Description

A method and device for communication using white spectrum

technical field

The present invention relates to the field of communication technologies, and in particular, to a method and device for utilizing white spectrum communication.

Background technique

The rapid growth of the number of mobile terminals has brought great challenges to the existing mobile communication bandwidth. Among them, the shortage of bandwidth resources has prompted the demand for more spectrum resources, and the emergence of white spectrum utilization technology can greatly alleviate the shortage of wireless bandwidth resources.

For the application of the white spectrum technology, the method of querying the database (Database) is generally adopted at present. A database is used to centrally manage the white spectrum resources within a region.

The basic model of the white spectrum application system is shown in Figure 1. In this system, the white spectrum device refers to the device that uses the white spectrum to provide wireless access services for other devices. The white spectrum device can be a base station, AP (Access Point, access point), etc.; the white spectrum database maintains a certain area available white spectrum information. The white spectrum device uses the PAWS (Protocolto Access White Space, white spectrum database access protocol) protocol to request the white spectrum database for available white spectrum information in its geographical location, and then uses the requested white spectrum information to provide other devices (such as UE) with Wireless access service.

An existing implementation solution is to configure an available white spectrum database in a white spectrum device. For example, the address information of the white spectrum database available for the device may be configured in the firmware of the device by the device manufacturer when the device leaves the factory. However, the biggest disadvantage of this configuration is poor flexibility. For example, for a white spectrum device used in China, the available white spectrum database can be configured in this way when the device is used in China, but when the device roams to another country, it needs to be re-registered The device is configured with the available white spectrum databases, and the user of the white spectrum device may not know which white spectrum databases are available in the country.

In order to avoid the defects of the above technology, another existing implementation scheme is: using a dynamic discovery mechanism to realize the discovery of the white spectrum database by the white spectrum device, that is, when the white spectrum database needs to be used, the white spectrum device will be ) and other information to dynamically obtain the available white spectrum data address. However, this implementation still has some drawbacks. This is because the form of using the geographic location coordinates to identify the geographic location may have the defect of insufficient precision, which will cause the white spectrum device to receive less relevant white spectrum database information. For example, if the white spectrum equipment is used on the border, the country information where the white spectrum equipment is located may be incorrectly determined according to the geographic location coordinate information of the equipment.

It can be seen that, in the prior art, in the process of establishing a connection between the white spectrum device and the white spectrum database, there is still a problem of wrong connection.

Detailed ways

In order for those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above objects, features, and advantages of the embodiments of the present invention more clearly understood, the following describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings. for further details.

For many application scenarios of wireless communication, such as: cellular network, wireless local area network, broadband access, etc., white spectrum can be used to increase wireless bandwidth. Spectrum management agencies allocate a large amount of spectrum resources to wireless applications such as television signal propagation. However, the allocated spectrum resources may not be used for a certain period of time within a certain area. Spectrum that is not used for a certain period of time within a region is called "white spectrum". This situation will result in waste of spectrum resources, therefore, the white spectrum can be reasonably reused.

In order to improve the accuracy of establishing the connection between the white spectrum equipment and the white spectrum database, in the first method embodiment of the present invention utilizing the white spectrum communication, as shown in Figure 2, the specific communication process is as follows:

Step 201: The white spectrum device sends request information for requesting access to the white spectrum database to the server, where the server is used for storing attribute information of the white spectrum database.

For the application of white spectrum technology, the method of querying the database is generally adopted at present. Through the white spectrum database, centralized management of white spectrum resources within a region is carried out.

The attribute information recorded in the white spectrum database may include information such as the geographic range of the spectrum that can be used by the white spectrum device, the usage time period, and the like. When a terminal device needs to use the white spectrum resources, the terminal initiates a white spectrum use request through the white spectrum device in the area to which it belongs, that is, the request information for requesting access to the white spectrum database, and the request information can carry the geographical location of the terminal device, white spectrum Spectrum usage time, required bandwidth, transmission distance, etc.

Step 202, the white spectrum device receives the feedback information returned by the server, the feedback information carries the address information in the attribute information of at least one white spectrum database, and the service provider used to identify the at least one white spectrum database the first identification information.

In this step, the server that has received the request information returns feedback information to the white spectrum device that initiated the request, and the feedback information is based on the LoST (Location to Service Translation Protocol) that is followed between the existing white spectrum device and the server. ) protocol to feed back the address information of the White Spectrum database to the White Spectrum device.

In the existing technology for discovering the white spectrum database by using the dynamic discovery mechanism, the information exchange between the white spectrum device and the server that provides the attribute information of the white spectrum data block adopts the LoST protocol. The LoST protocol is a service discovery protocol of a client-server model. The protocol includes two entities: a LoST client (client) and a LoST server (server). In the embodiment of the present invention, the white spectrum device serves as the LoST client. The LoST client provides its geographic location information (Locationinfo) and the service type information to be used (service identifier) to the LoST server, and the LoST server finds out the location that can provide the required service according to the geographic location information and service type information provided by the LoST client. The address information of a series of servers, the provided addresses can be in the form of URLs (Uniform ResourceLocator, Uniform Resource Locator), and these URLs are returned to the LoST client; these addresses represent the addresses of the servers where the White Spectrum database is located; LoST After the client receives these URLs, it can find the server that can provide white spectrum database services for it. For example: in emergency services (such as 110 calls), when a user requests an emergency service, what they want to get is the address of the service center that can provide emergency services for their location, and the LoST server will be based on the geographic location information provided by the user and The service type information returns the address of the server that can provide services for the user. The geographic location information that can be used in the LoST protocol includes two forms of geographic coordinates, city streets and house numbers.

The white spectrum database allocates available white spectrum resources to the terminal device through a corresponding algorithm according to the information provided by the terminal device and the white spectrum information stored by the terminal device.

It should be noted that, in this embodiment of the present invention, in the feedback information sent by the server to the white spectrum device, in addition to carrying the address information in the attribute information of the white spectrum database, more importantly, it carries the information used to identify the white spectrum device. The first identification information of the service provider of the spectrum database. Through the first identification information, attribute information of the service provider of the white spectrum database is provided. Therefore, it is convenient for the white spectrum device receiving the feedback information to directly determine the white spectrum database that can be connected according to the first identification information.

In this embodiment of the present invention, the first identification information is used to identify the service provider of the white spectrum database, and different white spectrum databases may be provided by the same service provider. Therefore, each white spectrum database corresponds to a piece of first identification information, and The same first identification information may correspond to multiple white spectrum databases at the same time.

In the prior art, the URL list of the white spectrum database returned by the LoST server to the LoST client only includes the URL information corresponding to the white spectrum database, which not only includes the URL of the database matching the white spectrum device, but also includes Therefore, when the white spectrum device discovers the white spectrum database according to the URL list, it will cause the white spectrum device to be unable to judge which database corresponding to the URL is suitable for connection. In the implementation mode, the white spectrum device will have to try to establish an attempted connection with each white spectrum database in the returned URL list. It can be seen that the efficiency of selecting a matching white spectrum database is very low.

In the embodiment of the present invention, the feedback information sent by the server to the white spectrum device carries the first identification information used to identify the service provider of the white spectrum database, for example, the administrator information of the white spectrum database is identified by the first identification information. , therefore, when the white spectrum device receives the URL list of the white spectrum database, it can easily determine whether the white spectrum database corresponding to a certain URL matches itself through the first identification information, and then the white spectrum device can directly choose to match connected to the white spectrum database.

Step 203: The white spectrum device establishes a connection with a matching white spectrum database according to the address information and the first identification information, and acquires corresponding white spectrum resources.

In this step, the white spectrum device receives the feedback information returned by the server, because in addition to the address information of the white spectrum database, the feedback information also carries the first identification information for identifying the service provider of the white spectrum database, therefore, The white spectrum device can select a matching white spectrum database from the received address information of the white spectrum database according to the first identification information, thereby establishing a connection with the matching white spectrum database to obtain corresponding white spectrum resources.

Step 204: The white spectrum device provides an access service for a terminal by using the white spectrum resource.

In this step, the white spectrum device acquires the corresponding white spectrum resources from the matched white spectrum database, and then uses these white spectrum resources to provide access services for the terminal.

In this embodiment of the present invention, after the server receives the request information sent by the white spectrum device for requesting access to the white spectrum database, when returning feedback information to the white spectrum device, the feedback information carries the information used to identify the white spectrum database. The first identification information of the service provider, the white spectrum device can obtain the matching white spectrum database information according to the first identification information, so as to directly connect with the matching white spectrum database. Since the white spectrum database to which the white spectrum device initiates the connection matches, the matched white spectrum database can be successfully connected, and then the white spectrum resource can be successfully obtained. It can be seen that the white spectrum device determines the matching white spectrum database through the first identification information, which can greatly improve the accuracy of establishing the connection between the white spectrum device and the white spectrum database.

In the above-mentioned embodiment, for the white spectrum equipment, whether the white spectrum database is available will be affected by the factor of whether the white spectrum equipment that initiates the request has a contractual relationship with the manager of the white spectrum database, and only the white spectrum database with the contractual relationship exists. to successfully establish a connection.

Since the first identification information carried in the feedback information identifies the information of the service provider of the white spectrum database, the white spectrum device can determine whether there is a contract in the white spectrum database corresponding to the first identification information according to the first identification information relation. However, it is not enough to determine whether the current white spectrum database is a matching white spectrum database only by determining whether there is a contractual relationship. There may be multiple white spectrum databases with a contract relationship, and further, it is necessary to determine whether these white spectrum databases with a contract relationship have the white spectrum resources required by the white spectrum device. That is, at least one white spectrum database in which the white spectrum resource required by the white spectrum device exists in the at least one white spectrum database that has a contractual relationship with the white spectrum device is determined as a matching white spectrum database. Finally, the white spectrum device establishes a connection with one of the matched white spectrum databases.

It should be noted that the white spectrum device can select any matching white spectrum database for connection. When the connection between the white spectrum device and the currently selected white spectrum database is successful, the white spectrum device can select another white spectrum database to initiate the connection again.

In the specific implementation process, the "administrator" attribute can be added to the feedback URL list returned by the server, and the information of the service provider of the white spectrum database can be clearly identified by this attribute, for example, the administrator information of the white spectrum database.

In the second embodiment of the method for utilizing white spectrum communication provided by the present invention, as shown in FIG. 3 , the specific communication process is as follows:

Step 301, the server receives the request information sent by the white spectrum device for requesting access to the white spectrum database, and the server is used to store the attribute information of the white spectrum database;

Step 302, the server returns feedback information to the white spectrum device, the feedback information carries the address information in the attribute information of at least one white spectrum database, and the address information used to identify the service provider of the at least one white spectrum database. first identification information; wherein, the first identification information is used for the white spectrum device to determine at least one matching white spectrum database; the address information is used for the white spectrum device and one of the matching white spectrum databases A connection is established, corresponding white spectrum resources are acquired, and access services are provided for terminals by using the white spectrum resources.

This embodiment corresponds to the first embodiment, and describes the communication flow from the server side. After the server receives the request information sent by the white spectrum device for requesting access to the white spectrum database, when returning feedback information to the white spectrum device, the feedback information carries the first ID used to identify the service provider of the white spectrum database. identification information, the white spectrum device can obtain the matching white spectrum database information according to the first identification information, so as to directly connect with the matching white spectrum database. Since the white spectrum database to which the white spectrum device initiates the connection matches, the matched white spectrum database can be successfully connected, and then the white spectrum resource can be successfully obtained. It can be seen that the white spectrum device determines the matching white spectrum database through the first identification information, which can greatly improve the accuracy of establishing the connection between the white spectrum device and the white spectrum database.

The present invention also provides a third embodiment of a method for using white spectrum communication, which can also improve the accuracy of establishing a connection between a white spectrum device and a white spectrum database.

Referring to FIG. 4 , the communication flow in this embodiment includes the following steps:

Step 401, the white spectrum device sends request information requesting access to the white spectrum database to the server, the server is used to store the attribute information of the white spectrum database, and the request information carries the second identification information for identifying the matching white spectrum database. .

In this step, the white spectrum device sends request information requesting access to the white spectrum database to the server. In order to facilitate the establishment of a connection between the white spectrum device and the corresponding white spectrum database, the white spectrum device carries the request information for identifying the matching white spectrum database in the sent request information. the second identification information. Through the second identification information, the white spectrum device clearly identifies the white spectrum database that matches itself.

Since the request information carries the second identification information, the server can, according to the second identification information, clearly know the information of the white spectrum database matching the white spectrum device that initiates the request.

Step 402, the white spectrum device receives the feedback information returned by the server, and the feedback information carries the address information of at least one white spectrum database that matches the white spectrum device determined by the server according to the second identification information. .

In this step, the white spectrum device receives the feedback information returned by the server, and the feedback information carries the address information in the attribute information of the white spectrum database. It should be emphasized that the white spectrum database corresponding to the address information carried in the feedback information matches the white spectrum device that initiated the request. This is because, after receiving the request information carrying the second identification information, the server can directly determine the white spectrum database that matches the white spectrum device according to the second identification information, so that the address information of the matched white spectrum database can be Feedback to the white spectrum device that initiates the request, so that the white spectrum device can directly connect with the white spectrum database.

Step 403: The white spectrum device establishes a connection with one of the matching white spectrum databases according to the address information, and acquires corresponding white spectrum resources.

In this step, since the address information carried in the feedback information corresponds to the white spectrum database matched with the white spectrum device, the white spectrum device can successfully connect with the matching white spectrum database according to the address information.

Specifically, there may be multiple white spectrum databases matching the white spectrum device at the same time. In this case, the white spectrum device establishes a connection with one of the matched white spectrum databases. The white spectrum device can select any matching white spectrum database to connect. When the connection between the white spectrum device and the currently selected white spectrum database is successful, the white spectrum device can select another white spectrum database to initiate the connection again.

Step 404, the white spectrum device provides an access service for the terminal by using the white spectrum resource.

In this step, the white spectrum device acquires the corresponding white spectrum resources from the matched white spectrum database, and then uses these white spectrum resources to provide access services for the terminal.

In this embodiment of the present invention, when the white spectrum device sends request information for requesting access to the white spectrum database to the server, the request information carries second identification information for identifying the matching white spectrum database, and the server, according to the second identification information, The information of the white spectrum database matched with the white spectrum device is fed back to the white spectrum device, so that the white spectrum device can be directly connected with the matched white spectrum database. It can be seen that by carrying the attribute information of the white spectrum database in the interaction information between the white spectrum device and the server, the accuracy of establishing the connection between the white spectrum device and the white spectrum database can be improved.

Similar to the first embodiment, in the embodiment of the present invention, whether the white spectrum database matches is also affected by the factor of whether the white spectrum device that initiates the request has a contractual relationship with the manager of the white spectrum database. In addition, only the white spectrum database that has the white spectrum resources required by the white spectrum device is the matching white spectrum database, so that the connection with the white spectrum device can be successfully established.

It should be noted that, in the specific implementation process, the second identification information carried in the request information may include: service provider information of the matched white spectrum database, or country code information of the country to which the white spectrum device belongs.

One application scenario is that in the request information sent by the white spectrum device to the server, in addition to carrying the geographic location information and service type information of the white spectrum device, a new attribute is added, and the new attribute is used to identify the white spectrum device. Acceptable service provider information of the white spectrum database, for example: if the white spectrum device has a contract with some white spectrum database managers, then the white spectrum device can manage the white spectrum database that has a contract with itself. The information of the user is notified to the server, and when the server receives the identification information that identifies these matching White Spectrum database manager information, it can return only the white spectrum equipment that has a contractual relationship with the White Spectrum equipment according to the identified contract relationship. The address of the spectrum database. Therefore, unnecessary connection between the white spectrum equipment and the white spectrum database without contractual relationship is omitted, and the connection efficiency between the white spectrum equipment and the white spectrum database is greatly improved.

Another application scenario is that in the prior art, the LoST server returns the URL of the server that can provide the corresponding service to the LoST client according to the Location information. However, the geographic location coordinates usually used for the Location information have inherent defects of insufficient precision. When the LoST server returns a server that can provide services according to the Location information, it may return some irrelevant servers to the LoST client. For example, if the white spectrum device is used on the border, when the white spectrum device reports the geographic location coordinate information to the LoST server, the LoST server may incorrectly determine the country where the white spectrum device is located. Aiming at the problem that the LoST server returns too much inappropriate white spectrum database information due to insufficient accuracy of the location information in the form of geographic coordinates, the embodiments of the present invention provide the following corresponding solutions.

Since the white spectrum database maintains the white spectrum information within a country, in order to prevent the server from erroneously judging the country where the white spectrum device is located, in this embodiment of the present invention, the request information for accessing the white spectrum database initiated by the white spectrum information is included in the request information. An attribute element representing country code information is added, and this attribute element is used to clearly identify the country where the white spectrum equipment is currently located.

Therefore, the server feeds back the address information of the white spectrum database corresponding to the country code to the white spectrum device according to the country code information, which can greatly improve the connection efficiency between the white spectrum device and the white spectrum database.
