| 20090052395 | Femto-BTS RF access mechanism - Femto cells that extend mobile network coverage into customer premises operate in a frequency band typically assigned to a macro network. As disclosed, to facilitate system discovery and registrations of mobile stations with femto cells, a carrier designates one the channels within the band as a primary channel for its femto cells. For example, neighbor list messages transmitted by macro network base stations can provide frequency and PN code information directing mobile stations to search the primary channel for a PN code of the femto cells. Also, a mobile station PRL may identify femto cells by SID/NID. The SID is that of the carrier's macro network, whereas the NID may be a NID of the macro network or one specifically assigned to femto cell operations. The PRL uses frequency acquisition information for the femto cells that is the same as or similar to that for one of the macro networks. | 02-26-2009 |
| 20090061873 | Active service redirection for a private femto cell - A femto cell at a customer premises, such as an IP-based femto Base Transceiver System (IP-BTS), can be configured as a “private access” node intended to service a limited set of mobile stations. However, mobile stations not associated with the private femto cell may acquire and lock onto the femto BTS. To avoid service blockages in such cases, the private femto BTS will allow call access attempts by, and call deliveries to, a non-associated mobile station, despite the “private access” configuration. However, upon completion of call set-up, the non-associated mobile station is directed to initiate handoff, from the private femto cell coverage provided by the femto BTS into a cell coverage of a base station of the macro network, to conserve femto cell resources for use in servicing calls of the associated mobile station(s). | 03-05-2009 |

| 20110149782 | METHODOLOGY TO ANALYZE SECTOR CAPACITY IN DATA-ONLY MOBILE-WIRELESS NETWORK - Infrastructure network service measurements of time needed to complete data transfers are used to determine the capacity of a technology sector of a wireless packet data communication base station, such as a 1xEV-DO sector, using infrastructure network service measurements. The process, for example, may predict when the radio-frequency link between wireless data subscribers and a wireless base station becomes sufficiently congested that each user experiences reduced data speeds. The determination of capacity can be made down to the sector-carrier (a single carrier within a base station sector) level. The prediction can be cast in terms of time, which allows network service providers to plan the growth of their base stations to meet subscriber needs. | 06-23-2011 |
| 20110188456 | METHOD TO IDENTIFY VOICE OVER PACKET DEVICE CAPABILITY AND USE IT TO MAKE APPROPRIATE CALLS WITH OTHER CLIENT DEVICES - A system provides push-to-talk (PTT) or similar communication service via a radio access network providing wireless mobile packet data communications for mobile stations. A server distributes packets of digitized audio received from a broadcasting mobile station to one or more client devices of other parties. The called client device(s), however, may not all have the same communications capabilities as the broadcasting mobile station. Signaling procedures are adapted to inform the broadcasting station of the capabilities of the other client device(s). This enables the broadcasting mobile station to configure its transmissions of digitized audio through the network for compatibility with the capabilities of the other client device(s). Proper configuration avoids loss of data at the destination, particularly at the start of a PTT transmission, due to transmission in a form or configuration that may be incompatible with one or more of the receiving stations. | 08-04-2011 |
| 20120108234 | FEMTO-BTS RF ACCESS MECHANISM - Femto cells that extend mobile network coverage into customer premises operate in a frequency band typically assigned to a macro network.

For example, neighbor list messages transmitted by macro network base stations can provide frequency and PN code information directing mobile stations to search the primary channel for a PN code of the femto cells. The mobile station preferred roaming list (PRL) may identify femto cells by SID/NID. The SID is that of the carrier's macro network, whereas the NID may be a NID of the macro network or one specifically assigned to femto cell operations. The PRL uses frequency acquisition information for the femto cells that is the same as or similar to that for one of the macro networks. | 05-03-2012 |
