In embodiments of the present invention, in the time that UE detects mutual interference, eNB is switched to alien frequencies carrier wave (CC) as main carrier (PCC) according to disturbed condition using UE, or for UE reconfigures auxiliary carrier wave (SCC), or UE directly reconnects after measuring and receives alien frequencies CC as PCC.Like this, alien frequencies CC is arrived in UE gravity treatment in the time being subject to mutual interference, and then avoids mutual interference.Wherein, mutual interference comprises the mutual interference of device interior existence and/or the mutual interference of device external.
Base station can be by (maximum 5 of the carrier wave compositions of multiple quantity; Each maximum 20MHz; Frequency can be continuous, also can be discontinuous) gather together, for terminal provides service.Maintain with terminal the carrier wave that RRC is connected, be referred to as PCC; Carrier wave except main carrier, is referred to as SCC.In the situation of discontinuous carrier polymerization, be all called alien frequencies CC with other CC of this CC different frequency.Each terminal only has a PCC, and PCC also connects for carrying RRC except transfer of data, and remaining SCC is only for transfer of data, and can activate and the processing of flyback work according to service condition.
Embodiment mono-is under connection status, and when UE side PCC exists mutual interference, UE is switched to alien frequencies carrier wave CC, and the alien frequencies CC being switched to is as PCC.Embodiment bis-and embodiment tri-are under connection status, and UE side SCC exists mutual interference, flyback described SCC alive, and redistribute UE available resources.Embodiment tetra-and embodiment five are under idle condition, and UE side PCC exists mutual interference, UE gravity treatment CC, and the CC of described gravity treatment is as PCC.
Embodiment mono-
In mobile terminal, WLAN and LTE-Advanced coexist, and referring to accompanying drawing 2, LTE-Advanced CC1 uses 2380MHz～2400MHz frequency range, CC2 uses 2340MHz～2360MHz frequency range, CC3 uses 2300MHz～2320MHz frequency range, and 3 CC frequency ranges, at a distance of nearer, provide identical coverage.
The current PCC of UE is CC1, and in RRC connection status, the not SCC in state of activation.When the transmitting of the WLAN of mobile terminal module, when LTE-Advanced module receives, WLAN module can produce very strong interference to the reception of LTE-Advanced module; Or when the transmitting of LTE-Advanced module, when WLAN module receives, LTE-Advanced module can produce very strong interference to the reception of WLAN module.
For fear of the mutual interference between WLAN and LTE-Advanced, for LTE-Advanced side, in the time detecting that WLAN is in running order, adopt following steps to avoid the mutual interference between WLAN and LTE-Advanced in mobile terminal, referring to accompanying drawing 3, be specially:
Step 301:UE detects when WLAN is in operating state, judges between the current resident CC1 frequency of UE and WLAN frequency of utilization and has stronger mutual interference, sends mutual interference indication information to eNB.
Step 302:eNB receives after the mutual interference indication information that UE reports, and sends RRC connect reconfiguration information to UE, makes the Reference Signal Received Power (RSRP) of UE to all alien frequencies CC measure.If alien frequencies CC meets access PCC requirement, this alien frequencies CC is reported.
Access PCC requires the RSRP that is included in alien frequencies CC in the TTT time to be more than or equal to default threshold value.TTT set of time is for being less than different-frequency measure cycle 200ms, allocating and measuring criterion threshold value S-criterion.In the time there is multiple suitable alien frequencies CC, report so simultaneously, be chosen in suitable alien frequencies CC by eNB judgement and above the PCC of UE received.
Step 303:UE receives RRC and connects after reconfiguration information, reshuffles measurement, starts the measurement to alien frequencies CC, and reports RRC to reshuffle information to eNB.
Step 304:UE carries out alien frequencies CC measurement, search channel quality and meet the alien frequencies CC that access PCC requires, meet alien frequencies CC2 and CC3 that access PCC requires, report the measurement result to all alien frequencies CC to eNB, in this information, comprise the CC mark that meets PCC access conditions.
Step 305:eNB receives after the measurement result of UE, and the alien frequencies CC that judges receivability UE is CC3, initiates PCC handoff procedure, and is its distributing radio resource on CC3, sends RRC connect reconfiguration information to UE, and UE is switched to CC3 as PCC.The measurement of UE is to carry out on all CC that configure at eNB, and measurement result is the alien frequencies CC that is receivability UE without the CC of mutual interference.
Step 306:UE receives after RRC reconfiguration information, carries out RRC reconfiguration course, resides in new PCC and goes up and carry out uplink random access, sends RRC and has reshuffled information.
After the PCC of UE is switched to CC3, because the frequency of CC3 is 2300NHz～2320MHz, so and mutual interference between WLAN can be smaller, avoided the mutual interference between mobile device built-in system.
Embodiment bis-
In mobile terminal, Bluetooth and LTE-Advanced coexist, the up CC1 of LTE-Advanced uses 2550MHz～2570MHz frequency range, up CC2 uses 2500MHz～2520MHz frequency range, up CC3 uses 2000MHz～2020MHz frequency range, 3 CC frequency ranges are at a distance of nearer, provide identical coverage, shown in accompanying drawing 2.
The current PCC of UE is CC1, and in RRC connection status, CC2 is the SCC in state of activation, and CC3 is the SCC in anti-state of activation.When the transmitting of the Bluetooth of mobile terminal module, when LTE-Advanced module receives, Bluetooth module can produce very strong interference to the reception of LTE-Advanced module; Or when the transmitting of LTE-Advanced module, when Bluetooth module receives, LTE-Advanced module can produce very strong interference to the reception of Bluetooth module.
For fear of the mutual interference between Bluetooth and LTE-Advanced, for LTE-Advanced side, in the time detecting that Bluetooth is in running order, adopt following steps to avoid the mutual interference between Bluetooth and LTE-Advanced in mobile terminal, shown in accompanying drawing 5, be specially:
Step 401:UE detects when Bluetooth is in operating state, judge between CC1 frequency that UE current PCC is resident and Bluetooth frequency of utilization, disturb less, but the SCC that UE activates, be to have stronger mutual interference between CC2 and Bluetooth frequency of utilization, therefore send mutual interference indication information to eNB.Wherein, judging whether to exist mutual interference is prior art.
Step 402:eNB receives after the mutual interference indication information that UE reports, and sends instruction to UE, makes UE temporarily stop the transmission of data in buffering area.
Step 403:UE receives after the instruction of eNB transmission, stops sending the data in buffering area, immediately flyback CC2 alive.
Step 404:CC3 is arranged in and can activates CC set, and according to the data volume in buffering area, UE judgement need to activate new CC and carry out transfer of data, and UE activates CC3, and has reshuffled information to eNB transmission SCC.UE can safeguard and can activate CC list behind persistent district, and the available CC that equipment of UE itself can be supported gathers, and comprises SCC under PCC, activation/anti-state of activation etc.
Step 405:eNB receives after the CC active information that UE reports, on CC1 and CC3 again for UE distributes up available resources;
Step 406:UE recovers the transmission of upstream data in buffering area;
After the SCC of UE is switched to CC3 from CC2, because the frequency of CC1 is 2550MHz～2570MHz, the frequency of CC3 is 2000MHz～2020MHz, so and mutual interference between Bluetooth can be smaller, avoided the mutual interference between mobile device built-in system.
Embodiment tri-
In mobile terminal, WLAN and LTE-Advanced coexist, the up CC1 of LTE-Advanced uses 2000MHz～2020MHz frequency range, up CC2 uses 2500MHz～2520MHz frequency range, up CC3 uses 2520MHz～2540MHz frequency range, 3 CC frequency ranges are at a distance of nearer, provide identical coverage, as shown in Figure 2.
The current PCC of UE is CC1, and in RRC connection status, CC2 is the SCC in state of activation, and CC3 is the SCC in anti-state of activation.When the transmitting of the WLAN of mobile terminal module, when LTE-Advanced module receives, WLAN module can produce very strong interference to the reception of LTE-Advanced module; Or when the transmitting of LTE-Advanced module, when WLAN module receives, LTE-Advanced module can produce very strong interference to the reception of WLAN module.For fear of the mutual interference between WLAN and LTE-Advanced, for LTE-Advanced side, in the time detecting that WLAN is in running order, adopt following steps to avoid the mutual interference between WLAN and LTE-Advanced in mobile terminal, as shown in Figure 5, be specially:
Step 501:UE detects when WLAN is in operating state, judge between CC1 frequency that UE current PCC is resident and WLAN frequency of utilization, disturb less, but the SCC that UE activates, be to have stronger mutual interference between CC2 and WLAN frequency of utilization, therefore send mutual interference indication information to eNB;
Step 502:eNB receives after the mutual interference indication information that UE reports, and sends instruction to UE, makes UE temporarily stop the transmission of data in buffering area.
Step 503:UE receives after the instruction of eNB transmission, stops sending the data in buffering area, immediately flyback CC2 alive.
Frequency range frequency of utilization same and WLAN in step 504:CC3 place is close, be subject to stronger mutual interference, thereby can activate CC set for empty, UE can not activate new CC and carry out transfer of data, only on CC1, can carry out transfer of data, send SCC to eNB and reshuffled information.
Step 505:eNB receives UE and reports after available CC information, on CC1 again for UE distributes up available resources.
Step 506:UE recovers the transmission of upstream data in buffering area.
At live CC2 and without new SCC activation of UE flyback, because the frequency of CC1 is 2000MHz～2020MHz MHz, so and mutual interference between WLAN can be smaller, avoided the mutual interference between mobile device built-in system.
Embodiment bis-is whether can activate new CC with the difference of embodiment tri-is carried out data transmission.When activating new CC, utilize original PCC and activate new CC and transmit data; When there is no to activate new CC, utilize original PCC to transmit data.
Embodiment tetra-
In mobile terminal, Bluetooth and LTE-Advanced coexist, LTE-Advanced CC1 uses 2380MHz～2400MHz frequency range, CC2 uses 1900MHz～1920MHz frequency range, CC3 uses 2600MHz～2620MHz frequency range, 3 CC frequency range apart from each others, due to reasons such as Electromagnetic Wave Propagation physical characteristics, these 3 CC frequency ranges provide different coverages, as shown in Figure 6.
The current PCC of UE is CC1, and in RRC idle condition, the not SCC in state of activation.When the transmitting of the Bluetooth of mobile terminal module, when LTE-Advanced module receives, Bluetooth module can produce very strong interference to the reception of LTE-Advanced module; Or when the transmitting of LTE-Advanced module, when Bluetooth module receives, LTE-Advanced module can produce very strong interference to the reception of Bluetooth module.For fear of the mutual interference between Bluetooth and LTE-Advanced, for LTE-Advanced side, in the time detecting that Bluetooth is in running order, adopt following steps to avoid the mutual interference between Bluetooth and LTE-Advanced in mobile terminal, as shown in Figure 7, be specially:
Step 701:UE detects when Bluetooth is in operating state, judges between the current resident CC1 frequency of UE and Bluetooth frequency of utilization and has stronger mutual interference.Send mutual interference indication information to eNB;
Step 702:eNB receives after the mutual interference indication information that UE reports, and sends instruction to UE, makes UE temporarily stop the transmission of data in buffering area.
Step 703: after the lasting TTT time, UE startup is measured the RSRP of all alien frequencies CC.If alien frequencies CC meets access PCC requirement, will record this alien frequencies CC.
Access PCC requires the RSRP that is included in alien frequencies CC in the TTT time to be more than or equal to default threshold value.TTT set of time is for being less than different-frequency measure cycle 200ms, allocating and measuring criterion threshold value S-criterion.In the time there is multiple suitable alien frequencies CC, report so simultaneously, be chosen in suitable alien frequencies CC by eNB judgement and above the PCC of UE received.
Step 704:UE carries out prioritization to all CC that detect according to prior art.The original frequency priority of being listed CC under eNB by system message is: CC2>CC1>CC3, according to the suffered mutual interference situation of each CC, downward exists the priority of mutual interference CC to bottom, raise without the priority of mutual interference CC to top, and it is constant to maintain relative priority order, CC prioritization now becomes CC2>CC3>CC1.
Step 705: require and have limit priority because the measurement result of CC2 meets to access, UE gravity treatment CC2, as PCC, disconnects current PCC, and the RRC on CC1 connects, and re-establishes RRC connection to eNB request immediately on CC2.
Step 706:eNB carries out CC acceptance judging, is UE allocation radio resource, and sends RRC connection reconfiguration information to UE, and the PCC of UE is switched to CC2 from CC1.
Step 707:UE receives RRC and connects reconfiguration information, carries out the switching of PCC, and connects to eNB transmission RRC the information of having reshuffled.
Step 708: in the time that UE detects that Bluetooth quits work, judge that the mutual interference between CC1 frequency and Bluetooth frequency of utilization disappears, the frequency priority of CC1 is recovered, now the frequency prioritization of each CC becomes: CC2>CC1>CC3.
After the PCC of UE is switched to CC2, because the frequency of CC2 is 1900MHz～1920MHz, so and mutual interference between Bluetooth can be smaller, avoided the mutual interference between mobile device built-in system.
