METHOD, SYSTEM, NETWORK SIDE DEVICE, AND UE OF MANAGING CSG MEMBERSHIP
First Claim
1. A method of managing closed subscriber group (CSG) membership, comprising:
- detecting, by a network side, a change of CSG membership of a user equipment (UE) when the UE camps on a CSG cell and establishes a default bearer; and
when detecting the change of the CSG membership of the UE, triggering, by the network, a Detach procedure between the network side and the UE by using an existing path between the network side and the UE, and indicating state information about the CSG membership of the UE, wherein the state information is configured to instruct the UE to perform an operation with respect to the change of the CSG membership according to the state information.

Abstract
The present invention discloses a method, system, network side device, and UE of managing CSG membership. The method includes: detecting, by a network side, a change of CSG membership of a UE when the UE camps on a CSG cell and establishes a default bearer; and when detecting the change of the CSG membership of the UE, triggering, by the network, a Detach procedure between the network side and the UE by using an existing path between the network side and the UE, and indicating state information about the CSG membership of the UE, where the state information is used to instruct the UE to perform an operation with respect to the change of the CSG membership according to the state information.

13. A method of managing closed subscriber group (CSG) membership, comprising:
-
receiving a request message sent by a user equipment (UE) for emergency access to a CSG cell; obtaining a CSG identity (CSG ID) of the CSG cell according to the request message; determining that the CSG ID of the CSG cell is in a CSG membership list of the UE on a network side; and sending a request reject message to the UE, wherein the request reject message carries information indicating that the UE is a member of the CSG cell and notification information instructing the UE to initiate normal access to the CSG cell again.

14. A network side device, comprising:
-
a detecting unit, configured to detect a change of closed subscriber group (CSG) membership of a user equipment (UE) when the UE camps on a CSG cell and establishes a default bearer; and a managing unit, configured to;
when the detecting unit detects the change of the CSG membership of the UE, trigger a Detach procedure between the network side and the UE by using an existing path between the network side and the UE, and indicate state information about the CSG membership of the UE, wherein the state information is configured to instruct the UE to perform an operation with respect to the change of the CSG membership according to the state information. - View Dependent Claims (15, 16, 17, 18, 19)
