摘要： A method for providing a mobile device in a packet data network access to a channelized network is disclosed. At a gateway between the two networks, a first channelized network message that is encapsulated in a first IP data packet from the packet data network is received. The first channelized network message is retrieved and reformatted for sending over the channelized network. The gateway then receives a second channelized network message from the channelized network. An identifier of a mobile device associated with the second channelized network message is retrieved and an IP address for the identified mobile device is determined. Then, the gateway encapsulates the second channelized network message into a second IP data packet and sends the encapsulated second channelized network message to the identified mobile device in the packet data network.

摘要： A wireless communication system 200 comprises a connectionless packet network 201 coupled to a plurality of sites 203-208 that are in location areas 260, 261. The sites join respective location area multicast addresses to receive messages from other sites in their location area. Communication units desiring to participate in talkgroup calls need only to register affiliation with a first site of the location area. Upon the first site receiving an affiliation message, it joins a payload multicast group address to receive payload for the talkgroup. In alternative embodiments, the first site sends, via the location area multicast address, either control message(s) or tunneled payload associated with the talkgroup call to secondary site(s) of the location area. The sites initiate paging sequences to determine whether communication units at their sites desire to participate in the call and, based on the responses, the sites may deliver stored payload and/or join the payload multicast group address to receive payload for the call. In this manner, a centralized entity such as a VLR is not needed to keep track of communication units in the location area.

摘要： In a communications system having at least one service entity and a plurality of endpoints each including a logical entity and a terminal, a method facilitates a session between at least two of the endpoints in the system. The method includes: receiving a first message having information that includes a request for a session between a first endpoint that includes a non-dispatch terminal and at least one other endpoint; detecting that the first endpoint includes a non-dispatch terminal as a function of the first endpoint being unable to perform at least one function; and causing the at least one function to be performed on behalf of the first endpoint by the at least one service entity to facilitate the session between the first endpoint and the at least one other endpoint.

摘要： An information distribution device performs a method for selectively distributing media associated with an incident to a plurality of responders assigned to the incident. The method includes receiving, at the information distribution device, an incident information bundle comprising media inputs associated with the incident. For each responder in the plurality of responders assigned to the incident, the information distribution device: determines a set of roles for the responder; selects a set of filtering templates designed based on the set of roles; applies the set of filtering templates to the information bundle to generate a responder information bundle that includes a subset of the media inputs that is customized to the set of roles for the responder; and delivers the responder information bundle to the responder.

摘要： A wireless communication system 200 comprises a connectionless packet network 201 coupled to a plurality of sites 203–208. Upon a first communication unit (213) initiating a call request for a 2-party call with a second communication unit (215), a call server 235 identifies respective multicast IP addresses (MC1, MC2) associated with the source and target. If the first communication unit 213, or its associated site (205) desires to send payload to the second communication unit 215, it addresses the payload to the multicast IP address (MC2) of the second communication unit, and the second communication unit 215, or its associated site 206 joins the multicast address MC2 to receive the payload. Conversely, if the second communication unit 215, or its associated site (206) desires to send payload to the first communication unit 213, it addresses the payload to the multicast IP address (MC1) of the first communication unit, and the first communication unit 213, or its associated site 205 joins the multicast address MC1 to receive the payload.

摘要： A wireless communication system 200 comprises a connectionless packet network 201 coupled to a plurality of sites 203-208 that are in wireless communication with a plurality of subscriber units 210-217 logically arranged into a plurality of talk groups having corresponding talk group identifications. In one embodiment, each site maintains mappings 220-225 of at least one multicast address to at least one talk group identification. In another embodiment, individual subscriber units maintain such mappings 320. When a subscriber unit affiliates with a given site and talk group (501, 601), the site identifies a multicast address corresponding to the talk group. Based on the multicast address, the site can participate in traffic targeted for the multicast address and, consequently, for the talk group. In this manner, mobility Processing is decentralized, system calability is improved and call setup delays are minimized.

摘要： A body ply splice width monitor is provided to sense the leading and trailing edges of a lateral splice in a web of tire body ply material and to produce an indication upon a monitor as to whether such splice satisfies certain dimensional criteria. A first pair of sensors is maintained along one edge of the web, while a second pair of sensors is maintained along the opposite edge. An encoder tracks the movement of the web through the array of sensors and provides output pulses corresponding to finite dimensional lengths of the web. The number of pulses between the sensed leading edge and sensed trailing edge of the splice is used to indicate and determine the total splice width.

摘要： Method used by a first entity, typically a computer system, on a communication system for assigning itself a unique address known as a network address, which comprises a network number and a node identification number. The entity determines a unique network address for itself within a local subset of entities known as a local area network (LAN). A signal is then transmitted to determine whether a router is connected to the LAN, and if so, to determine if the network number of the address is within a range allowed by the router. If the network number is not within a range allowed by the router, then another network number is selected from a range of numbers provided by the router and another node ID are selected. It is determined whether this value is being used by any other entities in the LAN, and if so, node ID's are selected until an unused network address is ascertained. If all node ID's for an address are checked, then another network number is selected from the range and node ID's are again selected to determine a unique address. Once a unique address is ascertained, this is stored back into a parameter RAM area for a subsequent power up initialization and is used for the unique identification of the first entity.
