摘要:
A user equipment (UE) operating in a wireless system having at least one base station, communicates with base stations in neighboring wireless systems and conveys information regarding these neighboring wireless systems to the base station of its wireless system, which updates and stores this information for use in handover of Ues (S1, S2, S3). The BS may also obtain updates directly from the base stations of neighboring wireless systems whch may include a diversity of systems such as WLANS, Bluetooth, UMTS, GPRS, etc., and provide to UEs a list of those wireless systems which the UEs need not provide updates to the BS providing the list (S4, S5).
摘要:
The present invention proposes an infrastructure to enable seamless mobility for wireless metropolitan area networks (WMANs) and to provide for management of spectrum and network resources. An WMAN reference model is introduced where the radio resource management (RRM) and handover (HO) sublayer is introduced into the protocol stack. The WMAN management plane is responsible for the RRM and HO management. Several physical and logical network architecture options for WMAN management are proposed.
摘要:
A method and architecture for accessing an IMS (121) over WLANs/WWANs generally, and more particularly over WLANs/WWANs viewed in light of existing related standards is disclosed. More specifically, the invention provides new interfaces enabling IMS (121) access over WLANs/WWANs and an exemplary method and architecture for such an interface.
摘要:
A method for performing an inter-technology handover in a wireless communication system in which a mobile subscriber station (MSS) changes base stations (BS) begins by locating one or more target BSs that the MSS can handover to. The technology used by each target BS is identified, and the technology supported by the MSS is determined. A handover of the MSS is performed to a target BS with which the MSS can communicate.
摘要:
A method and system for switching a radio access technology RAT between two wireless communication systems (110and 120) with overlapping coverage area. RATwith multi-mode WTRU (102) can provide the same service in both networks. Each wireless system transmits an indication of inter-working wireless communication system. WTRU can receive the indication and initiate a handoff to the inter-working system to continue to receive the same service.
摘要:
Method and apparatus for delivering voice/data services within a piconet operating over a limited range or over a WLAN (1803) communicating with 3GPP devices by reformatting data into IP format before delivering to the WLAN (1803). The service is Short Message Service (SMS) (102). Upon receipt of the SMS message, relevant routing information is retrieved. A PDGW (1805) address for the SMS message is identified and sent to the PDGW address which identifies the WLAN use equipment (UE) (1801) for receiving the SMS and reformats the SMS message into IP format for delivery to the UE. A protocol architecture is provided for SMS delivery over WLANs, in particular, for UMTS/CDMA based SMS over WLAN (1803) through two alternative mechanisms: SMS tunneling and SMS proxy, for protocols for the delivery of SMS across the WLAN (1803).
