The radio access network identifies the plurality of femto cells bordering the macro subnet, and assigns the established first and second color codes to the identified border femto cells, while assigning only the first color code to non-bordering femto cells. | 04-16-2009 |
| 20090098890 | Methods of locating, paging and routing calls to wireless users in femto system - In a method for locating a mobile station, a first sub-paging zone for paging the mobile station is selected in response to an incoming call intended for the mobile station if a trigger code associated with a first femto cell matches a first trigger code associated with femto cells included in the first sub-paging zone. The first femto cell is a femto cell with which the mobile station has most recently registered. The first sub-paging zone is defined based on a location of ones of a subset of the plurality of femto cells. The mobile station within the first sub-paging zone is paged to locate the mobile station. | 04-16-2009 |
| 20090207805 | Pre-registration, storing of pre-registration session information and session transfer in a wireless communication system - Example embodiments are directed to a system and methods of pre-registration, storing of pre-registered session information and session transfer, which may occur when an access terminal is in close proximity to a border area between a first radio access technology (RAT) area and a second RAT area. A method includes obtaining pre-registration session information if an access terminal enters a pre-registration zone, starting a pre-registration session information timer associated with the obtained pre-registration session information, and storing the obtained pre-registration session information until the associated pre-registration information timer expires. Further, both an access terminal and an access network include one or more memories configured to store more than one group of pre-registration session information and more than one timer. Each of the timers are associated with a corresponding set of pre-registration session information. | 08-20-2009 |
