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.

Claims

1. A method for processing a bearing procedure under an idle mode signaling reduction, ISR, mechanism, comprising:

acquiring an access mode of a current network; and

notifying a serving gateway (SGW), of the access mode of the current network, so that the SGW performs bearer processing according to the access mode of the current network.

2. The method according to claim 1, wherein acquiring the access mode of the current network comprises:

receiving a bearer request or a notification message of paging a user initiated by the SGW; and

initiating a user paging to acquire the access mode of the current network according to the bearer request or the notification message of paging a user.

3. The method according to claim 2, wherein the bearer request carries an access mode of an original resident network, and after acquiring the access mode of the current network, the method further comprises:

comparing the access mode of the current network with the access mode of the original resident network, wherein when the access mode of the current network is different from the access mode of the original resident network, the access mode of the current network is performed and the access mode of the current network is notified to the SGW.

4. A method for processing a bearing procedure under an idle mode signaling reduction, ISR, mechanism, comprising:

receiving an access mode of a current network sent by a mobility management network element; and

performing a bearer processing according to the access mode of the current network.

5. The method according to claim 4, wherein after receiving the access mode of the current network, the method further comprises:

comparing the access mode of the current network with a recorded access mode of an original resident network, wherein when the access mode of the current network is different from the recorded access mode of the original resident network, and the bearer processing is performed according to the access mode of the current network.

6. The method according to claim 4, further comprising:

receiving a bearer request sent by a packet data network gateway (PGW); and

notifying the mobility management network element to page a user.

7. The method according to claim 4, wherein performing bearer processing according to the access mode of the current network comprises:

sending the access mode of the current network to a policy and charging rules function (PCRF) entity;

acquiring a policy and charging control (PCC) rule corresponding to the access mode of the current network from the PCRF entity; and

sending a create bearer request corresponding to the access mode of the current network according to the PCC rule corresponding to the access mode of the current network.

8. The method according to claim 4, wherein performing bearer processing according to the access mode of the current network comprises:

sending the access mode of the current network to a PCRF entity;

acquiring a PCC rule corresponding to the access mode of the current network from the PCRF entity; and

sending a bearer modifying request corresponding to the access mode of the current network according to the acquired PCC rule corresponding to the access mode of the current network after finishing the bearer processing.

9. The method according to claim 4, wherein after receiving the access mode of the current network, the method further comprises:

notifying a PGW of the access mode of the current network; and

receiving a bearer request corresponding to the access mode of the current network sent by the PGW according to the PCC rule corresponding to the access mode of the current network.

10. A mobile network system, comprising:

a mobility management network element configured to acquire an access mode of a current network; and

a serving gateway (SGW) configured to acquire the access mode of the current network from the mobility management network element, and perform a bearing procedure according to the access mode of the current network.

11. The mobile network system according to claim 10, further comprising:

a policy and charging rules function (PCRF) entity configured to receive the access mode of the current network sent by the SGW, and provide a policy and charging control (PCC) rule corresponding to the access mode of the current network for the SGW.

12. The mobile network system according to claim 11, further comprising:

a packet data network gateway (PGW) configured to send the access mode of the current network acquired by the SGW to the PCRF entity, and initiate a bearing procedure according to the PCC rule corresponding to the access mode of the current network provided by the PCRF entity.

13. A mobility management network element, comprising:

an acquisition unit configured to obtain an access mode of a current network; and

a notification unit configured to notify a serving gateway (SGW) of the access mode of the current network acquired by the acquisition unit.

14. The mobility management network element according to claim 13, wherein the acquisition unit comprises:

a receiving unit configured to receive a bearer request initiated by the SGW or receive a notification message of paging a user initiated by the SGW; and

a paging unit configured to initiate a user paging to obtain the access mode of the current network according to the bearer request received by the receiving unit.

15. The mobility management network element according to claim 14, wherein the bearer request received by the receiving unit carries an access mode of an original resident network, and the mobility management network element further comprises:

a comparison unit configured to compare the access mode of the current network with the access mode of the original resident network, wherein when a comparison result indicates that the access mode of the current network is different from the access mode of the original resident network, the notification unit notifies the SGW of the access mode of the current network.

16. A serving gateway (SGW), comprising:

a receiving unit configured to receive an access mode of a current network sent by a mobility management network element; and

a bearer processing unit configured to perform bearer processing according to the access mode of the current network received by the receiving unit.
