    摘要: The present invention, generally speaking, provides compact design of optical couplers for combining two differently polarized light beams onto a collimator or splitting a composed light beam into two differently polarized light beams. According to another embodiment, the size of the polarization beam combiner is minimized by using a pair of specially designed fiber collimators that use an asymmetrical sleeve. As a result, a coupler, according to the present invention, uses less components, is of small in size and provides an easy-aligning structure. Further the coupler offers lower optical insertion loss with minimized physical size.

    摘要: Provided is a method for transmitting 1x paging information through an HRPD network and responding to the 1x paging information by a dual-mode MS/AT. After the MS/AT turns to an HRPD network and informs an MSC of related information, if some 1x paging information arrives, the MSC sends a message indicating 1x service arrival to the PCF. An HRPD AN bears the 1x service arrival message that carries calling information sent from the PCF in the 1x service packet to send to the MS/AT. If the user, receiving the 1x service arrival message, chooses to accept a 1x call, the MS/AT terminates the service in the HRPD network and turns to the 1x network to send a “paging response” message to a 1x BS.

    摘要: A method and device for authenticating a MS has an R-UIM by using CAVE Algorithm are provided. The hardware structure of the device includes a cdma2000/HRPD dual-mode chip, a User Identity Module supporting the CAVE algorithm. The dual-mode terminal forms the NAI value with the domain name stored in a memory of the dual-mode terminal in advance by the IMSI. The dual-mode terminal extracts a RAND that is necessary for the calculation of an authentication parameter1 from the Random values included in a Chap Challenge message, instructs the R-UIM card to use the CAVE algorithm to calculate the authentication parameter1 with the RAND and an existing SSD_A in the R-UIM card, and bears the authentication parameter1 by the Result domain of a Chap Response message. With the present invention, the wastes caused by the replacement of R-UIM cards can be avoided.

    摘要: A method for Access Authentication in the High Rate Packet Data Network is proposed in the present invention comprising steps of the AN-AAA receiving the Radius Access Request message sent from the HRPD AN; the AN-AAA judging whether a terminal is a roaming one according to the Network Access ID and transmits the roaming terminal's authentication information to the terminal's home nerwork. If said terminal is a local one, the AN-AAA judges the type of the terminal according to the NAI value. If said terminal is a single-mode one, the AN-AAA works out the Result2 with the MD5 algorithm. if said terminal is in dual-mode, the AN-AAA calculates the Result2 with the CAVE algorithm to compare the Result1 with the Result2.
