Technical field

The present invention relates to terminal measuring technique and broadcast group broadcast technology in the 3-G (Generation Three mobile communication system) (3G, The 3rd Generation), especially relate to a kind of terminal measuring method and user terminal based on receiving broadcast multicase control information.

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 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 user terminal (UE, User Equipment) 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 ControlChannel) receiving control information, and by Dedicated Traffic Channel (DTCH, Dedicated TrafficChannel) 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, MBMSpoint-to-multipoint Traffic Channel) receiving data information, and by the MBMS point to multiple spot control channel (MCCH, MBMS point-to-multipoint Control 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 sends based on fixed schedule, 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 comprises the MBMS access information.

MCCH information is based on the fixed schedule transmission, and complete MCCH information was periodically sent based on " repetition period ", to improve reception reliability.And " modification cycle " be the integral multiple of " repetition period ", critical message can be modified when only MCCH information sends for the first time in the modification cycle; Begin UTRAN in each modification cycle and can send MBMS modification information, be included in the MBMS service identification that MCCH information is modified in this modification cycle in this modification information; MBMS modification information each repetition period in this modification cycle repeats once at least; But not critical message can be modified at any time.In addition, the MBMS access information was periodically sent based on " access information cycle ", and " repetition period " is the integral multiple in " access information cycle ".Concern schematic diagram between " repetition period " during specifically being illustrated in figure 1 as UTRAN and sending MCCH information, " modification cycle " and " access information cycle ".

Wherein the value for modification cycle, access information cycle, repetition period is followed successively by:

Modification cycle _ modification periodic coefficient m scope: (7 ... 10), revise cycle MP=2 ^m* frame length.

Access information cycle access information periodic coefficient a scope: (0 ... 3), access information cycle AIP=(MP/2 ^a) * frame length.

The repetition period _ repetition period coefficient r scope: (0 ... 3), repetition period Rp=(MP/2 ^r) * frame length.

User terminal obtains the information of relevant MBMS business by receiving MCCH information in the sub-district, also knows the access information of business interested by the access information in the reception MCCH information, sends the MBMS service requesting information based on this access information to UTRAN.

The FDD terminal that wherein receives MBMS PTM business may not be used the whole different frequency/different system measurement time that calculates according to formula (1) to carry out different frequency/different system measurement and handle in order to guarantee the demodulation performance requirement to the MBMS business that receives.Generally speaking, reception MTCH goes up the FDD terminal of the MBMS PTM business of carrying and should use the portion of time in the N frame Measuring Time that calculates according to above-mentioned formula (1) to carry out the different frequency/different system measurement processing, thereby satisfy the demodulation performance requirement to the MBMS business that receives, the FDD terminal can be used 25% the carrying out different frequency/different system measurement and handle of TTI time of the MTCH that carries MBMS PTM business to greatest extent usually.

In the 3GPP standard, be in user terminal under the CELL_FACH state at the different frequency/different system measurement that calculates according to above-mentioned formula (1) in the time, if both needed to receive the MCCH information that UTRAN issues, needing to carry out different frequency/different system measurement again handles, just need user terminal to receive MCCH information, measure processing and interrupt carrying out the different frequency/different system cell, only require that the measurement performance that can guarantee the different frequency/different system cell requires to get final product.

The user terminal that is at present under the CELL_FACH state receives the MBMS business, just must receive the MCCH information that UTRAN issues, when simultaneously user terminal judges that according to the quality of reception of the current service cell at self place and/or systematic survey control information that UTRAN issues obtaining needs carries out different frequency/different system measurement and handle, generally carry out according to following process:

User terminal is at first according to the requirement of above-mentioned formula (comprising that formula 2 is to formula 15) and form, determine to carry out the measurement performance time requirement that the different frequency/different system cell is measured, promptly to finish the identification of new different frequency/different system cell at the appointed time, and will report high level to the measurement result of different frequency/different system cell by physical layer at the appointed time;

User terminal suspends the measurement to the different frequency/different system cell, changes and goes to receive MCCH information;

Simultaneously user terminal also will be finished the identification to new different frequency/different system cell in above-mentioned definite measurement performance time requirement, and will report high level to the measurement result of different frequency/different system cell by physical layer.

At present, the measurement performance time requirement that the user terminal of being determined by above-mentioned formula and form is measured the different frequency/different system cell, be not consider that fully user terminal is receiving MCCH information and carrying out the different frequency/different system cell and measure when taking place simultaneously, need to suspend the different frequency/different system cell is measured, obtain and go to receive this situation of MCCH information.Therefore in actual process, user terminal is to be difficult to accomplish accurately to receive MCCH information, can in measurement performance time requirement, finish identification again to new different frequency/different system cell, and will report high-rise by physical layer to the measurement result of different frequency/different system cell, thereby make user terminal when receiving MCCH information, need suspend measurement, simultaneously two technical processes that also will satisfy measurement performance time requirement are handled in the measurement of different frequency/different system cell and existed contradiction the different frequency/different system cell.

Embodiment

The main design philosophy of the terminal measuring method that the present invention proposes is to take all factors into consideration the time of reception of broadcast multicase control information and the different frequency/different system cell is carried out the time that different frequency/different system measurement is handled, utilizing UTRAN is the characteristic that repeats to send same broadcast multicase control information in each repetition period in a modification cycle, issue in each time period of time-interleaving thereby be arranged on broadcast multicase control information, can make user terminal needn't use the complete time that issues receiving broadcast multicase control information, be used for carrying out the different frequency/different system measurement processing but in each overlapping time period, reserve portion of time, user terminal can merge processing with the part broadcast multicase control information that receives in a plurality of broadcast multicase control informations that repeat to send like this, thereby realize receiving the purpose of complete broadcast multicase control information, thereby also can make user terminal the measurement of different frequency/different system cell be satisfied the measurement performance time requirement of stipulating in the standard, promptly realized making user terminal can receive complete broadcast multicase control information, under the prerequisite of the different frequency/different system measurement performance time requirement that can in satisfying standard, stipulate again, finish the identification of new different frequency/different system cell and measurement result is reported high level, thereby having solved user terminal in the prior art and be receiving broadcast multicase control information need suspend determining in the measurement of different frequency/different system cell and the existing standard that user terminal carries out the measurement performance time requirement of different frequency/different system cell and do not consider that user terminal need suspend the repugnance that the measurement of carrying out the different frequency/different system cell exists when the receiving broadcast multicase control information.

Be explained in detail below in conjunction with the main realization principle and the embodiment thereof of each accompanying drawing the present invention program.

Please refer to Fig. 2, this figure is the main realization principle flow chart that the present invention is based on the terminal measuring method of receiving broadcast multicase control information, and its main implementation procedure is as follows:

Step S10, the systematic survey control information that user terminal UE issues according to UTRAN, calculate and determine the different frequency/different system cell is carried out the different frequency/different system measurement time that different frequency/different system measurement is handled, wherein UE calculates the different frequency/different system measurement time according to following formula:

SFN div N=C_RNTI mod M_REP+n * M_REP (formula 1)

In its Chinese style:

N is the Secondary Common Control Physical Channel (SCCPCH of the non-MBMS logic channel of the carrying of terminal monitoring, Secondary Common Control Physical Channel) on the emission maximum time interval (TTI is arranged, Transmission Timing Interval) TTI of FACH is divided by 10ms, and this section period is the time remaining length that user terminal carries out different frequency/different system measurement;

Cycle period at interval, M_REP=2 are measured in the M_REP representative ^kBy following formula, the repetition period of the Measuring Time of a N frame is N * M_REP frame; Wherein k is that FACH measures cycle period coefficient at interval, can read in system information 11 or 12 contained information elements " FACH measurement occasion info ";

C_RNTI (cell radio network temporary identity) is the C-RNTI value of user terminal;

N=0,1,2 ..., as long as SFN is lower than its maximum.

Step S12, the UE judgement repeats to send in the modification cycle of same broadcast multicase control information at UTRAN based on the repetition period, whether the Measuring Time of the execution different frequency/different system measurement that aforementioned calculation is determined exists overlapping (being that different frequency/different system measurement is handled and UTRAN issues the situation that the broadcast multicase control information existence is carried out simultaneously) with the time that UTRAN issues broadcast multicase control information, if carry out following step S14; Otherwise finish.

Step S14, UE respectively will be in the modification cycle each overlapping time period be divided into Measuring Time part and time of reception part; Wherein UE need divide each overlapping time period according to following criteria for classifying:

1. guarantee partly to satisfy the measurement performance time requirement of the different frequency/different system cell being carried out measurement from the Measuring Time that each overlapping time period marks off, when carrying out different frequency/different system measurement in the Measuring Time part that to be UE mark off in each overlapping time period and handling, should be able to finish identification at the appointed time in the length according to the regulation (being the regulation of above-mentioned formula 2～formula 15 of the prior art and list data thereof) of existing standard, or finish the high level that measurement result is reported UE by the physical layer of UE in the length at the appointed time new different frequency/different system cell;

2. guarantee partly to satisfy the requirement of complete this broadcast multicase control information of reception from the time of reception that each overlapping time period marks off, the each several part broadcast multicase control information that receives in the time of reception part that to be UE mark off in each overlapping time period, can combine, form the broadcast multicase control information that complete needs receive.

In addition, the different frequency/different system measurement time span at the Measuring Time part place that UE marked off in each overlapping time period also requires to be less than 25% of Transmission Time Interval (TTI, the Transmission Timing Interval) length that equals the broadcasting multicast service channel.

Preferably, UE can be arranged on the Measuring Time part and the time of reception part that mark off in each overlapping time period and be alternately state arrangement on the axle at one time, for example in first section overlapping time, with the first half time as the Measuring Time part, the latter half time is as the time of reception part; Then in second overlapping time section, with the first half time as the time of reception part, the latter half time is as the Measuring Time part, section just can realize that the Measuring Time part that will mark off and time of reception part are on the axle at one time and replaced the state arrangement thereby be provided with so follow-up overlapping time.

Step S16, UE carries out different frequency/different system measurement based on the above-mentioned Measuring Time part that marks off to the different frequency/different system cell and handles; Wherein UE also will be based on the measurement to the different frequency/different system cell, the different frequency/different system cell that identification makes new advances under the prerequisite of the measurement performance time requirement (the relevant determined value of above-mentioned formula 2～formula 15 of the prior art and list data thereof) of stipulating in satisfying existing standard; Perhaps

UE also will will report high level to the measurement result that different frequency/different system cell execution different frequency/different system measurement is handled by physical layer under the prerequisite of the measurement performance time requirement (the relevant determined value of above-mentioned formula 2～formula 15 of the prior art and list data thereof) of stipulating based on the measurement to the different frequency/different system cell in satisfying existing standard.

Step S18, the broadcast multicase control information that the time of reception part that UE marks off based on above-mentioned issues UTRAN receives, and wherein the detailed process that receives of the broadcast multicase control information that UTRAN issued based on the above-mentioned time of reception part that marks off of UE can be as follows:

The time of reception that UE marks off in each overlapping time period respectively partly receives the broadcast multicase control information (broadcast multicase control information that UE partly receives at each time of reception might be incomplete same) that UTRAN issues;

UE will be treated as the complete broadcast multicase control information that will receive in the broadcast multicase control information merging that each time of reception partly receives again.

Wherein in the said method mentioned broadcast multicase control information can but be not limited to multimedia broadcasting and multicast point-to-multipoint service control information (being MCCH information).

Mentioned user terminal UE can be for working in the user terminal under the mode of frequency division duplexing (FDD) in the said method, also can be for working in the user terminal under the TDD mode (TDD).

A specific embodiment is as follows:

1, UE receives the MBMS business, just must receive the MCCH information that UTRAN issues, UE judges according to the quality of reception of the current service cell at self place and/or systematic survey control information that UTRAN issues and obtains needs execution different frequency/different system measurement processing (utilizing above-mentioned formula of the prior art 1 to calculate judgement) simultaneously;

2, UE determines to carry out the measurement performance time requirement that different frequency/different system measurement is handled according to the regulation of above-mentioned formula 2～formula 15 of the prior art and relevant list data thereof;

3, UE arranges to carry out the Measuring Time that different frequency/different system measurement is handled, the concrete arrangement scheme is: consider that UTRAN is based on the repetition period and repeats to send MCCH information in a modification cycle, for in a modification cycle, measuring the MCCH information that issues simultaneously of handling with the different frequency/different system cell, only use portion of time to carry out different frequency/different system measurement in some overlapping time periods and handle, another part time is carried out the reception to this MCCH information; And overlapping other use in the time period and above opposite time portion receive the MCCH information processing and carry out the processing of different frequency/different system cell.UE finally will make up the MCCH information that receives from a plurality of time portion, to obtain the complete MCCH information that will receive.

The Measuring Time that wherein UE arranges in the section the different overlapping times in a modification cycle is used to carry out different frequency/different system measurement will satisfy the measurement performance time requirement of existing standard to different frequency/different system measurement, being used to of arranging simultaneously receives the time of reception of MCCH information and will guarantee that UE can receive fully and the complete MCCH information that obtains needs reception, the different frequency/different system measurement time span that also will guarantee each Measuring Time place of arranging simultaneously be no more than MTCH TTI length 25%.

Please refer to Fig. 3, this figure is based on the inventive method in the same modification cycle, each section that different frequency/different system measurement time and MCCH information is issued time-interleaving divided the schematic diagram of processing overlapping time, the first line display UE is normally receiving the MCCH information that UTRAN issues among the figure, second behavior receives MCCH information according to the inventive method, and the different frequency/different system cell carried out the view that different frequency/different system measurement is handled, wherein suppose UE calculate to the different frequency/different system cell carry out Measuring Time that different frequency/different system measurement handles respectively with the repetition period in UTRAN to issue time of MCCH information overlapping fully respectively, then that each is the overlapping time period is divided into Measuring Time part and time of reception part, wherein on behalf of UE, white portion the different frequency/different system cell is carried out the Measuring Time part that different frequency/different system measurement is handled, the time of reception part that the MCCH information that on behalf of UE, black region UTRAN is issued receives, wherein the division of black block part will guarantee the MCCH information that UE can the complete UTRAN of receiving issues.

4, UE finishes the identification to the new sub-district of different frequency/different system in the measurement performance time requirement of existing regulation and stipulation, or the physical layer of UE will report the high level of UE to the measurement result that different frequency/different system cell execution different frequency/different system measurement is handled; Simultaneously UE is complete receives the MCCH information that UTRAN issues.

Wherein can concern in no particular order between above-mentioned steps 1 and the step 2.

As fully visible, the terminal measuring method that the present invention proposes, can be in the modification cycle that MCCH information issues, reasonably time-interleaving each time period together that different frequency/different system measurement time and UTRAN issue MCCH information is reasonably adjusted and divides by UE, thereby can guarantee the MCCH information that UE can the accurately complete UTRAN of receiving issues, can guarantee that again UE measures identification to the new sub-district of different frequency/different system in the different frequency/different system measurement performance time requirement of regulation and stipulation, the measurement result that maybe will carry out the measurement of different frequency/different system cell reports high level.
