Description
Technical field
The present invention relates to the information interaction technology of mobile communication system, particularly a kind of mode mobile terminal and Universal Terrestrial Radio Access Network network (UTRAN) carry out information interactive method.
Background technology
Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) has obtained good development as one of 3G (Third Generation) Moblie technology (3G) mainstream standard of Chinese independent research in recent years, technology is day by day ripe, has reached the standard of independent networking.But the TD-SCDMA networking initial stage, be limited to factors such as technology, financial resources, material resources, inevitably exist network signal to cover incomplete shortcoming, thereby can cause the user in the voice call process, in the local time that the user is in that network signal does not cover or signal is more weak, cause the phenomenon of call drop easily, use the TD-SCDMA portable terminal to bring great inconvenience to the user.
At the present situation of TD-SCDMA network, best solution is when the TD-SCDMA network condition is bad, utilizes existing global system for mobile communications (GSM) network to converse.And TD-SCDMA portable terminal technology is in developing stage, can realize simultaneously that the protocol stack (dual-mode protocol stack) of two kinds of access modules also is in the starting stage, and inevitably there are some problems in the switching between the bimodulus.Therefore, before the dual-mode protocol stack maturation, the TD-SCDMA/GSM mode mobile terminal that dual-mode dual-standby occurred, in this type of mode mobile terminal, have two protocol stacks independent of each other simultaneously, correspond respectively to TD-SCDMA access module and GSM access module, can realize TD-SCDMA/GSM standby simultaneously, satisfy user's demand.
But, because double-mode double-standby mobile terminal is gathered around and is had plenty of two single mode agreement independent of each other stations, insert in the process of conversation with TD-SCDMA at portable terminal, can not detect the signal quality of neighboring GSM cell and fill in the radio network controller (TDRNC) that measurement report offers TD-SCDMA, so, UTRAN can't obtain required GSM cell information, can't carry out the switch decision of TD-SCDMA access technology, thereby just can't realize that also the voice between wireless access technology (RAT) switch to the GSM access technology.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of mode mobile terminal and Universal Terrestrial Radio Access Network network to carry out information interactive method, can realize that the voice from the TD-SCDMA access module to the GSM access module switch.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of mode mobile terminal and Universal Terrestrial Radio Access Network carry out information interactive method, this method comprises: when the double-mode double-standby mobile terminal of support TD-SCMDA and GSM inserts in the TD-SCMDA mode, carry expression and self whether can carry out the sign that TD-SCMDA switches to gsm wireless access technology RAT in channel capacity information, can network side be undertaken switching between RAT by this sign judgement;
In communication process, whether described network side active inquiry portable terminal can carry out RAT switches, and mobile terminal reporting represents self whether to carry out the sign that RAT switches.
In the such scheme, described sign is carried in the reserved field of capability information of user facility in the existing 3GPP standard.Further, the described sign of this method is carried in the 3GPP TDD 3.84Mcps technology in the physical channel ability information.
Based on such scheme, described sign is divided into two kinds of values, ident value one and ident value two, and the gsm protocol stack GSMPS of the described portable terminal of ident value one expression is in holding state, can carries out the RAT switching; The described portable terminal of ident value two expressions does not support described RAT to switch or the GSMPS of current mobile terminal is in non-holding state.
Based on such scheme, this method comprises further that also the Man Machine Interface MMI by described portable terminal obtains the step whether current GSMPS is in the state information of holding state.
Based on such scheme, this method is set up in the flow process in the Radio Resource control connection, the entrained ident value one that is designated; In communication process, when the GSMPS of portable terminal when holding state becomes non-symbol machine state, described portable terminal initiatively reporting ability information is given network side, and the GSMPS that carries the expression portable terminal in ability information is in the ident value two of non-holding state; When the GSMPS of portable terminal when non-holding state becomes holding state, described portable terminal initiatively reporting ability information is given network side, and the GSMPS that carries the expression portable terminal in ability information is in holding state, can carries out the ident value one that RAT switches.
Based on such scheme, this method is in communication process, in the time of whether can carrying out the RAT switching by network side active inquiry portable terminal, described mobile terminal reporting is represented self whether to carry out the sign that RAT switches and is specially: the GSMPS of portable terminal is current during for holding state, and the GSMPS that carries the expression portable terminal in reporting ability information is in holding state, can carries out the ident value one that RAT switches; The GSMPS of portable terminal is current when being non-holding state, in reporting ability information and be in the ident value two of non-holding state at the GSMPS that ability information is carried the expression portable terminal.
Whether the present invention utilizes the reserved field in the mobile terminal reporting ability information to identify this portable terminal can carry out the RAT switching, makes network side can know whether this portable terminal supports RAT to switch.Because the present invention does not need two independent single mode protocol stacks of portable terminal are done bigger change, thereby implementation method is simple; And, owing to the gsm protocol stack is not made amendment, therefore can under the situation that does not influence existing GSM network use, finally improve the stability of TD-SCDMA and GSM double-mode double-standby mobile terminal.

Embodiment
Among the following embodiment of the present invention, described portable terminal comprises TD-SCDMA and two kinds of patterns of GSM at least, and can select holding state by portable terminal man-machine interface (MMI).Wherein, described holding state comprises: TD-SCDMA singly treats, GSM singly treats or TD-SCDMA/GSM is two treats etc.
As shown in Figure 1, portable terminal comprises independently protocol stack of two of TD-SCDMA and GSM among this embodiment, and portable terminal can be selected holding state by man-machine interface (MMI).Holding state is obtained by MMI, and current TD-SCDMA network is unavailable, need carry out automatic access module when switching, and controls portable terminal by MMI and carries out automatic mode switch.
Among Fig. 1, TD-SCDMA protocol stack (TDPS) is linked into the movements control center (TDMSC) of TD-SCDMA by the radio network controller of TD-SCDMA, gsm protocol stack (GSMPS) is linked into the movements control center (GSMMSC) of GSM by the base station controller (BSC) of GSM, and mobile terminal side is responsible for obtaining and storing the state of each protocol stack by MMI.
Fig. 2 is Radio Resource control (RRC) connection building process of TD-SCDMA, mainly is divided into three steps: the first step, subscriber equipment (UE) send to connect to RNC sets up request message RRCCONNECTION REQUEST, and request is set up a RRC and connected; In second step, after RNC receives that connection is set up request and finished necessary resource allocation, send connection to UE and set up message RRCCONNECTION SETUP; At last, receive to connect at UE can send connection setup complete message RRC CONNECTION SETUP COMPLETE to RNC after setting up message, in this message, comprise the ability information of UE.
The present invention utilizes the reserved field in the capability information field that UE reports, and identifies this portable terminal to RNC and whether can carry out TD-SCDMA and switch to the RAT of GSM.The reserved field that is utilized is a defined field in the 3GPP standard criterion, among the present invention this identification field is called dual-mode dual-standby and identifies.The present invention is divided into ident value one and ident value two with this tag slot, ident value one this portable terminal of expression is the double-mode double-standby mobile terminal that comprises TD-SCDMA and gsm protocol stack, and the gsm protocol stack of this portable terminal is a holding state, can carry out the RAT switching of TD-SCDMA to GSM; Ident value two these portable terminals of expression are not that double-mode double-standby mobile terminal or this portable terminal current GSM protocol stack are non-holding state, can not carry out the RAT switching of TD-SCDMA to GSM.
In one embodiment, when portable terminal is in that TD-SCDMA/GSM is two to treat state, in the call setup chain process, TD-SCDMA protocol stack TDPS utilizes that the reserved field in the UE capability information field carries ident value one in the RRC CONNECTION SETUPCOMPLETE message, and expression can be carried out TD-SCDMA and switch to the RAT voice of GSM.
When portable terminal was in TD-SCDMA and singly treats state, in the call setup chain process, TDPS reported in the UE ability of RRC CONNECTION SETUP COMPLETE message and carries ident value two in the field, expression does not support TD-SCDMA to switch to the RAT voice of GSM.For with the existing system compatibility, if network side does not carry dual-mode dual-standby when sign in detecting the ability information of mobile terminal reporting, give tacit consent to this portable terminal and do not support TD-SCDMA to switch to the RAT voice of GSM, the processing method of following scheme is with similar herein.
Portable terminal is in communication process, the state of GSMPS might change, and at this moment portable terminal initiatively reports the state of GSMPS to RNC, and described state has only two kinds, be holding state and non-holding state, obtain the current state value and organize reporting message to report RNC by MMI.As shown in Figure 3, use TD-SCDMA to insert in the communication process at portable terminal, when portable terminal GSMPS state change incident takes place, obtain the state value of GSMPS eventually by MMI, and initiatively send UE ability information reporting message to TDRNC, when the state value of GSMPS was holding state, described dual-mode dual-standby ident value was an ident value one; When the state value of GSMPS was non-holding state, described dual-mode dual-standby ident value was an ident value two.
In addition, as shown in Figure 4, network side also can the active inquiry portable terminal the holding state of GSMPS, compare with the flow process of portable terminal active reporting ability information, difference mainly is: give the correct time on passive, network side need at first be initiated a capability query request message UE CAPABILITYENQUIRY, and portable terminal is obtained the state of current GSM PS and reported network side by MMI after receiving inquiry request message.Take the passive scheme that reports when inserting, not carry the dual-mode dual-standby sign, have only when the TD-SCDMA network condition is bad, whether can carry out RAT by the network side enquiry mobile terminal switches, if ident value is an ident value one in the ability information of mobile terminal reporting, represent that then this portable terminal can carry out the RAT voice switching of TD-SCDMA to GSM, network side just can carry out switch decision so; If ident value is an ident value two in the ability information of mobile terminal reporting, represent that then this portable terminal can not carry out the RAT voice switching of TD-SCDMA to GSM, then network side is not done any operation.
Among the present invention, can select the TDD physical channel capability field of 3.84Mcps in the physics channel capacity (Physical Channel Capability), be used to carry required dual-mode dual-standby sign, because this field is not used in existing TDRNC, and TDD 3.84Mcps technology does not also re-use in the future, this field belongs to the reserved field in the 3GPP standard definition, uses this field can not have influence on the performance of RNC, can certainly select other similar field.The message basic structure of described TDD physicalchannel capability field is as follows:
physicalChannelCapability
{
tddPhysChCapability//TDD?physical?channel?capability
{
DownlinkPhysChCapability // down physical channel ability
{
MaxTS-PerFrame 1, // dual-mode dual-standby sign
maxPhysChPerFrame?5，
minimumSF?sf16，
supportOfPDSCH?FALSE，
maxPhysChPerTS?5
}
uplinkPhysChCapability
{
maxTS-PerFrame?1，
maxPhysChPerTimeslot?ts2，
minimumSF?sf2，
supportOfPUSCH?FALSE
}
}
}
Among the present invention, with down physical channel capable field (downlinkPhysChCapability, in the 3G standard standard, be called DL-PhysChCapabilityTDD) in the maximum time slot MaxTS-PerFrame of every frame information element field value fill out and be ident value one, for example integer value 1, represent that this UE is the TD-SCMDA/GSM double-mode double-standby mobile terminal, and can carry out TD-SCDMA and switch to the RAT between the GSM; This field value is an ident value two, and for example integer value 0, represents that this UE is not that TDSCMDA/GSM double-mode double-standby mobile terminal or GSMPS are not in holding state, can not carry out TD-SCDMA and switch to the RAT between the GSM.Information element field in other field that can certainly select to be comprised in the TDD physicalchannel capability field is carried the dual-mode dual-standby sign.
After RNC receives the ability information that UE reports, decode the downlinkPhysChCapability field, if MaxTS-PerFrame information element field value is an ident value two, just represent that this portable terminal do not support RAT to switch, then abandon this field, do not deal with, do not influence the operating state of RNC; If value is ident value one, just represent that this portable terminal support RAT switches, then RNC need preserve one of foundation of this reporting information and the later switch decision of conduct earlier, judge then whether the residing sub-district of current mobile terminal supports this RAT to switch, and whether satisfy some other switching condition, as whether reaching handoff threshold etc., after meeting switching condition, switch to the RAT voice between the GSM just can carry out TD-SCDMA.
Among the present invention, RNC can not obtain the measured value of current GSM BSC adjacent cell, RNC can only recognize whether current mobile terminal supports TD-SCDMA to switch to the RAT between the GSM by dual-mode dual-standby sign position, and recognizes by dual-mode dual-standby sign position whether current GSM PS is in holding state in communication process.The precondition of the present invention's acquiescence is: when needs switch, suppose that the GSM cell signal necessarily is better than the cell signal of TD-SCDMA, like this can be not extensively, also under the not really sound situation, make full use of existing fairly perfect GSM network and provide stable, better more service for the user in the TD-SCDMA network coverage.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
