  • Patent number: 6229793
    Abstract: A unique byte is used to bookend commands and data for the purpose of allowing inband signalling and command communication between the IWF and the BSC portions of a mobile communication system having DS0 maximum data rate transfer capability per data channel. The receipt of two consecutive ones of the unique bytes indicates that the next 2 bytes will be a command. The receipt of 3 consecutive ones of the unique bytes indicates the next byte will be data. This inband signalling and data transfer allows the IWF functionality to be remote from the main switch used by a given BSC. The CDMA system uses the inband signals to pass a plurality of data packets in parallel on DS0 capacity channel links through the MTX in a half-duplex burst whenever a data buffer within the IWF or a connected high data transfer rate mobile station is filled to a given level. This burst process may operate on a time multiplex basis with low speed data transfers using the same DS0 links to communicate with the IWF.

  • Patent number: 6224477
    Abstract: A method for ordering subscriber records in a location database stored in at least one of a Visitor Location Register (VLR) or a Home Location Register (HLR) of a wireless communications network by ordering the subscriber records in subsets according to the access rates of the records. Records within the respective subsets are then ordered in a middle-rootage order based on the subscriber ID of each subscriber record. The subscriber records are then inserted into a binary tree in subset order beginning with the subset containing subscriber records having the highest access rate. This method enables subscriber records to be more economically stored and used than is possible using conventional binary trees and, thereby, increases network capacity.

  • Patent number: 6181927
    Abstract: In a telecommunications system, a subscriber station invokes a sponsored-call application service program when the subscriber station originates a call. Based upon certain criteria, service logic determines whether the call is sponsored or not. If sponsored, additional service logic utilizes the location of the call origination (i.e., location of the subscriber station) and/or other attributes of the subscriber station to select an announcement from a plurality of announcements for transmission to the subscriber station. After the announcement is transmitted (i.e., played), the subscriber station is connected to the call's desired destination. If not sponsored, the call is handled as a normal call.

  • Patent number: 6151512
    Abstract: A configuration of base stations and sectors within cells of a CDMA wireless communication network provide greater call handling capacity. By optimally configuring sectors of a cell controlled by multiple base stations, fewer channel elements are required to implement the desired service and a resultant system has improved signal demodulation, lower power requirements, improved performance, and lower cost for a service provider. The base stations are configured to support "N" sectored cells to ensure that each cell has a maximum amount of capacity for all mobile users therein. This method involves configuring the sectors serviced by a same base station adjacent to one another. By configuring the sectors associated with base stations in this manner, there are fewer instances of soft handoff and more instances of softer handoff. Furthermore, configuring the sectors to be adjacent to one another ensures optimal power collection by each of the sectors during the communication process.

  • Patent number: 6138007
    Abstract: Disclosed is an apparatus for and a method of providing late call forwarding when a dual mode GSM/IS41 type mobile station has roamed from its home GSM network to a North American IS41 type cellular network. The GSM network functionally supports the GSM Optimal Routing technical specification whereby the address of the gateway GSM MSC is supplied to the interconnected IWU. When the IWU receives a redirect request from the terminating IS41 MSC (MTSO) upon failure to connect to the roaring MS, the IWU tells the GSM originating gateway MSC to resume call handling. The originating gateway MSC then completes the late call forwarding process using the call forwarding number as a forwarding address.
