Disclosed herein is a handover method and apparatus for providing mobile Internet Protocol Television (IPTV) service over wireless communication networks. The handover method includes checking whether the strength of a signal received from a first base station of a serving first wireless network falls within a predetermined first threshold range; if the strength of the signal falls within the range, checking whether the strength of a signal received from at least one base station of a second wireless network is higher than a second threshold value required for handover; estimating the velocity and direction of a Mobile Node (MN) using location information received from a satellite; predicting a handover target base station using the estimated velocity and estimated location information; and, if the predicted target base station is one of base stations having the second threshold value, performing handover to the target base station.

A method of facilitating identification of a user equipment (UE) is disclosed. A first network control node (NCN) receives an radio link failure (RLF) indication message including a first mobile identity indicator (MII) of a UE. The first NCN determines a second MII of the UE, the second MII being associated with the first MII, and a second NCN associated with the second MII. And the first NCN sends the second MII to the second NCN.

The present application discloses a measurement control method, a user equipment, a control node, and a system, relates to the field of wireless communications, and can reduce handover signaling and improve a handover success rate. The method of the present application mainly includes: receiving measurement configuration information sent by a control node, where the measurement configuration information includes a list of first-type cells, the type of first-type cells, a list of second-type cells, the type of second-type cells, hierarchical cell structure (HCS) priorities, a frequency of first-type cells, or a dedicated parameter for evaluating an event trigger threshold; detecting cell signal quality or signal strength of a cell; and determining, according to the cell signal quality or signal strength and the measurement configuration information, whether to report an event or a measurement result to the control node. The present application is mainly used in a process of mobility management.

A method for transmitting a mobility state is provided in the present invention, the method includes: when an source evolved NodeB (eNB) performs a handover of a user equipment (UE) in a connectivity state, it sends the UE historical information to a target eNB; the target eNB decides a mobility state of the UE according to the UE historical information. Alternatively, when the source eNB performs a handover of the UE in a connectivity state, it decides the mobility state of the UE according to the UE historical information, sets the corresponding mobility state instruction information and sends it to the target eNB; the target eNB acquires the mobility state corresponding to the UE according to the received mobility state instruction information. A system for transmitting a mobility state is also provided in the present invention.

An apparatus and method for handover in a wireless communication system are provided. The method includes, upon handover execution, estimating a channel, controlling a transmission power of a Mobile Station (MS) depending on the channel estimation result, and transmitting a handover message using the controlled transmission power.

The present disclosure relates to a pre-5^th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4^th-Generation (4G) communication system such as Long Term Evolution (LTE). According to embodiments, a method performed by a user equipment (UE) in a wireless communication system, the method comprises: receiving, from a base station, a radio resource control (RRC) reconfiguration message including conditional configuration information, wherein the conditional configuration information includes: identification information for a candidate cell; and a configuration of the candidate cell; and performing one or more operations for a conditional handover based on RRC reconfiguration message.
