Communication system for temporarily directing radio receivers to a second radio frequency

A radio communication system for communicating on at least two radio frequencies, the radio communication system, comprising:

• a receiver for receiving information addressed to at least one of a plurality of selective call receivers;
• a first transmitter for transmitting the information including a control signal therewith to at least one of the plurality of selective call receivers on a first radio frequency;
• a second transmitter for transmitting information on a second radio frequency;
• a paging terminal, coupled the receiver, and the first and second transmitters, determines when to transmit information on the second radio frequency by selecting the second transmitter;
• a microcomputer for generating the control signal to be transmitted on the first radio frequency in response to the paging terminal selecting the second transmitter for transmitting information to the at least one of the plurality of radio receivers;
• said at least one of the plurality of radio receivers, comprising:
• a receiver for receiving information and the control signal on the first radio frequency;
• a decoder for decoding the received information and the second radio frequency from the control signal being received on the first radio frequency;
• a controller coupled to the decoder for controlling the programming of said at least one of the plurality of selective call receivers to receive information on the second radio frequency in response to the control signal;
• said controller determines when to reprogram said at least one of the plurality of selective call receivers to return from the second radio frequency to the first radio frequency following a reception of information on the second radio frequency;
• an alerting device for alerting a user of the received information;
• and
• a display device for displaying the received information.

A radio receiver for receiving information on a least two radio frequencies, comprising:

• receiving means for receiving information and a control signal on a first radio frequency;
• decoder means for decoding the received information and a second radio frequency from the control signal being received on the first radio frequency;
• means for programming said receiving means to the second radio frequency for temporarily receiving information in response to the control signal;
• controller means, coupled to said programming means, for determining when to reprogram said receiving means to return from the second radio frequency to the first radio frequency within a predetermined time to continue receiving information and the control signal on the first radio frequency;
• alerting means for alerting a user of the received information;
• and
• displaying means for displaying the received information.

A selective call receiver for receiving information on a least two radio frequencies, comprising:

• a receiver for receiving information and a control signal on a first frequency;
• a decoder decodes the received information and a second radio frequency from the control signal being received on the first radio frequency;
• a microcomputer determines when to program said receiver to the second radio frequency responsive to the control signal for temporarily receiving information;
• said microcomputer determines when the receiver has received information on the second radio frequency wherein said microcomputer reprograms said receiver to return from the second radio frequency to the first radio frequency following the receiver receipt of information on the second radio frequency;
• an alerting device for alerting a user of the received information;
• and
• a displaying device for displaying the received information.

A method for communicating on at least two radio frequencies in a radio communication system, comprising the steps of:

• (a) receiving information addressed to at least one of a plurality of radio receivers on a first radio frequency;
• (b) transmitting the information including a control signal to the at least one of the plurality of radio receivers on the first radio frequency;
• (c) determining when to direct the at least one of the plurality of radio receivers to a second radio frequency for receiving information;
• (d) generating the control signal to be transmitted with the information to the at least one of the plurality of radio receivers on the first radio frequency;
• (e) receiving the information and the control signal by said at least one of the plurality of radio receivers on the first frequency;
• (f) decoding the received information and the second radio frequency from the control signal;
• (f1) transmitting information on the second radio frequency;
• (g) temporarily directing said at least one of the plurality of radio receivers to receive information on the second radio frequency;
• and
• (h) returning said at least one of the plurality of radio receivers from the second radio frequency to the first radio frequency D continue receiving information on the first radio frequency, said step of returning returns said at least one of the plurality of radio receivers to the first radio frequency when said at least one of the plurality of radio receivers has received information on the second radio frequency.

In a radio receiver, a method for receiving information on a least two radio frequencies, comprising the steps of:

• (a) receiving information on a first frequency wherein the information includes a control signal for temporarily directing said radio receiver to receive information on a second radio frequency;
• (b) decoding the received information and the second radio frequency from the control signal;
• (c) temporarily directing said radio receiver for receiving information on the second radio frequency;
• (d) receiving information on the second frequency;
• and
• (e) returning said radio receiver from the second radio frequency to the first radio frequency to continue receiving information, said step of returning returns the radio receiver from the second radio frequency to the first radio frequency when the radio receiver has received information on the second radio frequency.
