Abstract
Apparatus (48), and an associated method, for facilitating operation of a mobile node (12) operable in a communication system (10) to request allocation of communication capacity upon which to communicate data pursuant to a communication service. A channel allocation request generator (52) is selectably operable to generate requests for allocation of channel capacity upon which to communicate the data. A selector (54) selects when to cause the generator (52) to communicate the additional data packets. Selection is made to delay, or otherwise prevent, retransmission of requests, when a determination is made that the retransmission is unlikely to be successful.
Claims19
Apparatus for a mobile node operable to communicate data by way of a radio link, said apparatus for facilitating channel capacity allocation upon the radio link, said apparatus comprising:
- a channel allocation request generator configured to generate channel allocation requests to request allocation of channel capacity for communication of the data by the mobile node;
- and
- a selector configured to select generation of a subsequent channel allocation request by said channel allocation request generator, subsequent to generation of an initial channel allocation request by said channel allocation request generator, absent detection at the mobile node of a response to the initial channel allocation request and determination that radio communication conditions on the radio link are inadequate, selection by said selector of when to select the generation of the subsequent channel allocation request including selection to delay generation of the subsequent channel allocation request for a selected delay period at least while the radio communications remain inadequate.
A method for requesting allocation of channel capacity to a mobile node, said method comprising:
- generating, at the mobile node, up to a selected number of requests for the allocation of the channel capacity;
- detecting, at the mobile node, a response to any of the selected number of requests;
- and
- delaying generation, subsequent to detection during said detecting, of an additional request during times in which generation of the additional request appears unlikely successfully to be delivered.
