    • A network architecture comprising at least one core network, each core network comprising a number of packet data gateway access supporting nodes GASNs handling mobile user station access over an access network, said core network(s) further providing access to one or more global packet data communication networks (IN), and one or more nodes holding subscriber or mobile user station related information. The GASNs are further adapted to support intercommunication over a mobility protocol interface to, at reception of a request for change of access type from a mobile user station, establish information about the previous GASN of the mobile user station, and to, using the established information, update an established communication context concerning the mobile user station or create a new communication context concerning the mobile user station such that mobility between different access network types is enabled for a mobile user station without interruption of an ongoing session.
    • 包括至少一个核心网络的网络架构,每个核心网络包括多个分组数据网关接入支持节点GASN:通过接入网络处理移动用户站接入,所述核心网络进一步提供对一个或多个全局分组数据通信的接入 网络(IN)和一个或多个保存订户或移动用户站相关信息的节点。 GASN还适用于支持移动性协议接口的相互通信,在接收到来自移动用户站的接入类型改变的请求时,建立关于移动用户站的先前GASN的信息,并且使用 建立信息,更新关于移动用户站的建立的通信上下文,或者创建关于移动用户站的新的通信上下文,使得在不中断正在进行的会话的情况下,为移动用户站启用不同接入网络类型之间的移动性。

    • There is provided methods for a user equipment (UE) and a user equipment being adapted to be attached and connected to a 2G/3G access network via a mobile switching centre (MSC) for performing at least circuit switched, CS, communication, or via a LTE access network and further on to a mobility management entity (MME) node, for performing packet switched, PS, and/or circuit switched, CS, communication. The user equipment (UE) is being adapted to receiving page signals (11, 12, 13) from the network side so as to inform the user equipment of incoming calls, the user equipment moreover being adapted to respond to page signals, such as by issuing page response signals (20). The user equipment (UE) is being adapted for responding with an Extended Service Request (15) message to the mobility management entity (MME) for triggering the mobility management entity (MME) to initiate handover to the 2G/3G access network. The user equipment—when receiving a page request (13; 61) stemming from a mobile switching centre (MSC), such as an IMSI page message (13) via a MME (12), and the IMSI page message contains a IMSI (62) and a CS domain indicator,—the user equipment being adapted for, without attempting to re-attach (63) to the mobility management entity (MME) over which the page was received, issuing a page response message (20; 68) to the mobile switching centre (MSC), thus performing cell reselection (67) to a 2G/3G access network for performing CS communication via the mobile switching centre (MSC).
    • 提供了一种用于用户设备(UE)和用户设备适于通过移动交换中心(MSC)附接并连接到2G / 3G接入网络的方法,用于至少执行电路交换,CS,通信或经由 LTE接入网络,并且还进一步用于执行分组交换,PS和/或电路交换,CS,通信的移动性管理实体(MME)节点。 用户设备(UE)适于从网络侧接收寻呼信号(11,12,13),以便向用户设备通知呼入呼叫,用户设备还适于响应寻呼信号,例如通过 发出页响应信号(20)。 用户设备(UE)被适配为向移动性管理实体(MME)发送用于响应的扩展业务请求(15)消息,用于触发移动性管理实体(MME)发起到2G / 3G接入网的切换。 用户设备 - 当从移动交换中心(MSC)(例如IMSI寻呼消息(13))经由MME(12)接收到寻呼请求(13; 61)和所述IMSI寻呼消息包含IMSI(62 )和CS域指示符,所述用户设备适于,而不尝试重新附加(63)到所述页面被接收到的移动性管理实体(MME),向所述移动性管理实体(MME)发送寻呼响应消息(20; 68) 移动交换中心(MSC),从而对2G / 3G接入网执行小区重选(67)以便经由移动交换中心(MSC)进行CS通信。
