Abstract
The embodiment of the present invention provides the method and home gateway of a kind of terminal device renewed treaty IP address, this method comprises: the IP address of terminal device is distributed by the dynamic host configuration protocol DHCP server being located in access net, home gateway (BRG) and access net (NLRG) between disconnecting when, the dhcp message response function of the home gateway starting configuration, execute operations described below: receive terminal device transmission DHCP renew request message after, the home gateway to the terminal device send DHCP renew response message.In the embodiment of the present invention, after disconnecting between home gateway and access net, the dhcp message response function of home gateway starting configuration, after the DHCP for receiving terminal device transmission renews request message, IP address is sent to terminal device and renews message, to guarantee that terminal device can continue to normal use IP address.
Description
Technical field
The present embodiments relate to the communications field more particularly to a kind of methods and home network of terminal device renewed treaty IP address
It closes.
Background technique
Home gateway is the equipment between access network and home network, as shown in Figure 1, home gateway is mainly responsible for
Exchanging between home network internal data and internet data and transformation.
As shown in Fig. 2, in NLRG(Network Located Residential Gateway, network side residence gateway)
Scene in, the equipment for accessing network side provides private net address for home network.This mode can will be big on home gateway
Part three-layer network function is transferred in the equipment of access network side, to simplify the complexity of the hardware and software of home gateway
Degree reduces hardware cost, concentrates progress software release upgrade and more quick deployment new business.
In the scene of NLRG, home gateway is BRG(Bridge Residential Gateway, bridge type residence network
It closes).Home network device can be IPTV(Internet Protocol Television, Internet television), home network
Storage server (NAS) etc.；User equipment can be the equipment such as computer, mobile phone；Family's subnet equipment can be smart home net
Network equipment, domestic safety monitoring network equipment etc..
In the scene of NLRG, the IP address inside home network is distributed by the equipment of access net side, if BRG
Uplink WAN(Wide Area Network, wide area network) interface and access net side connection (such as xDSL, xPON, Ethernet,
The connection types such as WiFi/3G/LTE) there is abnormal interrupt, then the home network device of user expires in dynamic IP addressing rental
Afterwards, renewed treaty operation cannot be carried out from the DHCP Server in access network, so that original business inside home network can be interrupted.
At this time, it will be interrupted inside home network based on the connection that IP agreement is communicated, cause the home network in user's use
Internal data disconnecting is lost, the inconvenience for causing user to use even with user data.
Summary of the invention
