In the embodiment of the present invention, contextual model switching signal is the signal that node device is sent, current for prompt terminal Scene information, and the relevant configuration information suitable for current scene, terminal is by obtaining the scene mould that node device is sent Formula switching signal come learn current scene go forward side by side market scape pattern configurations work, to meet requirement of the current scene to terminal.Its In, the mode of node device broadcast contextual model switching signal can include directional broadcasting and non-directional is broadcasted, and directional broadcasting is then It is using terminal as broadcast object, contextual model switching signal is broadcast to terminal, non-directional broadcast is then not specified broadcast pair As contextual model switching signal is broadcast to the working region of node device by ground, make the terminal for being operated in node device working region Voluntarily obtain contextual model switching signal and carry out adaptability contextual model configuration.

In specific implementation, terminal beginning is in a kind of holding state, it is not necessary to goes monitoring external environment information, receives Signal scanning work is proceeded by during trigger signal.The trigger signal that the embodiment of the present invention refers to is that one kind is opened for triggering terminal The signal of beginning signal scanning operation, it can include making the signal of terminal jingle bell and make the display screen of terminal from screen state of going out It is transformed into the signal of bright screen state, terminal is started at least one of signal of scan function, for example, terminal is in non-mute state Under, when receiving from other people call signal, ringing tone prompting should be carried out, then, terminal detects to be currently needed for carrying out ringing tone During prompting, the signal in scanning work region is immediately begun to.

In the specific implementation, the signal in working region is broadcasted by node device, it can be including a variety of, in meeting work Under the scene of work, contextual model claimer can be by manipulated nodes equipment come the configuration of requirement terminal and the corresponding scene of scene Pattern, correspondingly, the signal of node device broadcast should include at least contextual model switching signal.In order to be different from other types letter Number, the embodiment of the present invention can add contextual model switching mark in contextual model switching signal, for terminal recognition, scene Pattern switching mark can be the code in a kind of data structure；The scene mould being switched to clearly express terminal to need Formula, the embodiment of the present invention can add the related data for specifying contextual model, such as scene mould in contextual model switching signal Formula code, contextual model numbering or each parameter value of contextual model etc..If for example, signal node of the signal of node device broadcast Structure is：Message length+execution requires ID+ execution values, and wherein message length represents the length of self-defining data, and execution requires ID generations Table signal type, then correspondingly, the message structure of contextual model switching signal can be：Message length+scene handover operation ID+ scenes switch required value, and wherein scene switching required value corresponds to certain contextual model, such as mute, jingle bell, vibration, open air, Scene switching required value can be the code of contextual model or contextual model to the relevant parameter of demanding terminal.

In order to establish correspondence between terminal and node device, relevant agreement can be established to support, e.g., assisted Addition, which performs, in view requires ID with performing desired correspondence, then node device broadcast carries the signal for performing and requiring ID Afterwards, terminal can go out perform the type for requiring terminal required by ID to be performed by protocol identification；This is added in the protocol to hold Row requires the correspondence of at least one code that carries into execution a plan and carry into execution a plan corresponding to ID, then the letter of node device broadcast In number further carry perform require ID two level carry into execution a plan code when, terminal can carry into execution a plan code to hold according to two level Row task.For example, when the signal that terminal scanning arrives is " message length+scene handover operation ID+ scenes switch required value ", terminal It can determine that the signal is used to prompt contextual model and requires terminal to coordinate current scene to cut according to scene handover operation ID Change to and switch the corresponding contextual model of required value with scene.

It is further alternative, control list can also be included in agreement, the node device of control terminal is supported for recording. For example, the ACL control lists for support node apparatus control terminal can be set, specifically, terminal can select node to set Standby mark, the mark of node device is added in ACL control lists.Wherein, for the information as node device mark MAC Address, node device title or the feature string defined for node device, the terminal that can include node device connect When receiving the contextual model switching signal for carrying above type node device identification, it is believed that send the contextual model switching signal Node device is the node device that terminal protocol is supported, terminal can be according to the feelings of the contextual model switching signal switching terminal Scape pattern.In the specific implementation, content in the ACL control lists of terminal can by the user of using terminal come set, change and Addition, can also voluntarily be set, changes and added by terminal.

In specific implementation, when terminal receives trigger signal, the current broadcast sound volume of terminal can be arranged to mute, and Signal in scanning work region at the same time, starts timing at this time, if terminal is obtained available for switching feelings in preset time The contextual model switching signal of scape pattern, then switching contextual model immediately, and work under the contextual model being switched to；It is another Aspect, if failing to obtain any contextual model switching signal in preset time, cancels the mute setting of terminal, and makes terminal Return to the broadcast sound volume required by initial contextual model.For example, can be 3 seconds with preset time, then, scan operation is triggered When, the broadcast sound volume of terminal is arranged to mute, scan operation be triggered after 3 seconds in, terminal is obtained available for switching feelings During the contextual model switching signal of scape pattern, the contextual model that is switched to required by contextual model switching signal；Scan operation quilt Behind 3 seconds after triggering, terminal fails to obtain the contextual model switching signal available for switching contextual model, then cancels terminal Mute setting, and the broadcast sound volume for making terminal return to required by initial contextual model.
