Therefore, the conventional upgrade mode cannot avoid call loss for the ongoing service, so that the ongoing service is suddenly interrupted. Under the background requirement of NFV (Network Functions Virtualization) translated into network function virtualization, the traditional upgrade mode obviously cannot meet the full-service operation requirement of a new system and a new network architecture, and the lossless upgrade of multiple services becomes the problem which must be solved at present

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 shows a block diagram of a SIP signaling front-end processor according to an embodiment of the present invention. SIP (Session Initiation Protocol ) signaling front-end processor is mainly used for service distribution, and distributes received service messages to at least two service processing modules (only two service processing modules are shown in fig. 1 by way of example, but not limited thereto) for processing. As shown in fig. 1, the SIP signaling front-end processor includes: a SIP function module 110, a service configuration module 120, a service identification module 130, a designation distribution module 140, a load sharing module 150, and an internal communication module 160.
The SIP function module 110 is configured to receive and parse a service call, and send the parsed service call to the service identification module. When the system receives the call signaling of the CSCF (Call Session Control Function ) network element, the SIP function module receives and parses the service call, where the system refers to a system where the SIP signaling front-end is located, for example, if the SIP signaling front-end is located in an AS (Application Server ) application module in an IMS (IP Multimedia Subsystem, IP multimedia system) network, the system is an AS application module.
Wherein the service configuration module 120 is configured to receive the specified distribution configuration information. The default distribution mode of the SIP signaling front-end processor provided by the invention is according to the distribution of the service load, namely, a plurality of service calls are uniformly distributed to a plurality of service processing modules, so as to realize the load balance; meanwhile, the SIP signaling front-end processor also provides a mode for distributing according to a designated distribution mode, so as to be used for carrying out service upgrading. The service configuration module 120 may set the designated distribution configuration information, and the service configuration module 120 may import the designated distribution configuration information to the service identification module 130 and the designated distribution module 140, so as to implement distribution according to the designated distribution manner.
The service identification module 130 is configured to set a specified distribution identifier according to the specified distribution configuration information, and forward a new service call received after the specified distribution identifier is set to the specified distribution module. If the service identification module 130 receives the designated distribution configuration information imported by the service configuration module 120, the designated distribution identifier is set, otherwise, the designated distribution identifier is not set; and after receiving the new service call sent by the SIP function module, it detects whether the module has the designated distribution identifier at this time, if so, it indicates that the module is at the service upgrade stage at this time, and forwards the service call to the designated distribution module 140.
The designated distribution module 140 is configured to set a corresponding distribution model according to the designated distribution configuration information, and send the new service call and the distribution model to the load sharing module 150. The designated distribution module 140, upon receiving the designated distribution configuration information imported by the service configuration module 120, generates a distribution model corresponding to the designated distribution configuration information to instruct the load sharing module 150 how to distribute the new service call.
Wherein, the load sharing module 150 is configured to determine, according to the distribution model, a target service processing module that processes the new service call. For example, if the distribution model indicates that the service call is sent to the first service processing module, it is determined that the target service processing module is the first service processing module. Then, the identification information of the target service processing module and the new service call are transmitted to the internal communication module. It should be noted that, if the distribution model indicates that the service call is distributed to a certain service processing module, the load sharing module 150 directly determines that the target service processing module is the certain service processing module according to the indication of the distribution model; if the distribution model indicates that the service call can be distributed to a plurality of service processing modules, the load sharing module 150 needs to further determine the target service processing module from the plurality of service processing modules in a load balancing manner based on the distribution model. For example, if the service processing module 1 is currently upgraded, the distribution model may instruct to distribute the service call to any one of the remaining service processing modules 2 and 3, and the load sharing module 150 may determine the target service processing module according to the load pressures of the service processing modules 2 and 3, so as to ensure load balancing.
The internal communication module 160 is configured to send the new service call to a target processing module pointed by the identification information in at least two service processing modules for processing.
The SIP signaling front-end processor can distribute the received new service call to the appointed service processing module by setting the appointed distribution configuration information through the service configuration module, and the other service processing modules do not bear the service call, so that the SIP signaling front-end processor can be used for carrying out service upgrading on the other service processing modules, and the call service is not interrupted in the upgrading process.
Meanwhile, the SIP signaling front-end processor provided by the invention can also be used for carrying out service distribution according to a default distribution mode, namely a mode of distributing service load under the condition of normal service call flow (namely non-service upgrading). As shown in fig. 1, the service identifying module 130 is further configured to forward the service call received before the specified distribution identifier is set to the load sharing module, in other words, after the service identifying module 130 receives the call service sent by the SIP function module, it detects that the specified distribution identifier does not exist in the module, and sends the call service to the load sharing module 150; the load sharing module 150 is further configured to determine a target processing module for processing the service call sent by the service identification module 130 according to the service load distribution manner, so as to ensure load balancing of at least two service processing modules in the normal service call process.
In addition, in the SIP signaling front-end processor shown in fig. 1, for the service message sent by the service processing module to the CSCF, after the internal communication module 160 receives the service message, the service message is directly sent to the CSCF by the SIP function module 110, without going through the load sharing module
The SIP signaling front-end processor shown in fig. 1 can be used for distributing service calls to at least two service processing modules in average through the SIP function module, the service identification module, the load sharing module and the internal communication module in sequence in a normal service call flow, so as to meet the performance requirement of a large-capacity SIP call service and realize the efficient processing of service calls; and in the call flow of service upgrading, the service call sequentially passes through the SIP function module, the service identification module, the appointed distribution module, the load sharing module and the internal communication module and is distributed to the appointed service processing module, and the service is not interrupted, thereby being beneficial to realizing the service upgrading without call loss. Therefore, the SIP signaling front-end processor can give consideration to the processing performance in the normal service call flow and the service upgrading without call loss.
Fig. 2 shows a flowchart of a service upgrade method provided by an embodiment of the present invention. The method is realized based on the SIP signaling front-end processor, wherein the SIP signaling front-end processor is used for distributing a plurality of service calls to at least two service processing modules for processing. As shown in fig. 2, the method comprises the steps of:
Step S210: when the service upgrading requirement exists, an initial module to be upgraded is selected from at least two service processing modules.
In this embodiment, the service processing modules are mainly exemplified by two cases, but in practical implementation, the service processing modules are not limited to this, and multiple cases can be implemented by analogy of two cases. After replacing all the service processing modules with updated service processing modules, one service upgrade is completed, and the upgraded service processing modules can be used for processing service calls.
Specifically, each time a part of service processing modules are selected as the modules to be upgraded to perform upgrading processing, the rest of service processing modules can continue to perform normal service processing so as to avoid service interruption. In this step, the module to be upgraded is selected randomly from at least two service processing modules, or by module number, or by module configuration.
Step S220: setting distribution configuration information of the SIP signaling front-end processor to be distributed to at least one other service processing module except the module to be upgraded; if a new service call is received, the SIP signaling front-end processor distributes the new service call to the at least one other service processing module for processing according to the distribution configuration information.
Specifically, the service configuration module of the SIP signaling front-end processor sets the distribution configuration information as a designated distribution mode, and designates distribution to at least one other service processing module except the to-be-upgraded module, where the to-be-upgraded module does not carry a service call, and the at least one other service processing module may be all the remaining service processing modules or may be the remaining partial service processing modules. After the designated distribution mode is set, if a new service call is received, the SIP signaling front-end unit works in a service upgrade mode at this time, that is, the new service call is distributed to at least one designated other service processing module for processing through the SIP functional module, the service identification module, the designated distribution module, the load sharing module and the internal communication module (specifically, the distribution processing can be referred to the description about the module working principle and the process of the SIP signaling front-end unit in fig. 1), wherein if at least one other service processing module is one, the new service call is directly distributed to the module, and if a plurality of service processing modules are needed, one service processing module is selected for distribution according to the service load.
For example, selecting the service processing module 1 of the two service processing modules as the module to be upgraded, setting the distribution configuration information to be designated and distributed to the service processing module 2, and then, the received new service call is processed by the SIP function module of the SIP signaling front-end processor, the service identification module, the designated and distributed module, the load sharing module and the internal communication module, and finally, distributed to the service processing module 2 for processing.
Step S230: waiting for the end of the service call processing distributed to the module to be upgraded; and after waiting for finishing, replacing the module to be upgraded by using the updated service processing module.
After setting distribution configuration information designated to be distributed to at least one other service processing module, waiting for service call processing that has been previously distributed to the module to be upgraded to end, and then performing module replacement, avoiding the influence of processing procedures that cause service calls that have been previously distributed to the module to be upgraded to set the above-described distribution configuration information, for example, causing call interruption. In other words, after the designated distribution configuration information is set, for the newly received service call, the service call is distributed to at least one other service processing module for processing through the SIP signaling front-end processor; and for the service calls distributed to the module to be upgraded, continuing to process the service calls by the module to be upgraded until all the service calls in the module to be upgraded are processed.
After the service call is assigned to be distributed to the service processing module 2, the service processing module 1 waits for the service call to be distributed to the service processing module 1 (i.e. the module to be upgraded) to complete the processing of the distributed service calls, for example, in step S220.
And after all the service calls distributed to the modules to be upgraded are processed, replacing the modules to be upgraded by the updated service processing modules prepared in advance, wherein the updated service processing modules have the service functions of upgrading.
Step S240: judging whether all the at least two business processing modules are upgraded; if yes, the service upgrading is completed, and the method is ended; if not, step S250 is performed.
After the step S220 and the step S230, the upgrade of the module to be upgraded is completed, and if at least two service processing modules are not completely upgraded, step S250 is required to be executed to select a new module to be upgraded and continue to upgrade; if at least two service processing modules are completely upgraded, the whole service is upgraded, and the method is finished.
Step S250: and selecting an unselected module to be upgraded from the at least two service processing modules, and repeatedly executing the steps S220 to S240.
And continuing to randomly select the module to be upgraded which is not selected according to the module number or the module configuration, and repeating the processes from the step S220 to the step S260 to upgrade the currently selected module to be upgraded. For example, in the case of two service processing modules, if the upgrade for the service processing module 1 is completed, the service processing module 2 is selected as a new module to be upgraded.
According to the service upgrading method provided by the embodiment, the method is realized based on the SIP signaling front-end processor disclosed in the previous embodiment, when the service upgrading requirement exists, the to-be-upgraded module in at least two service processing modules is upgraded each time, and the designated distribution configuration information is set through the SIP signaling front-end processor, so that the service call is not born in the upgrading process of the to-be-upgraded module, and the newly received service call is distributed to other service processing modules for processing, thereby avoiding service interruption; and for the service call distributed to the module to be upgraded, the upgrade replacement can be performed after the processing is completed, so that the normal processing of the part of service call is ensured. Therefore, the service upgrading without call loss can be realized through the SIP signaling front-end processor according to the scheme of the embodiment.
Fig. 3 is a flowchart of a service upgrade method according to another embodiment of the present invention. As shown in fig. 3, the method includes:
step S310: when the service upgrading requirement exists, an initial module to be upgraded is selected from at least two service processing modules.
Step S320: setting distribution configuration information of the SIP signaling front-end processor to be distributed to at least one other service processing module except the module to be upgraded; if a new service call is received, the SIP signaling front-end processor distributes the new service call to the at least one other service processing module for processing according to the distribution configuration information.
Step S330: waiting for the end of the service call processing distributed to the module to be upgraded; and after waiting for finishing, replacing the module to be upgraded by using the updated service processing module.
Step S340: and restoring the distribution configuration information of the SIP signaling front-end processor to distribute according to the service load, and carrying out service distribution by the SIP signaling front-end processor according to the restored distribution configuration information.
In this embodiment, after the upgrade of the module to be upgraded is completed, the default distribution mode (according to the service load distribution) of the SIP signaling front-end processor is restored, and in this distribution mode, the SIP signaling front-end processor sequentially passes through the SIP function module, the service identification module, the load sharing module and the internal communication module of the SIP signaling front-end processor, and the SIP signaling front-end processor distributes the service call to the currently upgraded service processing module and at least one other service processing module on average. In this way, after the upgrade of part of the service processing modules is completed, the average distribution can be restored, so that the load is equally distributed to each service processing module, so that the pressure of at least one other service processing module is shared before the next upgrade of the module to be upgraded is entered, and the upgraded module can accept a new service call.
In practice, the service processing modules before and after upgrading may not be compatible, and in some alternative embodiments, for the problem, after the to-be-upgraded module is replaced by the updated service processing module for the initial to-be-upgraded module, whether the to-be-upgraded module is compatible with the upgraded service processing module is judged, if it is judged that the to-be-upgraded module is compatible with the upgraded service processing module, after the upgrading of the to-be-upgraded module is completed each time, the distribution configuration information of the SIP signaling front-end processor is restored to be distributed according to the service load, so that the service load is distributed evenly on the premise of ensuring the compatibility. Otherwise, if the to-be-upgraded module and the upgraded service processing module are not compatible, after the upgrading of the to-be-upgraded module is completed each time, setting the distribution configuration information of the SIP signaling front-end processor to be appointed to be distributed to the upgraded service processing module, and then distributing the newly received service call to the upgraded service processing module for processing, so that the service call can be prevented from being uniformly distributed to the incompatible service processing module, and meanwhile, the updated service processing module can be ensured to be used for processing the new service call.
For example, at least two service processing modules, namely, a module 1, a module 2 and a module 3, are three, respectively, if one module to be upgraded is selected in the above order each time, that is, the module 1 is an initial module to be upgraded, after the upgrade of the module 1 is completed by using the steps S310 to S330, it is determined whether the modules 1 before and after the upgrade are compatible, if the modules 1, the modules 2 and the modules 3 are compatible, the distribution configuration information of the SIP signaling front-end processor is restored to be distributed according to the service load after the upgrade of the module 1 is completed, wherein, after the upgrade of the module 1 is completed, the service call is uniformly distributed to the modules 1, 2 and 3 after the upgrade; after the upgrade of the module 2 is completed, the service call is uniformly distributed to the upgraded module 1, the upgraded module 2 and the upgraded module 3; after the upgrade of the module 3 is completed, the service call is equally distributed to the upgraded module 1, the upgraded module 2 and the upgraded module 3. Otherwise, if not compatible, after the upgrade of the module 1, the module 2 and the module 3 is respectively finished, setting the distribution configuration information of the SIP signaling front-end processor to be appointed to be distributed to the upgraded service processing module, wherein after the upgrade of the module 1 is finished, the service call is distributed to the upgraded module 1; after the upgrade of the module 2 is completed, distributing the service to the upgraded module 1 and the upgraded module 2 (which can be equally divided); after the upgrade of the module 3 is completed, the service is distributed to the upgraded module 1, the upgraded module 2, and the upgraded module 3 (which may be equally divided).
Step S350: judging whether all the at least two business processing modules are upgraded; if yes, the service upgrading is completed, and the method is ended; if not, step S360 is performed.
Step S360: and selecting an unselected module to be upgraded from the at least two service processing modules, and repeatedly executing the steps S320 to S350.
In this embodiment, except for step S340, the steps not described in detail can be specifically referred to the corresponding steps in the embodiment corresponding to fig. 2, and will not be described herein.
According to the service upgrading method provided by the embodiment, after the upgrading of the module to be upgraded is completed each time, the distribution configuration information of the SIP signaling front-end processor can be restored to be distributed according to the service load, the SIP signaling front-end processor can distribute the service according to the restored distribution configuration information, after the upgrading of part of service processing modules is completed, the service processing modules can be restored to average distribution, the load is evenly distributed to each service processing module, so that the pressure of at least one other service processing module is shared before the next upgrading of the module to be upgraded is carried out, and meanwhile, the upgraded module can accept a new service call. Furthermore, the service load distribution can be restored only when the service load is compatible before and after upgrading through compatibility judgment, so that the service load is distributed evenly on the premise of ensuring the compatibility.
To facilitate understanding of the foregoing embodiments of the service upgrade method and the effects thereof, the following description is given with a complete SIP signaling example:

(3 a.5) - (3 a.8): the first service processing module and the second service processing module send out a temporary response message 100 transmission to the calls of the user a and the user b through the SIP signaling front-end processor.

(3 a.21) - (3 a.28): the call release message processing of the user a and the user b is equally processed by adopting load sharing to the first service processing module and the second service processing module.
Fig. 4b shows a flow chart of the upgrade procedure in case of two service processing modules. Wherein the SIP signaling is processed as per the service call flow in fig. 4a before the upgrade (i.e. before the specified distribution mode is set). As shown in fig. 4b, the specific flow is as follows:
