When participation adjacent communication is within the network coverage to UE but is not to provide service by the same base station, system can To determine that (such as session management, authorization are recognized safely by control message exchange flow between UE, base station and core net node Card etc.) realize adjacent communication control.In addition, can also direct exchange of signaling between UE.

For the adjacent communication under public safety scene, when in the UE for participating in adjacent communication some UE is covered in network Within lid, then at least one public safety UE in this part of UE can for participate in adjacent communication other not in the network coverage Under UE relay wireless resource management control signaling.

For the adjacent communication under public safety scene, if public safety UE not within network coverage, UE Between can directly carry out control plane communication.Public safety UE can be established and be tieed up by preconfigured radio resource Protect adjacent communication.In addition, if public safety UE supports public safety radio resource management function, can also directly manage public The radio resource allocation of safe adjacent communication.

As it can be seen that having the demand of adjacent service relaying (ProSe relay) for the adjacent communication under public safety scene, i.e., One public safety terminal has can be as the ability need of the adjacent service relay node of other public safety terminals.

Demand with regard to ProSe relay includes the following aspects:

For supporting the public safety terminal of ProSe relay (to have the public peace of adjacent service relay node ability Full terminal), user or system can enable/go to enable the ability of the public safety terminal as adjacent service relay node；

The communication of public safety terminal as adjacent service relay node is not influenced by relaying.

For one needs to carry out the terminal of adjacent communication using ProSe relay, how to find in adjacent service After the first step that node is progress ProSe relay.But the prior art has not found the realization side of adjacent service relay node Case.

Specific embodiment

To solve the problems, such as how to find adjacent service relay node, technical solution provided in an embodiment of the present invention is as follows: (in the embodiment of the present invention, the terminal at control point is referred to as UE_ to the terminal at each terminal control point centered on by centered on Con relay capabilities information) is reported, the relay capabilities information determination that UE_con is reported according to each terminal can be used as in adjacent service After the terminal of node, in turn, UE_con is obtained and is sent the identification information that can be used as the terminal of adjacent service relay node.It is not The terminal of UE_con receives and saves the identification information that can be used as the terminal of adjacent service relay node, when needs pass through neighbouring clothes It, can be according to the terminal that can be used as adjacent service relay node of preservation when business relay node initiates relayed communications to Correspondent Node Identification information, select used in adjacent service relay node.

Technical solution provided in an embodiment of the present invention is particularly suitable for public safety field, but not only limit is applied to public peace Full field.

In addition, technical solution provided in an embodiment of the present invention, can apply the adjacent service communication in the not network coverage Under scene, it can also apply in the case where there is the adjacent service communication scenes of the network coverage.

Technical solution provided in an embodiment of the present invention is described in detail below in conjunction with attached drawing.

In following declarative procedure, first it is illustrated respectively from the side UE_con and the implementation of the terminal side of non-UE_con, Finally implement to be illustrated from the side UE_con and the cooperation of the terminal side of non-UE_con, but this does not imply that the two must cooperate reality It applies.In fact, also solving respectively when the terminal side of the side UE_con and non-UE_con is performed separately in the side UE_con, non-UE_ The problems of terminal side of con can obtain superior technique effect when only the two is used in combination.

Fig. 1 show a kind of discovery method of adjacent service relay node provided in an embodiment of the present invention, and this method is specific Including operating as follows:

Step 100, UE_con obtain the identification information that can be used as the terminal of adjacent service relay node, wherein can be used as The terminal of adjacent service relay node is that UE_con is determined according to the relay capabilities information that terminal reports.

Wherein, if terminal supports ProSe relay, and its ProSe relay function is enabled (enabled to open), then The terminal can be used as adjacent service relay node.

Wherein, if UE_con itself can be used as adjacent service relay node, what UE_con was obtained can be used as neighbouring clothes It may include the identification information of UE_con in the identification information of the terminal of business relay node.

Step 110, UE_con send the identification information of the terminal that can be used as adjacent service relay node obtained.

In, UE_con may receive the relay capabilities information that each terminal reports successively, often receive in a terminal The relay capabilities information of report then reports whether the terminal of the relay capabilities information can be used as neighbour according to relay capabilities information determination Nearly service relay node.Correspondingly, UE_con maintenance can be used as the identification information of the terminal of adjacent service relay node, specifically may be used With but be not limited only to tabular form safeguard can be used as adjacent service relay node terminal identification information.If UE_con can It then include UE_con's in the identification information that can be used as adjacent service relay node of its maintenance as adjacent service relay node Identification information.In the embodiment of the present invention, so-called maintenance includes at least following two layers of meaning: (1), UE_con save determining make For the identification information of the terminal of adjacent service relay node；(2), when meeting deletion condition, UE_con deletes the end saved The identification information at end.

The particular content of deletion condition is set according to actual needs.Such as: assuming that terminal is both in it can be used as adjacent service It is reported when node and indicates its relay capabilities information that can be used as adjacent service relay node, also do not can be used as in adjacent service It is reported when node and indicates its relay capabilities information that not can be used as adjacent service relay node, then when UE_con is according in terminal The relay capabilities information of report knows that (i.e. it can not when the relay capabilities for the terminal that can be used as adjacent service relay node change As adjacent service relay node), it is believed that meet deletion condition.Assuming that terminal only reports instruction, it be can be used as in adjacent service After the relay capabilities information of node, but do not report when it not can be used as adjacent service relay node instruction its not can be used as it is neighbouring The relay capabilities information of service relay node, then UE_con can be used as the end of adjacent service relay node for each of preservation Timer is arranged in the identification information at end, when the timer times out, then it is assumed that meet deletion condition.

Wherein, the relay capabilities of terminal refer to that terminal could be used as adjacent service relay node.

Correspondingly, UE_con is specifically to obtain the adjacent service relaying that can be used as completely or partially safeguarded to save in step 100 The identification information of the terminal of point.

Based on process flow shown in FIG. 1, UE_con both can passively receive the relay capabilities information that terminal reports, can also With indicating terminal to report relay capabilities information.If UE_con indicating terminal to report relay capabilities information, can periodically indicate Terminal reports relay capabilities information.Below with two preferred implementations for example:

(1) UE_con periodic broadcast relay capabilities information reporting instructs, so as to receive the relay capabilities information reporting The terminal of instruction reports it to relay ability information to UE_con.

That is, UE_con instructs explicit informing terminal that its is reported to relay ability information, this hair by relay capabilities information reporting Bright embodiment is not defined the specific signaling format for carrying the instruction of relay capabilities information reporting.

(2) UE_con is regular or irregular broadcasting center control point identification information, so as to receive the center control point The terminal of identification information reports it to relay ability information to UE_con.

That is, UE_con implicitly informs that terminal reports it to relay ability information, the present invention by center control point identification information Embodiment is not defined the specific signaling format for carrying center control point identification information, in implementation, can arbitrarily broadcast Center control point identification information is carried in message.It under this implementation, is pre-configured with or makes an appointment, so that terminal is being received It can be reported to relay ability information to the UE_con that the center control point identification information indicates after to center control point identification information.

It should be pointed out that the above implementation for only illustrating UE_con and obtaining the relay capabilities information of each terminal, But it is not limited only to implementation exemplified as above.

Based on above-mentioned any side UE_con embodiment of the method, there are many specific implementations of process flow shown in FIG. 1, It enumerates below wherein several:

(1) for UE_con after receiving relay node identification request information, obtaining and sending can be used as adjacent service relaying The identification information of the terminal of node, specific:

After UE_con receives the relay node identification request information that requesting terminal is sent, acquisition reports relay capabilities information The identification information of all terminals that can be used as adjacent service relay node in terminal, and making for acquisition is sent to the requesting terminal For the identification information of the terminal of adjacent service relay node.

In each embodiment of the present invention, so-called requesting terminal is needed through adjacent service relay node to communication pair Initiate the terminal of relayed communications in end.

As described above, the relay capabilities information determination that UE_con is reported according to terminal can be used as adjacent service relay node Terminal, and safeguard the identification information that can be used as the terminal of adjacent service relay node.It is therefore, so-called that " acquisition reports relaying energy The identification information of all terminals that can be used as adjacent service relay node in the terminal of force information ", i.e., " obtaining all of maintenance can The identification information of terminal as adjacent service relay node ".

(2) UE_con is obtained after receiving the relay capabilities solicited message for particular terminal and is sent particular terminal In can be used as relay node terminal identification information, it is specific:

Wherein, the value of proportion threshold value can be set according to specific communication scenes, and the present invention is not construed as limiting.

In addition, the ratio in the adjacent terminals quantity of the terminal quantity and UE_con that report relay capabilities information reaches ratio Under the premise of threshold value, UE_con can periodically or irregularly obtain and broadcast it is all in the terminal for reporting relay capabilities information can The identification information of terminal as adjacent service relay node.

As described above, the relay capabilities information determination that UE_con is reported according to terminal can be used as adjacent service relay node Terminal, and safeguard the identification information that can be used as the terminal of adjacent service relay node.It is therefore, so-called that " acquisition reports relaying energy The identification information of all terminals that can be used as adjacent service relay node in the terminal of force information ", i.e., " obtaining all of maintenance can The identification information of terminal as adjacent service relay node ".

(4) UE_con can actively obtain and send the identification information that can be used as the terminal of adjacent service relay node, tool Body:

When reporting the terminal quantity of relay capabilities information to reach terminal quantity threshold value, UE_con acquisition reports relay capabilities to believe The identification information of all terminals that can be used as adjacent service relay node in the terminal of breath, and that broadcasts acquisition can be used as neighbouring clothes The identification information of the terminal of business relay node.

Wherein, the value of terminal quantity threshold value can be set according to specific communication scenes, and the present invention is not construed as limiting.

In addition, under the premise of reporting the terminal quantity of relay capabilities information to reach terminal quantity threshold value, UE_con can be with It obtains periodically or irregularly and broadcasts all adjacent service relay nodes that can be used as in the terminal for reporting relay capabilities information The identification information of terminal.

As described above, the relay capabilities information determination that UE_con is reported according to terminal can be used as adjacent service relay node Terminal, and safeguard the identification information that can be used as the terminal of adjacent service relay node.It is therefore, so-called that " acquisition reports relaying energy The identification information of all terminals that can be used as adjacent service relay node in the terminal of force information ", i.e., " obtaining all of maintenance can The identification information of terminal as adjacent service relay node ".

(5) UE_con can actively obtain and send the identification information that can be used as the terminal of adjacent service relay node, tool Body:

UE_con periodically acquires all adjacent service relay nodes that can be used as in the terminal for reporting relay capabilities information The identification information of terminal, and broadcast the identification information for the terminal that can be used as adjacent service relay node that each period obtains.

As described above, the relay capabilities information determination that UE_con is reported according to terminal can be used as adjacent service relay node Terminal, and safeguard the identification information that can be used as the terminal of adjacent service relay node.It is therefore, so-called that " acquisition reports relaying energy The identification information of all terminals that can be used as adjacent service relay node in the terminal of force information ", i.e., " obtaining all of maintenance can The identification information of terminal as adjacent service relay node ".

That is, UE_con periodically acquires the mark of all terminals that can be used as adjacent service relay node of maintenance Information, and the identification information for the terminal that can be used as adjacent service relay node that each period obtains is broadcasted, without considering Whether meet some requirements.

It is planted in implementation in above-mentioned (three), (four), (five), optionally, UE_con can be used as neighbour what broadcast obtained When the identification information of the terminal of nearly service relay node, the instruction of relay capabilities information reporting is carried in same broadcast message, So as to report the terminal of relay capabilities or the changed terminal of relay capabilities not yet upon receiving the message, not only obtain The identification information that can be used as the terminal of adjacent service relay node is taken, is referred to also according to the relay capabilities information reporting carried in message Order reports it to relay ability information.

UE_con can also safeguard the proximity relations information of each terminal.UE_con both can passively be received in each terminal The identification information of the adjacent node of report can also report instruction with periodic broadcast proximity relations, so as to receive the proximity relations The terminal of instruction is reported to report the identification information of its adjacent node to UE_con.

In the embodiment of the present invention, optionally, UE_con can send relay capabilities information reporting by a broadcast message Instruction and proximity relations report instruction.

Correspondingly, can also there are following (six) or (seven) to plant implementation.

(6) UE_con combination proximity relations acquisition of information and transmission can be used as the mark of the terminal of adjacent service relay node Know information, specific:

After UE_con receives the relay node identification request information of requesting terminal transmission and the identification information of Correspondent Node, If determining that Correspondent Node is terminal and requesting terminal and Correspondent Node report neighbouring section according to the identification information of Correspondent Node The identification information of point, UE_con judgement can be used as in the terminal of adjacent service relay node with the presence or absence of requesting terminal and communication pair Hold common adjacent node, if it does, UE_con obtain can be used as in the terminal of adjacent service relay node requesting terminal and The identification information of the common adjacent node of Correspondent Node, and it is sent to requesting terminal, if it does not, UE_con acquisition can be used as The identification information of the adjacent terminals of requesting terminal in the terminal of adjacent service relay node, and it is sent to requesting terminal.

Wherein, if can be used as common there is no requesting terminal and Correspondent Node in the terminal of adjacent service relay node Adjacent node, it is also possible to which there are a kind of situations: it can be used as in the terminal of adjacent service relay node also the not neighbour of requesting terminal Nearly node, then UE_con can plant implementation according to above-mentioned (one) and be handled.

After UE_con receives the relay node identification request information of requesting terminal transmission and the identification information of Correspondent Node, If determining that Correspondent Node is terminal and requesting terminal reports the mark of adjacent node to believe according to the identification information of Correspondent Node Breath, Correspondent Node do not report the identification information of adjacent node, and UE_con is obtained in the terminal that can be used as adjacent service relay node The identification information of the adjacent node of requesting terminal, and it is sent to requesting terminal.

Wherein, it is also possible to which there are a kind of situations: can be used as in the terminal of adjacent service relay node also without requesting terminal Adjacent node, then UE_con can according to above-mentioned (one) plant implementation be handled.

(7) UE_con combination proximity relations acquisition of information and transmission can be used as the mark of the terminal of adjacent service relay node Know information, specific:

After UE_con receives the relay node identification request information of requesting terminal transmission and the identification information of Correspondent Node, If determining that Correspondent Node is network and requesting terminal reports the mark of adjacent node to believe according to the identification information of Correspondent Node It ceases, whether includes being somebody's turn to do in the identification information for the adjacent node that UE_con is reported according to the terminal that can be used as adjacent service relay node The identification information of network, judgement can be used as in the terminal of adjacent service relay node with the presence or absence of the end in the network coverage End, if it does, UE_con obtains the terminal in the terminal that can be used as adjacent service relay node in the network coverage Identification information, and requesting terminal is sent to, if it does not, UE_con obtains the terminal that can be used as adjacent service relay node The identification information of the adjacent node of middle requesting terminal, and it is sent to requesting terminal.

Wherein, UE_con can believe according to the mark for the adjacent node that the terminal that can be used as adjacent service relay node reports Breath, judgement can be used as the terminal of adjacent service relay node whether in the coverage area of above-mentioned network.If can be used as neighbouring In the identification information for the adjacent node that the terminal of service relay node reports include above-mentioned network identification information, then judge its with The network node is neighbouring；If the terminal that can be used as adjacent service relay node do not report adjacent node identification information or Do not include the identification information of above-mentioned network in the identification information of the adjacent node reported, then judges its not covering in the network node Within the scope of lid.

In the embodiment of the present invention, the identification information for the adjacent node that terminal reports can be the mark of terminal (i.e. adjacent terminals) Know information, is also possible to the identification information of network.Wherein, the identification information of network can be base station level, i.e., by base station Identification information of the identification information as network；It is other that the identification information of network is also possible to carrier-class, as each operator Network distribute a network identification information；It can also be the corresponding network in same division region according to region division network Distribute identical identification information；Etc., this is not limited by the present invention.

The Correspondent Node of terminal can be terminal, be also possible to network.

If the identification information for the adjacent node that terminal reports is the identification information of network, show that the terminal is in the net In the coverage area of network.Therefore, if the Correspondent Node of requesting terminal is network, UE_con is relayed according to can be used as adjacent service In the identification information for the adjacent node that the terminal of node reports whether include the network identification information, judgement can be used as neighbouring clothes It is engaged in the presence or absence of the terminal in the network coverage in the terminal of relay node, if it does, this can be used as neighbour by UE_con The identification information of the terminal of nearly service relay node is sent to requesting terminal, and requesting terminal can be used as neighbouring clothes by this The terminal of business relay node, which is communicated to the network, initiates relayed communications.If it does not, UE_con acquisition can be used as adjacent service The identification information of the adjacent node of requesting terminal in the terminal of relay node, and it is sent to requesting terminal.

In the above-mentioned any embodiment of the present invention, UE_con is also possible to either preconfigured terminal according to predetermined The selected terminal of rule.

It if it is preconfigured terminal, can be both pre-configured with, can also be pre-configured with by user by network side.Example Such as, under the group scene of adjacent communication, user configuration is center control point as the terminal of group leader (group owner).Example again Such as, under the adjacent communication scene of public safety field, one group of user is equipped with public safety terminal, can configure wherein some use Control point centered on the terminal that family is equipped with.

If it is the terminal selected according to pre-defined rule, the pre-defined rule of selected UE_con can have it is multiple, such as: it is predetermined Rule indicates, in the terminal for selecting one group of adjacent communication always, control point centered on the most terminal of adjacent terminals quantity.Again Such as: pre-defined rule instruction, the terminal failure or its adjacent terminals quantity at control point centered on user specifies When lower than threshold value, control point centered on the terminal for selecting adjacent terminals quantity most, otherwise, the terminal for selecting user to specify are made For center control point.

Fig. 2 show the discovery method of another adjacent service relay node provided in an embodiment of the present invention, this method tool Body includes following operation:

Step 200, the identification information for receiving the terminal that can be used as adjacent service relay node that UE_con is sent.

The identification information for the terminal that can be used as adjacent service relay node that step 210, preservation receive.

It is the process flow of the neighbouring terminal of UE_con in the embodiment of the present invention, shown in Fig. 2.UE_con neighbouring terminal side In embodiment of the method, for technical characteristic identical with the side UE_con, specific descriptions are referred to the implementation of the side UE_con method Example.

Process flow based on Fig. 2, neighbouring terminal can also report it to relay ability information to UE_con with UE_con.

If neighbouring terminal knows which terminal is UE_con in advance with UE_con, can actively be reported to UE_con Relay capabilities information.

It, can be in the relaying for receiving UE_con transmission if requesting terminal cannot know which terminal is UE_con in advance After ability information reports instruction or center control point identification information, relay capabilities information is reported to UE_con.Specifically, with After UE_con neighbouring terminal receives the relay capabilities information reporting instruction of UE_con transmission, relay capabilities are reported to UE_con Information, alternatively, after the terminal neighbouring with UE_con receives the center control point identification information that UE_con is sent, on UE_con Report relay capabilities information.

Wherein, the terminal neighbouring with UE_con receives the instruction of relay capabilities information reporting or the center of UE_con transmission After the identification information of control point, relay capabilities information both can be directly reported, can also be reported after judgement meets scheduled condition Relay capabilities information.

If reporting relay capabilities information after judgement meets scheduled condition.Specifically, judge this terminal whether first It is secondary receive relay capabilities information reporting instruction, or it is upper once report relay capabilities information after, the relaying energy of this terminal Whether power changes, if receiving the instruction of relay capabilities information reporting for the first time, or once relay capabilities is reported to believe upper The relay capabilities of this terminal change after breath, report relay capabilities information, otherwise, do not report to UE_con.

In the embodiment of the present invention, it is assumed that terminal, which only reports, indicates its relay capabilities information that can be used as relay node, but Its relay capabilities letter that not can be used as adjacent service relay node of instruction is not reported when it not can be used as adjacent service relay node Breath.So, based on the above-mentioned implementation for arbitrarily reporting relay capabilities information, neighbouring terminal is reported to UE_con with UE_con The premise of relay capabilities information is to can be used as adjacent service relay node.

Based on the above-mentioned arbitrarily neighbouring terminal side embodiment of the method with UE_con, UE_ is received with UE_con neighbouring terminal Before the identification information for the terminal that can be used as adjacent service relay node that con is sent, relaying section can also be sent to UE_con Point identification solicited message.

Further, it when sending relay node identification request information to UE_con, can also send to UE_con for spy Determine the relay capabilities solicited message of terminal；And/or the identification information of Correspondent Node is sent to UE_con.

Optionally, relay node identification request information, to the relay capabilities solicited message of particular terminal and Correspondent Node Identification information can carry and be sent to UE_con in the same message.

Correspondingly, if carrying relay capabilities solicited message in a message without carrying the relaying energy to particular terminal The identification information of all terminals that can be used as adjacent service relay node of maintenance can be sent to by power solicited message, UE_con Give the terminal of the message.If carrying relay node identification request information and the relaying energy to particular terminal in the same message Power solicited message, UE_con can send out the identification information of particular terminal in the terminal that can be used as adjacent service relay node of maintenance Give the terminal.

Based on above-mentioned any requesting terminal side embodiment of the method, neighbouring terminal reports relaying energy to UE_con with UE_con When force information, the identification information of adjacent node can also be reported to UE_con.

Optionally, the identification information of relay capabilities information and adjacent node can be carried in the same message.

Below in conjunction with concrete application scene, method provided in an embodiment of the present invention is described in detail.

As shown in fig. 6, the proximity relations between UE_A, UE_B, UE_C, UE_D, UE_E, UE_F, UE_G is connected with solid line It indicates, each terminal can be used as adjacent service relay node.UE_con and each terminal are neighbouring.

The instruction of UE_con periodic broadcast relay capabilities information reporting or center control point identification information.Receive broadcast Each terminal report respective relay capabilities information.

The mark for the terminal that UE_con can be used as adjacent service relay node according to the relay capabilities maintenance of information received is believed Breath.Since UE_con also can be used as adjacent service relay node, the end that can be used as adjacent service relay node of maintenance It further include the identification information of itself in the identification information at end.

When UE_A needs to initiate adjacent communication to UE_B by adjacent service relay node, UE_A is into UE_con transmission After node identification solicited message, UE_A can also request the relaying of its adjacent terminals UE_C, UE_D, UE_E and UE_F to UE_con Ability then sends the relay capabilities solicited message for being directed to particular terminal (UE_C, UE_D, UE_E and UE_F) to UE_con.

If UE_A sends relay node identification request information to UE_con, UE_con obtains all of maintenance and can be used as Identification information (the i.e. mark of UE_B, UE_C, UE_D, UE_E, UE_F, UE_G and UE_con of the terminal of adjacent service relay node Know information) and it is sent to UE_A；If UE_A is sent to UE_con for particular terminal (UE_C, UE_D, UE_E and UE_F) Relay capabilities solicited message, then UE_con obtains the identification information of the particular terminal that can be used as adjacent service relay node of maintenance The identification information of (i.e. the identification information of UE_C, UE_D, UE_E and UE_F) and UE_con are simultaneously sent to UE_A.
