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.

comparing, by the SGW, the access mode of the current network with a recorded access mode of an original resident network;
wherein notifying the PGW the access mode of the current network further comprises:
sending, by the SGW, an update bearer request to the PGW when the access mode of the current network is different from the access mode of the original resident network, the update bearer request carries the access mode of the current network.', 'comparing, by the SGW, the access mode of the current network with a recorded access mode of an original resident network;', 'wherein notifying the PGW the access mode of the current network further comprises:', 'sending, by the SGW, an update bearer request to the PGW when the access mode of the current network is different from the access mode of the original resident network, the update bearer request carries the access mode of the current network.
5. The method according to claim 1, wherein the method further comprises:
sending, by the PGW, the access mode of the current network to a policy and charging rules function (PCRF) entity; and
acquiring, by the PGW, a policy and charging control (PCC) rule corresponding to the access mode of the current network from the PCRF entity.', 'sending, by the PGW, the access mode of the current network to a policy and charging rules function (PCRF) entity; and', 'acquiring, by the PGW, a policy and charging control (PCC) rule corresponding to the access mode of the current network from the PCRF entity.
6. The method according to claim 5, wherein the method further comprises:
initiating, by the PGW, a bearer activation process according to the acquired PCC rule corresponding to the access mode of the current network.', 'initiating, by the PGW, a bearer activation process according to the acquired PCC rule corresponding to the access mode of the current network.
7. A serving gateway (SGW), comprising:
a first receiving device, configured to receive a create bearer request sent by a packet data network gateway (PGW);
a first processing device, configured to store the create bearer request and notify a mobility management entity (MME) and a Service GPRS Support Node (SGSN) to page a user equipment (UE);
a second receiving device, configured to receive a notification about an access mode of a current network;
a second processing device, configured to notify the PGW of the access mode of the current network received by the second receiving device.', 'a first receiving device, configured to receive a create bearer request sent by a packet data network gateway (PGW);', 'a first processing device, configured to store the create bearer request and notify a mobility management entity (MME) and a Service GPRS Support Node (SGSN) to page a user equipment (UE);', 'a second receiving device, configured to receive a notification about an access mode of a current network;', 'a second processing device, configured to notify the PGW of the access mode of the current network received by the second receiving device.
