Abstract: Systems and methods are disclosed for a 3G gateway. In a first embodiment, a method is disclosed for a network, comprising: receiving a relocation request message at a home nodeB gateway (HNBGW), the HNBGW coupled to an operator core network, the relocation request message including a target super cell identifier and a user equipment (UE) identifier; sending a second relocation request message from the HNBGW to a coordinating node, the coordinating node having as its identifier the target super cell identifier; querying a lookup table at the coordinating node using the UE identifier to determine a target cell identifier; replacing, in the second relocation request message, the target super cell identifier with the target cell identifier to create a third relocation request message; and sending the third relocation request message to a target cell identified by the target cell identifier.

Abstract: A method is disclosed for reducing processor utilization at a cellular base station, comprising: sending a number of random access preambles in a System Information Block (SIB) that may be less than 64; subtracting the number of random access preambles from 64 to obtain a ceiling of dedicated preambles; and using root sequences to generate a number of dedicated preambles less than or equal to the number of random access preambles, thereby reducing processor utilization relative to generating 64 preambles.
