Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Now, along with the development of network technology, operator can dispose multiple standard network usually simultaneously in the wireless network, but because subscriber equipment is (English: User Equipment, being called for short UE) speed that updates far lags behind the speed of operator deployment New Schemes network, therefore operator is caused can not to make the decision of closing any one standard network easily, multiple standard network is worked simultaneously becomes inevitable trend, wherein, above-mentioned standard network includes but not limited to: Generation Mobile Telecommunication System technology is (English: second generation, be called for short: global system for mobile communications 2G) is (English: global system for mobile communications, be called for short: GSM), time division multiple access is (English: Time Division Multiple Access, be called for short: TDMA), G mobile communication is (English: 3rd-generation, be called for short: code division multiple access 3G) is (English: Code Division Multiple Access, be called for short: CDMA), TD SDMA is (English: Time Division-Synchronous Code Division Multiple Access, be called for short: TD-SCDMA), Wideband Code Division Multiple Access (WCDMA) is (English: Wideband Code Division Multiple Access, be called for short: W-CDMA), universal mobile telecommunications system is (English: Universal Mobile Telecommunications System, be called for short: UMTS), high speed downlink packet access technology is (English: High Speed Downlink Packet Access, be called for short: HSDPA), and forth generation mobile communication technology is (English: the 4 Generation mobile communication technology, be called for short: Long Term Evolution 4G) is (English: Long Term Evolution, be called for short: LTE) etc.And WLAN (wireless local area network) (English: Wireless Local Area Networks, be called for short: WLAN) can the advantage of high speed data transfer within the specific limits with it, be widely used in cellular networks.So just, occurred the network coverage of WLAN be just in time in simultaneously at least two kinds of standard networks Zone switched on scene, namely when UE is in the network coverage of certain WLAN AP, when can measure at least two standard network of network parameters (e.g., signal strength information).Communication network under this scene can ensure that UE carries out the transmission of data service by wlan network usually as much as possible, and carries out business transmission by the standard network that signal strength signal intensity is best.
Based on foregoing description, embodiment provided by the invention is applied to multiple types network and wlan network is combined in the communication network of deployment, as shown in Figure 1, this communication network 1 comprises: base station 11, UE12 and wireless local network connecting point (Wireless Local Area Networks Access Point is called for short WLAN AP) 13.Wherein, above-mentioned base station 11 comprises the first base station 111 corresponding to current the connected standard network of UE12, and the second base station 112 (e.g., e-NodeB or NodeB) that other standard networks are corresponding.Simultaneously in this communication network 1, this UE is at least two standard networks (L1, L2, Ln, n>=2) Zone switched in, UE can measure the signal strength signal intensity of the base station of each standard network of these at least two standard networks.It should be noted that, Fig. 1 is that be only here example, in practical application scene, this UE may be in the Zone switched of two or at least two standard networks for two standard networks (the first standard network and the second standard network).
Embodiment one
Based on the communication network schematic diagram shown in Fig. 1, The embodiment provides a kind of changing method based on multi-mode networks, in base station side, as shown in Figure 2, the method specifically comprises the steps:
201, the first measurement report of base station receives user equipment UE transmission.
Wherein, the base station in the embodiment of the present invention is the base station that standard network that this UE is current connected is corresponding, the first namely above-mentioned base station.Concrete, when in the network coverage that UE rests on some WLAN AP (the target WLAN AP namely in the present invention) for a long time, then the network parameter of this WLAN AP is reported base station by measurement report by this UE.Wherein, above-mentioned network parameter includes but not limited to: the signal strength information, service set (English: Service Set Identifier, to be called for short SSID), channel etc. of WLAN AP.
202, base station receives the second measurement report that UE sends.
Wherein, the second above-mentioned measurement report comprises the signal strength information of each standard network at least two standard networks that UE measures.Exemplary, the signal strength information of 2G network is generally: the signal strength signal intensity instruction of reception is (English: Received Signal Strength Indication, be called for short: RSSI), the signal strength information of 3G network is generally: received signal code power is (English: Received Signal Code Power, be called for short: RSCP), the signal strength information of 4G network is generally: and Reference Signal Received Power (English: Reference Signal Receiving Power, be called for short: RSRP).Concrete, UE can periodically measure each standard network of regional deployment residing for this UE, and the measurement data of each standard network measured formation measurement report is reported base station; UE also can when determining that this UE rests in the network coverage of target WLAN AP for a long time, each standard network of regional deployment residing for this UE is measured, and the measurement data of each standard network measured is formed measurement report reports base station.
Concrete, UE periodically or acyclic each WLAN AP to this UE periphery and each standard network respective base station measure, and the measurement data of the measurement data of each WLAN AP measured and each standard network formed measurement report report base station.
203, when according to the network parameter of target WLAN AP, base station determines that UE rests in the network coverage of target WLAN AP for a long time, base station, according to the signal strength information of each standard network, adjusts the handoff threshold value that each standard network is corresponding.
Concrete, in the network parameter of the target WLAN AP sent according to UE when this base station this WLAN AP detectable signal (beacon (Beacon) signal) in SSID information and when determining that this UE can rest in the network coverage of this target WLAN AP for a long time, in order to prevent this UE net between different standard networks frequently between switch, cause the decline even call drop of UE quality of service, this base station can obtain the signal strength information of each standard network at least two the standard networks disposed the current region of UE, so that corresponding handoff threshold value between suitable adjustment each standard network is carried out according to the size of the signal strength information of each standard network in this base station, UE is made to reside in the large standard network of signal strength information as much as possible, reduce UE at the number of times switched between the internetwork net of each standard.
And above-mentioned at least two standard networks comprise: the first standard network and the second standard network.Above-mentioned handoff threshold value triggers the handoff threshold value of standard network switching.Exemplary, with reference to Fig. 1, when the network coverage of the WLAN AP in Fig. 1 is just in time in UMTS network and LTE network Zone switched middle simultaneously, if when UE needs to be switched to UMTS network from LTE network, measured value M1 (e.g., the M obtained after then needing the signal quality of UE to LTE community to measure
rSRP, the Reference Signal Received Power of LTE community) and the signal quality of UE to UMTS community measure after measured value M2 (e.g., the M that obtains
rSCP, the received signal code power of UMTS community) and meet following switching condition simultaneously: M1<L1; M2>L2.Wherein, L1 is the handoff threshold value of LTE network, and L2 is the handoff threshold value of UMTS network.
Exemplary, if the current region of UE deploys the first standard network and the second standard network, and the signal strength information of this first standard network is greater than the signal strength information of this second standard network, then the handoff threshold value of the second standard network is just improved in this base station, reduce the handoff threshold value of the first standard network, rest on as much as possible in the first standard network to make UE.Accordingly, if the current region of UE deploys the first standard network, the second standard network and the 3rd standard network, and the signal strength information of the first standard network is maximum, then this base station improves the handoff threshold value of the second standard network and the 3rd standard network respectively, reduce the handoff threshold value of the first standard network, rest on as much as possible in the first standard network to make UE.
204, the handoff threshold value after each standard network adjustment is sent to UE by base station, thus restriction UE switches between the internetwork net of each standard.
Concrete, base station is at the signal strength information of each standard network reported according to UE, after the handoff threshold value corresponding to each standard network adjusts, just the handoff threshold value of each standard network after adjustment is sent to this UE, with make this UE to net according to the handoff threshold value of each standard network after adjustment between switch, because the handoff threshold value of the maximum standard network of signal strength information has been turned down in base station, heightened the handoff threshold value of other standard networks simultaneously, thus make this UE be switched in the maximum standard network of signal strength information as much as possible, namely UE is made to rest on as much as possible in the large standard network of signal strength information.It should be noted that, base station is after adjusting the handoff threshold value of each standard network, do not revise the handoff threshold value of each standard network of original storage in base station, be only by the adjustment of each standard network after handoff threshold value send to corresponding UE, adjust according to the handoff threshold value after adjustment to make this UE.
The changing method based on multi-mode networks that the embodiment of the present invention provides, base station receives user equipment is at the first measurement report comprising the network parameter of target WLAN AP determining to send after in the network coverage that this UE rests on target WLAN AP for a long time, and receive the second measurement report of UE transmission, then the signal strength information of each standard network at least two the standard networks measured according to UE in the second measurement report, adjust the handoff threshold value that each standard network is corresponding, and the handoff threshold value after each standard network adjustment is sent to UE, thus restriction UE switches between the internetwork net of each standard, UE is made to rest in the large standard network of network coverage as much as possible, thus decrease the number of times that UE switches between standard network, avoid because of UE net between different standard networks frequently between switch the decline even problem of call drop of customer service quality of causing, saved the power consumption of UE for handover measurement simultaneously.
Optionally, as shown in Figure 3, when above-mentioned at least two standard networks be the first standard network and the second standard network time, step 203 specifically comprises following content:
203a, when according to the network parameter of target WLAN AP, base station determines that UE rests in the network coverage of target WLAN AP for a long time, and the first standard network of network coverage is greater than the second standard network of network coverage, then the handoff threshold value of the first standard network is reduced by second predetermined threshold by base station, and the handoff threshold value of the second standard network is increased by second predetermined threshold.
Wherein the second predetermined threshold is by base station sets, to the reference value that the handoff threshold value of networks with different systems improves or reduces, this second predetermined threshold is relevant with specific implementation, can set according to actual conditions base station, also can be the measurement report synthetic setting that base station reference UE reports base station.
Concrete, when base station is according to the threshold value switched between the network coverage adjustment network of networks with different systems, the handoff threshold value of standard network maximum for network coverage can be reduced by second predetermined threshold, and the handoff threshold value of other standard networks increases by second predetermined threshold, the signal quality measured values making UE corresponding to the standard network that network coverage is maximum is greater than the handoff threshold value of this standard network, and the signal quality measured values corresponding to other standard networks is less than the handoff threshold value of its standard network, thus make UE reside in the maximum standard network of signal strength information as far as possible, reduce between the net of UE between networks with different systems and switch.
Exemplary, the associating deployment scenario schematic diagram of the multi-mode networks of reference shown in Fig. 1 and wlan network, when the network coverage of the WLAN AP in Fig. 1 is just in time in UMTS network and LTE network Zone switched middle simultaneously, the method specific implementation process that the present embodiment provides as shown below, wherein, UMTS network of network coverage is greater than the network coverage of LTE network.
Concrete, when base station learns that UE has rested in the network coverage of the WLAN AP shown in Fig. 1 for a long time, in order to prevent this UE net between UMTS network and LTE network frequently between switch, cause the decline even call drop of UE quality of service, this base station needs to adjust the handoff threshold value that this UE carries out switching between UMTS network and LTE network, make this UE reside in UMTS network (network coverage is large), avoid UE to carry out unnecessary network and switch.Wherein, in the prior art, UE is switched to UMTS network from LTE network needs to meet following switching condition simultaneously:
M
RSRP<L1；
M
RSCP>L2。
Wherein, M
rSRPuE obtains the RSRP of this LTE community measured value to the measurement of LTE community, M
rSCPbe the measured value of UE to the RSCP of this UMTS community that the measurement of UMTS community obtains, L1 is the handoff threshold value of LTE network, and L2 is the handoff threshold value of UMTS network.
Concrete, base station is when the handoff threshold value switched between UMTS network and LTE network UE adjusts, because UMTS network of network coverage is greater than the network coverage of LTE network, therefore, UMTS network can be accessed in order to make UE and can not be switched in LTE network, the handoff threshold value L1 of LTE network suitably can be improved in base station, reduces the handoff threshold value L2 of UMTS network simultaneously.Such as, can add a side-play amount (Offset) (i.e. the second predetermined threshold) in handoff threshold value, now, the switching condition that UE is switched to UMTS network demand fulfillment from LTE network is as follows:
M
RSRP<L1+Offset；
M
RSCP>L2-Offset。
So just M can be made
rSCPbe easier to the handoff threshold value being greater than UMTS network, M
rSRPbe easier to the handoff threshold value being less than LTE network, namely stop in a umts network always, network not easily occurs and switches, thus decrease the number of times switched between net.Wherein, the value of above-mentioned Offset can set according to actual conditions base station, also can be the measurement report synthetic setting that base station reference UE reports base station.
Exemplary, with reference to Fig. 1, if when the network coverage of the WLAN AP in Fig. 1 is just in time in the network coverage of GSM network, UMTS network and LTE network simultaneously, because the network coverage of GSM network is maximum.Therefore, base station in order to avoid UE mobile intermediate frequency numerous net between different standard networks between switch, the adjustment UE that this base station can be suitable in the internetwork handoff threshold value of carrying out switching of each standard, thus ensures that this UE stops in gsm networks all the time.Concrete, this base station can reduce the handoff threshold value K1 of GSM network, improves handoff threshold value K2 and the K3 of UMTS network and LTE network simultaneously.Such as, be in LTE network when UE is current, base station, in order to ensure that UE switches between netting no longer frequently, needs the switching condition between this UE is from LTE network to GSM network to adjust, by Mx<K3; My>K1, is adjusted to Mx<K3+H; My>K1-H.Wherein measured value Mx (e.g., the M that obtains after measuring of the signal quality of UE to LTE community
rSRP) and the signal quality of UE to GSM community measure after measured value My (e.g., the M that obtains
rSCP).
The changing method based on multi-mode networks that the embodiment of the present invention provides, base station receives user equipment is at the first measurement report comprising the network parameter of target WLAN AP determining to send after in the network coverage that this UE rests on target WLAN AP for a long time, and receive the second measurement report of UE transmission, then the signal strength information of each standard network at least two the standard networks measured according to UE in the second measurement report, handoff threshold value corresponding for standard network large for signal strength information is turned down, handoff threshold value corresponding for standard network little for signal strength information is heightened, and the handoff threshold value after each standard network adjustment is sent to UE, thus restriction UE switches between the internetwork net of each standard, UE is made to rest in the large standard network of network coverage as far as possible, thus decrease the number of times that UE switches between standard network, avoid because of UE net between different standard networks frequently between switch the decline even problem of call drop of customer service quality of causing, saved the power consumption of UE for handover measurement simultaneously.
Based on the communication network schematic diagram shown in Fig. 1, The embodiment provides the another kind of changing method based on multi-mode networks, in UE side, as shown in Figure 4, the method specifically comprises:
301, when in the network coverage that UE determines this UE target approach WLAN AP, UE records the time that this UE stops in the network coverage of target WLAN AP.
Concrete, the attribute information of the WLAN AP of UE periodicity or acyclic measurement periphery is (as signal strength information, as received signal strength (Received Signal Strength, be called for short RSS), SSID), and according to the attribute information of each WLAN AP measured, and after learning the network coverage entering a certain WLAN AP, this UE just can start to record this UE and rest on time in the network coverage of this target WLAN AP.
Optionally, step 301 specifically comprises the steps:
301a, when in the network coverage that UE determines UE target approach WLAN AP, UE opens timer, and the time stopped in the network coverage of target WLAN AP by timer record UE.
Concrete, when UE enters after in a certain WLAN AP network, open timer T and the time stopped in the network coverage of this WLAN AP by this timer T record UE, when reaching the timing range that this timer is preset, then determine that this UE can rest in the network coverage of this target WLAN AP for a long time, and using this WLAN AP as target WLAN AP.In addition, timer can reset in following scene by UE: 1) when UE leaves the network coverage of WLAN AP, and this UE can stop the timing of timer to be reset by timer simultaneously; 2) when UE sends the first measurement report to base station, illustrate that this UE has completed the timing to target WLAN AP, now, timer is reset.
302, the time of staying stopped in the network coverage of target WLAN AP as UE, when being greater than the first predetermined threshold, UE obtained the network parameter of target WLAN AP.
