Call connection method, system and device applied to virtual private mobile network

Abstract

The invention discloses a call connection method, system and device applied to a virtual private mobile network, which simplifies the call connection flow in the prior art VPMN and greatly reduces the call delay. It is worth noting that although this method simplifies the call connection process in the prior art, the simplified call connection process can still ensure the technical effect of successfully realizing the call connection under the premise of charging the call.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a call connection method, system and device applied to a virtual private mobile network. Background technique

[0002] Virtual private mobile network (Virtual Private Mobile Network, VPMN), commonly known as "group network", "local area network", "company network" or "micro network", etc., is to establish a logical private network on the public mobile communication network. VPMN is tailor-made for group customers and represents the interests of group customers. It is also a high-efficiency and low-cost intercom LAN service for group customers. When group customers use mobile phones for internal communication, it is as convenient as using their own private mobile communication network.

[0003] Specifically, VPMN can provide voice and video calls to internal members of the group customers, and can realize group services such as short number calls among internal members wit...

Examples

Embodiment 1

[0093] Embodiment 1 provides a call connection method applied to a virtual private mobile network, the method mainly includes the following steps:

[0094] First, after receiving the call initiated by the VMPN user, the first switching system sends the caller's real number and called number to the short number platform;

[0095] Then, the first switching system receives the connection indication message generated and sent by the short number platform according to the first calling number and called number;

[0096] Finally, when the connection indication message is a connect message, the first switching system determines the second switching system at the location of the called user according to the called real number contained in the connect message and sends the second switching system of the call to the second switching system. A call connection request; and the calling real number and the called real number are recorded in the calling bill of the call; wherein, the first c...

Embodiment 2

[0104] Embodiment 2 provides another call connection method applied to a virtual private mobile network, the method mainly includes the following steps:

[0105] First, the switching system receives the call connection request containing the calling real number and the called real number of the call initiated by the VMPN user sent by other switching systems;

[0106] Then, the call is connected, and the real number of the calling party and the real number of the called party included in the call connection request are recorded in the called bill of the call.

[0107] Optionally, the call connection request may also include a calling number that matches the caller ID mode agreed upon by the called user. Then, the method may further include the step: the switching system includes the call connection request in the The included calling number is sent to the user terminal using the called real number for display.

[0108] Embodiment 2 also provides a switching system, including t...

Embodiment 3

[0113] Embodiment 3 provides a message sending method, which mainly includes the following steps:

[0114] Step 1: The short number platform receives the calling number and the called number of the call initiated by the VMPN user sent by the switching system;

[0115] Step 2: According to the corresponding relationship between the pre-stored VPMN user number and the VPMN group identification to which the VPMN user number belongs, judge whether the calling real number and the called number sent by the switching system correspond to the identification of the same VPMN group; and in judging If the result is no, go to step 3; and if the result is yes, go to step 4;

[0116] Step 3: Send a continue message to the switching system;

[0117] Step 4: Determine whether there is a conversion to the calling number or the called number, and when it is determined that there is, send a connect message that includes the called real number to the switching system; when it is determined that ...
