Abstract: A method and apparatus for passing network device operations between a source and a target network device which are associated with a mobile communication unit in a radio communication system is provided. This passing of network device operations is accomplished by converting a first form of information to a second form in the source network device. Subsequently, the source and the target network device are notified that operations associated with the mobile communication unit will be passed at a particular time. At that particular time the information converting is bypassed such that the first form of information is provided to the target network device. In addition, the target network device begins to monitor incoming information for the first form of incoming information. In response to a presence of the first form of incoming information at the target network device, the first form of information is converted into the second form in the target network device.

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 of each channel of the number of channels to produce a desired C/I ratio.

Abstract: A method for handover in a cellular system is provided which includes periodically scanning (100) from neighboring cells, traffic channels of a serving cell to determine channel metrics. If the channel metrics exceed a threshold (102), validating the serving cell identity (104) by verifying traffic channel color code. The channel metrics are then periodically transferred (108) to the serving cell where a handover decision is made.

Abstract: The method consists of analyzing a handoff request received from a source base station at a source base site controller (BSC). If the handoff request contains a preferred base site list (is from a MAHO environment) the request is forwarded to the mobile switching center. If the handoff request does not contain the preferred list, the BSC generates a candidate list and transmits measurement messages to each candidate base site. The candidate base sites take measurements and reply to the BSC. The BSC uses the replies to generate a preferred base site list which is forwarded to the MSC. When the MSC receives a preferred base site list, it selects a handoff base site and executes the handoff.

Abstract: 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.

Abstract: A communication system (100) is provided that comprises an overlay communication system and an underlay ad-hoc communication system. Route discovery in the ad-hoc communication system takes place by notifying the overlay communication system of the source and destination nodes. The overlay communication system instructs all base stations between the source and destination nodes to instruct all nodes to participate in route discovery.
