A base station relates to a wireless communication system that performs handover from a cell connected with a terminal to a neighbor cell of the cell. The base station includes: circuitry, which, in operation, sets an offset to be applied to reception quality of the neighbor cell according to a quality of service (QoS) class identifier (QCI) of the terminal when the terminal determines whether to report a measurement result to be used in determination on the handover; and a transmitter, which, in operation, transmits the offset to the terminal.

The present invention relates to a handover method and apparatus in a wireless communication system supporting an eICIC function. A communication method of a first base station in a heterogeneous network wireless communication system, which includes the first base station and a second base station and supports a cell range expansion (CRE) function, comprises the steps of: monitoring whether the cell range expansion function is deactivated; when the deactivation of the cell range expansion function is detected, generating a handover request message; and transmitting the handover request message to the second base station.

A system and related method for increasing or decreasing the range of a pico cell station. The system and method determine triggers for dynamic range change, measure operational conditions and make a change reactive to operational conditions. Range increase may be implemented to address a coverage hole. Range decrease may be implemented to address holdover attempts. Range changes are implemented by changing transmission power, reference signal received power and/or cell reselection thresholds.

This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for limiting handoffs in cellular networks. In some aspects, a user equipment (UE) may determine a quantity of handoffs that are performed between two or more radio access technologies (RATs) during a time period. The UE may determine whether the quantity of handoffs exceeds a handoff threshold within the time period. The UE may reduce a rate of handoffs when the UE determines that the quantity of handoffs exceeds the handoff threshold within the time period. The UE also may select one of the RATs to camp on and maintain the wireless connection when the UE determines that the quantity of handoffs exceeds the handoff threshold. The UE may determine which RAT to camp on based on handoff count information, handoff total connection time information, or contextual awareness information.

A server device of the invention prevents congestion in a wireless network due to an excessive number of accesses. The behavior analysis server device includes a behavior analysis unit which analyzes data packets of each mobile terminal connected to the wireless network within a predetermined analysis time and generates information indicating communication behavior as communication behavior information; a recording unit which records the communication behavior information; and a type determination unit which determines whether the communication behavior information satisfies a predetermined behavior type determination condition, and transmits a notification for connecting, a mobile terminal that has performed a communication associated with the communication behavior information satisfying the predetermined behavior type determination condition, to a predetermined cell.
