  • Patent number: 6377808
    Abstract: A controller in a communication device receives a request, from a process operating in the communication device, to subscribe to a data routing service that is managed by the controller. In response to the request, the controller assigns a destination identifier to the process and adds the process and the assigned destination identifier to a routing table that is stored in a memory associated with the controller. Data subsequently received from a data source is routed to the process or to one of multiple communication ports by the controller by reference to the destination identifier, or the absence of a destination identifier, stored in the routing table.

  • Patent number: 6363249
    Abstract: A wireless message communication system (11) delivers dynamically configurable datagram messages between a server (15) and subscriber units (17, 18, 19, 20, 21, 22). The server (15) queries a subscriber unit (17) for its data capability profile, such as supported data types, number of data fields, size of each data field, and data type for each data field. The server (15) and the subscriber unit (17) dynamically configure a message datagram (200) to conform message information in transmitted data to the data capability profile of the subscriber unit (17). The server (15) and the subscriber unit (17) then wirelessly communicate a message containing message data packets arranged and formatted according to the message datagram (200).

  • Patent number: 6181946
    Abstract: A subscriber (410) to a radio communication system manages information needed to monitor for potential server sites during an ongoing communication session. Upon switching server sites during an ongoing communication (520, 530, 540, 550), the subscriber uses a modified neighbor site list for subsequent monitoring for potential server sites (570). The modified list is generated from the original list without benefit of new information downloaded from an external source, by replacing information representing the new server site with information representing the old server site (560).

  • Patent number: 5987332
    Abstract: A subscriber (510) to a radio communication system acquires new neighbor cell information after switching to a new server site (530) during lulls in an ongoing communication session. In one embodiment, the new server site (530) broadcasts neighbor cell list information during lulls in the communication activity on the communication channel in an unsolicited manner (710, 720). In an alternative embodiment, the subscriber (510) first transmits a request to the server site for neighbor cell list information during a lull in communication activity (810, 820). The server site (530) responds by transmitting neighbor cell list information during one or more lulls in communication activity on the communication channel (830, 840).
