In order to make the objects, technical solutions, and advantages of the present invention more comprehensible, the present invention will be further described in detail below with reference to the embodiments and the accompanying drawings.

As shown in FIG. 1, a block diagram of a software system in a mobile terminal supporting IMS services is shown, wherein the location of the IMS client software module of the present invention in a software system of a mobile terminal (such as a mobile phone) is shown. Its composition. In FIG. 1 , a software system of a mobile terminal includes a mobile phone human-machine interface module, an IMS client software module, and a mobile phone operating system module, which are sequentially connected, wherein: a mobile phone human-machine interface module is configured to implement human-computer interaction on the mobile terminal. The interface, receiving information or control commands of the user's income or displaying the information that needs to be displayed to the user for the user to realize human-computer interaction, the mobile phone human-machine interface module also providing some other business applications;

An IMS client software module, configured to implement an IMS service-based interface, service logic, protocol signaling, and adaptation functions;

The mobile phone operating system module is configured to support the operation of the mobile phone software system through the operating system, and provides functional interfaces such as TCP/IP SOCKETS, timer management, memory management, file management, process/thread management, and message communication mechanism, and These functional interfaces are connected to the IMS client software module data;

Wherein, the mobile phone human-machine interface module and/or the mobile phone operating system module are connected through the functions thereof The port can actively invoke the function of the IMS client software module or provide an interface to the IMS client software module.

Further, as shown in FIG. 1, the IMS client software module specifically includes an adaptation layer, a signaling layer, a service logic layer, a service function interface layer, and data connections between layers, where:

(1) The adaptation layer is connected to the mobile phone operating system module through various system function interfaces, and is used to invoke a network function and an interface function of the mobile phone operating system, and send a request signaling packet sent by the signaling layer. Sending to the ip multimedia subsystem network, and receiving the request signaling data packet of the network response, and returning the received request signaling data packet to the signaling layer.

The adaptation layer directly communicates with the mobile phone support system, and calls the TCP/IP (Transmission Control Protocol/Internet Protocol) interface function provided by the mobile phone support system/mobile phone system, the timer interface function, the memory and file management interface function, and the process. / thread interface function, message mechanism interface function and other functions, to shield the physical characteristics of various mobile phones, the mobile phone operating system and the support system for the upper layer function, some of which, such as the timer interface function, can also The IMS client software module is implemented; at the same time, the adaptation layer provides interface calls for the upper layer functions, that is, provides encapsulated TCP/IP interface functions, timer interface functions, memory and file management interface functions, and process/thread interfaces. Function, message mechanism interface function.

The above mobile phone support system mainly refers to the mobile phone software platform, which is a package for mobile phone applications on the mobile phone operating system, such as BREW, etc.; some functions used by the adaptation layer, some of which can be provided by the mobile phone operating system, such as direct use on LINUX The socket function provided by the operating system. Since the adaptation layer is adapted to a variety of software platforms and operating systems, there is no specific platform or operating system in the present invention.

Among them, the adaptation layer provides three types of adaptation functions: TCP/UDP (Transmission Control Protocol/User Data Packet Protocol) adaptation, media function adaptation and other miscellaneous adaptation. Functions not related to TCP/UDP such as timer interface function, memory and file management interface function, and process/thread interface function are placed in other miscellaneous adaptation categories; receiving, transmitting voice/video messages, voice/video codecs (such as G.711, AMR, H.263, MPEG4, etc.), VoIP (Internet Protocol Voice) QoS (Quality of Service), etc. are placed in the media adaptation category.

(2) The signaling layer is configured to provide a signaling protocol support function, organize an assembly request signaling data packet, and forward the request signaling data packet to the adaptation layer for processing. The signaling layer implements a signaling protocol, and provides signaling interface functions for upper layer services, including signaling message assembly and encoding and decoding, and sending and receiving signaling messages. The signaling protocol that needs to be implemented includes:

The Session Initiation Protocol (SIP) includes SIGCOMP, SIMPLE, etc.

Session Description Protocol (SDP);

Real-time transport protocol / real-time transport control protocol (RTP/RTCP);

HTTP (Hypertext Transfer Protocol), XCAP (XML Configuration Access Protocol), MSRP; and assembly analysis of XML (Extensible Markup Language) used by signaling messages.

When sending or receiving a signaling message, the signaling layer is implemented by calling an interface function provided by the next layer of the adaptation layer; when the upper layer of the service logic layer needs to communicate with the device in the network, the interface provided by the layer is invoked. Features.

In addition, the signaling protocol provided by the signaling layer is independent of the service logic. The signaling layer and the service logic layer are respectively located at two different layers, so that the service logic layer can focus on implementing the service logic without paying attention to the implementation details of the signaling protocol, and the signaling layer uniformly implements various services with fewer resources. support.

(3) The service logic layer is configured to implement an IP multimedia subsystem client function, and deliver request signaling parameters to the signaling layer.

The IMS service implemented by the service logic layer includes a registration/deregistration, a voice over IP (VoIP), a group management (GM), a presence (Presence), an instant message (IM), a PoC, and the like. The related call relationships are minimized between the above services, and each service only provides the function call of the service to the upper layer. As for the mutual integration of various services, for example, the user clicks on a user whose status is "idle" on the interface. And sending an instant message to the "idle" user is implemented using a module such as a human interface.

The service logic in the service logic layer is responsible for maintaining the session state. For example, the SIP message of a VoIP call process is indicated by the service logic to indicate what message is sent by the signaling protocol layer. Since the client is opposite to the server, the above IMS client function includes many specific applications for communicating with the server, but it does not specifically refer to an application, such as instant messaging on the mobile phone. For a client, the video conference on the mobile phone is regarded as a client, and the mobile phone supporting VCC can also be regarded as a client. The present invention patent application mainly relates to a general system and method for implementing a client, and does not specifically refer to which server service client.

(4) the service interface function layer is configured to provide a calling interface of the IMS client software module to the mobile phone system, and send a service function request signaling;

The implementation manner of the service interface function layer providing a calling interface for the mobile phone system includes:

A. One is the way of the business plan;

Each IMS logic provides a complete interface, business logic, which can be used according to user actions by simply loading into the mobile application system;

B. Another way is to provide a business interface function or a message call;

MMI (Multimedia Interactive System) needs to provide related interface operations and display functions. On the mobile phone, MMI provides users with information prompts and responds to user operations on the mobile phone interface, and implements services by calling interface functions in the service interface layer.

The data communication manner between the internal layers of the IMS client software module and other modules is as shown in FIG. 2, based on the IMS client software modules shown in FIG. 1 and the description of each layer.

The data communication of the IMS client software module is divided into two functions: a function call and a message mechanism. The message mechanism depends on the message communication mechanism between the module and the process provided by the mobile phone operating system and the support system. The message mechanism module is mainly used to provide event notification functions, such as the response result of the request message, the service request sent on the network, and the like.

The adaptation layer includes a function of receiving a message from the network. After receiving the message from the network, the function encapsulates the client message into a message queue for distribution to the relevant functional layer. This feature can be implemented in a separate process. Among them, the message queue represents the way of data communication.

The message from the adaptation layer to the client internal message mechanism module is to send a response message to the signaling layer, and send the received multimedia message (such as an RTP message) to the media adaptation function;

The message from the client internal message mechanism module to the adaptation layer is a signaling message and a multimedia message (such as RTP^艮文) to be sent to the network; The message from the adaptation layer to the inter-module message mechanism module is used by the media adaptation function: sending the decoded multimedia message from the network to the media device (eg G.71 K AMR, H.263, MPEG4, etc.) ;

The message from the inter-module message mechanism module to the media adaptation function is a voice and video message (such as GSM-PRE-LTP, IS-95/QCELP voice) collected by the transmitting media device;

The message from the signaling layer to the client internal message mechanism module is a return response of the signaling message sent to the service logic layer;

The message from the client internal message mechanism module to the signaling layer is the message reported by the received adaptation layer, such as the signaling response returned by the network;

The message from the service logic layer to the client internal message mechanism module is a return response of the service request sent to the service function interface layer, and an RTP/RTCP message sent to the adaptation layer;

The message from the client internal message mechanism module to the service logic layer is a message received by the signaling layer, such as a signaling response returned by the network;

The service function interface layer receives the message from the client internal message mechanism module, which is the return response of the service request sent by the business logic layer, and the service function interface layer sends the response data to the inter-module message mechanism module to provide the MMI human-machine interface module. .

According to the above-mentioned framework function layering and message communication method, the function of each layered module in the framework is completed by at least one process (the adaptation layer can have two processes/threads for network connection and media message transmission respectively). Each process is assigned a number, the service function interface layer and the service within the service logic layer, and the protocol within the signaling layer will also be assigned a sub-number; the data structure of the message includes at least the message destination process number and sub-number, and the message source process. Number and subnumber, message content, etc.

The message queue outside the IMS client software module is established by the mobile phone platform for use by the MMI human interface module and the client; the mobile platform needs to provide an operation interface to the message queue. When the mobile phone system using the IMS client software of the solution starts, the startup function provided by the IMS client software module is called, and the startup function creates a shared memory area, a message queue, and various functional layer processes (threads or tasks), and then the The function returns. At this point, the entire IMS client is started, waiting for the service request command of the mobile system.

The above embodiment is applicable to 3GPP IMS (IMS based on the 3rd Generation Partnership Project Specification) Domain, 3GPP2 IMS (IMS based on the 3rd Generation Partnership Project 2 specification) domain.

FIG. 3 is a flowchart of a method for implementing a 3G IMS in a mobile phone according to the present invention, including: Step 301: Setting a 3G IMS client software module in the mobile phone;

Step 302: The service function interface layer analyzes the service function parameters according to the request signaling, and starts the software function of the corresponding service logic layer;

Step 303: The service logic layer performs a client function of the 3G IMS service, and transmits the request signaling parameter to the signaling layer.

Step 304: The signaling layer organizes the assembly request signaling data packet according to the received request signaling parameter, and delivers the request signaling data packet to the adaptation layer for processing;

Step 305: The adaptation layer invokes a network function and an interface function of the mobile operating system, sends a request signaling data packet sent by the signaling layer to the network, and receives a request signaling data packet of the network response, and then receives the received request. The signaling packet is returned to the signaling layer.

The above embodiment has been described by taking only a mobile phone as an example. The mobile phone in the present invention is broadly understood, that is, the mobile terminal having the equivalent wireless communication function can adopt the technical solution described in the present invention. For mobile terminals with other functions, devices such as PDA/mobile positioning devices, calling stations, etc. may also be equivalent to mobile phones herein.
