Abstract: The base station includes a communication circuit for enabling simultaneous communications between a number of ports and a number of the subscriber stations over a given communication channel having multiple sequentially repetitive time slots. An exchange is included to connect the communication circuit to the external communication network ports. A remote-connection process is coupled to the communication circuit by the exchange and by a base-station control channel occupying a selected one of the time slots for monitoring the status of the other time slots. The connection processor causes the communication circuit and the exchange to complete a connection between a given communication network port and a given subscriber station over a time slot assigned in response to the monitored status in accordance with a predetermined assignment routine.

Abstract: A base station in a subscriber communication network for communicating signals between subscriber stations and an external communication network having a plurality of ports. The base station includes a communication circuit for enabling simultaneous communications between a plurality of the ports and a plurality of subscriber stations over a given communication channel having multiple sequentially repetitive time slots, with predetermined time slots being assigned respectively to predetermined subscribers stations; a remote-connection processor for directing communications between the time slot assigned to a given subscriber station and a given external communication network port; and an exchange for connecting the communication circuit to the external communication network ports. The exchange includes a central concentrator for directing signals from predetermined external network ports to predetermined sequentially repetitive time slots in a bit stream generated by the central concentrator, and for directing signals to predetermined external network ports from predetermined sequentially repetitive time slots in a bit stream received by the central concentrator; and the remote-connection processor directs signal transfer between given sequentially repetitive time slots of the bit streams and given sequentially repetitive time slots of the communication channel. The remote-connection processor includes a remote concentrator for directing signals from predetermined remote ports to predetermined sequentially repetitive time slots in a bit stream generated by the remote concentrator and transmitted to the central concentrator, and for directing signals to predetermined remote ports from predetermined sequentially repetitive time slots in the bit stream generated by the central concentrator; and a buffer unit connected to the remote ports for directing signals between predetermined remote ports and predetermined communication channel time slots. The exchange may be located remotely from the communication circuit; and the bitstream may be transmitted between the exchange and the communication circuit by microwave.

Abstract: 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.

Abstract: 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.

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.
