Problems solved by technology

Since E1 has 30 time slots that can be occupied, there are many combinations of which time slots are occupied by 3G and 2G equipment, so the efficiency of exhaustive enumeration is very low

Embodiment Construction

[0052] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0053] As shown in Figure 2, the present invention firstly merges the transmission time slots of the 3G network and the transmission time slots of the 2G network, and then detects the time slots used between the base station controller (RNC) and the base station (Node B). For the heard time slot, the Node B adopts a bootstrapping protocol (BOOTP) to establish an IPOA-based maintenance channel.

[0054] As shown in Figure 3, the present invention needs to configure an external time slot crossover device (DACS) in the uplink direction of the 2G network base station (BTS) and the 3G network base station (Node B), and the external time slot crossover device connects the 2G The E1 / T1 time slot of the network and the E1 / T1 time slot of the 3G network are merged into one E1 / T1, so that the 3G network and the 2G network share the E1 / T1 transmission time slot. The ex...

Abstract

The invention for use in building a maintenance channel based on IPOA when a transmission is shared by 2G and 3G network and solving the problem that is the configuration state of lower link can not be effectively detected in a transmission shared by 3G and 2G networks so that the maintenance channel based on IPOA can not be automatically built. The method includes: makes crossing combination for the 3G transmission time slot and the 2D transmission time slot; and then listens to the time slot used between the RNC and Node B in term of the time slot combination; based on the listened time slot, Node B builds the maintenance channel based on IPOA by using BOOTP.

Description

technical field [0001] The invention relates to a transmission channel of a wireless network, in particular to a method for establishing a maintenance channel. Background technique [0002] With the development of wireless communication technology, the communication network is becoming more and more complex and large, which puts forward higher requirements for the maintainability of the network. 3G (3rd Generation Mobile Communication, third generation mobile communication) network in wideband code division multiple access (WCDMA), code division multiple access 2000 (CDMA2000), time division multiplexing synchronous code division multiple access (TD-SCDMA) communication system The agreement stipulates that the maintenance channel between the radio network controller (RNC) and the base station (Node B) adopts the form of IPOA (IP over ATM, IP on ATM), but does not define the establishment method of the maintenance channel between the RNC and Node B . [0003] In order to au...
