Abstract
When a wireless terminal attaches to the network, the wireless terminal is assigned a temporary identifier. Different sets of access restrictions are associated with different blocks of temporary identifiers. When a message and a corresponding temporary identifier is received by the network from a requesting wireless terminal, an access controller identifies the block to which the assigned temporary identifier belongs and determines the access restrictions associated with that block.
Claims30
A method of determining access restrictions for a wireless terminal, comprising:
- associating different sets of access restrictions with different blocks of temporary identifiers, each of said blocks comprising a range of temporary identifiers;
- receiving a message and a corresponding temporary identifier from a wireless terminal, the temporary identifier being selected from one of said blocks of temporary identifiers;
- identifying, from the temporary identifier associated with said message, the block to which the temporary identifier belongs;
- and
- determining the set of access restrictions associated with the identified block.
A base station for determining access restrictions for a wireless terminal, comprising:
- memory storing a local database that associates different sets of access restrictions with different blocks of temporary identifiers;
- a transceiver circuit to receive a message from a wireless terminal that has an associated temporary identifier selected from one of said blocks of temporary identifiers;
- and
- an access controller to control network access by said wireless terminal, said access controller configured to:
- identify, from the temporary identifier associated with said message, the block to which the assigned temporary identifier belongs;
- and
- determine the set of access restrictions associated with the identified block.
