摘要： A cellular network includes a control station and a network of base stations installed one per cell with which one or more mobile stations can communicate as they roam through a cell. Redundantly deployed spare base stations are introduced along with the primary base station at a central area of each cell. The redundantly deployed spare base stations handle new calls when the associated primary base station is overloaded, participate in retransmission of data lost due to degraded channel conditions and congestion in the network, and assist in handoffs. Primary and spare satellite stations are deployed in regions marked by hills or valleys to augment the communicative capabilities of the primary and spare base stations.

摘要： In a widely distributed digital communication network call delays and eventual outcome are anticipated (i.e., expected call outcome) at the initiation of a call at an originating terminal and the call is completed by signal switching to its destination terminal and by decreasing the number of related message transfers between network controllers and hubs required to complete the balance of administrative refinements of the call connection. The routing steps for setting up the call trajectory to the destination hub are completed immediately before the administrative steps, such as authentication, access control, bandwidth availability etc., are performed. Administrative refinements subsequent to the preliminary call set up are performed in a distributive manner. Administrative and capacity items are determined and completed post route determination and computed or accessed in parallel making this information available for a final call set up. If this information is adverse the call is immediately terminated. In one aspect the processors for administrative and capacity determination are connected in a parallel manner and work concurrently.

摘要： Intelligent allocation of wireless resources can help avoid the problems of dropped calls in a mobile communications network. A service for allocating resources is designed to develop profiles of subscribers' mobility. That is, profiles are developed for routes, traveled by subscribers at certain days and times. For example, some subscribers commute to and from work at relatively fixed times. By compiling this information in the profile and tracking the movement of the subscriber, the mobile network can anticipate the subscriber's movement into a next cell. Thus, wireless resources in the next cell can be reserved prior to the anticipated handover of an ongoing call involving the subscriber. Thus, uninterrupted service can be maintained and dropped calls can be avoided.

摘要： The approximate position of a mobile station in a cell can be predicted by measuring the signal strength between the mobile station and the base station of the cell in which it is located and the base stations of the neighboring cells. After a series of instantaneous signal strength measurements have been collected, the velocity and direction of the mobile unit can be determined. Based on the velocity and direction of the mobile unit, future locations of the mobile unit can be predicted including the projected signal strength between the mobile station and the base stations of the cell in which it is located and neighboring cells. Analyzing the projected signal strength values, the time when the mobile unit will require handover to a neighboring cell can be determined and if desired, resources in a neighboring cell can be allocated in anticipation of the mobile unit being handed over to that cell. New signal strength measurements are periodically collected and new projections are made to increase the accuracy of the estimate of when handover will occur and to what neighboring cell.

摘要： A method for conveying signaling information of a communication system that uses MIMO antenna systems. To enable a relatively larger amount of information to be conveyed over the communication system and thus exploit the use of the MIMO antenna system, forward link signaling channels are provided where such channels contain swapping information that allow the communication system to retransmit traffic information using any one of the antenna elements of a MIMO system. The forward link signaling channels also contain channel assignment information that indicate which particular groups of channels are available for use by particular users of the communication system. To further accommodate for the relatively larger amount of information being conveyed over the communication system, the format of the reverse link signaling information is modified using any one or any combination of the following three mechanisms: (1) reverse signaling link information is time division multiplexed; (2) the reverse link information is modulated at relatively higher order modulation; (3) additional channels are provided for the reverse link information.
