1. , the mapping and the processing method of inside and outside, a kind of base station chain line are used for wireless access network and are connected based on setting up the AAL2 data between the base station of the mobile communication system of ATM transmission system and base station controller, comprising:

  • 1.1 the business that base station controller sends upper-layer protocol NBAP to the base station is set up request;

    1.2 the NBAP protocol entity in the base station is communicated by letter with the ALCAP controlled entity, with the related resource information notice ALCAP controlled entity that distributes, the ALCAP controlled entity distributes one, and process is corresponding and return to the NBAP protocol entity with a special identifier of himself ins and outs therewith;

    1.3 the NBAP protocol entity in the base station is defined as this special identifier with this processing procedure corresponding transmission channel bearing identification and notifies the corresponding service processing unit;

    1.4 the NBAP protocol entity in the base station is composed the ID to Binding with the value of this special identifier, and the business of receiving in 1.1 is set up in the response message of request message this Binding ID is returned to base station controller;

    1.5 the ALCAP agreement controlled entity of the ALCAP agreement controlled entity in the base station controller in the base station sends ALCAP link setup request message, wherein has the base station and returns to the Binding ID of base station controller and be about to the parameters such as CID that this AAL2 of sign of foundation is connected in previous step is rapid;

    1.6 ALCAP agreement controlled entity is the value of this Binding ID in the base station, promptly the value of the special identifier that ALCAP distributes in 1.2 and CID and related resource information notice are passed to the ATM processing unit;

    1.7 the base station returns to base station controller success link setup message;

    1.8 base station controller transmit traffic data in the AAL2 connection of building up is given the ATM processing unit in the base station;

    1.9 the ATM processing unit in the base station is mapped to corresponding special identifier value according to the CID that receives, and according to related resource information such as processing units data are passed to the corresponding service processing unit and handle, service processing board carries out business data processing according to this special identifier value corresponding transmission channel carrying.
