The encrypted location information of the BS may then be decrypted and based at least in part on the recovered location information of the BS, determine the location of the MS. In another implementation, in order to determine and provide the location of an MS of a wireless network, a combination of location agents, location controller, and a location server may be employed to determine and provide the current location of the MS to requesting authorized clients. | 09-04-2008 |

The method comprises forming a separate layer-three data link in a wireless network between a relay station, a base station and an access service network gateway (ASN-GW). Each separate layer-three data link is mapped from the ASN-GW to a next element in the wireless network to form a data path from the ASN-GW to the relay station. Data packets can be sent between a mobile station and the ASN-GW through each layer-three data link using a tunneling protocol such that each layer-three data link forms a separate tunnel. | 06-09-2011 |
| 20110134834 | Coordinating Broadcast Operations in a Mobile Wireless Network With Overlaid Cells - Advertising in connection with handing off a cell from one cell to another may be facilitated by segregating communication descriptors into a common part that does not change in different types of cells and a unique part that changes in different types of cells. The unique parts may be advertised more frequently than the common parts. | 06-09-2011 |
| 20110134896 | APPARATUS AND METHODS FOR UPGRADING AN AIRLINK IN A WIRELESS SYSTEM - Embodiments of systems and methods for upgrading an airlink in wireless system are described herein. Other embodiments may be described and claimed. | 06-09-2011 |
| 20110149876 | FEMTOCELL ARCHITECTURE AND NETWORK - A femtocell architecture and network are described. In one example the femtocell has a wireless access point having a first communications interface for wireless communications with a subscriber unit and a second communications interface for communications with a cellular radio communications system, and a secure gateway between the access point and the cellular system to secure communications between the access point and the cellular system. | 06-23-2011 |
| 20110159898 | Managing interference due to Low power BSs - A system and method for managing radio frequency interference of a low power base station is disclosed. The method comprises determining that the low power base station is causing substantial interference in a data link between a mobile station and a macro base station. The low power base station is identified as having a closed subscriber group (CSG) that is in CSG-Closed mode. The CSG low power base station is converted from CSG-Closed mode to a CSG-Open mode to allow the mobile station to communicate through the CSG low power base station. | 06-30-2011 |
