Multiple service device and its signal processing method based on primary group

Abstract

The present invention discloses E1 / T1based multiple business equipment and signal processing method, to make same equipment capable of supporting variety E1 / T1 interface based service type, referring to E1 / T1 application technology. The present invention uniformly realizes service data link layer and application layer processing in service process module, wherein containing current technology single service process chip all function, and increasing interface adaptive logic used for uniformly adapting multiple operation multiple operation to E1 / T1 frame chip physical layer interface to service process module physical layer interface. Service process module correlation processing function can be realized in hard ware mode by ASIC chip, also in software mode by CPU, NP, DSP etc processor. Interface adaptive logic also can added in physical layer with time slot crossing, time slot merging, inserting random error, and replacing assigned content etc processing.

Description

technical field [0001] The invention relates to the application technology of E1 / T1, in particular to the E1 / T1-based multi-service equipment and its signal processing method. Background technique [0002] The mobile communication network can meet people's requirements for communication anytime and anywhere, so it has developed rapidly. With the development of mobile communication technology, simple calls can no longer meet the requirements of users, and the mobile communication network will be upgraded from the second generation of mobile communication (The Second Generation, referred to as "2G") to the third generation of mobile communication (The Third Generation, referred to as "3G"). [0003] In terms of functions, the communication network can be roughly divided into a core network (Core Network, “CN” for short) and a radio access network (Radio Access Network, “RAN” for short). CN mainly handles all voice calls and data connections in the network and implements swit...

Problems solved by technology

[0015] In actual application, the above solution has the following problems: complex hardware design, high cost, limited service types based on E1 / T1 interfaces supported on the same device, poor service scalability, and low device utilization

[0016] The main reason for this situation is that different types of services need to be realized by using service processing boards corresponding to each service, so the hardware architecture is complicated, and its design cost and hardware cost are high.

[0017] Because the expansion of the business needs to increase the business single board, which involves the hardware expansion of the equipment, the expansion of the equipment space, the expansion of the circuit board, etc., so in the case of limited equipment capacity, the types of services that can be supported are limited and the business expansion is poor.

[0018] For test equipment, only one E1 / T1-based service is used at the same time, so the unused service processing chips are idle, which makes the utilization rate of the equipment low
