Abstract
A Network node provides information to a base station indicating a list of forbidden frequency from which the base station may or may not offer services. The base station checks the received list of forbidden frequencies when considering whether to provide service to user equipments from a new tracking area or a certain access technology. The base may also transmit a list of allowed frequencies or the list of forbidden frequencies to user equipments to be used thereof. By introducing the possibility to set an amount of frequencies as forbidden in the area and access restriction information of user equipments, operators would be able to offer services like home base station in a simple way to customers.
Claims19
A method in a first base station (13) supporting a first cell for restricting frequency access in a wireless communication system having a plurality of base stations, characterized by the steps of:
- receiving, from a network node (11), a list of forbidden frequencies related to a mobile station;
- performing one of selecting allowed target cells for handover, based on the received list of forbidden frequencies, or transmitting, to the mobile station, allowable frequencies to be used.
A base station (13) for restricting frequency access in a wireless communication system, wherein said base station (13) is adapted to support a first cell and is characterized by:
- a radio transceiver (93);
- a network interface (94,95) adapted to receives from a network node a list of forbidden frequencies related to a mobile station,
- a controller unit (91), coupled to said transceiver and interface, and adapted to perform one of selecting allowed target cells for handover based on the received list of forbidden frequencies and providing the mobile station with allowable frequencies to be used.
