Embodiments of the present invention relate to a snapshot generating method, computer system, and apparatus, which can determine a plurality of virtual machines where an application runs and a deployment server where the plurality of virtual machines is deployed, and send a snapshot instruction to the deployment server of the plurality of virtual machines, so that the deployment server of the plurality of virtual machines can start snapshot operations on the plurality of virtual machines at consistent time points according to the snapshot instruction, so as to generate snapshot files of the plurality of virtual machines at the consistent time points, thereby implementing unified snapshots on the plurality of virtual machines where the application runs and ensuring consistency among backup data of the application.

Snapshot generating method, system, and apparatus

A redundancy method, system, and apparatus, which can acquire first description information of a cloud application needing redundancy, where the first description information includes information about a source virtual machine and a source network which are used at a production site by the cloud application needing redundancy; and can generate second description information of the cloud application needing redundancy at a redundancy site based on the first description information that gives an overall description about the cloud application needing redundancy, where the second description information gives an overall description about the deployment of the cloud application needing redundancy at the redundancy site; and the redundancy site is capable of acquiring the second description information, to recover the cloud application needing redundancy at the redundancy site, thereby implementing redundancy based on a cloud application.

Method, system, and apparatus for cloud application redundancy

A method for implementing communication services includes: after receiving a call request, determining whether a user subscribes to an IP Centrex service and an intelligent network (IN) service according to the obtained subscription information of the user; if the user subscribes to the IP Centrex service and IN service, checking with an application server (AS) whether the call request is for an intra-group call; if the call request is for an intra-group call, performing corresponding service processing according to the checking result to implement discount charging on the intra-group call. By using the method of the present invention, if the user subscribes to the IP Centrex service and the IN service, no conflict occurs between the IP Centrex service and the IN service, and discount charging is implemented on the intra-group call. A network device and a mobile communication system are also provided.

A missing-call short message notification device includes: a main control module for controlling and scheduling other modules; a relay signaling processing module for receiving information sent by the switching device and sending information to the switching device; a short message constructing module for constructing a missing-call short message; a short message sending module for sending the constructed message to the called user. A method for realizing short message notification service for missing calls includes: a called user sets a call forward number to be a missing-call short message notification number; a switching device detects that a call from a calling user to a called user is not put through, and sends information of the calling user to an MCND based on the call forward number; the MCND constructs a missing-call short message based on the information of the calling user and sends the constructed message to the called user.

Device and method for realizing short message notification service for missing calls

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. The method allows low cost and easy operation for the user as well as convenient maintenance for the operator.
