Embodiment

For convenience of description, in the description of following embodiment of the present invention, will be to set forth as example such as the portable terminal of mobile phone, personal digital assistant etc.Should be appreciated that portable terminal among the present invention be not limited to above-mentioned both, but can also comprise any other equipment that portable computer, Tablet PC etc. have mobile computing and mobile communication ability.

In addition, in the description of following embodiment of the present invention, will be with the representative illustration of bluetooth (Blue Tooth) technology as the short-range wireless communication mode.Yet, it will be appreciated by those skilled in the art that to be applicable to that the invalid communication mode of short range of the present invention is not limited to Bluetooth technology, but can also comprise such as other any suitable short-range wireless communication modes such as WiFi.

Below, will be in conjunction with the accompanying drawings, describe each execution mode of the present invention in detail.

At first, Fig. 3 shows the schematic diagram according to the application scenarios 300 of one embodiment of the present invention.As shown in Figure 3, in portable terminal 1 112, portable terminal 2 114 and portable terminal 3 116 residing zones, suppose to take place natural calamity and cause the communications infrastructure such as original base station to damage and the forfeiture communication capacity.At this moment, portable terminal 1 112, portable terminal 2 114 and portable terminal 3 116 are distributed in and can use in the scope that communicates such as short-range wireless communication modes such as bluetooths.

When the user found natural calamity to occur and can't get in touch with the external world with the conventional wireless mobile communication, electric weight how as far as possible to save portable terminal manages to carry out efficient communication with extraneous rescue personnel simultaneously then became two The key factor.Suppose that each user outwards sends wireless signal with total power this moment, then, do not stop at portable terminal under the situation of searching mobile communication network service that the electric weight of preserving in the battery will exhaust very soon because the communications infrastructures such as base station have damaged.Like this, even repaired the communications infrastructures such as base station after a while, subscriber equipment also can't be got in touch with the external world.

According to an illustrative embodiment of the invention, having proposed a kind of rescuer of support utilizes near quilt person of rescuing of mobile terminal to search and guiding rescuer location by the technical scheme of the person of rescuing present position.Simultaneously, according to the embodiment of the present invention, a kind of technical scheme of being utilized near the rescuer the mobile terminal to search to save the electric quantity consumption of portable terminal simultaneously by the person of rescuing supported has been proposed also.According to the embodiment of the present invention, portable terminal can be provided with two kinds of patterns: rescuer's pattern and the quilt person of rescuing pattern.Hereinafter, above-mentioned two kinds of patterns are described in further detail.

The quilt person of the rescuing pattern of portable terminal is meant that portable terminal (for example passes through the short-range wireless communication interface, bluetooth) constantly send the distress signal that receives for the portable terminal that is in rescuer's pattern, thereby the portable terminal of rescuer's pattern is caught the pattern of this distress signal to the external world.For example, the quilt person of rescuing that need obtain succouring is when finding to occur situation such as natural calamity, after attempting using the conventional wireless mobile communication and the external world to get in touch failure, for example can be by the person of rescuing by importing a string particular sequence to the portable terminal of oneself or, selecting to make the portable terminal of oneself to enter pattern by the person of rescuing by menu option.Perhaps, in the time can't being imported this particular sequence by the person of rescuing (for example, injured or other fortuitous events), this portable terminal can can't detect under the situation of conventional mobile communication signal in specified time interval, enters the pattern by the person of rescuing.The user can self-defined this specified time interval.

In addition, can also have such situation, be in by the portable terminal of the person's of rescuing pattern and at a time detected conventional mobile communication signal, then portable terminal can eject information to the user, and whether inquiry continues to remain in by the person of rescuing pattern.At this moment, portable terminal can remain in the pattern by the person of rescuing in response to the user imports particular sequence, perhaps can return to conventional mobile communication.

Alternatively, in case detect the portable terminal that is in rescuer's pattern, then notified to the user by cues such as sound or vibrations by the portable terminal of the person's of rescuing pattern.In addition, alternatively, portable terminal changes the intensity of sound/vibration according to detected signal strength signal intensity and self residual electric weight.

Rescuer's pattern of portable terminal refers to that portable terminal passes through short-range wireless communication interface (for example, bluetooth) and constantly sends search signal to the external world, the pattern of replying so that the quilt person's of rescuing portable terminal is caught this search signal.With respect to the quilt person of rescuing pattern, rescuer's pattern is used by the rescue team member usually, and ordinary people perhaps out of danger also can use rescuer's pattern to search for the people that other need be rescued.For example, and by the person of rescuing mode class seemingly, the user can select to enter rescuer's pattern by a string particular sequence of input or by menu option.Portable terminal comes the portable terminal of the quilt person of the rescuing pattern of searching near by short-range wireless communication interface (for example, bluetooth) afterwards.Alternatively, in case detect the portable terminal that is in by the person's of rescuing pattern, then the portable terminal of rescuer's pattern is notified to the user by cues such as sound or vibrations.In addition, alternatively, rescuer's portable terminal changes the intensity of sound/vibration according to detected signal strength signal intensity.

Should be appreciated that, described herein can be used alternatingly that two kinds of signals are the signal for finding that the other side is sent when looking for mutually by distress signal that is sent by the person's of rescuing enable mode and the search signal that sends by rescuer's pattern.In other execution modes according to the present invention, can there be above-mentioned two kinds of signals simultaneously, perhaps only there is one of them, as long as the portable terminal of two kinds of patterns can be found each other.

According to the embodiment of the present invention, a plurality of can set up between by the portable terminal of the person's of rescuing pattern network (such as, realize with Ad Hoc technology), be in by the portable terminal of the person's of rescuing pattern by in this network institute overlay area all and form a virtual group 110 (as shown in Figure 3).In virtual group, on behalf of all portable terminals in this virtual group, need elect a portable terminal to communicate with the external world, promptly outwards send distress signal, and in response to receiving the replying of described distress signal, and detect the portable terminal that is in rescuer's pattern.All the other portable terminals in the virtual group no longer send distress signal except that regularly sending the heartbeat message that carries this status information of mobile terminal.Like this, can reduce the electric quantity consumption of each member in the virtual group and then the stand-by time of prolongation virtual group integral body.Above-mentioned status of mobile terminal information comprises the dump energy of portable terminal or the signal strength signal intensity of portable terminal etc.

Send heartbeat message and have two purposes: on the one hand, portable terminal can be known current which portable terminal and the state thereof of existing by heartbeat message in the virtual group in virtual group; On the other hand, the quantity of portable terminal and state (for example change in virtual group, some portable terminal is because electric weight is crossed low and shutdown etc.) time, the state of virtual group can be refreshed by the data in the last heartbeat message that between portable terminal, sends.

According to the embodiment of the present invention, can two kinds of patterns of " being activated by the person of rescuing " and " by the person's of rescuing economize on electricity " will further be categorized as by the person's of rescuing pattern.Be meant the residing pattern of portable terminal that is in the outside transmission distress signal that is elected the portable terminal of the person's of rescuing pattern from above-mentioned by the person's of rescuing enable mode.The quilt person of rescuing energy-saving mode is only to need regularly the outwards residing pattern of portable terminal of those quilts person of rescuing pattern of transmission heartbeat message.Be in by the power consumption of the portable terminal of the person's of rescuing energy-saving mode well below being in by the portable terminal under the person's of rescuing enable mode.

Should be appreciated that when setting up virtual group at first the portable terminal in the virtual group need be consulted each other to elect the first round outwards to send the portable terminal of distress signal by pre-defined rule.According to pre-defined rule, if the current activation condition that is no longer met rule definition by the portable terminal of the person's of rescuing enable mode, for example the portable terminal electric weight of Ji Huoing is crossed low etc., then need to conduct an election again among the portable terminal of the portable terminal of the current enable mode in virtual group and energy-saving mode, represent the portable terminal in the virtual group outwards to send the next round distress signal by the portable terminal of the new quilt person of rescuing enable mode thereafter.

As shown in Figure 3, this moment, portable terminal 1 112 was in the enable mode by the person of rescuing, and portable terminal 2 114 and portable terminal 3 116 are in the energy-saving mode by the person of rescuing.As can be seen from Fig. 3, portable terminal 1 112 is set up with the extraneous portable terminal 130 that is in rescuer's pattern by the short-haul connections interface and is communicated by letter.

Hereinafter, will be further explained in detail embodiments of the present invention in conjunction with the operation interface example of the various operator schemes shown in Fig. 4.

Shown in Fig. 4 A, show the operation interface that is in by the portable terminal under the person's of rescuing enable mode, in this pattern, outwards sent distress signal by the portable terminal under the person's of rescuing enable mode, whether there is the portable terminal that is in rescuer's pattern with around detecting.At this moment, this is in and can be comprised following content in the interface of mobile terminal under the person's of rescuing enable mode:

1) pattern 402: expression portable terminal present located operator scheme is the quilt person of rescuing enable mode.Exist a plurality of by the person's of rescuing situation under, is a plurality ofly at first set up virtual group, and elect a portable terminal and it is set to the enable mode by the person of rescuing, and remaining portable terminal is set to the energy-saving mode by the person of rescuing by pre-defined rule by the person of rescuing.Yet,, this quilt person of rescuing can be set to enable mode by the person of rescuing in that in particular cases (that is, can't being found when being in by other portable terminals of the person's of rescuing pattern) of a quilt person of rescuing only arranged near the quilt person of rescuing.

2) detect 404: the sign ID of portable terminal that represents the detected rescuer's pattern of portable terminal of the current quilt person of rescuing pattern.When be in detected rescuer's portable terminal by the portable terminal of the person's of rescuing enable mode after, then send a notification message, with the sign ID of the portable terminal of notifying this rescuer's pattern to other portable terminals of setting up the quilt person of the rescuing energy-saving mode in the virtual group.Then, for being in by the portable terminal of the person's of rescuing energy-saving mode, shown in Fig. 4 B, the displaying contents of " detecting 404 " this project is the ID of the portable terminal under the detected rescue pattern of portable terminal of the quilt person of the rescuing enable mode of setting up virtual group with it.

3) signal strength signal intensity 406: the communication signal strength between expression current mobile terminal and the detected portable terminal.

4) dump energy 408: the dump energy of current mobile terminal battery.

5) audio communication 410: the audio communication between current mobile terminal and the detected portable terminal is managed.

6) message communicating 412: the audio communication between current mobile terminal and the detected portable terminal is managed.

7) tone/vibration 414: select the type of notice prompting, promptly can prompting be set and be set to sound type or oscillatory type according to the user.

To by the description of the person of rescuing enable mode, be appreciated that the implication of every setting in the user interface of the quilt person of rescuing energy-saving mode shown in Fig. 4 B, Fig. 4 C and rescuer's pattern with reference to above, do not repeat them here.Above-mentioned Fig. 4 A only is schematically to the interface of Fig. 4 C, and also unrestriced.

With reference now to Fig. 5 to Fig. 8,, from rescuer's pattern and the flow process that is illustrated respectively by the person's of rescuing pattern two aspects according to the method for embodiment of the present invention.

As shown in Figure 5, show the flow chart that is used for according to one exemplary embodiment by the communications of Mobile Terminals method 500 under the person's of rescuing pattern.

As shown in Figure 5, at step S502 place, portable terminal is set to by the rescue pattern.For example, meeting with emergency needs relieved user to start portable terminal to enter the pattern by the person of rescuing.Can exist multiple mode activating by the person's of rescuing pattern, such as, activate by menu option or by importing a string particular sequence.

At step S504 place, be in by one or more portable terminal of the person's of rescuing pattern and communicate by the short-range wireless interface each other, so that initialization network and set up a virtual group.Particularly, be in by the portable terminal of the person's of rescuing pattern and can send detection signal, finding other portable terminals that are in by the person's of rescuing pattern, thereby form virtual group.

After having set up virtual group, at step S506 place, according to pre-defined rule, operation conducts an election between the portable terminal that constitutes this virtual group, be about to one of described portable terminal and be set to enable mode, and all the other portable terminals are set to the energy-saving mode by the person of rescuing by the person of rescuing.

Particularly, each portable terminal can obtain each status of mobile terminal information in the virtual group, and this state information is represented the communications of Mobile Terminals ability.According to an embodiment of the invention, state information can be the dump energy of portable terminal, and wherein when the dump energy of portable terminal was maximum in virtual group, this portable terminal was set to the enable mode by the person of rescuing; When the dump energy of portable terminal was not maximum in virtual group, this portable terminal was set to the energy-saving mode by the person of rescuing.According to another implementation of the invention, state information can be the signal strength signal intensity of portable terminal, and wherein when the signal strength signal intensity of portable terminal was maximum in virtual group, this portable terminal was set to the enable mode by the person of rescuing; When the signal strength signal intensity of portable terminal was not maximum, this portable terminal was set to the energy-saving mode by the person of rescuing.

Alternatively,, be in by the portable terminal of the person's of rescuing enable mode and outwards send distress signal, whether have the portable terminal that is in the rescue pattern with around detecting at step S508 place.In an illustrative example, can be adjusted the power and the frequency of outside transmission distress signal by the portable terminal of the person of rescuing pattern: the self residual electric weight, detect the intensity etc. of the signal of the portable terminal that is in rescuer's pattern according to following factor.For example, when detecting faint rescuer's mode type mobile terminal signal, can be strengthened the portable terminal that the power that himself sends distress signal detects rescuer's pattern by the portable terminal of the person's of rescuing pattern, search by the possibility of the person's of rescuing mode type mobile terminal to increase the rescue personnel; And when using smaller power can not detect the portable terminal of rescuer's pattern, can suitably strengthen the intensity that sends distress signal.

Alternatively, at step S510 place, judged whether to detect the portable terminal that is in rescuer's pattern by the portable terminal of the person's of rescuing enable mode.

If detected this type of portable terminal at step S510 place, then at step S514 place, to be sent notification signal to the portable terminal of the quilt person of rescuing energy-saving mode by the portable terminal of the person's of rescuing enable mode, ID with the portable terminal that will be in rescuer's pattern informs that other are in by the portable terminal of the person's of rescuing energy-saving mode, and sets up communication at the portable terminal of rescuer's pattern and between by the portable terminal of the person's of rescuing pattern.Particularly,, its pattern can be changed into enable mode, so that communicate with the portable terminal of rescuer's pattern by the person of rescuing when being in when being received the ID of the portable terminal that is in rescuer's pattern by the portable terminal of the person's of rescuing energy-saving mode.

Then, the whole operation flow process finishes after step S514.

In other embodiments, find by the person's of rescuing probability in order to improve the rescuer, when the small-signal of the portable terminal that is detected rescuer's pattern by the portable terminal of the person's of rescuing enable mode, can also activate other portable terminals that are in by the person's of rescuing energy-saving mode, and make and a plurality ofly outwards sent signal together by the portable terminal of the person's of rescuing pattern, to increase the probability of being found by the rescue personnel.

Alternatively, after step S508, if continue to send during the specified time interval under the situation that distress signal but do not met with a response (that is, the result among the step S510 is a "No"), then operating process enters step S512.

At step S512 place, to being detected by the parameters of the portable terminal of the person's of rescuing enable mode, to determine whether this portable terminal satisfies the condition as enable mode: if satisfy, then operating process is back to step S508, the portable terminal of the current quilt person of rescuing enable mode keeps the enable mode by the person of rescuing, and carries out the detected activity of next round.Otherwise operating process is back to step S506, so that from all portable terminals that satisfies predetermined activation condition that is made new advances by election the portable terminal of the person's of rescuing pattern.

Be to be understood that, alternatively, a time interval can be set, after the described time interval of experience, be continued outwards transmission distress signal, thereby avoid the situation that causes electric weight to exhaust with high-power transmission distress signal within a short period of time by the portable terminal of the person of rescuing enable mode.For example, can continue to send 5 minutes distress signal every 30 minutes, can also detect according to other modes of employing are set by being arranged so that by the portable terminal of the person's of rescuing enable mode.

Through after the step S512, operating process or return step S506 and conduct an election is again perhaps returned step S508 and is carried out next round and detect, and subsequent process repeats no more with mentioned above identical.

Should be appreciated that, alternatively,, the signal strength signal intensity of each portable terminal can also be remained on the signal strength signal intensity that other portable terminals with the least possible quantity communicate in order further to be reduced in the overall power consumption of the portable terminal in the virtual group.For example, in described virtual group, reduction is in by the signal strength signal intensity of the portable terminal of the person's of rescuing energy-saving mode gradually, and described signal strength signal intensity is remained on the signal strength signal intensity that can communicate with at least one other portable terminal in the described virtual group.

Hereinafter, will further describe the state transitions of electing as shown in Figure 5 in the step 506 with reference to figure 6 and Fig. 7.

Fig. 6 is the state transition diagram that election process according to one exemplary embodiment is shown.

There is following state during the election process:

Conventional state S0, the expression portable terminal initially enters by the state of the person's of rescuing pattern;

Negotiation state S1 exists around the expression portable terminal is found to be in by behind other portable terminals of the person's of rescuing pattern, holds consultation each other with election by the status of mobile terminal of the person's of rescuing enable mode;

State of activation S2: expression is in the enable mode by the person of rescuing; And

Electricity-saving state S3, expression is in the energy-saving mode by the person of rescuing.

As shown in Figure 6, status of mobile terminal may be switched between above-mentioned 4 kinds of states.Under state S0, portable terminal will outwards send signal and whether have identical node to detect.Described same node point is meant that the user has selected to enter the portable terminal by the person's of rescuing pattern.If portable terminal detects identical node continuous n time, then this status of mobile terminal is converted to negotiation state S 1 from conventional state S0, shown in arrow C among Fig. 6 01.Otherwise if do not detect, then to remain in conventional state S0 constant for portable terminal.

In practice, may exist user's oneself portable terminal to be set to be existed the situation of sequencing by the time of the person's of rescuing pattern, at this moment, the difference that portable terminal enters the emergency mode time point may cause occurring following situation: may have a plurality of portable terminals among the regional extent that short-range wireless communication can cover, and before specific portable terminal is selected to enter by the person's of rescuing pattern, other portable terminals in this zone have been set up a virtual group, and have elected by the portable terminal of the person's of rescuing enable mode and other portable terminals and be set to the energy-saving mode by the person of rescuing.

Under this state, after entering by the person's of rescuing pattern, portable terminal detects when the portable terminal of virtual group has been set up in existence on every side, and described portable terminal only needs to keep in touch with one of portable terminal of having set up virtual group; And when carrying out the next round election, described portable terminal is added virtual group get final product.

Negotiation state S1 can enter according to the rule that is provided with to come by selecting energy-saving mode to enter electricity-saving state S3 (shown in arrow C 13), perhaps by selecting enable mode to enter state of activation S2 (shown in arrow C 13).In electricity-saving state S3,, then enter conventional state S0 (shown in arrow C 30) if portable terminal does not detect the node of enable mode.In state of activation S2, when the user selects to withdraw from enable mode, then shown in arrow C 20, enter conventional state S0.

From state diagram shown in Figure 6 as can be known, under the state of emergency, need relieved personnel's portable terminal following state may occur:

1) among the regional extent that short-range wireless communication can cover, found one or more other portable terminals, form virtual group and being set to it with self by the person's of rescuing enable mode or by the person's of rescuing energy-saving mode.

2) among the regional extent that short-haul connections can cover, when finding other portable terminals through specified time interval, then current portable terminal can be set to the enable mode by the person of rescuing, outwards send distress signal to detect the external rescue personnel every special time, perhaps remain in conventional state S0 shown in Figure 6, so that around special time detects, whether there is other same node point.

As shown in Figure 7, show the flow chart of the election process between the quilt person of rescuing portable terminal according to one exemplary embodiment.

At first, at step S702 place, be in by the portable terminal of the person's of rescuing pattern and can outwards send detection signal, in the short-haul connections scope, whether there are other portable terminals that are in equally by the person's of rescuing pattern to detect, form a virtual group by being in by the portable terminal of the person's of rescuing pattern so that set up one.

At step S704 place, if find other portable terminals, then at exchange state information each other, so that obtain each status of mobile terminal information in the virtual group, such as the sign ID of portable terminal, remaining battery capacity, each other signal strength signal intensity etc.
