Fig. 3 is that access network section composer carries out network section to F-RAN, generates four kinds of typical sections schematic diagrames；Fig. 3 a It is the schematic diagram of wide area seamless coverage network dicing method embodiment of the present invention based on F-RAN；Fig. 3 b are based on F- for the present invention The schematic diagram of the focus high capacity network dicing method embodiment of RAN；Fig. 3 c are big connection Internet of Things of the present invention based on F-RAN The schematic diagram of network dicing method embodiment；Fig. 3 d are that the present invention highly reliable network dicing method of the low time delay based on F-RAN is implemented The schematic diagram of example；Fig. 4 is the unified frame structure that each section of the present invention based on F-RAN is used.

As illustrated in figs. 3 a-3d, described four kinds typical application scenarios are specifically included：It is wide area seamless coverage, focus high power capacity, big Connection Internet of Things, low time delay high reliable communication；Wherein, wide area seamless coverage performance objective is to pursue connection and 100,000,000 all the time The Consumer's Experience speed of bits per second, focus high power capacity performance objective is to pursue the peak transmission speed for being up to ten Gigabits per seconds Rate, big connection Internet of Things pursues every square kilometre of connection number more than million, and the end that low time delay high reliable communication pursues Millisecond is arrived Terminal delay time and close transmission reliability very.

In this step S101, more specifically operation content includes：

(1) for wide area seamless coverage application scenarios, as shown in Figure 3 a, to pursue seamless coverage, non-hot region is serviced The communication of mobile subscriber, in the four corner for needing to dispose the section of wide area seamless coverage Radio Access Network, advises according to network The portfolio and its coverage with each region are drawn, high power node (High Power Node, HPN) is disposed, configuration RF transmitter and base band processing device that HPN is configured using its own, in local controller, also referred to as lan controller Finishing service data and control information processing function with the help of (Local Controller), and provide business datum and/or Control signaling.HPN of the present invention can be traditional macro base station or micro-base station, be configured with extensive multiple antennas or distribution The enhanced macro base station of formula antenna configuration or cloud base station, for realizing to the backward compatible of existing cell mobile communication systems With the seamless coverage for ensureing wireless network.

HPN has complete physical layer, data link layer, the core net function that Internet and part are sunk on demand；Ginseng See Fig. 3 a, to realize the Consumer's Experience speed of 100Mbps, HPN is low using below the 6GHz with good channel propagation characteristics Frequency range, lifts spectrum efficiency, and by optimizing transmission power and handoff parameter, improve data transfer by extensive antenna technology Speed, reduces cutting off rate；To support bigger bandwidth, data transmission rate is lifted using bigger bandwidth, as shown in figure 4, physical layer is adopted With bigger subcarrier spacing, the integral multiple 30kHz of such as 15kHz shortens frame length, if the 5ms divided exactly by 1ms, with compatible long-term Evolution (Long Term Evolution, LTE) frame structure；Physical layer can continue to use OFDM (Orthogonal Frequency Division Multiplexing, OFDM) and OFDM (Orthogonal Frequency Division Multiple Access, OFDMA) technology, or the new multi-transceiver technology such as (Filtered OFDM, F-OFDM) With the new multiple access technology such as sparse CDMA (Sparse Code Multiple Access, SCMA), and low-density parity The new modulation coding techniques such as verification (Low Density Parity Check, LDPC) code, polarization code, super Nyquist modulation, Lifting user's concatenation ability and spectrum efficiency；Data link layer, Internet continues to use default configuration, including using optimization coverage Hybrid automatic repeat-request (Hybrid Automatic Repeat reQuest, HARQ).

Additionally, HPN has heterogeneous network converged function, can realize and other isomery radio access nodes, such as wireless office The radio access node of domain net or wireless MAN, or the visible optical access node of millimeter wave, carry out isomery collaboration fusion；Together When, HPN can carry out communication exchanges with other sections, be that other sections and node provide business datum and/or control signaling, such as There is dynamic realtime between baseband processing unit (Building Baseband Unit, BBU) pond in HPN and cloud computing server Back haul link interface, the collaborative signal processing between BBU ponds, RRM and movement in realization and cloud computing server Property management.

Or, (2), for focus volume applications scene, are raising radio transmission speed as shown in Figure 3 b, will be using big Scale antenna, centralized cloud wireless access or isomerization polymerization technology；To meet flux density demand, section can be accessed by increasing Point deployment density, the mode such as lifting spectrum efficiency and increase bandwidth is realized.Using data/control isolation technics, chain of command is by matching somebody with somebody The HPN of standby extensive antenna is supported, it is ensured that the transmitting of signaling；Data surface is needing portion using centralized cloud wireless access In the region of administration's focus high power capacity Radio Access Network section, according to the network planning and the portfolio and its covering model in each region Enclose, dense deployment remote radio-frequency heads (Remote Radio Head, RRH), realize closely leading to using big bandwidth high frequency and terminal Letter, the RRH of configuration utilizes the front end radio frequency signal and simple Symbol processing module of its own configuration, finishing service data Transmitting-receiving and simple process, and BBU ponds are passed back to by fronthaul (forward pass circuit), at the cooperative signal using BBU ponds Reason and pooling of resources scheduling, complete the business support of data surface.

More specifically, it is multiple more than the regional deployment of specified density more than specified services amount or access density in portfolio F-AP, and popularity is high, and the big business of repetitive requests rate is preferentially pushed in F-AP and other base stations with caching, described There is F-AP mist to calculate baseband signal processing module, can carry out hot spot capacity absorption.

F-AP not only has the front end radio frequency signal and simple Symbol processing module of tradition RRH, it may have base band Signal physical treatment and RRM control module, for realizing and adjacent, preferable other F- of back haul link situation AP carries out distributed collaborative communication, while direct communication and resource management also can be carried out with the communication terminal for accessing this F-AP.Often Individual F-AP all directly using forward link connection cloud computing server in BBU ponds, while with the F-AP of surrounding have business and Control interface, realizes the collaboration communication between F-AP, by wireless mesh under the management in BBU ponds that can be in cloud computing server Net Mesh, tree topology, linear topology or star topology realize interconnecting for multiple F-AP in subrange, realize business It is shared, while in the case of reducing dense deployment, the interference between F-AP.

BBU ponds include physical layer, data link layer, Internet and more top function, and RRH only has the simple radio frequency work(of physical layer Can and Symbol processing function, physical layer remaining Base-Band Processing function is accumulated in BBU pool；Each node protocol stack function sets Meter scheme is consistent substantially with wide area covering section, as shown in figure 4, frame structure design parameter can be according to focus high power capacity scene Channel and business characteristic do corresponding optimization；Transmission time interval (Transmission Time Interval, TTI) sets more long Value, to carry more data stream, when interference environment is relatively simple, can introduce flexibly duplex or full duplex；Modulating-coding can be used Higher order modulation mode and Geng Gao code checks.Preferably, due near terminal, it is possible to carry out data surface using high band and lead to Letter, meets the requirement of focus high power capacity.Identical with HPN, BBU ponds have heterogeneous network section fusion function, can be cut for other Piece carries out resource management calculating, and by the exchange between section, for other sections provide business datum and/or control signaling；Examine Consider high band super large bandwidth, the characteristics of covering is small, signal directive property is strong, frame structure should also be as being optimized accordingly, sub- load Wave spacing can increase to 150kHz is arrived, and frame length can further shorten, and waveform removes the OFDM and new ripple used using low-frequency band Shape F-OFDM etc., it is also possible to use single carrier, improve power utilization；Using time division duplex (Time Division Duplexing, TDD) pattern and extensive antenna, extensive antenna compensates path loss high by adaptive wave beam shaping and tracking The influence for bringing.

Or, (13) connect Internet of Things application scenarios for big, as shown in Figure 3 c, in order to reduce user resources dynamic dispatching band The control signaling expense come, using the contention access mode for exempting from scheduling based on sub-clustering, positioned at same node point F-AP or same height Intelligent terminal part MANET in power node HPN coverages, terminal uses terminal direct connection technology and relay multi-hop in cluster Technology, each nodal information by the node processing of cache business, or can be aggregated into cluster head in cluster, by cluster head access network；Cluster The caching capabilities of the basis for selecting node of head, can linking number, certain nodal cache ability is stronger in cluster, and traffic handing capacity is got over Height, while present position is suitable, enables to more intelligent terminals while accessing the node, while the node and network insertion Node connection state is good, then the node be chosen as cluster head probability it is bigger；Each cluster head with do not possess the non intelligent of networking capability Terminal reduces signaling consumption by the contention access mode access node for exempting to dispatch, it is ensured that the terminal of extensive quantity can be same When access network.

For the node with caching capabilities in cluster, the sinking of chain of command function is more likely to so that the cluster that node is constituted With distributed business service ability；Multiple terminal nodes are connected with each other by interface in cluster, may make up wireless mesh network Mesh topologys, tree topology, linear topology or stelliform connection topology configuration；In same F-AP coverages, terminal is mutually interconnected Connect, wireless mesh network topology structure is set up under the management of F-AP, when having certain node failure in network or cannot work, F- AP can carry out resource adjustments distribution, and carry out information transfer by way of building new route；Or terminal node is F-AP's The wireless tree topology network architecture is set up under management, the node in wireless tree topology can be carried out by connecting new node Extension, is easy to the management to terminal node.

It is relatively low to channel width in view of big connection Internet of Things application scenarios, be responsible for coverage access node F-AP or HPN, can, fragment frequency spectrum scattered using low-frequency range or even part OFDM subcarriers；Designed by using narrowband systems, lifting Section covering power, increases access device number and reduces power consumption of terminal and cost；To reduce power consumption of terminal, using significantly enhanced Power-saving mechanism, receives (Enhanced Discontinuous Reception, eDRX), energy saver mode by the way that enhancing is discontinuous Technical optimization connection status such as (Power Saving Mode, PSM), reduces the opening time, increases paging interval, optimizes data Gather and report frequency so that the terminal longer time is in Low-power-consumptiodormancy dormancy state.

There is complete physical layer, data link layer, Internet, and partial function to sink what is constituted for HPN and F-AP Upper layers；Physical layer is primarily upon how efficiently supporting that magnanimity is connected, can be using the frame long of narrow bandwidth so that F-AP, HPN can carry out multi-user data and include and dispatch by cluster head；Waveform can be using the new waveform technology such as F- based on efficient filtering OFDM, GFDM etc., reduce out-of-band interference, using scattered frequency spectrum and fragment frequency spectrum, effectively realize the decoupling of intersubband technical scheme, So that modulating-coding of different sub-band etc. can carry out separate configurations；Multi-access mode is using such as anon-normal handing-over of new multiple access technique Enter mechanism MUSA, can realize being multiplexed the single connection more than 3 times on single running time-frequency resource, with the Overflow RateHT more than 300%, And with relatively low complexity.

Compared to wide area covering and focus high power capacity, big connection Internet of Things business has small data packets, magnanimity connection, strong burst The characteristics of property, therefore its data link layer and network layer protocol stack can not completely reuse the above two respective protocol stack, it is necessary to enter Row recombinates and merges to reduce the expense of protocol stack；Preferably, in attaching process, using exempting to dispatch contention access mode, simplify Signaling process, reduces user's access delay and system signaling expense；The head compression and encryption of omitted data link layer, reduce data Treating capacity；Total amount in view of data is big, and partial error data can be omitted, radio link layer control protocol (Radio Link Control, RLC) therefore entity be configured to UM, reduces number of retransmissions；Internet optimizes simplifies mobile management, connection management, The signaling processes such as roaming, reduce overhead.

Or, (4) as shown in Figure 3 d, in order to reduce forward node, reduce for low time delay high reliable communication application scenarios Forwarded time delay, can use local cache mist access node F-AP or terminal direct connection, and the F-AP has front end less radio-frequency Signal and Symbol processing module, it may have baseband signal physical treatment and RRM control module, and can access this F- The communication terminal of AP carries out direct communication and resource management；Dynamic ad hoc network network structure is carried out between F-AP, dynamic Mesh is set up and is led to Letter link, holding equipment and terminal room single-hop and multi-hop communication, realize the storage of distribution of resource formula and the interaction of information, reduce road By forward node number, end-to-end time delay is reduced；Be improve link reliability, when back haul link in order when, F-AP can be used Distributed collaborative communication is carried out with other adjacent F-AP, between realizing F-AP under the management in the BBU ponds in cloud computing server Joint transmission, when back haul link situation is not ideal enough, using dual link, while access F-AP and configuration it is extensive enter it is many Go out the HPN of technology (Multi-input Multi-output, MIMO).

F-AP and HPN have a physical layer of extreme simplification, data link layer, to ensure the low latency that business is transmitted, therefore And complete protocol stack function is not needed, it is necessary to carry out the cross layer design of protocol stack；As shown in figure 4, physical layer frame structure is used The short frame structure of short TTI, it is ensured that dispatching cycle it is short and small quick, while to ensure certain data payload, therefore use big bandwidth. Because short TTI designs can cause Cyclic Prefix (Cyclic Prefix, CP) expense excessive, it is contemplated that use the filtering without CP , used as waveform, its filtering for being based on subcarrier can be simultaneously for device group multicarrier (Filter Bank Multi-Carrier, FBMC) More flexible adaptation channel variation；Multiple access technology is using new multiple access technologies such as SCMA, it is to avoid resource allocation flow, realizes up Data packet dispatching " zero " stand-by period；Modulating-coding uses the skill upgrading single-link reliability such as advanced encoder and space-time frequency division collection Property.

Data link layer can simplify or omit head compression and encrypt, and reduce processing delay；Using the HARQ of self adaptation, in height Under signal to noise ratio channel condition, HARQ is omitted, lower time delay, under low signal-to-noise ratio channel condition, using enhancing optimization HARQ, lifting Retransmission performance, increases link reliability, reduces number of retransmissions；Scheduling contention access is exempted from using high priority, it is ensured that terminal Quickly access.Preferably, under the scene of part, F-AP and HPN needs Network layer function, now needs to optimize connection status, reduces Terminal RRC state switching time, partial function needs to sink to Upper layers, such as local paging, mobile content localization.

If application scenarios are not belonging to the above four kinds typical application scenarios, can by access network section composer according to Using feature and wireless network working condition, determine that the application is the application correspondence between four kinds of mixed modes of typical case's application Section also can by it is above-mentioned typical case application section mixing constitute.

S102：According to all kinds of status informations for perceiving, access network section composer modification wireless network section protocol is protected The hard isolation of card section.

In this step, according to user, terminal, business, the access network status information for perceiving, access network section composer Modification wireless network section protocol, optimization section configuration, it is ensured that hard isolation during section operation；The hard isolation refers to section root When disposing operation according to section protocol, mutually it is independent of each other between difference section, whether the operation conditions of a section does not interfere with well The normal work of other sections.Fig. 5 is that access network section composer is modified to each section protocol in step S102, is realized hard The operating procedure flow chart of isolation, shown in reference picture 5, in step s 102, more specifically operation content includes；

S201, based on the section blueprint for determining, with reference to the global perception information for obtaining, access network cuts into slices composer to section Scheme is modified.

The section blueprint that access network section composer will determine as template, with reference to the user, terminal, business for perceiving, Access network status information, modification generation wireless network section protocol carries out the hard isolation of corresponding section, is given under different sections Caching distribution and caching working method, Radio Resource and distribution, transmission mode；Wherein, the section blueprint includes that network is advance The section blueprint of storage, also including according to traffic performance, by the section blueprint of multiple section blueprint mixing generation, a same net Network is cut into slices blueprint, can according to the actual requirements with network environment, removal part flows and functionality, and generates different section Network Dept.s Management side case；

S202, section composer determines each section cache resources and caching working method.
