摘要： A method of routing packets through a fixed source routing communications network from and to mobile units. With this invention an initial access point is determined when a communications session is established to or from a mobile unit through the network. Location information is updated each time the mobile unit moves out of the range of one access point and into the range of another access point of the network. When packets for the session are to be transmitted to the mobile unit from the wired network, the packets are forwarded from the initial access point to a current access point, which by definition is in the range of the mobile unit. When packets for the session are to be transmitted from the mobile unit and to the wired network, the access point intercepts these packets and routes them to their destination and/or initiates route discovery to those destinations. When packets are to be transmitted between mobiles at different access points. The packets are sent between the current access points and not through the home access points.

摘要： In communication systems which include high speed wired local area networks (LANs) and low speed wireless LANs, the bandwidth of the wireless LANs can be severely impacted. It has been found that many broadcast or multicast messages which are forwarded to the wireless LANs are not required as the mobile terminals which would receive the messages are not required to act on them. The present invention provides a means and method to filter out unneeded messages so that they do not impact the bandwidth of the wireless network. Each access point for each wireless LAN maintains a table of parameters for each associated mobile terminal in the connected wireless LAN. The parameters in that table are compared to the parameters in message frames received by the access point and only those messages having parameters found in the table are put on the wireless LAN. The level of filtering can be controlled by specifying which parameters are to be used for filtering messages. The tables at each access point are maintained current by moving table entries from access point to access point as mobile terminals move from wireless LAN to wireless LAN and by removing inactive table entries from the table when a predetermined interval of inactivity is encountered and a terminal is determined to be no longer in active contact with the access point.

摘要： A communications network having a number of routers, a number of base stations and a number of mobile units maintains communications with the mobile units by assigning a unique address known to the routing entities of the network to each mobile unit. By including the mobile units unique address in topology updates of the network, the location of the mobile unit at any time is made known to all routers of the network. That is, once a mobile unit moves into a domain of a new access point and establishes a new link with the new access point, it uses the topology update mechanism of the network to make its new location known to all routers. Once a router of the network receives topology update information specific to the mobile unit's new location, it updates its routing table such that packets destined to the mobile unit are routed in a path which terminates at the mobile unit and contains its new access point.

摘要： The present invention provides shared communication medium capability to the plethora of computer devices, like the PCCAs, that normally are able to communicate with other devices via dedicated point-to-point links, e.g., via the practically universal RS-232 ports. It allows the sharing of the communication medium in a dynamic fashion depending on the instantaneous traffic demands by the various communicating devices. It further allows the emulation of point-to-point links over the shared communications medium in such a way that applications running on a PCCA use the shared medium transparently. Thus, this invention enables applications designed to operate over a point-to-point connection to operate over the shared medium without any modifications of the applications or the point-to-point devices. It enables the shared medium communications and dynamic communication resource allocation by using a device's I/O ports designed for point-to-point communications with dedicated communication resource allocation.

摘要： The present invention provides a method, apparatus and computer product for a mobile device to roam securely and seamlessly from one access point to another access point without disrupting an active PPP connection. The method includes establishing, maintaining, and terminating a PPP connection between a mobile device and a PPP server via an access point, wherein the mobile device is equipped with a serial asynchronous communication interface. The PPP server is attached to a packet switched data network, and the access point is acting as a bridge between the serial communication interface and the packet switched communication interface. Also provided is a method to emulate a direct RS-232 cable connection between a mobile device and another computer located several hops away from the mobile device. It provides a method of keeping the RS-232 cable emulation between the mobile device an another computer system intact despite changes in mobile device's location in the network. It also provides a method of exchanging cookies between peers at the PPP connection establishment time and using them for fast reauthentication. This is a secure method of switching from one PPP proxy to another PPP proxy without disrupting the end to end PPP connection.

摘要： Distributed call setup and rerouting are realized in a mobile-communications network. A connection tree is set up within the network, e.g., upon a mobile user accessing a base station. The connection tree comprises communication routes from a fixed point in the network, the root of the tree, to each base station within a vicinity of the base station accessed by the mobile user. When the mobile user moves from one cell to another within the connection tree, the call is rerouted to another route within the connection tree.

摘要： In a mobile communications network, cell-clusters are defined to include a multiplicity of cells. Wireless connections within the network are classified based on the actions taken for the connections when a radio congestion state is encountered. A cell-cluster controller controls admission of new calls to the cell-cluster, and admits or rejects the calls based on (1) number of existing calls of each class in the cell-cluster, (2) traffic characteristics including call holding time and a hand-off rate of each class, (3) quality-of-service (QOS) requirements of each class, and (4) policy for scheduling or sharing different call classes at each base station of the cell-cluster.
