    Abstract: A method for a proxy mobile internet protocol (PMIP) supporting a mobile access gateway (MAG) is described. The method includes receiving a first packet with a first internet protocol (IP) address from a local mobility anchor (LMA). The LMA is a hybrid mobility anchor used for both multicast and unicast traffic. The method also includes receiving a second packet with a second IP address from the LMA, receiving a third packet from the LMA, and communicating multicast information to the LMA via an aggregated multicast tunnel.

    Abstract: A method for supporting proxy mobile internet protocol (PMIP) in a local mobility anchor (LMA) is described. The method includes receiving a request for multicast information corresponding to a request for multicast services from at least one of a plurality of wireless transmit/receive units (WTRUs) which require multicast services associated with a multicast group. The method also includes transmitting, to a mobile access gateway (MAG) via an aggregated multicast tunnel, multicast information for distribution to at least one of the plurality of WTRUs in the multicast group. The multicast information comprises an IP address corresponding to the multicast group.

    Abstract: Wireless transmit and receive units (WTRUs) and methods for pre-association discovery (PAD) are disclosed. The methods may include obtaining an IP address to communicate with a wireless local area network (WLAN) before associating with the WLAN for the purpose of performing PAD. The methods may include communicating with a remote information server (IS) by sending messages to the WLAN using an L2 address and receiving responses from the IS through the WLAN. The methods may include receiving a message including a source IP address from an unassociated WTRU and restricting the use of the source IP address by the unassociated WTRU. The methods may include receiving a PAD request from a WTRU and relaying messages between the WTRU and a remote IS for PAD information exchange. The WTRU may not have an IP address for use with the WLAN and the WTRU may not be associated with the WLAN.

    Abstract translation: 公开了用于预关联发现（PAD）的无线发射和接收单元（WTRU）和方法。 所述方法可以包括在与WLAN之间关联以执行PAD的目的之前获得与无线局域网（WLAN）通信的IP地址。 所述方法可以包括通过使用L2地址向WLAN发送消息并通过WLAN接收来自IS的响应来与远程信息服务器（IS）进行通信。 所述方法可以包括从未关联的WTRU接收包括源IP地址的消息，并且限制未关联的WTRU使用源IP地址。 所述方法可以包括从WTRU接收PAD请求，并且在WTRU和用于PAD信息交换的远程IS之间中继消息。 WTRU可以不具有用于WLAN的IP地址，并且WTRU可以不与WLAN相关联。
