Description

The transmission method of information and device

Technical field

The present invention relates to the communications field, in particular to a kind of transmission method and device of information.

Background technology

Fast development along with mobile Internet, Internet of Things, particularly intelligent terminal is extensively universal, data traffic sharp increase in wireless network, for building, the expenditure of upgrading wireless Access Network increases year by year, coexisting of multiband multi-modulation scheme also makes network O&M cost high, and every user's average income (Average Revenue PerUser, referred to as ARPU) value do not increase pro rata with data traffic, and these factors have badly influenced profitability and the living space of mobile operator.

In order to solve above-mentioned predicament, industry has proposed to merge the wireless access network solution C-RAN of 4C feature, its core technology comprises: Centralized(concentrates Base-Band Processing), Cooperative(collaboration type radio), the hardware and software platform of Cloud(based on cloud computing framework) and Clean(energy-saving and cost-reducing).The target of C-RAN is to provide a low cost, high-performance, extendible GreenNet framework from long-term angle ，Wei operator, caters to the development of following greatly abundant wireless broadband business in economic mode.NGMN related specifications has been made elaboration to C-RAN solution, and Fig. 1 is that as shown in Figure 1, the solution of C-RAN is specially according to the schematic diagram of the C-RAN network architecture of correlation technique and network element composition:

(1) digital processing element of base station (Digital Unit, referred to as DU) and radio frequency unit (Radio Unit, referred to as RU) are separated disposes: between DU and RU, realize the separation in geographic region, can form dynamically or half dynamic network topology and connect.Communication between DU and RU is with ORI interface and common public radio interface (the The Common Public Radio Interface of standard, referred to as CPRI link, carry, can support the communications protocol of multiband multi-modulation scheme simultaneously, and the interconnecting of different vendor's equipment.

(2) DU concentrates to dispose and forms cloud computing framework: the DU of scale concentrates and is deployed in central machine room or hub transmission, manages concentratedly and dispatches, and forms shared base band resource pool.The baseband signal of the different RU of DU Combined Treatment, thus the morning and evening tides traffic effect in can dynamic adaptation mobile communication system is utilized base-band resource efficiently.

(3) wireless cooperation reduces interference, promoting network performance and user experiences: in C-RAN framework, between DU or between DU cloud, adopt the X2 high-speed channel of X2 interface or enhancing to carry out interconnected, sharing users information, service quality (Quality of Service is processed in Conjoint Analysis, referred to as QoS) index, by many RRU shared logic community, and collaborative multicast communication (Coordinated Multiple Points, referred to as CoMP) technology such as multipoint cooperative, can significantly promote network spectrum efficiency, especially the performance of cell edge.

(4) framework of extensibility and high fault tolerance flexibly: along with the deployment of DU increases, network capacity can for example, smoothly expand to fairly large (for example, surpassing 100 macrocells) from small-scale (, 10 macrocells).A small amount of DU lost efficacy (for example, 10%), can not affect service and performance that whole C-RAN system provides.

C-RAN framework is compared with traditional RAN Access Network, has done a large amount of technological innovations.But these variations have proposed deep challenge to network management, mainly be embodied in two aspects: for the resource pool across DU (Inter-DU Resource Pooling), and the coordinated management of the resource pool in a DU (Intra-DU Resource Pooling).For example: between the DU and RU 1) disposing in separation, can form dynamically or half dynamic topology and connect, in network management, how define and describe this topology and be connected; 2) a plurality of DU polymerizations form cloud computing framework and work in coordination with computing, how to define with this topology of describing between DU and be connected in network management; 3) between many RU, there is the ability of signal combination and user QoS Conjoint Analysis, and DU Yun Zhongduo community can carry out the performance cooperation of up-downgoing, in network management, how define the allocation map relation of DuoRUHe Duo community.

In preliminary specifications at current NGMN about C-RAN, proposed these two kinds of application scenarioss of Inter-DU Resource Pooling and Intra-DU Resource Pooling and corresponding regulatory requirement, but do not provided concrete solution.It should be noted that, the network architecture that C-RAN proposes not is once overturning the defined RAN network of 3GPP, its network resources model can be mapped on the defined logical functional entity of 3GPP, but the defined resource model of 3GPP is more wide in range, can not embody the management expectancy of C-RAN network completely, need to do further refinement and describe more accurately.

Meanwhile, a typical C-RAN website has suffered more massive unit than traditional RAN set of sites, and provides more jumbo community to cover.According to traditional, take a BTS/NodeB/eNodeB and provide the mode of the northbound interface of configuration, alarm, performance and assets as granularity, too grand and extensive, make user in NMS system, be difficult to identify the unit for an overlay area, manage and monitor.
