Problems solved by technology

[0005] Obviously, there are following defects in the implementation of this conference call: first, the master controller needs to input the numbers of the called parties one by one when initiating a call; It brings inconvenience to the operation of the controlling party, which limits the application of the conference call service to a large extent; secondly, every time the controlling party calls a called party, the current MSC of the controlling party will exchange information with the HLR once. When the number of called parties is large, the signaling traffic between MSC and HLR will increase, resulting in network congestion

Embodiment 1

[0045] figure 1 It is a schematic flow chart of implementing a conference call according to Embodiment 1 of the present invention. In this embodiment, it is assumed that the guide number LN1 contains three conference members, one of which is a fixed phone with a phone number of CC-DN1, and the other two are mobile stations belonging to the same HLR and currently served by the same MSC, whose numbers are MIN1 and MIN2 respectively. see figure 1 , this embodiment specifically includes the following steps:

[0046] Step 101: The controlling party presets the pilot number LN1 corresponding to the conference member number and saves LN1 on the HLR related to the controlling party. If the master controller is a mobile phone, the HLR related to the master controller is the HLR that saves the data of the master controller; if the master controller is a fixed phone, the HLR related to the master controller is stored for the conference call service HLR selected for conference call in...

Embodiment 2

[0067] figure 2 It is a flow chart of implementing a conference call according to Embodiment 2 of the present invention. In this embodiment, it is still assumed that a guide number contains three conference members, one of which is a fixed phone with the phone number CC-DN1, and the other two are mobile stations MS1 belonging to the same HLR and currently served by the same MSC and MS2, the numbers are MIN1 and MIN2 respectively. see figure 2 , this embodiment specifically includes the following steps:

[0068] Steps 201 to 203 are the same as Steps 101 to 103 in Embodiment 1, and will not be repeated here.

[0069] Step 204: The HLR judges whether the originating MSC is capable of supporting a conference call according to the received TRANSCAP parameter, and if so, executes Step 205; otherwise, rejects the call and exits the procedure.

[0070] Step 205: The HLR retrieves the numbers of all members in LN1 saved by itself, and then sends a location response (locreq) mess...

Abstract

The present invention discloses realizing conference telephone method. Said method includes configuring leading number having conference member terminal number; originating mobile switching center MSC receiving conference originating side originated called number as leading number of originating, resolving said leading number, obtaining routing information of conference member terminal number in said leading number, then according to acquired routing information calling conference member terminal. Said invention has advantages of avoiding conference originated side one by one inputting all conference member terminal number, simplifying conference originated side operation. Furthermore, in one preferred embodiment, HLR sends together the all conference member terminal number routing information to originating MSC, therefore without many times signaling interaction between originating MSC and HLR, reducing signaling flow rate between MSC and HLR.

Description

technical field [0001] The invention relates to network voice communication technology, in particular to a method for realizing a conference call. Background technique [0002] The conference call (CC, Conference Calling) service is a voice communication service, which is mainly used for three or more users to talk at the same time. One user initiates a call connection to other multiple users, and the calling user is called a conference initiation party, the called user is called a conference member. Once the connection is established, if any conference member disconnects, it will not affect other users participating in the conference, and other users can continue to talk; if the conference initiator disconnects, the connections of other conference users will also be disconnected. calls are released. [0003] After the system provides the conference call service to the user, the user can hold a conference call as the conference initiator at any time to call multiple users ...
