Description
Technical field
The present invention relates to the service combining treatment technology in the 3-G (Generation Three mobile communication system) (3G, The 3rd Generation), especially relate to a kind of merging method and user terminal thereof of broadcasting multicast service.
Background technology
Universal mobile telecommunications system (UMTS, Universal Mobile Telecommunications System) is to adopt the 3-G (Generation Three mobile communication system) of WCDMA air interface technologies, mainly is to organize among the 3GPP in the WCDMA/GSM global standardsization to develop.
Wherein in 3GPP UMTS standard, according to Radio Resource control (RRC, Radio ResourceControl) whether connection sets up, user terminal can be divided into free time (Idle) pattern and be connected two kinds of (Connected) patterns with RRC: wherein not with UMTS universal land radio access web (UTRAN, Universal Terrestrial Radio Access Network) sets up the user terminal that RRC connects and be in the Idle pattern, user terminal under this pattern can only pass through Non-Access Stratum (NAS, Non-Access Stratum) sign is distinguished, as distinguishing by international travelling carriage identifier (IMSI, International Mobile subscriberidentity); Wherein set up the user terminal that RRC is connected with UTRAN and be in the RRCConnected pattern, user terminal under this pattern has been assigned with Radio Network Temporary Identifier (RNTI, Radionetwork temporary identity), with as the sign of this user terminal on Common transport channel.
And for the user terminal of RRC Connected pattern, the transmission channel kinds that can use according to the level and the user terminal of RRC connection is divided into different conditions with user terminal again: wherein the user terminal under CELL_PCH state, CELL_FACH state and the CELL_DCH state can be distinguished on the level of sub-district, user terminal under the URA_PCH state can be distinguished on UTRAN Registration Area (URA, UTRAN RegisterArea) level.Wherein the user terminal under the CELL_DCH state has been assigned with special-purpose physical channel, and user terminal can use dedicated transmission channel and shared channel and their combination; User terminal under the CELL_FACH state is at the descending Common transport channel of continuous monitoring (FACH, Forward Access Channel) of wanting, at the up default common signal channel (RACH, ReverseAccess Channel) that is assigned with; User terminal under CELL_PCH and the URA_PCH state adopts discontinuous reception (DRX, Discontinuous Reception) mode is by relevant Page Indication Channel (PICH, PageIndicator Channel) paging channel (PCH of monitoring, Page Channel), the user terminal under this two states is without any up activity.
In the 3GPP standard, the regulation user terminal need be measured co-frequency neighbor cell.Wherein under the obsolete situation of Hierarchical Cell Structure (HCS, hierarchy cell structure), the criterion that user terminal carries out common frequency measurement is as follows:
If Sx＞Sintrasearch, then user terminal may select not carry out common frequency measurement;
If Sx≤Sintrasearch, then user terminal is carried out common frequency measurement;
If current service cell does not send Sintrasearch, then user terminal is carried out common frequency measurement.
Parameter S intrasearch in the wherein above-mentioned criterion represents the common frequency measurement threshold value, and this common frequency measurement threshold values is sent by system broadcasts by the current service cell of user terminal.
Wherein in above-mentioned common frequency measurement criterion, according to the current cell type difference that is operated in of user terminal, above-mentioned parameter Sx represents following meanings respectively:
When the current cell type that is operated in of user terminal was the FDD sub-district, Sx represented Squal, wherein:
Squal=Q
Qualmeas-Qqualmin; (in the 3GPP standard, this formula being referred to as the S criterion)
When the current cell type that is operated in of user terminal was the TDD sub-district, Sx represented Srxlev, wherein:
Srxlev=Q
Rxlevmeas-Qrxlevmin-Pcompensation; (in the 3GPP standard, this formula being referred to as the S criterion)
The concrete implication of each parameter is as shown in the table in above-mentioned two formula:
| Squal | The cell selecting quality only is applicable to the FDD sub-district |
| Srxlev | Cell selecting receives level |
| Q qualmeas | The cell quality that measures only is applicable to the FDD sub-district |
| Q rxlevmeas | The sub-district reception level that measures |
| Qqualmin | Desired minimum mass level only is applicable to the FDD sub-district in the sub-district |
| Qrxlevmin | Desired minimum reception level in the sub-district |
| Pcompensation | Max(UE_TXPWR_MAX_RACH-P_MAX，0) |
| UE_TXPWR_MAX_RACH | The maximum transmission power that UE may use when inserting the sub-district by RACH |
| P_MAX | UE maximum radio frequency transmitting power |
Above common frequency measurement criterion only is applicable to that user terminal UE is in idle, and the common frequency measurement in URA_PCH and CELL_PCH state following time is handled; Wherein UE is in CELL_FACH state following time and should constantly measures the co-frequency cell that has recognized and search for new co-frequency cell; At Idle, URA_PCH, CELL_PCH and CELL_FACH state following time, the common frequency measurement sub-district that the co-frequency cell that user terminal UE only need consider to carry out forced measurement according to above common frequency measurement criterion will be considered during as the sub-district gravity treatment.
Under the situation that HCS uses, the criterion that user terminal carries out common frequency measurement is as follows:
For the user terminal that is not in high-speed mobile:
If (Srxlev≤SsearchHCS) or (if user terminal is a fdd mode terminal and Sx≤Sintersearch), then user terminal UE measures all co-frequency cells and alien-frequency district; Else if (Sx＞Sintrasearch), then user terminal high all co-frequency cells and the alien-frequency district of HCS priority that only contrast current service cell measured; If (Sx≤Sintrasearch), then user terminal pair co-frequency cell that equates with the HCS priority of current service cell and alien-frequency district or all co-frequency cells and the alien-frequency district higher than the HCS priority of current service cell are measured.
If current service cell does not send Sintrasearch, then user terminal carries out common frequency measurement to all co-frequency cells, and all high alien-frequency districts of HCS priority of contrast current service cell carry out different-frequency measure.
If current service cell does not send SearchHCS, or user terminal when being the fdd mode terminal and current service cell do not send Sintersearch, then user terminal is measured all co-frequency cells and alien-frequency district.
For the user terminal that is in high-speed mobile:
If (Srxlev≤SsearchHCS) or (if user terminal is fdd mode terminal and Sx≤Sintersearch), or current service cell does not send SearchHCS, or user terminal when being the fdd mode terminal and current service cell do not send Sintersearch, then user terminal is measured all co-frequency cells and alien-frequency district.Otherwise for other situations, user terminal pair co-frequency cell that equates with the HCS priority of current service cell and alien-frequency district or all co-frequency cells and the alien-frequency district lower than the HCS priority of current service cell are measured.
Parameter S intrasearch in the wherein above-mentioned common frequency measurement criterion represents the common frequency measurement threshold value, parameter S intersearch represents the different-frequency measure threshold value, measurement threshold value when parameter S searchHCS represents HCS, wherein parameter S intrasearch, Sintersearch and SsearchHCS carry out broadcast transmission by the current service cell system respectively.
Above-mentioned common frequency measurement criterion only is applicable to that also user terminal UE is in idle, and the common frequency measurement in URA_PCH and CELL_PCH state following time is handled; Wherein UE is in CELL_FACH state following time and should constantly measures the co-frequency cell that has recognized and search for new co-frequency cell; At Idle, URA_PCH, CELL_PCH and CELL_FACH state following time, the common frequency measurement sub-district that the co-frequency cell that user terminal UE only need consider to carry out forced measurement according to above common frequency measurement criterion will be considered during as the sub-district gravity treatment.
Simultaneously, be accompanied by the development of 3G (Third Generation) Moblie technology, the user no longer is satisfied with speech business to the demand of mobile communication business, because 3-G (Generation Three mobile communication system) can provide the message transmission rate higher than second generation mobile communication system, therefore a large amount of multimedia services just emerges, such as: services such as Internet network are downloaded, browsed at a high speed to visual telephone, picture.Wherein, some applied business require a plurality of users can receive identical data simultaneously, such as: business such as video request program, television broadcasting, video conference, online education, interactive game.
In order effectively to utilize the mobile communications network resource, 3-G (Generation Three mobile communication system) has been introduced the notion of multicast and broadcasting, and multimedia broadcast/multicast service is a kind of technology that transmits identical data from a data source to a plurality of targets.Thus, the WCDMA/GSM global standardsization organize 3GPP to propose multimedia broadcast/group broadcast service (MBMS, Multimedia Broadcast/Multicast Service), so-called MBMS provides a data source to send the point-to-multipoint service of identical data to a plurality of users in mobile communications network, share to realize Internet resources, improve utilization rate of network resource, the utilance of the interface resource of especially eating dishes without rice or wine.
The data-transmission mode of MBMS business between UE and UTRAN can be divided into two kinds: point-to-point (PTP, Point to Point) pattern and put multiple spot (PTM, Point to Multipoint) pattern.Wherein ptp mode is used for the multicast pattern of MBMS, user terminal under the RRC connection mode under the multicast pattern is by Dedicated Control Channel (DCCH, Dedicated Control Channel) receiving control information, and by Dedicated Traffic Channel (DTCH, Dedicated Traffic Channel) receiving data information.And the PTM pattern is used for broadcasting or the multicast pattern of MBMS, user terminal under this pattern is by MBMS point-to-multipoint service channel (MTCH, MBMS point-to-multipoint Traffic Channel) receiving data information, and by the MBMS point to multiple spot control channel (MCCH, MBMS point-to-multipointControl Channel) receiving control information.
Wherein the control information of MBMS business under the PTM pattern issues by MCCH, the MBMS control information that issues on MCCH comprises business information, access information and radio bearer information etc., the MBMS control information that below will send on MCCH for the sake of simplicity, abbreviates " MCCH information " as.MCCH information is divided into two kinds of critical message and non-critical information: critical message comprises MBMS information of adjacent cells, MBMS business information and MBMS radio bearer information; Non-critical information is the MBMS access information.
User terminal obtains the MBMS business information that can get by receiving MCCH information in the sub-district; Also know the access information of business interested, and send request to UTRAN based on this access information by the MBMS access information in the reception MCCH information.
Receive the gain of MBMS PTM business and strengthen covering in order to improve user terminal, user terminal can adopt the merging mode to come the MBMS PTM business that receives from different sub-districts is merged processing, be that user terminal can receive the same MBMS RB bit stream from different districts, and the MBMSRB bit stream that receives is merged processing.
Wherein user terminal can adopt two kinds of merging modes to merge processing to the same MBMS PTM that receives from different sub-districts is professional: select to merge and soft merging.Also may comprise the soft combination situation of part in the wherein soft merging.Selecting to merge is to carry out at Radio Link control (RLC, Radio Link Control) layer, and soft merging is carried out in physical layer.These two kinds of merging modes are applied in user terminal and receive under the different situation of minizone time difference of same MBMS PTM business from different sub-districts, the delay inequality that its soft merging usually is applied to receive between the different districts of same MBMS PTM business is a Transmission Time Interval (TTI to the maximum, Transmission Time Interval)+and the situation of 1 time slot [being the 1TTI+1 time slot], it is selected to merge and usually is applied to than the bigger situation of delay inequality between soft merging different districts of living in.
If when selecting merging or soft merging to carry out between the different districts of transmission same MBMS PTM business, UTRAN should issue the MBMS information of adjacent cells of adjacent sub-district to user terminal UE, and the MBMS information of adjacent cells that this issues comprises and is used to select to merge or the radio bearer configuration information of the adjacent sub-district that soft merging is handled.When the soft merging of part is used, also comprise physical layer (L1) in the MBMS information of adjacent cells that UTRAN issues and merge schedule information simultaneously, be used to indicate UE to carry out the concrete moment of the same MBMS PTM business of adjacent sub-district of soft merging and current service cell transmission.
Had the MBMS information of adjacent cells, the MTCH that UE just can receive adjacent sub-district goes up data carried by data information, and need not receive the upward control information of carrying of MCCH of this neighbour sub-district.When user terminal UE received the MBMS information of adjacent cells of the adjacent sub-district that UTRAN issues, UE can determine suitable adjacent sub-district based on the signal quality that measures and be used for that follow-up selection merges or soft merging is handled.If user terminal UE has determined adjacent sub-district is selected to merge or soft merging when handling, and user terminal UE has the correct MBMS information of adjacent cells of corresponding adjacent sub-district at this moment, and user terminal will merge the selection of current service cell and adjacent sub-district execution MBMS PTM business or soft merging is handled.
Wherein handle for the merging of supporting MBMS PTM business, UTRAN need periodically issue one or more MBMS Neighboring cell PTM RB information information, this information is the adjacent sub-district of MBMS P-T-M wireless loading information, the PTM beared information of the one or more MBMS business of using with the present adjacent sub-district of notice UE that are used for soft merging or select to merge.
For the MBMS business, for guaranteeing the resources effective utilization, in the 3GPP standard, introduced the notion of MBMS preferential frequencies layer, wherein MBMS preferential frequencies layer promptly refers in order effectively to utilize resource, the user terminal that the UTRAN side requires to receive certain MBMS business is preferentially chosen on certain frequency layer, UTRAN sends this MBMS business on this frequency layer, and the preferential frequencies layer of each MBMS business is specifically indicated to user terminal by UTRAN.The user terminal that wherein receives the MBMS business will quarter in the indicated preferential frequencies layer sub-district of UTRAN as much as possible.In order to guarantee the mobility of user terminal, user terminal can carry out cell reselection process in the process that receives the MBMS business in addition.
In present research, be in idle, CELL_PCH, URA_PCH and CELL_FACH state, and receiving the FDD terminal that MTCH goes up the MBMS PTM business of carrying is to discern the co-frequency cell of measuring, and the co-frequency cell that identifies is used for the MBMS PTM service combining that MTCH goes up carrying handles.In addition, when if the co-frequency cell number that goes out when the FDD terminal recognition exceeds the merging ability of FDD terminal, then need each co-frequency cell that to identify to sort, be used for the merging that MTCH goes up the MBMS PTM business of carrying and handle to select the corresponding preferably co-frequency cell of the MTCH quality of reception according to the result after the ordering according to the quality of reception of MTCH.
But present research only concentrates on the FDD terminal, only consider the FDD terminal can be used for the co-frequency cell that the MBMS PTM service combining that identifies, can participate in self receiving is handled to carry on the MTCH in the common frequency measurement process MBMS PTM service combining processing, do not have common frequency measurement in the user terminal (as the TDD terminal etc.) of other mode of operations and select can participate in MTCH is gone up the co-frequency cell that the MBMSPTM business of carrying merges processing and be in, carry out the ability of MBMS PTM service combining processing.
