Abstract: A security authentication for PC client is provided according to the present invention, wherein said method includes: PC client sends a registry request to a server with a user ID and a password; The server makes first authentication based on the user ID and password, if the authentication succeeds, a field used for re-authentication will be created and returned to the PC client through an authentication successful message; When initiating a call, the PC client transmits the user ID and the field used for re-authentication acquired when registered to media gateway controller; The media gateway controller transfers the user ID and field used for re-authentication to the server, which makes second authentication according to the user ID and the field used for the second authentication, if the authentication fails, the call will be rejected, otherwise the call will be accepted and returns information of the called subscriber.

Abstract: A One Number Link You ONLY number is assigned to each subscriber, which identifies the subscriber exclusively. The said subscriber can be an IP subscriber or an ordinary PSTN subscriber. An ONLY Service Server and an ONLY User Server are configured, any ONLY service call initiated by a PSTN subscriber or an IP network subscriber is transmitted to the ONLY Server, and through cooperation between the Service ONLY Server and the ONLY User Server, the call connection control is carried out according to the call control strategy customized by the subscriber in advance, to implement communication between PSTN and IP network subscribers. If the call fails, a new call can be initiated automatically according to the call control strategy list customized by the subscriber in advance. Problems in number, charging, mapping of numbers and subscriber displacement in communication between the PC subscribers and the common phone subscribers can be easily solved.

Abstract: The present invention relates to a method for generating a charge ID in Internet ONLY service, generating the charge ID that includes printable characters using a call ID in the IP gateway; the process is simple and resulted charge ID is absolutely unique. Wherein including: configuring the charge ID including 32 printable characters, each of which is represented with 4 binary bits; taking the call ID including 16 characters, each of which is represented with 8 binary bits; corresponding each call ID character with two charge ID characters, wherein the upper four from eight bits of one of the call ID characters referring to 4 binary bits of one of the charge ID characters, the lower four bits corresponding to 4 binary bits of another charge ID character. Because the scope represented by four binary bits is from 0 to 15, the charge ID characters can exactly correspond one by one relationship with printable characters of 0-9 and A-F.

Abstract: The present invention discloses a implementing method and system for ONLY service that can synretize a PSTN subscriber and an IP network subscriber, the main aspects of invention are: assigning an ONLY number to each subscriber, with which identifies the subscriber exclusively, wherein the said subscriber can be the IP subscriber or the ordinary PSTN subscriber; Configuring an ONLY Service Server and an ONLY User Server, any ONLY service call initiated by the PSTN subscriber or the IP network subscriber being transmitted to the ONLY Server, and through cooperation between the Service ONLY Server and the ONLY User Server, controlling the connection according to the call control strategy customized by the subscriber in advance, to implement communication between the PSTN subscriber and the IP network subscriber. If the call fails, a new call can be initiated automatically according to the call control strategy list customized by the subscriber in advance.
