Problems solved by technology

[0008] First of all, when the service transmission bearer protocol of the above existing technology is changed, the entire service interface processing board needs to be redeveloped and replaced. Since the physical interface module 10 and the transmission protocol processing module 11 are integrated on one single board, the interface design is complicated. It is time-consuming and labor-intensive to develop and implement a new business interface processing board, which cannot meet the market's demand for business interface board diversity and development speed, and the business interface processing board has low adaptability;
[0009] Secondly, the above-mentioned existing technology uses software combined with hardware to realize the corresponding functions including the physical interface module and the transmission protocol processing module, and the reliability is low

Embodiment Construction

[0040] The present invention mainly separates the processing of the transmission and bearer protocol from the processing of the physical interface, and adopts different single-board processing respectively, wherein the processing of the physical interface can be realized by pure hardware, and the processing of the transmission and bearer protocol can be realized by a programmable device programmed by software. To simplify the interface design and improve the reliability of the interface.

[0041] refer to image 3 , which is a schematic diagram of the composition of the service interface processing device of the present invention.

[0042] In the present invention, the physical interface processing device is divided into two independent single boards, that is, the physical interface board 20 and the transmission protocol processing board 21, wherein the physical interface board 20 is used to process the business data transmitted between the communication equipment and the exte...

Abstract

The invention discloses a treatment device for business interface, which comprises: a physical interface board to treat the business data between communication device and external network, and a transmission protocol treatment board connected to former board by a back board to treat the business data treated by former board according to its transmission protocol and obtain need business data or package the business data to be transmitted according to its transmission protocol to transmit to external network by former board. This invention just needs to exploit again the opposite software when protocol changes to meet market request for diversity and exploit speed.

Description

technical field [0001] The present invention relates to the technical field of service transmission, and more specifically, the present invention relates to a service interface processing device and method in communication equipment. Background technique [0002] Usually, the services transmitted in the communication network are based on a certain transmission protocol. Asynchronous Transfer Mode (ATM, Asynchronous Transfer Mode) transmission protocol, IP transmission protocol, etc. are widely used in various networks to transmit various services, such as in broadband In the code division multiple access WCDMA system, the AAL2 and AAL5 protocols of ATM are usually used to bear voice, data, control and other services. [0003] But on the other hand, due to the simple and flexible transmission of internal services in communication equipment, private bearer protocols are often used for service transmission inside communication equipment. Therefore, it is necessary to convert ex...
