Embodiment Construction

[0023] In the present invention, the interconnection between the DSN network and the softswitch network is realized by introducing a visitor location register-application server (VLR-AS).

[0024] image 3 It is a schematic diagram of a network architecture for realizing interconnection and intercommunication between a DSN network and a softswitch network in the present invention. Such as image 3 As shown, the VLR-AS is connected to the SN in the DSN network and the HLR in the softswitch network; the HLR stores the relevant information of all users, and the SN can access the HLR through the VLR-AS. For the DSN network, the VLR-AS It is an application server, but it has the function similar to the VLR in the softswitch network.

[0025] When a terminal in the DSN network updates its location, it needs to report the updated location information to the HLR through its SN and VLR-AS, ​​and accordingly, the HLR records the updated location information.

[0026] When a terminal ...

Abstract

The invention discloses a method and device for realizing interconnection between a DSN network and a softswitch network: a VLR‑AS is set in the DSN network, and the VLR‑AS is connected to the SN in the DSN network and the HLR in the softswitch network ; When terminal A in one network needs to communicate with terminal B in another network, VLR‑AS interacts with HLR and SN to provide the required information for both communication parties and assist them to complete the communication . The compatibility and usability of the network can be improved by applying the method and device described in the present invention.

Description

technical field [0001] The present invention relates to network technology, in particular to a method and device for realizing interconnection between a distributed service network (DSN, Distributed Service Network) and a softswitch network. Background technique [0002] The softswitch network is a packet-based network. The basic meaning of softswitch is to separate the call control function from the media gateway (transport layer), and realize the basic call control function through software, so as to realize the separation of call transmission and call control. [0003] figure 1 It is a schematic diagram of the control plane architecture of the existing R4 softswitch network. Such as figure 1 As shown, it mainly includes: Mobile Switching Center (MSC, Mobile Switching Center), Visitor Location Register (VLR, Visitor Location Register), Home Location Register (HLR, Home Location Register), Media Gateway Control Function entity (MGCF, Media Gateway Control Function ), med...
