Agent equipment is kept at local forming device list after resolving the notification message of all terminal equipments listened to.Further, agent equipment, in snoop procedure, also will be responsible for the maintenance to list of devices, comprises newly-built, the amendment of list of devices, deletion, renewal etc.As when there being new terminal device request to add network, the attribute information of this new terminal equipment is added in list of devices; When existing terminal equipment asks to add network again, to update the equipment list according to the attribute information of this existing terminal equipment.In this method, the existing terminal equipment of indication refers to and added network and its device attribute information has been kept at the terminal equipment in list of devices; When this terminal equipment adds network again, its attribute information may change, and when agent equipment listens to the information after this change, by revising or delete original attribute information, increases the mode of new attribute information and to update the equipment list.In addition, this notification message generally also comprises the message such as IP address, application port of terminal equipment.
S103: what receiving control apparatus sent searches message, using search information broadcast to record in list of devices, as the terminal equipment of pre-selection device, and set up conversational list according to the path of broadcast.
When a certain terminal equipment wishes to control other-end equipment, can send with or without the terminal equipment that a certain service can be provided search (Search) message (due to this certain terminal equipment be send service request and send after finding the terminal equipment that this service can be provided control request equipment, thus can be described as control appliance).This is searched message and comprises the service request of control appliance and the attribute message such as IP address, application port of control appliance.When watching the program on intelligent television as wished as user by smart mobile phone, smart mobile phone can send as control appliance and search message, this searches the service request that message comprises " intelligent television for me provide audio-video frequency content " of this smart mobile phone, and its IP address, application port etc.Agent equipment is monitored this and is searched message, the local list of devices preserved of traversal, this is searched information broadcast to record in the list of devices in step 102 the terminal equipment as pre-selection device, and according to broadcast path set up session (Session) table.The list of devices preserved due to agent equipment this locality includes all terminal equipments in network, thus pre-selection device refer to except control appliance other may become all terminal equipments of controlled device.The conversational list set up generally comprises the IP address, protocol type, application port etc. of terminal equipment, conversational list have recorded in " path " of control appliance and controlled device information interaction, is the basis that agent equipment forwards the interaction message of control appliance and controlled device.
S104: what receive pre-selection device feedback searches response message, will search response message send to control appliance according to conversational list.
Pre-selection device receive control appliance search message after, according to searching the service request comprised in message, judge whether to provide a certain service for control appliance, send search response message.With to search message relative, this is searched response message and comprises whether providing the service request response message of a certain service, the IP address, application port etc. of pre-selection device.Agent equipment is monitored this and is searched response message, will search response message send to control appliance according to conversational list.
S105: when control appliance is according to searching after response message determines controlled device in pre-selection device, according to the interactive information between conversational list transparent transmission control appliance and controlled device.
After control appliance receives and respectively searches response message, according to searching of feeding back of each pre-selection device response message determines can the controlled device of respond services request.
Further, in order to more understanding equipment and its function, control appliance also will obtain device descriptive information and the service description information of controlled device.As mentioned before, all can send a notification message when any terminal device request adds network, this notification message comprises device description message pointer, and is broadcast to other-end equipment via agent equipment.Thus this control appliance obtains the information of device description and service describing according to this device descriptive information pointer received, concrete, the device description sent according to conversational list transparent transmission control appliance by agent equipment and service describing solicited message, and the device description of feedback and service describing response message.Wherein, transparent transmission refers to transparent transmission, and that is, the information no matter agent equipment transmits how, is only responsible for, by needing the information transmitted to be sent to destination node, ensureing the quality of transmission simultaneously, and not processing the information of transmission.Descriptor comprises: device descriptive information and service description information.Wherein, device descriptive information is mainly used in performance to equipment, parameter, the service etc. that can provide be specifically described; Equipment may can provide different services, can provide the services such as video playback, picture presentation, online reading as smart mobile phone, thus the service description information specific descriptions information of serving for providing the difference of same equipment.
After equipment descriptor and service description information, in the reciprocal process of follow-up control appliance and controlled device, agent equipment is according to its interactive information of conversational list transparent transmission.Interactive information refers to all information in whole reciprocal process.
Generally speaking, after the descriptor obtaining equipment and information on services, control appliance at least comprises with communicating of controlled device: the control request that control appliance sends to controlled device, comprise subscribe request, renewal request, the event request such as to cancel subscriptions and show a series of service action requests of request, the response message corresponding with this service action request, query interface request and response message corresponding with it.
Further, when control appliance sends action request message to controlled device, agent equipment, according to the interactive information between conversational list transparent transmission control appliance and controlled device, mainly comprises:
According to conversational list, the operational order that control appliance sends is sent to controlled device;
Connection between control appliance and controlled device, is initiatively send the request of control by control appliance, sets up after controlled device accepts.The operational order that control appliance sends is exactly the control request wanting to control controlled device of accusing that control equipment sends to controlled device.Agent equipment listens to this control request, and sends to controlled device by conversational list.
Control appliance is sent to according to the execution result that controlled device returns by conversational list.
As the response message of aforesaid operations instruction, the execution result returned by controlled device is back to control appliance according to " path " in conversational list.
Illustrate with PAD and intelligent television below.
As user wish the TV programme play on PAD in intelligent television time, PAD sends the request controlling intelligent television to intelligent television as control appliance, intelligent television returns the execution result of this request correspondence as controlled device, controlling, refusing to control as accepted.
Further, after the connection establishment of control appliance and controlled device, controlled device provides corresponding service to control appliance.Because completing of a certain service is a process, this process may corresponding a series of state.As in video playback service, this service may be in start to play, in buffering, play in, play a series of state such as end, different states has its corresponding variate-value.
Thus, in a kind of implementation of this method, control appliance periodically initiatively sends variable query request to grasp the state of service at any time, and agent equipment is according to the interactive information between conversational list transparent transmission control appliance and controlled device.Concrete, when control appliance sends query interface request to controlled device, the variable query request that control appliance sends according to conversational list by agent equipment sends to controlled device; When controlled device feeds back current variable states to controlled device, the current variable state that controlled device returns according to conversational list by agent equipment sends to control appliance.After service completes, control appliance can also send renewal request to controlled device, cancel subscriptions and ask.
In the another kind of implementation of this method, when service state changes, controlled device notifies control appliance by event, and controlled device is according to this event determination current service status.When not having control appliance to subscribe to this service, event is broadcasted by controlled device.
Further, the compatible multiple different user mode access of the agent equipment in this method, as the access way of PPPoE and IPoE.Concrete, for PPPoE access user, the agent equipment in the present invention supports that PPPoE message seals off dress, and as required, Reseal is PPPoE message or IPoE message; For IPoE access user, the agent equipment in this method supports that IPoE message seals off dress, and as required, Reseal is PPPoE message or IPoE message.At present, gateway device common in family comprises the home gateway of the home gateway of the route pattern supporting IPoE authentication mode and the bridge mode of support PPPoE authentication mode, the DLNA agent functionality that this method provides can pass through software simulating on existing home gateway, and then realize the mutual discovery of home intelligent terminal, content shares and multi-screen interactive, avoids the replacement of home gateway in current network.
With each terminal equipment support of the prior art and after opening DLNA function, carry out DLNA connection, and requiring that terminal equipment must be in same local area network (LAN) and compare, this method adds agent equipment in order to monitor the interactive information between each terminal equipment, transparent transmission terminal equipment; Due to existing with the form of intermediary of agent equipment, can all messages of transparent transmission network internal, thus terminal equipment is not limited in same local area network (LAN), and the realization of the agent functionality of this agent equipment is without the need to changing existing hardware facility, no matter can be realized by the form of software, be thus that the gateway device of route pattern or the gateway device of bridge mode all can retain and without the need to changing.
Further, when control appliance roams into far-end, as when company goes to work, when free time is wanted to play the program of family intelligent television by mobile phone, (far-end in this method refers to that control appliance is positioned at different local area network (LAN)s from other-end equipment, for the network internal in method shown in Fig. 1), the embodiment of the present invention additionally provides a kind of method that smart machine carries out Long-distance Control, as shown in figures 2 a and 2b, the method comprises: by the interactive information between no-protocol tunnel transparent transmission control appliance and controlled device.
The general principle in this no-protocol tunnel is based on IP (IPinIP) clean culture in the no-protocol determining source/destination IP address, stateless IP.Usually generic route encapsulation (GenericRoutingEncapsulatio is adopted with tunneling technique in prior art, being called for short GRE) agreement etc. realizes comparing, tunneling technique in this method is without the need to adopting any agreement, thus the complex process by protocol validation, foundation, connection, cancellation can also be avoided, comparatively simple and can dispose, be a kind of long-range connection scheme of stateless of simplification.When message is by no-protocol tunnel transmission, only need be outer to complete tunnel encapsulation at original message by source/destination IP address encapsulation at head end, tail end carries out opening dress, and each network element searches routing table on the way, common unicast forwarding.Retain heading and the load of original message, inherit mark or reset message flag, not changing original message content.
In this method, control appliance and being still alternately of controlled device are realized by agent equipment, and the implementation of network internal still with reference to the method shown in figure 1, then can monitor forwarding information by no-protocol tunnel between control appliance and agent equipment.Fill different for the encapsulation of message and opening that are transparent to network internal and network-external by agent equipment, specific implementation is as follows:
