A second security assessment () associated with each of a plurality of subsequent network connections available between the plurality of base stations () and a target destination system () is performed. A set of base station connections from the plurality of base station connections are prioritized according to predetermined security criteria associated with the wireless device (). A set of subsequent network connections from the plurality of subsequent network connections () are prioritized according to predetermined security criteria associated with the wireless device ().

Security based network access selection

A method, system and communication network for transmitting information signals via uplink (UL) collaborative SDMA, in a wireless communication system. Base station receiver estimates a channel gain associated with the transmission path(s) of each user and keeps a matrix of normalized covariance, between users. Based on the estimated channel gain and the normalized covariance, ULS utility is able to compute channel capacity. Based on capacity estimates of (1) the multiplexed user signals and (2) the individual user signals, signals are either multiplexed for UL SDMA or are transmitted individually. An optimal selection of multiplexed signals may be based upon: (1) a cross user interface measurement; and (2) a selection mechanism based on eigen-decomposition techniques. The ULS utility enables a UL scheduler to pair information signals with clear spatial distinction and minimal correlation, based on capacity evaluations.

An apparatus and method for fractional frequency reuse in a communication system. The method includes a first stepof partitioning a sub-frame into resource partitions, wherein at least one resource partition has frequency reuse of one and all other resource partitions have frequency reuse greater than one. A next stepincludes scheduling resources for a mobile station in a sector in each resource partition used by that sector.

A subscriber unit () with multiple receive antennas () and a single transmit antenna () derives beamforming weights to be used at a base station () with multiple transmitting antennas (, and). The downlink beamforming weights are derived at the subscriber unit () from a prior downlink transmission from the base station () to the subscriber device () and an uplink sounding signal is used to carry derived downlink beam forming weights to the base station (). Downlink antenna specific pilots (without weight) are used at the subscriber device () to determine the beamforming weights. Decimated sounding signals, where the number of sounding subcarriers is at least the same as the number of antennas at the base station (), allow multiple users to sound at the same time.

A communication system provides network-based battery power management that may be transparent to a user of a mobile station (MS). When one or more elements of a network of the communication system determines that the MS is operating at a low power supply charge level and/or has experienced a significant change in a charging level of the power supply, the one or more network elements may arrange for postponement of delivery of a delay-tolerant service to the MS or for adjustment of one or more of a characteristic of a service provided to the MS and a parameter of a radio communication with the MS, including restoration of full services to an MS whose power supply charge level has been restored.

The present invention is a communication network () and method for monitoring location capabilities of mobile stations () in a database () of a communication network. Initially, the network receives an identification number from a mobile station (). If the database () does not include a location capability corresponding to the identification number, then a processor () requests the location capability from the mobile station () and stores the requested location capability in the database (). The location capability includes one or more of the following capabilities: an autonomous mode capability, an assisted mode capability and a legacy mode capability. To retrieve an entry from the database (), the network reads the location capability corresponding to the identification number from the database (). The network then assembles an assistance message based on the location capability of the mobile station () and transmits the assistance message to the mobile station ().
