Abstract:
1. A processor implemented apparatus for generating a compressed preferred roaming list (PRL): means for generating a subnet address by performing a bitwise AND operation on a network identification (ID) and a subnet mask, the subnet address consisting of a plurality of most significant bits and a plurality of least significant bits, the most significant bits of the subnet address representing a common part of a subnet to be factored out; means for storing the most significant bits of the subnet address in a subnet table; means for storing the least significant bits of the subnet address in a system table; means for factoring out at least one set of data common to two or more subnets; means for storing said at least one set of data common to said two or more subnets in the subnet table; means for generating an indicator for accessing said at least one set of data; and means for storing the indicator in the system table.
