A second ontology () is then accessed and at least one first rule associated with the occurrence of the event is obtained from the second ontology () by using at least in part the selected information from the first ontology ().

System and method for knowledge storage in an autonomic network

An apparatus and method is provided for adjusting a Quality of Service (QoS) for a communication device in a communication network. One step includes registering an application from a service provider with the communication device and the communication network. Another step includes receiving, by the communication device, a token from a token provider that permits a modified QoS level for the registered application. Another step includes sending the token by the communication device to the communication network. Another step includes negotiating the QoS level between the service provider and the communication device, dependent at least in part on the reception of the token. Another step includes providing, for the communication device, the modified QoS level permitted by the token for the registered application.

Quality of service modification using a token in a communication network

The disparate data and commands from are received from a managed resource () and have potentially different semantics. The disparate data and commands are processed according to rules received from an autonomic manager () to produce a single normalized view of this information. The actual state of the managed resource is determined from the normalized view of disparate data. The actual state of the managed resource () is compared to a desired state of the managed resource (). When a match does not exist between the actual state and the desired state, a configuration adjustment to the managed resource () and/or another resource is determined to allow the actual state to be the same as the desired state. Then, the configuration adjustment is applied to the managed resource (). When a match exists between the actual state and the desired state, maintenance functions associated with the managed resource () are performed.

Autonomic computing method and apparatus

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

Method and apparatus for performing handoff in a spread-spectrum communication system

A dual-mode mobile station (125) transmits an AMPS signal (Td AMPS) concurrently during transmission of a DS CDMA signal (Td DS CDMA) for purposes of handoff of the mobile station from the DS CDMA system to AMPS. Scanning receivers (221) at surrounding AMPS base-stations (135-138) measure the quality of the AMPS signal (Td AMPS) and determine the best base-station for handoff. To ensure a strong signal during concurrent transmission, other mobile stations not undergoing handoff are instructed to notch their transmissions during transmission by mobile station (125) of the AMPS signal (Td AMPS).

Transmission and reception of signals in a communication systems

Generally stated, a method for performing soft-handoff within a wireless communication system 100 is described herein. The wireless communication system 100 includes, inter alia, a mobile station 104, a first base station 102 in communication with said mobile station via a first communication resource 120, and a second base station 106 with a corresponding second communication resource 130. In a first preferred embodiment, a determination is made that the first communication resource 120 is no longer necessary. The wireless communication system 100 verifies that the second base station 106 has acquired the mobile station 104 via the second communication resource 130. If the second base station 106 has yet to acquire the mobile station 104 on the second communication resource 130, the wireless communication system 100 will override the normal power control mechanisms, increasing the mobile station's 104 transmit power, thereby mitigating the opportunity for an orphan condition to develop.

Power control in a spread-spectrum communication system takes place by determining origination power of a traffic channel based on a number of active demodulators and pilot channel signal quality (610). Once origination transmit power is determined and call origination takes place, the transmit power is reduced at a first rate when a time is less than a time for all active demodulators to be established (615), otherwise the transmit power is reduced at a second rate (621). After all active demodulators have been acquired power control takes place by receiving a Power Measurement Report Message (PMRM) or a Pilot Strength Measurement Message (PSMM), determining, a signal quality metric existing at the remote unit based on the PMRM or PSMM, and adjusting transmit power based on the signal quality metric (645).

A method of communication handover from a first communication entity (33) to a second communication entity (43) in a communication system (10) where a communication unit (80), communicating with a transceiver (23) associated with the second communication entity, is linked to the first communication entity. The invention provides for establishing a communication link between the communication unit and the second communication entity while maintaining a communication link between the communication unit and the first communication entitiy. Then, communications are substantially simultaneously transfered to the second communication entity while terminated from the first communication entity.

Method and apparatus communication handover in a communication system

A communication system (100) employs a method (400) and apparatus (101, 113) for mitigating interference (119) produced by a communication unit (113) communicating with a serving base site (101) in the communication system (100). While the communication unit (113) is communicating with the serving base site (101), the communication unit (113) monitors (405) a downlink communication signal (118) transmitted by an alternate base site (105). The communication unit (113) then determines (407) an indicia of signal usability for the monitored downlink signal (118) and adjusts (421) a transmit power of the communication unit (113) based on the indicia of signal usability.

A method of reducing an audio gap in a signal connection with a communication unit during handoff in a cellular communication system is provided. The method includes the steps of providing a temporary signal connection with the communication unit from a mobile switching center (MSC) of a source base site, through the source base site to a handoff target base site and establishing a trunk connection from the MSC of the source base site to a MSC of the target base site. The method further includes the step of interconnecting, at the target base site, the temporary signal connection, trunk connection, and communication unit; and re-routing the signal connection with the communication unit through the trunk connection.

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 theshold, 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.

Method of selecting a handoff target in a cellular communication system

A method of selecting handover targets for a communication unit exchanging a communicated signal through a serving base site in a digital cellular system. The method uses timing advance to determine a relative distance of a communication unit to the serving base site. The method comprising 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 non-adjacent base sites may be determined from the directionality of the communication unit. The method further includes the step of selecting a handover target providing a highest relative RSSI value to the communication unit from the modified base site frequency list.

An AMPS system facilitates reception and processing of a DS CDMA signal transmitted by a mobile station (125). The AMPS system provides an alternate path for the signal to be received by a DS CDMA receiver (506) system. The DS CDMA receiver system generates a signal compatible with the AMPS system, adjusts the generated signal to be proportional to the DS CDMA signal, and inputs the adjusted signal (510) into the AMPS system. The AMPS system then processes the adjusted signal for purposes of handoff of the mobile station (125) from the DS CDMA system to the AMPS system.

Signal processing in communication systems

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.
