Detailed description of the invention
As stated in the Background Art, in the communication scenes of high-speed mobile, because the terminal device of actual participation transfer of data may belong to the network of different systems, therefore, in order to realize the transmission of network data of multiple types, in the periphery scene of high-speed mobile, need the network facilities of setting up various standards of coupling, have high input and to relate to complexity high.
So, in prior art scheme, lack the data communication package of the network of a kind of less investment and the compatible multiple types of energy, the present invention, in order to solve such problem, based on the overall architecture in existing onboard system coverage mode, has proposed corresponding data transmission scheme.
As shown in Figure 3, the schematic flow sheet of implementation method of a kind of high-speed mobile communications proposing for the embodiment of the present invention, the method specifically comprises the following steps:
The data of one or more standards after the encapsulation that step S301, reception backhaul network send.
In actual application scenarios, data received in this step specifically can comprise following several form:
(1) data of one or more standards that encapsulate respectively according to different systems, described data are carried corresponding ID and service identification.
(2) data of one or more standards of unified encapsulation, described data are carried corresponding standard mark, ID and service identification.
(3) data of one or more standards that encapsulate respectively according to different business, described data are carried corresponding ID and standard mark.
It should be noted that, no matter which kind of above-mentioned form, the object of its most critical is to illustrate the corresponding standard of data, the information of user and type of service, wherein, standard and type of service can become the foundation encapsulating, thereby, realize the differentiation of the data of different systems or different business with the scope of encapsulation of data, the mode that also can identify by interpolation is distinguished, the mode that the data of corresponding different user just identify by interpolation is distinguished, concrete application can be adjusted which kind of above-mentioned form according to actual needs, such variation does not affect protection scope of the present invention.
Further, above-mentioned encapsulation process is according to the difference of subject of implementation, and in this step, received data specifically can be divided into following two kinds of situations:
The data of one or more standards that the base station by described backhaul network that described backhaul network sends encapsulates; Or,
The data of one or more standards that the gateway node by described backhaul network that described backhaul network sends encapsulates.
The selection differences of concrete subject of implementation can not affect protection scope of the present invention.
Step S302, the data of one or more standards after described encapsulation are carried out to decapsulation processing.
In concrete enforcement scene, the content of the decapsulation processing of carrying out in this step, according to the function setting of access point in concrete system, specifically can be divided into following two kinds of situations:
Situation one, in the time that described access point is only realized the function of RRU, the data of one or more standards after described encapsulation are carried out to complete decapsulation processing.
Situation two, when described access point realize simultaneously RRU and function time, the data of one or more standards after described encapsulation are carried out to standard dissection process.
Step S303, the data of one or more standards after decapsulation are sent to the access point of corresponding standard so that the access point of described corresponding standard by data retransmission to terminal device.
Corresponding with two kinds of situations in step S303, in this step, send the data to after access point, the processing procedure in access point comprises two kinds of situations equally:
Situation one, in the time that described access point is only realized the function of RRU, described access point directly sends to corresponding terminal device by data after treatment complete decapsulation.
Situation two, in the time that described access point is realized the function of RRU and BBU simultaneously, the data after standard dissection process are carried out service resolution by described access point to be processed and user's dissection process, and the data of finishing service dissection process and user's dissection process are sent to corresponding terminal device.
Above-mentioned procedure declaration data be sent to the processing mode on the down direction of access point by backhaul network, in actual applications, the handling process that sends to the up direction of backhaul network for access point can realize based on similar processing thinking equally, as shown in Figure 4, concrete handling process is described as follows:
Step S401, receive one or more standards access point send data.
In this step, the concrete function setting of corresponding access point, received data are divided into following two kinds of situations:
Situation one, in the time that described access point is only realized the function of RRU, receive the data of the corresponding standard of the un-encapsulated processing that the access point of described one or more standards sends.
Situation two, in the time that described access point is realized the function of RRU and BBU simultaneously, receive that finishing service Information encapsulation that the access point of described one or more standards sends is processed and the data of the corresponding standard of user profile encapsulation process.
Step S402, by the data that receive unify encapsulation.
Corresponding with two kinds of situations in step S401, in this step, receive after data, concrete data handling procedure comprises two kinds of situations equally:
Situation one, in the time that described access point is only realized the function of RRU, the encapsulation completely that the data that receive are unified.
Situation two, in the time that described access point is realized the function of RRU and BBU simultaneously, the finishing service Information encapsulation that receives is processed and the data of the corresponding standard of user profile encapsulation process are carried out unified standard encapsulation process.
Step S403, the data after unified encapsulation are sent to described backhaul network, so that the data after described unified encapsulation are descapsulated into the data of different systems by described backhaul network, and send to the network equipment of corresponding standard.
Further, above-mentioned decapsulation process is according to the difference of subject of implementation, and the processing procedure sending the data in this step after backhaul network specifically can be divided into following two kinds of situations:
The data after described unified encapsulation are descapsulated into the data of different systems by the base station of described backhaul network, and send to the network equipment of corresponding standard; Or,
The data after described unified encapsulation are descapsulated into the data of different systems by the gateway node of described backhaul network, and send to the network equipment of corresponding standard.
In actual application scenarios; above-mentioned encapsulation and the processing mode of decapsulation also can replace by the mode of setting up corresponding Bearer Channel; thereby; can realize equally above-mentioned techniqueflow; due to the differentiation function of Bearer Channel itself; no longer need above-mentioned encapsulation to conciliate encapsulation process flow process, but all belong to the data in order to distinguish different standards or business and the technological means taked, such variation does not affect protection scope of the present invention.
Compared with prior art, the embodiment of the present invention has the following advantages:
By the technical scheme of the application embodiment of the present invention, between access point in vehicle-mounted processing module and backhaul network and compartment, set up the data processing mechanism in communication mechanism and the vehicle-mounted processing module of clear and definite multi-system data, thereby, can be under the communication scenes of high speed drawings, by the transmission of unified vehicle-mounted processing modules implement multi-system data, improve the stability of transfer of data, and without for multi-system data, transmission increases the hardware input of a large amount of corresponding standards and transforms, having saved corresponding cost drops into, treatment mechanism and design complexities are simplified.
Below, in conjunction with concrete application scenarios, the technical scheme that the embodiment of the present invention is proposed describes.
The embodiment of the present invention is taking the general frame in onboard system coverage mode as shown in Figure 2 as basis, the structure of vehicle-mounted processing module has wherein been proposed to concrete design, and based on this structure, corresponding technical finesse flow process has been proposed, realize the transfer of data solution in high-speed mobile scene.
As shown in Figure 5, the structural representation of a kind of vehicle-mounted processing module proposing for the embodiment of the present invention, specifically comprises:
E-UE(EvolvedUserEquipment, enhanced user equipment), be responsible for carrying out transfer of data by air wireless interface (Uu mouth) and the bakchual network equipment.
IFU(IntegratedFunctionUnit, function integrated unit) integrated different functional process unit according to the actual requirements, and complete corresponding processing capacity.
DPU(DataProcessingUnit, data processing unit) be responsible for specifically processing from the data of AP in backhaul network and compartment, specifically comprise the AP to corresponding standard by the Data dissemination from backhaul network, be issued to terminal by AP, to packing and encapsulate from the data of AP, and be sent to backhaul network by E-UE.
In the design that the embodiment of the present invention provides, the functional localization of E-UE and DPU is clear and definite, and the function of IFU can consider with the standard of AP and implementation, realizes design flexibly.
Describe as an example of the AP of LTE standard example below.
In LTE system, base station equipment (eNB) is made up of two core processing units conventionally, is respectively baseband processing unit (BuildingBasebandUnit, BBU) and RF processing unit (RadioRemoteUnit, RRU). Wherein the major function of BBU is to realize the functions such as the encapsulation of data, scheduling, modulation /demodulation and encoding and decoding, and the major function of RRU is the transmitting-receiving that completes radiofrequency signal by antenna. Between BBU and RRU, carry out data and information interaction by Ir interface. While considering IFU function and the division of LTEAP function, there are two kinds of basic implementations, as shown in Figure 6.
In scheme 1, AP only realizes RRU function, and BBU function is realized by the IFU of vehicle-mounted processing module, between AP and IFU, communicates by Ir interface.
In scheme 2, AP realizes the function of BBU and RRU simultaneously, and the IFU of vehicle-mounted processing module realizes the protocol function of X2 interface, and AP communicates by X2 interface and IFU.
The function of the each module under two schemes is divided as shown in table 1.
Functions of modules in table 1 scheme 1 and scheme 2 is divided
In such scheme 2, adopting X2 interface to realize communicating by letter between IFU and AP is a kind of possible mode, also can adopt other standard interface or define new interface standard.
As shown in Figure 7, the schematic flow sheet of implementation method of a kind of high-speed mobile communications proposing for the embodiment of the present invention, the method specifically comprises the following steps:
Step S701, backhaul network are to carrying out encapsulation process from the data of external network (core net that various standards are corresponding).
Wherein, the method for encapsulation comprises as the various ways in step S301, mainly contains following several:
(1) data of various standards are encapsulated respectively, and add respectively ID and service identification, distinguish different user without business.
(2) by unified the data of different systems encapsulation, and add standard mark, ID and service identification, distinguish the business of each user under different systems.
(3) encapsulate according to type of service, and add standard mark and ID, distinguish the different user under different systems
The function of data encapsulation can complete by the base station equipment of backhaul network, also can add gateway node and be responsible for specially encapsulation and the decapsulation function of data.
After completing data encapsulation, data are sent to vehicle-mounted processing module by backhaul network.
The E-UE of step S702, vehicle-mounted processing module is responsible for receiving the data that backhaul network sends, and DPU carries out decapsulation to data, and by IFU module, data is sent to corresponding AP.
It is to be noted, the function difference that IFU realizes, data distributing is also different to the mode of AP, still taking above-mentioned LTEAP standard as example, if the RRU function that AP only realizes, DPU will carry out complete decapsulation to data so, and each user's business datum is sent to respectively to AP, and AP directly sends to terminal and needn't process again; If AP has realized BBU and RRU function simultaneously, DPU only need be by the Data Analysis of LTE standard out so, and needn't resolve the user/business information of deep layer, after data are sent to AP, send to corresponding user by the parsing of AP completing user and service level and by data.
The data that receive are sent to user by step S703, each AP.
Accordingly, upstream data process of transmitting is also divided into three steps, as described below.
The upstream data of reception is sent to vehicle-mounted processing module by the AP of step S704, each standard.
In this step, if AP only realizes RRU function, data are not carried out to extra process, be only responsible for receiving and forwarding; If AP has realized RRU function simultaneously, the encapsulation of completing user and business data simultaneously, sends to vehicle-mounted processing module by the data after encapsulation.
The DPU of step S705, vehicle-mounted processing module is responsible for the user data of the various standards that receive to unify encapsulation, and the step 2 in the mode of encapsulation and downlink data reception flow process is similar. After completing encapsulation, by E-UE, data are sent to backhaul network.
The data that receive are carried out decapsulation by step S706, backhaul network, and the data of just each standard send to corresponding core net node.
It is to be noted; data encapsulation and decapsulation process are the one possibility modes of carrying out data communication between node; another common mode is to set up bearer path; itself has mark action passage; and needn't in packet, add extra mark; but its essence and directly interpolation mark in packet indifference, such variation does not affect protection scope of the present invention.
