Abstract
The present invention provides signaling protocols that enable an integrated cellular relaying system to support a call for a wireless terminal. In embodiments of the invention, the wireless terminal is redirected to a relaying path corresponding to at least one relaying station. A relaying station communicates with the wireless terminal and with other relaying stations. In addition, one of the relaying stations (that is configured in the relaying path) completes the relaying path by communicating with a base transceiver station.
Claims8
A method comprising:
- determining that a first base transceiver station (BTS) does not have a channel to support a call for a wireless terminal, the first BTS utilizing a first frequency spectrum;
- receiving a request to initiate a relaying path for the wireless terminal;
- determining the relaying path that utilizes at least one relaying station and a second BTS, the at least one relaying station utilizing a second frequency spectrum comprising:
- determining an available bandwidth for each of the at least one relaying stations and for the second BTS;
- calculating a reciprocal of the available bandwidth for the each of the at least one relaying stations and the second BTS;
- summing the reciprocals;
- and
- selecting the relaying path that corresponds to a minimum sum of the reciprocals;
- and
- sending an instruction to the first BTS and to the second BTS in order to initiate an establishment of the relaying path.
An apparatus comprising:
- an interface;
- a processor communicating with a plurality of base transceiver stations through the interface, the processor configured to:
- determine that a first base transceiver station (BTS) does not have a channel to support a call;
- receive a request to initiate a relaying path for the wireless terminal;
- send an instruction to the first BTS and to a second BTS in order to establish the relaying path;
- and
- determine the relaying path that utilizes at least one relaying station to the second BTS, wherein determining the relaying path comprises:
- determining an available bandwidth for each of the at least one relaying stations and for the second BTS;
- calculating a reciprocal of the available bandwidth for the each of the at least one relaying stations and the second BTS;
- summing the reciprocals;
- and
- selecting the relaying path that corresponds to a minimum sum of the reciprocals.
A computer-readable medium comprising computer executable instructions to enable a device to:
- determine that a first base transceiver station (BTS) does not have a channel to support a call;
- receive a request to initiate a relaying path for a wireless terminal;
- send an instruction to the first BTS and to a second BTS in order to initiate an establishment of the relaying path;
- and
- determine the relaying path that utilizes at least one relaying station to the second BTS, wherein determining the relaying path comprises:
- determining an available bandwidth for each of the at least one relaying stations and for the second BTS;
- calculating a reciprocal of the available bandwidth for the each of the at least one relaying stations and the second BTS.
- summing the reciprocals;
- and
- selecting the relaying path that corresponds to a minimum sum of the reciprocals.
