Abstract: A method and a communication unit for communicating data based on frequency reuse by a plurality of transmitters (10, 20, 30). The transmitters (10, 20, 30) are coupled to a controller (40) that schedules communications of data during the repetitive time slots. Different frequency reuse patterns are used when scheduling critical and non-critical data transmissions. A first reuse pattern is used for scheduling the transmission of critical data, and a second reuse pattern is used for scheduling non-critical data. The invention can be applied to any inbound or outbound time slotted protocol that have message fragments spanning over one or more time slots. The reuse pattern can be varied slot by slot, o use a less aggressive reuse for communicating critical data and a more aggressive reuse for communicating non-critically data. As a result, data can be communicated more reliably a d throughput can be increased by protecting critical data transmissions via a less aggressive reuse.

Abstract: A method and corresponding apparatus for a first controller (106) and implemented in a second controller (110), arranged for providing messaging service to, respectively, a first load (203) and a second load (205), to cooperatively and dynamically allocate a resource (207) between these loads. The method allocates a first and second default portions (221, 231) of the resource (207), and schedules messages from the first and the second load (203, 205) within these default portions (221, 231). Any unused part (243) of the default portions is reported to the other controller and it schedules messages from its load within the unused part (241), thereby dynamically allocating the resource (207) between the first and second load (203, 205).

Abstract: A system, wireless device (306) and method determine that a wireless device (306) is detecting a triggering event. The triggering event includes detecting a WLAN border cell (210), detecting a first signal from an egress portal (302), or detecting a degradation in signal quality. The wireless device (306) then detects at least one signal from an egress portal (302), determines that the wireless device (306) is moving from the coverage area of a first communications system to the coverage area of a second communications system according to the order of signals received from the egress portal (302), initiates a registration sequence with the second wireless communication system in response to determining that the wireless device (306) is moving from the coverage area of the first communications system to the coverage area of the second communications system, and conducts present and subsequent calls via the second wireless communication system.
