment. The serving base station of a certain user equipment refers to the base station responsible for the radio resource control (RRC, Radio Resource Control) connection between the user equipment and the network side. Under the serving base station, there is at least one cell. The cell covered by the serving base station for the user equipment is called a serving cell. Internet content refers to files obtained by the second base station from the Internet. Optionally, Internet content includes but not limited to video, audio, webpage multimedia or text files, which is not limited in this embodiment of the present invention.

In the embodiment of the present invention, when the Internet content requested by the first user equipment is stored in the second base station, the first base station obtains the Internet content requested by the first user equipment from the second base station and sends it to the first user equipment. The first base station is different from the second base station in that multiple base stations share the Internet content stored separately. Since the storage capacity of multiple base stations is larger than that of a single base station, the access hit rate of Internet content stored in the base station can be increased, and the utilization rate of storage can be improved, thereby effectively saving transmission overhead and reducing delay time.

Optionally, as an embodiment, before step 201, the first base station may determine whether the Internet content requested by the first user equipment is stored in a base station in a set of base stations, the set of base stations includes at least two base stations, including The first base station and the second base station. The second base station refers to a base station other than the first base station in the base station set. Any two base stations in the base station set can be connected through a router or a switch. Optionally, the function of a router or switch between two base stations can be implemented by a third base station.

It should be understood that the embodiment of the present invention does not limit the connection method between the base stations, and it should also be understood that the two interacting base stations are not limited to adjacent geographical locations, and the same base station may be included in different base station sets.

It should be pointed out that the communication between the base stations may adopt an IP (Internet Protocol, Internet Protocol) protocol. A set of base stations can form a mesh network, specifically including: any two base stations in the set of base stations can interact with each other, and each base station in the set of base stations has the same function of storing Internet content. It should be understood that, the embodiment of the present invention does not limit the format of the message exchanged between the base stations or between the base station and the user equipment, and the interface form adopted when exchanging messages between the base stations.

Optionally, in an implementation manner, the first base station stores a content directory table, and the content directory table records the identifiers of Internet content (including the Internet content requested by the first user equipment) stored by the second base station (such as Internet content name) and storage address. Wherein, the content directory table is used by the base station to locate the storage location of the Internet content requested by the user equipment, including for querying whether the Internet content requested by the first user equipment is stored in a certain base station of the base station set and in which base station. . Internet content identifiers are used to uniquely identify Internet content. Specifically, the storage address in the content directory table is used to determine in which base station the Internet content requested by the first user equipment is stored, and the storage address may include the identifier of the second base station and the IP (Internet Protocol, Internet Protocol) address of the second base station at least one of the others.

It should also be noted that usually the resources (Internet content) in the Internet can be described by URL (UniformResource Locator, Uniform Resource Locator). For the convenience of storage and search in the base station, the URL can be mapped to The one-dimensional sequence ID is used as the identifier of the cache resource. Therefore, the content directory table may consist of multiple entries, and each entry may consist of an Internet content identifier (such as a serial ID of a cache resource) and an address actually storing Internet content (such as an IP address of a base station). When the base station obtains the resource (URL) requested by the user equipment, it maps to the sequence ID according to the hash algorithm, and then finds the location of the entry in the content directory table, so as to know the specific storage location.

For example, the second base station sends the identifier of the Internet content stored by the second base station to the first base station. Preferably, the second base station may broadcast the identifier of the Internet content stored by the second base station to other base stations in the base station set, and the other base stations will The identifiers and storage addresses of the Internet content stored by the second base station are recorded and stored in respective content directory tables. The first base station may use the content directory table to determine in which base station the Internet content requested by the first user equipment is stored. For example, the first base station may locate the Internet content requested by the first user equipment to be stored in the second base station through an identification (or an index function referred to as a content table of contents). Optionally, the content directory table stored by the first base station also records the identifier and storage address of the Internet content stored by the first base station.

Preferably, after the first base station receives the message requesting to access Internet content sent by the first user equipment, the first base station determines the storage address of the Internet content requested by the first user equipment according to the stored content directory table, and first determines whether there is a storage address of the Internet content requested by the first user equipment. In the local base station (first base station), if it is not stored in the local base station, it is determined whether to store in other base stations (such as the second base station) of the base station set. When it is determined according to the content directory table that the Internet content requested by the first user equipment is stored in the second base station, the Internet content requested by the first user equipment is obtained from the second base station and sent to the first user equipment.

It should be noted that the content directory table stored by the first base station may be a partial content directory table, which records the identifiers and corresponding storage addresses of Internet content stored by some base stations (including the second base station) in the base station set; The content directory table may also be a global content directory table, which records the identification and corresponding storage address of the Internet content stored by each base station in the base station set. The recording form of the content directory table is not limited in the embodiment of the present invention, and the content directory table is used by the base station to locate the storage location of the Internet content that the user equipment requests to access.

Optionally, in another implementation manner, the first base station may send a query request message to the control server, where the query request is used for the control server to query the Internet content that the first user equipment requests to access from the content directory table stored in the control server. storage address. In the embodiment of the present invention, the control server can be logical, and the function of the control server can be implemented by a certain base station, or it can be deployed in other devices except the base station. Of course, the control server can also be an independent device , which is not limited in this embodiment of the present invention.

For example, the first base station sends the query request to the control server when the local base station does not store the Internet content that the first user equipment requests to access. When the control server receives the query request message sent by the first base station, it can locate the first user device according to the content directory table stored in the control server through the information (such as the identifier) of the Internet content requested by the first user device in the query request message The storage location of the Internet content requested to be accessed. When the Internet content requested by the first user equipment queried from the content directory table is stored in the second base station, the control server sends a query response message to the first base station, and the query response message carries the queried first user equipment request. Information on accessed Internet content is stored in the second base station. After receiving the query response message, the first base station may determine that the Internet content requested by the first user equipment is stored in the second base station. Wherein, the content directory table stored by the control server includes identifiers and storage addresses of Internet content stored by the second base station.

It should be noted that the content directory table stored by the control server may be a partial content directory table, which records the identifiers and corresponding storage addresses of Internet content stored by some base stations in the base station set (including the second base station in the base station set). The control server may be shared by multiple base stations in the base station set, that is to say, other base stations in the base station set may also execute the embodiment of the first base station, and accordingly, the content directory table stored by the control server may be a global content directory table , which records the identifier and corresponding storage address of the Internet content stored by each base station in the base station set. The recording form of the content directory table is not limited in the embodiment of the present invention. The content directory table stored by the control server is used by the control server to locate the storage location of the Internet content requested by the user equipment according to the query request message sent by the base station.

Optionally, the control server may send an unqueried query response message to the first base station or no action.

Through the above scheme, when the base station of the serving cell requests for the first user equipment of the first base station to access Internet content, when the requested Internet content is stored in other base stations in the base station set, the first base station can locate the storage of the requested Internet content location, so that the storage space of other base stations can be utilized, the utilization rate of storage can be improved, and the access hit rate of the Internet content stored in the base station can be increased, and there is no need to obtain from the Internet network the first user equipment that is not stored in the local base station to request access to the Internet content. Thereby effectively saving transmission overhead and reducing delay time.

Optionally, as another embodiment, the first base station may update the Internet content stored in the local base station, and may store that the first user equipment under the local base station requests a large number of visits (the number of visits is greater than a certain number threshold, which may be determined by the first The base station makes statistics, and the second base station can also make statistics) Internet content (also referred to as "hot content"), here, the number of times the Internet content requested by the first user equipment to be accessed may be the number of times the Internet content is accessed by the first user equipment The total number of times that all user equipments served by the base station request the Internet content.

Specifically, when a certain Internet content (such as Internet content W) is accessed more than a certain threshold within a statistical period, the Internet content W can be migrated from the second base station to the first base station, that is, from the second base station Delete and store in the first base station, at this time, the storage information of the corresponding Internet content W can be updated. There are various specific migration procedures. For example: Optionally, before storing the Internet content requested by the first user equipment, when the first base station receives a migration request message sent by the second base station, the migration request message is used to indicate that the first The base station stores the Internet content requested by the first user equipment; or, the first base station receives a move-in request message sent by the control server, where the move-in request message is used to instruct the first base station to store the Internet content requested by the first user equipment.

For example, within the statistical period, the second base station counts the number of requests initiated by the first base station to access the Internet content W, and when within the statistical period, the second base station detects the counted number of requests initiated by the first base station to access the Internet content W (i.e. When the number of access request messages sent by the first base station to access Internet content W) is greater than a certain number threshold, the second base station may send a relocation request message to the first base station, and after receiving the relocation request message sent by the second base station, the first base station will The Internet content W is stored in the local base station, and the second base station can delete the stored Internet content W.

Of course, the first base station may also count the number of requests for accessing Internet content W initiated by user equipment under the first base station. When the number of requests for W is greater than a certain number threshold, the first base station may send a relocation request message to the second base station, and store the Internet content W in the local base station. After receiving the relocation request message sent by the first base station, the second base station deletes the stored Internet content W.

For another example, within the statistical period, the control server counts the number of query request messages sent by the first base station to query the storage address of the Internet content W; When the number of address query request messages is greater than a certain threshold, the control server may send an Internet content W move-out request message to the second base station and send an Internet content W move-in request message to the first base station. Correspondingly, the control server changes the storage address of the Internet content W from "identification of the first base station" to "identification of the second base station". When the first base station receives the migration request message of the Internet content W sent by the control server, the first base station stores the Internet content W. When the second base station receives the move-out request message of the Internet content W sent by the control server, the second base station deletes the stored Internet content W.

For another example, the first base station may store the Internet content that is requested by the first user equipment for access times greater than the number threshold and that is not stored in other base stations in the base station set. Further, after the first base station updates the interconnection content stored in the local base station, it may broadcast to other base stations in the base station set. Optionally, in the case where the control server stores the content directory table, after the first base station updates the Internet content stored in the local base station, it may notify the control server, specifically, the first base station may update the locally stored Internet content The identification and storage address of the first base station (such as the identification of the first base station or the IP address of the first base station) are sent to the control server, so that the control server updates the content directory table.

It should be noted that after a certain base station in the base station set updates the interconnection content stored in the local base station, it may notify other base stations in the base station set in the form of broadcast. Optionally, when the control server stores the content directory table, after a certain base station in the base station set updates the interconnection content stored in the local base station, it can notify the control server, so that the control server can update the content directory table.

Therefore, updating the stored Internet content through the base station can improve the flexibility of storage. The Internet content stored by the base station is requested by the user equipment under the base station for a large number of visits, effectively reducing the access overhead between base stations and reducing the delay. .

It should be understood that the above examples are only illustrative, and no matter what the reason is, the update of the stored Internet content by the base station should fall within the scope of the present invention.

Optionally, as another embodiment, the first base station may also play the role of the second base station. Specifically, the first base station may receive a second access request message sent by the second base station, and the second access request message is used to request the second access request message. A base station sends the Internet content requested to be accessed by the second user equipment, and the first base station sends the Internet content requested to be accessed by the second user equipment to the second base station according to the second access request message. The Internet content requested to be accessed by the second user equipment is stored in the first base station, and the base station to which the serving cell of the second user equipment belongs is the second base station. The second base station sends the received Internet content requested to be accessed by the second user equipment sent by the first base station to the second user equipment.

In addition, when the Internet content requested by the first user equipment is stored in the first base station, the first base station obtains the Internet content requested by the first user equipment from the first base station and sends it to the first user equipment. Specifically, it may be determined whether the Internet content requested by the first user equipment to be accessed is stored in the first base station through the content directory table stored in the first base station. For example, when the content directory table stored in the first base station records When the identifier of the accessed Internet content and the corresponding storage address include the identifier of the first base station, it is determined that the Internet content requested by the first user equipment to be accessed is stored in the first base station.

Or, in the case that the Internet content requested by the first user equipment is not stored in any base station of the at least two base stations (i.e., a set of base stations), the first base station retrieves the content from the original Internet network (i.e., via the core network and the controller) ) acquiring the Internet content requested by the first user equipment and sending it to the first user equipment. Specifically, it may be determined through the content directory table stored by the first base station whether any base station in the base station set stores the Internet content that the first user equipment requests to access, for example, when the global content directory table stored by the first base station does not contain When recording the identifier of the Internet content that the first user equipment requests to access, it may be determined that the Internet content that the first user equipment requests to access is not stored in any base station in the base station set.

Preferably, the first base station first determines whether the Internet content requested to be accessed is stored in the local base station after receiving the message requesting to access the Internet content sent by the first user equipment. If it is stored in the local base station, directly obtain the Internet content requested by the first user equipment and send it to the first user equipment; if it is not stored in the local base station, then determine whether it is stored in other base stations of the base station set (such as the second base station) middle. If it is determined to be stored in the second base station, obtain the Internet content requested by the first user equipment from the second base station and send it to the first user equipment; if it is not stored in any base station of the base station set, then from the original The Internet content requested to be accessed by the first user equipment is acquired in the Internet network and sent to the first user equipment. The manner of how to locate the storage address of the Internet content requested to be accessed by the first user equipment is as described above, and will not be repeated here.

Fig. 3 is a flowchart of a method for storing Internet content according to another embodiment of the present invention. The method in FIG. 3 is executed by the second base station, and corresponds to the method in FIG. 2 , so descriptions repeated with the embodiment in FIG. 2 will be appropriately omitted.

301. The second base station receives a first access request message sent by the first base station when the Internet content requested by the first user equipment is stored in the second base station, and the first access request message is used to request the second base station to send the first user equipment The Internet content that the device requests to access is different between the first base station and the second base station.

302. The second base station obtains the Internet content requested to be accessed by the first user equipment according to the first access request message and sends it to the first base station.

Optionally, the Internet content refers to files obtained by the second base station from the Internet, including but not limited to files such as video, audio, webpage multimedia, or text, which is not limited in this embodiment of the present invention.

In the embodiment of the present invention, the second base station receives the access request message sent by the first base station, obtains the Internet content requested by the first user equipment stored in the second base station, and sends it to the first base station. The first base station is different from the second base station, so that the second base station A base station can use the storage space of the second base station to realize that multiple base stations share the Internet content stored separately. Since the storage capacity of multiple base stations is larger than that of a single base station, the access hit rate of Internet content stored in the base station can be increased, and the utilization rate of storage can be improved, thereby effectively saving transmission overhead and reducing delay time.

Optionally, as an embodiment, before step 301, the second base station may send the identifier of the Internet content stored by the second base station to the first base station. Preferably, the second base station can broadcast the identifier of the Internet content stored by the second base station to other base stations in the base station set (including the above-mentioned first base station), and other base stations record the identifier and storage address of the Internet content stored by the second base station in the and stored in their respective content directory tables. Since the content directory table stored by the first base station records the identifier and storage address of the Internet content stored by the second base station, the first base station can use the identifier (or the index function called the content directory table) to locate the Internet that the first user equipment requests to access The content is stored in the second base station.

Optionally, as another embodiment, before step 301, the second base station may send the identifier of the Internet content stored by the second base station to the control server. The control server records and stores the identifier and storage address of the Internet content stored by the second base station in the content directory table. When the first base station sends a query request message to the control server, the control server can store the Internet content requested to be accessed by the first user equipment queried from the content directory table in the second base station, and store the Internet content requested to be accessed by the queried first user equipment The information of Internet content stored in the second base station is sent to the first base station.

It should be noted that the content directory table stored by the control server may be a partial content directory table, which records the identifiers and corresponding storage addresses of Internet content stored by some base stations in the base station set (including the second base station in the base station set). The control server may be shared by multiple base stations in the base station set, that is to say, other base stations in the base station set may also execute the implementation of the second base station, and accordingly, the content directory table stored by the control server may be a global content directory table , which records the identifier and corresponding storage address of the Internet content stored by each base station in the base station set. The recording form of the content directory table is not limited in the embodiment of the present invention. The content directory table is used to control the server to locate the storage location of the Internet content requested by the first user equipment according to the query request message sent by the base station.

Through the above solution, the second base station sends the identifier of the Internet content stored by the second base station to the first base station or the control server, and when the base station of the serving cell requests access to the Internet content for the first user equipment of the first base station, the requested Internet When the content is stored in the second base station, the first base station can locate the storage location of the Internet content requested to be accessed, so that the storage space of the second base station can be utilized to improve storage utilization and increase the access hit rate of the Internet content stored in the base station without requiring The first user equipment requesting access to Internet content that is not stored in the local base station is obtained from the Internet network, thereby effectively saving transmission costs and reducing delay time.

Optionally, as another embodiment, the second base station may update the Internet content stored in the local base station, and may store the Internet content (also known as Internet content) that the first user equipment under the local base station requests to access more times (the number of visits is greater than a certain threshold). It is called "hot content"), and can also "move out" Internet content requested by other base stations (such as the first base station) to access more times, that is, the second base station deletes Internet content requested by other base stations to access more times, and other base stations to store. Here, the number of times the Internet content requested to be accessed by the first user equipment may be the sum of the number of times the Internet content is requested by all user equipments served by the first base station.

For example, when a certain Internet content (such as Internet content W) is accessed more than a certain threshold within a statistical period, the Internet content W can be migrated from the second base station to the first base station, that is, deleted from the second base station And stored in the first base station, at this time, the stored information of the corresponding Internet content W can be updated. There may be various specific migration processes. For example: within the statistical period, the second base station counts the number of requests for accessing Internet content W initiated by the first base station. When the number of requests for initiating access to Internet content W (that is, the number of times the first base station sends an access request message to access Internet content W) is greater than a certain number threshold, the second base station can send a relocation request message to the first base station, and the first base station receives the first base station. After the migration request message sent by the second base station, the Internet content W is stored in the local base station, and the second base station can delete the stored Internet content W.

Further, after the second base station updates the interconnection content stored in the local base station, it may broadcast to other base stations in the base station set. Optionally, in the case where the control server stores the content directory table, after the second base station updates the Internet content stored in the local base station, it may notify the control server, specifically, the second base station may update the locally stored Internet content The identification and storage address of the second base station (such as the identification of the second base station or the IP address of the second base station) are sent to the control server, or the second base station can send Internet content to the control server to change the storage address from the second base station to that of the first base station Indicates a message for the control server to update the content directory table.

Optionally, before the second base station deletes the Internet content that the first user equipment requests to access from the first base station, the second base station receives a move-out request message sent by the control server, where the move-out request message is used to instruct the second base station to delete Internet content requested by the first user equipment to be stored by the second base station. For details, reference may be made to the embodiment in FIG. 2 , which will not be repeated here.

It should be noted that after a certain base station in the base station set updates the interconnection content stored in the local base station, it may notify other base stations in the base station set in the form of broadcast. Optionally, when the control server stores the content directory table, after a certain base station in the base station set updates the interconnection content stored in the local base station, it can notify the control server, so that the control server can update the content directory table.

Therefore, updating the stored Internet content through the base station can improve the flexibility of storage. The Internet content stored by the base station is requested by the user equipment under the base station for a large number of visits, effectively reducing the access overhead between base stations and reducing the delay. .

Of course, the second base station may also play the role of the first base station. For specific implementation manners, reference may be made to the foregoing embodiments, and details are not repeated here.

Fig. 4 is a flowchart of a method for storing Internet content according to another embodiment of the present invention. The method in FIG. 4 is executed by the control server and corresponds to the methods in FIG. 2 and FIG. 3 , so descriptions repeated with the embodiments in FIG. 2 and FIG. 3 will be appropriately omitted.

401. The control server receives a query request message sent by the first base station, where the query request message is used to request the control server to query the storage address of the Internet content that the first user equipment requests to access from the content directory table stored in the control server.

402. The control server queries the storage address of the Internet content requested to be accessed by the first user equipment from the content directory table stored in the control server according to the query request message.

403. The control server sends a query response message to the first base station, where the query response message carries the information that the control server queries that the Internet content requested by the first user equipment is stored in the second base station, so that the first base station can determine the first base station according to the query response message. The Internet content requested by the user equipment to be accessed is stored in the second base station, and the first base station is different from the second base station.

Optionally, the Internet content is a file obtained by the second base station from the Internet, and the Internet content includes but not limited to video, audio, webpage multimedia or text files, which is not limited in this embodiment of the present invention.

In the embodiment of the present invention, the control server can be logical, and the function of the control server can be implemented by a certain base station, or it can be deployed in other devices except the base station. Of course, the control server can also be an independent device , which is not limited in this embodiment of the present invention.

In this embodiment of the present invention, the control server receives the query request message sent by the first base station and queries the storage address of the Internet content that the first user equipment requests to access from the content directory table stored in the control server, and sends the queried address of the Internet content that the first user equipment requests to access. The information that the Internet content is stored in the second base station is sent to the first base station, so that the first base station determines that the Internet content requested by the first user equipment is stored in the second base station, and the first base station is different from the second base station. Therefore, multiple base stations share the Internet content stored separately through the control server. Since the storage capacity of multiple base stations is larger than that of a single base station, the access hit rate of Internet content stored in the base station can be increased, and the utilization rate of storage can be improved, thereby effectively saving transmission overhead and reducing delay time.

Optionally, as an embodiment, before step 401, the control server may receive the identifier of the Internet content stored in the second base station sent by the second base station, and the control server may record the identifier and storage address of the Internet content stored in the second base station in table of contents.

It should be noted that the content directory table stored by the control server may be a partial content directory table, which records the identifiers and corresponding storage addresses of Internet content stored by some base stations in the base station set (including the second base station in the base station set). The control server may be shared by multiple base stations in the base station set, that is to say, other base stations in the base station set may also implement the implementation manner of the first base station (or the second base station). The directory table stored by the control server may be a global content directory table, which records the identifier and corresponding storage address of the Internet content stored by each base station in the base station set. The recording form of the content directory table is not limited in the embodiment of the present invention. The content directory table is used to control the server to locate the storage location of the Internet content requested by the first user equipment according to the query request message sent by the base station.

Optionally, the control server may send an unqueried query response message to the first base station or no action.

Through the above solution, the control server can locate the storage location of the Internet content requested to be accessed, so that multiple base stations can share their respective stored Internet content, improve the storage utilization rate, and increase the access hit rate of the Internet content stored by the base station without obtaining from the Internet network Only the first user equipment that is not stored in the local base station requests to access Internet content, thereby effectively saving transmission overhead and reducing delay time.

Optionally, as another embodiment, the control server can update the stored content directory table. Optionally, after a certain base station in the base station set updates the interconnection content stored in the local base station, it notifies the control server, and the control server updates accordingly. table of contents.

For example, when a certain Internet content (such as Internet content W) is accessed more than a certain threshold within a statistical period, the Internet content W can be migrated from the second base station to the first base station, that is, deleted from the second base station And stored in the first base station, at this time, the storage information of the corresponding Internet content W can be updated to the control server. There are many specific migration procedures. For example, when the second base station detects that the counted number of requests from the first base station to access Internet content W is greater than a certain threshold within the statistical period, the second base station sends a migration request to the first base station. Request message, the second base station "moves out" the Internet content W to be stored by the first base station, and sends an instruction message to the control server to change the storage address of the Internet content W from the second base station to the first base station, when the control server receives the instruction message , change the storage address of the Internet content W from "identification of the first base station" to "identification of the second base station". Alternatively, the control server may make a unified decision on the migration of the stored Internet content between base stations.

Optionally, when the control server detects that the counted number of query request messages sent by the first base station is greater than the number threshold within the statistical period, the control server sends a move-in request message to the first base station and sends a move-out request message to the second base station , and the control server updates the content directory table stored in the control server, wherein the move-in request message is used to instruct the first base station to store the Internet content that the first user equipment requests to access, and the move-out request message is used to instruct the second base station to delete Internet content requested by the first user equipment to be stored by the second base station.

For example, within the statistical period, the control server counts the number of query request messages sent by the first base station to query the storage address of the Internet content W; When the number of query request messages is greater than a certain number threshold, the control server may send a move-out request message of Internet content W to the second base station and send a move-in request message of Internet content W to the first base station. Correspondingly, the control server changes the storage address of the Internet content W from "identification of the first base station" to "identification of the second base station". When the first base station receives the migration request message of the Internet content W sent by the control server, the first base station stores the Internet content W. When the second base station receives the move-out request message of the Internet content W sent by the control server, the second base station deletes the stored Internet content W.

Therefore, by controlling the server to update the stored content directory table, the base station updates the stored Internet content accordingly, which can improve the flexibility of storage. The Internet content stored by the base station is requested by the user equipment under the base station. Effectively reduce access overhead between base stations and reduce time delay.

Embodiments of the present invention will be described in detail below with reference to the embodiments shown in FIGS. 5-8 .

Fig. 5 is a schematic structural diagram of a set of base stations according to an embodiment of the present invention. Two base station sets are depicted in FIG. 5 . Base station set 1 includes 5 base stations, respectively, base stations A1, B1, C1, D1, and E1; base station set 2 includes 5 base stations, respectively, base stations C1, B2, C2, and D2. and E2, any two base stations in each base station set can be connected through routers or switches. It should be understood that the embodiment of the present invention does not limit the number of multiple base stations included in the base station set and the method of connection between the base stations. It should also be understood that the two base stations interacting are not limited to adjacent geographic locations. A base station may be included in different base station sets, such as base station C1. A set of base stations can form a mesh network, which specifically includes: any two base stations in the set of base stations can interact with each other, and each base station in the set of base stations has the same function of storing Internet content.

Optionally, each base station in each base station set stores Internet content, and correspondingly stores a content directory table, which records the identifier and corresponding storage address of the Internet content stored by each base station in the base station set. Preferably, different base stations store different Internet contents. In this way, the storage utilization rate of the base station can be improved. Alternatively, each base station set stores the content directory table in a control server (such as the control server S1 of base station set 1 or the control server S2 of base station set 2). Multiple base stations can share their respective stored Internet content.

It should be understood that the control server can be logical, and the function of the control server can be realized by a certain base station, or it can be deployed in other equipment except the base station. Of course, the control server can also be an independent device. The implementation of the present invention Examples are not limited to this.

It should also be understood that some base stations in the base station set may not store Internet content but only a content directory table, which is not limited in this embodiment of the present invention.

The implementation of the present invention will be described in detail below by taking base station set 1 in FIG. 5 as an example. As shown in FIG. 6 , the base stations of the serving cells of UE601 and UE602 are base station A1 , and the base station of the serving cell of UE603 is base station D1 .

Step 1, UE601 initiates a request to base station A1 to access Internet content W. Optionally, the base station A1 knows from the content directory table currently stored in the base station A1 that the Internet content W requested by the UE 601 is not stored in any base station of the base station set 1, and obtains the Internet content W from the Internet network 604 and sends it to the UE 601. Alternatively, when base station A1 determines that the Internet content W requested by UE601 is not stored in base station A1, it sends a query request message to control server S1, and base station A1 learns from the query response message sent by control server S1 that the control server does not query the content W. The Internet content W is stored in other base stations of the base station set 1, and the Internet content W is obtained from the Internet network 604 and sent to the UE601.

Step 2, the base station A1 stores the Internet content W obtained from the Internet network 604 . Optionally, broadcast to other base stations (base stations B1, C1, D1, and E1) in base station set 1, and other base stations can record the Internet content identifier W and the identifier A1 of the storage address base station A1 in their respective content directory tables and store them or, the base station A1 notifies the control server S1, and the control server S1 records and stores the Internet content identifier W and the identifier A1 of the storage address base station A1 in the content directory table.

Step 3, UE602 initiates a request to base station A1 to access Internet content W. Since the base station A1 has stored the Internet content W, the base station A1 sends the stored Internet content W to the UE602. Therefore, the base station A1 does not need to obtain Internet content from the Internet network to send to the UE 602, thereby saving transmission overhead and reducing delay time.

or

UE603 initiates a request to base station D1 to access Internet content W. Optionally, the base station D1 determines from the content directory table stored in the base station D1 that the Internet content W is stored in the base station A1; or, when the base station D1 sends a query request message to the control server S1 when the local base station does not store Internet content, The control server S1 can locate the Internet content W stored in the base station A1 according to the content directory table stored by the control server S1 through the identifier of the Internet content requested by the UE603 in the query request message, and return a query response message to the base station D1, the query response message Carrying the queried identifier of the base station A1, the base station D1 determines that the Internet content W is stored in the base station A1 according to the query corresponding message. Base station D1 sends an access request message to base station A1, and the request message may carry the identifier W of the Internet content that UE603 requests to access. Base station A1 sends Internet content W to base station D1, and base station D1 returns it to UE603.

Through the above solution, when the base station of the serving cell requests access to Internet content for the user equipment of the first base station, when the requested Internet content is stored in other base stations in the base station set, the first base station can locate the storage location of the requested Internet content, In this way, the storage space of other base stations can be utilized to improve the utilization rate of storage, increase the access hit rate of Internet content stored in the base station, and do not need to obtain from the Internet network the user equipment that is not stored in the local base station to request access to Internet content, thereby effectively saving Transmission overhead and reduced latency.

Fig. 7 is a schematic structural diagram of Internet content updated and stored by a base station according to an embodiment of the present invention. The base stations of the serving cells of UE701 and UE702 are base station D1, the base station of the serving cell of UE703 is base station A1, and the Internet content W is stored in base station A1.

UE701 and UE702 under base station D1 initiate a request to base station D1 to access Internet content W, and base station D1 obtains Internet content W from base station A1 and sends it to UE701 and UE702. The specific implementation process can refer to the above, and will not be repeated here. That is to say, UE701 and UE702 need to access and obtain Internet content W through the transmission between base station D1 and base station A1. While the UE703 under the base station A1 initiates a request to access the Internet content W, the base station A1 can directly send the Internet content W stored in the local base station to the UE703. When the base station A1 detects that the number of accesses to the Internet content W initiated by the base station D1 is greater than the number of visits to the Internet content W initiated by the local UE of the base station A1, the base station A1 may send a migration request of the Internet content W to the base station D1. After receiving the migration request of the Internet content W sent by the base station A1, the base station D1 stores the Internet content W, and the base station A1 can delete the locally stored Internet content W.

Optionally, base station A1 broadcasts to other base stations in base station set 1 after updating their respective stored Internet content, and other base stations can correspondingly update the stored content directory table, and delete the record of Internet content W stored in base station A1. Similarly, base station D1 also broadcasts to other base stations in base station set 1 after updating their respective stored Internet content, and other base stations can correspondingly update the stored content directory table and add Internet content W to the record stored in base station D1. Alternatively, base station A1 and base station D2 both notify the control server S1 after updating their respective stored Internet content, and the control server S1 updates the content directory table, and changes the record of Internet content W stored in base station A1 to Internet content W stored in base station D1. Alternatively, the control server S1 may make a unified decision to migrate the stored Internet content between base stations.

The processor 1402 may also be configured to record the identifier and storage address of the Internet content stored by the second base station received by the receiver 1401 in the content directory table.

Further, the processor 1402 may also be configured to update the content directory table stored in the memory 1404 . Specifically, when a certain Internet content (such as Internet content W) is accessed more than a certain threshold within a statistical period, the Internet content W can be migrated from the second base station to the first base station, that is, from the second base station Delete and store in the first base station, and correspondingly, the processor 1402 is configured to update the storage information of the Internet content W in the content directory table stored in the memory 1404 .

Optionally, the processor 1402 is specifically configured to: update the content directory table stored in the control server when the control server detects that the counted number of query request messages sent by the first base station is greater than a threshold value within the statistical period. The transmitter 1403 may also be configured to: send a move-in request message to the first base station and send a move-out request message to the second base station. Wherein, the move-in request message is used to instruct the first base station to store the Internet content requested by the first user equipment, and the move-out request message is used to instruct the second base station to delete the Internet content stored by the second base station and requested to be accessed by the first user equipment.

It should be noted that the content directory table stored by the control server may be a partial content directory table, which records the identifiers and corresponding storage addresses of Internet content stored by some base stations in the base station set (including the second base station in the base station set). The control server may be shared by multiple base stations in the base station set, that is to say, other base stations in the base station set may also implement the implementation manner of the first base station (or the second base station). The directory table stored by the control server may also be a global content directory table, which records the identifier and corresponding storage address of the Internet content stored by each base station in the base station set.
