Abstract: A pyram-shaped deep-sea pressure-resistance shell and a design method therefor. The shell comprises a conical shell, an annular combined shell, a cylindrical shell, a flange bolt, and a perforated thick plate; a bottom end of the conical shell is connected with a top end of the annular combined shell, the conical shell being in communication with an interior part of the annular combined shell; the perforated thick plate blocks the bottom end of the annular combined shell, the perforated thick plate and the annular combined shell being connected by means of multiple flange bolts; the cylindrical shell is disposed inside the annular combined shell, a lower end of the cylindrical shell being inserted in a gap between the annular combined shell and the perforated thick plate.

Abstract: Disclosed is a method for implementing authentication of high rate packet data (HRPD) services, applicable to multi-mode networks including IS95/CDMA2000 1x and CDMA2000 HRPD networks. The method includes an Access Terminal (AT) using the user information in the User Identity Module (UIM) as the user identifier and starting an authentication in accordance with the Extended Authentication Protocol (EAP). A Mobile Switching Center (MSC)/Visiting Location Register (VLR) obtains a random number and a first authentication number based on the user identifier, and the AT calculates a second authentication number based on said random number. The MSC/VLR compares the first authentication number with the second authentication number to determine whether they are consistent. If consistent, the authentication is successful. Otherwise, the authentication is aborted. With the disclosed method, authentication can be made by using the original MSC and HLR/AC in the CDMA IS95 or CDMA2000 1x network.

Abstract: Embodiments of the invention include a universal integrated mobile gateway used in wireless communication networks to interconnect different networks, comprising: AMP for data collocation and state management for other modules, CCM for data switching network management (together with other modules) and control data frame switching between modules, CDP for storage and management of relay resource and global shared resources, SPCs for processing services in different networks, and network interface; CCM is connected with AMP, CDP, and SPCs through HDLC protocol; SPCs are connected to the network interface through TCP/IP protocol. The embodiments improve normalization and operability of network interconnection, facilitate unified settlement between different networks, and enhance overall resource utilization of the networks.
