    • The present invention defines an efficient method for (re)selecting a cell according to a speed of a terminal in a HetNet where cells having various regions such as macro cells, pico cells and femto cells are arranged in the same frequency band in a mobile communication system. A cell selection control method of a terminal in a mobile communication system, according to an embodiment of the present invention, comprises a step of receiving, from a base station, cell list information for not allowing a terminal moving at a high speed to select a cell and a step of setting the terminal so that cells included in the cell list information are considered or not considered to be targets of selection or reselection when the terminal moves at the high speed. According to the present invention, in a network consisting of various types of cells using the same frequency band, the terminal can determine whether to select or reselect a cell according to the speed of the terminal. That is, the terminal moving at the high speed does not select or reselect a frequent service cell, thereby efficiently performing the cell selection or reselection. Further, power consumption of the terminal can be reduced.
    • 本发明定义了一种根据HetNet中的终端的速度(重新)选择小区的有效方法,其中具有诸如宏小区,微微小区和毫微微小区等各种区域的小区在移动通信中被布置在相同的频带中 系统。 根据本发明的实施例的移动通信系统中的终端的小区选择控制方法包括从基站接收不允许终端高速移动的小区列表信息选择一个 小区和设置终端的步骤,使得当终端以高速移动时,包括在小区列表信息中的小区被认为是不被认为是选择或重选的目标。 根据本发明,在由使用相同频带的各种类型的小区组成的网络中,终端可以根据终端的速度来确定是选择还是重新选择小区。 也就是说,以高速移动的终端不选择或重新选择频繁的服务小区,从而有效地执行小区选择或重选。 此外,可以减少终端的功耗。

    • A dual mode mobile terminal (30) is capable of communicating (e.g., with a core network) either via a first radio access network (12) having a first type radio access technology (GSM) or a second radio access network (14) having a second type radio access technology (UTRAN). When conditions warrant, a network node prepares a radio access technology (RAT) handover message for transmission to the equipment unit (UE) in conjunction with handover of the mobile terminal (MT) from the first radio access network to the second radio access network, and an associated change of operation mode of the mobile terminal (MT) from the first mode to the second mode. In accordance with the present invention, a radio access technology handover message includes a first information element representative of a first parameter from which a value of a second parameter can be derived so that the second parameter need not be included as a separate information element in the radio access technology handover message. Not including the second parameter as a separate element in the radio access technology handover message facilitates non-segmentation of the radio access technology handover message. In one aspect of the invention, the radio access technology handover message is a RRC Handover to UTRAN message; the first parameter is a Serving-Radio Network Temporary Identifier (S-RNTI 2); and, the second parameter is an information element which facilitates distribution of load and transmission of traffic in the radio access network (e.g., a Default DPCH Offset Value).
    • 双模式移动终端(30)能够经由具有第一类型无线电接入技术(GSM)的第一无线电接入网络(12)与第二无线电接入网(14)进行通信(例如,与核心网络) 第二类无线电接入技术(UTRAN)。 当条件允许时,网络节点与移动终端(MT)从第一无线电接入网络到第二无线电接入网络的切换一起准备用于传输到设备单元(UE)的无线电接入技术(RAT)切换消息, 以及从第一模式到第二模式的移动终端(MT)的操作模式的相关联的改变。 根据本发明,无线电接入技术切换消息包括表示第一参数的第一信息元素,从该第一参数可以导出第二参数的值,使得第二参数不需要作为单独的信息元素包括在 无线电接入技术切换消息。 在无线电接入技术切换消息中不包括作为单独元素的第二参数有利于无线电接入技术切换消息的非分段。 在本发明的一个方面,无线接入技术切换消息是RRC切换到UTRAN消息; 第一个参数是服务无线网络临时标识符(S-RNTI 2); 并且第二参数是便于分发无线电接入网络中的业务的负载和传输的信息元素(例如,默认DPCH偏移值)。
