Description
Technical field
The present invention relates to communication technical field, relate in particular to the method, system and device of a kind of transmission enhanced multimedia broadcast multicast service (EMBMS, Enhanced Multimedia Broadcast Multicast Service).
Background technology
Long Term Evolution (LTE, Long Term Evolvement) standard be 3GPP organize to set up based on universal terrestrial access network (UTRAN, Universal Terrestrial Radio Access Network) evolution standard, its EMBMS that provides can support the multi-medium data transmission and the better service quality of higher rate, its architecture as shown in Figure 1, SGmb interface of describing among Fig. 1 and SGi-mb interface are enhancement mode broadcast/multi broadcast business control (eBM-SC, enhanced Broadcast/Multicast ServiceControl) node and core net multimedia broadcast multi-broadcasting business (MBMS, Multimedia BroadcastMulticast Service) interface between the node M BMS2, wherein, the SGmb interface provides the control plane function, and the SGi-mb interface provides user-plane function.EBM-SC is the inlet of MBMS service supplier, is used for authorizing and initiating business, and preserves some business parameters datas, and send professional to schedule.Towards the Access Network side, the MBMS2 service surface node is that the EUTRAN node (is evolved base station (ENB by the M1 interface, Enhanced Node B)) provide user terminal (UE) required EMBMS data, and chain of command node M BMS1 provide professional relevant chain of command information by the M3 interface for ENB.
In EUTRAN, in order further to promote the transmission characteristic of the one-to-many (PTM) of EMBMS, promote the service efficiency of air interface resource as much as possible, LTE has introduced Multicast Broadcast Single Frequency Network (MBSFN in Access Network, Multicast/Broadcast Single Frequency Network) this has the network of new transmission characteristic, MBSFN is used to strengthen the downlink transfer processing gain of EMBMS, promptly support the descending grand diversity of (inter-cell) edge, the throughput of elevator system and user's experience between the sub-district in the MBSFN territory.
Referring to Fig. 2,, provided following description in the 3GPP TS36.300 agreement about the correlation technique characteristic of MBSFN:
MBSFN retaining zone (MBSFN Synchronization Area): promptly its inner ENB all can obtain synchronously and the zone of carrying out the MBSFN transmission.The MBSFN retaining zone can be supported one or more MBSFN zone.At the specified frequency layer, an ENB only belongs to a MBSFN retaining zone.The definition of MBSFN retaining zone is independent of the definition in EMBMS zone.
MBSFN transmits (MBSFN Transmission): promptly a kind of radio hookup transmission technology, realize by transmitting identical signal waveform simultaneously in a plurality of sub-districts.The MBSFN of a plurality of sub-districts transmission can be regarded as single transmission from one " big sub-district " by a UE in the MBSFN zone.
MBSFN zone (MBSFN Area): one group of sub-district that the MBSFN retaining zone is interior in the MBSFN area containing network.Sub-district in the MBSFN retaining zone can constitute a plurality of MBSFN zone, and each MBSFN zone is to distinguish with participation the different of set of cells according to the transmission content of its carrying.
Transmission/announcement sub-district in the MBSFN zone (MBSFN Area Transmitting and AdvertisingCell): be called for short TAC, be the class sub-district in the MBSFN zone, this sub-district had both participated in MBSFN and had sent the announcement that also participates in MBSFN transmission availability in the sub-district.
MBSFN zone sends sub-district (MBSFN Area Transmitting-Only Cell): being called for short TOC, is the class sub-district in the MBSFN zone, and this sub-district only participates in MBSFN and sends and do not participate in the announcement that the MBSFN sub-district in transmits availability.The use of this type of sub-district remains further to be studied.
Keep sub-district (MBSFN Area Reserved Cell) in the MBSFN zone: be called for short the Reserved sub-district, it is a sub-district in the MBSFN zone, this sub-district does not participate in MBSFN and sends, this sub-district can allow to transmit other business, but must limit the transmitted power of corresponding service on the Radio Resource that configuration is transmitted to MBSFN.
In addition, support the sub-district of EMBMS on carrier capability, to have following two kinds of divisions:
MBMS dedicated cell (EMBMS-dedicated Cell): the sub-district that the MBMS business support only is provided.
MBMS/Unicast mixed cell (EMBMS/Unicast-mixed Cell): not only supported the MBMS service point to multicast communication but also support the sub-district of the professional point-to-point transmission of clean culture (Unicast).The also corresponding MBMS/Unicast mixed carrier (or shared carrier wave) that is called of the residing carrier wave in this sub-district.
Because at the improvement of related physical layer and transport layer, network layer has had brand-new characteristic and demand naturally in the LTE system.Under the scene of disposing Single Frequency Network (MBSFN), sub-district in the MBSFN territory is that strict synchronism (comprises that node is synchronous, content synchronization, and air interface is synchronous), therefore the UE at the cell boarder place can obtain downstream signal energy merging gain effectively, this gain is equivalent to enable in the dedicated link high speed downlink packet substantially and inserts the gain that (HSDPA) technology is obtained, and because " synchronously " characteristic of minizone in the MBSFN territory, interference between the EMBMS bearing resource is obviously to reduce, thereby the EMBMS signal quality of minizone boundary is highly improved in the MBSFN territory.
Referring to Fig. 3; when the UE that is in free time (Idle) state outwards crosses over the MBSFN border from the MBSFN zone; UE need experience the transition to MBSFN border cell (boundary belt) by TAC; because the MBSFN border cell can be made up of TOC and Reserved sub-district; and there is corresponding restriction in the EMBMS that UE is receiving on boundary belt; be to be not send EMBMS on the Reserved sub-district, and TOC send EMBMS and the control corresponding surface information is not provided with limited power.
For being in the UE in the MBSFN boundary strip of forming in TOC or Reserved sub-district, might be on the hazard to the normal reception of EMBMS.This is because the MBMS Traffic Channel (MTCH of the sub-district in the MBSFN boundary strip, MBMS Traffic Channel) be not launch or power limited ground emission EMBMS, to such an extent as to the service signal of MBSFN pattern merges gain and occurs descending, and might cause normally demodulation EMBMS information of UE.Further, in case UE advances to MBSFN is overseas, will enter MBSFN and cover outer sub-district, this type of sub-district does not provide the emission of EMBMS.At this moment, the Idle attitude UE that receives EMBMS just must receive for the continuation (normally) that realizes EMBMS, and to network request of sending or indication, so that network is set up the transmission resource (comprising transfer resource and Radio Resource) of corresponding EMBMS in UE present located sub-district,, the Idle attitude UE that enters this sub-district supports for providing EMBMS.
Yet, only illustrated for the Idle attitude UE that receives EMBMS in the existing TS36.300 standard and implemented cell reselection process, successional correlative detail for the EMBMS reception, as: the characteristic information that receives EMBMS, UE walks out transport-type conversion that may cause in the MBSFN territory etc., does not all provide clear and definite technical scheme.
In sum, do not provide the technical scheme that realizes receiving continuously EMBMS when the Idle attitude UE that receives EMBMS passes through the MBSFN border in the prior art, be that prior art can't guarantee that Idle attitude UE can receive EMBMS continuously, thereby cause the quality of reception of EMBMS relatively poor.

Embodiment
The embodiment of the invention provides a kind of method, system and device of transmitting EMBMS, the user terminal that is applied to be in idle condition utilizes the resource of many sub-districts point-to-multipoint pattern to receive in the process of EMBMS in Multicast Broadcast Single Frequency Network, in order to improve the quality of reception of EMBMS.
Based on the MBSFN region characteristic---many cell energies of MBSFN merge the characteristic of characteristic and MBSFN territory border cell type (TOC or Reserved sub-district), can find, UE when the Idle attitude that receives EMBMS, from the central area (TAC overlay area) in MBSFN zone shown in Figure 3 to the process that move the outside, might enter into the common sub-district that EMBMS is not provided, this is a basic scene on the EMBMS/Unicast mixed carrier (or claiming to share carrier wave).
Under shared carrier wave scene, for the continuity demand when outwards passing through the MBSFN border for the UE that receives EMBMS, conversion EMBMS emission mode a kind of simple and effective scheme of can yet be regarded as, for example: by many sub-districts point-to-multipoint (MC-PTM, Multi-Cell Point To Multi-point) mode switch is that single cell point is to multiple spot (SC-PTM, Single-Cell Point To Multi-point) pattern, so just can avoid adopting in the MBSFN territory the shared resource of MC-PTM pattern, use the resource of the SC-PTM pattern of new configuration to provide corresponding EMBMS at Target cell for the UE that moves to this sub-district, realize the continuous reception of EMBMS, improve the EMBMS quality of reception of UE.
The technical scheme that provides in the embodiment of the invention, all be based on the technical scheme of EMBMS emission mode conversion, promptly based on of the conversion of PC-PTM pattern to the SC-PTM pattern, use with the MBSFN zone in the shared different resource (transmission resources of SC-PTM pattern) of Radio Resource (transmission resources of PC-PTM pattern) during transmission EMBMS, realize the quadrature of resource, suppressed presence of intercell interference, and then utilize the controlling links technology (as: Adaptive Modulation and Coding (AMC of SC-PTM, Adaptive Modulationand Coding) technology) guarantee the receptivity of EMBMS data, and professional continuity.
Referring to Fig. 4, the method for a kind of transmitting EMBMS that the embodiment of the invention provides totally comprises step:
S401, utilize the resource of the PC-PTM pattern that ENB distributes to receive in the process of EMBMS at UE, UE sends the EMBMS request message to ENB, ENB is the resource that emission EMBMS sets up the SC-PTM pattern according to this EMBMS request message, and described configuration information of resource is notified to described UE.
S402, ENB adopt single cell point to the multiple spot pattern, launch EMBMS by the resource of newly-built SC-PTM pattern to described UE.
S403, UE are known the resource of ENB for the newly-built SC-PTM pattern of emission EMBMS according to the configuration information of resource of SC-PTM pattern, and receive the EMBMS of described ENB emission by the resource of newly-built SC-PTM pattern.
The embodiment of the invention is the SC-PTM pattern by the MC-PTM mode switch, adopt the resource emission EMBMS of newly-built SC-PTM pattern can avoid the resource that the MC-PTM pattern is used in the MBSFN territory, use the SC-PTM transmission resources of new configuration to provide corresponding EMBMS at Target cell, realize the continuous reception of EMBMS for mobile UE.This shows that the MC-PTM pattern is a key point to the triggering mode of SC-PTM mode switch and triggering opportunity, at this key technology, the embodiment of the invention provides following concrete technical scheme.
At first, the trigger mechanism that the autonomous pattern formula of UE that providing the embodiment of the invention provides is changed specifically comprises two kinds of schemes of following option A and option b.
Option A, based on the triggering of MBSFN universe:
For the initial stage of arranging net, the MTCH quality of reception of UE might be not high among the TAC, can produce the situation that EMBMS that UE receives can not satisfy the demands, for example: for the frequency selective fading scene.Therefore, not only need carry out of the conversion of MC-PTM pattern in this case to the SC-PTM pattern at the MBSFN boundary, so present embodiment is not limited to the MBSFN border cell, the EMBMS quality of reception drops to the sub-district (no matter being TAC, TOC or Reserved sub-district) of default thresholding all by the EMBMS quality of reception to measure of UE based on self in the MBSFN territory, initiatively start the conversion of EMBMS sending mode, detailed process comprises:
Step 1: UE measures and adjudicates for the EMBMS quality of reception (as: using the interpolation pilot tone of Traffic Channel), if measured value is lower than the setting thresholding, then UE just initiates the request of access network, i.e. wireless resource control connection request (RRC Connection Request) in current area.
Step 2: UE resends EMBMS request (EMBMS Service Request) by Radio Resource control (RRC, the Radio Resource Control) connection of setting up to the ENB of network side subsequently.
The information that comprises among the EMBMS Service Request has: the UE EMBMS quality of reception at this moment descends, and the request network side is the resource of the newly-built SC-PTM pattern of emission EMBMS, and finishes the conversion of MC-PTM pattern to the SC-PTM pattern.
Step 3: after the ENB of network side receives the EMBMS Service Request message of UE transmission, set up the resource (comprising transfer resource and Radio Resource) of corresponding SC-PTM pattern immediately for the EMBMS of UE request, and by dedicated signaling or Cell Broadcast CB the configuration information of resource of newly-built SC-PTM pattern is announced to UE, the ENB of network side adds the corresponding EMBMS multicast of the EMBMS group with the UE request simultaneously.
At this moment, UE just can continue to receive the EMBMS of ENB with the emission of SC-PTM pattern on the resource of new configuration.
Option b, based on the triggering on border, MBSFN territory:
For the network of maturation, the operation that its MBSFN territory lives through certain hour is forged, and network configuration is optimized, and the MBSFN of EMBMS data merges the assurance that performance has had the radio layer configuration of optimizing, in the TAC of inside, MBSFN territory, the EMBMS quality of reception of UE is stable.At this moment, the EMBMS quality of reception that UE is all carried out in all kinds of sub-districts on MBSFN has just been measured not necessarily.And long-time too frequent measurement is unfavorable for the electric power saving of UE, need overcome.
Therefore, preferably, be comparatively rational when the EMBMS quality of reception measuring process of UE is limited in UE and is about to walk out the MBSFN zone.Concrete scheme comprises: be the border topology information in UE indication MBSFN territory by network side, for example, (promptly indicating UE present located sub-district is TAC can to indicate the MBSFN type information of this sub-district in the system broadcast information of sub-district, TOC still is the Reserved sub-district), after being convenient to UE and entering the MBSFN border, open the measurement of the EMBMS quality of reception targetedly, when the MC-PTM pattern when the switch condition (being that the EMBMS quality of reception is lower than default thresholding) of SC-PTM pattern is set up, UE sends the EMBMS Service Request message identical with the described EMBMS Service of option A Request message to ENB, so that network side carries out the conversion of corresponding M C-PTM pattern to the SC-PTM pattern for it, in order to launch EMBMS, dispose the resource of new SC-PTM pattern, thereby serve for the continuation of the UE of Idle attitude receives EMBMS, guarantee the reception continuity of EMBMS.
To sum up, the common feature of option A and option b comprises:
1, UE sends EMBMS Service Request message to network, depends on the measurement result of the EMBMS quality of reception that UE grasps.
2, network is follow-up is directly carried out to the triggering of SC-PTM mode switch by the MC-PTM pattern, need UE to initiate not have other condition outside the EMBMS Service Request message.
Provide the trigger mechanism of the MBSFN border indicator type mode switch that the embodiment of the invention provides below.
The trigger mechanism that the autonomous pattern formula of UE that being different from the embodiment of the invention provides is changed, the core methed of MBSFN border indicator type mode switch trigger mechanism comprises:
Step 1, network side are the border topology information in UE indication MBSFN territory, as: indicate the MBSFN type information of MBSFN territory border cell in the system broadcast information of sub-district, promptly this sub-district is the information of TAC, TOC or Reserved sub-district.
Step 2, UE are initiated the request (RRC Connection Request) of access network detecting when oneself having entered the MBSFN border cell in current area.
Step 3, UE connect the message to network side initiation EMBMS Service Request by RRC.
After the ENB of step 4, network side received EMBMS Service Request message from UE, based on the different designs target, ENB can carry out following scheme C or scheme D:
Scheme C, ENB carry out the conversion of MC-PTM pattern to the SC-PTM pattern immediately:
When ENB receives the EMBMS Service Request message of UE, the continuity of determining UE reception EMBMS is about to be on the hazard, as: when the border in MBSFN zone is configured to one deck Reserved type border cell, owing to do not launch the EMBMS data in the Reserved sub-district, thereby the quality of reception of EMBMS descends in the Reserved sub-district obviously, and after UE enters the border cell of MBSFN, very likely entering does not fast provide the Unicast of corresponding EMBMS the sub-district, for the UE that the fair speed straight line moves, this tendency is more outstanding.
At this moment, ENB is the SC-PTM pattern with the emission mode of EMBMS from the MC-PTM mode switch immediately, and is the resource of the new SC-PTM pattern of this UE configuration, to continue providing UE required EMBMS, guarantees the reception continuity of EMBMS at the MBSFN boundary.
The characteristics of this scheme C are: UE sends EMBMS Service Request message to network side after entering into the MBSFN border cell and detecting the border cell type indication of network side transmission immediately; And after network side receives the EMBMS Service Request message that UE sends, implement the conversion of MC-PTM pattern to the SC-PTM pattern immediately, and dispose the emission that new resource is used for EMBMS under the SC-PTM pattern.Simultaneously, ENB is by cell system broadcasting or use dedicated signaling with the notice of the configuration information of resource under new SC-PTM pattern UE, so that UE continues to receive EMBMS from new resource.
Scheme D, ENB carry out the conversion of MC-PTM pattern to the SC-PTM pattern based on self making a strategic decision:
C is different with scheme, if the border of MBSFN is multiple (multilayer), and the type of border cell is TOC, and then the signal intensity attenuation of EMBMS is comparatively slowly, can provide corresponding EMBMS to continue as the UE that enters completely.At this moment, based on the request of UE and the MC-PTM pattern of carrying out just needn't start immediately to the transfer process of SC-PTM pattern.
In border cell, under the enough good premise of EMBMS signal quality, implement of the conversion of MC-PTM pattern immediately to the SC-PTM pattern, the signal that can waste the MBSFN pattern merges gain, and can take new resource (comprising transfer resource and Radio Resource) prematurely, reduced the service efficiency of air interface.Thereby, can consider that after network side is received the EMBMS Service Request message of UE start the measurement control at UE, indication UE carries out predefined measurement, promptly notify UE to measure the current EMBMS quality of reception, and receive the measurement feedback of the EMBMS quality of reception of UE.Think that up to ENB the EMBMS quality of reception of UE has dropped under the assurance thresholding of setting, ENB just starts the transfer process that arrives the SC-PTM pattern at the MC-PTM pattern of UE, and disposes the emission that new resource is used for EMBMS under the SC-PTM pattern.Simultaneously, ENB is by cell system broadcasting or use dedicated signaling with new resources configuration information notice UE, so that UE continues to receive EMBMS from new resources.
The trigger mechanism of scheme C and scheme D has a common feature that is different from option A and option b:
UE sends the border discovery result that EMBMS Service Request message only is based on MBSFN to network side; The follow-up MC-PTM pattern of carrying out of network side is based on the decision-making of ENB opportunity to the triggering of SC-PTM mode switch.
Introduce the standard of the EMBMS quality of reception deterioration of judging UE in the embodiment of the invention below, promptly need to carry out the condition of MC-PTM pattern to the SC-PTM mode switch.
As shown in Figure 5, in view of TOC only provides the transmission of EMBMS, and do not provide the transmission of phase related control information.Thereby from the receiving angle of UE, because the corresponding control information of the Traffic Channel of EMBMS need receive from the TAC that closes on, so for the Traffic Channel of EMBMS, the quality of reception of the control channel of EMBMS is along with outer the moving of UE more significantly descends appearance.
Since the quality of EMBMS control channel descend move with UE outer more obvious, therefore for the estimation of the EMBMS quality of reception of UE can not be only based on the Traffic Channel of EMBMS, that is to say, under the situation that satisfies EMBMS received energy index request, the quality of reception of EMBMS control channel has dropped to disabled state, in case at this moment new scheduling has taken place in the Traffic Channel of EMBMS, then owing to lack the indication of control information, UE will can't receive EMBMS suddenly, and this continuity for EMBMS has very bad influence.
Therefore, the embodiment of the invention proposes the judgement of the EMBMS quality of reception of UE should be based on the measurement of the combination property of the Traffic Channel of EMBMS and control corresponding channel, as long as one of them is lower than the setting thresholding, can think that the EMBMS quality of reception of UE worsens, the mode switch that reaches setting triggers opportunity, should carry out the conversion of MC-PTM pattern to the SC-PTM pattern.
