Abstract: The present disclosure discloses a method for supporting release of a SIPTO bearer or a LIPA bearer in dual-connectivity architecture. The method is implemented as follows. A MeNB sends a message to a SeNB. The message contains indication information for SIPTO at local network bearer deactivation or LIPA bearer deactivation. The indication information may indicate the SeNB to notify a collocated LGW of releasing PDN connection of SIPTO at local network or the PDN connection of LIPA. After receiving the message, the SeNB removes radio and control plane related resources associated to the UE context or the SIPTO at local network bearer or the LIPA bearer, and if the message contains the indication information for SIPTO@LN bearer deactivation or LIPA bearer deactivation, sends an internal signaling to the collocated LGW to indicate the collocated LGW to release the PDN connection of the SIPTO at local network or the PDN connection of the LIPA. The SeNB is a SeNB supporting functions of the LGW that supports operations of the SIPTO at local network or the operations of the LIPA. By the method of the present disclosure, the SIPTO bearer or the LIPA bearer in the dual-connectivity architecture can be released, thereby avoiding inaccurate operations in an access network, ensuring that the SIPTO bearer or the LIPA bearer can be released duly and accurately, and avoiding inaccurate release of the SIPTO bearer or the LIPA bearer.

Abstract: The present disclosure provides a method for supporting UE access control. A base station is informed by a ProSe Function via a MME or informed by the MIME of information indicating whether a UE is authorized for a D2D service. The base station performs an access control to the UE according to the information indicating whether the UE is authorized for the D2D service. The present disclosure further provides a method in which a source base station informs a target base station of the information indicating whether the UE is authorized for a D2D service. The target base station performs an access control according to the information.

Abstract: A method for handover of User Entity (UE) by a source Base Station (BS) is provided. The method includes determining whether to handover the UE using an X2 interface, transmitting a handover request message to a target BS, the handover request message including Closed Subscriber Group (CSG) information of the target BS, and receiving a handover request acknowledgement message from the target BS, wherein the determining of whether to handover the UE using the X2 interface includes, if there is the X2 interface between the source BS and the target BS, and if the target BS does not support a CSG or the target BS supports a same CSG supported by the source BS, determining to perform the handover of the UE using the X2 interface, and obtaining the CSG information of the target BS through an X2 interface set up procedure.

Abstract: The present disclosure discloses methods, systems and devices for supporting local breakout in a small cell architecture. A MME sends information of a local breakout bearer for a UE to a MeNB, and the MeNB determines a local home network to which the local breakout bearer belongs according to the received information. When the MeNB is to switch the local breakout bearer between different eNBs, the MeNB selects an eNB in the local home network to which the local breakout bearer belongs as a target eNB. By the present disclosure, the continuity of local breakout traffic may be ensured when a User Equipment (UE) moves in a small cell scenario, thereby avoiding data loss and improving user experiences. Further, a local breakout bearer may be released timely and reasonably, thereby saving system resources.

Abstract: A method of Minimization of Drive Tests (MDT) continuous measurement under multiple Public Land Mobile Networks (PLMNs) is provided. The method includes sending, by an eNB, MDT-related information to a target eNB, or, requesting, by the target eNB, for user consent information from an MME, and transmitting the user consent information among multiple PLMNs without being lost during transmission. In addition, a method for achieving MDT reporting is provided. The method includes reporting, by the UE, a new indication, or, reporting, by the UE, a PLMN identifier configuring the MDT to the eNB, and enabling the eNB to correctly determine whether the UE is requested to report the measurement record to the eNB.

Abstract translation: 提供了一种在多个公共陆地移动网络（PLMN）下最小化驱动测试（MDT）连续测量的方法。 该方法包括由eNB向目标eNB发送MDT相关信息，或者由目标eNB向MME发送用户同意信息，并在多个PLMN之间发送用户同意信息，而不会在传输期间丢失。 另外，提供了实现MDT报告的方法。 该方法包括由UE向eNB报告新的指示，或者由UE向eNB报告配置MDT的PLMN标识符，并且使得eNB能够正确地确定UE是否被请求将测量记录报告给 eNB。
