Description
Technical field
The present invention relates to wireless communication technology field, particularly a kind of method, system and equipment of Radio Link monitoring.
Background technology
In LTE (Long Term Evolution, Long Term Evolution) system, Radio Link detects at down direction (DL) and up direction (UL) and is realized by UE (terminal) and eNodeB (evolution base station) respectively.
At down direction, terminal physical layer detects the signal strength signal intensity of eNodeB pilot channel and carries out mutual with RRC (Radio Resource Control, Radio Resource control) layer.When the radio link quality variation and when reaching certain condition, rrc layer is thought Radio Link Failure and initiate RRC connection re-establishment process.During reconstruction; The terminal will be carried out the cell selecting process and attempted seeking suitable E-UTRA (Evolved Universal Terrestrial Radio Access; The evolved universal terrestrial wireless access) sub-district is sent RRC connection re-establishment request and is carried the information of rebuilding reason to eNodeB afterwards.ENodeB is after the RRC connection re-establishment request that receives the terminal, if find that eNodeB changes, eNodeB will notify former eNodeB UE Radio Link to fail to the former eNodeB transmission Indication message at terminal so.Former eNodeB can take corresponding operating in view of the above, as deleting terminal contextual information etc.
At up direction, the eNodeB usual way has: 1, detect according to RRC connection re-establishment request, promptly eNodeB can judge Radio Link according to the cause value that carries in the message and once fail after the RRC connection re-establishment request that receives the UE transmission; 2, eNodeB detects according to the transmitting and scheduling situation that AM (Acknowledged Mode, answer-mode) mode wireless carries last packet.AM packets need transmission is being arranged, but under the situation of transmission failure always, eNodeB can judge that Radio Link fails.
In recent years, along with popularizing of mobile Internet (Mobile Internet) and smart mobile phone, the mobile data traffic demand rapidly increases, and indoor data service has occupied a large portion ratio.Indoor and hot spot data service feature for the user be generally fixing perhaps very low speed move, less demanding to mobility; On the other hand, data service is mainly based on the Internet of IP (Internet Protocol, Internet Protocol) professional, and is more single to the requirement of QoS (Quality of Service, service quality), and well below the requirement of carrier class business to QoS.Traditional cell mobile communication systems mainly towards be high-speed mobile, the professional design of the carrier class of seamless switching, when it carried big flow low speed IP data packet traffic, efficient was on the low side, cost is too high.
To sum up, honeycomb mobile operator need find out low cost, and high power capacity is fit to the solution that the indoor wireless data insert.Main solution is at present:
Home eNodeB (Femto; Femtocell formula base station) as solving other a solution indoor and hot zones data service flow demand, indoor distances is shorter according to covering, the characteristics that number of users is less; Reduce the capacity requirement and the merit emissivity at single station; Usually number of users is at 8-20, and power and mobile phone terminal are suitable, generally below 23dBm.
The relative indoor covering system of Home eNodeB and little base station, cost is lower, dispose more flexible, the effect of business experience of having played certain indoor data.But its deficiency is: Home eNodeB is not optimized to indoor data service characteristics; With the LTE system is example; LTE Femto system has adopted the protocol infrastructure and the Interface design of LTE system complete basically; So the complicacy of realization, just base station capacity and power reduce, so cost is high always.In addition; Femto is IMT (International Mobile Telecommunications; International mobile telecommunication) equipment in the system; Its frequency that can work is still authorized frequency range for the operator in the IMT, and the bandwidth that relative WiFi can use is less, can't satisfy operator's data service shunting demand fully.
The cost of existing LTE Femto is higher relatively, has compared a certain distance with wifi (Wireless Fidelity, adopting wireless fidelity technology), has therefore introduced a kind of new network access system, i.e. LTE-LAN (Long Term Evolution local area network (LAN)) system.Because the Radio Link detection has been removed by the LTE-LAN system, the AM transmission mode, processes such as RRC connection re-establishment make that the Radio Link testing mechanism in the existing LTE system can't use.Under this environment; Be moved when the terminal and exceed the coverage of LTE-LANAP; Perhaps the wireless channel environment variation causes the radio signal quality variation; When perhaps the terminal causes this abnormal conditions of Radio Link Failure to occur because of reasons such as power down inefficacies suddenly, the LTE-LAN system can't detect the terminal wireless link network will take place to interrupt and break away from.
In sum; Network takes place to interrupt and break away from because the LTE-LAN system can't detect the terminal wireless link; Make the LTE-LAN system to administer and maintain operation to the terminal that breaks away from network according to normal procedure, this will cause the waste of system user and control resource.
