Abstract
A mobile terminal in a wireless communication network may be one of several modes of operation. When in an idle mode, the mobile terminal may avoid a lengthy random access procedure normally associated with responding to a page from a base station, if the base station includes in the page an indication of a resource that the mobile terminal may utilize when responding to the page. Additionally, the mobile terminal may transmit an efficient location update MAC header to a base station, whether prompted to by a page from the base station or not. Furthermore, without leaving the idle mode or a sleep mode, the mobile terminal may exchange short data burst messages with a base station.
Claims14
At a mobile terminal in a wireless communication system, a method of initiating communication with a base station, said method comprising:
- selecting a candidate pseudorandom noise code from a plurality of predefined pseudorandom noise codes;
- transmitting said candidate pseudorandom noise code to said base station;
- receiving an allocation message from said base station, where said allocation message indicates an allocated resource;
- and
- transmitting a location update Media Access Control header to said base station, where said transmitting said location update Media Access Control header utilizes said allocated resource;
- wherein said location update Media Access Control header includes a field for a reduced-length version of a Media Access Control address for said mobile terminal.
At a mobile terminal in a mobile communication system, a method of initiating communication with a base station, said method comprising:
- receiving a paging message from said base station;
- responsive to said receiving said paging message, transmitting a location update indicator message to said base station;
- receiving an allocation message from said base station, where said allocation message indicates an allocated resource;
- and
- transmitting a location update Media Access Control header to said base station, where said transmitting said location update Media Access Control header utilizes said allocated resource;
- wherein said location update Media Access Control header includes a field for a reduced-length version of a Media Access Control address for said mobile terminal.
