The disclosure provides a method for supporting multiple time zones in an IP Multimedia Subsystem (IMS). The method comprises: a Proxy Call Session Control Function (PCSCF) network element sends a Session Initiation Protocol (SIP) message including time zone information to a control layer network element exclusive of the PCSCF network element (201); after obtaining the time zone information, the control layer network element receiving the SIP message sends an SIP message including the time zone information to a service layer network element (202); and the service layer network element receives the SIP message sent from the control layer network element and obtains the time zone information included in the SIP message (203). The disclosure also provides a system for supporting multiple time zones, a charging method and a charging system in an IMS. Through the solution of the disclosure, the time zone information can be transferred to each network element above in the IMS, and local time of a user in a call can be included in a Charging Data Record (CDR), thus, the accuracy of charging is improved.

There is disclosed a method of facilitating interaction between users of an electronic community. In an embodiment, the method comprises: reviewing a user activity log for each user in the electronic community; executing a natural language parser to extract significant noun phrases from the user activity log; updating user profiles from the newly extracted noun phrases, based on their usage frequency and importance value; and storing the updated profiles in a user profile and relationship data base; and executing a similarity based clustering algorithm to cluster user profiles, thereby discovering relationships among users and storing them in a user profile and relationship database. The method may further comprise displaying for each user the one or more relationships to which the user is assigned, together with a list of users assigned to the one or more relationships. The method may also comprise storing for each user the relationship to which the user is assigned in a user profile and relationship database.

A Simulator and a simulating method for running a guest program in a host are disclosed. The simulator includes: an initialization device configured for setting content of a hypervisor page table in the host, the hypervisor page table mapping a guest physical address space to a host physical address space. The simulator further includes a binary translation device configured for employing a program logical address to perform a memory access in code translation. The simulator also includes a miss handling device configured for updating a guest translation look-aside buffer by treating a miss in a host translation look-aside buffer caused by the execution of the translated code as a miss in the guest translation look-aside buffer, wherein the host translation look-aside buffer is configured to buffer entries for mapping addresses in a guest program logical address space to addresses in the guest physical address space. The simulator further includes an update tracing device configured for, in response to the update to the guest translation look-aside buffer, perform the update to the host translation look-aside buffer. Also disclosed is a method for running a guest program in a host.
摘要:
A computer-implemented method, apparatus, and article of manufacture for security validation of a user input in a computer network application. The method includes: providing a subset of security rules of a server-side protection means to a pre-validation component deployed at a client side, so as to enable security validation of a user input on the client side by the pre-validation component; validating the user input based on at least one of the security rules; determining, in response to detecting a user input violation and that a violated security rule has not been provided to the pre-validation component, the user as a first class of users; determining, in response to detecting the user input violation and that the violated security rule has been provided to the pre-validation component, the user as a second class of users; and performing different security protection actions to the first and second class of users.

A switch circuit is provided. The switch circuit may include a first transistor having a source terminal to accept an input signal, a drain terminal to provide an output signal, and a gate; a power supply providing a gate voltage. The switch circuit may also include a circuit to couple a switch signal to the gate, wherein the circuit turns the first transistor ‘off’ for all values of the input signal when the switch signal is ‘low.’ A programmable gain amplifier (PGA) is also provided. The PGA may include an input stage having an input node to couple an input signal, and an output node to provide a gate signal, at least a first gain stage including a resistor and a switch circuit as above. A differential gain amplifier may be included to provide an output signal from the gain signal.

A method of transmitting a video stream over an IP network. The method includes encoding a source video into a plurality of packets. The method also includes measuring a real-time transmission status of a current set of the plurality of packets. The method also includes mapping a utility curve for the video which reflects utilities of the video at corresponding sending rates. The method also includes calculating a target sending rate for a next set of the plurality of packets according to the real-time transmission status of the current set of the plurality of packets and the utility curve. The method also includes determining a proper strategy to meet the target sending rate for the next set of the plurality of packets.

A method, a device, and a system for offloading network traffic are provided, which are applied in the field of mobile communications. An offloading device located before a Serving General Packet Radio Service Support Node (SGSN) receives a data stream of a user sent by a base station, obtains an offloading policy of the user from the offloading device and/or obtains the offloading policy of the user from a policy server, and forwards the data stream according to the offloading policy. Accordingly, the offloading device can obtain the corresponding offloading policy according to the data stream sent by a forwarding plane, send a data stream of low value, low real-time performance requirement, or low priority to the Internet or another specific networks, and send a data stream of high value, high real-time performance requirement, or high priority to high-value devices, thereby reducing the networking cost.
