摘要： A method, information processing system, and wireless communication system that selects a set of network paths for transmitting data to a serving network. The method first determines (404) that there is data to transmit to the serving network (102). For each of a plurality of base stations (106, 107, 108), an assessment of at least one traffic engineering parameter associated with each of the base stations (106, 107, 108) is performed (406). A set of base stations in which the traffic engineering parameters satisfy predetermined communication criteria associated with the wireless device (104) is selected (408) in response to performing the assessment. The selected set of base stations is used to transmit wireless device data to the serving network.

摘要： Various embodiments are described to enable multiple, independent communication networks to share in an autonomous and dynamic manner unlicensed wireless resources. Generally, this involves determining that a first network node (122) is using at least a portion of a wireless resource to provide network service to at least one remote unit (102). A second network node (123), under the control of a different network operator than the first node and desiring to use the wireless resource, sends the first network node, a request to relinquish use of at least a portion of the wireless resource. The second network node sends this request wirelessly, perhaps using the wireless resource itself. If the first network node grants the request, the second node may then begin using at least a portion of the relinquished resource to provide network service.

摘要： A communications network (20) includes any number of moving switching nodes (30) and a route-determining node (28). The route-determining node (28) performs an off-line procedure (58) to define a-priori routing for the entire network. This procedure (58) is performed repetitively to track switching node (30) movement and to define routing for numerous epochs included in a planning period. The procedure (58) includes a process (86) for determining all shortest path routes between all possible origination and destination switching nodes (30). Another process (84) matches predicted call traffic for a subject epoch with the shortest path routes. Another process (88) generates routing code tables (54) in response to the predicted call traffic matched to shortest path routes. This process (88) assigns logical routing IDs (52) to physically distinct, shortest path routes in proportion to the predicted call traffic allocated to the distinct routes.

摘要： A method of solving a constraint-satisfaction problem with a data processor includes the steps of (a) providing a search tree structure (10) representing a plurality (N) of variables (X), the search tree structure having a plurality of levels; (b) searching (L) shallow levels of the search tree structure by employing a backtrack search method wherein (L) is less than or equal to a specified value H; and (c) searching (M) remaining, deeper, levels of the search tree structure by employing a lookahead search method. The step of searching (L) shallow levels of the search tree structure includes a step of binding a set of X.sub.1 through X.sub.H variables each to an element from its domain such that no constraints are violated.

摘要： A system for distributing bandwidth in a mesh network includes a first access point (AP1) that determines an amount of data to be sent from the first access point to the second access point (AP2) and receives a value indicating an amount of data to be received from the second access point. The first access point (AP1) then determines a percentage of a frame (I) to be used to send the data from the first access point to the second access point by multiplying the total data-carrying portion (206, 210) of the frame (I) by the amount of data to be sent from the first access point to the second access point divided by the sum of the amount of data to be sent from the first access point to the second access point and the amount of data to be received from the second access point.

摘要： A method and apparatus includes a scheduling entity (308) for scheduling and transmitting the superframe (402) across a communication network (200). The controller (310) coupled with scheduling entity (308) groups the subscriber unit (304) into one of the plurality of groups. The scheduler entity (308) assigns a coding scheme for each group and encodes each frame of the superframe (402) based upon the assigned coding scheme for the group, to which the frame is to be transmitted. The transceiver (316) coupled with controller (310) via hardware interface (314) receives the encoded superframe and transmits the superframe to the plurality of subscriber units in the communication network (200).

摘要： A communication network (20) includes a multiplicity of switching nodes (18), many of which are located in orbiting satellites (16). Communication links (30) interconnect the switching nodes (18). A control center (32) performs a request for connection process (40) which routes a new call request over a current internodal topology of links (35) if possible. If the new call request cannot be routed over the current internodal topology of links (35), the process (40) determines how to augment the network with the creation of new links (45) so that the new call can be routed. As calls terminate, unused links are taken out of service.

摘要： The call admission control method provides guaranteed bandwidth connections in a mobile telecommunication networks (10) that have varying topology and dynamic capacities. Method (100) provides a systematic way to decide when to admit connection requests in a low-earth or medium-earth orbit based satellite telecommunication system (10). A call admission controller, located in a ground control station (40) receives a connection request from an earth station (50) that may be forwarded from a satellite (21) in a constellation (20) of satellites. The call admission controller segments a call holding time into a sequence of time segments and determines whether a path exists through the network (10) that has the required minimum bandwidth for each of the time segments. If such a path exists, the connection request is admitted and the call goes through. Otherwise, the call is denied and communication is blocked.

摘要： System (10) and methods (100) assign satellite link access bandwidth upon demand as requested by a number of subscriber units (30). After receiving the connection request, a number of time slots being requested is determined. Next, if the maximum number of available time slots is greater than or equal to the number of time slots being requested plus the number of time slots already in use, the connection request is accepted and the number of requested time slots are allocated before communication begins. Otherwise the connection request is rejected and the subscriber unit (30) must try later.
