Method and device for realizing short message closed user group service

Abstract

The invention discloses a method for realizing a short message closed user group service, which comprises the following steps of: (1) when a response to a route query request sent by an external network short message center to a local network is returned back to the external network short message center, replacing a user terminal address in the response with the address with a storage; (2) when the external network short message center sends a short message to the storage, caching the short message; (3) judging whether the short message is allowed to issue according to the calling number and the called number of the short message and the requirements on the short message closed user group service of the local network; if yes, executing the step (4), or else executing the step (5); (4) issuing the short message to a destination user terminal; and (5) intercepting the short message. The method can be used for judging and controlling the closed user group service on short messages sent from an external network to the local network in the GSM / UMTS (Global System for Mobile Communications and Universal Mobile Telecommunications System) network. The invention also correspondingly discloses a device for realizing the short message closed user group service.

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...

Problems solved by technology

[0010] The technical problem to be solved by the present invention is to provide a method and device for realizing closed user group service of short message, so as to solve the problem that in the prior art, in the GSM / UMTS network, it is impossible to close the short message from the external network to the local network. Business judgment, so that it is impossible to intercept short messages that do not meet business requirements and defects
