    摘要： The present invention relates to a method and apparatus for updating a key for encrypting multicast data in a wireless communication system. The method of the present invention is characterized by comprising: an information receiving step of receiving information on a group entry time and a group exit time from users who have newly entered an arbitrary group including at least one subgroup; a grouping step of grouping the users using the information on the group entry time and the group exit time; and a key transmission step of either transmitting, to the newly-entered users, keys related to the group and the subgroups, or updating, for the remaining users of the subgroups, both the key related to the subgroup to which the user exiting the group belongs and the key of the group and then transmitting the updated keys to the users of the subgroups.

    摘要： A method and apparatus for supporting Non-Access Stratum (NAS) communication between a User Equipment (UE) and a Mobility Management Entity (MME) efficiently by addressing signaling problems occurring between the UE and the MME in a situation where it is necessary for a network node to identify the UE information, from another network node to which the UE has been attached, are provided. The method is implemented with a UE, an MME, and an old MME or an old Serving General Packet Radio Service Support Node (SGSN) to which the UE has been attached before so as to facilitate discovering a best node using the UE information acquired from the old MME or old SGSN during communication between the UE and the network, resulting in a reduction of a communication delay between the UE and network and an improvement of communication efficiency.
