Method and apparatus for allowing user equipment to determine validity of system information before receiving the same in a network sharing system

摘要

A method and apparatus are provided for receiving system information during inter-cell movement of a user equipment (UE) in a network sharing (NS) system. The UE moves from a previous cell to a new cell. After the movement, the UE compares a public land mobile network (PLMN) identity indicating a PLMN to which the previous cell belongs, with a PLMN identity indicating a PLMN to which the new cell belongs. If the PLMN identity of the new cell is equal to the PLMN identity of the previous cell, the UE sets system information blocks that it has received and stored in the previous cell, as system information of the new cell. If the PLMN identity of the new cell is not equal to the PLMN identity of the previous cell, the UE receives system information blocks with ‘Area scopes Cell and PLMN’ from the new cell, considering that the system information for the previous cell will be invalid in the new cell.

1. A method for receiving system information during inter-cell movement of a user equipment (UE) in a network sharing (NS) system, the method comprising the steps of:
moving, by a UE, from a previous cell to a new cell; comparing a first public land mobile network (PLMN) identity indicating a first PLMN to which the previous cell belongs, with a second PLMN identity indicating a second PLMN to which the new cell belongs; setting first system information blocks received and stored by the UE in the previous cell as second system information of the new cell if the second PLMN identity is equal to the first PLMN identity; and receiving second system information blocks from the new cell if the second PLMN identity is not equal to the first PLMN identity, wherein first system information of the previous cell is considered to be invalid in the new cell.
