    • A method for estimating the location of a terminal operating in a communication system having at least two networks having overlapping areas of coverage, each network supporting at least one method for estimating the location of the terminal, and the terminal being in communication with a first one of the networks, the method comprising: assessing which of the networks is likely to form the more accurate estimate of the location of the terminal; and if that is the first one of the networks, estimating the location of the terminal by means of the first one of the networks, and if that is a second one of the networks, handing over the terminal to the second one of the networks and estimating the location of the terminal by means of the second one of the networks.
    • 一种用于估计在具有至少两个具有重叠覆盖区域的网络的通信系统中运行的终端的位置的方法,每个网络支持用于估计终端的位置的至少一种方法,并且终端与第一个通信 的方法包括:评估哪些网络可能形成对终端的位置的更准确的估计; 并且如果这是网络中的第一个,则通过第一个网络估计终端的位置,如果是网络中的第二个,则将该终端切换到第二个网络, 通过第二个网络来估计终端的位置。

    • The invention relates to a method for supporting a handover of a user equipment (15) from a first radio access network (11) to a second radio access network (13). In order to ensure the success of the handover, it is proposed that a core network stores at least for some user equipment (15) a list identifying all radio access networks, (11, 13) to which the respective user equipment (15) is allowed to be handed over. The core network can then transmit the information stored for a specific user equipment (15) to the first radio access network (11) (step c), so the first radio access network (11) can determine reliably before carrying out a handover by which other radio access network (13) a handover will be accepted. The invention equally relates to a core network, a network element of a core network and a network element of a radio access network that are designed for carrying out the proposed method.
    • 本发明涉及一种用于支持用户设备(15)从第一无线接入网(11)到第二无线接入网(13)的切换的方法。 为了确保切换的成功,提出核心网络至少存储一些用户设备(15)存储标识所有无线电接入网络(11,13)的列表,其中各个用户设备(15)是 允许被移交。 核心网络然后可以将存储的用于特定用户设备(15)的信息发送到第一无线电接入网络(11)(步骤c),使得第一无线电接入网络(11)可以在执行切换之前可靠地确定 其他无线电接入网(13)将接受切换。 本发明同样涉及核心网络,核心网络的网元和无线电接入网络的网元,用于实现所提出的方法。
