    Abstract: The present invention is related to a method of activating multiple bearer services in a long term evolution (LTE) wireless communication system including multiple bearers. At least one of the multiple bearers is activated during initial attach procedures which combine an attach procedure with activate packet data protocol (PDP) context activation procedures. In one embodiment, LTE attach procedures are implemented for multi-bearer services activation that establishes an LTE direct general packet radio service (GPRS) tunneling protocol (GTP) tunnel or normal GTP two-tunnels operation. In another embodiment, the initial attach procedures are used to activate a default PDP context to be followed by modified PDP context activation procedures for multi-bearer services activation. These procedures can be used to establish a modified LTE direct GTP tunnel or a normal GTP two-tunnels operation.

    Abstract: A method and apparatus for executing attachment procedures in a long term evolution (LTE) system to accommodate a single tunnel approach. Third Generation Partnership Program (3GPP) packet data protocol (PDP) context activation procedures are used for the allocation of an Internet protocol (IP) address and the establishment of tunneling between an evolved Node-B (eNodeB) and an anchor node, while allowing multiple radio access bearers (RABs) to be mapped to one PDP context for different quality of service (QoS) requirements. Thus, one PDP context is sufficient for a wireless transmit/receive unit (WTRU) within a single packet data network (PDN). Multiple PDP contexts can be established for special requirements, (e.g., bundled services), or when the WTRU connects to multiple PDNs.

    Abstract translation: 一种用于在长期演进（LTE）系统中执行附接过程以适应单个隧道方法的方法和装置。 第三代合作伙伴计划（3GPP）分组数据协议（PDP）上下文激活过程用于分配因特网协议（IP）地址以及在演进的节点B（eNodeB）和锚节点之间建立隧道，同时允许 要针对不同的服务质量（QoS）要求将多个无线电接入承载（RAB）映射到一个PDP上下文。 因此，一个PDP上下文对于单个分组数据网络（PDN）内的无线发射/接收单元（WTRU）是足够的。 可以针对特殊要求（例如，捆绑服务）或当WTRU连接到多个PDN时建立多个PDP上下文。

    Abstract: A wireless communication system and method of implementing an evolved system attachment procedure are disclosed. The system includes a first core network and a second core network which is evolved from the first core network. A wireless transmit/receive unit (WTRU) sends an attach request message to the second core network. The second core network activates a packet data protocol (PDP) context and sends an attach accept message to the WTRU. The attach accept message includes information regarding the PDP context. The second core network constructs a session and mobility management (SMM) context for session management (SM) and mobility management (MM) for the WTRU.

    Abstract: A single general packet radio service (GPRS) tunneling protocol (GTP) tunnel is established between an evolved Node B (ENB) and an access gateway (AGW) in a long term evolution (LTE) based wireless communication system. When ENB relocation is required, a new mobility management entity (MME)/user plane entity (UPE) sends a relocation request message to a target ENB indicating a tunnel endpoint identity (TEID) of the AGW, the identification number of a wireless transmit/receive unit (WTRU) and the packet data protocol (PDP) address of the WTRU. The new MME/UPE sends an update PDP context request message to the AGW indicating the target ENB TEID. The AGW updates a binding of the target ENB TEID with the WTRU PDP address and the identification number. A new tunnel is established between the target ENB and the AGW, and an old tunnel between the source ENB and the AGW is released. Both inter-location area (LA) and intra-LA handover scenarios are addressed.

    Abstract: In a wireless communications system including a third generation partnership project (3GPP) long term evolution (LTE) network, at least one alternative wireless network, and a wireless transmit/receive unit (WTRU), the 3GPP LTE network sends an indication of the availability of the alternative network or a list of available alternative networks in an area where the WTRU is located. The WTRU receives the information and initiates a handover procedure to the alternative wireless network based on the information. The WTRU may request a list of alternative wireless networks from the 3GPP LTE network, or may send capability information to the 3GPP LTE network. The alternative wireless network may be a 3GPP network, an interworking wireless local area network (I-WLAN), or a fixed broadband network.
