Abstract

The invention discloses a method and a system for realizing base station cascade and a cascade processing logic subsystem. Two sides of a superior base station are connected with a base station controller and subordinate substations by different media; the superior base station and the base station controller are connected by an E1/T1 circuit; the superior base station and subordinate base stations are connected by Ethernet; and the cascade processing logic subsystem is used for realizing functions of flow control and congestion scheduling. The base station cascade mode of the invention realizes the dynamic sharing of bandwidth, reduces cost, improves networking flexibility and improves capacity of the cascaded base stations.

Description

Technical field [0001] The present invention relates to base station connection technology in the field of mobile communication, and in particular to a method, system and cascade processing logic subsystem for realizing base station cascading through different transmission media. Background technique [0002] At present, in the field of communications, there are multiple transmission media in network transmission, such as E1, T1, and Ethernet. Traditional E1 / T1 lines are mostly used in existing network transmission. Among them, E1 is a European standard with a rate of 2.048Mbps; T1 is a North American standard with a rate of 1.544Mbps. [0003] In the mobile network, the connection between the base station and the base station controller (BSC, Base Station Controller) adopts the E1 / T1 line transmission mode. In order to make full use of bandwidth resources, usually, multiple lower base stations are connected in base station cascade, that is, under each base station connected to t...

Problems solved by technology

With this connection method, the respective bandwidths of all lower-level base stations are exclusive, and the sum of the bandwidth of each lower-level base station is the bandwidth provided by the upper-level E1 / T1. The bandwidth provided by E1 / T1 is allocated to the lower-level base stations through the method of time slot separation. The bandwidth occupied by a lower-level base station is fixed and exclusive. Even when it does not use bandwidth resources, other lower-level base stations cannot use it, resulting in a waste of bandwidth resources.

In addition, if you need to access multiple lower-level base stations through the upper-level base station, you must configure multiple ports, resulting in a lack of flexibility in networking
