Abstract: A method and an apparatus for a proxy mobile Internet protocol (PMIP) supporting a dedicated multicast local mobility anchor (LMA) and mobile access gateway (MAG) is provided. The LMA assigns an Internet Protocol (IP) address to a wireless transmit receive unit (WTRU) that processes the IP address and sends a router solicitation message to a serving MAG. A WTRU is disclosed to receive a first IP address that is for unicast service and a second IP address that is for multicast services. Generally, the method and apparatus proposes architecture, interfaces, and procedures to enable multicast mobility using Proxy Mobile IP. More specifically operations of aggregated PMIP tunnels for multicast services are described. Multicast mobility is enabled when mobile nodes move from one MAG to another MAG, intra-LMA, and inter-LMA. And, Multicast mobility is enabled between bidirectional network and downlink only multicast network in a hybrid network.

Abstract: A Media Independent Handover (MIH) server communicates with nodes in a cellular network to perform handover of a wireless transmit/receive unit (WTRU) in the event of an incoming circuit-switched (CS) call. A Gateway Mobile Switching Center (GMSC) and/or Home Location Register (HLR) receive an indication of an incoming call, and may communicate with the MIH server. A determination is made regarding whether the WTRU is active in the cellular network. When required, the MIH server initiates an MIH handover of the WTRU to the cellular network. The WTRU hands over to the cellular network and receives the call. Additionally, an MIH server and a HLR communicate location information associated with a WTRU. The location information may be used by the MIH server and HLR to perform their respective MIH and HLR functionality, and/or to handover the WTRU to a cellular network in the event of an incoming CS call.

Abstract: The invention is a novel slot structure and method of transmitting data at a controllable power level. The slot comprises a header, a DATA field adjacent the header and a ramp interval adjacent the DATA field. The method consists of transmitting the entire slot at a sufficiently high power when the DATA field is occupied by data traffic or control information but to lower the power during transmission of the DATA field when the slot is a null slot. In the latter case, a gradual decrease of the transmitted power is effected during the first few symbols of the DATA field, whereas the power is brought back to a higher level during the ramp interval. The new power level may be higher or lower than the initial power level, depending on the destination mobile unit associated with the following slot.

Abstract translation: 本发明是一种以可控功率电平发送数据的新颖的时隙结构和方法。 该时隙包括报头，与报头相邻的DATA字段以及与DATA字段相邻的斜坡间隔。 该方法包括当DATA字段被数据业务或控制信息占用时以足够高的功率发送整个时隙，但是当该时隙是空时隙时，在DATA字段的传输期间降低功率。 在后一种情况下，在DATA字段的前几个符号期间实现发射功率的逐渐降低，而在斜坡间隔期间功率被恢复到较高的电平。 新功率电平可以高于或低于初始功率电平，这取决于与下一个插槽相关联的目标移动单元。

Abstract: A wireless transmit/receive unit (WTRU) includes a mobility management function and a multihoming function. The mobility management function may implement the Media Independent Handover (MIH) protocol and the multihoming function may implement the Shim6 protocol. The mobility management function may communicate link status information to the multihoming function. Based on the link status information, the multihoming function may accelerate or decelerate a link failure detection procedure, may modify a list of possible paths for consideration for a path exploration procedure, and/or may determine to initiate a path exploration procedure. The multihoming function may communicate to the mobility management function that additional communications resources are required. In response, the mobility management function may activate an inactive radio interface. Subsequent path exploration procedures may include the exploration of paths that may be established over the activated radio interface.
