Method, system and apparatus for sending request bearing establishment completion indication

Abstract

The invention discloses a method, a system and a device for sending bear-requesting establishment-completing instructions, wherein the method comprises the steps of receiving a call control BICC protocol message which carries a bear-requesting establishment-completing instruction and is unrelated to bearing, acquiring the carried bear-requesting establishment-completing instruction, constructing and sending a session initiation protocol (SIP) encapsulation integrated service digital network (ISDN) user-part SIP-I protocol message which carries the bear-requesting establishment-completing instruction. The method, the system and the device which are provided by the embodiment of the invention can adopt an SIP-I protocol to send the bear-requesting establishment-completing instruction.

Description

technical field [0001] The invention relates to bearer establishment technology in a communication system, and in particular to a method, system and device for sending a request bearer establishment completion indication. Background technique [0002] The core network of Wideband Code Division Multiple Access (WCDMA, Wide Code Division Multiple Access) system defines three interfaces under the R4 architecture: Nc interface, Nb interface and Mc interface. The positions of each interface in the core network of WCDMA system are as follows: figure 1 shown. figure 1 It is a structural diagram of the core network of the prior art WCDMA system under the R4 architecture, including a gateway MSC Server (GMSC Server), a media gateway (MGW, Media Gateway) and a home location register (HLR, Home Location Register). Among them, GMSC Server can manage multiple MSC Servers. MSC Server and GMSC Server interact with HLR respectively to obtain the location information of UE. MSC Server provi...

Problems solved by technology

[0020] In the process of intercommunication between SIP-I protocol message and BICC protocol message and in the core network of CMN, how to realize the request bearer establishment completion indication? When the GMSC Server of the backward office uses the BICC protocol message to send the request bearer establishment completion indication, it does not know that the GMSC Server of the forward office uses the SIP-I protocol message for information exchange and needs to go through the CMN. At this time, the inventor, after studying the prior art It is found that the CMN needs to process the request bearer establishment completion indication carried by the BICC protocol message, and convert it into a SIP-I protocol message for transmission. However, the current SIP-I protocol message cannot carry the request bearer establishment completion indication, and in SIP-I The I protocol also does not describe how to carry the request bearer establishment completion indication in the SIP-I message

Furthermore, the current SIP-I protocol message cannot carry the bearer establishment completion indication, and there is no description in the SIP-I protocol of how to carry the bearer establishment completion indication in the SIP-I message

In this way, the backward office GMSC Server will not be able to obtain the bearer establishment completion indication
