Description

Method and device for implementing short message closed user group service

The invention belongs to the field of mobile communication technologies, and in particular relates to a method and a device for implementing a short message closed user group service. Background technique

The closed subscriber group service is generated for certain confidentiality group communication needs. The basic requirements for closed user group services are: Users in a group can communicate with each other, but users in a group cannot communicate with users outside the group. Specifically, the requirement for the SMS to close the user group service is for any short message that is called on the local network or terminated to the local network, and is released or pulled according to the following requirements:

1. If the caller is in the closed user group and the called party is absent, the interception is performed;

2. If the caller is not in the closed user group and is called, intercept it;

3. If the calling party and the called party are both in the closed user group, release the line;

4. If the calling party and the called party are not in the closed user group, they can be released or intercepted according to the operator's requirements.

At present, the current network closes the user group service for SMS, which is generally implemented based on the SMS center of the network. One way is to implement the closed user group function directly in the SMS center of the network: First, set the closed user group number in the short message center, and then judge the main called number and message interception of the flowing message; another way Yes, the construction of a dedicated filtering platform is connected to all the SMS centers of the network through the value-added service interface. The SMS center of the network sends the message to be judged to the dedicated filtering platform, and the dedicated filtering platform determines the closed user group attribute of the calling and called numbers. The message that delivers the condition is sent back to the SMS center, otherwise the message is intercepted.

In the above two existing methods, since the data is from the SMS center of the network, therefore, only Control the messages passing through the SMS center of this website. In the GSM (Global System for Mobile Communications)/Universal Mobile Telecommunications System (UMTS) network, the short message sent by the user to the local network is from the calling user. The SMS center of the network directly terminates the call to the mobile switching center where the destination user of the network is located, and then delivers it to the destination user terminal without going through the SMS center of the network.

It can be seen from the above description that in the GSM/UMTS network, if the short message closed user group service system implemented by the existing method is used, it is impossible to judge and intercept the short message that the external network terminates calling to the network. That is to say, the number in the closed user group of the network can receive any short message sent by the external network number, so that the closed subscriber group service requirement cannot be met.

Figure 7 shows the closed user group service judgment process, including the following steps:

Step 700: The closed user group service judgment module receives the short message cache module or the local network. SMSC's authentication request message.

Step 701: The closed user group service judging module first fetches the calling number in the message, and queries all the groups to which the number belongs and the sending and receiving relationship of each group.

Step 702: The closed user group service judging module secondly fetches the called number in the message, and queries all groups to which the number belongs and the group sending and receiving relationship.

Step 703: Comprehensively determine whether the calling number and the called party belong to the group, and the sending and receiving relationship between the groups, and determine whether the short message is allowed to be delivered.

Step 704: If the short message is allowed to be delivered, the success message is returned to the short message cache module or the SMSC of the local network.

Step 705: If the short message is not allowed to be delivered, a failure response is returned to the short message cache module or the local SMSC.

The short message of the local network is used to notify the closed user group service judgment unit whether to allow the delivery of the short message when there is a short message of the local network, and if the permission is sent, the short message is delivered to the destination user terminal, if not allowed, The short message is refused to be delivered to the destination user terminal.

By setting up the SMS center of the local network, the closed user group service control of the originating call message of the local network and the message of the external network to the local network is realized at the same time.

The SMS center of the network supports the access closed group service judgment unit by adding the authentication request construction module, the monitoring result processing module and the monitoring interface module, and realizes the closed user group service control of the originating short message of the local network.

The authentication request construction module is configured to construct an authentication request message, where the message carries the calling and called number of the originating short message of the local network, and the authentication request message is sent. The monitoring interface module sent to the short message center of the local network is sent by the monitoring interface module to the closed user group service determining unit to process the authentication request message.

The monitoring result processing module is configured to release or intercept the short message according to the authentication request response returned by the closed user group service determining unit.

The monitoring interface module is used to implement an external monitoring interface, and the business unit of the closed user group is determined. Send an authentication request message and receive a response message.

The processing flow of the SMS center supporting the SMS closed user group service includes:

(1) After receiving the message of the origin call of the local network, the short message center of the network does not send the message temporarily, and constructs an authentication request message through the authentication request building module, and sends the authentication request message to the monitoring interface module of the short message center of the network;

(2) The monitoring interface module of the short message center of the network sends an authentication request message to the closed user group service determining unit;

(3) The closed user group service judging unit takes out the calling and called number of the authentication request message, determines whether the short message meets the delivery condition, and returns a response to the monitoring interface module of the short message center of the network;

(4) The monitoring interface module of the short message center of the network forwards the judgment result of the closed user group business judgment module to the monitoring result processing module;

(5) The monitoring result processing module determines whether the message is delivered according to the judgment result. If the message is allowed to be delivered, the terminal call process is continued, and the short message is terminated to the MSC where the destination user is located; otherwise, the short message is intercepted.

The invention solves the problem that a message that cannot be terminated by the external network to the local network in the GSM/UMTS network is closed by adding a short message buffer unit, a short message closed user group service judging unit and a judgment result execution unit in the existing network. Group business control issues. By replacing the MSC address of the destination user service with the address of a memory, the short message that the external network terminates to the local network is sent through the memory of the short message cache module, thereby completing the closing of the short message of the external network to the local network. User group service judgment and message interception. Moreover, combined with the transformation of the short message center of the network, the SMS closed user group service control for all the originating call messages and the messages that are terminated to the local network are realized.

It is a matter of course that the invention may be embodied in various other forms and modifications without departing from the spirit and scope of the invention.
