A management method and apparatus for a Closed Subscriber Group (CSG) white list are provided in the present invention, which can avoid the case that causes the CSG white list of a User Equipment (UE) to include a new Operator CSG List (OCL) and an old Allowed CSG List (ACL). The method includes the following steps: a User Equipment (UE) receives an updated Operator CSG List (OCL) or an Allowed CSG List (ACL) from a network side; according to the updated OCL or ACL, UE generates the CSG white list. With the present invention, when UE performs cells selection or handover according to the CSG white list which is provided to a non-access stratum by an access stratum as a basis for access control, the selected CSG identifier can not be refused by the network, the user experience can not be reduced, and unnecessary network signaling overhead can not be increased.

A method for determining a single frequency network area, applied to a broadcasting and multicasting technology field, includes: determining a cell or a cell cluster with a terminal subscribing to the broadcast multicast service; determining a cell or a cell cluster without a terminal subscribing to the broadcast and multicast service that is neighboring to the cell or the cell cluster with a terminal subscribing to the broadcast multicast service, as an auxiliary cell or an auxiliary cell cluster; selecting the auxiliary cell or the auxiliary cell cluster that satisfies the predetermined conditions, and determining both the selected auxiliary cell or the auxiliary cell cluster and the cell or the cell cluster with a terminal subscribing to the broadcast and multicast service as a single frequency network area. Also, a device for determining the single frequency network area is provided.

A method and device for indicating data re-transmission when area switching in LTE system, wherein the method comprises the following steps: S_eNB sends PDCP-SDU CN report to T_eNB in order to announce PDCP-SDU SN received, and T_eNB announces PDCP-SDU SN received by S_eNB to UE. Thereby, UE would not re-transmit PDCP-SDU corresponding to received SN, which avoids re-transmission of useless PDCP-SDU, and saves radio resources comparing with prior solutions.

Embodiments of the present invention provide a method, system and relevant apparatuses for supporting addressing by a user static Internet Protocol (IP) address in a Long Term Evolution (LTE) system. The method includes: when a user attaches to a network, downloading, by a Home Subscriber Server (HSS), user subscription data including a user static IP address and information of a corresponding Access Point Name (APN) to a Mobility Management Entity (MME); sending, by the MME, the user static IP address and the information of the corresponding APN to a Serving Gateway (S-GW) through a Create Default Bearer Request message; sending, by the S-GW, the user static IP address, the information of the corresponding APN and an address of an S-GW serving the user to a Packet Data Network Gateway (P-GW) corresponding to the APN which corresponds to the user static IP address; and establishing, by the P-GW, a default bearer according to the user static IP address, the information of the corresponding APN and the address of the S-GW serving the user. The present invention solves the packet data addressing problem of the user static IP address in a simple manner. The procedure is simple and convenient for use and has better applicability.
