Apparatus and method for canceling inter-symbol interference in a broadband wireless communication system

Abstract: An apparatus and method for canceling ISI in a broadband wireless communication system are provided. In a transmitter of the broadband wireless communication system, a controller acquires a CP length, a puncturing pattern, and a time sample interval according to a delay spread. A puncturer punctures coded data in the puncturing pattern. An IFFT processor IFFT-processes the punctured coded data and outputs sample data. A CP inserter generates an OFDM symbol by inserting a copy of a last part of the sample data before the sample data. Here, the length of the last part of the sample data is equal to the CP length. A D/A converter converts the OFDM symbol to an analog signal at a sampling rate determined by the time sample interval.

Method for dynamic lossless adjustment of bandwidth of an embedded resilient packet ring network

Abstract: Disclosed is a method for dynamically and losslessly adjusting bandwidth of an embedded Resilient Packet Ring (RPR) ring network, in which dynamic and lossless bandwidth adjustment for an RPR ring network embedded in a Synchronous Digital Hierarchy (SDH)/Synchronous Optical Network (SONET) can be realized through adding a Link Capacity Adjustment Scheme (LCAS) system in the SDH/SONET processing layer. When it is required to increase ring network bandwidth, the bandwidth of the link section between sites on the SDH/SONET processing layer is first increased. Then the LCAS system in the SDH/SONET processing layer is started, and the actual bandwidth of the link on the SDH/SONET processing layer is increased losslessly with the LCAS system. Finally the bandwidth of the ring network on the RPR processing layer is increased. When it is required to decrease ring network bandwidth, the bandwidth of the ring network on the RPR processing layer is first decreased. Then the LCAS system in the SDH/SONET processing layer is started, and the actual bandwidth of the link on the SDH/SONET processing layer is decreased losslessly with the LCAS system. Finally the bandwidth of the link section between sites on the SDH/SONET processing layer is decreased. With the disclosed method, dynamic and lossless bandwidth adjustment for an embedded RPR ring network in SDH/SONET can be realized.

A method for selecting the authentication manner at the network side

Abstract: The emphases of a method for selecting the authentication manner at network side is that HSS returns the authentication information supporting Early IMS authentication manner, or the authentication information supporting Full IMS authentication manner to S-CSCF, or returns the failing information directly to S-CSCF, based on the received authentication information requested in the authentication vector information message from the S-CSCF and the types of the requesting user. If it is the first or the second situation, S-CSCF returns the information for granting access or refusing access to the user based on the authentication result, after authenticating by using the corresponding authentication manner. If it is the last situation, S-CSCF sends directly the information for prohibiting access to UE. The usage of the invention enables the network side to authenticate the user by selecting the accurate authentication manner based on the acquirement of the user, and increase the capability for handling the abnormal events associated with the network side, and the invention is compatible with the existing security protocol farthest at the network side.

A method for reducing interface load of home subscriber server

Abstract: The present invention provides a method for reducing interface load of Home Subscriber Server. After receiving request information from S-CSCF that requests to save name information of the S-CSCF and requests for user subscribing information, HSS first saves name information of the S-CSCF included in the information, then performs a query according to user identification in the information, and returns respond information including user subscribing information back to the S-CSCF directly. The present invention simplifies the steps of querying user subscribing information, optimizes service flow, and reduces interface load of the HSS. In addition, After receiving query request information from the I-CSCF, HSS returns respond information including S-CSCF name and/or information of S-CSCF ability set that can support the strictest service-subscribing requirement of the user to the I-CSCF, further reducing the interface load of HSS. The present invention has no effect on existing network structure and service implementation, and needs not to modify existing interface specification, therefore having good compatibility and expandability.
