This application discloses rule management methods and devices. In an example, a first network device receives first indication information. The first indication information indicates that a terminal is in a suspended state. The first network device sends indication information to a second network device, where the indication information indicates that the terminal is in a suspended state. The second network device determines, based on the indication information, to forgo sending a request for updating a policy and charging control rule and/or a quality of service rule related to the terminal.

Managing a rule of a suspended state terminal

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.

Packet receiving method, deep packet inspection device and system

Disclosed in embodiments of the present invention are a method and an apparatus for assigning an IP address, so as to simplify the process in which a GGSN assigns an IP address, and improve performance of the GGSN. The method in the embodiment of the present invention includes: receiving a request message initiated by the GGSN for creating a service PDP context for a user; obtaining a service list of the user; selecting a service with a different APN out of services recorded in the service; determining whether a same VPN exists in VPNs corresponding to the services with the different APN, and if not, sending a response message of creating a service PDP context for a user to the SGSN, and activating a service PDP context by using an IP address of a default PDP context as an IP address of the service PDP context.
