Message processing method and device

Abstract

The invention provides a message processing method and a device. The message processing method comprises the following steps that: a core network device receives and parses a SIP (Session Initiation Protocol) signaling transmitted by other devices of the core network, converts the signaling into a TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) signaling according to a signaling format conversion rule between the SIP and the TD-SCDMA protocol, and transmits the converted signaling to an access network device; or the core network device receives a TD-SCDMA signaling transmitted by the access network device, converts the signaling into the SIP signaling according to the signaling format conversion rule between the SIP and the TD-SCDMA protocol, parses the signaling, and then transmits the signaling to other devices of the core network. With the message processing method and the device of the invention, the SIP signaling and the TD-SCDMA signaling are used as the protocol interaction mechanism of a network side and a user terminal, and the times of TD-SCDMA air interface signaling transmission and the data volume of the signaling message both are reduced, thus, the transmission delay is reduced greatly, the system capacity is improved and the resource of air interface channels is saved.

Description

technical field [0001] The invention relates to a message processing method and equipment, in particular to a processing method and equipment for air interface channel message transmission in a time division synchronous code division multiple access system. Background technique [0002] In the third-generation communication standard, some communication systems use Session Initiation Protocol (SIP) as the communication protocol between the network side and the terminal client. Since the SIP protocol is based on text encoding, it has a flexible expansion mechanism and strong capabilities. The negotiation mechanism improves the flexibility and reliability of the system, and there are many tools for easy debugging. However, the SIP protocol used is based on the text encoding method. The amount of data contained in SIP signaling is relatively large. The content contained in large messages has several kilobytes of Bytes, and the content of small messages has dozens of Bytes; when ...

Problems solved by technology

[0004] In a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system, if two random access channels (Random Access Channel, RACH) or Forward Access Channel (Forward Access Channel, FACH) can transmit 144 bits of data when the transmission time interval TTI is 10ms. The transmission of SIP signaling will take a long time for transmission. In the cluster service, the transmission delay of the signaling is too long, which will greatly affect the establishment delay of the group service, the floor application / preemption delay and other indicators; if using Allocating more channel resources to reduce the transmission delay will waste precious air interface channel resources and affect the system capacity. Therefore, the SIP signaling is directly transmitted, and the SIP signaling is used as the protocol between the network side and the terminal client. Interaction mechanism, the performance index of group business will not be able to meet many application scenarios
