Abstract: A METHOD AND APPARATUS FOR IMPLEMENTING A HANDOFF BETWEEN RADIO ACCESSNETWORKS (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 (110A, 110B) IN THE COVERAGE AREA OF THE RAN TO THE WTRU. THE WTRU (150) 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 (110A, 110B) AND INITIATE A HANDOFF TO THE SELECTED RAN IF THE HANDOFF CRITERIA IS MET.

Abstract: A METHOD AND SYSTEM FOR REPORTING EVOLVED UNIVERSAL MOBILE TELECOMMUNICATION SYSTEMS (UTMS) TERRESTRIAL RADIO ACCESS NETWORK (E-UTRAN) (218) CAPABILITIES ARE DISCLOSED. A WIRELESS TRANSMIT/RECEIVE UNIT (WTRU) (302) SENDS A FIRST MESSAGE TO A CORE NETWORK (CN) (116) TO REPORT THE E-UTRAN CAPABILITIES OF THE WTRU. THE CN THEN UPDATES THE WTRU CAPABILITIES BASED ON THE FIRST MESSAGE. THE FIRST MESSAGE MAY INCLUDE A RADIO ACCESS CAPABILITY INFORMATION ELEMENT (IE) WHICH CARRIES INFORMATION RELATED TO E-UTRAN CAPABILITIES OF THE WTRU AND/OR A NETWORK CAPABILITY IE WHICH CARRIES INFORMATION REGARDING NETWORK CAPABILITIES OF THE WTRU. THE CN (116) MAY SEND A SECOND MESSAGE TO THE WTRU (302) TO REPORT NETWORK CAPABILITIES WITH RESPECT TO THE RADIO ACCESS NETWORKS (RANS) TO WHICH THE CORE NETWORK IS CONNECTED AND SERVICES THAT CAN BE PROVIDED OVER THE E-UTRAN (218).

Abstract: A method and apparatus for handover of a dual mode wireless transmit/receive unit (WTRU) from an LTE system to a GERAN system uses measurements of the LTE and GERAN frequencies and a decision by a source evolved Node B to perform the handover. A GERAN access procedure includes PS attach messages exchanged between the WTRU and the target base station controller and a target SGSN. Alternatively, the GERAN access procedure uses RAN mobility information messages exchanged by the WTRU and the target base station controller and a relocation detect message by the source evolved Node B.

Abstract: Method and apparatus delivering voice/data services within a piconet operating over a limited range or over a WLAN communicating with 3GPP devices by reformatting data into IP format before delivering to the WLAN. The service is short message service (SMS). Upon receipt of an SMS message, relevant routing information is retrieved. A PDGW address for the SMS message is identified and is sent to the PDGW address which identifies the WLAN user equipment (UE) for receiving the SMS and reformats the SMS message into IP format (text or encapsulation) for delivery to the UE. A protocol architecture is provided for SMS delivery over WLANs, in particular, for UMTS/CDMA based SMS over WLAN through two alternative mechanisms, i.e., SMS tunneling and SMS proxy, for protocols for the delivery of SMS across the WLAN. The invention enhances standard 802.11 in the context of UMTS and CDMA 2000; as well as other scenarios.

Abstract: The present invention relates to a method and apparatus for performing handover between a universal mobile telecommunication system (UMTS) terrestrial radio access network (UTRAN), and an evolved-UTRAN (E-UTRAN) based system. The wireless communication system includes a UTRAN, an E-UTRAN, a 2G/3G core network, and long term evolution (LTE) core network, and at least one wireless transmit/receive unit (WTRU) including an LTE element and ad 2G/3G element. According to the present invention the WTRU shall be able to handover a call initiated on the UTRAN to the E-UTRAN, and visa versa. The 2G/3G core network and the LTE core network are linked by a Gn interface.

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: Method and apparatus for providing a solution to the handoff problem includes negotiation of new media codes (coders/decoders) for utilization in cases where the two devices involved in the handoff are incompatible. Although mobile IP (MIP) is presently utilized to perform handoff procedures, this technique lacks a trigger mechanism to initiate handoff between two different devices which communicate with two different networks or one common network. In addition, MIP does not address the issue of compatibilities between media types, codes and supported bit rate. The handoff utilizes a session protocol (SIP) message for handoff.
