摘要:
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.
摘要:
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.

The disparate data and commands from are received from a managed resource (102) and have potentially different semantics. The disparate data and commands are processed according to rules received from an autonomic manager (112) 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 (102) is compared to a desired state of the managed resource (102). When a match does not exist between the actual state and the desired state, a configuration adjustment to the managed resource (102) 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 (102). When a match exists between the actual state and the desired state, maintenance functions associated with the managed resource (102) are performed.
摘要:
An indication of an occurrence of an event is received. A first ontology (124) is accessed and selected information associated with the occurrence of the event is obtained from the first ontology (124). A second ontology (122) is then accessed and at least one first rule associated with the occurrence of the event is obtained from the second ontology (122) by using at least in part the selected information from the first ontology (124).
摘要:
A base station 106 is provided that has a transceiver 202 that transmits and receives data. The transceiver is coupled to a controller 204. To configure the base station, the transceiver sends an identifier 210 that is associated with the base station together with information regarding the installation of the base station in the communication to the network to access parameters 306 from a database 304 for the base station. The parameters can be based on data known from the purchase of the base station, the location of the base station within the communication network and planning data for the communication network.

A method and system for optimizing a Quality of Service (QoS) for an application is provided. The method comprises generating (205) a dynamic database (110 or 150) of statistical information regarding at least one of the applications and one or more communication network (115, 120 and 125). Further, the method comprises selecting (210) the application to operate on the communication network. The dynamic database is then analyzed (215) to determine at least one network configuration based on desired QoS requirement. Based on the analysis of at least one network configuration a connection (220) is made to the requested application.
摘要:
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).
摘要:
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.
摘要:
A method and apparatus for determining which sector antenna of a sectorized cellular radiotelephone system is receiving the strongest radio signal is disclosed. The signal strength of sector antennas is sequentially sampled, converted to digital representations, and stored according to which antenna received the signal. The digital representations are recalled from storage and the strongest signal along with an identification of the receiving antenna are determined. This determination may be used in the handoff process or in detecting when a remote unit requires a handoff.

A fixed site station for cellular systems is disclosed. A plurality of radio transceivers are removably disposed in apertures of the common equipment housing and are provided unique parameters of operation by the system controller dependent upon the aperture in which the transceiver is located and the antenna configuration of the cell being served.
