摘要： The present invention relates to a method for the redirection of a Multimedia Broadcast/Multicast Service (MBMS) session in a communication system comprising a plurality of node layers, wherein the MBMS session is redirected from one node to another node in the same node layer, such that the MBMS session is not aborted. The advantage of the invention is that an MBMS session can be redirected form one node to another node without aborting the MBMS session and thus there is no need to initialise a new MBMS session when a node in a communication system fails.
摘要翻译：本发明涉及一种用于在包括多个节点层的通信系统中重定向多媒体广播/多播服务（MBMS）会话的方法，其中MBMS会话被重定向到同一节点层中的另一个节点，使得MBMS会话不中止。本发明的优点是可以将MBMS会话从一个节点重定向到另一节点，而不会中止MBMS会话，因此当通信系统中的节点发生故障时，不需要初始化新的MBMS会话。

摘要： The present invention relates to a packet data support node (20 1 ) with a serving functionality and supporting over at least a first radio access network. It comprises mobility handling means and session handling means. It further comprises detecting means, in communication with said mobility handling means and with said session handling means, which are adapted to detect or establish initiation of a handover of a mobile station from the first or source radio access network. The session handling means are adapted to keep information about support for a direct tunneling functionality between the gateway packet data support node and the first radio access network. The detecting means are adapted to, upon detecting initiation of an HO from a first mode supporting direct tunneling (10) activate initiation of a reset of the direct tunnel and set up of two tunnel tunnels (10A, 10B) replacing said direct tunnel (10), each having a respective end point in the packet data support node.

摘要： The present invention relates to a method for context handling when a user equipment (10), UE, with established bearers towards a Gateway GPRS Support Node (11), GGSN, and a Packet Data Network GGSN (12), PGW- GGSN, moves from a previous Access Network, AN, to a present AN. The previous AN communicates with the GGSN (11) and the PGW-GGSN (12) via a previous Mobility Control Node (13), MCN. The present AN communicates with the PGW-GGSN (12) via a present MCN (14). The method comprises a step where the UE (10) detects (15) that it has entered a Mobility Area, MA, belonging to the present AN and requests for a Mobility Area Update, MAU, at the present MCN (14). The method is particularly characterized in the steps of: - The present MCN (14) derives (16) the previous MCN (13) from the MAU request and initiates a handshake procedure including exchange of capabilities with the previous MCN (13). - The present MCN (14) sends a context acknowledge message to the previous MCN (13) when it has accepted the MAU request and updated the established bearers towards the PGW-GGSN (12). - The previous MCN (13) removes at least one Packet Data Protocol, PDP, context existing in the GGSN (11) as a result of the context acknowledge message.
摘要翻译：本发明涉及一种用于在向网关GPRS支持节点（11），GGSN和分组数据网络GGSN（12），PGW-GGSN建立承载的用户设备（10），UE移动时，上下文处理的方法从先前的接入网络AN到现在的AN。先前的AN通过先前的移动性控制节点（13）MCN与GGSN（11）和PGW-GGSN（12）进行通信。本AN通过目前的MCN（14）与PGW-GGSN（12）进行通信。该方法包括以下步骤：UE（10）检测（15）已经进入属于本AN的移动区域MA，并且在当前MCN（14）下请求移动区域更新MAU。该方法的特征在于以下步骤： - 本MCN（14）从MAU请求中导出（16）先前的MCN（13），并发起包括与先前MCN（13）的能力交换的握手过程。 - 当MCN（14）已经接受MAU请求并将建立的承载更新到PGW-GGSN（12）时，当前MCN（14）向上一个MCN（13）发送上下文确认消息。 - 前一个MCN（13）作为上下文确认消息的结果，去除了GGSN（11）中存在的至少一个分组数据协议（PDP）上下文。

摘要： The present solution relates to a method in a source serving gateway (207a) for triggering relocation of at least one user equipment bearer resource from the source serving gateway (207a) to at least one target serving gateway (207b) in a communication network (200). The source serving gateway (207a) serves the user equipment (203) by providing bearer resources to the user equipment (203). The source serving gateway (207a) detects (501) an event indicating relocation of the at least one user equipment bearer resource from the source serving gateway (207a) to the at least one target serving gateway (207b). Furthermore, the source serving gateway (207a) sends (502) a message to a mobility management node (205, 209). The message comprises a trigger to relocate the at least one user equipment bearer resource from the source serving gateway (207a) to the at least one target serving gateway (207b).

摘要： The present invention relates to a mobility management entity for a GPRS Core Network. The mobility management entity is arranged to handle at least control data between a user plane entity and a Radio Access Network Node for subscribers associated to said Radio Access Network Node. The mobility management entity is arranged to receive a move message, indicating that it shall take over said handling of at least control data for one or more of said subscribers from another mobility man- agement entity. It is arranged to upon reception of said move message send a relocation request message to the Radio Access Network Node so as to switch transmission of control data for transfer between the Radio Access Network Node and itself instead of a currently allocated mobility management entity, and send an update re- quest message to the user plane entity so as to switch transmission of control data for transmission between the user plane entity and itself.

摘要： Systems and methods are disclosed herein for Access and Mobility Function (AMF) re-allocation. In one embodiment, a method for AMF re-allocation comprises, at an initial AMF, receiving a registration request for a User Equipment (UE) from a Radio Access Network (RAN), deciding to initiate an AMF re-allocation procedure, sending the registration request to the RAN for delivery to a target AMF for the AMF re-allocation procedure, and sending a UE security context of the UE to another Network Function (NF). The method further comprises, at the target AMF, receiving a message from the RAN wherein the message comprises the registration request from the UE, obtaining the UE security context of the UE from the other NF, and performing protected NAS signaling related to a registration procedure for the UE using the UE security context of the UE.
