    Abstract: 2136543 9400927 PCTABS00030 A base-site (109) communicating to a mobile (108) increases the power level of a transmission of a handoff command when required. The base-site (109) detects when handoff is required, and transmits the handoff command at a first power level (P1) which is essentially equal to the power level of the base-site (109) to mobile (108) voice communication power level. If the handoff command does not reach mobile (108), either after the elapse of a predetermined time period or some other predetermined triggering event, base-site (109) transmits the handoff command at a second, increased power level (P2).

    Abstract: A method is offered of achieving a desired C/I ratio within a cellular system, at reduced transmitter power levels, by measuring a signal loss on a downlink between a base site transmitter (31) and mobile receiver (20) and calculating an uplink signal magnitude at a base site receiver. A communication channel is then selected from a number of communication channels based upon comparison of the uplink signal magnitude with pre-measured interference levels for each channel of the number of channels to produce a desired C/I ratio.

    Abstract: A method of selecting handover targets for a communication unit (40) exchanging a communicated signal through a serving base site (10-19) in a digital cellular system. The method uses timing advance to determine a relative distance of a communication unit (40) to the serving base site (10-19). The method comprises the steps of comparing a timing advance value with a first threshold. The first threshold may be equal to a distance one and one-half times the radius of the serving cell. When the timing advance value exceeds the first threshold, a base site frequency list is modified to include base sites non-adjacent the serving base site. The identity of the base sites non-adjacent the serving base sites may be determined from the directionality of communication unit (40). The method further includes the step of selecting a handover target providing highest relative RRSI value to the communication unit (40) from the modified base site frequency list.

    Abstract: In a cellular radio-telephone system (50), a method of selecting an appropriate handoff target where the timing advance of a mobile has exceeded a timing advance threshold, the bit error rate has risen above a BER threshold, or the signal level has fallen below an RSSI threshold. The method includes discarding signal measurements of inappropriate base sites or base sites at excessive distance and performing calculations on the remaining measurements to select an appropriate handoff target.

    Abstract: A method and apparatus for providing a service from an application service provider to a client in a communications system including a network proxy describes a first step of defining services provided by the service provider as Extensible Markup Language (XML) metadata. A next step includes defining services desired by the client as XML metadata. A next step includes collecting the XML metadata from the client and service provider. A next step includes comparing the client XML metadata against the service provider XML metadata. A next step includes providing the substantially matched service from the service provider to the client upon the finding of a substantial match between the client metadata and the service provider metadata.

    Abstract: Handoff from a Code-Division, Multiple Access (CDMA) protocol to an Advanced Mobile Phone Service (AMPS) protocol occurs by comparing a remote unit's (405) phase shift measurement to a threshold (503) and determining a reference CDMA base station (401) from an active set of CDMA base stations (515). Next, corrected phase shifts are calculated for each CDMA base station in the active set (521) and the remote unit (405) is handed off to an AMPS base station (109) underlying the CDMA coverage area (126) having the smallest corrected phase shift (525).
