A method and apparatus that process messages within a wireless communications system based on originator priority and recipient priority is accomplished when a server (12, 52) receives a message from an originating party (50). The message includes identity of the receiving party (54), originator priority information, and message content. Upon identifying the receiving party, the server retrieves recipient priority information of the receiving party. The server then merges the originator priority information with the recipient priority information to produce a message priority. In addition, the server generates a recipient index, which identifies an address for subsequent retrieval of the message content. Next, the server provides notice of the message to the receiving party based on the message priority. The notice of the message may be sent to the receiving party's pager, cellular telephone, e-mail account, facsimile machine, wireline telephone, or answering service.

Method and apparatus for processing messages based on originator and

In a wireless communication system (100, 200), at least one service building block (605-610 and 622) is used in a service creation environment (301) to create logic program rules (303) that include identification of an authorized service execution environment. The logic program rules, which may require further configuration, are provided to a service execution environment (302) having an identification that matches the identification of the authorized service execution environment. Configurable software modules within the service execution environment are executed in accordance with the logic program rules when at least one predetermined stimulus is detected, thereby providing the service within the system. The service creation environment and the service execution environment may be implemented within a single console or separately implemented within different consoles, or the service creation environment can be embodied within a stand-alone computer (201). In this manner, rapid service creation is provided.

The following describes an apparatus for and method of providing and supporting distributed call handling over a plurality of network nodes (401, 403, 405, 407, 409, 411, 413) in a communication system, wherein the network nodes (401, 403, 405, 407, 409, 411, 413) are found in each device with the system, rather than only in the repeaters (101, 103, 105, 107, 109), the site controller (111), or the zone controller (ZC) for the system. The call establishment process is provided as elements (301, 303, 305, 307, 309, 311, 313) of a state machine. Each of the elements (301, 303, 305, 307, 309, 311, 313) is distributed over one or more of the plurality of network nodes (401, 403, 405, 407, 409, 411, 413). If one of the network nodes becomes unavailable, the element(s) supported by the now unavailable network node is reassigned (705, 809), as necessary.

Provision of distributed call handling over a plurality of network nodes

A central networker interface is used to establish inter-operability between a conventional communication system and a trunked communication system. The central networker interface provides the conventional communication system with wireline and RF connections to the trunked communication system. These connections allow each system to share information pertaining to communication units operating within their respective coverage areas.

Method and apparatus of inter-operability between conventional and

A subscriber unit for use with a duplex communication system is described. The present invention contemplates a duplex transceiver which incorporates data and voice handling capablity. A microprocessor generates data and DTMF signalling as well as decoding received data. According to the principles of the present invention, an improved duplex capable subscriber unit is achieved by coupling a microprocessor to a duplex transceiver through switchable filters. The filters exhibit a relatively fast or slow time constant depending on the state of a filter control input. The microprocessor is then capable of operating the subscriber unit with optimum frequency response characteristics depending on whether voice or data is being received. In addition, a summing network coupled between the microprocessor and the transmit switchable filter cooperates with the switchable filter and allows the duplex subscriber unit of the present invention to generate DTMF signalling.

Duplex interconnect dispatch trunked radio

A method of tracking subscribers (201, 203) in a networked radio communications system (100, 200). The subscribers (201,203) are able to roam among a plurality of coverage areas (104-106) which are serviced by a plurality of transmitters (107-109). The transmitters (107-109) are coupled to a central processor (CP, 110), which accesses a memory device (112) for storing subscriber records and site records. Subscriber records include location information for each of the subscribers, while the site records include a logical representation of geographical relationships between the coverage areas. The method relies on the subscriber to send an inbound message (330) which includes its current location. Further, the CP (110) records a message time for the inbound message, producing a timestamped location, then updates (405) a corresponding portion of the subscriber record with the timestamped location.

Method of anticipating a communication unit's location in a networked

In a trunked communication system that supports roaming communication units, communication capabilities in support of the communication activities of the communication unit may be varied from system to system in a controlled manner. This control may be initiated at the instance of the communication unit itself, on a system by system basis (wherein each system maintains a data base and/or retains the capability of contacting a home system for the communication unit), or by a hub that interconnects with each of the trunking systems and which either maintains a data base of preauthorization information or that contacts home systems in order to obtain authorization information.

Trunked communication system with variable communication capability

An apparatus and method for issuing busy call-backs (146) on the voice channel to busied communication units (209,211) on a trunked radio communication system (200) is disclosed. This is accomplished, in part, by issuing a busy signal (104), via a control resource (203), to a communication unit when a requested communication resource is unavailable. Additionally, the radio communication unit (209,211) is capable of receiving the busy signal via the control resource (213) and participating in a second communication while in a busied state. The resource controller (201) is capable of allowing the busied communication unit (209,211) to participate in a second communication on a second communication resource (215) and issuing the call-back signal during the second communication.

Radio communication apparatus and method for voice channel busy call back

A trunked voice/data subscriber is provided that operates in either a voice mode, or one of three data modes. In a first data mode, the voice/data subscriber monitors the voice control channel to enable rapid participation in a voice call. In a second data mode, the subscriber monitors an assigned data channel until either commanded to change modes or until there has been no data activity for a predetermined time interval. Lastly, the subscriber may operate to remain in the last mode used so that, over time, the subscriber resides primarily in the mode predominately used. According to the invention, the voice/data subscriber must request a channel for each voice transmission. However, a data channel request need only be transmitted in no data channels are currently reallocated. If a data channel has been allocated, the subscriber may transmit at any time without first requesting access.

Subscriber unit for a trunked voice/data communication system

A dispatch trunked radio system which provides duplex or simplex telephone interconnect communications to subscriber units is described. The system allows duplex capable trunked system subscriber units to establish a full duplex communication link with conventional land based telephone interconnect service in accordance with a method which unifies the operation of the trunked system subscriber units, a plurality of trunked system repeaters, a trunked system central control unit, and a telephone interconnect control unit. The method of the present invention also provides improved trunked system performance by allowing simultaneous transmission and reception of channel controlling information.
