1. the mapping and the processing method of inside and outside, 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, it is characterized in that described method comprises:

  • 1.1 the business that base station controller sends high-rise NBAP agreement 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, one of ALCAP controlled entity distribution is set up a corresponding chain line of request process with business and is returned to the NBAP protocol entity, wherein, described chain line is the sequence number that the ALCAP controlled entity is handled subprocess, promptly handle instance number, this instance number is to handling subprocess relevant resource and data by the ALCAP controlled entity;

    1.3 the NBAP protocol entity in the base station is defined as this chain line with business and sets up request process corresponding transmission channel bearing identification and notify 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 chain line, 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 controlled entity of the ALCAP 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 BindingID of base station controller and be about to the CID parameter that this AAL2 of sign of foundation is connected in previous step is rapid;

    1.6 the ALCAP controlled entity is the value of this Binding ID in the base station, promptly the value of the chain line that ALCAP distributes in 1.2 and CID and related resource information send the ATM processing unit to;

    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 the link corresponding ident value according to the CID that receives, and according to the related resource information that the ATM processing unit is received business datum is passed to the corresponding service processing unit and handle, Service Processing Unit carries out business data processing according to this link ident value corresponding transmission channel carrying.
