A method, system, and apparatus for communication in wireless communication network having an Access Service Network-controller (ASN-controller) communicating with plurality of Base Stations (BSs). The method includes reading one or more reports of plurality of reports received from the plurality of BSs. The plurality of reports comprise spare capacity information of one or more BSs of the plurality of BSs. The method further includes generating one or more directions based on the one or more reports to perform load balancing.

Method and apparatus for load balancing in a wireless communication network

A method of managing communication in the wireless communication network having a plurality of Base Stations (BSs) is provided. Each BS provides communication to one or more Mobile Stations (MSs) in an associated cell. The method includes re-using at a BS, channel allocated to collocated BSs to communicate with MSs located in a first predetermined region in a cell of the BS. The method further includes scheduling MSs located in the first predetermined region based on the position of each MS relative to the BS. The MSs are scheduled using one or more of channels allocated to the collocated BSs and a native channel of the BS. Further, the method includes scheduling MSs located in a second predetermined region based on the position of each MS relative to the BS. The MSs in the second predetermined region are scheduled using the native channel of the BS.

Method and system for spectrum reuse in the uplink in a wireless communication network

A method and apparatus for predicting a handover of a Mobile Station (MS) of a plurality of MSs to one or more target Base Stations (BSs) of a plurality of BSs in a wireless communication network. The method includes predicting a need for a handover of a MS to one or more target BSs selected from the plurality of BSs based on a handover threshold. The handover threshold is associated with a quality of a signal received by the MS. The method further includes transferring datapath associated with the MS to one or more of the one or more target BSs and one or more gateways prior to the handover of the MS. The one or more gateways are associated with one or more of a serving BS associated with the MS and the one or more target BSs. The plurality of BSs includes the serving BS.

A heterogeneous Access Service Network-Gateway (ASN-GW) in an ASN in a WiMAX communication network. The heterogeneous ASN-GW includes a radio resource module and a handover module. The radio resource module provides Radio Resource Management (RRM) to a set of BTSs in the ASN. A BTS operates in one of the second-profile and the first-profile. The handover module is operatively coupled with the radio resource module. The handover module provides handover management to at least one BTS.

The disclosure proposes an adaptive resource allocation in a network. A resource is divided into Blocks and each base station is assigned a Block for its subscribers that are in the interference region, and another Block for its subscribers that are not in the interference region. Blocks other than these two are not used by the base station. Bordering base stations does not use the same Block if they have any subscribers in the shared interference region. The disclosure proposes a resource sizing along with load balancing scheme. The resource sizing is adaptable and may change over time according to topology.

Method and apparatus for network wide adaptive resource allocation for OFDMA/TDMA networks

A method and apparatus for handover of a MS of a plurality of MSs to a BS of a plurality of BSs in a wireless communication network. The method includes identifying a target BS from the plurality of BSs for handover of the MS served by a serving BS. A difference between a quality of a signal received by the MS from the target BS and the quality of the signal received by the MS from the serving BS is greater than or equal to a first predefined threshold. The method further includes performing a handover for the MS from the serving BS to the target BS when the quality of the signal received by the MS from the serving BS is greater than or equal to a second predefined threshold.

A system and method of vehicular wireless communication over a Dedicated Short Range Communication service band is provided. The system includes a vehicle having a navigation means, a processor, and a communication means for transmitting a message via a wireless communications link. The system includes a control channel for communication a safety communication and a service channel for communicating a non-safety communication. The control channel is subdivided into a contention-free period having a safety exchange interval of time for transmitting a safety communication and a contention period having a non-safety service interval of time for transmitting a non-safety communication. The system further includes an access point in communication with the vehicle via the communications link within region. The method includes the steps of determining if the vehicle is within communications range of the region, determining if the vehicle is registered with the access point, and if the vehicle is within the communications range of access point, determining if a current time is within the safety exchange interval, and transmitting the safety communication by each registered vehicle during the safety exchange interval at the predetermined time for each registered vehicle. The method further includes the steps of determining if the safety communication exchange by every registered vehicle is completed, and permitting the vehicle to leave the control channel if the safety communication exchange is complete, and determining if a current time is within a contention period, and transmitting the non-safety communication if the current time is within the contention period.

The system includes a control channel for communicating a safety message and a service channel for communicating a non-safety message. The control channel is subdivided into a contention-free period having a safety exchange interval and a contention period having a non-safety service interval. The system further includes a dedicated group manager that partitions the vehicles into groups. The method includes the steps of determining if the vehicle is within communications range of the region, determining if the vehicle is registered with the group manager, if the vehicle is within the communications range of the group manager, determining if a current time is within the safety exchange interval, and transmitting the safety communication by each registered vehicle during the safety exchange interval at the predetermined time for each registered vehicle.
