Access method and apparatus for farend equipment of distributed communication system

Abstract

The invention provides an access method for a remote device in a distributed communication system and an access device thereof. The access method comprises the following steps: a local central device or a remote device in the access state transmits the main-control interface ID information via the main-control interface thereof; and a remote device in the state of waiting for the access configures the interface of the main-control interface ID information from the local central device to a controlled interface, and transmits an access request to the local central device via the controlled interface to establish the connection with the local central device. The access method and the access device can achieve the effects of self-adapting access and topological identification of the remote device.

Description

technical field [0001] The present invention relates to the technical field of equipment management in a distributed communication system, in particular to a method for accessing remote equipment in a distributed communication system, a local central equipment and remote equipment. Background technique [0002] In some distributed communication systems, due to the requirements of the system structure, the communication system network consists of a local central equipment (LCE, Local Central Equipment) and several remote equipment (RE, Remote Equipment). The RE is controlled by the LCE. Before the RE can work normally, it needs to first establish a connection with the LCE, including the connection of control signaling and service data transmission channels. The process of establishing a direct or indirect connection between the RE and the LCE is called the RE access process. [0003] The interface (IF, Interface) of RE and LCE can be directly or indirectly connected through ...

Problems solved by technology

[0009] 1. Apply the upper-layer software to configure the master-slave characteristics of the IF. The software needs to monitor and configure the underlying hardware and physical signals. There are too many control links and the process is complicated;

[0010] 2. During the access process, it is necessary to switch frequently between various IFs, which is likely to cause an endless loop, and the switching cycle may be a different time value for various systems, which increases the burden on the development and maintenance of various systems;

[0011] 3. For different distributed communication networks, the time delays for RE upper-layer software to send access requests to LCE or upper-level RE responses are different, which adds difficulties to the implementation of upper-layer software;

[0012] 4. The existing method must pre-set the network topology before the network is established, and cannot automatically complete topology identification by software and hardware
