  • Publication number: 20120020262
    Abstract: The present invention discloses a method for sending non-3GPP2 system information in a high rate packet data system, which comprises: setting a non-3GPP2 SystemInfo Transfer message in an HRPD system; generating the non-3GPP2 SystemInfo Transfer message and sending it to a multimode mobile terminal supporting both the HRPD system and the non-3GPP2 system when a network side of the HRPD system determines that the multimode mobile terminal is located in an area covered by the HRPD system together with the non-3GPP2 system. The present invention also discloses a method for responding to the non-3GPP2 system information. The present invention further discloses apparatuses for realizing the above-mentioned methods. The present invention is simple and practical.

  • Publication number: 20120008566
    Abstract: The present invention discloses a method for transmitting a non-Third Generation Partnership Project 2 (3GPP2) message in a High Rate Packet Data (HRPD) system, comprising: a transmitting end encapsulates the non-3GPP2 message in a non-3GPP2 Info Transfer message according to a preset format of the non-3GPP2 Info Transfer message and transmits the non-3GPP2 Info Transfer message to a receiving end through an HRPD air interface (301); and the receiving end decapsulates the non-3GPP2 Info Transfer message obtained from the HRPD air interface, according to the preset format of the non-3GPP2 Info Transfer message, to obtain the non-3GPP2 message (302). The present invention further discloses a system for transmitting the non-3GPP2 message in the HRPD system. The present invention realizes the transmission of the non-3GPP2 message in the HRPD system.

  • Patent number: 7725724
    Abstract: The present invention discloses a digital signature scheme based on braid group conjugacy problem and a verifying method thereof, wherein a signatory S selects three braids x?LBm(l), x??Bn(l), a?Bn(l), and considers braid pair (x?,x) as a public key of S, braid a as a private key of S; Signatory S uses hash function h for a message M needing signature to get y=h(M)?Bn(l); generating a braid b?RBn?1?m(l) randomly, then signing M with a and b to obtain Sign(M)=a?1byb?1a; a signature verifying party V obtains the public key of S, calculating the message M by employing hash function h, obtaining the y=h(M); judging whether sign(M) and y, sign(M)x? and xy are conjugate or not, if yes, sign(M) is a legal signature of message M; the present invention reduces the number of braids involved and the number for conjugacy decision without reducing security, thereby improving the operation efficiency of signature.

  • Publication number: 20100112993
    Abstract: A method, a device, and a system for message identification are provided. The method for message identification includes: receiving an MO message carrying a calling identifier and a calling party address; obtaining a VMSC address of a subscriber corresponding to the calling identifier; and determining whether the calling party address is consistent with the obtained VMSC address or not, and if not, the MO message is a spoof message. The device and the system are a device and a system corresponding to the method for message identification, which are capable of realizing effective identification of message spoofing behaviors.

  • Publication number: 20080270299
    Abstract: A WAP gateway and a method for implementing billing control for prepaid subscribers include: a wireless application protocol WAP gateway interacts related information with a billing system according to different service requests of the prepaid subscriber, and collects and controls related fees according to the interacted information. The method effectively realizes real-time billing, and neatly configures a billing policy, so as to realize flexible billing based on various fee rates and satisfy requirements of the flexible billing of carriers. The method also ensures high efficiency and reliability of the billing by saving billing sessions in the gateway in a certain period of time. When a big file is downloaded, if the flow is pre-deducted and the user does not enjoy substantial service due to various abnormities, the method can roll back the flow.

  • Publication number: 20070227537
    Abstract: A method for configuring a protocol for use in providing a medical treatment to a patient is provided. A protocol may be selected for configuration, the protocol being associated with a medical treatment having a process flow including multiple steps. A protocol template may be created for the protocol, including selecting and arranging flowchart components to create a graphical flowchart representation of the process flow, and defining one or more variables for one or more steps in the process flow. The one or more variables may be linked to one or more existing objects such that when the protocol is executed, the existing objects are automatically accessed to facilitate execution of the protocol.
