Method and apparatus for dynamic group calling in a selective call system

A selective call receiver having at least one selective call address assigned thereto, the selective call receiver comprising:

• receiver circuitry for receiving a selective call signal;
• a first memory for storing the at least one selective call address assigned to the selective call receiver;
• an address decoder coupled to the first memory means and the receiver means for determining whether the selective call signal comprises signals matches one of the at least one selective call address;
• a message decoder coupled to the address decoder for decoding a selective call message in response to the address decoder determining that the selective call signal comprises signals matching one of the at least one selective call address;
• a second memory coupled to the message decoder for storing the selective call message;
• and
• a controller coupled to the second memory and the address decoder for determining whether the selective call message is a group call address, for providing the group call address to the address decoder as one of the at least one selective call address in response to determining the selective call message is a group call address, and for automatically erasing the group call address from the second memory in response to the address decoder determining that the selective call signal comprises signals matching the group call address.
