Description
Technical field
The present invention relates to communication technical field, the control method of particularly a kind of communication terminal business execution and device.
Background technology
The continuous innovation of the cellular communications networks communication technology and evolution, cause multiple wireless access technology (RAT, Radio Access Technology) network and the phenomenon of depositing, cause supporting that the terminal (referred to as multimode terminal) of plurality of communication schemes becomes the mobile terminal of main flow.Usually a kind of communication pattern (or being called communication standard) of often kind of RAT counterpart terminal.In communication protocol, the measurement between different RAT, is also referred to as cross-system and measures.
At present, mobile terminal supports plurality of communication schemes usually, such as support the global system for mobile communications (GSM in the second generation (2G) communication system, Globe System of Mobile Communication), general packet radio service technology (GPRS, General Packet Radio Service), enhanced data rates for gsm evolution technology (EDGE, Enhanced Data Rate for GSM Evolution) while, also support the TD SDMA (TD-SCDMA in the third generation (3G) communication system, TimeDivision-Synchronous Code Division Multiple Access), Wideband Code Division Multiple Access (WCDMA) (WCDMA, Wideband Code Division Multiple Access), CDMA 2000 (CDMA2000, Code Division Multiple Access2000) one or more pattern, and Long Term Evolution (LTE can be supported further, Long Term Evolution) system.LTE is further divided into time-division LTE(TD-LTE) and LTE Frequency Division Duplexing (FDD) (LTE FDD) two kinds of duplex modes.The downlink peak rates of LTE may reach 300 MBPSs, and the theoretical downstream rate of evolution (LTE-A, LTE-Advanced) of LTE may reach 10 times of LTE.Compare 2G and 3G network, the speed of LTE network improves greatly.Undoubtedly, reside in LTE network as far as possible, be conducive to improving user to the impression of data service.
Speech business is realized in LTE network, there is the mode that three kinds main, circuit domain dropping (CSFB, CircuitSwitched Fallback), injection frequently continuous voice call (SRVCC, Single Radio Voice CallContinuity) and the general access of LTE voice (VoLGA, Voice over LTE Generic Access).When residing in LTE, if use speech business, CSFB scheme, terminal need fall back to 2G/3G network to be conversed; VoLGA scheme, by increasing a network element, A or the Iu interface of simulation 2G/3G, although terminal is still in LTE network, speech business is in fact completed by 2G/3G; SRVCC scheme, then directly provide IP-based voice, when terminal moves between LTE and 2G/3G, keep IP Multimedia System (IMS, IP Multimedia Subsystem) seamless switching between the voice based on IP agreement (VoIP, Voice overInternet Protocol) that control and circuit domain voice.Therefore, SRVCC and the voice (VoLTE, Voice over LTE) based on LTE together, constitute a complete LTE voice scheme.Namely in LTE network, use the VoIP speech business based on IMS, if desired leave network, then realized the seamless switching of LTE to 2G/3G by SRVCC.

Embodiment
The communication terminal of multi-card multi-standby single-pass in prior art, multiple subscriber cards are standby when same communication pattern, a business that subscriber card carries out can interrupt the business of other subscriber cards, common processing mode according to priority determines to perform the business of which subscriber card, and interrupted the subscriber card of business execution, after the service ending of other cards of high priority, can the data transmit-receive no matter in the corresponding wireless access technology of this card recover, all lost by the business datum interrupting period, thus impact by the business interrupting the subscriber card of execution, communication quality is reduced.Such as, subscriber card A is carrying out speech business, if at this moment need the paging receiving subscriber card B, then, during subscriber card B paging receiving, the speech business of subscriber card A there will be interruption; Otherwise communication terminal also can be implemented as the priority of priority higher than paging receiving of speech business, such subscriber card A when carrying out speech business, then can not receive the paging of subscriber card B, then subscriber card B may lose paging.
In a communications system, different business, its service quality (QoS, Quality of Service) is different.Different business, uses different quality of service class identifiers (QCI, QoS classidentifier) to identify, and each QCI has its each self-corresponding packet delay budget (PDB, PacketDelay Budge).Such as, the time delay budget of real-time game is 50 milliseconds, and the time delay budget of session voice, packet domain signaling, packet domain voice/video/game is 100 milliseconds, and conversational video is 150 milliseconds, and the budget of non-session class video, packet domain video is 300 milliseconds.So-called time delay budget is in most cases data contingent maximum transmitted time delay from transmit leg to recipient, or perhaps the acceptable maximum of propagation delay time that should as far as possible ensure during Communication System Design.And in real network, when communication environment is normal, the transmission of data all can be less than this budget time delay usually; When communication environment is poor, actual transmissions time delay then may exceed budget, and at this moment quality of service can decline.And download, upload class business, its time delay budget is then much larger.
Obviously, the requirement of different types of service to time delay is different.Such as, download class data service, tolerable time delay is very large; But voice class business, if time delay exceedes certain limit, then can bring the sharply decline of speech quality.
Therefore, for the subscriber card being suspended execution business, when the data transmit-receive in its corresponding wireless access technology is restored, can for the requirement of different service types to time delay, determine that corresponding data receive and dispatch strategy again, for the business that some requirement of real-times are higher, because it is higher to the requirement of time delay, then abandon again transmitting and receiving service perform be suspended and fail receive and dispatch data, and for the not too high business of some requirement of real-times, whether be then suspended by further analysis business the time delay that execution causes can make data again receive and dispatch the time delay budgetary request still meeting this type of service, again receive and dispatch the data be suspended, otherwise the transmitting-receiving again abandoned for the data be suspended.
Based on above-mentioned analysis, the control method that embodiment of the present invention provides a kind of communication terminal business to perform, the time delay that execution causes is suspended by the business of subscriber card, and different business is different to the requirement of time delay budget, determine after the business of certain subscriber card is interrupted, whether also need again to receive or send and interrupted the data that period needs to receive or send, alleviate the impact suffered by business be suspended, guarantee the continuity of business under requirement of real-time, improve communication quality.
As shown in Figure 1, the control method that the communication terminal business that technical solution of the present invention provides performs comprises:
Step S1, if exist overlapping between the time slot of Radio Resource corresponding to subscriber card, then select the time slot of the Radio Resource wherein corresponding to a subscriber card performs data transmitting and receiving service, and suspend the data transmit-receive business in the wireless access technology of execution corresponding to other subscriber cards;
Step S2, when the subscriber card that the business that is suspended performs recovers the data transmit-receive in its corresponding wireless access technology, the time delay budget being suspended time delay that execution causes and this type of service according to its business determines whether again to receive and dispatch the data be suspended, described in the data that are suspended refer to and perform because business is suspended and fails the data of receiving and dispatching.
It should be noted that, two subscriber cards at least supported by the communication terminal in embodiment of the present invention, wherein said subscriber card be for such as SIM card, usim card and other there is the general designation of the card of same or similar effect.
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail specific embodiments of the invention below in conjunction with accompanying drawing.
It should be noted that, for the communication terminal of dual-card dual-standby single-pass, the control method that described communication terminal business performs is described in the present embodiment, be understandable that, in other embodiments, described communication terminal also can be the communication terminal of other forms of multi-card multi-standby single-pass, and such as the communication terminal of single-pass treated by three cards three.
In addition, the communication terminal of the dual-card dual-standby single-pass in the present embodiment comprises single baseband chip, and in other embodiments, communication terminal can have two or more baseband chips completely.Such as, a baseband chip supports 2G/3G, and another one baseband chip supports LTE, even if or two baseband chips all support 2G/3G/LTE, but the radio frequency of LTE only has one, cannot support that multiple subscriber card performs LTE business simultaneously, so also go for technical scheme provided by the invention.
And, the control method that the communication terminal business that technical solution of the present invention provides performs also is not limited to the communication terminal being suitable for multi-card multi-standby single-pass, for the communication terminal that how logical some multi-card multi-standby is, if one of them signal path is supported, the subscriber card of more than is standby, and it is standby in the situation of same communication pattern likely to there are at least two subscriber cards, then the control method that described communication terminal business performs can be suitable for equally.
The standby residing communication pattern of subscriber card in the present embodiment both can be all the communication pattern of 2G/3G, communication pattern such as GSM, GPRS and EDGE etc. of 2G, communication pattern such as TD-SCDMA, WCDMA and CDMA2000 etc. of 3G, also can be all the communication pattern of LTE, can also be that a subscriber card is standby in the communication pattern of 2G/3G, another subscriber card be standby in the communication pattern of LTE.
Time delay budget, for different business, in communication protocol, such as 3GPP TS23.203, defines the packet delay budget corresponding to different QCI.Such as, but in communication protocol, the business operation that not communication terminal is all has all been defined time delay budget, and even some business operation does not have the concept of time delay budget, circuit domain business, signaling etc.
Therefore, in the present embodiment, define the business operation of some real-times, its corresponding time delay budget is set as 0 millisecond, and these business operations comprise: the signaling that receiving system broadcast, paging receiving, reception network issue, transmission signaling, circuit domain speech business.The signaling of the described signaling that issues or transmission, refers to the signaling of chain of command.Described chain of command defines to some extent in relevant communication protocol, is not described in detail herein.
It should be noted that, in the present embodiment, described data transmit-receive business, except comprising packet domain task, also comprises the broadcast of above-mentioned receiving system, paging receiving, the signaling receiving and transmission of chain of command and circuit domain speech business.
Fig. 2 is the structural representation of the communication terminal of the embodiment of the present invention.As shown in Figure 2, communication terminal comprises single baseband chip, and described baseband chip supports the connection of two SIM/USIM cards, and controls two radio frequencies (RF, Radio Frequency) interface and be connected with two RF.Two RF corresponding LTE and 2G/3G pattern respectively.Such as RF1 supports TD-SCDMA/GSM pattern, and RF2 supports LTE pattern; Or RF1 supports WCDMA/GSM pattern, RF2 supports LTE pattern.RF1 can support that the reason of 2G or 3G two patterns is simultaneously, and 2G and 3G network usually can not be simultaneously resident, that is communication terminal can not be simultaneously standby at 2G and 3G network.When two SIM/USIM draw-in grooves that baseband chip connects, be inserted into a SIM card respectively, during a usim card, SIM card can only be standby at 2G/3G network, and usim card then can be standby at LTE network or 2G/3G network.The general work principle dawn known to those skilled in the art of communication terminal shown in Fig. 2, introduce no longer in detail herein.
If two draw-in grooves all insert usim card, then may occur the combination of 3 kinds of standby modes, namely two subscriber cards are all standby in LTE pattern, or all standby in 2G/3G pattern, or a subscriber card is standby in LTE pattern, and another subscriber card is standby in 2G/3G pattern.
Above-mentioned 3 kinds of combinations, when two subscriber cards simultaneously standby at same mode time, then there will be the use scenes of dual-card dual-standby single-pass, namely wherein a subscriber card when call, another is standby in the subscriber card of model identical, likely cannot receive paging or perform other business.
And for the present embodiment, packet switch domain service can be utilized, the characteristic that grouped data can be retransmitted automatically, and different business is different to the requirement of packet delay budget, determine after the business of certain subscriber card is interrupted, whether also need to resend and interrupted the data that period needs to send or receive, and then the continuity of the business of guarantee under requirement of real-time.And for being interrupted period this subscriber card data that should receive, because terminal can not confirm to network by feedback reception, this part grouped data can be retransmitted according to its strategy automatically by network.This advantage, is especially embodied in one or more subscriber card under the scene performing packet switch domain service.Such as, subscriber card A carries out IP voice call in LTE pattern, by the paging of standby equally another subscriber card B in LTE pattern receive interrupt, then after subscriber card B paging receiving, according to by the delay interrupted, with the time delay budget of ip voice business, determine that subscriber card A is interrupted the ip voice packet of part the need of resending.Above-mentioned scene, when blocking under the 2G/3G pattern that works for two simultaneously, also can do similar process.
Fig. 3 illustrates the schematic flow sheet of the control method that the communication terminal business of the embodiment of the present invention performs.
First perform step S301, between the time slot judging Radio Resource corresponding to multiple subscriber cards, whether there is overlap.
During concrete enforcement, judge in the wireless access technology physical layer corresponding to the different user card that communication terminal is standby by step S301, between the time slot (or the other times cycle in units of time slot) of the Radio Resource distributed, whether there is overlap.
In the present embodiment, " multiple subscriber cards " in step S301 specifically refers to two SIM/USIM cards, a subscriber card can be called subscriber card A, another subscriber card is called subscriber card B.As for how judging in each self-corresponding wireless access technology physical layer of subscriber card A and subscriber card B, whether the time slot of the Radio Resource distributed exists overlap, and this is conventionally known to one of skill in the art, is not described in detail herein.
If judge to there is not overlap by step S301, then perform step S302, the business datum of subscriber card corresponding to the time slot of transmitting-receiving current radio resource.Particularly, on the time slot that namely step S302 judges in step S301, the business datum of subscriber card corresponding to this time slot is received and dispatched.
If judge to there is overlap by step S301, then perform step S303, select the business datum of receiving and dispatching a wherein subscriber card according to the business execution priority of different user card, and suspend the business datum transmitting-receiving of other subscriber cards.
Particularly, when gap is overlapping when present, need to select the corresponding time slot of the wireless access technology wherein corresponding to a subscriber card receives or sends signal, and the reception simultaneously suspended in other wireless access technologys corresponding to card or transmission.In the present embodiment, specifically select the highest subscriber card of the execution priority of corresponding data transmitting and receiving service to carry out data transmit-receive on the time slot of the Radio Resource of its correspondence, the execution priority of wherein said data transmit-receive business determines based on the time delay budget of this type of service.In general, the time delay budget of the corresponding type of service of described data transmit-receive business is less, then the execution priority of this data transmit-receive business is higher.
When the interface-free resources of the wireless access technology corresponding to multiple subscriber cards, when time slot occurs overlapping, according to the priority of the data transmit-receive business that multiple subscriber cards perform separately, determine perform the subscriber card of data transmitting and receiving service and be suspended the subscriber card of execution data transmitting and receiving service.The sequence of priority has multiple implementation, and different mode effects is different.Common order, is from high to low: the business of the transmitting-receiving of signaling, circuit domain voice, paging receiving, packet domain.The priority of different business in packet switch domain service, can determine according to its QCI.
In the present embodiment, if subscriber card A performs the downloading business in packet switch domain service in LTE pattern, period, standby equally another subscriber card B in LTE pattern needed paging receiving, so owing to performing the priority of the business of paging receiving higher than the priority performing packet switch domain service, then subscriber card A perform packet switch domain service in downloading business by interrupt by the business of the paging receiving of subscriber card B, select the paging of subscriber card B preferential receipt, and then carry out follow-up processing flow.
After step S303, perform step S304, judge, being suspended the time slot corresponding to the subscriber card of business datum transmitting-receiving, again receiving and dispatching the data be suspended and whether can meet time delay budget.
Particularly, when the subscriber card that the business that is suspended performs recovers the data transmit-receive in its corresponding wireless access technology, namely this be suspended subscriber card that business performs run into its not have with other subscriber cards corresponding to the time slot of Time Slot Overlap, although even if or Time Slot Overlap corresponding to the Radio Resource of described time slot and other subscriber cards, but when being selected as transmitting and receiving service data on the time slot of these overlaps by subscriber card, judge again to receive and dispatch the time delay the budgetary request whether data be suspended can meet current business.
If judge to meet time delay budgetary request by step S304, then perform step S305, again receive and dispatch the data be suspended, time delay budgetary request can not be met if judge, then perform step S306, abandon again receiving and dispatching the data be suspended.
When reality is implemented, step S304 ~ step S306, the time delay budget being specifically suspended time delay that execution causes and this type of service according to the subscriber card being suspended execution business because of business determines whether again to receive and dispatch the data be suspended, namely correspond to step S2, generally can be realized by following two kinds of modes:
The first implementation:
The data be suspended described in if the business of subscriber card is suspended time delay that execution causes and again receives and dispatches estimate the time delay budget that time delay sum is less than this type of service, the data be then again suspended described in transmitting-receiving, otherwise abandon the transmitting-receiving again to the described data be suspended.
Particularly, business is suspended to the subscriber card of execution, when running into it and there is no the time slot of the corresponding Time Slot Overlap with other cards, or when encountering overlapping time slot, but when this subscriber card be previously suspended is selected as the subscriber card preferentially performing the operation of data transmitting and receiving service, then according to the time delay budget of its operation be suspended, determine whether again to receive and dispatch the data be suspended.If need to resend the data be suspended, when estimate time delay and the business before this that calculate the data that are suspended and arrive receiving terminal are suspended the time delay budget that time delay sum that execution causes is less than this type of service, then show the time delay budget that substantially can meet corresponding business operation, the data be previously suspended can be retransmitted, otherwise abandon retransmitting.
Such as, for the business operation of real-time, its time delay budget is 0 millisecond, then can abandon again receiving and dispatching the data be suspended; And for the class business of uploading of packet domain, due to time delay budget almost not requirement, then the data be suspended usually again should be received and dispatched; And for other business of packet domain, its current time delay budget, then should by the time delay budget of defined in communication protocol, then the business that deducts is suspended caused time delay, and its result can be called residual time delay budget at this.When described residual time delay budget is less than 0 millisecond, or time delay when being less than business datum estimating from transmitting terminal to receiving terminal, then abandon retransmitting.
The second implementation:
If the business of subscriber card is suspended ratio that time delay that execution causes accounts for the time delay budget of this type of service when being less than predetermined threshold value, then the data be again suspended described in transmitting-receiving, otherwise abandons the transmitting-receiving again to the described data be suspended.
In the second implementation, the span of described predetermined threshold value is [1/10,1/2], such as, can value be 3/10.
When reality is implemented, in order to easy calculating, can judge that the business of subscriber card is suspended ratio that time delay that execution causes accounts for the time delay budget of this type of service and whether is less than certain value between 1/10 to 1/2, namely judge whether described residual time delay budget is still more than or equal to 0.5 to 0.9 times of time delay budget, if then show that there is enough time receives and dispatches the data be suspended again, otherwise abandon the transmitting-receiving again to the data be suspended.As for the design parameter value between 0.5 to 0.9 times, then can setting in communication terminal design realizes.General value is larger, larger by the probability abandoning again receiving and dispatching; Otherwise value is less, data are larger by the probability again received and dispatched, but the probability of the data that transmitting-receiving again also may be brought to cause blocking is also larger.
