Description

A Method for Realizing Short Message Transfer

technical field

The invention relates to wireless communication technology, in particular to a method for realizing short message service in a mobile intelligent network.

Background technique

The mobile intelligent network is a network architecture that provides new services quickly, effectively, economically and conveniently in the mobile network. The service capabilities of the mobile intelligent network are closely related to its application protocols to a large extent. As early as 1997, the European Telecommunications Standardization Organization ETSI launched the CAMEL specification in order to solve the interconnection problem between the GSM mobile communication network and the intelligent network. The full name of CAMEL is Customized Applications for Mobile Network EnhancedLogic (Customized Applications for Mobile Network EnhancedLogic). The development of CAMEL specification has gone through CAMEL1, CAMEL2, CAMEL3 to the current CAMEL4 proposal draft.

The mobile intelligent network adds some network functional units to the existing mobile network, such as: service control point (SCP), service switching point (SSP), service management point (SMP), service management access part (SMAP), service generation environment ( SCE), service charging point (SDP), etc., separate the service control function from the traditional switching function, so that the network can flexibly and conveniently provide new services to meet the needs of users. It is the combination of existing mobile network and intelligent network.

The purpose of the mobile intelligent network is to enable telecom service operators to economically and effectively provide various new services required by users, to enable users to have stronger control functions on the network, and to obtain required services conveniently and flexibly.

The short message service can be provided for users based on the mobile intelligent network, and its process includes: the mobile switching center (MSC) receives the short message sent by the calling party to the called method, and forwards it to the short message center (SMMC); Data (such as the number segment and the service control point comparison table) are matched, and a specific service control point is selected to send an authentication request message; the service control point authenticates the calling party, and sends an authentication response message to the short message center; If the authentication passes, the short message center sends the short message to the called party.

With the increasing pace of modern life, the communication between people is also becoming more and more frequent. In some cases, it may be necessary to realize the transfer of short messages: for example, the mobile phone needs to be carried with you, but sometimes it is inevitable to forget to carry it; or due to insufficient power of the mobile phone or It cannot be used normally because it is not in the service area.

Please refer to Fig. 1, a kind of prior art that realizes short message service based on mobile intelligent network is disclosed in the Chinese invention patent application that the publication date is November 13, 2002, and the application number is 01111100, and its process includes: receiving end service switching point Submit the short message information to the service control point of the receiving end. If it belongs to the short message that needs to be transferred, the service control point starts the short message transfer service logic of the receiving end, returns the corresponding destination user number or the address of the short message center to the service exchange point, and Affect the processing flow of the service exchange point, and send the short message to the final mobile station, electronic mailbox or short message center.

The prior art can realize short message transfer, so as to enhance the function and flexibility of short message service. However, it has some deficiencies: First, it needs to carry out considerable transformation to the existing mobile network, which is costly and causes a waste of existing resources: due to the need Submit the short message information, and the service control point will start the message transfer business logic, which changes the processing flow of the existing short message service, and the service exchange point is generally set in the mobile switching center, so it is necessary to control the service control point, service exchange point, and mobile switching center. center and short message center; since the service control point returns the corresponding destination user number or short message center address to the service exchange point, it is necessary to modify the agreement between the service control point and the service exchange point, and the service control point and the service exchange The points are connected by the No. 7 signaling network, so the No. 7 signaling network needs to be expanded. Secondly, on the basis of the existing processing flow of the short message service, additional processing of short message transfer needs to be added at the receiving end, and the processing process is quite complicated.

In addition, based on the existing short message service implementation method, a possible method to realize the short message transfer service is: register the user's short message transfer data in the short message center, so that when the short message center receives the short message, the called The party converts the transferred number to address the called mobile phone. However, the disadvantage of the method is more serious: the processing capacity of the short message center is limited, and the data of the user setting transfer information on the intelligent network is backed up to the short message center, it is difficult to avoid data inconsistency and the maintenance of the data is relatively inconvenient.

Contents of the invention

The technical problem solved by the invention is to provide a method for realizing short message transfer with lower cost and simpler processing.

For this reason, the technical scheme that the present invention solves technical problem is: provide a kind of method that realizes short message transfer, be applied to the mobile intelligent network that comprises short message center and service control point, comprise steps:

1) The short message center receives the short message sent by the first mobile terminal to the second mobile terminal;

2) The short message center sends an authentication request message to the service control point;

3) The service control point starts the short message transfer service logic, and sends an authentication response message including the third mobile terminal number to the short message center;

4) The short message center sends the short message to the third mobile terminal according to the authentication response message.

Compared with the prior art, the beneficial effects of the present invention are: first, because the present invention is realized on the basis of the existing short message service of the mobile intelligent network, the transformation that needs to be carried out to the network is smaller than the prior art, and costs can be saved: only It is necessary to modify the short message center and the service control point, and expand the SMPP protocol between the short message center and the service control point, so that the authentication process is started by the short message center, and the short message is activated when the service control point performs calling and/or called authentication. The message transfer business logic uses the database data to determine whether the user has registered the transfer number, sends the authentication response message containing the number of the third mobile terminal to the short message center, and sends the short message to the third mobile terminal through the short message center to realize Short message transfer function. Secondly, the present invention only needs to start the short message forwarding service during authentication, and change the called number when issuing the authentication response message, and the processing process is simpler than the prior art.
