Problems solved by technology

However, the existing protocol does not describe the parameter conversion when BICC and SIP use CMN interworking, and how to carry UP information in SIP, resulting in the inability to communicate between BICC and SIP

Embodiment Construction

[0038] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0039] The basic CMN networking model used in the embodiment of the present invention is as follows figure 2shown. Among them, the CMN is located between the BICC and the SIP, the Nc interface on one side transmits the BICC signaling, the Nc interface on the other side transmits the SIP signaling, and the Nb interface on the user plane directly communicates with the two MGWs. It can be seen from the figure that after CMN signaling conversion, one side of the Nb interface is controlled by the SIP protocol, and the Mc interface is described by SDP; while the other side is controlled by the BICC protocol, and the Mc interface is described by IPBCP. The conversion between IPBCP and SDP in the prior art basically solves the problem of media negotiation between different control protocols, but does not describe how to carry UP inf...

Abstract

The invention provides a method for communication between a bearer independent call control protocol BICC and a session initiation protocol SIP, which comprises the following steps: a call media node CMN carries out interconversion to a BICC signal and an SIP signal used by alternating a forward station and a backward station and expands the SIP signal obtained from the interconversion; and the information of a user plane UP is carried in the SIP signal. The embodiment of the invention further provides a device for the communication between the BICC and the SIP. By using the embodiment of the invention and through the interconversion between the BICC signal and the SIP signal as well as the information of the user plane UP carried in the SIP signal, the media negotiation between the BICC and the SIP is achieved, and the problem of the network communication between the BICC and the SIP is solved.

Description

Technical field [0001] The invention involves the field of communications technology, especially a BICC (Bearer Independent CallControl Protocol, carrying irrelevant call control protocols) and SIP (Session Initiation Protocol, session initialization protocol). Background technique [0002] With the development of the communications industry, the continuous evolution of various network protocols has promoted the increasing progress of communication technology.The third -generation mobile communication network represented by WCDMA (WideBand Code Division Multiple Access) is dedicated to providing a more convenient application business service environment. [0003] The core network of WCDMA adopts the R4 network architecture of network call control and business loading.Three interfaces are defined under the R4 architecture: NC interface, NB interface and MC interface, and the positions of each interface in the network are figure 1 Show.The network architecture includes MGW (Media G...
