Abstract
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.
Claims15
A method in a cellular communications network, the method comprising:
- a first basestation transmitting 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 the allowed CSG service level for the UE, the allowed CSG service level being one of at least a first and second allowed CSG service 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 level.
A User Equipment (UE) for a cellular communications network, the UE comprising:
- a memory module adapted to store a database including a first allowed Closed Subscriber Group (CSG) list including a CSG identifier for a CSG, and an allowed CSG service level for each CSG identifier being one of at least a first and second allowed CSG service level;
- a transceiver adapted to receive a first message from a first basestation, the first message including the CSG identifier for the CSG;
- and
- a processor adapted to determine that the CSG identifier in the first message is present in the first allowed CSG list, and to determine the allowed CSG service level for the CSG identifier in the first message.
A basestation for a cellular communications network, the basestation comprising:
- a memory module adapted to store a first Closed Subscriber Group (CSG) identifier;
- a transceiver adapted to transmit the first CSG identifier and to receive a handover request message for a User Equipment (UE), the handover request message indicating that the UE is a CSG member and an allowed CSG service level for the UE being one of at least a first and second allowed CSG service level;
- and
- a processor adapted to connect the basestation and the UE, wherein the Quality of Service (QoS) for the UE is dependent on the allowed CSG service level.
A network management entity for a cellular communications network, the network management entity comprising:
- a transceiver adapted to receive a handover initiating message from a serving basestation, the handover initiating message including a Closed Subscriber Group (CSG) identifier and a User Equipment (UE) identifier;
- a memory module having a database to store a first CSG list for a UE, the first CSG list including at least one CSG identifier, and an allowed CSG service level for each CSG identifier being one of at least a first and second allowed CSG service level;
- and
- a processor adapted to retrieve the first CSG list for the UE using the UE identifier, to determine that the CSG identifier is present on the first CSG list for the UE, and to determine the allowed CSG service level for the UE.
