COMMUNICATION SYSTEM AND METHOD FOR SELECTING ALTERNATIVE FREQUENCIES |
摘要 |
A communication system (100) that selects alternative data channels for communication including a cellular communication system (900) has a base station (106) coupled to a plurality of alternative data communication systems (112, 114, 116) that receive messages intended for a selective call device designated by an address. A data scheduler (104), coupled to the base station (106) and the plurality of alternative data communication systems (112, 114, 116), has a categorizer (404) for categorizing the message as being suitable for transmission on an alternative data channel, a controller (402) for coordinating a list of the alternative data communication systems suitable for transmitting the message and a selector (406) for selecting the alternative data channel for transmitting the message. A controller (105) encodes a selective call signal with the address and a vector and a transmitter transmits the selective call signal to the selective call device (102) on a control channel including the address for identifying the selective call device, the vector designating the alternative data channel.
