Description
Technical field
The present invention relates to Control on Communication field, in particular to a kind of mode of operation switching wireless network access device
Method.
Background technology
Mobile communication system refer to operator by dispose wireless access network equipment (such as base station), and equipment of the core network (as
Attaching position register, Home Location Register, HLR) etc., provide communication service for user terminal (such as mobile phone)
System.Mobile communication experienced by the first generation, the second filial generation, the third generation, forth generation.The standard of forth generation mobile communication system is in the world
Long Term Evolution (Long Term Evolution/Long Term that is upper relatively uniform, that formulate for International Organization for Standardization 3GPP
Evolution-Advanced, LTE/LTE-A), it is descending directly enters (Orthogonal Frequency based on orthogonal frequency is many
Division Multiple Access, OFDMA), up directly enter (Single Carrier based on single carrier frequency division is many
Frequency Division Multiple Access, SC-FDMA) access way, according to bandwidth and self adaptation flexibly
Modulation coding mode, reached downlink peak rates 1Gbps, the high-speed transfer of upstream peak speed 500Mbps.Fig. 1 is brief
Show the basic framework of mobile communications network.
For working in the base station of unauthorized frequency range, according to whether depend on mandate frequency range to include both of which:
The first, needing to rely on the pattern authorizing the resource of frequency range normally to work, i.e. system message and RRC etc. needs logical
Crossing mandate band transmissions, data can be by unauthorized band transmissions, and such as LAA be (Licensed-Assisted Access's
Write a Chinese character in simplified form) and LTE-U (Long Term Evolution in unlicensed spectrum writes a Chinese character in simplified form) in unauthorized frequency range
All as secondary cell (SCell).
Another kind of, it is not necessary to authorize the pattern that the resource of frequency range just can work alone, i.e. full detail can be awarded non-
Unauthorized frequency range in power band transmissions, such as MuLTEfire can be as main plot (PCell).
For the above-mentioned mode of operation needing dependence mandate frequency range, the use of unauthorized frequency range depends entirely on awards
The working condition of power frequency range, therefore to decrease in the reliability of business.As a example by LAA, its typical scene such as Fig. 2 (a) is extremely

Power carrier wave) work in the LAA scene 1 of macro base station and little base station respectively for, when macro base station or back haul link (backhaul)
When going wrong, all go well also cannot normally provide the user industry even if small is cell (only operating in unauthorized frequency range)
Business.The most such as small cell supports to authorize frequency range and the scene of unauthorized frequency range simultaneously, when small cell is authorizing frequency range
When being configured to close, also cannot continue working in the UE transmission system message authorizing frequency range and receiving upward signal
(R13LAA does not support unauthorized band transmissions upward signal) etc..And for not relying on the mode of operation authorizing frequency range,
The feature of unauthorized frequency range itself is i.e. disturbed uncontrollable and is caused reliability to be less than and authorize frequency range.
Need to rely on for the wireless network access device working in unauthorized frequency range in prior art and authorize frequency range, cause industry
The problem that business reliability reduces, the most not yet proposes effective solution.
