Message processing method, access control device and network system

Abstract

The invention provides a message processing method, accessing control equipment and a network system. The message processing method comprises the steps that through an MP group interface, the accessing control equipment receives point-to-point protocol (PPP) sharding messages which are sent by network cell equipment through an MP set, wherein the MP set comprises a plurality of PPP links; and the accessing control equipment puts the PPP sharding messages in a PW message in an encapsulation mode and sends the PW message to an opposite terminal accessing control equipment through one way of PW. According to the message processing method, the accessing control equipment and the network system, the sharding messages sent by the plurality of PPP links in the MP set and received by the accessing control equipment are sent by the way of PW, due to the fact that the received sharding messages are sent by the way of PW, the fact that the delay inequality that each sharding message sent by the network cell equipment arrives at the opposite terminal accessing control equipment is small is ensured, the success rate of restructuring the received sharding messages conducted by a base station controller is improved, and the reliability of data transmission is further greatly improved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a message processing method, access control equipment, and a network system. Background technique [0002] Synchronous Digital Hierarchy (abbreviation: SDH) network is no longer expanding or the maintenance cost is too high, or has reached the end of life cycle, but operators still have a large number of E1 interfaces and point-to-point protocol (Point-to-Point Protocol; abbreviation: PPP) services need to continue to be carried. By creating a new AccessTransportNetwork (AccessTransportNetwork; ATN for short) network, the replacement of the existing SDH network can be realized. [0003] figure 1 It is a schematic diagram of sending a PPP message through a pseudowire (Pseudowire, PW for short) established by a circuit emulation service (CES for short) interface in the prior art, as shown in figure 1 As shown, the interface on the base station 11 side is a ...

Problems solved by technology

[0004] However, due to the inconsistent jitter and buffering on different PWs, the delay difference between the fragmented messages sent on each PW will be very large, and the packet reassembly delay difference that the base station controller 14 can tolerate is very small , so when there are many PWs, the base station controller 14 may fail to reassemble the received fragmented message, resulting in the discarding of the fragmented message
