Embodiment
In more detail the preferred embodiment of the present invention is described below with reference to accompanying drawings.Although show the preferred embodiment of the present invention in accompanying drawing, but should be appreciated that, the present invention can be realized in a variety of manners and not should limit by the execution mode of setting forth here.On the contrary, provide these execution modes to be to make the present invention more thorough and complete, and complete for scope of the present invention can be conveyed to those skilled in the art.
Fig. 1 shows the schematic diagram of the network architecture of the LTE system introduced after ProSe service.In FIG, for the land radio access web of evolution (E-UTRAN), current LTE system is described.As shown in fig. 1, mobile management entity (MobilityManagementEntity in E-UTRAN and core net, MME)/gateway (S-GW) is connected, core network part also comprises home subscriber server (HomeSubscriberServer, HSS), Secure User Plane locating platform (SUPLLocationPlatform, SLP) and close to application server (ProSeApplicationServer) etc.In order to support that ProSe serves, introduce ProSe functional entity (ProSeFunction) in a network, as shown in the figure.This ProSe functional entity is connected (only schematically illustrating ProSe functional entity in Fig. 1 to be connected by PC3 interface with wanting the UEA initiating ProSe direct communication) by PC3 interface with one or more UE.In addition, this ProSe functional entity is connected with HSS by PC4a interface, is connected with SLP by PC4b interface.In addition, one or more ProSe application server in this LTE system, can being comprised, applying for providing corresponding ProSe.
Interface between each entity in E-UTRAN shown in Fig. 1 is known in the art, therefore repeats no more here.
ProSe functional entity is to support that in LTE system ProSe serves the logical functional entity introduced, and it is responsible for storing and provide all information needed for ProSe service, performs and serves control of relevant behavior etc. to ProSe.For the different aspect of ProSe service, ProSe functional entity plays the part of different roles.In this article, suppose to only have a ProSe functional entity in each Public Land Mobile Nerwork (PLMN) to support that ProSe serves.But, it will be understood by those skilled in the art that the present invention is not limited thereto, but the situation with any number of ProSe functional entitys can be applied in LTE system.
As previously mentioned, for ProSe direct communication, there is two spike-type cultivars allocation model, namely above-mentioned pattern 1 and pattern 2.
For pattern 1, Resourse Distribute is by asking the serving BS of the UE of ProSe direct communication to dispatch, and therefore it is only applicable to the UE (that is, UE is in the coverage of its serving BS in LTE system) with the network coverage.
And for pattern 2, Resourse Distribute determines by asking the UE of ProSe direct communication, therefore it is not only applicable to the UE with the network coverage, and the UE being applicable to not have the network coverage (namely, now UE does not find suitable persistent district in LTE system, can not carry out with network communicate (namely not having corresponding serving BS to serve it)).
Fig. 2 shows the flow chart for the method 200 of supporting ProSe to serve in LTE system according to one embodiment of the present invention.In method 200, using forestland 1 carries out Resourse Distribute, that is, carry out scheduling resource by serving BS and distribute.
As shown in Figure 2, method 200 comprises step 210, and in step 210, UEA sends ProSe direct communication request to its serving BS eNB, is the Radio Resource that its point is used in ProSe direct communication to ask eNB.
In one implementation, UEA sends dispatch request in step 210 to its serving BS eNB, and the buffer status report relevant to direct communication business (BSR).After UEA connects with serving BS, directly can send the relevant buffer status report of direct communication business to serving BS.Based on the BSR received from UEA, service eNB can determine that UEA has for carrying out the data volume of ProSe direct communication and thus estimating the quantity of the resource of this data volume of transmission.
In step 220, eNB obtains the information of the common process ability be associated with UEA.
In one implementation, the information of the common process ability be associated with UEA is sent to eNB (in as Fig. 2 shown in step 220a) by UEA while sending ProSe direct communication request to eNB or after sending ProSe direct communication request to eNB.Such as, UEA can obtain the information of this common process ability from ProSe functional entity when it obtains the mandate of ProSe functional entity execution ProSe direct communication.
In another implementation, eNB obtains the information (as shown in step 220b Fig. 2) of this common process ability from MME.MME (InitialContextSetupRequest) when sending the context about this UE to eNB have sent the information of described common process ability to this eNB.Other implementation has, and eNB, after receive ProSe direct communication request from UEA, determines whether to allow UEA to perform ProSe direct communication to MME request; Or the common process ability information (such as obtain the authorization, but MME not sending the common process ability information of this UE execution ProSe direct communication to the situation of base station) of carrying out ProSe direct communication is obtained to MME request.When MME determines to allow UEA to perform ProSe direct communication, to eNB return authorization information, in this authorization message, comprise the information of this common process ability; Or MME returns the information of common process ability.
In another realizes, eNB obtains the information (as shown in step 220c Fig. 2) of this common process ability from ProSe functional entity.Such as, eNB after receive ProSe direct communication request from UEA, can ask the information of the common process ability be associated with UEA to ProSe functional entity (as shown in fig. 1) by MME.
In this article, the information of the common process ability be associated with UE (such as UEA) can be determined by least one item in the following:
UEA and carry out the maximum processing capability (situation about transmitting one to one) of other UE (as UEB) of ProSe direct communication with UEA; Or
UEA and with UEA carry out other UE (not shown)s multiple of ProSe direct communication maximum processing capability (i.e. the maximum processing capability of one group of UE, one-to-many transmission situation); Or
The maximum processing capability corresponding to identifier (ProSeApplicationID) of the ProSe application that UEA carries out; Or
The value that operator is pre-configured.
Here, maximum processing capability comprises at least one item in the following:
For each UE carried out in each UE of ProSe direct communication, the maximum number bits of the transmission block (transmission block transmitted on ProSe communicates shared channel) in a Transmission Time Interval (TTI);
For each UE carried out in each UE of ProSe direct communication, the maximum number bits of all transmission blocks (transmission block transmitted on ProSe communicates shared channel) in a Transmission Time Interval (TTI); And/or
Whether each UE carrying out ProSe direct communication supports 64 quadrature amplitude modulation (QAM) modulating mode and/or 256QAM modulating mode.
In addition, maximum processing capability also can be pre-configured by standard, and in this case, base station or UEA direct basis standard predetermined value carry out Resourse Distribute.In other cases, base station or UEA directly or indirectly can obtain maximum processing capability from ProSe functional entity, and use the maximum processing capability obtained to carry out Resourse Distribute.
Here, use maximum processing capability can make in a TTI, to send at transmission UE the transmission block exceeding and receive UE disposal ability, this will cause bust this.Accordingly, receive UE and can not receive the transmission block exceeding its disposal ability in a TTI, guarantee that UE correctly receives the data of direct communication.If certain receives the transmission block that UE receives the multiple ProSe business sent from multiple transmission UE simultaneously, when but total transmission block exceedes its maximum processing capability, receive the transmission block that UE independently determines to receive the ProSe business which or which transmission UE sends, and abandon other transmission block.
Such as, for each UE carrying out ProSe communication, some UE may have higher disposal ability (such as 2Mbps), and other UE have lower disposal ability (such as 1Mbps), the common process ability then finally determined should meet the demand of lower reason ability, such as, be 1Mbps.In addition, ProSe functional entity can know the disposal ability (situation of one-to-many) of each member of the group of carrying out ProSe direct communication, or the disposal ability needed for ProSe application of carrying out corresponding to ProSe direct communication can be known, thus determine and the common process ability of carrying out ProSe direct communication required for UEA and being associated.
Again such as, if 64QAM modulation is supported in the instruction of common process ability, then eNB can distribute less resource (compared to 16QAM) for transfer of data, because 64QAM is higher than the spectrum efficiency of 16QAM.
When common process ability is associated with the identifier that ProSe applies, the distribution of Radio Resource also should consider the involved maximum processing capability needed for specific ProSe application.
In one implementation, with above-mentioned, maximum processing capability pre-configured in a standard can also be determined that the mode of common process ability combines.
Such as, in a standard for ProSe direct communication has pre-defined a maximum processing capability, but the transmission UE (as UEA) of participation ProSe direct communication and reception UE (as UEB) have higher disposal ability, then ProSe functional entity can be this transmission UE and receive the higher common process ability of UE dynamic-configuration, and providing it to service eNB, the higher common process ability of now base station needs employing distributes the Radio Resource needed for direct communication.
Next, in step 230, distributed Radio Resource, according to the information of this common process ability, for UEA divides the Radio Resource being used in and carrying out ProSe direct communication, and in step 240, is informed to UEA by eNB.
Here, due to the restriction of common process ability, eNB can not distribute more Radio Resource (as Physical Resource Block (PRB)) to transmit the data more than 1Mbps for UEA.Here, also suppose that dispatching distribution (SchedulingAssignment) is no more than this common process ability.
After this, UEA can utilize distributed Radio Resource and other UE one or more to carry out ProSe direct communication.In Release12, ProSe direct communication refers to that UEA transmits data to other UE, and other UE do not need to send feedback information.In evolution afterwards, when UEA transmits data to other UE, other UE may need to send feedback information.
Below, RRC connection establishment process that wireless heterogeneous networks (RRC) connects is set up to describe one of the embodiment shown in Fig. 2 way of realization more specifically in conjunction with UE and eNB.Fig. 3 shows the flow chart of a kind of implementation method more specifically 300 of the method shown in Fig. 2.
As shown in Figure 3, when being in the UE (as UEA) in the Serving cell coverage that service eNB controls and wanting to perform ProSe direct communication in Serving cell, system information should be ProSe direct communication to its instruction UEA and sets up RRC connection (concrete indicating mode is existing disclosed scheme, and the present invention does not launch to describe).For this reason, in step 310, UEA and service eNB are set up RRC and are connected.Establish after RRC is connected in UEA and service eNB, in step 320, service eNB sends the initial UE message be associated with UEA to MME; In step 330, MME sends initial context to service eNB and sets up request message; In step 340, service eNB returns initial context to MME and sets up response message.
Here, step 310-340 is substantially the same with conventional RRC connection establishment process, therefore repeats no more.
In one implementation, UEA sends ProSe direct communication request to service eNB in the step 310.More specifically, this ProSe direct communication request can send to service eNB by RRC connection setup complete message by UEA in the RRC process of establishing of step 310.Or, UEA can establishing after RRC is connected (layer 3) with service eNB, by layer 2MAC (Medium Access Layer) signaling to service eNB send dispatch request and/or the BSR relevant to direct communication business with to service eNB request for carrying out the Radio Resource of ProSe direct communication.
In this case, in step 330, MME sets up in request message at the initial context sent to service eNB and the information of the common process ability be associated with UEA is sent to service eNB.
In another implementation, UEA can send ProSe direct communication request by independent specific messages to service eNB.Such as, UEA can send UE supplementary for requests resource allocation to carry out ProSe direct communication by independent step (step 350 as in Fig. 3) to service eNB.
In this case, service eNB can receive the information (not shown) of the rear common process ability be associated with UEA to the request of MME or ProSe functional entity of ProSe direct communication request of UEA.Or in this realization, the information of the common process ability be associated with UEA also still can be sent to the service eNB of UEA in a step 330 by MME.In other words, service eNB can obtain the information of the common process ability be associated with UEA in advance from MME or ProSe functional entity, and no matter whether it have received ProSe direct communication request from UEA.
In step 360, service eNB is that UEA distributing radio resource is for carrying out ProSe direct communication according to the information of the common process ability be associated with UEA.
After service eNB is assigned with Radio Resource, service eNB can be initiated RRC and connect reconfiguration course, so that distributed Radio Resource is informed to UEA.Or serving BS is controlled by physical layer, and letter is modern informs to UEA (not shown) by distributed Radio Resource.
Specifically, in step 370, service eNB sends RRC to UEA and connects reconfiguration message, comprising the information of the distributed Radio Resource for ProSe direct communication.
In step 380, UEA returns RRC connection to service eNB and has reshuffled message, has reshuffled to connect to service eNB notice RRC.
As 4 show the flow chart for the method 400 of supporting ProSe to serve in LTE system according to another embodiment of the present invention.In method 400, using forestland 2 carries out Resourse Distribute, that is, carry out the UE (as UEA) self of ProSe direct communication to carry out resource selection by hope.
As shown in Figure 4, in step 410, the UEA iting is desirable to carry out ProSe direct communication obtains the information of common process ability associated with it from ProSe functional entity.
Next, in step 420, UEA, according to the information of this common process ability, selects Radio Resource for carrying out ProSe direct communication from resource pool.
In method 400, UEA can have serving BS and (such as have RRC be connected with serving BS or be residently in idle condition in the cell, namely, have the situation of the network coverage) or not there is the Serving cell that serving BS controls coverage within (that is, without the situation of the network coverage).
