Specific embodiment
The embodiment of the present invention is described in further detail below by specific embodiment combination attached drawing.
Embodiment one：
Foregoing describes the Internet resources due to being accessed needed for different lan devices not in consolidated network,
Different lan devices need to go to access respective Internet resources by different WAN connections." heterogeneous networks " mentioned here at least
There are such two kinds of situations：
The first, the server that Internet resources are provided for different lan devices be located at the different network segments, for example, one family
The corresponding video resource service device of middle set-top box is located in the 14.25.X.X network segments, and provides game on-line service for game machine
Game machine server is in the 104.75.X.X network segments, then the two servers are in heterogeneous networks.
Secondth, the server that Internet resources are provided for different lan devices is located in the same network segment, but different server
Used VLAN (Virtual Local Area Network, virtual LAN) is different, such as online web game corresponds to
VLAN100, but the corresponding VLAN200 of Online Video viewing, in this case, game machine and both lan device institutes of set-top box
The WAN connections used are also different.
Since in the prior art, gateway device is ensuring to access each lan device of itself by corresponding WAN connected references
When Internet resources, more or less itself practical port resource either process resource must all be done and be sacrificed with some.
Moreover, when gateway device not using by the way of port binding come when managing the communication of lan device, it is also possible to cannot to access from
Whole lan devices of body are managed.For these problems, the present embodiment first provides a kind of lan device telecommunication management side
Method refers to Fig. 1 below：
S102, gateway device receive the communication information that lan device is sent.
When lan device accesses its corresponding Internet resources namely accesses the Internet resources needed for it, can be set by gateway
The standby communication information sent to the server for providing Internet resources for characterizing request.Information transmission is carried in the communication information
The device attribute information at end namely the device attribute information for including the lan device for sending the communication information.When gateway device receives
After the communication information that lan device is sent, the communication information can be parsed, get the device attribute letter of information transmitting terminal
Breath.

Under lan device uniquely correspond to, be in order to enable gateway device accurately distinguish access each lan device of itself, the present embodiment
Middle selection device attribute information is because the device attribute information of lan device inherently uniquely can not be counterfeit.It is but true
On, the distinctive information for each lan device for accessing same gateway device can also be uniquely distinguished using other to replace setting
Standby attribute information.For example, self-defined distinctive information can be set to carry out alternate device attribute information, as long as ensureing a gateway device
Under each lan device distinctive information it is unique.For example, same gateway device is accessed by User Defined setting
The distinctive information of set-top box, game machine and laptop is respectively 01,02,03, this should also be as being feasible, only ability
Field technique personnel should be appreciated that when user is using self-defined setting distinctive information, it shall be guaranteed that customized difference letter
Breath has the function of long-term one lan device of unique mark under a gateway device.
Specifically, the lan device is uniquely distinguished according to the MAC Address of lan device, then lan device is set to gateway
Preparation does not need to do the communication information special processing when sending the communication information, and gateway device can directly parse to obtain
Corresponding MAC Address.When using the differentiation information set by User Defined come unique mark lan device, possible lan device
It needs to add the distinctive information of itself in the communication information when communication information is sent.
S104, gateway device determine the corresponding WAN connection modes of the communication information based on the telecommunication management table pre-established.
Gateway device can parse lan device after the communication information for receiving lan device transmission from the communication information
Device attribute information, then according to lan device type, the device attribute of lan device letter in the telecommunication management table that pre-establishes
Mapping relations between breath and WAN connection threes determine WAN connections corresponding with the device attribute information, so as to be assured that
Go out the required WAN connections of the outgoing communication information.
Before the communication information for receiving lan device, gateway device needs to establish telecommunication management table, in order to establish communication tube
Table is managed, gateway device needs to obtain device attribute information, the device type for accessing the lan device of itself.With reference to Fig. 2 to net
The process that pass equipment pre-establishes telecommunication management table is introduced：
S202, gateway device obtain the device attribute information and device type of lan device.
Gateway device obtain lan device device attribute information and device type, be in order to establish device attribute information,
Mapping relations between device type and WAN connection threes.The acquisition of device attribute information and device type can be together
It obtains, can obtain respectively.In a kind of example of the present embodiment, gateway device is obtained by universal plug and play technique
The device type of lan device carries out letter to universal plug and play technique (Universal Plug and Play, UPnP) below
Single introduction：
UPnP is a kind of architecture connected for PC machine with the common peer-to-peer network of smart machine (or instrument), especially
It is in the family.UPnP makes such equipment based on Internet standards and technology (such as TCP/IP, HTTP and XML)
It can connect and cooperate automatically each other, so as to make it possible network (especially home network) to more people.In UPnP
Including various protocols, wherein SSDP (Simple Service Discovery Protocol) refers to Simple Service Discovery Protocol,
The agreement is one of core protocol of UPnP technology.When lan device is linked into gateway device, the notification message of SSDP agreements is sent
(NOTIFY message) declares oneself accessed network.Gateway device can get the equipment class of lan device based on notification message
Type, the process for obtaining the device type of lan device to gateway device below are introduced, and Fig. 3 is illustrated that gateway device obtains
A kind of flow chart of device type：
S302, gateway device receive the notification message that lan device is sent.
After gateway device receives the notification message of lan device transmission, you can confirm that the lan device has accessed net
Network.After this, which there has been the demand for accessing Internet resources, therefore gateway device is it needs to be determined that its device type.
Lan device can with after accessing gateway equipment by Simple Service Discovery Protocol to the notification message of itself.
S304, gateway device parsing notification message and the uniform resource locator for describing file for getting lan device.
URL (the Uniform Resource of the device description file are carried in the location field of notification message
Locator, uniform resource locator), so, gateway device need to only parse notification message, it will be able to obtain lan device
Describe file URL, such as a lan device describe file URL be http//192.168.1.20:49152/des.xml.
The equipment that S306, gateway device access description file acquisition lan device according to the uniform resource locator parsed
Type.
After gateway device, which parses lan device, describes the URL of file, it is possible to lan device be retouched according to the URL
File is stated to access.It is usually " des.xml " to describe file, in file des.xml is described<modelName>It can describe
The type of the lan device, such as gateway device is according to http//192.168.1.20:49152/des.xml access description file
Afterwards, such information can be obtained from description file：“<modelName>STB</modelName>", this represents lan device
Device type be set-top box.
In addition gateway device should first be set before the description file of lan device is accessed according to the URL of lan device with LAN
It is standby to establish TCP (Transmission Control Protocol transmission control protocols) connections.Then pass through HTTP (Hyper again
Text Transfer Protocol, hypertext transfer protocol) mode accesses the corresponding description files of URL, and from description file
The middle device type for obtaining lan device.
The mode of the device attribute information of lan device is obtained for gateway device, in a kind of example of the present embodiment,
Inquiry message can also can be actively sent by gateway device by the device attribute information of lan device active reporting itself and be obtained
To the device attribute information of lan device.In a kind of example of the present embodiment, MAC of the device attribute information for lan device
Location, and MAC Address can be analyzed and acquired by from the notification message sent to gateway device of lan device, so, the present embodiment
In, gateway device can get the device attribute information and equipment of lan device based on universal plug and play technique together
Type.
Other than the scheme of device type or device attribute information is obtained above by universal plug and play technique, gateway
Equipment can also obtain the device type of lan device or device attribute information by other means, for example, being connect by gateway device
The information that lan device is actively sent is received, includes the device type of lan device or device attribute information in the information.Alternatively,
After lan device is linked into gateway device, gateway device actively sends inquiry message to lan device, and lan device is receiving
To after inquiry message, the information comprising device attribute information and/or device type is sent to gateway device according to inquiry message.
S204, gateway device establish telecommunication management table based on device type, the device attribute information got.
Telecommunication management table is mainly used for gateway device during subsequent and inquires the corresponding WAN companies of each lan device
It connects.And correspondence of the different lan devices between different WAN connections is mainly the device attribute information for relying on lan device, sets
What the mapping relations between wide area network connection three used in Internet resources needed for standby type and lan device access determined.
Therefore, it after gateway device gets device type, device attribute information, can be established between the two and WAN connections
Mapping relations, and this mapping relations are recorded by telecommunication management table.
It is understood that gateway device is not to be required for building before the communication information for receiving lan device every time
Vertical telecommunication management table.But created once after a lan device and gateway device establish connection, when lan device accesses net
Before not disconnected after the equipment of pass, gateway device does not need to create telecommunication management table for the lan device again.
S106, gateway device connect outgoing communication information by the wide area network determined.
After gateway device determines WAN connections corresponding with the communication information, it is possible to by the WAN connections by LAN
It is sent out outside the communication information of equipment, so that lan device can access the Internet resources of itself needs by the communication information.
After the communication information reaches gateway device, it may also need to handle some circulation processing inside gateway device
It can be forwarded, intermediate processing procedure may be required for being based on device attribute information.And the device attribute letter of part lan device
Breath, such as the MAC Address of equipment may be long, this leads to gateway device when communication information transmission is carried out, may not
It is very convenient, therefore in a kind of example of the present embodiment, in some specific examples of the present embodiment, telecommunication management table
In further include identification marking, the length of identification marking is less than the MAC Address length of lan device, and respectively with device type, WAN
Connection is unique corresponding.Due to lan device device attribute information between device type there are correspondence, when gateway device exists
During follow-up management, when parsing determines the device attribute information of lan device from the information received, it is possible to really
The device type of the fixed lan device, and then can be that the information sets an identification marking corresponding with device type, conveniently exist
Forwarding information is that selection is connect with the WAN of identification marking.Table 1 shows a kind of telecommunication management table provided in this embodiment：
Table 1
| WAN connections | Identification marking | Lan device type | Device attribute information |
| WAN connections 1 | A | Set-top box | 00:11:22:33:44:55 |
| WAN connections 2 | B | Game machine | 00:11:22:33:22:10 |
It is understood that in the present embodiment, the lan device of same type can have multiple, example under a gateway device
Such as in one family, there are two game machines, the two game machines belong to gaming machine type, but they can possess difference
Device attribute information.In addition, other information can also be included in practical telecommunication management table.Moreover, the present embodiment is also simultaneously
Be not limited in gateway device have to store in the form of above table WAN connections, identification marking, lan device type and
Relationship between unique identifier, if can characterize WAN connections, lan device type and unique identifier three it
Between there are above-mentioned mapping relations.The process that the communication information is forwarded is introduced in gateway device with reference to Fig. 4：
The corresponding knowledge of device attribute information that S402, gateway device determine to carry with the communication information according to telecommunication management table
It does not identify.
Gateway device is parsed from the communication information after the device attribute information of lan device, it may be determined that is gone out the LAN and is set
Standby corresponding identification marking, for example, in a kind of example of the present embodiment, the device attribute information of lan device be user from
Definition, and the device attribute information that gateway device parses is " 00:11:22:33:22:10 ", then according to telecommunication management table
It is " B " that can determine the corresponding identification marking of the lan device.
S404, gateway device set corresponding identification marking for the communication information.
Gateway device stamps identification marking for the communication information, subsequently can simply to identify that the communication information should
Which sent by WAN connections.Such as, in the above-described example, gateway device can set identification to mark in the communication information
Know " B ".
S406, gateway device select corresponding wide area network to connect according to the identification marking in the communication information for the communication information,
And outgoing communication information.
It is true according to the identification marking in telecommunication management table and the communication information when gateway device forwards the communication information
It makes lan device and accesses its required Internet resources need WAN connection to be used, and use corresponding WAN connections by the communication information
It sends.
It is understood that identification marking is the auxiliary information that gateway device is facilitated to carry out actual information forwarding,
Be not realize this embodiment scheme necessary to.
Lan device communication management method provided in this embodiment, gateway device obtain LAN by plug and play technique

S503, home gateway parsing notification message obtain the description file URL of lan device and device attribute information.
Lan device describes the URL of file in the location field of notification message, and home gateway only need to be to notification message
It is parsed, it will be able to obtain the URL that lan device describes file.In addition, home gateway is by parsing the logical of lan device transmission
Know that message can also obtain the MAC Address of lan device from notification message, the MAC Address of such as one lan device is " 00:11:22:
33:44:55 ", home gateway can be using the MAC Address as the device attribute information of lan device.
S504, home gateway and lan device establish TCP connection.
It should be understood that the communication connection that home gateway is established with lan device can also be other than TCP connection
Other any connections with similar action.
S505, home gateway access the device type of the description file acquisition lan device of lan device.
Home gateway obtains the corresponding description files of URL by HTTP modes.Then further according in device description file<
modelName>STB</modelName>The device type for accessing the lan device of itself is got as STB, i.e. set-top box.
Based on aforesaid way, home gateway can also get the device type and its equipment category for accessing the Xbox of itself
Property information.
S506, home gateway establish telecommunication management table.
Based on the first mapping relations shown by table 2 and home gateway according to the device type that notification message is got with
And device attribute information, it is possible to telecommunication management table is generated, such as table 3：
Table 3
| Device type | WAN connections | Identification marking | Device attribute information |
| Set-top box | WAN connections A | A | 00:11:22:33:44:55 |
| Xbox | WAN connections B | B | 00:11:22:33:22:10 |
Although in the present embodiment, home gateway is establishing the first mapping relations at the very start, it is to be understood, however, that,
Home gateway can also create telecommunication management table again after all information is obtained.
TCP connection between S507, home gateway release and lan device
After home gateway is by the device attribute information of lan device and its device type write-in telecommunication management table, family
The TCP connection that gateway is also set up before can discharging with LAN.
S508, lan device determine that the telecommunication management table of home gateway side has safeguarded completion.
When set-top box, Xbox or other lan devices determine that itself TCP connection between home gateway has been released, just
Know that home gateway has safeguarded management information, the service message of itself transmission can be received.
S509, service message is sent to home gateway.
Lan device sends service message to home gateway, to access itself institute after family's gateway forwards service message
The Internet resources needed.
S510, home gateway do message forwarding and prepare.
Home gateway parsing service message obtains the device attribute information of lan device, such as parsing obtains MAC Address and is
“00:11:22:33:22:10”。
According to the correspondence in telecommunication management table between MAC Address and identification marking, home gateway determines and is the report
The identification marking that text should be labeled with is " B ".
S511, home gateway are to server forwarding service message.
WAN connection B outgoing traffic message of the home gateway according to corresponding to identification marking " B " in telecommunication management table.
