Embodiment Construction

[0028] FIG. 1 is a block diagram showing a microwave frame adaptation device according to the present invention. As shown in Figure 1, the microwave frame adaptation device includes: a microwave frame construction module 102, used to construct a microwave frame that can carry low-order services without a high-order pointer; a microwave frame adaptation module 104, used to Microwave frames without high-order pointers are adapted to the STM-N / STS-N frame structure; and the frame positioning information position regeneration module 106 is used to regenerate the frame positioning information through the flag bits that have a fixed position relationship with the frame positioning information s position. Wherein, the microwave frame that can carry low-order services without high-order pointers can be a microwave frame extracted from SDH / SONET frame structure, or a reconstructed microwave frame. In the SDH / SONET frame structure, the position of the high-order pointer is fixed.

Abstract

The invention provides a microwave frame adaptation device and method. The method consists of step S402 which is that the microwave frame which can carry lower order service without high order pointer is structured by microwave frame structure module, step S404 which is that the microwave frame which can carry lower order service without high order pointer is adapted into STM-N / STS-N frame structure by microwave adaptation module, and step S406 which is that frame location information position regeneration module regenerates the position of the frame location information by flag bit which has fixed position relation with the frame location information. By using the invention, using less microwave frame overhead can be realized, and flexible operation of upload and download business of the network can also be realized.

Description

technical field [0001] The present invention relates to a communication device and method, in particular to a microwave frame adaptation device and method. Background technique [0002] At present, from the perspective of technology and network application, the optical fiber multi-service transport platform (Multi-Service Transport Platform, referred to as MSTP) has been very mature, but due to land privatization, and terrain restrictions, it is necessary to use it in many places Wireless transmission, when the bandwidth requirement is large and the transmission distance exceeds 1 km, microwave transmission is usually used. At present, in market applications such as base station backhaul transmission of mobile cellular systems, transmission network metropolitan area network, digital relay transmission network of radio and television, private network (such as electric power, public security, army, etc.), and large enterprise access, microwave Transmission has larger applicat...
