Embodiment 1

[0032] figure 1 It is a flowchart of a multi-VPMN user call control method according to an embodiment of the present invention. Such as figure 1 As shown, this embodiment includes:

[0033] Step S102: after the first service control point receives the call request, when the VPMN service corresponding to the call request is not the service managed by the first service control point, judge the VPMN service corresponding to the call request according to the called short number corresponding to the call request;

[0034] Step S104: adding a predefined prefix corresponding to the VPMN service before the called short number;

[0035] Step S106: Send a call connection message, which includes a predefined prefix and a called short number.

[0036]Each VPMN service has its own independent numbering plan. The short number of the same user in different VPMN services can be independently defined by each VPMN service control point. For example, the number range of service 1 is 1001, 100...

Embodiment 2

[0041] figure 2 It is a flowchart of a multi-VPMN user call control method according to Embodiment 2 of the present invention. Such as figure 2 As shown, this embodiment includes:

[0042] Step S202: After receiving the call request, the MSC connects the call to the first SCP according to the preset subscription message;

[0043] Step S204: the first SCP receives the call request;

[0044] Step S206: Determine whether the VPMN service corresponding to the call request is a service managed by the first SCP, if yes, perform step S208; otherwise, perform step S210;

[0045] Step S208: the first SCP performs subsequent business logic processing on the call, and the process ends;

[0046] Step S210: the first SCP judges the VPMN service according to the called short number, and adds a predefined prefix corresponding to the VPMN service before the called short number;

[0047] Step S212: Send a call connection message to the MSC, the call connection message includes a predefi...

Embodiment 3

[0054] Both the multi-VPMN user call control methods in Embodiment 1 and Embodiment 2 can be applied to the calling side or the called side. In this embodiment, on the basis of the foregoing embodiments, the processing flow of the calling side / called side is further refined. image 3 It is a flow chart of the third multi-VPMN user call control method in the embodiment of the present invention. This example includes:

[0055] Step S302: Multiple VPMN users send call requests to the MSC on the calling side;

[0056] Step S304: The MSC on the calling side obtains the preset VPMN calling subscription information from the HLR on the calling side, determines the first SCP on the calling side, and connects the call to the first SCP on the calling side;

[0057] Step S306: After receiving the call request, the first SCP on the calling side judges whether the VPMN service is a service managed by itself, if so, execute step S308; otherwise, execute step S312;

[0058] Step S308: Perf...

Abstract

The invention discloses a multi-VPMN (Virtual Private Mobile Network) call control method, a service control point and a system. The multi-VPMN call control method comprises the following steps of: judging VPMN service according to a called short number after a first service control point receives a call request when the VPMN service corresponding to the call request is not service managed by thefirst service control point; adding a predefined prefix corresponding to the VPMN service in the front of the called short number; and sending a call proceeding message which comprises the predefinedprefix and the called short number. The multi-VPMN call control method, the service control point and the system solve the problem of call transfer among all VPMN systems by adopting a special prefixsecondary triggering method, can effectively ensure that different VPMN services are independent and improve the user experiences.

Description

technical field [0001] The invention relates to the field of intelligent network business in the communication technology, in particular to a multi-VPMN call control method, a service control point and a system. Background technique [0002] Virtual private mobile network (Virtual Private Mobile Network, referred to as VPMN) is a logical channel private network, which enables enterprises and group users to communicate with each other through abbreviated dialing and special numbering plans. The VPMN service allows VPMN users to make intra-network calls, off-network calls, and special numbers, which not only brings practical convenience and benefits to users, but also expands services for operators and improves industry competitiveness. [0003] There are two ways to trigger VPMN services: special prefix trigger and subscription information trigger. The special prefix trigger requires the user to add a special prefix before the number dialed, such as 12590. The triggering of...
