The likelihood of dropping a call while a User Equipment () is moving quickly from a macrcell (C) into a small cell (B) and then out again because there is insufficient time to set up measurements in the User Equipment, is mitigated by forcing the User Equipment to enter compressed mode as soon as it enters the small cell (B). By immediately forcing the User Equipment to enter compressed mode rather than waiting until it reports that the serving cell is getting weak, it stands a better chance of finding inter-frequency (ie. non-co-channel) and inter-RAT (ie. different radio access technologies) neighboring cells ready to hand out to.

Network elements, wireless communication system and methods therefor

A communication system comprising a core network operably coupled to a small base station (HNB) arranged to support wireless communications to a user equipment UE is described. The HNB comprises a control processor being arranged in a first embodiment to: support setting up of an air interface connection with the UE to allow the UE and the core network to exchange messages, e.g. for a Location Update procedure and to receive an instruction from the core network via a core network connection to release the connection to the core network; usually, the HNB would transmit a RRC Connection Release message to the UE; however, the UE utilizes this situation to request and receive UE measurements by using RRC Measurement Control/Report messages and thus delays the initiation of the RRC Connection Release procedure towards the UE; in a second embodiment, the control processor is arranged to autonomously page the UE: thus, the UE establishes a RRC connection for responding to the paging message and the HNB may request receive UE measurements.

Network element, integrated circuit cellular communication system and method for capturing user equipment measurements

A network element comprises a signal processor supporting communications between a subscriber unit (UE) and a core network (CN). The signal processor is arranged to: receive a first update request message (location or routing area) from the subscriber unit; forward the first update request message to the core network; receive from the CN a first update accept (or response) message; store at least a part of the accept message content; forward the first update response message to the subscriber unit; receive a second update request from the subscriber unit; create a second update accept (or response) message using the at least part of the stored content; and respond to the subscriber unit second update accept (or response) message direct.

Network element, integrated circuit, cellular communication system and method therefor

A communication unit comprises a receiver for receiving radio frequency (RF) signals from at least one wireless serving communication unit, and signal processing logic module arranged to decode information within the received RF signals is the at least one wireless serving communication unit. The signal processing logic module is further arranged to decode transmit power information in a received RF signal from the at least one wireless serving communication unit, and determine from the decoded transmit power information whether a transmission from the at least one wireless serving communication unit is suitable for use as a timing reference. If it is determined that the transmission from the at least one wireless serving communication unit is suitable for use as a timing reference, the communication unit synchronizes an operating frequency to the received RF signal of the at least one wireless serving communication unit.

Communication unit and method for selective frequency synchronization in a cellular communication network

An access point for supporting communication in a femto cell of a cellular communication network. The access point comprises transceiver circuitry arranged to enable communication with at least one cell subscribed wireless communication unit located within the femto cell, and signal processing logic module. The signal processing logic is arranged to configure a transmit power level of a Common Pilot CHannel (CPICH) for transmission based at least on cell subscribed wireless communication unit information.
