A method of updating Global Positioning System almanac data includes steps for obtaining a current satellite almanac for a satellite constellation at a server in a communications infrastructure associated with a wireless device (), creating a subset of the current satellite almanac in the server that includes satellite almanac data only for fewer than all satellites listed in the current satellite almanac (), and transmitting the subset of the current satellite almanac from the server to the wireless device ().

A method for setting up a dynamic group call includes the step () of selecting a group of radios () by a dynamic group call originator (). Once the radios that will be part of the dynamic group have been selected, the dynamic group call originator () transmits a dynamic group call message(s) to each of the selected radios. Each of the transmitted dynamic group call message(s) includes the IP address of one of the selected radios. Upon each of the target radios receiving their individually directed message, the target radios () can each send an optional acknowledgment message to the dynamic group call originator (). The originator () and the target radios () then switch to the dynamic talk group number assigned by the dynamic talk group message. Once the dynamic talk group call has been completed, the originator of the dynamic group call can send a dynamic group call disconnect message, which once received by the target radios () causes them to revert back to their previous operational state. Alternatively, instead of the dynamic talk group originator transmitting a disconnect message, the radio communication system controller () can transmit a disconnect message such as based on a timer (e.g., hangtimer, etc.).

Method for dynamically configuring group calls in a radio system

A subscriber unit (,) operating within a radio communication system (,) supplements neighbor list information received from a cell site (,), when that cell site (,) is expected to provide inadequate neighbor cell list information. When the subscriber unit (,) obtains a new neighbor cell list (,) from the cell site (,), it determines whether characteristics of the cell site (,) is such that the new neighbor cell list (,) does not adequately reflect available neighboring cell sites. Such a condition is presumed to exist for a cell site designated as a high site. In such cases, the subscriber unit combines entries from its current neighbor cell list (,) with entries from the new neighbor cell list (,) obtained from the cell site to generate a supplemented neighbor cell list (,). The supplemented neighbor cell list (,) is used to monitor potential server sites, and to make hand-over decisions.

A radio communication system (100) employs a method for setting an output power of a base site (e.g., 107) in the system. The radio communication system includes at least two base sites (101-107) and a communication path (109, 131-137) coupling the base sites together. A first base site (e.g., 107) transmits a signal (147) via a radio communication resource. A second base site (e.g., 101) receives the signal and determines a signal quality metric of the received signal. Upon determining the signal quality metric, the second base site generates and conveys a message to the first base site via the communication path, wherein the message instructs the first base site to adjust an output power of the first base site. The first base site then adjusts its output power responsive to the message.

A communication system (101) provides a subscriber unit (105) with access to an information network (130) through gateway equipment (110) that is coupled to a network server (120). The subscriber unit (105) transmits to the gateway equipment (110) a request for data from the information network (130). The gateway equipment (110) communicates the request in a message to the network server (120), the message including an identifier for the originating subscriber unit. The network server (120) retrieves data corresponding to the request from the information network (130), and conveys this data to the subscriber unit (105) using the identifier. Preferably, the network server (120) communicates with the subscriber unit (105) via a message service (140) that provides external access to the communication system (101).
