Embodiment
Because LTE network can not support the speech business in CS (CircuitSwitched, circuit switching) territory, therefore when there is voice service request, LTE network can be connected to 2G or 3G network by SGs interface, thus voice fallback occurs.When CSFB (CircuitSwitchedFallback) voice fallback, if fallen after rise to 2G or 3G network from LTE network, such as ripe UMTS Terrestrial radio access network (UTRAN, or GSMEDGE Access Network (GERAN, GSMEDGERadioAccessNetwork) UMTSTerrestrialRadioAccessNetwork).For the protection of investing circuit switching (CS, CircuitSwitch), in conjunction with the deployment strategy of LTE network, operator can adopt existing CS territory voice scheme to provide voice service, and LTE network only deal with data business.In this case, adopt CSFB technology, namely the subscriber equipment under LTE network covering is when processed voice business, subscriber equipment first return back to CS network, at CS network processes voice, reuse existing CS territory equipment for the user in LTE network with regard to reaching the object of traditional speech business is provided like this.
In CSFB voice fallback process, if LTE network side does not issue GSM frequency when discharging RRC and connecting, CSFB failure can be caused, LTE network side is initiated attachment removal flow process and is fallen net, net registration searched again by subscriber equipment on 3G network (such as TD-SCDMA), to rest on 3G network for a long time just gravity treatment to LTE.In this case, user can not use LTE network for a long time or initiate speech business, and Consumer's Experience is poor.Therefore, need a kind of when the failure of CSFB voice fallback, switch back rapidly the method for LTE network.
In certain embodiments, propose a kind of changing method of voice fallback, as shown in Figure 1, the method comprises the following steps:
Step 102, subscriber equipment initiates voice fallback request to LTE network side.
In certain embodiments, described subscriber equipment can be LTE multimode terminal, and described multimode terminal includes but not limited to compatible LTE, TD-SCDMA, GSM Three models or compatible LTE, WCDMA, GSM Three models.Described LTE network side comprises base station and equipment of the core network etc.
Because LTE network can not support the speech business in CS territory, so when there is voice service request, as shown in Figure 2, subscriber equipment initiates expansion service request to the MME (Mobility Management Entity) of LTE network, comprising CSFB request, trigger after waiting for LTE network side response request and fall flow process after rise.
Step 104, subscriber equipment receives the redirect command that LTE network side issues for voice fallback request.
As shown in Figure 2, after MME receives CSFB request, if user is in connection status, then MME issues the ContextModificationRequest of subscriber equipment to eNodeB (base station); If user is in idle condition, then MME issues IntialContextSetupRequest to eNodeB (base station), and the two all carries CSFB mark.ENodeB issues R8/R9 redirect command (RRCConnectionRelease) to subscriber equipment accordingly.
Step 106, judges whether redirect command carries adjacent area GSM frequency point information, if not, then performs step 108, if so, then performs step 110.
In certain embodiments, GSM frequency point information in adjacent area is used in reference to and draws subscriber equipment and fall back to corresponding GSM network.If redirect command carries adjacent area GSM frequency point information, then subscriber equipment is guided to fall back to corresponding GSM network.If redirect command does not carry adjacent area GSM frequency point information, then start the flow process switching back LTE network, make subscriber equipment switch back LTE network rapidly, and again initiate voice call request.
Step 108, starts the flow process switching back LTE network.
In certain embodiments, if redirect command does not carry adjacent area GSM frequency point information, then CSFB falls after rise unsuccessfully, starts the flow process switching back LTE network, switches back LTE network rapidly to make subscriber equipment.As shown in Figure 3, the flow process switching back LTE network comprises:
Step 128, is set to the 2nd RSRP threshold value by the RSRP threshold value of subscriber equipment by a RSRP threshold value, and wherein, a RSRP threshold value is greater than the 2nd RSRP threshold value.
RSRP (ReferenceSignalReceivingPower, Reference Signal Received Power) be one of the key parameter and physical layer measurement demand that wireless signal strength in LTE network, can be represented, be the mean value carrying the signal power that all RE (resource particle) of reference signal receive in certain symbol.
In certain embodiments, a RSRP threshold value is the current RSRP threshold value of subscriber equipment.2nd RSRP threshold value is the RSRP threshold value of subscriber equipment when starting shooting of mobile phone etc.Such as, by the RSRP threshold value of LTE network by an original RSRP threshold value (such as-114dBm) be set to start shooting time the 2nd RSRP threshold value (such as-128dBm can be obtained by system message SIB1).
Step 148, whether gravity treatment is to LTE network to judge subscriber equipment, if it is performs step 168, otherwise then performs step 188.
In certain embodiments, the signal strength signal intensity of LTE network is constantly monitored.When the signal strength signal intensity (RSRP threshold value) at LTE networking is greater than the 2nd RSRP threshold value, just LTE network gravity treatment can be there is.Such as, when a RSRP threshold value resets to the 2nd RSRP threshold value-128dBm by-114dBm, be just easy to register LTE network.
By the state value of VOICE_REGISTRATION_STATE, just can judge whether gravity treatment is to LTE network.When the state value of VOICE_REGISTRATION_STATE is 1, judge that subscriber equipment gravity treatment is to LTE network; When the state value of VOICE_REGISTRATION_STATE is 0, judge that the non-gravity treatment of subscriber equipment is to LTE network.
Step 168, then reset to a RSRP threshold value by the RSRP threshold value of subscriber equipment.
After subscriber equipment (mobile phone) gravity treatment to LTE network, the modulator-demodulator of subscriber equipment reports login state (VOICE_REGISTRATION_STATE).After modulator-demodulator monitors subscriber equipment gravity treatment to LTE network, just the RSRP threshold value of LTE network is reset to a RSRP threshold value by the 2nd RSRP threshold value.Such as, the 2nd RSRP threshold value reverts to a RSRP threshold value-114dBm by-128dBm.
Step 188, measures LTE network signal strength signal intensity.
When the non-gravity treatment of subscriber equipment is to LTE network, then duplicate measurements LTE network signal strength signal intensity, until when the signal strength signal intensity at LTE networking (RSRP threshold value) is greater than the 2nd RSRP threshold value, subscriber equipment gravity treatment is to LTE network.
Step 1008, judges whether LTE network signal strength signal intensity is greater than the 2nd RSRP threshold value, if so, then performs step 168, otherwise then performs step 188.
When the signal strength signal intensity (RSRP threshold value) at LTE networking is greater than the 2nd RSRP threshold value, just LTE network gravity treatment can be there is.After modulator-demodulator detects subscriber equipment gravity treatment to LTE networking, then the RSRP threshold value of subscriber equipment is reset to a RSRP threshold value.If non-gravity treatment is to LTE networking, then repeat measure LTE network signal strength signal intensity and judge subscriber equipment whether gravity treatment to the step of LTE network, until subscriber equipment gravity treatment is to LTE network.
Above-mentioned steps 128 to step 188, by automatically regulating RSRP threshold value, ensures that subscriber equipment is when LTE low signal areas, can switch fast from 2G or 3G network and get back to LTE network, improve Consumer's Experience.
Step 110, falls back to 2G corresponding to the maximum community of GSM signal strength signal intensity or 3G network by subscriber equipment from LTE network.
If described redirect command carries adjacent area GSM frequency point information, then 2G or 3G network adjacent area are measured, and nearby region measurement value is sorted, then carry out cross-system gravity treatment according to ordering scenario.Described measured value comprises intensity instruction (RSSI, ReceivedSignalStrengthIndicator) or received signal code power (RSCP, the ReceivedSignalCodePower) information of Received signal strength.Particularly, multiple sort method well-known to those skilled in the art can be used to sort to RSSI or RSCP, according to described ranking results, select the strongest community of signal to fall after rise.
In addition, if subscriber equipment is not measured 2G or 3G network adjacent area, then carry out nearby region measurement, reference measurements carries out cross-system gravity treatment.Particularly, those skilled in the art, can adopt the multiple method known to measure Equations of The Second Kind communication network adjacent area, not do too many restriction at this.
