Description
Technical field
The present invention relates to the communications field, particularly the dual-mode terminal technology in the communications field.
Background technology
Continuous development along with the communication technology, various types of wireless communication systems have appearred, as global system for mobile communications (Global System for Mobile communication, be called for short " GSM "), Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, be called for short " WCDMA "), TD SDMA (Time Division Synchronous Code Division Multiple Access, be called for short " TD-SCDMA "), micro-wave access to global intercommunication (Worldwide Interoperability for Microwave Access, be called for short " WiMAX "), Long Term Evolution (Long Term Evolution is called for short " LTE "), bluetooth, China Mobile multimedia broadcasting (China Mobile Multimedia Broadcasting is called for short " CMMB ") or the like.Wherein, the data transfer mode under the GSM network comprises wireless universal packet service (General Packet Radio Service is called for short " GPRS ") and Enhanced General Packet Radio Service (Enhanced GPRS is called for short " EGPRS ") etc.In TD-SCDMA and evolution standard thereof, the terminal data business can use multiple mode to transmit, dedicated channel (DCH) for example, high speed downlink packet inserts (HSDPA, in 3GPP release 5 and CCSA communication industry standard second edition, define), high speed uplink packet inserts (HSUPA defines) or the like in the 3GPP release 7 and the CCSA communication industry standard third edition.
At present, many terminals (as mobile phone) all can be supported two kinds of wireless systems (or wireless standard), as not only supporting GSM but also support TD-SCDMA, or not only support GSM but also support WCDMA.The terminal of two kinds of wireless systems of this support is commonly referred to dual-mode terminal.Support that about portable terminal the technical scheme of multiple wireless system can be 11136547 United States Patent (USP) referring to the patent No..
In China's existing communication industry standard " specification requirement of TD-SCDMA/GSM (GPRS) dual-mode single-standby digital mobile communication terminal ", gravity treatment and the changing method of TD-SCDMA/GSM dual-mode terminal between TD-SCDMA and GSM network done clear and definite regulation.
Such as, when the TD-SCDMA/GSM dual-mode terminal is in the GSM network system, if the TD-SCDMA neighboring area signal intensity of measuring is Rtd-scdma, the value of Rtd-scdma is greater than TDD_Qoffset (the absolute door limit value of gravity treatment judgement between system within a certain period of time, this value is handed down to terminal in the broadcast of GSM sub-district, can dispose by operator) time, dual-mode terminal will be carried out the gravity treatment from the GSM sub-district to the TD-SCDMA sub-district.
When the TD-SCDMA/GSM dual-mode terminal was in the TD-SCDMA network system, the TD-SCDMA pattern defined among 3GPP standard TS 25.304 to the switching condition of GPRS pattern (promptly from the TD-SCDMA network system to the GSM network system), and basic procedure is as follows:
(1) dual-mode terminal resides in the TD-SCDMA sub-district, the sub-district that satisfies condition is initiated the measurement of signal strength signal intensity.For the TD-SCDMA sub-district, measuring amount is Primary Common Control Physical Channel (Primary Common Control Physical Channel is called for short " P-CCPCH ") received signal code power (Received Signal Code Power is called for short " RSCP "); For the GSM sub-district, measuring amount is received signal field intensity indication (Receiving Signal Strength Indicator is called for short " RSSI ").
(2) according to the network system parameter each cell signal strength that measures is adjusted after, adjusted each cell signal strength is carried out descending ordering.Particularly, the signal strength signal intensity Rs=Q after the process network system parameter adjustment of persistent district
Meas, s+ Qhyst
sSignal strength signal intensity Rn=Q after the process network system parameter adjustment of other sub-districts
Meas, n-Qoffset
S, nWherein, Q

Meas, nBe the nearby region measurement amount.Qhyst
sBe cell reselection parameters, obtain, be used to calculate Rs, the hysteresis of expression received signal quality by system message.PCCPCH RSCP (for the TD-SCDMA sub-district)/RSSI (for the GSM sub-district) is operation parameter Qhyst1 then
sQoffset
S, nWhen the gravity treatment of sub-district, obtain by system message, be used to calculate Rn, the difference of expression Serving cell and adjacent cell signal quality, PCCPCH RSCP (for the TD-SCDMA sub-district)/RSSI (for the GSM sub-district) is operation parameter Qoffset1 then
S, nBehind the Rn of the Rs that calculates persistent district and other sub-districts, descending Rs and each Rn are sorted.
(3) if find the better sub-district of signal quality, promptly come the sub-district of current service cell front, at a period of time Treselections (is the sub-district gravity treatment triggered time, obtain by system message, all be better than current area in the span 0～31s), and dual-mode terminal resides in current area and surpasses (1s) (being sub-district gravity treatment Penalty time), then selects best sub-district and resides in this sub-district.
This shows that in the prior art, when carrying out data service, dual-mode terminal is to reside in the GSM network or be the TD-SCDMA network, the signal strength signal intensity by both determines fully.
Yet, the present inventor finds, according to existing processing method, the GSM/TD-SCDMA dual-mode terminal is when carrying out data service, will select the network that signal is stronger among GSM and the TD-SCDMA to carry out transfer of data, but because the transmission rate that TD-SCDMA can support is far longer than GSM, it is stronger the GSM network signal to occur, but actual transfer rate is lower than the situation of TD-SCDMA network on the contrary.Such as when the signal strength signal intensity that is lower than gravity treatment thresholding that system provides and TD-SCDMA itself when the difference of GSM and TD-SCDMA signal strength signal intensity failed to reach absolute door limit value TDD_Qoffset, dual-mode terminal will reside in the GSM network and carry out data service.But in fact, because modulation and coded system is different, the message transmission rate of GSM and TD-SCDMA has bigger difference, following behavior example, the higher EGPRS of transmission rate is under the situation of class 12 (4 descending time slots) under the GSM pattern, and limit transmission rate is less than the 240K bits per second; And TD-SCDMA is HSDPAcategory 15 times, and transmission rate can reach the 2.8M bits per second, differs more than 10 times.Like this, though the TD-SCDMA network signal a little less than, even exist under the situation of a small amount of error of transmission, actual transfer rate still may be higher than the GSM network.Reside in gsm system under this scene, will cause the transmission rate of data service to reduce, thereby influence terminal use's use experience.
Summary of the invention
The object of the present invention is to provide a kind of data business transmission method and dual-mode terminal of dual-mode terminal, do not increasing cost, existing dual-mode terminal is not carried out making business datum to transmit with higher transmission rate under the situation of hardware change, improve user's impression.
For solving the problems of the technologies described above, embodiments of the present invention provide a kind of data business transmission method of dual-mode terminal, first network system of dual-mode terminal support belongs to 3-G (Generation Three mobile communication system), second network system of dual-mode terminal support belongs to second generation mobile communication system, comprises following steps:
Dual-mode terminal is after setting up data service, and is preferential resident in first network system;
In the process of transmitting data service, dual-mode terminal detects the transmission channel quality in first network system, and according to detected transmission channel quality, the actual transfer rate of calculated data business under first network system, if the actual transfer rate of data service under first network system, more than or equal to the maximum, theoretical transmission rate of data service under second network system, then dual-mode terminal continues to reside in first network system.
Embodiments of the present invention also provide a kind of dual-mode terminal, and first network system of dual-mode terminal support belongs to 3-G (Generation Three mobile communication system), and second network system of dual-mode terminal support belongs to second generation mobile communication system, and dual-mode terminal comprises:
Resident module is used for after setting up data service, and is preferential resident in first network system;

Embodiment of the present invention compared with prior art, the main distinction and effect thereof are:
When data service is initial, preferentially reside in the first higher network system of transmission rate, in the process of transmitting data service, according to the transmission channel quality in detected first network system, the actual transfer rate of calculated data business under first network system, if actual transfer rate is more than or equal to the maximum, theoretical transmission rate of data service under described second network system, then continue to reside in first network system, even the signal strength signal intensity of first network system and second network system has satisfied switching condition, can not switch yet.Owing to be not the complete resident network of signal strength signal intensity decision according to network system, but do not increasing cost, when existing terminal not being carried out the hardware change, utilize existing transfer of data situation as priori, channel quality to the first higher network system of transmission rate is assessed, and contrasting the theoretical speed of second network system, the network that selection can obtain maximum transmission rate carries out resident.Compare with existing method by signal strength signal intensity decision residing network, made full use of the transmission characteristic of dual-mode wireless network, more weak but still can satisfy under the environment of transmission conditions at the first higher network system signal of transmission rate, can obtain higher transmission rate, improve user's impression.And, interdepartmental system gravity treatment meeting brings extra current drain to terminal, and the present invention does not need to carry out frequent interdepartmental system reselection operation according to signal strength signal intensity under the situation that the speed of first network system meets the demands, effectively reduce power consumption of terminal, prolonged battery service time.
Further, reside in second network system if dual-mode terminal is current, then this dual-mode terminal need be waited for scheduled duration, and whether the judgment data business finishes after scheduled duration, if do not finish, then resident again in first network system, realize preferential resident step to described first network system.Because needing the data service of transmission may be the very little data service of deal with data amount, even under the second lower network system of transmission rate, also can finish very soon, if the therefore data service that in scheduled duration, just can finish, then need not again resident to first network system, switch because of triggering interdepartmental system avoiding, and bring unnecessary resource consumption.

Embodiment
In the following description, in order to make the reader understand the application better many ins and outs have been proposed.But, persons of ordinary skill in the art may appreciate that even without these ins and outs with based on the many variations and the modification of following each execution mode, also can realize each claim of the application technical scheme required for protection.
For making the purpose, technical solutions and advantages of the present invention clearer, embodiments of the present invention are described in further detail below in conjunction with accompanying drawing.
First embodiment of the invention relates to a kind of data business transmission method of dual-mode terminal.Fig. 1 is the schematic flow sheet of the data business transmission method of this dual-mode terminal.
In step 101, dual-mode terminal is set up data service.In the present embodiment, the network system that belongs to 3G of dual-mode terminal support is called first network system, just the network system that belongs to 2G of dual-mode terminal support is called second network system.Such as for the TD-SCDMA/GSM dual-mode terminal, the TD-SCDMA of dual-mode terminal support is first network system, and the GSM of support is second network system.
Then, in step 102, dual-mode terminal judges whether current resident wireless network is second network system.At above-mentioned case, the TD-SCDMA/GSM dual-mode terminal is judged current whether residing in the GSM network system, if reside in the GSM network system, then enters step 103; If do not reside in the GSM network system, promptly reside in the TD-SCDMA network system, then directly enter step 107.
In step 103, dual-mode terminal is waited for scheduled duration t, and whether the judgment data business finishes after scheduled duration.Wherein time t can be stipulated by dual-mode terminal oneself, also can be by network configuration.If the decision data business finishes behind the scheduled duration t, then enter step 104, dual-mode terminal returns holding state, process ends.Because needing the data service of transmission may be the very little data service of deal with data amount, even under the second lower network system of transmission rate, also can finish very soon, if the therefore data service that in scheduled duration, just can finish, then need not again resident to first network system, switch because of triggering interdepartmental system avoiding, and bring unnecessary resource consumption.If the decision data business does not finish as yet behind the scheduled duration t, then enter step 105.
In step 105, dual-mode terminal judges whether to exist the second available network system, if exist, then enters step 106, if there is no, then gets back to step 103.At above-mentioned case, the TD-SCDMA/GSM dual-mode terminal judges whether that available TD-SCDMA network exists, if there is available TD-SCDMA network, then enters step 106, if there is no available TD-SCDMA network then returns step 103 and recomputates the stand-by period.
In step 106, dual-mode terminal is resident in first network system, carries out data service in first network system.At above-mentioned case, the TD-SCDMA/GSM dual-mode terminal switches to the TD-SCDMA network system from the GSM network system, carries out data service in the TD-SCDMA network system.
Then, in step 107, dual-mode terminal detects the transmission channel quality in first network system, and according to detected transmission channel quality, the actual transfer rate of calculated data business under first network system.
Specifically, dual-mode terminal detects the transmission channel quality in first network system by detecting the transmission Block Error Rate (Block Error Rate is called for short " BLER ") of data service under first network system.Such as dual-mode terminal receives n bag data continuously, and the n here is a constant, provide by dual-mode terminal, can for 2 integral number power so that calculate.Packet with the physical layer of first network system at a delivery time (Transmission time interval at interval, abbreviation " TTI ") transmission block of handling in (Transport block) is that unit calculates, transmission block has cyclic redundancy check (CRC) (Cyclic redundancy check, be called for short " CRC ") result, can be used to judge whether this data block is correct.The quantity of crc error divided by total block data n, can be obtained dual-mode terminal transmission block error rate BLER during this period of time.
Then, obtain the transmission accuracy (be 1-BLER) of data service under first network system according to the transmission Block Error Rate, to multiply by the transmission accuracy in the maximum, theoretical transmission rate under first network system, obtain the actual transfer rate of data service under first network system.At above-mentioned case, the TD-SCDMA/GSM dual-mode terminal will multiply by the transmission accuracy that calculates from the maximum, theoretical transmission rate of supporting down in TD-SCDMA, obtain current actual transfer rate under TD-SCDMA.In the present embodiment, as the foundation of judging transmission channel quality, estimate that dual-mode terminal resides in the actual transfer rate under first network, realize simply, and can guarantee accuracy with the transmission Block Error Rate.
Then, in step 108, the actual transfer rate of dual-mode terminal judgment data business under first network system, whether more than or equal to the maximum, theoretical transmission rate of data service under second network system, if actual transfer rate is more than or equal to the maximum, theoretical transmission rate of data service under second network system, then continue to reside in first network system, directly enter step 110.If actual transfer rate then enters step 109 less than the maximum, theoretical transmission rate of data service under second network system.
At above-mentioned case, the TD-SCDMA/GSM dual-mode terminal will obtain, and current actual transfer rate and the maximum, theoretical transmission rate supported under the GSM network of dual-mode terminal under the TD-SCDMA network system compares, if in the actual transfer rate under the TD-SCDMA network system more than or equal to the maximum, theoretical transmission rate of data service under the GSM network system, then continue to reside in the TD-SCDMA network system, directly enter step 110.If in this step, the actual transfer rate under the judgement TD-SCDMA network system then enters step 109 less than the maximum, theoretical transmission rate of data service under the GSM network system.
In step 109, because the actual transfer rate of data service under first network system, less than the maximum, theoretical transmission rate of data service under second network system, therefore in this step, dual-mode terminal is according to the flow process of existing standard regulation, judge whether that according to signal strength signal intensity needs switch to second network system, whether the signal strength signal intensity of promptly judging first network system and second network system satisfies switching condition, if satisfy then enter step 111, to the network side reporting measurement reports, switching between triggering system, and after step 111, get back to step 103; If do not satisfy, then enter step 110.
At above-mentioned case, the TD-SCDMA/GSM dual-mode terminal judges whether the signal strength signal intensity of TD-SCDMA and GSM network satisfies the switching condition (specifically referring to the switching condition from the TD-SCDMA network system to the GSM network system in the background technology part) that defines in the existing standard.If satisfy then enter step 111, to the network side reporting measurement reports, trigger from TD-SCDMA to the switching of GSM network and return step 103, wait for and assess the TD-SCDMA network environment again; If do not satisfy switching condition, then enter step 110 from the TD-SCDMA network system to the GSM network system.
In step 110, whether dual-mode terminal judgment data business finishes, if finish, then process ends if do not finish as yet, is then got back to step 107, continue to detect the transmission channel quality in first network system, the actual transfer rate of calculated data business under first network system.At above-mentioned case, whether TD-SCDMA/GSM dual-mode terminal judgment data business finishes, if finish, process ends then, if do not finish as yet, then get back to step 107, continue to detect the transmission channel quality of TD-SCDMA network system, the actual transfer rate of calculated data business under the TD-SCDMA network system.
Be not difficult to find, in the present embodiment, it is not the complete resident network of signal strength signal intensity decision according to network system, but do not increasing cost, when existing terminal not being carried out the hardware change, utilize existing transfer of data situation, the channel quality of the first higher network system of transmission rate is assessed as priori, and contrasting the theoretical speed of second network system, the network that selection can obtain maximum transmission rate carries out resident.Compare with existing method by signal strength signal intensity decision residing network, made full use of the transmission characteristic of dual-mode wireless network, more weak but still can satisfy under the environment of transmission conditions at the first higher network system signal of transmission rate, can obtain higher transmission rate, improve user's impression.And, interdepartmental system gravity treatment meeting brings extra current drain to terminal, and present embodiment does not need to carry out frequent interdepartmental system reselection operation according to signal strength signal intensity under the situation that the speed of first network system meets the demands, effectively reduce power consumption of terminal, prolonged battery service time.For the TD-SCDMA/GSM dual-mode terminal, because the GSM network can't concurrent speech business in Packet data service is used, and TD-SCDMA can, reside in TD-SCDMA and make and to carry out voice call when the user carries out data service, make the probability of in data service is carried out, losing incoming call also decrease.
