Embodiment Construction

[0049] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] figure 1 It is a schematic diagram of the method flow chart of the implementation example of the present invention. As shown in the figure, the implementation method of the short message closed user group service of the present invention specifically includes the following steps:

[0051] 1. After receiving the routing query request from the SMS center of the external network, initiate a routing query request to the home location register of the destination user;

[0052] 2, after receiving the routing query response of the target user's home location register, replace the target user terminal address in the routing query response (the address of the mobile switching center MSC where the target user is located) with the address of a newly added memory of the present invention , and then return the routing query response to the...

Abstract

A method and device for implementing short message closed user group service are provided by the present invention, in which the method includes: the home network buffers the received short message transmitted from an outside network; based on the numbers of the caller and the called party of the cached short message, and the requirement of the short message closed user group service of the home network, whether said short message is allowed to be sent down is determined. The method of the present invention realizes determination and control of the closed user group service for the short message transmitted from the outside network to the home network in the Global System for Mobile Communication (GSM) / Universal Mobile Telecommunication System (UMTS) network, and enables the short message closed user group to achieve the integrated closed communication effect, thus meeting the service requirement completely.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a method and a device for realizing a short message closed user group service. Background technique [0002] The closed user group service is generated for some confidential group communication needs, and its basic requirement is that users in the group can communicate with other users in the group, but cannot communicate with users outside the group. Specifically, the requirement of the short message closed user group service is to release or intercept any short message originating from or terminating to the local network according to the following requirements: [0003] 1. If the caller is in the closed user group and the called party is not, intercept it; [0004] 2. If the caller is not in the closed user group, but the called party is, intercept it; [0005] 3. If both the calling party and the called party are in the closed user group, the call wi...
