43、将把相关的信息通知MM。这一过程由终端发起，GPRS附着过程有三种类型：GPRS ATTACH ONLY ,IMSI 附着的GPRS附着,组合的GPRS附着.空闲方式下的PS附着过程，如是衔接方式下的附着过程，不需随机机接入过程，仅需初始直传/上下行直传过程。初始直传/上下行直传。ATTACH IE如下：value UL-DCCH-Message := message initialDirectTransfer : cn-DomainIdentity ps-domain阐明业务类型：CS域还是PS域, intraDomainNasNodeSelector version release : c
