Abstract: Disclosed is a method and device for binding a user and a UE in a mobile communication system. A method by a network entity may comprise receiving provisioning information for a user from a service provider, receiving a binding request message including verification information and a digital user identifier from a user equipment completing user authentication for the service provider, verifying the verification information using the provisioning information, and the verification information being successfully verified, binding the digital user identifier with the UE's subscriber information and storing in a subscriber database. The subscriber database may be used to provide a service corresponding to a service invocation to the UE in response to receiving the service invocation including the digital user identifier from the service provider.

Abstract: The present invention relates to a method and apparatus for group communication. In more detail, the present invention relates to a method and apparatus for allowing a terminal to participate in group communication effectively on the move, and a communication method of a base station in a mobile communication system according to the present invention includes receiving Multimedia Broadcast Multicast Service (MBMS) bearer information including a QoS parameter from a Multi-cell/multicast Coordination Entity (MCE); updating bearer information for a terminal using the received MBMS bearer information; making a handover decision of the terminal and transmitting a handover request message including the MBMS bearer information to a Mobility Management Entity (MME) or a second base station which does not support MBMS; transmitting a handover command message from the second base station to the terminal; and forwarding MBMS data to the second base station during a predetermined period. The group communication service reception method and apparatus of the present invention is advantageous in that a terminal participated in group communication is capable of receiving the group communication service seamlessly, even when the terminal enters an area not supporting MBMS, by switching the communication path to a Point-To-Point (PTP) communication path quickly.

Abstract: Methods and apparatuses are provided for releasing an internet protocol (IP) address by a packet data network gateway (PGW) in a mobile communication system. The PGW allocates an IP version 4 (IPv4) address and an IP version 6 (IPv6) address to a terminal to establish a packet data network (PDN) connection between the terminal and the PGW. The PGW identifies a PDN type associated with the PDN connection if an event of releasing the IPv4 address has occurred. The PGW transmits, to a serving gateway (SGW), a binding revocation message, including information indicating release of the IPv4 address, with the PDN connection remaining, if the PDN type is IPv4 and IPv6. The PGW receives a binding revocation acknowledge message in response to the binding revocation request message, from the SGW.

Abstract translation: 提供了用于在移动通信系统中通过分组数据网络网关（PGW）释放因特网协议（IP）地址的方法和装置。 PGW向终端分配IP版本4（IPv4）地址和IP版本6（IPv6）地址，以在终端和PGW之间建立分组数据网络（PDN）连接。 如果发生IPv4地址释放的事件，则PGW识别与PDN连接相关联的PDN类型。 如果PDN类型是IPv4和IPv6，则PGW向服务网关（SGW）发送包括指示IPv4地址释放的信息，剩余PDN连接的绑定撤销消息。 PGW从SGW接收响应于绑定撤销请求消息的绑定撤销确认消息。
