    Abstract: A system and method for locating a portable locator device in a communications network. The portable locator unit (PLU) (4) is activated either by an external signal (62) generated in response to remote activation source, such as a subscriber (6, 8) or PLU detector (106, 108), or by an internal activation signal triggered e.g. by the wearer. Once activated, the PLU (4) transmits a location signal (66). This location signal (66) is received by one or more network service nodes (20, 22, 24) which forward the information along with identifying service node information to a network location processor (26, 28). After having determined the location of the PLU (4) from the received information, the network location processor (26, 28) forwards this information to a designated source, such as the requesting subscriber or other authorized user (6, 8).

    Abstract: Cellular radiotelephone communication system cell site equipment has a radio frequency transmitter (240) operating as one signal frequency source and a first and a second signal combiner device (282) tuned to a first and a second signal frequency, respectively, each signal combiner device (282) having resonant cavity means for isolating a signal frequency source from other signal frequency sources. Each signal combiner device (282) has coupling means (210) for coupling the isolated signal frequency source to a respective common transmitter output. The system further comprises a radio frequency switching means (230), operatively coupled to the radio frequency transmitter (240), the first signal combiner device (282) and the second signal combiner device (282), for coupling the radio frequency transmitter (240) to either of the first and the second signal combiner devices (282).

    Abstract: A method and apparatus for multi-media communication includes transmitting a first session invite request (300) having a plurality of first call transaction identifiers (302), wherein each of the first call transaction identifiers (302) has a first call transaction value (303). Thereupon, the method and apparatus engages in a first communication session using the first session invite request (300). Concurrently, a second session invite request (400), having a plurality of second call transaction identifiers (402) having a second call transaction value (403), is also transmitted. A determination is made if the second session invite request (400) is duplicative by comparing the first and second call transaction values (303, 403) of the first and second call transaction identifiers (302, 402). A second communication session is engaged if the second session invite request (400) is not duplicative such that the first communication session and the second communication session create a multi-media session.
