Abstract
An apparatus and method for a spanning tree network. A communication device (160, Fig.1) can connect to a piconet network (100) and the communication device can transmit at least one available piconet identifier prior to receiving a request for the available piconet identifier from a dependent communication device (180), the available piconet identifier providing a parent piconet coordinator identification for the dependent communication device. A dependent communication device can connect to the piconet network, determine if the communication device can support a dependent piconet, and receive at least one available piconet identifier prior to requesting information regarding establishing a dependent piconet, the available piconet identifier providing parent piconet identification for the communication device for the dependent piconet.
Claims
1. A method in a communication device of communicating between other devices in a piconet network, the method comprising: connecting to the piconet network; and transmitting at least one available piconet identifier prior to receiving a request for the available piconet identifier, the available piconet identifier providing parent piconet coordinator identification; wherein the method further comprises transmitting information for the calculation of a block of available piconet identifiers, the size of the block of available piconet identifiers being based on a maximum number of desired piconet coordinators, and wherein the size of the block of available piconet identifiers is based on a maximum number of desired piconet coordinators and a maximum number of levels of piconet coordinators.
2. The method according to claim 1, wherein the available piconet identifier is transmitted in a beacon of a superframe.
3. The method according to claim 1 , further comprising receiving a request to become a dependent piconet coordinator capable of establishing a dependent piconet, the request including the available piconet identifier.
4. The method according to claim 1 , wherein the piconet network comprises a collection of a pi urality of logically associated devices mat share a single identifier with a common coordinator.
5. A communication device for communicating between other devices in a piconet network, the apparatus comprising: a transceiver configured to connect to the piconet network; and a controller coupled to the transceiver, the controller configured to transmit, via the transceiver, at least one available piconet identifier prior to receiving a request for the available piconet identifier, the available piconet identifier providing a parent piconet coordinator identification for the communication device, wherein the controller is further configured to transmit, via the transceiver, information for the calculation of a block of available piconet identifiers, the size of the block of available piconet identifiers being based on a maximum number of desired piconet coordinators, and wherein the size of the block of available piconet identifiers is based on a maximum number of desired piconet coordinators and a maximum number of levels of piconet coordinators.
6. The communication device according to claim 5, wherein the available piconet identifier is transmitted in a beacon of a superframe.
7. The communication device according to claim 5, wherein the controller is further configured to receive, via the transceiver, a request to become a dependent piconet coordinator capable of establishing a dependent piconet, the request including the available piconet identifier.
8. The communication device according to claim 5, wherein the piconet network comprises a collection of a plurality of logically associated devices that share a single identifier with a common coordinator.
9. A communication device for communicating between other devices in a piconet network, the communication device comprising: a transceiver configured to connect to the piconet network; and a controller coupled to the transceiver, the controller configured to determine if the communication device can support a dependent piconet, the controller further configured to receive, via the transceiver, at least one available piconet identifier prior to requesting information regarding establishing a dependent piconet, the available piconet identifier providing parent piconet identification for the communication device for the dependent piconet, wherein the controller is further configured to calculate a block of available piconet identifiers, the size of the block of available piconet identifiers being based on a maximum number of desired piconet coordinators, and wherein the size of the block of available piconet identifiers is based on a maximum number of desired piconet coordinators and a maximum number of levels of piconet coordinators.
10. The communication device according to claim 9, wherein the information regarding establishing a dependent piconet includes an indicator indicating a desire to become a dependent piconet coordinator capable of establishing a dependent piconet.
