Seeing also Fig. 7 and Fig. 9, the mode of operation at wireless terminal is set to the feelings of CSFB pattern Under condition, default configuration is that the second antenna 122 is connected to the second communication unit port 1313.

In the work process of wireless terminal, according to current communication mode and the type of service of wireless terminal Switch and couple relation between the second antenna 122 and communication unit 110.

Specifically,

In step S910, search the net resident stage in start, configure the second antenna 122 and be connected to second Communication unit port 1313；

In step S920, after resident success, the first communication pattern (LTE communication pattern) and second Communication pattern (2G/3G communication pattern) is in normal Standby state, terminal to report network its have Its support of CSFB ability, i.e. terminal notification network has in LTE network and the access of 2G/3G network Ability.Here normal Standby refers to normally receive cell system message and broadcast, paging disappear Breath, meets 3GPP agreement 25.304 the most resident (Normal Camping) condition.Here terminal Report LTE network to have CSFB ability idiographic flow and refer to 3GPP24.301 agreement；

In step S940, it is judged that whether the second communication pattern initiates circuit domain business, if it is, enter Enter S950, otherwise return S930；

In step S950, in the case of the second communication pattern initiates circuit domain business, configure second Antenna 122 is connected to the second communication unit port 1313, here circuit domain business include voice caller, Speech business is called and location area updating etc..Second communication pattern returns to holding state, enters S930；

It will be understood to those skilled in the art that in above-mentioned detailed description of the invention, when LTE communication pattern During with 2G/3G communication pattern all in IDLE state, LTE communication pattern and 2G/3G communication pattern Time-division uses diversity antenna, is used for receiving paging and measurement；Shape is connected when LTE communication pattern is in PS When state and 2G/3G communication pattern are in IDLE state, LTE communication pattern independently uses main antenna, point Collection antenna passes through time division way for LTE communication pattern and 2G/3G；When LTE communication pattern is in PS connection status or IDLE state, 2G/3G communication pattern initiates CS(Circuit Switched Domain, circuit domain) business time, LTE communication pattern only uses main antenna to receive and dispatch, is cut by diversity antenna Give 2G/3G communication pattern to receive and dispatch for business.

For the process in above-mentioned S930, refer to Figure 10, comprise the steps:

In step S1010, the first communication pattern and the second communication pattern are in normal Standby shape State；

In step S1020, calculate the first communication pattern paging according to systematic parameter respectively and receive opportunity With the opportunity of measurement, measurement opportunity that the second communication pattern is corresponding.Here systematic parameter refers to corresponding communication Measurement parameter in cell system message and paging channel configuration, paging occasion configuration parameter under pattern；

Citing, provides the second communication pattern as a example by GSM and measures timing parameters.GSM is in IDLE Need under state GSM BCCH(Broadcast Control Channel, BCCH) Receiving, GSM RSSI(Received Signal Strength Indicator, received signal strength refers to Show) measure, initial BSIC(Base Station Identity Code, base station identity code) differentiate, BSIC heavily confirms.Following interval reception scheme can be used: for GSM according to GSM frame structure BCCH receives, and rssi measurement, initial BSIC differentiate, BSIC heavily confirms, can use 240ms For the cycle, each reception time is that the scheme of 6ms is received.

It will be understood to those skilled in the art that in above-mentioned detailed description of the invention, terminal to report network has There is CSFB ability, and preferentially reside in LTE network.In the present invention, terminal is in resident LTE network While, additionally it is possible to reside in 2G/3G network, including measuring 2G/3G community and synchronizing, read system System message, carry out location area updating etc., therefore when initiating circuit domain call (include caller and called) feelings Under condition, compared with existing CSFB flow process (as shown in Figure 11 A), it is possible to avoid 2G/3G community Synchronization, measurement, read system message and possible location area updating flow process, therefore, it is possible to reduce exhale It is setup delay.Under LTE standby mode, the flow process initiating circuit domain call sees accompanying drawing 11B:

Step S1110: wireless terminal (also referred to as user terminal User Equipment(UE) or mobile Platform Mobile Station(MS)) send the request of activating business (Extend Service Requet) to network Message, request CS business falls after rise；

Step S1120: receive and process RRC(Radio Resource Control, Radio Resource control Agreement processed) Connection Release (RRC Connection Release) message；

Step S1130: initiate CS at 2G/3G network according to the 2G/3G cell information that UE safeguards Call setup；

In above-mentioned steps S1130, existing protocol is speed call Establishing process, connects at RRC and releases Putting and may comprise redirection message in message, the cell system such as frequency including 2G/3G Target cell disappears Breath.UE initiates to exhale without this information, the 2G/3G community directly using UE to safeguard in the present invention Cry.

Another embodiment, owing to terminal of the present invention can be under two kinds of communication patterns of LTE and 2G/3G Standby, therefore under LTE standby mode, initiate circuit domain call time ignore above-mentioned S1110 and S1120, directly initiates calling by S1130, it is achieved faster initiate audio call, ensure LTE simultaneously It is in normal Standby state.

For in the such as application scenarios shown in Fig. 9, inventor researches and develops discovery further, similar The antenna combination of S950 and the relation that couples of communication unit adjust process and signal transmission quality may be brought to ask Topic.

In detail, two antennas, wireless terminal are used when PS connection status due to LTE communication pattern Initiate to need the diversity reception antenna of LTE system is switched to 2G/3G completely during the CS business of 2G/3G System, the now reception of LTE communication pattern is become 1 antenna from 2 antennas, goes out for communication quality Now following impacts:

For PDCCH(Physical Downlink Control Channel, physical down controls letter Road), PCFICH(Physical Control Format Indicator Channel, physical control lattice Formula instruction channel) etc. control for channel, when there is the CS business of 2G/3G, the thing of wireless terminal Reason layer can adjust the reception controlling channel according to order, launches diversity owing to control channel uses, receives After antenna becomes one, antenna receives scheme and is become by 4TX/2RX or 2TX/2RX or 1TX/2RX Having become 4TX/1RX or 2TX/1RX or 1TX/1RX(TX to refer to that network-side sends, RX refers to that terminal connects Receive), simply receive diversity gain without, SNR(Signal to Noise Ratio, signal to noise ratio) root Have the decline of about 3dB according to multi-path environment, but the receptivity redundancy of control signal is relatively big, so SNR declines controlling channel reception impact little；

For PDSCH(Physical Downlink Shared Channel, physical down shares letter Road) MIMO(Multiple-Input Multiple-Output, have more) space division multiplexing transmission, more Two data blocks (TB) becoming causing PDSCH channel after 1 antenna receives are received from receiving 2 antennas Disturb each other, a large amount of error code occurs；For the transmission mode of other PDSCH channels, receive sky Line has a 3dB left side without reception diversity gain, SNR according to multi-path environment after being become 1 from 2 Right decline, still keeps the code modulation mode of former PDSCH channel to send to terminal due to LTE base station Data, therefore PDSCH channel also there will be error code.

For above-mentioned transmission quality problems, inventor, through creative work, proposes a kind of new process Mode.Specifically, when LTE communication pattern is in PS connection status, if wireless terminal needs also When row is initiated 2G/3G CS calling service, response CS called service or does CS territory location area updating, Under LTE communication pattern, stop using reception diversity antenna, it is switched to completely 2G/3G communication mould Formula is as sending and receiving antenna.Through certain processing procedure so that LTE network side is by LTE system PDSCH channel is to adapt to Dan Tian by the transmission mode Dispatching adjustment received under diversity or space division multiplexing channel Transmission mode under line reception.

Below by detailed description of the invention, the processing mode that this is new is illustrated.

Refer to Figure 12, be the structural representation of a kind of wireless terminal.

Wireless terminal includes: upper unit 1201, LTE physical layer element 1202 and antenna switching unit 130.Described LTE physical layer element 1201 includes under LTE physical layer control unit 12021, LTE Row CPR(CQI/PMI/RI, Channel Quality Indicator/Precoding Matrix Indicator/Rank Indicator, channel quality instruction/pre-coding matrix instruction/order indicates) measuring unit 12022, LTE physical layer receives unit 12023.

Wherein, described LTE physical layer control unit 12021 is for receiving from upper unit 1201 antenna switching command time, amendment LTE descending CPR measuring unit 12022 antenna measurement Configuration；Receiving after the renewal configuration information of network side, controlling described LTE physical layer and receive The more newly received configuration of unit 12023；

Described LTE descending CPR measuring unit 12022 is carried out under configuring in described antenna measurement CPR measures, and generates the measurement result reporting network side；

Described LTE physical layer receives unit 12023 and receives for the reception configuration according to described renewal The signal of automatic network side；

For receiving in described LTE physical layer, unit 12023 is more newly received joins described upper unit 1201 In the case of putting, control antenna switching unit 130 and carry out the switching of antenna links scenarios.

Wireless terminal is under the PS connection status of LTE communication pattern initiates CSFB operation flow and is divided into Space division multiplexing and two kinds of situations of non-space division multiplexing.Here space division multiplexing refers to logical multi-input multi-output, The incoherent feature space division multiplexing of fading characteristic between different antennae is utilized to transmit multichannel data.At LTE In, realizing space division multiplexing by 2X2MIMO and 4X2MIMO, i.e. 22, antenna is received or 42 Receiving, by space division multiplexing transmitting two paths data on a carrier wave, the PDSCH in LTE passes through MIMO realizes the transmission mode of two-way TB data space division multiplexing transmission mode 3(TM3): open loop MIMO space division multiplexing, transmission mode 4(TM4): closed-loop MIMO space division multiplexing and transmission mode 8 (TM8):: multiuser MIMO space division multiplexing.When PDSCH MIMO space division multiplexing is transmitted, by 2 antennas receive and become causing two TB data blocks of PDSCH channel to be done each other after 1 antenna receives Disturb, a large amount of error code occurs；

Here non-space division multiplexing refers to PDSCH only transmission of one line TB data block, in LTE TM1, TM2, TM3 single layer (Layer), single Layer and TM7 of TM4 broadly falls into non-NULL Divide multiplexing transmission pattern.For the transmission mode of non-space division multiplexing PDSCH channel, reception antenna Without receiving diversity gain after being become 1 from 2, SNR has about 3dB according to multi-path environment Decline, still keep the code modulation mode of former PDSCH channel to send to terminal due to LTE base station Data, therefore PDSCH channel also there will be error code, but due to physical layer HARQ(Hybrid Automatic Repeat Request, hybrid automatic repeat-request) retransmit merging, do not result in frequently RLC(Radio Link Control, wireless spread-spectrum technology) layer retransmit cause link step-out.

Referring to Figure 13, wireless terminal is in the PS connection status of LTE communication pattern and descending biography In the case of defeated pattern is non-space division multiplex mode, initiate the circuit domain business (bag of 2G/3G communication pattern Include caller and called) handling process include:

Step S1310: the second communication pattern initiates voice caller or called service request.

Step S1320: the second antenna is switched to the second communication pattern, is that the second communication pattern is special With.

Step S1330: judge whether to keep the first communication pattern data service, as kept, then enters Step S1340；Otherwise, step S13100 is entered.

In one implements, if the data service keeping the first communication pattern LTE can be to use Family is arranged by interface, it is also possible to be that terminal software independently judges that the ability of the second communication pattern realizes. Estimate of situation autonomous for terminal, if the second communication pattern is WCDMA or TD-SCDMA etc. Support the network that voice-and-data is concurrent, then judged result is not keep LTE data service；If the Two communication patterns are the network that GSM does not support data and speech concurrent, then judged result is to maintain LTE Data service.

Step S1340: initiate independent speech business at the second communication pattern；Simultaneously, step is entered S1350。

Step S1350: at the first communication pattern, the antenna measurement revising descending CPR measuring unit is joined Put.The upper unit of wireless terminal sends antenna switching command, LTE thing to LTE physical layer control unit The antenna measurement of descending for LTE CPR measuring unit is configured by original 4TX/2RX by reason layer control unit Or 2TX/2RX or 1TX/2RX is adjusted to 4TX/1RX or 2TX/1RX or 1TX/1RX, enter S1360。

Step S1360: at the first communication pattern, configure according to described antenna measurement, carry out descending CPR measures.The most descending CPR measuring unit only receives the pilot signal of first antenna (main antenna) and enters Row CPR measures, and RI is set to 1 by descending CPR measuring unit, and to carry out RI be 1 and antenna Measure broadband when being configured to 4TX/1RX or 2TX/1RX or 1TX/1RX and subband PMI and CQI Measure, enter step S1370.

Step S1370: at the first communication pattern, measurement result is reported to network side.If now CPR is to give the correct time, by the measurement result of CPR by PUCCH channel report network side (base in periodicity Stand)；If aperiodicity reports, wait the DCI(Downlink that network side PDCCH channel carries Control Information, Downlink Control Information) instruction, by measurement result and the Traffic Channel of CPR By PUSCH channel reporting base station after group bag, enter S1380.

In one implements, for reporting pattern aperiodic, base station is in descending PDCCH DCI Instruction wireless terminal reports PMI/CQI/RI(Channel Quality Indicator/Precoding Matrix Indicator/Rank Indicator, channel quality instruction/pre-coding matrix instruction/order indicates), above give the correct time Between determined by base station, in the test CASE of 3GPP, wireless terminal reports to base station every 1ms The measurement result of CPR, base station scheduling time delay is 10ms.

For periodically reporting pattern, base station is in advance and wireless terminal appoints report cycle, to the time Point wireless terminal reports PMI/CQI/RI.Giving the correct time on broadband, general CQI/PMI report cycle is 8 Frame=80ms(Frame, frame), RI report cycle is 4 × 8Frame=320ms；Extreme feelings Under condition, CQI/PMI report cycle is that 16Frame=160ms, RI report the time cycle to be 32 × 16 Frame=5.12s.So the PDSCH that wireless terminal typically can be obtained by base station new in 1s joins Putting, extreme case may have 5～6s.

Step S1380: adjust data transfer mode according to the information from network side.LTE physical layer connects Receiving unit and keep primary antenna configuration and physical layer control channel PCFICH/PDCCH, PBCH(physics is wide Broadcast channel) and PHICH(Physical Hybrid ARQ Indicator Channel, physical mixed is certainly Dynamic retransmission indicating chanel), the reception pattern of Traffic Channel PDSCH, wait that LTE base station is according to step CPR measurement result scheduling when the only use first antenna (main antenna) that S1370 reports receives adapts to The PDSCH transmission pattern of single antenna reception.

Specifically, LTE physical layer element obtains base station pair by the DCI information of decoding PDCCH channel The renewal configuration information of PDSCH, updates LTE physical layer after LTE physical layer control unit processes and connects Receive unit configuration, this configuration with wireless terminal LTE communication pattern use 1 reception antenna nothing Line transmission environment matches.

Step S1390: carry out data service under the first communication pattern.

Step S13100: initiate speech business or the concurrent industry of voice/data under the second communication pattern Business, simultaneously, enters S13110.

Step S13110: send the request of activating business under the first communication pattern, enter S13120.

Step S13120: receive and process RRC connection release message at the first communication pattern, enters S13130。

Step S13130: normal Standby under the first communication pattern.

Referring to Figure 14, wireless terminal is in the PS connection status of LTE communication pattern and descending biography In the case of defeated pattern is space division multiplexing mode, the circuit domain business initiating 2G/3G communication pattern (includes Caller and called) handling process include:

Step S1410: the second communication pattern initiates voice caller or called service request；

Step S1420: judge whether to keep the first communication pattern data service, as kept, then enters Step S1430；Otherwise, step S1490 is entered；

Step S1430: send the request of activating business under the first communication pattern, to network initiated data Business keeps request, and network configuration base station (eNodeB, evolved base station) is by downlink data transmission side Formula is revised as non-space division multiplexing from space division multiplexing, enters step S1440；

Step S1440: under the first communication pattern, terminal receives downlink signaling instruction transmission means and changes After becoming non-space division multiplex mode, enter step S1450；

Step S1450: the second antenna is switched to the second communication pattern, is that the second communication pattern is special With, enter step S1460；

Step S1460: initiate speech business at the second communication pattern, simultaneously, enter step S1470；

Step S1470: under the first communication pattern, carries out descending CPR measurement, reports and according to network Side information adjusts data transfer mode, and concrete steps are with step S1350 in Figure 13～step S1380；

Step S1480: carry out data service under the first communication pattern；

Step S1490: send the request of activating business under the first communication pattern, initiate voice to network Business falls request after rise；

Step S14100: receive at the first communication pattern and process RRC connection release message；

Step S14120: the second antenna is switched to the second communication pattern；

Step S14130: initiate speech business or the concurrent industry of voice/data under the second communication pattern Business.

Refer to Figure 15, communicate with second mould for more preferably realizing under above-mentioned first communication pattern data service Under formula, speech business is concurrent, and terminal this terminal of report network side when starting to register has extension CSFB energy Power, network side is required to support the process of extension CSFB related procedure.Specifically:

After the start of step S1510:UE, report network UE has extension CSFB ability, i.e. supports the Data service and speech business concurrent under the second communication pattern under one communication pattern.Concrete message can be Attach Request message (Attach Request) or tracing section updating message (TAU), enter step S1520。

Step S1520:UE initiates circuit domain dropping business, enters step S1530.

It will be understood to those skilled in the art that wireless terminal needs to carry out 2G/3G location area updating Scene includes but not limited to: carry out periodical location area renewal；Or wireless terminal reception system message is sent out Existing current area Location Area Identification changes.

Step S1620: judge whether the second communication pattern lane place changes, if it is, enter Enter step S1630, otherwise, return step S1610.

Step S1630, UE initiates " Combined TA/LA Update " under the first communication pattern Complete the second communication pattern location area updating.

Figure 17 is the embodiment under extension CSFB pattern, and this embodiment needs current network side to increase Corresponding function, to support that single UE carries out business, with current standard CSFB under two kinds of RAT simultaneously Flow process is compared owing to the second antenna is switched to the second communication pattern at once, so carrying out at the first communication pattern While CSFB signaling process, the second communication pattern starting position district updates and sets up CS business, adds Fast CSFB flow process speed, specifically includes:

When carrying out the second communication pattern location area updating, there is no a CS service request simultaneously:

The step of step S1610 of step S1710 and Figure 16 and step S1740 and Figure 16 S1630 is identical, repeats no more here.

In step S1720, it is judged that whether the second communication pattern lane place changes, if it is, Then enter step S1730, if it is not, then return S1710.

In step S1730, it is judged that the second communication pattern initiates CS business the most simultaneously, if it is, I.e. receive CS service request as location area updating simultaneously, then enter step S1750, otherwise, enter Step S1740.

In step S1750, judge whether the first communication pattern is in PS connection status and transmission mode is MIMO space division multiplexing transmission means, if the first communication pattern is in PS connection status and transmission mode For space division multiplexing transmission means, then enter step S17100, otherwise parallel execution of steps S1760 and S1790。

Perform step S17100, under the first communication pattern, initiate " Combined TA/LA Update " complete the second communication pattern location area updating.

Perform step S17110, under the first communication pattern PS connection status, initiate CSFB business, and Row performs S1760 to S1780 and S1790.

From step S1710 to S1780, the first communication pattern is in PS state, and the second communication pattern Prepare to initiate CS business, in order to reduce the turn-on time of the second communication pattern CS business, directly by the Two antennas are switched to the second communication pattern and carry out location area updating business, directly use the after location area updating CS business set up by two antennas.

In S1790, the first communication pattern is in PS state, uses single antenna to complete the first communication mould CS business falls signaling process after rise, carries out the CPR of descending single antenna reception under the first communication pattern simultaneously Measure, report and adjust the first communication pattern data transfer mode according to the information of network side.

Figure 18 is that under current CSFB pattern, LTE network occurs without covering or temporarily falling under net abnormal conditions Embodiment, owing to the LTE networking initial stage covers the best, the 2G/3G maturation network coverage is good, therefore exists LTE(the first communication pattern) fall to be switched to by the second antenna at once when netting (the second communication of 2G/3G network Pattern) carry out location area updating, notice network side radio terminal is changed into attachment by adhering to LTE network 2G/3G network, then wireless terminal is standby under the second communication pattern, and first antenna still provides for LTE (the first communication pattern) searches net, until LTE searches and nets successfully, then carries out associating tracking area (TA)/position Putting district (LA) renewal process, it is standby that wireless terminal returns to LTE network.At present scheme due to antenna without The method time-division, therefore LTE just can be switched to 2G/3G net after falling net after searching after a while and netting unsuccessfully Network, it is long to search the net time, cannot be carried out calling and called business, affect customer service and make during searching net With.After using new departure, LTE once falls net, and wireless terminal uses the second antenna to carry out 2G/3G at once Location area updating, uses first antenna to search net in LTE network simultaneously, has both ensured that user will not be at LTE Search off-grid during net, in turn ensure that wireless terminal can find LTE network the most again.

When wireless terminal is in CS or the CS/PS connection status of the second communication pattern, it is possible to realize first The cell measurement of communication pattern, system message update and TA update, in order to complete the second communication pattern The first communication pattern is quickly returned after CS business.CS or the CS/PS connection status of the second communication pattern Having only to an antenna and carry out uplink and downlink transmitting-receiving, the antenna that the first communication pattern utilizes another root idle is fixed Shi Jinhang cell measurement, system message receive and tracing section updating TAU(Tracking Area Update) Process.Under CS or the CS/PS connection status of the second communication pattern, LTE network is made TAU (Tracking Area Update) process needs current network side to increase corresponding function, single to support Individual UE carries out business under two kinds of RAT simultaneously.

Refer to Figure 19, under current CSFB agreement wireless terminal complete the second communication pattern CS or CS/PS business falls idle condition under the first communication pattern after rise.Detailed process is as follows:

After second communication pattern speech business or voice/data traffic terminate, by current CSFB agreement It is standby that the cell reselection of regulation or (Fast Return) mode that quickly returns return to the first communication pattern, Finally keep the holding state under the first communication pattern.

Refer to Figure 20, under extension CSFB agreement wireless terminal complete the second communication pattern CS or CS/PS business falls idle condition under the first communication pattern after rise, due to the second communication pattern CS or During CS/PS business, wireless terminal remains at the first communication pattern network holding state, runs into TAU process is just initiated in tracking area change, therefore need not do additionally after the second communication pattern terminates again The process of falling the first communication pattern.Detailed process is as follows:

During second communication pattern speech business or voice/data traffic knot, use first antenna the One communication pattern community realizes holding state.Run into the tracking area change of the first communication pattern, then use the One antenna initiates TAU process in the first communication pattern community, it is achieved the tracking area of the first communication pattern is more Newly.After the second communication pattern speech business or voice/data traffic terminate, configure the second antenna Between one communication unit port and the second communication unit port, time-division switching, then keeps under the first communication pattern Holding state.

Refer to Figure 21, under extension CSFB agreement wireless terminal complete the second communication pattern CS or CS/PS business falls connection status under the first communication pattern after rise, due to the second communication pattern CS or During CS/PS business, wireless terminal remains and keeps being connected, therefore with the first communication pattern network Only need to update CPR measurement pattern during falling and require that the first communication pattern network side is by single antenna reception Transmission mode is adjusted to two antennas and receives transmission mode.Detailed process is as follows:

After second communication pattern speech business or voice/data traffic terminate, configure the second antenna first Time-division switching between communication unit port and the second communication unit port, then configures the double sky of the first communication unit Line CPR measurement pattern, sends CPR report to the first communication pattern network side, single antenna reception passes Defeated mode adjustment is dual-antenna reception transmission mode, finally, keeps the connection shape under the first communication pattern State.
