摘要:
This invention relates to wireless local area networks (WLANs), and the interoperability of networks of different types or conforming to different standards, and to methods and apparatus to allow a multimode wireless transmit/receive unit (WTRU), which is able to operate in more than one type of network, to handover from one network type to another without adversely affecting service, utilizing a mechanism and information flows implemented in a new protocol stack.
摘要:
A wireless communication system including at least one IEEE 802 multi-stack wireless transmit/receive unit (WTRU) and a plurality of technologically diversified access networks, such as IEEE 802.X networks and Third Generation Partnership Project (3GPP) networks, that are concurrently deployed. Both the multi-stack WTRU and the technologically-diversified networks include a media independent handover (MIH) function. The WTRU is configured to read MIH information transmitted from one of the IEEE 802.X networks, trigger 3GPP authentication and authorization procedures based on the MIH information, obtain a local Internet protocol (IP) address, establish a tunnel to a packet data gateway (PDG) in a 3GPP core network, construct a care of address (CoA) and register the CoA with a home agent of the WTRU, whereby data destined for the WTRU is routed via the home agent through a new tunnel established between the home agent and a foreign agent based on the CoA.

摘要:
In a wireless communication system, a wireless transmit receive unit (WTRU) adapted to bundle a plurality of services into radio access bearer (RAB) in an uplink signal and unbundle a plurality of services from a RAB in a downlink signal. The WTRU is adapted to communicate with a plurality of services through a communications tunnel.
摘要:
A wireless communication method and system for performing dual mode paging over a wireless communication network having both a second-generation/third-generation (2G/3G) radio access network (RAN) and an evolved-universal mobile telecommunication system (UMTS) terrestrial radio access network (E-UTRAN). When a wireless transmit/receive unit (WTRU) registers or originates traffic with an evolved network, no additional signaling is required Otherwise, the WTRU is paged via both of the 2G/3G RAN and the E-UTRAN, depending on the response from the WTRU, data is forwarded to the WTRU via the 2G/3G RAN or the E-UTRAN.
摘要:
A method and system for reporting short message (SM) capability over an IP multimedia subsystem (IMS) using a session initiation protocol (SIP) are disclosed. A wireless transmit/receive unit (WTRU) registers with a core network and sends a message indicating its SM capability via the IMS to the core network. The core network then updates the WTRU capabilities based on the message and routes an SM to the WTRU via the IMS.
摘要:
A method for delivering a short message service (SMS) message to an interworking wireless local area network user equipment (UE) begins by registering the UE with an Internet Protocol short message gateway (IP-SM-GW). A capability report is sent from the UE to the IP-SM-GW, the capability report including the capabilities of the UE. A SMS message is transmitted from a short message service center (SMSC) to the IP-SM-GW. The capabilities of the UE are evaluated at the IP-SM-GW to determine whether the UE can receive the SMS message, and the SMS message is delivered to the UE via the IP-SM-GW if the UE has the capabilities to receive the SMS message.
摘要:
The present invention is related to a method and system for providing a wireless transmit/receive unit (WTRU) status, in providing real time services via a wireless local area network interworking with 3GPP systems. An entity such as a packet data gateway (PDG) in the 3GPP network stores and maintains the current state of the WTRU and updates the state of the WTRU when it changes. The WTRU signals a change in its state to the PDG. When the PDG receives a message from the 3GPP system directed to the WTRU, the PDG examines the status of the WTRU prior to forwarding the message to the WTRU.
