Abstract
A method and apparatus for controlling communications between a base and a handset capable of communicating with each other on at least one communication channel within a channel set. The method involves transmitting a new channel message including a preferred channel identifier from the base to the handset, on different channels of the channel set until an acknowledgement signal is received from the handset. In response to the acknowledgement signal, the preferred channel identifier is stored in a base working channel transmit buffer. Further communications between the base and the handset are conducted on a communications channel identified by the preferred channel identifier.
Claims38
A base apparatus in a cordless telephone for communicating with a handset of said cordless telephone on at least one communications channel within a channel set, the base apparatus comprising:
- a) a receiver for receiving signals from said handset;
- b) a transmitter for transmitting signals from said base to said handset;
- c) a base working channel transmit buffer for storing a transmit channel indicator defining a channel on which said transmitter transmits said signal;
- d) a base processor in communication with said receiver, said transmitter and said base working channel transmit buffer, said base processor being programmed to:
- i) produce a first new channel message including a preferred channel identifier;
- ii) direct said transmitter to transmit said first new channel message in said signals transmitted from said base to said handset, on a channel defined by the contents of said base working channel transmit buffer;
- iii) successively load said base working channel transmit buffer with channel indicators corresponding to different channels within said channel set such that said first new channel message is successively transmitted on different channels;
- iv) receive an acknowledgement signal from said receiver when an acknowledgement signal is received from said handset;
- and
- v) in response to said acknowledgement signal from said receiver, maintain in said base working channel transmit buffer a channel indicator associated with a last channel on which said message was transmitted immediately before said acknowledgment signal was received such that further communications between said base and said handset are conducted on said last channel.
A method of controlling communications between a base and a handset capable of communicating with each other on at least one communications channel within a channel set, the method comprising:
- a) in response to at least one of a power up signal and channel noise measurement, transmitting from said base to said handset, a first new channel message including a preferred channel identifier, on different channels of said channel set until an acknowledgement signal is received from said handset;
- b) in response to said acknowledgement signal, storing in a base working channel transmit buffer, said preferred channel identifier;
- and
- c) conducting further communications between said base and said handset on a communications channel identified by said preferred channel identifier.
