Radio local loop network, radio controller, exchanger and radio switch-in method

Abstract

A local loop network is prepared as arranging access module on radio control unit, using access module to receive logon information reported from terminal and to send request message of port through exchange digital user interface, using exchange to receive port request message sent from access module and to distribute exchange digital user port for terminal, using radio control unit to distribute exchange digital user port to said access module and using distributed port of access module as communication port between said terminal and exchange.

Description

technical field [0001] The invention relates to communication technology, in particular to a wireless local loop network, a wireless control device, a switch and a wireless access method. Background technique [0002] Wireless local loop (Wireless Local Loop, WLL) network is to use wireless technology to provide terminal business services for fixed terminal equipment or regional mobile terminal equipment. It has the advantages of strong ability, not easy to be damaged by natural disasters, and simple network configuration. The WLL network can be used as a supplement to the wired network, providing more abundant and economical network construction solutions for fixed network operators. [0003] Referring to FIG. 1 , it is a diagram of a WLL network architecture in the prior art. The WLL network includes a local exchange (LE) 110, a radio access controller 120 (Radio Access Controller, RAC) connected to the LE 110, and multiple base transceiver stations (Base Transceiver Sta...

Problems solved by technology

Therefore, the prior art causes the RAC 120 to process a lot of signaling across modules, reducing the processing capability of the entire RAC 120

[0009] 2. Cross-module calls will occupy a large amount of inter-module transmission bandwidth;

[0010] For the same reason as above, since the access modules accessed by terminals 140a, 140b, 140c, and 140d are often not access modules configured with user port information, business signals or data such as calls need to be processed across modules, which occupies a large amount of inter-module transmission bandwidth and reduces The processing power of the entire RAC 120

[0011] 3. High cost of use and management

[0012] In the prior art, the user V5 interface information is fixedly allocated or configured manually when opening an account. However, since the location of the wireless terminal in the WLL network is uncertain, it is not possible to determine in advance which V5 interface to assign the user port to when opening an account. The method is not easy to operate in engineering implementation; in addition, the wireless network will be adjusted frequently, resulting in frequent changes in the access locations of the terminals 140a, 140b, 140c, and 140d. higher cost
