It is default to match somebody with somebody in the case where the mode of operation of wireless terminal is set to CSFB patterns also referring to Fig. 7 and Fig. 9 It is set to the second antenna 122 and is connected to the second communication unit port 1313.

In the course of work of wireless terminal, switched second day according to the current communication mode of wireless terminal and type of service Coupling relation between line 122 and communication unit 110.

Specifically,

In step S910, the net resident stage is searched in start, the second antenna 122 of configuration is connected to the second communication unit port 1313；

In step S920, after being resident successfully, the first communication pattern (LTE communication pattern) and the second communication pattern (2G/3G Communication pattern) be in normal Standby state, terminal report network its there is CSFB abilities, i.e. terminal notification network it support tool There is the access capability in LTE network and 2G/3G networks.Here normal Standby refers to that cell system message can be normally received and wide Message, beep-page message are broadcast, meets normally resident (Normal Camping) condition of 3GPP agreements 25.304.Here terminal is reported There is LTE network CSFB ability idiographic flows to refer to the agreements of 3GPP 24.301；

Second communication pattern returns to holding state, into S930；

It will be understood to those skilled in the art that in above-mentioned embodiment, when LTE communication pattern and 2G/3G communications When pattern is all in IDLE state, LTE communication pattern and 2G/3G communication pattern time-divisions use diversity antenna, for receiving paging And measurement；When LTE communication pattern is in PS connection status and 2G/3G communication patterns are in IDLE state, LTE communication pattern is only Vertical to use primary antenna, diversity antenna is used by time division way for LTE communication pattern and 2G/3G；When LTE communication pattern is in PS Connection status or IDLE state, when 2G/3G communication patterns initiate CS (Circuit Switched Domain, circuit domain) business, LTE communication pattern is received and dispatched using only primary antenna, and diversity antenna is switched into 2G/3G communication patterns receives and dispatches for business.

For the processing in above-mentioned S930, Figure 10 is referred to, is comprised the following steps：

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

In step S1020, calculated respectively according to systematic parameter the first communication pattern paging receiving time and measurement opportunity, Second communication pattern corresponding measurement opportunity.Here systematic parameter refers to the survey in cell system message under correspondence communication pattern Measure parameter and PCH configuration, paging occasion configuration parameter；

In step S1040, the second antenna time-division between the first communication unit port and the second communication unit port is configured Switching.

Citing, provides the second communication pattern measurement timing parameters by taking GSM as an example.GSM, which is under IDLE state, to be needed to GSM BCCH (Broadcast Control Channel, BCCH) is received, GSM RSSI (Received Signal Strength Indicator, received signal strength indicator) measurement, initial BSIC (Base Station Identity Code, Base station identity code) differentiate, BSIC confirms again.Following interval reception scheme can be used according to GSM frame structure：For GSM BCCH Receive, rssi measurement, initial BSIC differentiate, BSIC confirms again, can use 240ms for the cycle, it is 6ms's that the time is received every time Scheme is received.

It will be understood to those skilled in the art that in above-mentioned embodiment, terminal report network has CSFB abilities, And preferentially reside in LTE network.Terminal is while resident LTE network in the present invention, additionally it is possible to reside in 2G/3G networks, Including measurement 2G/3G cells simultaneously synchronous, read system message, progress location area updating etc., therefore (wrapped when initiating circuit domain call Include caller and called) in the case of, compared with existing CSFB flows (as shown in Figure 11 A), it can avoid to the same of 2G/3G cells Step, measurement, read system message and possible location area updating flow, therefore, it is possible to reduce calling establishment time delay.Treated in LTE Under machine pattern, the flow of circuit domain call is initiated referring to accompanying drawing 11B：

Step S1110：Wireless terminal (also referred to as user terminal User Equipment (UE) or mobile station Mobile Station (MS)) request (Extend Service Requet) message of activating business is sent to network, request CS business falls after rise；

Step S1120：Receive and handle RRC (Radio Resource Control, radio resource control) connections Discharge (RRC Connection Release) message；

Step S1130：The 2G/3G cell informations safeguarded according to UE initiate CS call setups in 2G/3G networks；

In above-mentioned steps S1130, existing protocol is speed call Establishing process, may in RRC connection release message Comprising message is redirected, include the cell system message such as frequency of 2G/3G Target cells.UE is without the information in the present invention, Directly calling is initiated using the UE 2G/3G cells safeguarded.

Another embodiment, due to terminal of the present invention can under two kinds of communication patterns of LTE and 2G/3G it is standby, therefore Under LTE standby modes, initiate to ignore above-mentioned S1110 and S1120 during circuit domain call, directly initiate to call by S1130, realize Audio call is faster initiated, while ensureing that LTE is in normal Standby state.

In for the application scenarios for example shown in Fig. 9, inventor further researches and develops discovery, similar S950 antenna combination Signal transmission quality problem may be brought with the coupling relation adjustment process of communication unit.

In detail, because LTE communication pattern uses two antennas in PS connection status, wireless terminal initiates 2G/3G's Need the diversity reception antenna of LTE system being switched to 2G/3G systems completely during CS business, the now reception of LTE communication pattern It is changed into 1 antenna from 2 antennas, following some influences occurs for communication quality：

For PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel), PCFICH Control channels such as (Physical Control Format Indicator Channel, Physical Control Format Indicator Channel) and Speech, when occurring 2G/3G CS business, the physical layer of wireless terminal can adjust the reception of control channel according to order, due to Control channel uses transmitting diversity, and reception antenna is changed into after one, antenna reception scheme by 4TX/2RX or 2TX/2RX or 1TX/2RX becomes 4TX/1RX or 2TX/1RX or 1TX/1RX (TX refers to network-side transmission, and RX refers to terminal reception), simply receives Diversity gain is without SNR (Signal to Noise Ratio, signal to noise ratio) is had under 3dB or so according to multi-path environment Drop, but the receptivity redundancy of control signal is larger, so SNR, which declines, receives influence on control channel less；

For PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) MIMO (Multiple-Input Multiple-Output have more and entered more) space division multiplexing transmission, is changed into 1 day from receiving 2 antennas and receiving Line causes two data blocks (TB) of PDSCH channels to be disturbed each other after receiving, and a large amount of error codes occurs；For other PDSCH letters For the transmission mode in road, reception antenna is changed into after 1 without diversity gain is received from 2, and SNR has according to multi-path environment 3dB or so decline, because LTE base station still keeps the data that the code modulation mode of former PDSCH channels is sent to terminal, therefore Error code also occurs in PDSCH channels.

For above-mentioned transmission quality problem, inventor passes through creative work, proposes a kind of new processing mode.Specifically Ground, when LTE communication pattern is in PS connection status, wireless terminal initiates 2G/3G CS calling services, sound if necessary to parallel When answering CS called services or doing CS domains location area updating, reception diversity antenna is stopped using under LTE communication pattern, its is complete 2G/3G communication patterns are switched to as sending and receiving antenna.By certain processing procedure so that LTE network side is by LTE system PDSCH channels are the transmission under adaptation single antenna reception by the transmission mode Dispatching adjustment under reception diversity or space division multiplexing channel Pattern.

It is illustrated below by the embodiment processing mode new to this.

Figure 12 is referred to, is a kind of structural representation of wireless terminal.

Wireless terminal includes：Upper unit 1201, LTE physical layer elements 1202 and antenna switching unit 130.The LTE Physical layer element 1201 includes LTE physical layers control unit 12021, LTE descending CPR (CQI/PMI/RI, Channel Quality Indicator/Precoding Matrix Indicator/Rank Indicator, channel quality is indicated/prelisted Code matrix instruction/order instruction) measuring unit 12022, LTE physical layers receiving unit 12023.

Wherein, the LTE physical layers control unit 12021 is used to receive the switching of the antenna from upper unit 1201 During instruction, the antenna measurement configuration of the modification descending CPR measuring units 12022 of LTE；Receiving the configuration of the renewal from network side After information, control the LTE physical layers receiving unit 12023 to update and receive configuration；

The descending CPR measuring units 12022 of LTE are used to carry out in CPR measurements, generation under antenna measurement configuration Offer the measurement result of network side；

The LTE physical layers receiving unit 12023 is used to be received from network side according to the reception configuration of the renewal Signal；

The upper unit 1201 is used in the case where the LTE physical layers receiving unit 12023 updates and receives configuration, Antenna switching unit 130 is controlled to carry out the switching of antenna links scenarios.

Wireless terminal is in initiation CSFB operation flows under the PS connection status of LTE communication pattern and is divided into space division multiplexing and non- Two kinds of situations of space division multiplexing.Here space division multiplexing refers to logical multi-input multi-output, using fading characteristic between different antennae not Related the characteristics of space division multiplexing transmission multichannel data.In LTE, space division multiplexing is realized by 2X2 MIMO and 4X2 MIMO, i.e., The hair of antenna 22 is received or 4 hairs 2 are received, and by space division multiplexing transmission two paths of data on a carrier wave, the PDSCH in LTE passes through MIMO Realizing the transmission mode of two-way TB data space division multiplexings has 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 spatial division multiplexings With transmission, received from 2 antennas and be changed into causing two TB data blocks of PDSCH channels to be disturbed each other after 1 antenna is received, occurred big Measure error code；

Here non-space division multiplexing refers to the TM1 in PDSCH only transmission of one line TB data blocks, LTE, TM2, TM3 single layers (Layer), TM4 single Layer and TM7 belong to non-space division multiplexing transmission pattern.For non-space division multiplexing PDSCH channels For transmission mode, reception antenna is changed into after 1 without diversity gain is received from 2, and SNR has 3dB according to multi-path environment The decline of left and right, because LTE base station still keeps the data that the code modulation mode of former PDSCH channels is sent to terminal, therefore Error code also occurs in PDSCH channels, but (Hybrid Automatic Repeat Request, mixing is certainly due to physical layer HARQ Dynamic repeat requests) merging is retransmitted, do not result in frequently RLC (Radio Link Control, wireless spread-spectrum technology) layer re-transmission Cause link step-out.

Figure 13 is referred to, the PS connection status and downlink transfer pattern that wireless terminal is in LTE communication pattern are non-NULL In the case of point multiplex mode, initiating the handling process of the circuit domain business (including caller and called) of 2G/3G communication patterns includes：

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

Step S1320：Second antenna is switched into the second communication pattern, is that the second communication pattern is special.

Step S1360：In the first communication pattern, configured according to the antenna measurement, carry out descending CPR measurements.It is i.e. descending The pilot signal that CPR measuring units only receive first antenna (primary antenna) carries out CPR measurements, and descending CPR measuring units set RI Be set to 1, and carry out RI for 1 and antenna measurement be configured to 4TX/1RX or 2TX/1RX or 1TX/1RX when broadband and subband PMI Measured with CQI, into step S1370.

Step S1370：In the first communication pattern, measurement result is reported into network side.If now CPR is in periodicity Give the correct time, by CPR measurement result by PUCCH channel report networks side (base station)；If aperiodicity is reported, network side is waited DCI (Downlink Control Information, the Downlink Control Information) instructions that PDCCH channels are carried, by CPR measurement As a result with after Traffic Channel group bag by PUSCH channel reporting base stations, into S1380.

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

Pattern is reported for periodicity, report cycle is appointed in base station with wireless terminal in advance, to time point wireless terminal Report PMI/CQI/RI.Given the correct time on broadband, general CQI/PMI report cycles are 8Frame=80ms (Frame, frame), and RI is reported Cycle is 4 × 8Frame=320ms；CQI/PMI report cycles are to be called time on 16 Frame=160ms, RI under extreme case Cycle is 32 × 16 Frame=5.12s.So wireless terminal typically can be obtained by the new PDSCH configurations in base station in 1s, Extreme case may have 5~6s.

Step S1380：Data transfer mode is adjusted according to the information from network side.LTE physical layers receiving unit is kept Primary antenna is configured and physical layer control channel PCFICH/PDCCH, PBCH (Physical Broadcast Channel) and PHICH (Physical Hybrid ARQ Indicator Channel, physical mixed automatic re-transmission indicating channel), Traffic Channel PDSCH reception mould Formula, the CPR measurement results being used only when first antenna (primary antenna) is received for waiting LTE base station to be reported according to step S1370 are adjusted Degree adapts to the PDSCH transmission pattern of single antenna reception.

Specifically, LTE physical layer elements obtain renewal of the base station to PDSCH by decoding the DCI information of PDCCH channels and matched somebody with somebody Confidence cease, through LTE physical layers control unit handle after update LTE physical layer receiving units configuration, the configuration with wireless end End is matched in LTE communication pattern using the wireless transmission environments of 1 reception antenna.

Step S1390：Data service is carried out under the first communication pattern.

Step S13110：Request of activating business is sent under the first communication pattern, into S13120.

Step S13120：Received in the first communication pattern and handle RRC connection release message, into S13130.

Step S13130：The normal Standby under the first communication pattern.

Wireless terminal is in the CS connection status of 2G/3G communication patterns, and wireless terminal is received using idle first antenna (Tracking Area Update, tracking area is more by the PS areas paging service of LTE communication pattern and ps domain calling and called business and TAU Newly) process, the embodiment needs current network side increase corresponding function, to support single UE simultaneously in two kinds of RAT (Radio Access Technology, wireless access technology) under carry out business.

Two embodiments of Figure 16 and Figure 17 are referred to, when wireless terminal is in LTE communication pattern, 2G/3G communication moulds are realized The handling process of the location area updating of formula.

Figure 16 is the embodiment under current CSFB patterns, because the second antenna timesharing is examined for the second communication pattern position area Survey, it is found that change updates 2G/3G by combining tracking area/location area updating (Combined TA/LA Update) flow immediately LAI (Location Area Identity, position area identification code), therefore when occur CSFB when need not carry out 2G/3G again Location area updating, is specifically included：

Step S1610：UE carries out the survey of the second communication pattern cell by time-division switch diversity antenna under first communication pattern Amount, terminal needs to carry out the second communication pattern location area updating.

It will be understood to those skilled in the art that wireless terminal need carry out 2G/3G location area updatings scene include but It is not limited to：Carry out periodical location area renewal；Or wireless terminal reception system message finds current area Location Area Identification hair Changing.

Step S1620：Judge whether the second communication pattern position area changes, if it is, into step S1630, Otherwise, return to step S1610.

Step S1630, UE initiate " Combined TA/LA Update " completions the second communication mould under the first communication pattern Formula location area updating.

Figure 17 is to extend the embodiment under CSFB patterns, and the embodiment needs current network side increase corresponding function, with Single UE is supported while carrying out business under two kinds of RAT, because the second antenna switches at once compared with current standard CSFB flows To the second communication pattern, so while the first communication pattern carries out CSFB signaling processes, the second communication pattern starting position Area updates and set up CS business, accelerates CSFB flow speed, specifically includes：

When carrying out the second communication pattern location area updating, while there is no CS service requests：

Step S1710 is identical with Figure 16 step S1630 with Figure 16 step S1610 and step S1740, here no longer Repeat.

In step S1720, judge whether the second communication pattern position area changes, if it is, into step S1730, if it is not, then returning to S1710.

In step S1730, judge the second communication pattern whether while CS business is initiated, if it is, i.e. as position area Update and receive CS service requests simultaneously, then into step S1750, otherwise, into step S1740.

Judge whether the first communication pattern is in PS connection status and transmission mode is MIMO spatial division multiplexing in step S1750 With transmission means, if the first communication pattern is in PS connection status and transmission mode is space division multiplexing transmission mode, enter Step S17100, otherwise parallel execution of steps S1760 and S1790.

Step S17100 is performed, " Combined TA/LA Update " complete second and led to for initiation under the first communication pattern Believe that mode position area updates.

Perform and CSFB business is initiated under step S17110, the first communication pattern PS connection status, it is parallel to perform S1760 extremely S1780 and S1790.

From step S1760 to S1780, the first communication pattern is in PS states, and the second communication pattern prepares to initiate CS industry Business, in order to reduce the turn-on time of the second communication pattern CS business, is directly switched to the second communication pattern by the second antenna and enters line position Directly the second antenna of use sets up CS business after putting area's more new business, location area updating.

In S1790, the first communication pattern is in PS states, and completing the first CS business for communicating mould using single antenna falls letter after rise Flow is made, while carrying out the CPR measurements of descending single antenna reception under the first communication pattern, is reported and according to the information of network side Adjust the first communication pattern data transfer mode.

Figure 18 is that the embodiment under net abnormal conditions occurs without covering or temporarily fallen in LTE network under current CSFB patterns, by Not good in LTE networking coverings at initial stage, the 2G/3G maturation network coverages are good, therefore at once will when LTE (the first communication pattern) falls to net Second antenna is switched to 2G/3G networks (the second communication pattern) and carries out location area updating, notifies network side radio terminal by adhering to LTE network is changed to adhere to 2G/3G networks, and then wireless terminal is standby under the second communication pattern, and first antenna still provides for LTE (the first communication pattern) searches net, is netted successfully until LTE is searched, then carries out joint tracking area (TA)/position area (LA) renewal process, nothing It is standby that line terminal returns to LTE network.Current scheme due to antenna can not the time-division, therefore LTE falls after net through searching net after a while 2G/3G networks can be just switched to after failure, it is long to search the net time, calling and called business can not be carried out during searching net, influence user Business is used.After new departure, LTE once falls net, and wireless terminal carries out 2G/3G positions area more using the second antenna at once Newly, while searching net in LTE network using first antenna, both ensured user will not during LTE searches net off-grid, in turn ensure that wireless Terminal can quickly find LTE network again.

When wireless terminal is in CS the or CS/PS connection status of the second communication pattern, the first communication pattern can be realized Cell measurement, system message update and TA update, quick after the CS business to complete the second communication pattern to return to the first communication Pattern.CS the or CS/PS connection status of second communication pattern only needs to an antenna and carries out uplink and downlink transmitting-receiving, the first communication mould Formula carries out cell measurement, system message using another idle antenna timing and received and tracing section updating TAU (Tracking Area Update) process.Under CS the or CS/PS connection status of the second communication pattern, make TAU (Tracking to LTE network Area Update) the current network side increase corresponding function of process needs, to support single UE to be carried out under two kinds of RAT simultaneously Business.

Refer to CS the or CS/PS business falling that wireless terminal under Figure 19, current CSFB agreements completes the second communication pattern Idle condition under first communication pattern.Detailed process is as follows：

After second communication pattern speech business or voice/data traffic terminate, pass through cell as defined in current CSFB agreements Gravity treatment or it is quick return to (Fast Return) mode to return to the first communication pattern standby, finally keep under the first communication pattern Holding state.
