Problems solved by technology

[0005] Since the logout time of UE is generally long, especially for fixed UE, it will not log out unless it is powered off or manually restarted, and there are a large number of UEs in the network, which will cause P-CSCF2 to be overloaded for a long time. Security risks

Embodiment 1

[0053] Such as figure 2 As shown, a registration control method provided by an embodiment of the present invention includes:

[0054] 201: Detect whether the P-CSCF recovers from the failure.

[0055] Wherein, the registration control method provided by the embodiment of the present invention can be applied in the IMS, and specifically can be applied in a scenario where one or more P-CSCFs in the IMS recover from failure. The execution subject of this embodiment of the present invention may be the SBC.

[0056] The embodiment of the present invention does not limit the specific implementation method of step 201. Optionally, it includes: the SBC sends a heartbeat detection message to the P-CSCF; In response to the message, it is determined whether the P-CSCF recovers from the failure. Specifically: if the response message is received, it is determined that the P-CSCF has recovered from the fault; if the response message is not received, it is determined that the P-CSCF has ...

Embodiment 2

[0068] Such as image 3 As shown, a registration control method provided by an embodiment of the present invention includes:

[0069] 301: The SBC sends a heartbeat detection message to the P-CSCF.

[0070] During specific implementation, the SBC may periodically send a heartbeat detection message to the P-CSCF until receiving a response message sent by the P-CSCF for the heartbeat detection message. Wherein, the heartbeat detection message may be SIP OPTIONS.

[0071] When step 301 is executed, the "P-CSCF" learned by the SBC is in a fault state, and steps 301-302 are executed to know whether the "P-CSCF" is in a recovery fault state.

[0072] 302: The SBC judges whether it has received a response message sent by the P-CSCF for the heartbeat detection message.

[0073] If yes, execute step 303; if not, execute step 301.

[0074] Specifically, the SBC judges whether a response message to the heartbeat detection message is received within a preset time period after step 301...

Embodiment 3

[0101] Such as Figure 4 As shown, it is a registration control device 4 provided by the embodiment of the present invention, which is used to execute figure 2 As shown in the registration control method, the device 4 includes:

[0102] The first detection unit 41 is configured to detect whether the proxy call session control entity P-CSCF recovers from a failure;

[0103] The receiving unit 42 is configured to receive the registration request message sent by the user equipment UE at the first moment;

[0104] The determining unit 43 is configured to, when the first detection unit 41 detects that the P-CSCF has recovered from a fault and the first moment determined by the receiving unit 42 is within a preset time period, include determining the P-CSCF to be registered for the UE in the P-CSCF group of the P-CSCF, so as to balance the load of each P-CSCF in the P-CSCF group;

[0105] The registration unit 44 is configured to register the UE with the P-CSCF to be registered ...

Abstract

The embodiment of the present invention discloses a registration control method and device, which relate to the communication field and are used to quickly realize the load balancing of each P-CSCF in the system when the P-CSCF recovers from a fault, so as to reduce some P-CSCF The probability of safety hazards caused by CSCF overload for a long time. The method provided by the embodiment of the present invention includes: detecting whether the P-CSCF recovers from the fault; receiving the registration request message sent by the user equipment UE at the first moment; after detecting that the P-CSCF has recovered from the fault, and the When the first moment is within the preset time period, determine the P-CSCF to be registered for the UE in the P-CSCF group including the P-CSCF, so that the load of each P-CSCF in the P-CSCF group Equalization: register the UE with the P-CSCF to be registered according to the registration request message. The embodiment of the present invention can be applied in IMS.

Description

[0001] The present invention relates to the communication field, in particular to a registration control method and device. Background technique [0002] IMS (IP Multimedia Subsystem, IP Multimedia Subsystem), as the standard of the next generation network, has nothing to do with communication and access, and can have a variety of media services, such as separation of control functions and carrying capacity, separation of calls and sessions, separation of services and networks, etc. ability. Such as figure 1 As shown, it is a schematic diagram of the architecture of IMS, including: UE (User Equipment, user equipment), SBC (Session Border Controller, session border controller), P-CSCF (Proxy call session control Function, proxy call session control entity), etc., wherein , the UE accesses the P-CSCF under the control of the SBC. For the functions of the above physical devices, please refer to relevant IMS standards. [0003] In order to provide users with high-quality and un...
