In order to improve the response speed of the HSS in the IMS network, an embodiment of the present invention provides that a cache may be created in the HSS in advance, response data obtained from the database is placed in the cache when the user equipment first initiates a user request, and relevant response data in the cache is directly returned when the user equipment subsequently initiates the same user request again, without operating the local database to determine the relevant response data.

Accordingly, as shown in fig. 1, an embodiment of the present invention provides a data processing method applied to an HSS, where the method includes the following steps:

in step S11, when it is determined that the currently received data acquisition request is not received for the first time, acquiring response data corresponding to the data acquisition request from a cache created in advance; the data acquisition request is sent to the HSS by the network equipment according to a user request sent by the user equipment;

in step S12, the response data is returned to the network device, so that the network device processes the user request according to the response data.

The user request may be sent to the current network device by the user equipment, or sent to other network devices by the user equipment, and only the other network devices request the current network device to perform further processing. The HSS includes at least a pre-provisioned cache and database.

After the user equipment sends a user request, the current network equipment sends a corresponding data acquisition request to the HSS to acquire user information related to the user equipment, the HSS can judge whether the data acquisition request is received for the first time, because the data acquisition request is sent to the HSS by the network equipment according to the user request sent by the user equipment, the data acquisition request is judged whether the user request is initiated by the user equipment for the first time or not, if the user equipment is initiated not for the first time, response data corresponding to the data acquisition request is acquired from a cache opened in advance so as to be returned to the network equipment, and the network equipment can process the user request.

It should be noted that after the user equipment sends the user request, the network equipment sometimes sends other types of requests to the HSS in addition to sending a corresponding data acquisition request to the HSS, which is not related to the embodiments of the present invention and therefore is not described in detail.

It can be seen from the foregoing steps S11-S12 that, after the user equipment sends the user request, the network equipment sends a corresponding data acquisition request to the HSS, and the HSS determines whether the data acquisition request is received non-first time, and when it is determined that the data acquisition request is received non-first time, because the HSS creates a cache in advance and response data corresponding to the data acquisition request is stored in the cache, the HSS can directly acquire the response data corresponding to the data acquisition request from the cache created in advance, and return the response data to the network equipment, so that the network equipment processes the user request according to the response data, thereby avoiding determining related response data by operating a local database, for example, performing operations such as query, modification, and deletion on data in the database, reducing a processing load of the HSS, increasing smoothness of responding to the user request, and improving a speed of responding to the user request.

If the currently received data acquisition request is determined to be received for the first time, it is indicated that the user request of this time is initiated by the user equipment for the first time, the relevant response data is not stored in the cache, and the HSS still needs to determine the relevant response data.

Accordingly, in some embodiments, as shown in fig. 2, before the returning the response data to the network device (i.e., step S12), the method may further include the following steps:

in step S10', when it is determined that the currently received data acquisition request is received for the first time, determining response data corresponding to the data acquisition request;

in step S11', the determined response data is stored in the pre-opened buffer.

In some embodiments, the step of storing the determined response data in the pre-opened cache (i.e. step S11') may include the steps of: and under the condition that the state code carried in the determined response data meets a preset condition, storing the determined response data into the pre-opened cache.

As a specific implementation manner, the determining that the status code carried in the response data satisfies the preset condition may include: and the value of the state code carried in the determined response data is less than 400. For example, httpStatusCode <400.

If the value of the status code carried in the response data is greater than or equal to 400, it indicates that the data acquisition request is in error, and if the value of the status code carried in the response data is less than 400, it indicates that at least the data acquisition request is successful. That is, if the value of the status code carried in the response data is greater than or equal to 400, the response data only serves to notify the network device that the request is in error, and at this time, the response data does not carry the user information, and it is meaningless to store the response data.

With the increase of the number of users in the IMS network and the development of platform services, the amount of data stored in the HSS is increasing, and in order to further reduce the processing load of the HSS and increase the response speed, the HSS may also create a plurality of caches in advance, each of which is used to store response data corresponding to a different data acquisition request.

Accordingly, in some embodiments, the cache is opened from the memory according to the YML configuration file, the number of the caches is multiple, as shown in fig. 3, and the step of obtaining the response data corresponding to the data obtaining request from the cache opened in advance (i.e., the step S11) may include the following steps:

in step S111, determining a cache corresponding to the data acquisition request;

in step S112, the response data is acquired from the cache corresponding to the data acquisition request.

Wherein, some important parameters are recorded in the YML configuration file, and the HSS can set a cache basic function, a port and the like in advance according to the parameters in the YML configuration file, and open a section of space from the local storage as a cache. The cache opened up in advance by the HSS may include a plurality of caches each for storing different types of response data. When a data acquisition request is received, determining which cache stores response data corresponding to the data acquisition request, and then acquiring the response data from the determined cache.

For different data acquisition requests, different APIs (application program interfaces) are often required to be called so as to execute different instructions to acquire corresponding response data.

Accordingly, in some embodiments, different data fetch requests call different local APIs, as shown in fig. 4, and after tunneling the cache, the method may further include the steps of:

in step S21, a storage key is created for each cache;

in step S22, a one-to-one correspondence between the parameter information of the API and the cache is generated;

in step S23, the determining the cache corresponding to the data obtaining request includes: and determining the cache corresponding to the data acquisition request according to the local API called by the data acquisition request and the corresponding relation.

After setting a cache basic function, a port and the like in advance according to parameters in a YML configuration file and creating a section of space from a local storage as a cache, the HSS can also respectively create different storage keys for each cache in a program, bind a certain API and the storage key of a certain cache, generate a unique ID or value of the binding relationship, and store the corresponding relationship among the storage keys, the ID or value and the API parameters in the cache for the subsequent identification and reading of cache contents by the program.

In some embodiments, after receiving the data acquisition request, the method may further include the steps of: creating a client structure; analyzing the data acquisition request to acquire request parameters; storing the request parameters to a parameter list of the client structure; extracting command parameters from a parameter list of the client structure; and determining the local API called by the data acquisition request according to a command protocol and the command parameters.

When a socket (socket) corresponding to the monitoring port receives a connection request, a client structure is created, and the connection state is managed through the client structure. When a request enters, the request is read, buffered and analyzed, and then stored into a parameter list of the client. And then finding a corresponding Command according to the parameter list of the client, and finally further analyzing, verifying and executing the Command according to the Command protocol. The core processing thread for data reading and writing is a single thread model, and in order to keep the high performance of the whole system, the blocked operation caused by any thread must be avoided.

After the data acquisition request is parsed, the client structure may also be deleted to release the memory. Accordingly, in some embodiments, after the response data is obtained from the cache corresponding to the data obtaining request, the method may further include the following steps: and deleting the client structure.

As mentioned above, the HSS may pre-open a plurality of buffers for storing different types of response data. Accordingly, in some embodiments, the step of storing the determined response data in the pre-opened cache (i.e. step S11') may include the steps of: and storing the determined response data into a corresponding cache according to the local API called by the data acquisition request and the corresponding relation.

The HSS has more functions in the IMS network, which may include registration, authentication, deregistration, location query, and so on, and accordingly, in some embodiments, the user request is any one of a registration request, an authentication request, a location query request, and a deregistration request.

It should be noted that the embodiments of the present invention are not limited to the above-listed requests, and any request that needs to obtain the user information from the database of the HSS may be within the scope of the embodiments of the present invention.

The I-CSCF and S-CSCF are two network devices that often need to obtain user information to the HSS in order to handle user requests. Accordingly, in some embodiments, the network device may include at least a call session control function entity, I-CSCF, and a serving session control function entity, S-CSCF.

It should be noted that the embodiments of the present invention are not limited to the two network devices listed above, and any network device that needs to obtain the user information from the database of the HSS to process the user request may be within the scope of the embodiments of the present invention.

The principle of the data processing method provided by the embodiment of the present invention is briefly described below with reference to fig. 5.

As shown in fig. 5, which is a schematic diagram of a principle of a data processing method provided in an embodiment of the present invention, after a client (i.e., a user equipment) initiates a request, an HSS determines whether the request is sent by the client for the first time, substantially determines whether corresponding response data exists in a cache, if the corresponding response data exists in the cache, responds to the request of the client according to the cached data, and if the corresponding response data does not exist in the cache, starts a MySQL (relational database management system) function, performs operations such as query, modification, and deletion on data in a database, responds to the request of the client according to an operation result, and adds the response data to the cache.

The data processing method provided by the embodiment of the invention is described in detail below with reference to fig. 6 and a specific embodiment.

Taking the registration process of the User Equipment in the IMS Network as an example, the Visited Network includes the User Equipment (UE) and a P-CSCF, and the Home Network includes an I-CSCF, an HSS and an S-CSCF, as shown in fig. 6, the registration process may include the following steps (1) - (20).

Step (1), UE sends Register request message to P-CSCF of visiting network, starts the registration process for the first time. The Register request message includes a user identifier, a home network domain name, user information, session description information, and the like.

And (2) the P-CSCF processes the Register request message, uses the domain name of the home network in the Register request message to query the DNS to obtain an I-CSCF entry point in the home network, and forwards the Register request message to the I-CSCF.

Step (3), the I-CSCF sends a User Authorization Request (UAR) to the HSS, and after the HSS authenticates the identity and the service authority of the user equipment, the HSS indicates the I-CSCF because the UAR is judged to be sent for the first time: one S-CSCF is allocated to serve the UE according to the required S-CSCF capabilities and the available S-CSCFs. Meanwhile, the HSS determines the information of IMSU, IMPU, IMPI and the like, and respectively stores the information in corresponding caches, and the cache module of the HSS returns a ResultCode (2001) message to the HSS.

Wherein, at least before step (3), the HSS has previously opened up a cache.

And (4) the HSS sends UAA (user authorization response) to the I-CSCF, and the UAA carries the capability set corresponding to the IMSU.

And (5) after the I-CSCF adds the capability set corresponding to the IMSU in the Register request message, the I-CSCF forwards the Register request message to the allocated S-CSCF.

And (6) the S-CSCF sends a Multimedia Authentication Request (MAR) to the HSS, the MAR carries information such as an authentication scheme, the SIP authentication item number and the like, the HSS acquires IMPI from a pre-opened cache and assembles an authentication vector according to the acquired IMPI and the information carried by the MAR as the MAR is judged to be sent for the first time, the user state of the IMPU is set to be pending for authentication, then the IMPU in the cache is updated, the names of the S-CSCF in the database and the cache are updated, and a cache module of the HSS returns a ResultCode (2001) message to the HSS.

And (7) the HSS sends an MAA (multimedia authentication answer) to the S-CSCF, wherein the MAA carries authentication information.

Step (8) the S-CSCF returns a 401 (unauthorised) message to the I-CSCF.

Step (9), I-CSCF returns 401 (unauthorized) message to P-CSCF.

Step (10), P-CSCF returns 401 (unauthorized) message to UE.

Wherein a 401 (unauthorized) message is used to inform the UE to re-authenticate.

And step (11), the UE restarts the registration process by the Register request message sent to the P-CSCF of the visited network. The Register request message includes authentication information, a user identifier, a home network domain name, user information, session description information, and the like.

And (12) the P-CSCF processes the Register request message, uses the domain name of the home network in the Register request message to query the DNS to obtain an I-CSCF entry point in the home network, and forwards the Register request message to the I-CSCF.

And (13) the I-CSCF sends a User Authorization Request (UAR) to the HSS for the second time, and the HSS directly reads the IMSU in the cache to obtain the name of the S-CSCF because the UAR is judged to be not sent for the first time, and the cache module of the HSS returns a ResultCode (2002) message to the HSS.

And (14) the HSS sends the UAA carrying the authentication information to the I-CSCF, wherein the authentication information at least comprises the name of the S-CSCF allocated to the UE by the I-CSCF.

And step (15), the I-CSCF forwards the Register message to the designated S-CSCF according to the name of the S-CSCF returned by the UAA.

And step (16), the S-CSCF sends a Service Allocation Request (SAR) to the HSS after the authentication is passed, and the HSS sets the user state of the IMPU as the registered IMPU which is updated in the cache.

And (17) the S-CSCF downloads SAA (service allocation answer) from HSS, wherein the SAA carries the relevant information of the UE, such as subscription information, safety information and the like.

And (18) the S-CSCF completes Service Control and returns a 200 OK message (registration confirmation information) to the I-CSCF.

Step (19), I-CSCF returns 200 OK message (registration confirmation information) to P-CSCF.

And step (20), the P-CSCF returns a 200 OK message (registration confirmation information) to the UE, and the registration process is completed.
