Abstract

The present invention discloses a method and a system for implementing location service, in which the method comprises: sending a location request message from a source user to a MMSG by a MMSC; sending the location request message to a multimedia message generating platform by the MMSG; initiating a location request to an LSP by the multimedia message generating platform according to the location request message; performing location according to the initiated location request and returning a location result to the multimedia message generating platform by the LSP; generating multimedia message information according to the location result and sending the multimedia message information to the MMSG by the multimedia message generating platform; and sending the received multimedia message information to the source user through the MMSC by the MMSG. The present invention can not only reduce the requirement of the location service on terminal capability, but also more conveniently develop the location service, thereby realizing the aim of providing convenient and efficient location service to users by using multimedia message information.

Claims

1. A method for implementing location service, comprising:

sending a location request message from a source user to a Multimedia Messaging Service Gateway (MMSG) by a Multimedia Messaging Service Center (MMSC);

wherein the location request message comprises;

an identifier of the multimedia message generating platform, a position service identifier, an identifier of the source user, and an identifier of a target user which the source user requests to locate;

sending the location request message to a Data Service Management Platform (DSMP) by the MMSG;

processing the identifier of the source user and/or the identifier of the target user according to a predetermined processing and returning a processed identifier of the source user and/or a processed identifier of the target user to the MMSG by the DSMP;

sending the position service identifier and the processed identifier of the source user and/or the processed identifier of the target user to the multimedia message generating platform by the MMSG according to an identifier of the multimedia message generating platform;

initiating a location request to a Location Service Platform (LSP) by the multimedia message generating platform according to the position service identifier and the processed identifier of the source user and/or the processed identifier of the target user;

performing location according to the initiated location request and returning a location result to the multimedia message generating platform by the LSP;

generating multimedia message information according to the location result and sending the multimedia message information to the MMSG by the multimedia message generating platform;

sending the multimedia message information to the DSMP by the MMSG;

determining the identifier of the source user according to the processed identifier of the source user, replacing the processed identifier of the source user in the multimedia message information with the determined identifier of the source user by the DSMP, and sending the replaced multimedia message information to the MMSC; and

sending the replaced multimedia message information to the source user by the MMSC according to the identifier of the source user in the replaced multimedia message information.

2. The method according to claim 1, wherein the step of performing location by the LSP according to the initiated location request comprises:

inquiring the identifier of the source user and/or the identifier of the target user of the DSMP by the LSP according to the processed identifier of the source user and/or the processed identifier of the target user;

determining a service type of the location service by the LSP according to the position service identifier; and

locating the target user or locating both the source user and the target user by the LSP according to the inquired identifier of the source user, the inquired identifier of the target user and the determined service type, thereby obtaining location information.

3. The method according to claim 2, wherein the step of inquiring the identifier of the source user and the identifier of the target user of the DSMP by the LSP according to the processed identifier of the source user and/or the processed identifier of the target user comprises:

providing the identifier of the source user and the identifier of the target user by the DSMP according to an inverse transformation of the predetermined processing.

4. The method according to claim 2, wherein the step of performing location according to the initiated location request and sending the location result to the multimedia message generating platform by the LSP comprises:

sending the location result which consists of the location information, the processed identifier of the source user and/or the processed identifier of the target user to the multimedia message generating platform by the LSP.

5. The method according to claim 4, wherein the step of generating the multimedia message information according to the location result and sending the multimedia message information to the MMSG by the multimedia message generating platform comprises:

generating the multimedia message information according to the location information in the location result, and sending the processed identifier of the source user and/or the processed identifier of the target user to the MMSG through the generated multimedia message information by the multimedia message generating platform.

6. The method according to claim 1, wherein the processing the identifier of the source user and/or the identifier of the target user according to a predetermined processing comprises:

encrypting the identifier of the source user and/or the identifier of the target user according to a predetermined processing.

7. A method for implementing location service, comprising:

sending a location request message from a source user to a Multimedia Messaging Service Gateway (MMSG) by a Multimedia Messaging Service Center (MMSC);

wherein the location request message comprises;

an identifier of the multimedia message generating platform, a position service identifier, an identifier of the source user, and an identifier of a target user which the source user requests to locate;

sending the location request message to a Data Service Management Platform (DSMP) by the MMSG;

processing the identifier of the source user and/or the identifier of the target user according to a predetermined processing and returning a processed identifier of the source user and/or a processed identifier of the target user to the MMSG by the DSMP; and

sending the position service identifier and the processed identifier of the source user and/or the processed identifier of the target user to the multimedia message generating platform by the MMSG according to an identifier of the multimedia message generating platform;

initiating a location request to a Location Service Platform (LSP) by the multimedia message generating platform according to the position service identifier and the processed identifier of the source user and/or the processed identifier of the target user;

performing location according to the initiated location request and returning a location result to the multimedia message generating platform by the LSP;

generating multimedia message information according to the location result and sending the multimedia message information to the MMSG by the multimedia message generating platform;

sending the received multimedia message information to the source user through the MMSC by the MMSG.

8. A system for implementing location service, comprising:

a Multimedia Messaging Service Center (MMSC), a Multimedia Messaging Service Gateway (MMSG), a multimedia message generating platform, a Location Service Platform (LSP), and a Data Service Management Platform (DSMP), wherein

the MMSC is used for sending a location request message from a source user to the MMSG and sending the replaced multimedia message information from the MMSG to the source user;

wherein the location request message comprises;

an identifier of the multimedia message generating platform, a position service identifier, an identifier of the source user, and an identifier of a target user which the source user requests to locate;

the MMSG is used for sending the location request message from the MMSC to a Data Service Management Platform (DSMP); and

sending the position service identifier and the processed identifier of the source user and/or the processed identifier of the target user to the multimedia message generating platform according to an identifier of the multimedia message generating platform; and
