Description

Multi-module radio terminal and its location area updating method

Technical field

The present invention relates to wireless communication field, particularly to multi-module radio terminal.

Background technology

Flourishing with various the Internet, applications, the existing third generation（3G, 3Generation）Communication network is The growing demand of people can not be met.Wireless communication system increasingly present mobile, broadband and interconnection networking send out Exhibition trend, under this situation, as forth generation（4G, 4Generation）The LTE of the communication technology（Long Term Evolution, i.e. 3GPP（Third generation partner program）Long Term Evolution project）Become following direction of network evolution.

LTE network is based on full Internet protocol（IP, Internet Protocol）Framework, can only provide based on point Group domain（PS, Packet Switched）Ip voice（VoIP, Voice over IP）Business, because LTE network does not possess meeting The words calling of class business and Service control ability are it is therefore desirable to by the IP Multimedia System of core net（IMS, IP Multimedia Subsystem）The control function of session service to be provided.

The deployment of LTE network and IMS network is individual process progressively.At the LTE network networking initial stage, for guaranteeing speech business The continuity of ability, a kind of implementation is to adopt circuit domain dropping（CSFB, Circuit Switched FallBack）Transition Sound result scheme, general principle is that terminal resides in LTE network, first gravity treatment/switch to 2G/3G before audio call is set up, There is provided speech business by 2G/3G network, speech business again returns to LTE network after terminating, wherein, 2G is second generation mobile communication The abbreviation of technical specification.CSFB concrete scheme and handling process refer to 3GPP23.272,3GPP24.301 and 3GPP23.401 Etc. agreement.

Present inventor finds through research, and for the CSFB scheme of existing protocol standard definition, subject matter has：

（1）Audio call setup time is long.With respect to traditional 2G/3G audio call, in CSFB scheme, terminal falls after rise from LTE During to 2G/3G network, there is measurement to 2G/3G Target cell, synchronization and system message and extra process, or even the bag such as read Include location area updating（LU）Process, leading to calling to connect time delay increases by 1～4 second, and then leads to whole time of call established length very Extremely 10 seconds can be can exceed that, poor user experience.In addition, call set-up time increases, also there is the wind of call setup success rate reduction Danger；

（2）The LTE time is returned long after end of conversation.Speech business, after 2G/3G network terminates, is returned by reselection modes , there is the second level unreachable time in LTE network, terminal cannot be carried out communication service, affects Consumer's Experience；

（3）If falling GSM after rise（Global System of Mobile Communication, global system for mobile communications）, Then voice-and-data business can not be concurrent.Currently most of 2G networks do not support double-transmission mode（DTM, Dual Transfer Mode）, after falling back to GSM, only speech business, it is impossible to support voice-and-data service concurrence, affects Consumer's Experience.For in State moves, and because 3G network overlay area is limited, therefore China Mobile a proposed projects is exactly that CSFB falls back to GSM net Network, by GSM network carry voice traffic；

（3）If falling GSM after rise, because voice-and-data business can not be concurrent, the calling and called business of PS all cannot be carried out.

In step S950, in the case that the second communication pattern initiates circuit domain business, configuration the second antenna 122 connects To the second communication unit port 1313, circuit domain business includes that voice caller, speech business be called and location area updating etc. here. Second communication pattern returns to holding state, enters S930；

It will be understood to those skilled in the art that in above-mentioned specific embodiment, when LTE communication pattern and 2G/3G communication When pattern is all in IDLE state, LTE communication pattern and 2G/3G communication pattern time-division use diversity antenna, for receiving paging And measurement；When LTE communication pattern is in PS connection status and 2G/3G communication pattern is in IDLE state, LTE communication pattern is only Stand and use main antenna, diversity antenna passes through time division way and uses 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）During business, LTE communication pattern is only received and dispatched using main antenna, diversity antenna is switched to 2G/3G communication pattern and is used for business transmitting-receiving.

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

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

In step S1020, according to systematic parameter calculate respectively 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 corresponding communication pattern Amount parameter and PCH configuration, paging occasion configuration parameter；

It will be understood to those skilled in the art that in above-mentioned specific embodiment, terminal to report network has CSFB ability, And preferentially reside in LTE network.In the present invention terminal while resident LTE network additionally it is possible to reside in 2G/3G network, Including measurement 2G/3G cell and synchronization, read system message, carry out location area updating etc., therefore when initiation circuit domain call（Bag Include caller and called）In the case of, compared with existing CSFB flow process（As shown in Figure 11 A）, it can be avoided that same to 2G/3G cell Step, measurement, read system message and possible location area updating flow process, therefore, it is possible to reduce calling establishment time delay.Treat in LTE Under machine pattern, the flow process initiating circuit domain call is referring to accompanying drawing 11B：

Step S1110：Wireless terminal（Also referred to as user terminal User Equipment（UE）Or mobile station Mobile Station（MS））Send request of activating business to network（Extend Service Requet）Message, request CS business falls after rise；

Step S1120：Receive and process RRC（Radio Resource Control, radio resource control）Connect Release（RRC Connection Release）Message；

Step S1130：CS call setup is initiated in 2G/3G network according to the 2G/3G cell information that UE safeguards；

In above-mentioned steps S1130, existing protocol is speed call Establishing process, may in RRC connection release message Comprise to redirect message, including the cell system message such as frequency of 2G/3G Target cell.UE is without this information in the present invention, The 2G/3G cell that UE safeguards directly is used to initiate calling.

Another embodiment, because terminal of the present invention can be standby under two kinds of communication patterns of LTE and 2G/3G, therefore exists Under LTE standby mode, initiate to ignore above-mentioned S1110 and S1120 during circuit domain call, directly calling is initiated by S1130, realize Faster initiate audio call, ensure that LTE is in normal Standby state simultaneously.

For in the application scenarios for example shown in Fig. 9, inventor researches and develops discovery, the antenna combination of similar S950 further With communication unit couple relation adjustment process may bring signal transmission quality problem.

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

For PDCCH（Physical Downlink Control Channel, Physical Downlink Control Channel）、PCFICH （Physical Control Format Indicator Channel, Physical Control Format Indicator Channel）Etc. control channel Speech, when there is the CS business of 2G/3G, the physical layer of wireless terminal can adjust the reception of control channel according to order, due to Control channel adopts transmitting diversity, and reception antenna is changed into one afterwards, 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 and sends, and RX refers to terminal and receives）, simply receive Diversity gain is without SNR（Signal to Noise Ratio, signal to noise ratio）According to multi-path environment have 3dB about under Fall, but the receptivity redundancy of control signal is larger, so SNR declines receives impact less to control channel；

For PDSCH（Physical Downlink Shared Channel, Physical Downlink Shared Channel）MIMO （Multiple-Input Multiple-Output, has more and enters more）Space division multiplexing transmission, is changed into 1 day from receiving 2 antennas and receiving Line leads to two data blocks of PDSCH channel after receiving（TB）Disturb each other, a large amount of error codes occur；For other PDSCH letter For the transmission mode in road, reception antenna is changed into without receiving diversity gain after 1 from 2, and SNR has according to multi-path environment 3dB about decline, the data being sent to terminal due to the code modulation mode that LTE base station still keeps former PDSCH channel, therefore PDSCH channel also occurs error code.

For above-mentioned transmission quality problem, inventor, 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 service, sound if necessary to parallel When answering CS called service or doing CS domain location area updating, stop using reception diversity antenna under LTE communication pattern, it is complete It is switched to 2G/3G communication pattern as sending and receiving antenna.Through certain processing procedure so that LTE network side is by LTE system PDSCH channel is the transmission adapting under single antenna reception by the transmission mode Dispatching adjustment receiving under diversity or space division multiplexing channel Pattern.

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

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

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

Figure 17 is the embodiment under extension CSFB pattern, and this embodiment needs current network side to increase corresponding function, with Support that single UE carries out business under two kinds of RAT simultaneously, because the second antenna switches at once compared with current standard CSFB flow process To the second communication pattern, so while the first communication pattern carries out CSFB signaling process, the second communication pattern starting position Area updates and sets up CS business, accelerates CSFB flow process speed, specifically includes：

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

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

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

In step S1730, judge whether the second communication pattern initiates CS business simultaneously, if it is, i.e. as position area Update and receive CS service request simultaneously, then enter step S1750, otherwise, enter 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.

Execution step S17100, under the first communication pattern initiate " Combined TA/LA Update " complete second lead to Letter mode position area updates.

Execution step S17110, initiates CSFB business under the first communication pattern PS connection status, executed in parallel S1760 is extremely S1780 and S1790.

From step S1710 to S1780, the first communication pattern is in PS state, and the second communication pattern prepares to initiate CS industry Second antenna, in order to reduce the turn-on time of the second communication pattern CS business, is directly switched to the second communication pattern and enters line position by business Put area's more new business, after location area updating, directly set up CS business using the second antenna.

In S1790, the first communication pattern is in PS state, falls letter after rise using the CS business that single antenna completes the first communication mould Make flow process, carry out the CPR measurement of descending single antenna reception simultaneously under the first communication pattern, report and the information according to network side Adjust the first communication pattern data transfer mode.

Figure 18 is that under current CSFB pattern, LTE network occurs no covering or temporarily falls the embodiment under net abnormal conditions, by Cover not good in the LTE networking initial stage, the 2G/3G maturation network coverage is good, therefore in LTE（First communication pattern）Fall and at once will when netting Second antenna is switched to 2G/3G network（Second communication pattern）Carry out location area updating, notify network side radio terminal by adhering to LTE network is changed to adhere to 2G/3G network, and then wireless terminal is standby under the second communication pattern, and first antenna still provides for LTE （First communication pattern）Search net, net successfully until LTE searches, then carry out joint tracking area（TA）/ position area（LA）Renewal process, no It is standby that line terminal returns to LTE network.At present scheme due to antenna cannot the time-division, therefore LTE falls after net through searching net after a while Just 2G/3G network can be switched to after failure, it is long to search the net time, during searching net, cannot be carried out calling and called business, affect user Business uses.After new departure, LTE once falls net, and wireless terminal carries out 2G/3G position area more using the second antenna at once Newly, search net using first antenna in LTE network simultaneously, both ensured user will not during LTE searches net off-grid, in turn ensure that movement Platform quickly can find LTE network again.

When wireless terminal is in CS the or CS/PS connection status of the second communication pattern, it is capable of the first communication pattern Cell measurement, system message update and TA update, so that quick after completing the CS business of the second communication pattern return the first communication Pattern.CS the or CS/PS connection status of the 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 using another idle antenna timing, system message receives and tracing section updating TAU（Tracking Area Update）Process.Under CS the or CS/PS connection status of the second communication pattern, TAU is made to LTE network（Tracking Area Update）Process needs current network side to increase corresponding function, to support single UE to carry out under two kinds of RAT simultaneously Business.

Refer to Figure 19, under current CSFB agreement, wireless terminal completes CS the or CS/PS business falling of 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, the cell that specified by current CSFB agreement Gravity treatment or quick return（Fast Return）It is standby that mode returns to the first communication pattern, finally keeps under the first communication pattern Holding state.

Refer to Figure 20, under extension CSFB agreement, wireless terminal completes CS the or CS/PS business falling of the second communication pattern Idle condition under first communication pattern, because, during CS the or CS/PS business of the second communication pattern, wireless terminal remains In the first communication pattern network holding state, run into tracking area change and just initiate TAU process, therefore terminate in the second communication pattern Do not need afterwards to do the process of extra falling first communication pattern again.Detailed process is as follows：

During second communication pattern speech business or voice/data traffic knot, using first antenna in the first communication mould Formula cell realizes holding state.Run into the tracking area change of the first communication pattern, then using first antenna in the first communication pattern Cell initiates TAU process, realizes the tracing section updating of the first communication pattern.In the second communication pattern speech business or voice/number After service ending, the time-division switching between the first communication unit port and the second communication unit port of configuration the second antenna, then Keep the holding state under the first communication pattern.

Refer to Figure 21, under extension CSFB agreement, wireless terminal completes CS the or CS/PS business falling of the second communication pattern Connection status under first communication pattern, because, during CS the or CS/PS business of the second communication pattern, wireless terminal remains Keep being connected with the first communication pattern network, therefore rollback when only need to update CPR measurement pattern and require the first communication pattern net The transmission mode of single antenna reception is adjusted to two antennas and receives transmission mode by network side.Detailed process is as follows：

After second communication pattern speech business or voice/data traffic terminate, configuration the second antenna is in the first communication unit Port and the switching of the second communication unit port time-division, then configure the first communication unit double antenna CPR measurement pattern, logical to first Letter mode network side sends CPR report, is adjusted to dual-antenna reception transmission mode by single antenna reception transmission mode, finally, protects Hold the connection status under the first communication pattern.

In the present invention, alleged antenna combination is the combination of all antennas in each wireless terminal, and the first and second antenna sets are Subset in this antenna combination.
