A mobile communication device (100) contains a memory (110), a controller (112) and transceiver components (120, 122, 124, 126). When an incoming call signal is received (314), the controller compares the source identifier with various lists (210, 240, 270) stored in the memory. If the source identifier is contained on a rejection list, the call is rejected. If the source identifier is contained on an acceptance list, the call is received normally, unless a do not disturb feature is active. The lists may be fixed or selectable. Selectable lists are configurable by the user of the mobile communication device, whereas fixed list types cannot be changed by the user of the mobile communication device. |

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward.
When an incoming call is received by a subscriber unit, the communication system transmits source identification information along with the call.
The incoming call can be a phone call from a telephone network, a private, or unit to unit call made directly from another subscriber unit, or a short message service or page call.
The subscriber unit then decides whether or not the call will be accepted, according to a set of rules stored in the subscriber unit.
If the rule set determines that the call may proceed, then the user is alerted to the incoming call and can respond.
If the rule set determines that the call should be rejected, the user is not alerted and the call is terminated.
Referring to FIG.
1, a block diagram of communication system 30 is shown, and includes a plurality of mobile stations or subscriber units, including a first subscriber unit 40 and a second subscriber unit 50.
The communication system may further include a communication system infrastructure 20.
The communication system 30 can be, for example, a two-way radio system or a cellular system.
The communication system infrastructure 20 is typically connected to a public switched telephone network (PSTN) 10 through communication link 15, such as a frame relay link.
The communication link 15 allows subscriber units of communication system 30 to communicate over the PSTN.
The first subscriber unit 40 can make a call to another subscriber unit, such as second subscriber unit 50.
The call can be directly from one subscriber unit over the air to the other subscriber unit, or it may be facilitated by the communication infrastructure 20.
Furthermore, the call can be a private call to a single other subscriber unit, or it can be to multiple other subscriber units
