Embodiment Construction

[0050] The invention provides a method for performing multiplexing negotiation between network elements and service channels of the network elements by using RTCP messages. When the interface is in the IP environment, NE A and NE B can perform multiplexing negotiation through this multiplexing negotiation method. After the negotiation is completed, both parties decide whether to implement multiplexing and what kind of multiplexing to implement according to the negotiation result.

[0051] As long as the interface between the network elements is an IP environment, the RTCP intermittent transmission mode provided by the present invention can be used for multiplexing negotiation between service channels. The implementation examples of the present invention use BSC network elements and MGW network elements to describe and illustrate the RTCP discontinuous transmission mode. For any other network elements whose interface is IP environment and the multiplexing negotiation between the...

Abstract

The invention provides a multiplex consultation method and a system by using a real-time transmission control protocol (RTCP) message. The method comprises the following steps: when multiplex consultation is carried out between a net element and a peer net element which establishes a user surface with the net element, the net element sends an RTCP consultation message with a preset length only tothe peer net element which carries the multiplex information of the net element. The method can use less bandwidth to finish the multiplex consultation of a business channel between the net elements,avoid the defects caused by constantly sending the RTCP consultation message, and improve the effective use efficiency of the bandwidth.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to an environment where the interface between network elements is an IP (Internet Protocol, Internet Protocol), and the service channels of two network elements use RTCP (RTP (Real-time Transport) Protocol, real-time transport protocol) Control Protocol, real-time transport control protocol) The method and system adopted for the multiplexing negotiation carried out by the message. Background technique [0002] In the current GSM (Global System for Mobile Communications, Global Mobile Communications) system, the terminal MS (Mobile Station, mobile station) is connected to the BTS (Base TransceiverStation, base transceiver station) through the air interface, and the base station is connected to the BSC ( Base StationController, base station controller) connection, BSC and MGW (Media GateWay, media gateway) in MSC (Mobile services Switching Center, mobile switching center) c...
