The IP multimedia subsystem architecture supporting the multi-service provided by the embodiment of the invention comprises the following steps: the system comprises an RCS application module, an RCS service module, a VoWiFi service module, an adaptation module and a multi-instance management module, wherein the RCS service module is used for providing an RCS service function for the RCS application module; the VoWiFi service module is used for providing a VoWiFi service function for the RCS application module; the adaptation module is used for packaging interfaces of each sub protocol stack in the IMS protocol stack; and the multi-instance management module is used for managing RCS sub-instances and VoWiFi sub-instances corresponding to each sub-protocol stack in the IMS protocol stack. Compared with the prior art, the method and the device can support the RCS service and the VoWiFi service to run on one IMS protocol stack on the terminal AP side, and the service processing efficiency is higher.
RCS and VoWiFi are network services based on IMS protocol stack, the requirements of these services on IMS protocol stack are basically identical, the IP multimedia subsystem architecture supporting multiple services provided by the invention adopts a design mode of single stack multiple services, namely, one IMS protocol stack is positioned at AP side, and simultaneously supports dual instances of RCS service and VoWiFi service, so that the code amount is greatly reduced, and the code utilization rate is high.
The schematic diagram of the IP multimedia subsystem architecture supporting multiple services provided by the present invention is shown in fig. 2, and the following describes each module in fig. 2 specifically:
RCS APP: RCS applications are provided, such as a messaging application, a dial application, a phonebook application, and the like.
RCS Service: the RCS service provides RCS basic capability for applications, for example, the RCS basic capability of IM instant information, File Transfer File transmission, Chat and the like is provided.
VoWiFi Service: the VoWiFi service provides basic capabilities of VoWiFi to applications, for example, services such as VoWiFi voice call, video call, SMS over IP, etc., wherein the VoWiFi voice call and the video call can be provided to the applications as new call functions of the RCS.
An Adapter: and the adaptation layer mainly has the function of encapsulating the interface of the lower IMS Stack for the use of the upper RCS Service and the VoWiFi Service.
Instance Manager: and the multi-instance management module is responsible for managing each instance. For example, to support two instances of RCS and VoWiFi at the same time, the present invention creates two instance management modules of INS _ RCS and INS _ VoWiFi, respectively. The two instance management modules include and manage RCS sub-instances and VoWiFi sub-instances corresponding to respective sub-protocols in an IMS protocol stack, for example, a corresponding RCS sub-instance in an SIP (Session initiation protocol) is an SIP _ INS _ RCS, and a corresponding VoWiFi sub-instance is an SIP _ INS _ VoWiFi.
IMS Stacks: the IMS Stack is a standard Protocol Stack, and provides a Protocol Stack transmission capability for an upper layer, and specifically includes important Protocol stacks such as an SIP, an SDP (Session Description Protocol), an XCAP (XML Configuration Access Protocol), an HTTP (HyperText Transfer Protocol), a DNS (domain name system), and the like.
The realization of the single-stack multi-service technology is based on the commonalities of all IMS protocols, the commonalities are extracted, then non-commonalities are extracted, such as differences of RCS and VoWiFi, and a structure body INS is established according to the differences so as to serve as a multi-instance standard.
The following takes the SIP protocol stack as an example to explain the design scheme of multiple instances:
SIP (session initiation protocol) is a multimedia communication protocol, which can support and be applied to multimedia services such as voice, video, data, etc. in IMS network, and can also be applied to feature services such as Presence service, IM instant messaging, etc. More specifically: SIP INVITE/BYE, etc., can be applied to VoWiFi calls; SIP MESSAGE, and is applied to the IM Service of RCS and the SMS over IP (Short Message Service over IP, IP network Short Message Service) Service of VoWiFi; SIP REGISTER, etc., are used in the registration of both RCS and VoWiFi.
The above SIP protocol stack relates to the same points of the different instances (RCS instance and VoWiFi instance): a SIP message processing flow, such as FSM (State Machine); encapsulation of SIP message bodies, etc., which do not differ depending on whether they are applied to RCS or VoWiFi, or to IM or SMS over IP. The invention writes these common parts into common sub-modules independent of the instance, such as FSM, Utility sub-modules, etc., for different instance operations.
The above SIP protocol stack relates to different points of different instances (RCS instance and VoWiFi instance): links, configurations, etc. used by the different instances; the contents of the SIP message body, etc. The invention respectively instantiates different parts of different instances (such as SIP _ INS _ RCS and SIP _ INS _ VoWiFi), the instantiated parts are placed in the SIP _ INS to serve as different sub-instances, and the specific values of the SIP _ INS owned by the different sub-instances are different. In addition, if necessary, a sub-module of the SIP _ INS can be added to process special operations of different instances, and the like.
And other protocol modules in the IMS protocol stack are designed in a multi-instance mode by taking SIP as an example.
According to the IMS single-stack multi-Instance design framework provided by the invention, an Instance Manager module is introduced to manage multiple instances, each protocol in an IMS protocol stack designs a sub-function module in the protocol according to a multi-instantiation standard, relevant contents are instantiated, and an Instance data structure is formed by stripping.
The multi-service supporting IP multimedia subsystem architecture provided by the present invention supports dual instances of RCS service and VoWiFi service at the same time, and is suitable for IMS dual registration or IMS single registration of RCS service and VoWiFi service, as shown in fig. 3, a schematic diagram of dual registration and single registration for RCS service and VoWiFi service. The important differences between IMS dual registration and single registration are: the dual registration is two access bearers, the RCS service is registered through a 4G/3G/2G PS Bearer (mobile cellular network access Bearer), and the VoWiFi service is registered through a VoWiFi IMS APN Bearer (Wi-Fi access Bearer); and the single registration only has one access Bearer, and the RCS service and the VoWiFi service share the VoWiFi IMS APN Bearer (Wi-Fi access Bearer) for registration.
The invention supports single registration or double registration of multiple services, no matter single registration or double registration, several services are registered, several examples are established, IMS protocol stack is divided according to the established examples, only when multiple services are registered, parameters related to paths of the multiple examples are consistent, and access load on the same path is used for transmitting data.
It will be understood by those skilled in the art that all or part of the processes of the methods of the embodiments described above can be implemented by a computer program, which can be stored in a computer-readable storage medium, and when executed, can include the processes of the embodiments of the methods described above. The storage medium may be a magnetic disk, an optical disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), or the like.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
