A method of changing the serving cell in a cellular communications network is provided. A radio communications link is established between a serving network node of a serving cell and a mobile terminal. The mobile terminal sends radio measurement reports for cells other than the serving cell. Once a predetermined condition has been fulfilled, a pre-configuration is performed to establish a radio communications link for one or more cells being a candidate for a new serving cell.

A method and apparatus are provided for enabling a UE to perform accurate and efficient cell reselection in a cellular mobile communications system. If reselection to the same cell is repeated, the UE releases itself from a high-speed UE state or excludes the number of reselections to the same cell from the number of cell changes counted for a duration set for deciding as to the high-speed UE state, according to a ping-pong duration threshold and a ping-pong occurrence number threshold. The UE uses a non-scaled down cell reselection time limit in a non-high-speed UE state, and a scaled-down cell reselection time limit in the high-speed UE state. Thus, the UE reselects to a non-serving cell having the highest ranking continuously for the cell reselection time limit.

A user equipment (UE) is provide which reduces uplink signaling overhead in the process of reporting inter-frequency measurement results over a RACH. For measurement reporting, the UE receives an SIB including a cell information list for non-used frequency cells and a threshold from an RNC, compares signal strengths of signals received from the non-used frequency cells with the threshold, and acquires at least one inter-frequency cell ID indicating at least one non-used frequency cell having signal strength exceeding the threshold from the cell information list. The at least one inter-frequency cell ID is included in a RACH message as measurement result information for the at least one non-used frequency cell, and transmitted to the RNC. The RNC determines that the cell corresponding to the inter-frequency cell ID has signal strength exceeding the threshold.

A method and apparatus is provided for signaling network sharing information about neighbor cells in an NS system where a RAN is shared among a plurality of CN operators. In the signaling method, it is determined whether each of neighbor cells of a current cell in which a UE is located, is shared by a CN operator other than a CN operator controlling the neighbor cell. System information without network sharing information is generated if at least one of the neighbor cells is shared by a CN operator other than a CN operator controlling the neighbor cell. System information including the network sharing information is generated if none of the neighbor cells are shared by any CN operator other than CN operators controlling the neighbor cells. The system information is then broadcast to the UE from the current cell.

A method and apparatus for selecting the PL of an interested MBMS service for a UE in an MBMS mobile communication system are provided. A connected mode UE receives FLC applicability information for an interested MBMS service and keeps a current frequency or reselects to the PL of the MBMS service according to the FLC applicability information. Even if the FLC applicability information restricts FLC from the connected mode UE, the connected mode UE can reselect to the PL of the MBMS service according to its priority level.
