A system, wireless device () and method determine that a wireless device () is detecting a triggering event. The triggering event includes detecting a WLAN border cell (), detecting a first signal from an egress portal (), or detecting a degradation in signal quality. The wireless device () then detects at least one signal from an egress portal (), determines that the wireless device () 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 (), initiates a registration sequence with the second wireless communication system in response to determining that the wireless device () 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.

A method and system () for optimizing transcoder resources in a multimedia session is disclosed. The method includes receiving () one or more SDP offers. The method further includes filtering () out media types from each of the one or more SDP offers based on a rating range. Further, the method includes selecting () one of the media types from each of the one or more SDP offers. The method further includes allocating () resources of one or more transcoders for transcoding the one of the media types.

A wireless device for use in an ad hoc network is provided. The wireless device includes a transceiver, a global positioning system, and a controller. The transceiver is capable of receiving positional information from a plurality of remote users. The global positioning system is capable of generating positional information regarding the wireless device. The controller selects a first portion of the plurality of remote users to be within a pro active region of the ad hoc network based upon the positional information, and then maintains information on the remote users selected to be within the pro active region.

Fast call set-up for a call to a multi-mode communication unit () is facilitated by a method and apparatus for registering and re-registering priorities with a SIP registrar (). A list of contacts with first priorities associated with a mode of operation in a first enterprise network () is established and used. A switch to second priorities is made when a probability of a switch from the first mode of operation to a second mode of operation in a second cellular network () satisfies a threshold. The list of contacts includes a contact having an expiration time for the first mode of operation. A quality factor is determined and the list of contacts is re-registered and the expiration time changed if the quality factor does not satisfy a threshold.

According to the present invention, different frequency reuse patterns are used when scheduling critical and non-critical data transmissions. More specifically, the present invention uses a first reuse pattern for scheduling the transmission of critical data and a second reuse pattern for scheduling the transmission of 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, to use a less aggressive reuse for communicating critical data and a more aggressive reuse for communicating non-critical data. As a result, data can be communicated more reliably and throughput can be increased by protecting critical data transmissions via a less aggressive reuse.

Communication system that provides extra protection when transmitting critical data

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