摘要： A method, device and system for obtaining a local domain name are provided. A Dynamic Host Configuration Protocol (DHCP) request of a User Equipment (UE) is received, in which the request carries an option for indicating returning a domain name of a local domain where the UE is located (S200); and the domain name of the local domain where the UE is located is obtained according to the DHCP request, and the domain name of the local domain where the UE is located is carried in a DHCP reply message to be returned to the UE (S202). A device and system for obtaining a local domain name are also provided, which solve the problem that a user is incapable of obtaining a local domain name after full authentication, so that a UE can perform fast re-authentication during a handover, thereby reducing a handover delay and improving the user experience.

摘要： An embodiment of this application discloses a device management method. A first network management device may obtain subscription parameter information, where the subscription parameter information is used to indicate a subscription parameter used during a process of establishing a first subscription session, and the first subscription session is used to indicate a first network device to send subscription data to a network management device managing the first network device. After the first network management device determines that the first subscription session is interrupted, the first network management device may generate a request message based on the subscription parameter information, and send the request message to a network device managed by the first network management device. The request message may include the subscription parameter, and the subscription parameter is used to establish a second subscription session, to establish the second subscription session between the first network management device and the network device managed by the first network management device. It can be learned that the first network management device can establish the second subscription session based on the subscription parameter information, without a need to manually configure the subscription parameter by network management personnel, thereby improving efficiency in re-establishing a subscription session.
