摘要:
A system and method for updating a security key at a base station (BS) is disclosed. The method comprises the operation of transmitting a handover command from the base station to a mobile station. The operation of incrementing a base station instance of an authentication key counter at the base station follows. The next operation of the method can be calculating a new local authentication key (AK*) at the base station using the base station instance of the authentication key counter and an authentication key (AK). The AK may be previously obtained from an authenticator. The method further includes communicating by the base station with the mobile station using the new local authentication key after a predetermined action time.

A zone switching method is disclosed for use in a mixed-mode WiMAX environment. The zone switching method is useful in a WiMAX network having both 802.16e (legacy) and 802.16e/802.16m (mixed-mode, or advanced) entities, including mobile stations, base stations, and access service network entities. The zone switching method includes anchor authenticator relocation, dual security context maintenance, and security updates for both entry-before-break-capable mobile stations and for those mobile stations with slower switching speeds. The zone switching method enables an advanced mobile station to seamlessly switch from legacy to mixed-mode operation once the mixed-mode entities are available to service the 802.16m operations.

Techniques to permit scheduling of mixed radio access technologies. In some cases, a first radio access technology mode of a base station is scheduled during a first time region and a second radio access technology mode of a base station is scheduled during a sleep mode of the first radio access technology mode. In some cases, a first radio access technology mode of a base station is scheduled during a first time region and a second radio access technology mode of a base station is scheduled during an unused portion of the first time region. In some cases, a femto-base station is scheduled to snoop for local mobile stations during a sleep mode. Inactive regions of mobile stations are scheduled during a portion of sleep modes of the radio access technology modes.

Efficient paging operation for femtocell deployment is generally presented. In this regard, a paging controller is introduced including a wired backbone interface to communicate with a plurality of macro base stations and a plurality of femto base stations, and control logic, the control logic to generate a page for a mobile station, and the control logic to transmit the page over the wired backbone interface to a select subset of all base stations, wherein the select subset of all base stations includes base stations that the mobile station is authorized to access. Other embodiments are also described and claimed.
摘要:
A method and system to facilitate mobile relay and group mobility in a wireless network. In one embodiment of the invention, the wireless network facilitates a mobile relay station that has logic to switch communication with a first base station to a second base station while maintaining logical communication with its associated mobile station(s). By doing so, the handover of the mobile relay station from a source base station to a target base station is transparent to the mobile station(s) that are connected with the mobile relay station in one embodiment of the invention.
摘要:
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.

Other embodiments are described and claimed.
摘要:
A method of managing network traffic within a wireless network (100) comprises identifying a plurality of base stations (111, 121, 131) within the wireless network, categorizing each one of the plurality of base stations according to its type, setting a load balancing parameter (α) for each one of the plurality of base stations according to its type, and, for a handover event involving a handover from a first one of the plurality of base stations to a second one of the plurality of base stations, selecting the second one of the plurality of base stations according to a process that takes into account the load balancing parameters of both the first one of the plurality of base stations and the second one of the plurality of base stations.
