Connecting an UE to a basestation, with a quality of service and an allowed CSG service priority
View Patent ↗The disclosure includes a method in a cellular communications network, and a User Equipment, basestation and network management entity for implementing the method, the method comprising: a first basestation transmitting a first message including a Closed Subscriber Group (CSG) identifier; determining, for a User Equipment (UE) whether the CSG identifier is present on a first allowed CSG list; determining the allowed service level for the UE, the allowed service level indicating one of at least a first and second allowed service level; and connecting the UE to the first basestation if the CSG identifier is present on the first allowed CSG list, wherein the Quality of Service (QoS) for the UE is dependent on the allowed service level.
1. A method in a cellular communications network, the method comprising:
transmitting, by a first basestation, a first message including a Closed Subscriber Group (CSG) identifier;
determining for a User Equipment (UE) that the CSG identifier is present on a first allowed CSG list;
determining an allowed CSG service priority level for the UE based on the CSG identifier, the allowed CSG service priority level being selected from the group consisting of a first CSG service level and a second CSG service level, the first CSG service priority level providing a different level of service than the second CSG service priority level; and
connecting the UE to the first basestation, wherein the Quality of Service (QoS) for the UE is dependent on the allowed CSG service priority level.
2. A method as claimed in claim 1 , further comprising:
the UE receiving the first message,
wherein the UE stores a first copy of the first allowed CSG list and determines that the CSG identifier is present on the first allowed CSG list.
3. A method as claimed in claim 2 , wherein a network management entity stores a second copy of the first allowed CSG list, the method further comprising:
the network management entity determining that the CSG identifier is present on the second copy of the first allowed CSG list.
4. A method as claimed in claim 3 , further comprising:
the UE sending a handover initiating message to a second basestation, the handover initiating message including the CSG identifier for the first basestation and a UE identifier; and
the network management entity receiving the CSG identifier and the UE identifier from the second basestation;
wherein the stored second copy of the first allowed CSG list was retrieved by the network management entity based on the UE identifier.
5. A method as claimed in claim 1 , wherein, by determining that the CSG identifier is present on the first allowed CSG list, the allowed CSG service priority level of the UE is determined to be the first CSG service priority level.
6. A method as claimed in claim 1 , wherein the first allowed CSG list indicates the allowed CSG service priority level.
7. A non-transitory computer-readable storage medium storing a computer program or suite of computer programs which, upon execution by a computer system, performs the method of claim 1 .
