SGSN abbr. GPRS业务支持节点(Service GPRS Supporting Node)
- If the SGSN receives no response from the MS to the Paging Request message, it shall repeat the paging.
如果SGSN没有在寻呼请求消息发送后从MS收到任何响应,它将重复进行寻呼。 - Therefore, any uplink data from the MS that moves the MM context at the SGSN to READY state is a valid response to paging.
因此,任何从MS来的上行数据都将做为一个有效的寻呼响应,并将在SGSN中MM上下文的状态变更为READY状态。 - The MS shall accept pages also in READY state if no radio resource is assigned. This supports recovery from inconsistent MM states in the MS and the SGSN.
如果没有分配任何空口资源的话,即使MS在READY状态也应接受这个寻呼。这将使得MS和SGSN的MM状态的不一致现象消除,并且同步。
