20120136938 | Method and Apparatus for Call Proceeding in Call Control of Application Server - The invention discloses a method for call proceeding in call control of an application server, comprising: the application server sending an Offer message to a second party after making a media consultation with a first party; the application server receiving an Answer message sent from the second party, and transforming the Answer message into the Offer message and then sending to the first party, wherein, the Offer message carries a confirmation request for a Precondition state of the first party; the application server receiving the Answer message sent from the first party, wherein, the Answer message carries a confirmation response to the Precondition state from the first party; when determining that the Answer message meets a condition for transforming the Answer message, the application server transforming the Answer message into the Offer message and then sending to the second party. | 05-31-2012 |
20120163579 | Method and application server for obtaining the users' capability in third party call control - The present disclosure provides a method and an Application Server (AS) for obtaining user's capability in Third Party Call Control (3PCC), and the method comprises: when a user performs 3PCC, an AS stores the media information of the user; the AS performs media negotiation with the user according to the stored media information of the user. The application of the present disclosure solves the problem of the high failure probability of media negotiation caused by the current incorrect method for obtaining the user's media capability, and improves the utilization experience of users. | 06-28-2012 |
20120172069 | Method and System for Media Modification - The present invention discloses a method and system for media modification, which is used for solving the problem that it is not considered during media modification whether the user confirmation or precondition of media modification is required, thereby resulting in technical defects, such as possible bearing resource embezzlement, producing redundancy, etc. The present invention regards the 200OK message of Re-INVITE as the confirmed time point of the media addition and/or modification; in the case that there is a precondition and the user confirmation is not required, the time point when the precondition is satisfied is regarded as the confirmed time point of the media component addition and/or existing media component modification; in the case that there is a precondition and the user confirmation is required, the 200OK response message of the Re-INVITE message is regarded as the confirmed time point of the media component addition and/or existing media component modification. | 07-05-2012 |
20120266240 | Method and apparatus for filtering malicious call completion indicator and calling-side network device - A method for filtering a malicious call completion indicator in a CCBS service is provided, in which a calling-side network device rejects the current call request or removes the call completion indicator information from the call request and then forwards the call request, when determining the call request carries the information. The disclosure also provides a corresponding apparatus, which includes a reception unit configured to receive a call request, a detection unit configured to detect the call request and to trigger the rejection unit when determining that the call request carries call completion indicator information and a rejection unit configured to reject the current call request. A calling-side network device is also provided. According to the disclosure, the sequence for accessing the calls from calling subscribers to a called subscriber is well kept, thus assuring fairness of the call access and avoiding preferential call access of malicious subscribers. | 10-18-2012 |
20120282897 | Method and system for accessing completion of call to busy subscriber service based on identity - A method for accessing a CCBS service based on an identity comprises: when receiving a call invite and determining that the call invite includes a call completion indicator, a Terminating Application Server (T_AS) authenticates the identity of a caller initiating the call invite, allows the access of the caller when the identity authentication is passed; and rejects the access of the caller when the identity authentication is failed. A system for accessing a CCBS service based on an identity comprises: a receiving unit, configured to receive a call invite and to trigger the authenticating unit when determining that the call invite includes a call completion indicator; an authenticating unit, configured to authenticate the identity of a caller in the call invite, to trigger the accessing unit when the authentication is passed and to trigger the rejecting unit when the authentication is failed; an accessing unit, configured to access the call from the caller; and a rejecting unit, configured to reject access of the call from the caller. A call access device is provided. The disclosure fully ensures the call order of accessing a calling subscriber to a called subscriber, embodies the call access justification and prevents the preferential call access right of a malicious subscriber. | 11-08-2012 |
20130173831 | PROTECTING CIRCUIT FOR BASIC INPUT OUTPUT SYSTEM CHIP - A protecting circuit for a basic input output system (BIOS) chip of a computer includes a platform controller hub (PCH), an inverting circuit connected to the PCH, a BIOS socket to connect the BIOS chip, and a controlling circuit connected between the inverting circuit and the BIOS socket. The PCH outputs a first signal or a second signal, and a third signal. The inverting circuit outputs an inverted signal with a level contrary to the first or second signal. The controlling circuit receives the first or second signal and the inverted signal, to output a processing signal to the BIOS socket, thereby controlling write-protection states of the BIOS chip. | 07-04-2013 |
20140184348 | CIRCUIT FOR ADJUSTING FREQUENCY OF CRYSTAL OSCILLATOR - A circuit for adjusting frequency of a crystal oscillator includes a basic input output system (BIOS), a platform controller hub (PCH), a buffer, and a capacitor module with a number of capacitors. The crystal oscillator is connected to clock pins of the PCH. An input pin of the buffer is connected to the crystal oscillator. A first end of the each of the capacitors is connected to an output pin of the buffer. A second end of the each of the capacitors is grounded. The buffer includes two enable pins and a control unit controlled by the enable pins. The enable pins of the buffer receive a control signal from the PCH according to the BIOS, and control the control unit to appoint the corresponding capacitor of the capacitor module to be connected to the input pin of the buffer. | 07-03-2014 |
20140297879 | METHOD AND SYSTEM FOR TELECOM NETWORK PROVIDING SESSION SERVICE TO INTERNET - A method for a telecom network to provide a session service to an internet is disclosed. The internet is connected with the telecom network via an access gateway or via an access-side device which has been updated to support an internet application protocol. The method includes: an internet user establishes a session with a telecom user or another internet user through the telecom network. A system for a telecom network to provide a session service to an internet is also disclosed. In the disclosure, the access-side device of the telecom network is updated to enable the access-side device to support the internet application protocol, and the internet and the telecom network are converged, thereby providing the session service to the internet user. The disclosure facilitates the internet user to use the session service. | 10-02-2014 |
20140376544 | METHOD AND SYSTEM FOR CONVERGING CALL - A method for converging a call is disclosed. A non IP-Multimedia-Subsystem (IMS) network is provided with a non IMS network interworking device, by which the non IMS network is converged with a Voice over Internet Protocol (VoIP) network. The method further includes: when the non IMS network determines that a callee receiving a call request is a convergence call user, the non IMS network forwards the call request to the VoIP network; and the VoIP network initiates a call to the callee. A system for converging a call which implements the aforementioned method is further disclosed. The disclosure takes full advantage of the service characteristic of the convergence network, so as to supply users with convenient service access implementation and reduce the service charge. | 12-25-2014 |
