Description

Short message center equipment integrating GSM network and CDMA network and its realization method

The invention belongs to the field of mobile communication, specifically, a device for providing short message service in a mobile communication network and a method for realizing short message intercommunication between GSM network and CDMA network.

In the second-generation mobile communication system, GSM digital mobile communication network (hereinafter referred to as GSM network) and narrowband CDMA digital mobile communication network (hereinafter referred to as CDMA network) are the most important and common two types, except voice service and data service , both can provide short message service for their mobile phone users. In the structures of these two networks, there is an independent short message center entity, which is the core functional entity to realize the short message service. The GSM network short message center has similar functions to the CDMA network short message center, both of which provide short message submission, storage, delivery, retry and other functions. However, because the GSM network and the CDMA network are independent of each other and use different signaling protocols, and there are also large differences in the short message content structure of the GSM network and the CDMA network, the short message center of the GSM network cannot be directly applied to the CDMA network. ,vice versa. GSM mobile phones and CDMA mobile phones cannot send and receive short messages to each other.

At present, no patent documents discussing and solving the above problems have been retrieved.

The purpose of the present invention is to realize a kind of short message center equipment (hereinafter referred to as one short message center), which can provide short message service for GSM network and CDMA network simultaneously. Another purpose of the present invention is to propose a method for utilizing the above-mentioned unified short message center to carry out GSM network and CDMA network short message unification processing, and realize the short message intercommunication of GSM mobile phone and CDMA mobile phone.

The unified short message center equipment that the present invention proposes comprises:

Signaling processing front-end: responsible for processing No. 7 signaling, providing No. 7 interface to the outside, connecting with GSM network/CDMA network through No. 7 signaling network, and interacting with No. 7 signaling with MSC, HLR and other entities.

Service processor: responsible for user authentication, short message submission, storage, forwarding and other processing.

Database: Responsible for storing account opening user data and short message data.

Business reception desk: responsible for managing user information and data, and completing user account opening and other functions.

Operation and maintenance station: responsible for system monitoring and maintenance.

The method for realizing the unified processing of the short messages of the GSM network and the CDMA network proposed by the invention includes two processes of receiving the short message and sending the short message by the integrated short message center.

The process of receiving short messages is divided into the following steps:

1. The Heyi short message center receives the short message submitted by the user through the signaling network;

2. The short message center unpacks the packet structure of the message, and judges according to the message label;

3. According to the result of judgment, the short message from the GSM network is sent to the GSM MAP processing process, and after codec processing, it is delivered to the GSM short message processing unit in the service processor for processing. The short message from the CDMA network is sent to the CDMA MAP signaling signaling processing process, and after codec processing, it is handed over to the CDMA short message processing unit in the service processor for processing.

4. GSM short message processing unit judges the destination of short message, if be GSM network user, then send to user by GSM network entity, if be CDMA network user, then carry out the format conversion of short message, send to CDMA short message processing unit , sent to the user through the CDMA network entity. CDMA short message processing unit judges the destination of short message, if be CDMA network user, then send to user by CDMA network entity, if be GSM network user, then carry out the format conversion of short message, send to GSM short message processing unit, pass GSM network entities send to users.

The process of sending a short message by the integrated short message center is divided into the following steps:

1. The Heyi short message center receives short messages submitted by other short message entities ESME through the SMPP proxy service.

2. The short message center analyzes the network where the target user is located.

3. If the destination user is located in the GSM network, then send to the GSM short message processing unit, and send to the destination user through the GSM network; if the destination user is located in the CDMA network, then send to the CDMA short message processing unit, and send to the destination user through the CDMA network.

In the GSM network and the CDMA network, the short message center is an independent entity shared by the two networks. It utilizes No. 7 signaling to interact with other entities in the mobile communication network (such as the home location register HLR, mobile switching center MSC, etc.) Certain signaling specifications complete short message services, including: receiving short messages submitted by mobile phones, delivering short messages to mobile phones, and receiving prompts from the network that "the mobile phone can receive short messages", etc.

The present invention will be described in detail below in conjunction with the accompanying drawings.

Figure 1 is a network reference model;

Fig. 2 is a structural diagram of the combined short message center system;

Fig. 3 is a schematic diagram of the realization method of the integrated short message center.

In Figure 1, as a common entity of the GSM network and the CDMA network, the Heyi short message center can interact with the entities (MSC, HLR, etc.) The short message sending and receiving of the GSM network or the CDMA network can also realize the interconnection and intercommunication of the short messages of the GSM network and the CDMA network through the interaction with other entities in the two networks.

Figure 2 shows the structural diagram of the combined short message center equipment. The integrated short message center equipment includes modules such as signaling processing front-end processor, business processor, database, operation and maintenance console, and business acceptance console. Each module of the Heyi short message center uses high-speed Ethernet to communicate and cooperate with each other. In order to ensure the reliable operation of the system, the two business processors in Figure 2 work in a load-bearing manner. The data query, storage and modification are performed between the business processor and the database through the Ethernet, using the client/server method.

In Fig. 2, the system can also connect to the external short message entity ESME by connecting the SMPP proxy server.

Fig. 3 describes the realization method of the integrated short message center.

Since the No. 7 signaling system adopts a layered functional structure, it includes message transfer part (MTP), signaling connection control part (SCCP), transaction processing capability application part (TCAP) and various services related to specific services from bottom to top. Therefore, in the signaling processing front-end processor, there are corresponding processing sub-modules for each layer, and the signaling messages are processed layer by layer.

The No. 7 signaling adopted by GSM network and CDMA network is the same at the MTP layer and SCCP layer, but there is a big difference at the TCAP layer. The GSM network adopts the European ITU standard, and the CDMA network adopts the North American ANSI standard. Therefore, there are two different TCAP signaling processing sub-modules in the signaling processing front-end. For bottom-up signaling messages, analysis and identification are required. These analysis and identification can be in MTP or SCCP or add corresponding functional modules. Carry out, send message to correct TCAP signaling processing submodule, promptly the signaling message from GSM network is sent to TCAP (ITU standard) signaling processing submodule, and the signaling message from CDMA network is sent to TCAP (ANSI Standard) signaling processing sub-module.

In the present invention, after receiving the signaling message sent by other network entities, the signaling processing front end opens the message body of the upper layer TCAP message contained in it, and judges according to the message type mark therein. The TCAP message in the national standard The message type tag is defined as follows:

00: General (application-independent type);

01: All common (all TC-users);

10: contextual application (markup in structure);

11: Dedicated (one country, one network, or one dedicated user).

Currently, the ITU standard TCAP adopts the mark 01, while the ANSI standard TCAP adopts the mark 11 (the mark values 00 and 10 are used for other applications). Therefore, the signaling processing front-end processor can judge whether the message is from the GSM network or the CDMA network according to the difference in the TCAP message label, so that the message can be sent to the correct TCAP signaling processing sub-module.

The specific method to realize the integration of short message center is:

The short message submitted by the GSM mobile phone is sent to the GSM MAP signaling processing submodule through the MTP signaling processing submodule, SCCP signaling processing submodule, and TCAP (ITU standard) signaling processing submodule, and then transferred to the GSM service of the service processor The processing sub-module performs user authentication and short message analysis. If the destination address of this message is a CDMA mobile phone, then the GSM service processing submodule first carries out message format conversion, and then the message is forwarded to the CDMA service processing submodule, and the CDMA service processing submodule is responsible for delivery to the CDMA mobile phone; if the message's The destination address is still a GSM mobile phone, then the GSM service processing submodule sends the short message to the GSM MAP signaling processing submodule, and this module is responsible for finding routing and forwarding the short message. The signaling message for routing is sent to the destination user HLR (GSM network) located in the No. 7 signaling network through the TCAP (ITU standard) signaling processing submodule, SCCP signaling processing submodule, and MTP signaling processing submodule, and forward The signaling message of the short message is also sent to the destination user visiting MSC (GSM network) located in the No. 7 signaling network through the TCAP (ITU standard) signaling processing submodule, the SCCP signaling processing submodule, and the MTP signaling processing submodule.

The short message submitted by the CDMA mobile phone is sent to the CDMA MAP signaling processing sub-module through the MTP signaling processing sub-module, SCCP signaling processing sub-module, and TCAP (ANSI standard) signaling processing sub-module, and then transferred to the CDMA service of the service processor The processing sub-module performs user authentication and short message analysis. If the destination address of this message is a GSM mobile phone, then the CDMA service processing submodule first carries out message format conversion, and then the message is forwarded to the GSM service processing submodule, and the GSM service processing submodule is responsible for delivery to the GSM mobile phone; if the message's The destination address is still a CDMA mobile phone, then the CDMA service processing submodule sends the short message to the CDMA MAP signaling processing submodule, and this module is responsible for finding routing and forwarding the short message. The signaling message for routing is sent to the destination user HLR (CDMA network) located in the No. 7 signaling network through the TCAP (ANSI standard) signaling processing submodule, SCCP signaling processing submodule, and MTP signaling processing submodule, and forwarded The signaling message of the short message is also sent to the visiting MSC or home short message of the destination user located in the No. 7 signaling network through the TCAP (ANSI standard) signaling processing submodule, the SCCP signaling processing submodule, and the MTP signaling processing submodule Center (CDMA network).

Since the encapsulation format of GSM and CDMA short messages and the arrangement of message parameters are different, when converting a GSM short message into a CDMA short message, it is necessary to first decode the short message according to the format defined by the GSM short message (GSM03.40 standard). The parameters of each part, including the content of the short message actually transmitted, are then correspondingly filled into the format of the CDMA short message (IS-637 standard). During the conversion process, some parameters cannot be completely corresponded, including the The content of CDMA is not defined in CDMA, and the content of CDMA short message structure is not defined in GSM. During the format conversion process, the parameters that do not exist can be added according to the system default configuration or user requirements. For redundant parameters It can be ignored or recorded in the short message database. A similar processing method can also be adopted when converting a CDMA short message into a GSM short message.

At present, the short message service has become a recognized important business growth point, and the telecom operators are making great efforts to build a short message center in a wider range to provide users with a variety of value-added services based on short messages, so as to attract users.

Because the short message center can also realize various value-added services by connecting with manual stations, automatic stations, voice mailboxes, information stations, etc. Therefore, adopting the unified short message center of the present invention can make the GSM network and the CDMA network share the short message entities such as the manual station, the automatic station, the voice mailbox, the information station, etc., and save costs.

As for the CDMA network that has just started construction, because the number of users in the initial stage of network construction is small, it is uneconomical to invest in building a short message center at this time. If the established GSM short message center can be used to serve the CDMA network, it can provide short message services for a small number of users of the CDMA network without much investment, and can realize short message intercommunication with GSM network users, thereby attracting other potential users to join , Conducive to the market development of CDMA network. This is very attractive to operators who have GSM network and narrowband CDMA network at the same time.
