Embodiment
To describe exemplary embodiment of the present invention hereinafter in conjunction with the accompanying drawings in detail.Hereinafter, omitted description for simplicity's sake for well-known function or structure.
Fig. 1 has illustrated the configuration of MBMS mobile communication system.Especially, show Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, UMTS) terrestrial radio access network (Universal Mobile Telecommunications System Terrestrial Radio AccessNetwork, UTRAN), (3rdGeneration Project Partnership 3GPP) realizes MBMS to its third generation project cooperation scheme at asynchronous third generation communication standard in the system.
With reference to figure 1, UE the 161,162,163,171, the 172nd, and MBMS enables the terminal equipment or the MBMS subscriber of (MBMS-enabled).First and second sub-districts 160 and 170 (sub-district 1 and sub-district 2) are Node B control, wireless transmission MBMS data geography or the logic region to the subscriber by base station equipment.Radio network controller (Radio Network Controller, RNC) 140 control sub-districts 160 and 170, optionally transmit multi-medium data to specific sub-district, be controlled to be MBMS service and the radio channel of foundation.Be called as radio resource control (Radio Resource Control, RRC) interface being connected between RNC 140 and the UE 161 to 172.
By Serving GPRS Support Node (Serving GPRS Support Node, SGSN) 130, RNC140 is connected to grouping and switches (PS) network internet for example of (Pachet Switched) or packet service (Packet Service).Communicate between RNC140 and PS network by PS signal (signaling).Especially, the connection between RNC 140 and SGSN 130 is called as an Iu-PS interface.
SGSN 130 controls are used for individual subscriber's the service that is associated with MBMS.These services comprise the service bill data of managing each subscriber and optionally transmit multi-medium data to specific RNC 140.
The transfer network (transit network, NW) 120 be provided at the broadcast multicast services center (BroadcastMulticast Service Center, BM-SC) 110 and SGSN130 between communication path.Transfer NW120 can pass through Gateway GPRS Support Node (Gateway GPRS Support Node, GGSN: not shown) and be connected to external network.BM-SC 110 be responsible for the MBMS data dispatch the MBMS data source.To be sent to UE 161 to 172 from the MBMS data flow that BM-SC110 produces by transfer NW 120, SGSN 130, RNC 140, sub-district 160 and 170.
With reference to figure 2, existing have the exemplary configuration of the MBMS service area of crossover sub-district with description.With reference to figure 2, in the MBMS service area A that specific MBMS service is provided, spatially overlapped by the zone of different frequency f1 and f2 covering.The frequency f 1 or the f2 of crossover, or the sub-district with f1 or f2 is called as frequency layer.
FLC is a following proposal, wherein the UTRAN request UE that has been scheduled to the MBMS service preferably reselects the frequency layer that will transmit the MBMS service thereon, so that given MBMS service is provided on all frequency layer f1 on each frequency layer f1 or the f2 rather than in regional A and f2.In cell configuration shown in Figure 2, if being used for the PL of MBMS service B is f2, then when the MBMS session that is used for MBMS service B begins and in the process of MBMS service B, B just switches to f2 if the UE on the frequency layer f1 among the A of zone wishes to receive the MBMS service, promptly carries out the sub-district and reselects.When the MBMS session begins and in the process of MBMS session, UTRAN instructs the UE on the f1 to move to f2.F2 is the PL of MBMS service B, and f1 be MBMS service B not preferred layer (non-preferred layer, NPL).
B is always not obtainable on NPL in the MBMS service.Signal strength measurement at PL is not enough to be used for can MBMS be served B by RRM and offer them on NPL under the situation of the UE on the NPL.Compare with NPL, specific MBMS service mainly or only is provided on PL.Though for MBMS service B PL is fixed as f2 in above-mentioned example, the PL that is used for MBMS service B may be inequality in zones of different.For example, f2 is the PL that is used for MBMS service B in some zone, and fl is the PL that is used for MBMS service B in another zone.The PL that is used for the MBMS service depends on the operator's of system the sub-district framework strategy and the radio resource status of current area.According to the 3GPP standard, the session of serving from each MBMS begins up to conversation end, and the FLC that concerns between application definition MBMS service and their PL handles.
For an idle pulley UE who joins the MBMS service, there is not the connection of UTRAN and do not have data to transmit.Therefore, it can move to PL from NPL and not consider the availability (availability) of radio resource.On the other hand, the transfer of the UE of connection mode from NPL to PL is subjected to the influence of radio resource availability, this is because it is placed in cell forward access channel (Cell ForwardAccess Channel, CELL_FACH), cell paging channel (Cell Paging Channel, CELL_PCH), UMTS registration area paging channel (UMTS Registration Area PagingChannel, URA_PCH), and cell private channel (Cell Dedicated Channel, CELL_DCH) in the state.
DPCH is not distributed to UE, and UE monitors Common transport channel under the CELL_FACH state.In the CELL_PCH state, UE neither has DPCH and does not also have dedicated logical channel.The URA_PCH state is similar to the CELL_PCH state.At the high mobility of UE cell update is forced under the situation of constraint the URA_PCH state is set.DPCH is available to the UE in the CELL_DCH state.
In the MBMS mobile communication system, according to the radio resource status of corresponding PL, it still is the UE that restriction FLC is used for connection mode that UTRAN can determine FLC is applied to.UTRAN makes by RRM and determines and will determine that the result is sent to the UE in the sub-district that is under the control.The UE of connection mode operates according to the result who determines.FLC scheme according to embodiments of the invention is effective especially for the UE that is under CELL_FACH or the CELL_DCH state.
With reference to Fig. 3 to being used to determine that it still is that the restriction FLC RNC operation that is applied to UE is described in detail that FLC is applied to UE.
To be explanation be used to determine FLC is applied to or limit the flow chart of signal flow of operation that FLC is used for the subscriber equipment of connection mode according to embodiments of the invention Fig. 3.
With reference to figure 3, in step 201, the radio resource that the RNC measurement is used for the PL of ongoing MBMS service limits the UE that FLC is used for connection mode to determine application FLC to the UE of connection mode.
In step 203, RNC determines whether the radio resource through measuring is enough to supply the business that is associated of the UE of connection mode.Should determine can be by considering the availability of PL radio resource, and the number that joins the sum of the connection mode UE on the NPL of MBMS service or be in the connection mode UE under each state of CELL_FACH, CELL_PCH, URA_PCH, CELL_DCH is determined.If radio resource is enough to provide the business that is associated, then the RNC decision is used FLC to the connection mode UE on NPL, and advances to step 205.
In step 205, RNC is provided with FLC applicability information, and FLC_DI (FLC that is used for connection mode UE forbids indication) sends the UE of the connection mode that is associated with the MBMS service to for ' N ' and with it.Here, ' N ' expression FLC is suitable for.In this case, UTRAN can provide non-MBMS service (non-MBMS service) on the PL of MBMS.
Perhaps, if radio resource is not enough to supply the business that is associated, then the RNC decision is not used FLC to connection mode UE, and forwards step 207 to.In step 207, RNC is provided with FLC_DI and is ' Y ', and sends it to connection mode UE.' Y ' expression FLC restriction (restriction).In this case, the supply of the dedicated service service except the MBMS service all is restricted on PL.In other words, UTRAN does not provide any non-MBMS service on the PL of MBMS.Therefore, the FLC_DI value is set to ' Y ' and is known as PL service restricted information.
The FLC_DI value can be the mark of one one bit, and indication FLC is applied to or limits FLC and is used for connection mode UE or the UE under specific RRC state (for example CELL_FACH).Can further consider as an alternative embodiment of the invention, the FLC_DI value is made as one 4 bit map (bitmap) or 2 bit integer, be used for representing for the nearly FLC application or the FLC restriction of four other connection mode states of branch of network.
Under the situation of 4 bit map, first is to FLC application or the FLC restriction of the 4th bit-order ground expression for URA_PCH, CELL_CH, CELL_FACH, CELL_DCH state.For example, ' 0011 ' bitmap can indicate FLC to be limited to be used for UE under CELL_FACH and the CELL_DCH state, but is applied to the UE under URA_PCH and the CELL_PCH state.
Under the situation of 2 bit integer, for example, 2 bit integer 00,01,10 and 11 can represent respectively that FLC is limited to be used for the UE under CELL_DCH, CELL_FACH, CELL_PCH, the URA_PCH state.For example, if integer is ' 01 ', FLC then is limited to be used for the UE under the CELL_FACH state, but is applied to the UE under CELL_DCH, URA_PCH, the CELL_PCH state.
Fig. 4 is that explanation is used to receive FLC applicability information according to embodiments of the invention, is set to the flow chart of operation of connection mode UE of FLC_DI of the mark of a bit.
With reference to figure 4, in step 222, UE receives the FLC notification message that comprises the MBMS preferred frequency information by common signaling (common signaling) or dedicated signaling (dedicated signaling).Preferred frequency information, MBMS side-play amount, FLC_DI that the MBMS preferred frequency information preferably includes for the PL of the service identifier (ID) of MBMS service, indication MBMS service are provided with, and wherein, will carry out FLC to described MBMS service.
In step 224, UE determines the MBMS the service whether service ID that receives indicates this UE to add.If service ID is not equal to the ID of the MBMS that added service, then UE keeps current sub-district in step 234, promptly current frequency and do not carry out this FLC.
If the MBMS service that the service ID indication is added, then UE checks FLC_DI in step 226.If FLC_DI is set to indicate FLC to be limited to be used for UE ' Y ', then UE forwards step 234 to, and UE remains on current frequency and the intensity of not measuring the PL signal does not reselect to PL yet in this step.Even current frequency is NPL, when current frequency has sufficient available resources, interested MBMS service can be provided on the NPL.UE is by learning the availability of the service on the NPL in the MBMS control information that receives on the NPL.
If FLC_DI is set in step 226 ' N ', then UE determines whether current frequency is NPL in step 228.If UE is current on NPL, then the sub-district that it is carried out on the PL in step 230 is reselected.On the contrary, if UE not on NPL, then it keeps current frequency in step 234.
Based on the signal strength measurement of the indicated PL of the FLC notification message that receives in step 222, the sub-district of execution in step 230 is reselected.The MBMS side-play amount is used as the sub-district that increases PL and reselects the factor of probability (factor).
Although in the above-described embodiments, the flag F LC_DI of one bit is provided with that indication FLC is applied to or FLC is limited to be used for connection mode UE or is in UE under the specific RRC state, but if for the applicability of the state of each connection mode indication FLC, then the mark of this bit can be with the integer replacement of 4 bit map or 2 bits.
Fig. 5 illustrates the flow chart that is used to according to another embodiment of the present invention to receive as the connection mode UE operation of the FLC applicability information of a bit labeling.In operation, UE only when its just check on NpL the time FLC_DI value of setting and, if FLC_DI is set to ' Y ', then it carries out service selection process according to priority.
With reference to figure 5, UE receives the FLC notification message that comprises the MBMS preferred frequency information by common signaling or dedicated signaling in step 302.The MBMS preferred frequency information preferably includes the service ID of serving for its MBMS that will carry out FLC, preferred frequency information, MBMS side-play amount, the FLC_DI that indicates the PL of MBMS service.In step 303, UE determines the MBMS the service whether service ID that receives indicates UE to join.If service ID is not equal to the ID of the MBMS service that joins, then UE keeps current sub-district in step 311, that is, and and current frequency, and do not carry out FLC.
If the MBMS service that the service ID indication is added, then UE determines whether current frequency is NPL in step 312.If UE is not on NPL, then it keeps current frequency in step 311.If on NPL, then it forwards step 321 to UE at present.
In step 321, UE checks FLC_DI.If FLC_DI is set to ' Y ', then UE selects ongoing dedicated service service and notifies in the indicated MBMS service one by FLC in step 323.By (UE selects the service with higher priority for Non-Access Stratum, reciprocation NAS) with user or Non-Access Stratum.
In step 324, UE determines whether the service of selecting is by the indicated MBMS service of FLC notification message, promptly has the MBMS service of this PL.If selected the MBMS service, then UE will stop the dedicated service service and proceed to step 322 in step 325.In step 322, the UE measurement is used for the signal strength signal intensity of the PL of MBMS service, and reselects to PL based on this signal strength signal intensity.
If selected the dedicated service service, then UE will continue this dedicated service service and not have FLC to use on current frequency in step 311.
Although in the above-described embodiments, the flag F LC_DI of one bit is provided with that indication FLC is applied to or FLC is limited to be used for the UE of connection mode or is in UE under the specific RRC state, but if for the applicability of the state of each connection mode indication FLC, then the mark of this bit can be replaced with the integer of 4 bit map or 2 bits.
Fig. 6 is explanation is used to transmit and receive the signal flow of MBMS preferred frequency information according to embodiments of the invention figure.In Fig. 6, label 408 one of expression are used for the NPL of specific MBMS service, and label 409 expressions are used for the PL of MBMS service.The coverage of NPL and PL (coverage area) has crossover on the MBMS coverage.Label 410 expression is used to manage the RNC of the radio resource of the NPL that is used for the MBMS service and PL.
With reference to figure 6, RNC 410 receives session (Session Start) message of a session of serving for MBMS from the SGSN of core network in step 411.Session begins message, and session begins the foundation of requirement radio bearer (bearer) for MBMS.Comprising service ID and service quality (QualityofService, QoS) information.
Begin message based on receiving session, RNC410 transmits the FLC notification message as the signaling for FLC in step 421.The FLC notification message preferably includes the service ID of MBMS service, the preferred frequency information of indicating the PL of MBMS service, MBMS side-play amount, FLC_DI setting.The MBMS side-play amount is a threshold value of comparing with the signal strength measurement of PL when the UE on NPL reselects to PL.FLC_DI is provided with the FLC applicability of expression for connection mode UE.
In step 431, the connection mode UE on NPL 408 operates according to the FLC_DI that is provided with in the FLC notification message.If FLC_DI is set to ' N ', then connection mode UE reselects to PL409 based on the PL 409 that measures.If FLC_DI is set to ' Y ', then connection mode UE will be chosen in ongoing business service on the current frequency and by one in the MBMS service of FLC notification message indication according to level of priority.If selected the MBMS service, then connection mode UE stops the dedicated service service and reselects to PL according to the measurement of PL 409.On the other hand, if selected the dedicated service service, then connection mode UE continues this dedicated service service and does not carry out the sub-district and reselect on current frequency.
Simultaneously, based on receiving the FLC notification message, if the signal strength measurement of PL 409 is fully, then the idle pulley UE on NPL 408 be transformed into PL 409 and no matter FLC_DI how.
Before the MBMS session began, 410 couples of RNC were about to receive the number of the UE of MBMS service and count, the type of decision channel, and between step 431 and 441, set up radio bearer.
Along with MBMS session in step 441 begins, RNC 410 periodically transmits the FLC notification message for the MBMS session so that be supported in the mobility of the UE in the sub-district under RNC 410 controls in step 451 and 452.Based on receiving periodic FLC notification message, when needs, the UE on NPL408 is provided with based on the service ID in the FLC notification message, preferred frequency information, FLC_DI and carries out the sub-district and reselect to PL 409.Therefore, they can receive the MBMS service at present.
In the above-described embodiments, when being set to the mark of a bit, FLC_DI is provided with that indication FLC is applied to or FLC is limited to be used for the UE of connection mode, the mark of this bit can be with representing that the mark for a bit of the applicability that is in the UE under the specific RRC state replaces, or with representing for 4 bit map of the FLC applicability that is in the UE under each connection mode state or the integer replacement of 2 bits.
In this way, the UE of connection mode can utilize from FLC_DI and the PL Resource Availability knowledge of the interested MBMS service that is obtained is set and carry out FLC effectively.
Fig. 7 is the block diagram that is used to transmit the RNC of MBMS preferred frequency information according to embodiments of the invention.This RNC comprises radio resource manager 710, FLC controller 720, message conveyer 730.The broadcasting conveyer that is used to transmit the MBMS broadcast data does not illustrate therein.
With reference to figure 7, radio resource manager 710 is the cell management radio resource under its control, and measures the amount of radio resources that can use for each frequency in the sub-district.FLC controller 720 determines whether the radio resource of the PL of the specific MBMS service through measuring is enough to supply the business that is associated with the ongoing dedicated service service of connection mode UE.Dedicated service service right and wrong MBMS service.More clearly, FLC controller 720 is considered the number of the connection mode UE that adds the MBMS service on NPL, perhaps be in the number of the connection mode UE under the particular state, determine the business that is associated that whether can supply connection mode UE through the radio resource of measuring.FLC controller 720 is provided with the MBMS preferred frequency information according to the result who determines.That is to say that FLC controller 720 determines will begin for it PL of the MBMS service of session, simultaneously, determine in the MBMS preferred frequency information, whether to comprise PL service restricted information.If radio resource is enough to supply the business that is associated of connection mode UE, then the MBMS preferred frequency information does not comprise PL service restricted information, otherwise then comprises.For example, the PL restricted information when being changed to ' Y ', FLC_DI is arranged.In another embodiment of the present invention, FLC controller 720 can comprise in the MBMS preferred frequency information that PL serves the decision of restricted information and be made at according to different standard (criteria) for example about the service strategy of MBMS or service provider's selection.Message conveyer 730 resembles the FLC notification message by comprising the general information that is associated with available MBMS service, transmits the MBMS preferred frequency information.
Comprise in the MBMS preferred frequency information under the situation of PL service restricted information that the broadcasting conveyer does not preferably provide any non-MBMS service on the PL of MBMS service.On the contrary, when not having PL service restricted information, the broadcasting conveyer can provide non-MBMS service on the PL of MBMS.
Fig. 8 is the block diagram that is allowed to use the UE of PL according to an embodiment of the invention for MBMS service.This UE comprises message receiver 810, service controller 820, data sink 830.
