Description
The present invention relates to the field of communications, and in particular, to a registration control method and apparatus.
Background
The IMS (IP Multimedia Subsystem) is a standard for the next generation network, has a communication and access independence, and can have various capabilities such as separation of a plurality of media service control functions from a bearer capability, separation of a call and a session, and separation of a service from a network. As shown in fig. 1, it is a schematic diagram of an IMS architecture, which includes: a UE (User Equipment), an SBC (Session Border Controller), a P-CSCF (Proxy call Session control entity), and the like, wherein the UE accesses the P-CSCF under the control of the SBC. The functions of the entity devices can be referred to IMS related standards.
In order to provide high-quality uninterrupted service for users, the network needs to provide a disaster recovery mechanism for the UE; when the P-CSCF1 fails, the SBC needs to switch the UE registered to the P-CSCF1 to another normally operating P-CSCF (e.g., P-CSCF2) to reduce the service loss of the user; when the P-CSCF1 recovers from the failure, it is necessary to migrate the user traffic back to the failed P-CSCF1 in time to avoid other devices being in a high load state for a long time.
Currently, in a disaster recovery mechanism adopting load sharing, after a P-CSCF1 fails, an SBC selects and registers a new P-CSCF (e.g., P-CSCF2), and a corresponding relationship between the UE and the P-CSCF2 address is stored in its registration data area. When the P-CSCF1 recovers from the failure and the UE re-registers, the SBC will still register the UE to the P-CSCF2 according to the information stored in the registration data area; the SBC may register the UE with the failure-resilient P-CSCF, i.e., P-CSCF1, only if the UE deregisters and re-registers initially.
Since the time for deregistration of a UE is typically long, especially for a fixed UE, it is not usually deregistered unless it is powered off or restarted manually, and the network includes a large number of UEs, which may cause a safety hazard due to long-term overload of the P-CSCF 2.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
As shown in fig. 2, a registration control method provided for an embodiment of the present invention includes:
201: it is detected whether the proxy call session control entity P-CSCF recovers from the failure.
The registration control method provided by the embodiment of the invention can be applied to the IMS, and particularly can be applied to the scene of recovery failure of one or more P-CSCFs in the IMS. The execution subject of the embodiment of the present invention may be an SBC.
The embodiment of the present invention does not limit the specific implementation method of step 201, and optionally includes: SBC sends heartbeat detection message to P-CSCF; and the SBC determines whether the P-CSCF recovers from the fault according to whether a response message aiming at the heartbeat detection message sent by the P-CSCF is received or not. Specifically, the method comprises the following steps: if the response message is received, determining that the P-CSCF has recovered from the failure; and if the response message is not received, determining that the P-CSCF is not recovered from the failure.
202: and receiving a registration request message sent by User Equipment (UE) at a first moment.
The "registration request message" may be an initial registration request message or a re-registration request message. Generally, when a UE in a system initially registers, an initial registration request message is sent to an SBC; the registered UE sends a re-registration request message to the SBC once at the end of each re-registration period. When the "registration request message" is an initial registration request message, the "UE" may be any unregistered UE; when the registration request message is a re-registration request message, the UE may be any UE that has been registered, for example, a UE that was registered on the P-CSCF or other P-CSCFs before the failure of the P-CSCF in step 201.
203: and when the P-CSCF is detected to be recovered from the fault and the first time is within a preset time period, determining the P-CSCF to be registered of the UE in a P-CSCF group containing the P-CSCF so as to balance the load of each P-CSCF in the P-CSCF group.
In a specific implementation, a timer may be set in the system, and a start trigger condition (for example, when the P-CSCF has recovered from the failure) and an end trigger condition (i.e., when the timer is started for a preset period of time) of the timer may be set. In this case, step 203 may be implemented as: when the timer is in an open state, if the SBC receives a registration request message sent by the UE, the SBC determines a P-CSCF to be registered of the UE in a P-CSCF group containing the P-CSCF, so as to balance the load of each P-CSCF in the P-CSCF group. In addition, when the timer is in the closed state, the SBC determines the P-CSCF to be registered of the UE according to the method in the prior art. The timer may be set in the SBC or may be independent of the SBC.
Optionally, the preset time period is 2 to 3 re-registration periods from a second time, where the second time is a time when the P-CSCF is detected to recover from the failure. Of course, the preset time period may be other time periods.
In order to provide high quality uninterrupted service to the user, optionally, after step 202, the method may further include: detecting whether the UE is executing a service; in this case, step 203 may include: and when the P-CSCF is detected to be recovered from the fault, the first time is within a preset time period, and the UE does not execute the service, determining the P-CSCF to be registered of the UE in a P-CSCF group containing the P-CSCF. The service may be any one or more services, and the embodiment of the present invention does not limit the specific type of the service. Further optionally, the service is a call service, and in this case, detecting whether the UE is executing the service may include: detecting whether a calling data area contains the identity of the UE; specifically, the SBC detects whether a local call data area includes the identifier of the UE.
Optionally, the SBC may determine the P-CSCF to be registered of the UE in the P-CSCF group including the P-CSCF in a dynamic query manner or a static query manner. Specifically, the method comprises the following steps: the dynamic query mode may include: SBC sends request message to ENUM/DNS server; wherein the request message is used for enabling the ENUM/DNS server to determine a P-CSCF to be registered for the UE in a P-CSCF group containing the P-CSCF; and receiving a response message which is returned by the ENUM/DNS server and contains the information of the P-CSCF to be registered. The static query mode may include: and locally configuring a P-CSCF list consisting of a P-CSCF group containing the P-CSCF at the SBC, and determining the P-CSCF to be registered of the UE from the P-CSCF list according to a certain principle (such as a load balancing principle, a priority principle and the like).
204: and registering the UE to the P-CSCF to be registered according to the registration request message.
Wherein step 204 may be implemented as: sending the registration request message to the P-CSCF to be registered; the subsequent process can be referred to as a registration process in the prior art.
In the registration control method provided by the embodiment of the invention, when the P-CSCF is detected to be recovered from the fault and the time for receiving the registration request message of the UE is within the preset time period, the P-CSCF to be registered is selected for the UE in the P-CSCF group containing the P-CSCF which recovers the fault, so that the load of each P-CSCF in the P-CSCF group is balanced. By using the scheme, if the UE which is re-registered to the P-CSCF2 due to the fault of the P-CSCF1 sends the re-registration request message within the preset time period after the fault of the P-CSCF1 is recovered, the UE can be registered to other P-CSCFs except the P-CSCF2, so that the load of the P-CSCF2 is reduced, the load balance of each P-CSCF in the system is quickly realized, and the probability of potential safety hazards caused by long-time overload of the P-CSCF2 is reduced.
Example two
As shown in fig. 3, a registration control method provided for an embodiment of the present invention includes:
301: the SBC sends a heartbeat detection message to the P-CSCF.
In a specific implementation, the SBC may periodically send a heartbeat detection message to the P-CSCF until receiving a response message for the heartbeat detection message sent by the P-CSCF. Wherein, the heartbeat detection message may be SIP OPTIONS.
In step 301, the SBC knows that the "P-CSCF" is in a failure state, and step 301 and step 302 are executed to know whether the "P-CSCF" is in a recovery failure state.
302: the SBC determines whether a response message to the heartbeat detection message sent by the P-CSCF is received.
If yes, go to step 303; if not, go to step 301.
Specifically, the SBC determines whether a response message to the heartbeat detection message is received within a preset time period after performing step 301, and the response message may be a 200 OK message.
303: the SBC determines that the P-CSCF has recovered from the failure and starts a timer.
Before step 303 is executed, the timer is in an off state, and after the SBC starts the timer, the timer is changed from the off state to an on state. The timer automatically changes from the on state to the off state within a preset time period after being turned on.
304: the SBC receives a registration request message sent by the UE.
In a specific implementation, the SBC executes step 304 at a time that is independent of the time that is executed in steps 301 and 303, that is, the SBC receives the registration request message sent by the UE regardless of whether the P-CSCF recovers from the failure. If the P-CSCF is not recovered from the failure, the SBC determines the P-CSCF to be registered for the UE according to the method in the prior art.
305: the SBC determines whether the timer is in an on state.
If yes, go to step 306; if not, go to step 311.
306: the SBC determines whether the local call data area contains the identifier of the UE.
If not, it indicates that the UE is not executing the call service, i.e. is not in a call, then step 307 is executed; if yes, it indicates that the UE is talking, go to step 311.
The "call data area" may be located in a storage unit of the SBC, and is used for recording the identity of the UE in a call in the system.
307: the SBC determines the P-CSCF query mode.
If the P-CSCF query mode is the dynamic query mode, go to step 308; if the P-CSCF query mode is the static query mode, step 310 is executed.
Generally, each SBC may determine a P-CSCF to be registered in a static query manner, and an SBC having an ENUM/DNS function may determine a P-CSCF to be registered in a dynamic query manner.
308: SBC sends request message to ENUM/DNS server; wherein the request message is used for enabling the ENUM/DNS server to determine the P-CSCF to be registered of the UE in the P-CSCF group containing the P-CSCF.
The "ENUM/DNS server" is a network element that is functionally combined by an ENUM (Telephone Number mapping group) server and a DNS (Domain name system) server.
Specifically, the ENUM/DNS server may determine the P-CSCF to be registered for the UE in the P-CSCF group including the P-CSCF according to the load balancing principle.
309: the SBC receives a response message which is returned by the ENUM/DNS server and contains the information of the P-CSCF to be registered. The information of the P-CSCF to be registered may be: the address of the P-CSCF to be registered.
After step 309 is performed, step 312 is performed.
310: and the SBC determines the P-CSCF to be registered of the UE in the P-CSCF group containing the P-CSCF according to the principle of load balancing.
After step 310 is performed, step 312 is performed.
311: the SBC inquires the address of the P-CSCF corresponding to the identity of the UE in the registration data area, and takes the P-CSCF corresponding to the address as the P-CSCF to be registered.
Note that, this step 311 is a registration control method in the related art.
312: the SBC sends a registration request message to the P-CSCF to be registered to register the UE with the P-CSCF to be registered.
After step 312 is performed, it is ended.
In a specific implementation, after step 312, the method may further include: the P-CSCF to be registered performs information interaction with devices such as an I-CSCF (Interrogating-call session control entity), an S-CSCF (Serving-CSCF, Serving call session control entity), and an HSS (Home Subscriber Server) in the system to connect the UE to the network.
In the registration control method provided in the embodiment of the present invention, when an SBC receives a registration request message sent by a UE within a preset time period after detecting that a P-CSCF has recovered from a failure, if the UE is not in a call, a P-CSCF to be registered is selected for the UE in a P-CSCF group including the P-CSCF that has recovered from the failure, so as to balance the load of each P-CSCF in the P-CSCF group. By using the scheme, if the UE which is re-registered to the P-CSCF2 due to the fault of the P-CSCF1 sends the re-registration request message within the preset time period after the fault of the P-CSCF1 is recovered, the UE can be registered to other P-CSCFs except the P-CSCF2, so that the load of the P-CSCF2 is reduced, the load balance of each P-CSCF in the system is quickly realized, and the probability of potential safety hazards caused by long-time overload of the P-CSCF2 is reduced. In addition, the scheme does not reselect the P-CSCF of the UE in the conversation, so that high-quality uninterrupted service is provided for the UE in the conversation under the condition of quickly realizing the load balance of each P-CSCF in the P-CSCF group, and the user experience is improved.

In the registration control apparatus provided in the embodiment of the present invention, when it is detected that the P-CSCF has recovered from the failure and a time of receiving a registration request message of a UE is within a preset time period, a P-CSCF to be registered is selected for the UE in a P-CSCF group including the P-CSCF that has recovered from the failure, so that loads of P-CSCFs in the P-CSCF group are balanced. By using the device, if the UE which is re-registered to the P-CSCF2 due to the fault of the P-CSCF1 sends a re-registration request message within a preset time period after the fault of the P-CSCF1 is recovered, the UE can be registered to other P-CSCFs except the P-CSCF2, so that the load of the P-CSCF2 is reduced, the load balance of each P-CSCF in the system is quickly realized, and the probability of potential safety hazards caused by long-time overload of the P-CSCF2 is reduced.
