Background technology
Video communication service claims visual telephone service again, is a kind of communication service of transmitting both call sides image and voice signal on IP network simultaneously.In general, the terminal equipment that video communication service uses, it is broadband video telephone, external form is similar with common video telephone, but its special feature is to have Duoed a LCDs than plain old telephone, above display screen, disposed a camera, and built-in microphone, thereby make the user can realize video calling.It directly inserts IP network in LAN (Local Area Network, local area network (LAN)), ADSL multiple modes such as (Asymmetric Digital Subscriber Line, Asymmetrical Digital Subscriber Lines).As long as the user plugs telephone wire, netting twine, carry out the few parameters configuration and can use.
At present described video telephone is configured, common method comprises following several:
Prior art one: terminal is using DHCP (Dynamic Host Co nfigurationProtocol, Dynamic Host Control Protocol) when obtaining the IP address, in DHCP option with on the address of " configuration device ".Reference flowchart as shown in Figure 1.
The shortcoming of prior art one is: during actual the construction, need increase Dynamic Host Configuration Protocol server newly in the position that terminal inserts, perhaps transform the existing Dynamic Host Configuration Protocol server in this position, the construction cost height.
Prior art two: just set the domain name of " configuration device " when terminal is dispatched from the factory, obtain the address of " configuration device " by domain name mapping.Reference flowchart as shown in Figure 2.
The shortcoming of prior art two is: during actual the construction, in the same name server compass of competency, have the operator of the different configuration servers of a plurality of needs.Need be provided with the domain name of configuration server this moment at different situations, require every batch of terminal to press the place of delivery customization, for example: xx city telecommunications and xx city Netcom all use the name server of this province, and xx city telecommunications is different with the configuration server of xx city Netcom, so can not use same domain name.Therefore cause production cost to uprise.
Prior art three: when terminal is obtained the IP address by physical circuit, learn user related information, then this terminal of notice " configuration device " configure according to its physical circuit.Reference flowchart as shown in Figure 3.
The shortcoming of prior art three is: during actual the construction, need to transform the network equipment of operator, the construction cost height.
In sum, still there is the high problem of construction cost in prior art to the configuration of terminal.
