Method and system for processing bearer under ISR mechanism
First Claim
1. A method for processing a bearing procedure under an idle mode signaling reduction (ISR) mechanism, comprising:
- receiving, by a serving gateway (SGW), a create bearer request sent by a packet data network gateway (PGW);
storing, by the SGW, the create bearer request, and notifying a mobility management entity (MME) and a Service GPRS Support Node (SGSN) to page a user equipment (UE);
receiving, by the SGW, a notification about an access mode of a current network; and
notifying, by the SGW, the PGW of the access mode of the current network.

Abstract
A method and a system for processing a bearer under an idle mode signaling reduction (ISR) mechanism are provided. The method for processing a bearer under an ISR mechanism includes the following steps. A mobility management network element acquires an access mode of a current network. The mobility management network element notifies a serving gateway (SGW) of the access mode of the current network, so that the SGW processes bearer according to the access mode of the current network. It can be ensured that the access mode of the current network is consistent with the access mode for a policy and charging control (PCC) strategy adopted during a bearing procedure under the ISR mechanism.
