Abstract: Embodiments of this application provide a service data flow processing method for an idle state to reduce a data traffic fee corresponding to the service data flow. The method in the embodiments of this application can include obtaining a service data flow, where the service data flow is a data flow sent by a server to user equipment (UE) through a default bearer, and the default bearer is a bearer set up when a public data network (PDN) connection between the server and the UE is in a connected state. The method may also include determining that an uplink network connection between the UE and the server is in an idle state, and preventing sending of the service data flow, or charging for the service data flow according to a preset charging mode.

Abstract: The present invention includes a page insertion method and device. The method includes: acquiring a page insertion policy; receiving a webpage acquisition request message sent MS; determining first address information corresponding to the webpage acquisition request message; determining second address information of a to-be-inserted page according to the page insertion policy; and adding the first address information and the second address information to a response message and sending the response message to the MS. Thus the MS acquires the to-be-inserted page when acquiring the webpage, reduces a time for service interaction, ensures integrity of the webpage acquired by the MS, thereby effectively improving system performance.

Abstract: The present disclosure provides a directional-traffic statistics collection method, device, and system. A service packet of user equipment is parsed, and whether a feature field in the service packet is valid is determined, to determine whether to report, to a charging server that is configured to perform directional-traffic-based charging on a service provider, an amount of traffic used in a process in which the user equipment uses a service provided by the service provider. According to the solutions in embodiments of the present disclosure, a fraud risk such as fraudulently using a packet feature can be avoided, and accuracy of performing directional-traffic statistics collection on a service provider can be improved.

Abstract: Embodiments of the present invention provide a packet receiving method, a deep packet inspection device and system, which relates to the field of communications. The packet receiving method includes: receiving a service request packet sent by a terminal device, where the packet carries a terminal domain name indicating the terminal device and a server domain name indicating a service server required by the service request; resolving the received server domain name to obtain a service server Internet protocol (IP) address; and discarding the packet if the resolved service server IP address does not belong to the preset service server IP address corresponding to the received terminal domain name in a preset list. Embodiments of the present invention are applied to the processing of the packet.

Abstract: The present invention relates to a method, a system, a gateway, and a server for canceling redirection. When balances of a user are insufficient, a gateway (GW) receives a redirection policy delivered by a policy and charging rules function (PCRF) and redirects the user to a recharging page of a server; after recharging is finished, the server sends a recharging success packet to the GW, and the GW instructs the PCRF to cancel the redirection policy. In this way, after the recharging succeeds, the server directly sends the recharging success packet to the GW, and the GW can immediately instruct the PCRF to cancel the redirection policy after receiving the packet. Therefore, no delay problem of a billing system exists, thereby avoiding that the user is repeatedly redirected to the recharging page of the server during a delay time and enhancing user experience.

Abstract: Embodiments of the present invention provide a service processing method, system and relevant device. The method includes: when a gateway device receives an activation request sent by a user equipment, allocating, by the gateway device, a user IP address to the user equipment; and sending, by the gateway device, user information and the user IP address of the user equipment to an SP server, so that the SP server saves a correspondence between the user IP address and the user information and performs service processing on a service packet according to the correspondence between the user IP address and the user information. By using the present invention, loss of system resources of a gateway device may be reduced.

Abstract: The present invention is applicable to the network access control field and provides a method and apparatus for preventing unauthorized service access. According to embodiments of the present invention, the found IP address is compared with the IP address of the server to which access is requested in the packet, so as to effectively determine a service access request whose packet is tampered with and to terminate the service access request. This effectively solves a problem in which a gateway device cannot charge for a chargeable service due to tampering of a domain name in a packet by a user.
