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.
Claims20
A mobile node selectably operable in a communication system to communicate data by way of a radio link with a network part, said mobile node facilitating channel capacity allocation upon the radio link, said mobile node comprising:
- a channel allocation request generator selectably operable when data is available to be communicated by the mobile node to the network part, said channel allocation request generator for selectably generating a channel allocation request to communicate the data from the mobile node to the network part;
- and
- a selector operable at least absent of detection at the mobile node of a response to at least an initial channel allocation request generated by said channel allocation request generator and determination that radio communication conditions on the radio link are inadequate, said selector for selecting when to cause said channel allocation request generator to generate at least a first subsequent channel allocation request, said selection made by said selector to delay generation of the first subsequent channel allocation request for a selected delay period at least while the radio communications remain inadequate.
A method of communicating in a radio communication system in which a mobile node selectably communicates data by way of a radio link with a network part, said method for controlling state transitions between mobile-node states pursuant to initiation of allocation of channel capacity upon the radio link, said method comprising:
- placing the mobile node in a first operational state in which the mobile node is permitted to request the allocation of the channel capacity upon the radio link;
- monitoring communication indicia on the radio link;
- placing the mobile node in a second operational state in which the mobile node remains permitted to request the allocation of the channel capacity upon the radio link responsive to indications that the communication indicia monitored during said operation of monitoring is beneath a first threshold level;
- and
- placing the mobile node in a third operational state in which the mobile node is prohibited from requesting the allocation of the channel capacity if the mobile node is unable, while in the second operational state, to detect a response to the channel allocation request.
A method for facilitating initiation of allocation of channel capacity upon a radio link in a radio communication system in which a mobile node selectably communicates data with a network part of the radio communication system by way of the radio link, said method comprising the steps of:
- selectably generating an initial channel allocation request by the mobile node, to communicate data from the mobile node to the network part when data is available to be communicated by the mobile node to the network part;
- and
- selecting when to cause generation of at least a first subsequent channel allocation request absent detection at the mobile node of a response to the initial channel allocation request and upon determination that radio signal strength between the mobile node and network part on the radio link is inadequate.
