technical field

The invention relates to the field of communication technology, in particular to a registration method and network equipment.

Background technique

In the IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) network, users need to open an account in the network and register to enjoy the service. During the registration process, the terminal used by the user accesses the IMS network through different border proxy devices, such as the Proxy-Call Session Control Function (P-CSCF, Proxy-Call Session Control Function). Register with the call session control function entity (S-CSCF, Servering-Call Session Control Function) and the application server (AS, Application Server) that provides services to it.

After the registration is completed, in order to keep the user active and the service contract to take effect in a timely manner, it is necessary to continuously interact between the user terminal and the core-side network elements through periodic registration messages to ensure that each core-side network element is aware of the user's status and The user's latest business contract status.

A periodic user registration will generate a large amount of signaling interaction, which needs to be processed by the core network element, which increases the burden on the signaling network and occupies the service processing capacity of the core network element.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in Figure 1, a registration method provided by an embodiment of the present invention includes:

Step 11, receiving a service request message sent by a user terminal (UE, User Equipment);

Wherein, the service request message may be an INVITE request message sent when the terminal initiates a call service. Of course, the service request message here is not limited to the INVITE request message, and may also be other messages such as an instant message MESSAGE initiated by the user terminal.

Step 12, determining that the expires header field is carried in the service request message;

Taking the service request message as an INVITE request message as an example, the terminal carries the expires header field in the call setup INVITE request message. Send the INVITE request message to the network element on the core side. The network element at the core side may directly receive the INVITE request message sent by the terminal, or may indirectly receive the INVITE request message sent by the terminal.

Among them, the expires header field is the header field format defined in the RFC 3261 standard protocol, and an expires header field can be added in the existing INVITE message or MESSAGE message.

Step 13, triggering a registration service according to the expires header field.

After receiving the INVITE request message carrying the header field, the network element at the core side triggers the registration service of the user according to the expires header field.

If the method is applied in the IMS domain, then the network element at the core side may be the serving call session control function entity S-CSCF.

If the method is applied to a traditional Code Division Multiple Access (CDMA, Code Division Multiple Access) network, then the core side network element can be a Mobile Soft Switching Center (MSCe, MobileSwitching Center emulation).

If the method is applied to the traditional Global System for Mobile Communications (GSM, Global System for Mobile Communications) and Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System), then the core side network element can be a Mobile Switching Center (MSC, Mobile Switching Center).

In the registration method provided by this embodiment, the expires header field is carried in the business process, and the registration service is triggered according to the expires header field to refresh the registration time of the terminal, ensure the activation status of the user, and reduce the periodic registration behavior of the user. Therefore, the impact of the periodic registration signaling on the signaling network is reduced, and the burden on the network and the processing burden on the network element at the core side are reduced.

As shown in Figure 2, the embodiment of the present invention provides another registration method, including:

Step 21, receiving the service request message sent by the user terminal;

Step 22, determine that the service request message carries an expires header field, and the expires header field includes the first registration duration.

The first registration duration may be the registration duration of the last successful registration of the terminal, and the registration duration used for successful registration is negotiated during the registration process; it may also be other durations. If the terminal uses other durations, the registration may be invalidated. For example, if the duration is too short, the registration will fail. When the registration fails because the registration time is too short, it will not affect the business initiated by the terminal this time, but in this case, the registration process is not completed in this business process, which is no different from the ordinary business process. Wherein, the first registration duration is preferably the registration duration of the last successful registration of the terminal.

Step 23, triggering a registration service according to the first registration duration carried in the expires header field.

For example, it may refresh the registration time of the terminal (or refresh the activation time of the terminal) according to the first registration duration, and/or update the user subscription data, and may also include other services performed during the registration process. Wherein, the activation time of the terminal is refreshed. For example, when the core side network element receives the INVITE message carrying the expires header field, if the user terminal does not re-register within the first registration period, the user status is changed to the logout status. Updating user subscription data can be through interaction with home subscriber server (HSS, Home Subscriber Server) through server assignment request (SAR, Server Assignment Request)/server assignment response (SAA, Server AssignmentAnswer) to obtain user subscription data, etc. .

In another embodiment of the present invention, the network element at the core side may re-determine a new registration duration according to its own policy and the first registration duration, which is referred to as the second registration duration herein. Then use the second registration duration to trigger the user's registration service. The policy mentioned here can be pre-set on the core side network element according to the operator's policy; it can also be determined by the core side network element according to its own load situation, and of course it is not limited to the above two cases. For example, if the first registration duration is 3600s, but the registration duration required by the operator set on the core side network element is not greater than 3100s, then the core side network element re-determines the first registration duration according to the first registration duration and the registration duration set on it. Second, the registration time is 3100s. After determining that 3100s is the registration duration, a new second registration duration may also be sent to the terminal.

In another embodiment of the present invention, after receiving the service request message carrying the header field, the network element at the core side not only triggers the registration service, but also performs corresponding service processing according to the service request message. For example, if the service request message is an INVITE request message, the service here refers to the call service. If the service request message is an instant message, then the service here refers to an instant message service.

For the process of business failure, the registration process is considered to be a failure. The terminal judges the timing of periodic registration initiation according to the timer set by itself.

In this embodiment, the expires header field is carried in the service process, so that the core side network element triggers the registration service according to the registration duration carried in the header field (for example: refreshing the registration time of the user terminal to ensure the activation status of the user terminal), reducing User's periodic registration behavior. Therefore, the impact of the periodic registration signaling on the signaling network can be reduced, and the burden on the network and the processing burden on the network element at the core side can be reduced. For example, the user registration time is 1 hour, and the service (could be a call service, an instant message service, etc.) is initiated on average once an hour. Taking the call service as an example here, in the prior art, the user needs to initiate two periodic registrations and one call within one hour. However, using the solution provided by this embodiment, the user terminal only needs to initiate one periodic registration and one call. For another example, a user registers for 2 hours and initiates an average call every hour. In the prior art, a periodic registration and a call need to be initiated within one hour. However, using the solution provided in this embodiment, the user terminal only needs to initiate a call once. Therefore, the impact of the periodic registration signaling on the signaling network is reduced, and the burden on the network and the processing burden on the network element at the core side are reduced.

As shown in FIG. 3 , taking the case where a user completes registration during initiating a call service in the IMS as an example, the embodiment of the present invention provides another registration method.

In step 301, a user uses a terminal to initiate an INVITE request message.

Wherein, the terminal carries the expires header field (also called the expired header field) in the INVITE message of call setup according to the previous registration duration, and carries the registration duration in the expires header field. As mentioned here, carrying the registration duration in the expires header field can directly carry the registration duration information; it can also add an indication in expires, for example: the indication duration is the same as the previous registration duration.

The first registration duration may be the last successful registration duration of the terminal, and the successful registration duration has been negotiated during the registration process; it may also be other durations. If the terminal uses other durations, the registration may be invalidated. For example, if the duration is too short, the registration will fail. When the registration fails because the registration time is too short, it will not affect the business initiated by the terminal this time, but in this case, the registration process is not completed in this business process, which is no different from the ordinary business process. Wherein, the first registration duration is recommended to use the registration duration of the last successful registration of the terminal.

The purpose of carrying the expires header field is to complete the periodic registration service of the user according to the duration carried in the header field during service processing.

In step 302, the P-CSCF selects an S-CSCF and forwards the INVITE to the selected S-CSCF.

In step 303, the S-CSCF determines that the INVITE message carries the expires header field, and then determines that the call process needs to trigger a registration service at the same time. Then refresh the user registration time according to the registration time carried in the expires header field. Interact with HSS through SAR/SAA to obtain user subscription data.

In step 304, the S-CSCF determines that the user's service needs to be triggered on AS1 according to the initial filter rules (IFC, Initial Filter Criteria), and then sends an INVITE message carrying the expires header field to AS1.

Step 305, AS1 first processes the called service of the user according to the original process, and at the same time triggers the registration service according to the registration duration carried in the expires header field, for example: to refresh the registration time of the user terminal, AS1 can also request (UDR , User Data Request)/User Data Answer (UDA, User Data Answer) interacts with HSS to obtain user subscription data.

In step 306, AS1 sends the INVITE message to the S-CSCF after completing the user service processing.

Step 307, the S-CSCF calls the called user.

Step 308, S-CSCF finds that the AS registered for the user is not all triggered in this service, and then sends a REGISTER message to the remaining AS (here AS2 is an example. Because AS1 is the AS that handles this call, but AS2 does not need to process call services, so a REGISTER message needs to be sent to trigger AS2 to register) to trigger periodic registration.

In step 309, AS2 interacts with the HSS through UDR/UDA to obtain user subscription data.

Step 310, AS2 returns a registration success response 200 message to the S-CSCF.

Wherein, steps 308, 309 and 310 are optional.

Step 311 , after the called call is connected, the calling side will be notified through a 200 message, and the 200 message will be returned to the calling terminal according to the INVITE message path.

Step 312 , according to the previous registration service processing, the S-CSCF packs the actual registration duration of the user terminal into the 200 message through the expires header field, and sends the 200 message to AS1.

Step 313, AS1 returns the 200 message to the S-CSCF.

In step 314, the S-CSCF sends a 200 message to the P-CSCF.

In step 315, the P-CSCF sends a 200 message to the terminal side. After receiving the 200 message, the terminal user will obtain the expires header field from the 200 message, and know how long it takes for the user to re-register during this call. In this way, the user can initiate periodic registration or services in the next registration period.

Optionally, if the expires header field is not carried in the 200 message, it is considered that the registration also fails. The terminal judges the timing of periodic registration initiation according to the original timer.

In this embodiment, the expires header field is carried in the call service process, so that the S-CSCF can trigger the registration service according to the registration duration carried in the header field (for example, refresh the registration time of the user terminal to ensure the activation state of the user terminal), reducing Periodic registration behavior of user terminals. For example, the user registration time is 1 hour, and an average call is made every hour. In the prior art, the user needs to initiate two periodic registrations and one call within one hour. However, using the solution provided by this embodiment, the user terminal only needs to initiate one periodic registration and one call. Therefore, the impact of the periodic registration signaling on the signaling network is reduced, and the burden on the network and the processing burden on the network element at the core side are reduced.

The embodiment of the present invention provides another registration method. The difference between this registration method and the embodiment shown in FIG. 3 is that in step 302, after receiving the INVITE request message, the S-CSCF determines that the INVITE message carries the expires header field, and then determines that the call process needs to trigger a registration service at the same time. The S-CSCF re-determines a new registration duration (for example, registration duration B) according to its own policy and the registration duration carried in the expires header field (for example, registration duration A). Then use the re-determined registration duration B to trigger the registration service of the user terminal. The strategy mentioned here can be preset on the S-CSCF according to the operator's strategy; it can also be determined by the S-CSCF according to its own load conditions, and of course it is not limited to the above two situations. For example, if the registration duration A is 3600s, but the registration duration required by the operator set on the S-CSCF is not greater than 3100s, then the S-CSCF re-determines the registration duration B to be 3100s according to the registration duration A and the registration duration set on it . After determining that 3100s is the registration duration, in step 315 the registration duration B is sent to the terminal. In this way, the terminal will use the registration duration B to initiate periodic registration or services in the next registration period.

In this embodiment, the expires header field is carried in the call service process, so that the S-CSCF can re-determine a registration duration according to the registration duration carried in the header field and its own policy, and then trigger the registration service according to the re-registration duration (for example, refresh the user terminal registration time to ensure the activation status of the user terminal), reducing the periodic registration behavior of the user terminal. Therefore, the impact of the periodic registration signaling on the signaling network is reduced, and the burden on the network and the processing burden on the network element at the core side are reduced. Moreover, at each registration, the S-CSCF will update the registration duration according to its own policy, and then send the updated registration duration to the terminal. Since the updated registration duration is determined by the S-CSCF according to network conditions or operator policies, etc., it is ensured that the terminal can use the updated reasonable registration duration to initiate registration, for example, it can avoid registration failure caused by too short registration duration question.

As shown in FIG. 4 , the embodiment of the present invention provides another registration method. In the IMS, the user terminal completes registration during the process of initiating an instant message service as an example.

The difference between this embodiment and the embodiment shown in FIG. 3 is that the flow in FIG. 3 is an INVITE message, but in this embodiment it is a MESSAGE message.

Wherein, steps 408, 409 and 410 are optional.

Optionally, if the sending of the instant message fails, it is considered that the registration also fails. The terminal judges the timing of periodic registration initiation according to the original timer. For example, if the expires header field is not carried in the 200 message, the terminal judges the timing of periodic registration initiation according to the original timer.

In this embodiment, the expires header field is carried in the instant message service process, so that the S-CSCF can trigger the registration service according to the registration duration carried in the header field (for example, refreshing the registration time of the user terminal to ensure the activation status of the user terminal), reducing User's periodic registration behavior. For example, the user registration time is 1 hour, and an instant message is sent every hour on average. In the prior art, the user needs to initiate two periodic registrations and one instant message within one hour. However, using the solution provided by this embodiment, the user terminal only needs to initiate one periodic registration and one instant message. Therefore, the impact of the periodic registration signaling on the signaling network is reduced, and the burden on the network and the processing burden on the network element at the core side are reduced.

The embodiment of the present invention provides another registration method. This registration method is different from the embodiment shown in FIG. 4 in that, in step 402, after receiving the MESSAGE message, the S-CSCF judges that the MESSAGE message carries the expires header field, and then determines that the instant message process needs to process the registration service at the same time. The S-CSCF re-determines a new registration duration (for example, registration duration B1) according to its own policy and the registration duration carried in the expires header field (for example, registration duration A1). Then use the re-determined registration duration B1 to trigger the user's registration service. The strategy mentioned here can be preset on the S-CSCF according to the operator's strategy; it can also be determined by the S-CSCF according to its own load conditions, and of course it is not limited to the above two situations. For example, if the registration duration A1 is 3600s, but the registration duration required by the operator set on the S-CSCF is not greater than 3100s, then the S-CSCF re-determines the registration duration B to be 3100s according to the registration duration A1 and the registration duration set on it . After determining that 3100s is the registration duration, in step 314 the registration duration B1 is sent to the terminal. In this way, the terminal will use the registration duration B1 to initiate periodic registration or services in the next registration period.

In this embodiment, the expires header field is carried in the process of sending the instant message, so that the S-CSCF can re-determine a registration duration according to the registration duration carried in the header field and its own policy, and then trigger the registration service according to the re-registration duration (for example : Refresh the registration time of the user terminal to ensure the activation state of the user terminal), reducing the periodic registration behavior of the user terminal. Therefore, the impact of the periodic registration signaling on the signaling network is reduced, and the burden on the network and the processing burden on the network element at the core side are reduced. Moreover, at each registration, the S-CSCF will update the registration duration according to its own policy, and then send the updated registration duration to the terminal. Since the updated registration duration is determined by the S-CSCF according to network conditions or operator policies, etc., it is ensured that the terminal can use the updated reasonable registration duration to initiate registration, for example, it can avoid registration failure caused by too short registration duration question.

In the network device provided in this embodiment, the expires header field is carried in the service process, so that the network device triggers the registration service according to the expires header field, so as to refresh the registration time of the terminal, ensure the activation status of the user, and reduce the cycle time of the user Sexual Registration Act. Therefore, the impact of the periodic registration signaling on the signaling network is reduced, and the burden on the network and the processing burden on the network element at the core side are reduced.

Optionally, the expires header field includes the first registration duration. The first registration duration may be the registration duration of the terminal's last successful registration, and the registration duration used for successful registration is negotiated during the registration process; it may also be other durations. If the terminal uses other durations, the registration may be invalidated. For example, if the duration is too short, the registration will fail. When the registration fails because the registration time is too short, it will not affect the business initiated by the terminal this time, but in this case, the registration process is not completed in this business process, which is no different from the ordinary business process. Wherein, the first registration duration is recommended to use the registration duration of the last successful registration of the terminal.
