Abstract
A method and system for communicating within a wireless communication network (200) is provided. The communication between Portable Subscriber Units (PSUs) (104 and 106) by using a Vehicular Repeater (110) over a conventional communication link (102) is attempted (404). If the conventional communication link attempt fails (406), the communication is initiated directly from one PSU (104) to at least one other PSU (106) by using a direct channel link (202).
Claims18
A method of communicating within a wireless communication network, comprising the steps of:
- providing Fixed Network Equipment (FNE) and a plurality of Portable Subscriber Unit (PSUs);
- attempting communication between one PSU and at least one other PSU by using a Vehicular Repeater (VR) over a conventional communication link;
- and
- communicating directly from the one PSU to the at least one other PSU by using a direct channel link when the conventional communication link fails;
- maintaining the direct channel link as long as voice is being transmitted from the one PSU to the at least one other PSU;
- starting a timer when the direct channel link is dropped,
- establishing subsequent communications by utilizing the direct channel link if the timer is within a predetermined time;
- and
- establishing subsequent communications by utilizing the conventional communication link if the timer has expired by using the conventional communication link by utilizing the VR and FNE.
A method of communicating within a wireless communication network, comprising the steps of:
- providing Fixed Network Equipment (FNE) and a plurality of Portable Subscriber Units (PSUs) capable of communicating via a conventional communication link by utilizing a Vehicular Repeater (VR);
- attempting the conventional communication link from one of the PSUs to the VR, the conventional communication link failing;
- automatically establishing a direct channel link between the one PSU and remaining PSUs without the VR, in response to the conventional communication link failing;
- temporarily maintaining the direct channel link as long as a voice signal is being transmitted from the one PSU to the remaining PSUs;
- starting a timer when the voice signal from the one PSU to the remaining PSUs is dropped;
- establishing subsequent communication by using the direct channel link, if the timer is within a predetermined time;
- and
- establishing subsequent communications by using the conventional communication link by utilizing the VR if the timer has expired by using the conventional communication link by utilizing the VR and FNE.
A wireless communication network, comprising:
- fixed network equipment (FNE);
- a single mobile vehicular repeater (VR);
- a plurality of portable subscriber units (PSUs) capable of communicating with each other via the single VR and FNE by utilizing a conventional communication link;
- a PSU from the plurality of PSUs communicating directly with remaining PSUs, without the FNE and single VR and without user input, by utilizing a direct channel link when the conventional communication link fails, wherein the direct channel link is maintained as long as a voice signal is being transmitted from the PSU to the remaining PSUs;
- wherein a timer is started when the voice signal from the PSU to the remaining PSUs is dropped;
- if the timer is within a predetermined time subsequent communication is established by using the direct channel link;
- and
- if the timer has expired subsequent communication is established by using the conventional communication link by utilizing the VR and FNE.
