    • A method and apparatus for implementing a handoff between radio access networks (RANs) deployed under different radio access technologies (RATs) are disclosed. A wireless transmit/receive unit (WTRU) is equipped with at least two radio units to support the RATs. Each RAN sends a list of co-located RANs in the coverage area of the RAN to the WTRU. The WTRU stores the list and determines whether handoff criteria is met by one of the co-located RANs. The WTRU then initiates a handoff from a current RAN to a target RAN if the handoff criteria is met by the target RAN. Alternatively, the WTRU may send a measurement report to the current RAN, whereby the current RAN determines whether handoff criteria is met by a selected one of the co-located RANs and initiate a handoff to the selected RAN if the handoff criteria is met. ® KIPO & WIPO 2008
    • 公开了一种用于实现在不同无线电接入技术(RAT)下部署的无线电接入网络(RAN)之间切换的方法和装置。 无线发射/接收单元(WTRU)配备有至少两个无线电单元以支持RAT。 每个RAN在RAN的覆盖区域中向WTRU发送共同定位的RAN的列表。 WTRU存储列表并且确定切换标准是否由共同定位的RAN之一满足。 如果目标RAN满足切换标准,则WTRU然后发起从当前RAN到目标RAN的切换。 或者,WTRU可以向当前RAN发送测量报告,由此当前RAN确定所选择的一个同位置RAN是否满足切换标准,并且如果满足切换标准,则发起切换到所选择的RAN。 ®KIPO&WIPO 2008

    • A wireless communication system processing evolved system attachment and a method thereof are provided to adopt an IP address for the whole operation of a WTRU in SM(Session Management) and MM(Mobility Management) and enable the IP address to be allocated if the WTRU is connected to an evolved CN, and enable the WTRU to be in a detached/attached state if any IP address is not allocated, so that the state transition between MM states is changed according to allocation of the IP address. A system attachment method comprises the following steps of: enabling a WTRU(Wireless Transmit/Receive Unit)(1002) to transmit an attachment request message to the second CN(Core Network)(1006)(1022); enabling the second CN(1006) to activate a PDP(Packet Data Protocol) context including an IP(Internet Protocol) address; and enabling the second CN(1006) to transmit an attachment acceptance message including the IP address to the WTRU(1002). The attachment request message includes IMSI(International Mobile Subscriber Identity).
    • 提供了一种无线通信系统处理演进系统附件及其方法,以在SM(会话管理)和MM(移动性管理)中采用用于WTRU的整个操作的IP地址,并且如果WTRU是 连接到演进的CN,并且如果未分配任何IP地址,则使WTRU能够处于分离/附着状态,使得根据IP地址的分配来改变MM状态之间的状态转换。 系统附接方法包括以下步骤:使得WTRU(无线发射/接收单元)1002能够向第二CN(核心网络)(1002)发送附件请求消息(1022); 使第二CN(1006)激活包括IP(因特网协议)地址的PDP(分组数据协议)上下文; 以及使所述第二CN(1006)能够向所述WTRU(1002)发送包括所述IP地址的附件接受消息。 附件请求消息包括IMSI(国际移动订户身份)。
