Abstract

A selective call controller, such as a paging terminal, and a method therefor is provided for receiving calls comprising first and second types of signal, such as numeric/alphanumeric or modem/DTMF. A determination is made of the type of signal being received, and a destination address and message signal is selected accordingly.

Claims

1. A selective call controller comprising:

means for receiving calls comprising a pager number coupled to a first or second type of message signal;

transmitting means for transmitting said calls to one or more selective call receivers corresponding to said pager number, the selective call receivers having at least two pager addresses corresponding to said two types of message signal;

means coupled to said receiving means for determining whether a received call comprises said first or second type of message signal; and

means coupled to said determining means and said transmitting means for selecting the pager address of said received call according to the determined message signal type thereof, whereby the call may be sent to that pager address.

2. The controller according to claim 1, wherein means are provided for testing whether the type of message signal is a first type wherein timer means are provided for timing a time-out period during which said test is carried out, and wherein means are provided for switching the controller from a first message signal type receive mode to a second message signal type receive mode after said time-out period if the test determines that the call does not comprise said first type of message signal.

3. The controller of claim 2, wherein the types of message signal are DTMF and modem modulated signals.

4. The controller of claim 1, wherein the first type of signal comprises tone signals indicative of the digits 0 to 9 plus at least one other tone signal and wherein means are provided in the controller for detecting said other tone signal and for switching from DTMF receive mode to a receive mode for receiving the other message signal type upon such detection.

5. The controller of claim 1, further comprising means for receiving a message signal of said first type, said message signal having an indication that it will subsequently be of the second type, means for identifying said indication and means for switching the controller from a first message signal type receive mode to a second message signal type receive mode upon such identification.

6. The controller of claim 5, wherein said indication comprises an unused receiver address.

7. The controller of claim 5, in combination with a call generating device adapted to generate calls comprising said second message signal type preceded by message signals of said first type including said indication.

8. The controller of claim 1, wherein said means for receiving calls comprises separate ports for receiving calls comprising said first and second types of message signal and wherein said message signal type determining means determines at which of said ports a call is received.

9. The controller of claim 1, wherein the first and second types of message signal comprise numeric and alphanumeric data respectively.

10. The controller of claim 9, wherein said message signal type determining means comprises means for inspecting the content of a call and determining that the type of message signal is alphanumeric if one or more alphabetic characters are present, and otherwise determining that the type is numeric.

11. The controller of claim 1 in combination with a selective call receiver having a first address for receiving message signals of said first type and a second address for receiving message signals of said second type.

12. The controller and receiver of claim 11, wherein the first and second types of message signal are selected from a group consisting of alphanumeric data, numeric data, voice and tone-only signals.

13. A method of operating a selective call system having first and second types of message generating devices operating with different types of message signal transmission format, the method comprising the steps of:

receiving a message signal for transmission to a selective call receiver;

determining which of said different types of format said message signal has; and

selecting a pager address of a message with the message signal according to the determined format of the message signal, whereby the message may be sent to a destination corresponding to said pager address.

14. A paging terminal, comprising:

call input means for receiving a paging call having a pager number coupled to message data including at least numeric or alphanumeric data;

transmitting means coupled to the call input means for transmitting a numeric data page to a first pager address and for transmitting an alphanumeric data page to a second pager address, the first and second pager addresses corresponding to the pager number; and

control means, coupled to the call input means and to the transmitting means, for determining from the received message data whether to transmit the numeric data page to the first pager address or to transmit the alphanumeric data page to the second pager address.

15. The paging terminal of claim 14, wherein the control means includes means for inspecting the received message data and determining to transmit the alphanumeric data page if one or more alphanumeric data characters are present in the received message data, and otherwise determining to transmit the numeric data page.
