    Abstract: In a closed-loop communication system, a base station (14, 16a, 16b) exchanges signals with both fixed location (18) and mobile user (12) stations. When a user or subscriber initially registers with the base station (14, 16a, 16b), the base station determines a status of this subscriber based on, for example, an electronic serial number transmitted to the base station. The base station compares the electronic serial number to a database (Home Location Register) (15) which determines whether the user corresponds to a fixed station (18) or a mobile station (12). If the user is a fixed station, then the base station (14, 16a, 16b) lowers nominal and minimum power level thresholds. Based on the lowered thresholds, the base station thereafter transmits forward link signals to the fixed station (18) at a lower power level. As a result, the base station can increase its capacity due to the lower overall power rate.

    Abstract: In a communications network, a network user communicates using a remote unit (125) with another user (30) via at least one base station (B1A). The network is comprised of first (MSC-I) and second (MSC-II) mobile switching control stations respectively controlling communications through a first set of base stations (B1A-B1E) including a first base station (B1A) and through a second set of base stations (B2A-B2E) including a second base station (B2A). To direct communications between the remote unit (125) and the first (B1A) and second base stations (B2A) the first base station (B1A) measures a round trip delay of an active communication signal between the first base station (B1A) and the remote unit (125). The remote unit (125) measures a first phase offset of a pilot signal received from a first candidate base station (B1A) and reports it to the first mobile switching center (MSC-I) via the first base station (B1A). The first mobile switching center (MSC-I) calculates a candidate round trip delay between the remote unit (125) and the first candidate base station (B1A) based on the first phase offset and the round trip delay of the active communication signal. An active communication control unit accesses a measurement directed hard handoff table to determine a location of the remote unit based on the round trip delay corresponding to the first active communication signal and the candidate round trip delay.

    Abstract: A novel and improved method and apparatus for performing an inter-system soft handoff is described. In accordance with the present invention, when a subscriber unit crosses from a first cellular system to a second cellular system, a base station controller (20) determines if sufficient network resources are available to conduct an inter-system soft handoff. If so, the base station controller (20) generates a set of signaling messages that cause a call processing resource to be allocated, and for the call to be processed at the second cellular system. The base station controller (20) then perform data-selection and data-broadcast for the call by transmitting data to the subscriber unit (28) by way of the second cellular system as well as via one or more base stations to which the base station controller (20) is directly coupled. The determination as to whether sufficient network resources are available to conduct the inter-system soft handoff is based on the type of connection that exists between the first cellular system and the second cellular system, the number of inter-system calls being conducted, and the frame offset of the call currently being processed.

    Abstract: A method of designing a network results in a network with an efficient addressing scheme which allows for filters to perform a simple logical operation. The process begins by arranging a plurality of nodes connected by a plurality of bi-directional links in a tree topology. Each node is assigned a range of consecutive flow process addresses such that each packet carried in a first direction on one of the bi-directional links has an address within the range A A .

    Abstract: The cellular communication system includes a number of base stations through which a mobile unit communicates. The mobile unit maintains a list of active base stations with which it can communicate. One of the active stations is in communication with the mobile and uses this communication to measure the round-trip-delay between mobile and station. This delay is compared with a threshold and if this is exceeded, and the base station is a boundary station, then a hard hand-off is executed. The mobile can also monitor candidate base stations and if a triggering pilot signal is detected a hand-off can be triggered. Preferably the handoff can be between base stations controlled by different mobile switching centres.
