2nd, when private network break station be property problem etc. it is non-transmitting due to cause, and when being difficult to restore, the utility model Interim solution can be provided.It can quickly be opened near breakpoint first with microwave, the provisional RRU device on public network site, and It cell structure altogether is formed with private network RRU, both provided interim covering for private network breakpoint, also avoid at breakpoint and public network is cut It changes.

Cell networking structure is total to high ferro private network below to be introduced.

As shown in fig. 7, in high ferro private network, BBU and RRU (or RRU and RRU) is connected using microwave.

Microwave is often jumped to be made of two sets microwave equipments, wherein a set of CPRI ports by optical fiber and higher level's website (BBU or RRU CPRI ports connection)；Another set of CPRI ports are connect by optical fiber with the CPRI ports of subordinate's website (zooming out RRU). It is interconnected between two sets of microwave equipments by microwave antenna.

In a common cell structure, k-hop microwave can be used, k is the positive integer more than or equal to 1, while k is less than or equal to altogether RRU quantity in cell structure.

According to the erection environmental condition of microwave, following two different systems can be used in microwave：

As shown in figure 5, zoom out RRU and information source station BBU using microwave connection.

As shown in fig. 6, the RRU of RRU and higher level's website is zoomed out using microwave connection.

(referring to Fig. 7 institutes in the common cell system of high ferro private network RRU mixed transport mode networkings that the present embodiment is provided Show), between other websites for optical fiber limitation problem do not occur, still connected using optical fiber.When between BBU and RRU or RRU Between RRU, when can not use optical fiber transmission or optical fiber transmission failure, replaced using microwave transmission.Microwave replaces optical fiber The common cell structure of RRU and other private networks RRU composition of micro-wave extension can't be influenced afterwards, and the switching with public network will not occur, Not only it ensure that network quality, but also the time has been striven in the reparation for breakpoint station.

Now even if net opens the case that RRU zooms out station using microwave public network is all few, more not in high ferro private network Use precedent.Therefore, the utility model considers the data transmission of BBU, RRU in the microwave of selection connection BBU and RRU Data interaction amount between agreement and specification, BBU and RRU and RRU and RRU, final choice 10GE microwaves.

BBU and RRU is connected by 10GE microwaves, on the one hand, enough capacity of eating dishes without rice or wine can be provided, meet CPRI agreements end The requirement of mouth data interaction amount, part type product can also establish 3 CPRI links, while open 3 RRU websites, meet Multisystem RRU zooms out the needs at station；On the other hand, the typical transmission distance of 10GE microwaves is 1000 meters or so, exactly matches height The iron private network station spacing that is averaged is approximately less than 1000 meters of network condition.

Website is zoomed out because property is when reasons can not be restored the short time, as shown in figure 3, the prior art is special when private network It is directly bridged using public network base station (emergency car) behind the disconnected station of net, the switching between private network and public network will occur, network quality is uncontrollable.

The common cell system of high ferro private network RRU mixed transport mode networkings that the present embodiment is provided, as shown in fig. 7, by In using RRU (or emergent RRU website for temporarily installing) of the microwave by public network base station, with private network information source station BBU or private network other The RRU for zooming out station is connected, and merges into common cell structure with private network RRU, will not occur at private network breakpoint in this way and public affairs The switching of net, not only ensure that network quality, but also the time has been striven in the reparation for breakpoint station.

The switching flow based on the networking structure is introduced below.

Based on the common cell system of above-mentioned high ferro private network RRU mixed transport mode networkings, in high ferro UE moving process Handoff procedure is not related to the switching with public network, is described as follows.

If private network zooms out after physics site 3 interrupts in Fig. 3,8, the covering of private network between private network physics site 2 and 4 is no longer Continuously, physics site 3 cannot such as be restored in time.It then can only be by such as the public network base station of Fig. 3 positions or emergency car progress private network Bridge joint.

When application the utility model, the RRU of bridging stations is opened using microwave, and the RRU of bridging stations is merged into private network Common cell structure in (Fig. 8), then the handoff procedure for the system that the utility model embodiment is provided is as follows：

1. with the traveling of train, when the signal of UE from occupancy physics site 1 is changed into the signal of occupancy physics site 2 When, since the RRU of physics site 1 and physics site 2 belongs to same cell structure (cell1) altogether, so without switching.

The 2nd, the interim covering solution of high ferro breakpoint is provided

When cannot restore in short term the problems such as high ferro zooms out RRU website property.It is attached breakpoint can quickly to be opened first with microwave Provisional RRU websites on nearly public network site, and cell structure altogether is formed with private network RRU, both provided temporarily for private network breakpoint Covering, also avoids at breakpoint and the switching of public network.

And existing network technology, using public network site website is covered near breakpoint temporarily when, attribute itself is as public network Base station, so the switching between private network and public network necessarily occurs, industry network quality and user's perception can not all ensure.

3rd, RRU will be zoomed out whenever and wherever possible to be merged into the common cell structure of private network

Using the utility model, whether restore private network website or open temporary site, as long as it is open-minded by microwave Zoom out RRU, all can easily be merged into the common cell structure of private network, under the premise of not switching completely with public network, Fast quick-recovery or the covering for making up private network.

Under existing network technology, do breakpoint bridge joint whether by public network base station and still open emergency car, all can not change its public affairs The attribute of base station is netted, the common cell structure of private network can not be merged into, also can not just avoid the switching between private network and public network, industry network Quality and user, which perceive, can not all ensure.

It 4th, can be as " the high ferro private network emergency car " of high-efficiency and economic

The utility model provide it is a kind of efficiently and effectively, break station emergency guarantee means for high ferro private network.Whether it is extensive Multiple private network website still opens temporary site, and the utility model, which plays the role of to be equal to, " can be merged into private network and be total to cell The Emergency communication vehicle of structure " after fault recovery can easily be removed with rapid deployment, quick open-minded and transition arrives other Trouble point uses.

Compared with common emergency car, the utility model has advantage following prominent：

First, it can be merged into the common cell structure of private network：It zooms out RRU using what microwave was opened and can be directly merged into specially In the common cell structure of net, become a part for private network；And common Emergency communication vehicle, although and by microwave it is open-minded, its Connection is BBU and core net, is open-minded as a stand-alone base station, it is impossible to and the common cell structure of private network website composition, it is inevitable It can switch as public network base station with private network, reduce network quality.

Secondly, deployment is extremely rapid：It only needs to install, adjust logical microwave, data aspect in terms of the utility model deployment The setting of wireless side low volume data can be only related to, therefore opened and zoomed out RRU and only need several hours；Common emergency car is opened It is logical need by, the links such as decorating position is reconnoitred, field deployment, transmission and wireless side data creating need Sectors cooperation, so Service time is long, and normally opening needs 48 hours or more.

Again, cost is extremely cheap：The price of mesh previous dive 10GE microwaves is at 100,000 yuan or so；And one common emergent logical Believe the price of vehicle between 200~3,000,000.Implement the utility model, the 10GE microwaves needed are only the 1/20 of common emergency car To between 1/30, cost performance is high.
