Specific embodiment

In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with accompanying drawing to this It is bright to be described in further detail, it is clear that described embodiment is only a part of embodiment of the invention, Rather than the embodiment of whole.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing Go out all other embodiment obtained under the premise of creative work, belong to the scope of protection of the invention.

Fig. 1 is a kind of configuration diagram of communication network that the embodiment of the present invention one is provided, in the network architecture Including dominant base 101, the prothetic group station 102 for belonging to dominant base, first terminal 1031 and second terminal 1032, Core net 104.It should be noted that the communication network in the embodiment of the present invention may include multiple dominant bases, Multiple prothetic group stations for belonging to dominant base, multiple terminals, Fig. 1 is only a kind of exemplary plot.

As shown in figure 1, in the coverage of base station 102 and residing in the prothetic group supplemented by first terminal 1031 The terminal of the dominant base 101 of 102 ownership of standing.First terminal 1031 is controlled face letter with dominant base 101 The interaction of breath, and carry out interacting for user plane information with the prothetic group station 102 belonging to first terminal；First terminal 1031 can carry out information exchange by dominant base 101 and core net 104, it is also possible to by prothetic group station 102 Information exchange is carried out with core net 104, or, it is also possible to by dominant base 101 and prothetic group station 102 and core Heart net 104 carries out information exchange.

Second terminal 1032 is another terminal for residing in dominant base 101, second terminal 1032 and dominant base 101 interactions for being controlled surface information and user plane information, and letter is carried out by dominant base 101 and core net Breath interaction.

The embodiment of the present invention takes into account networking scale, specify that polymorphic type base station (dominant base and prothetic group station) is common The technical scheme of networking；By introducing prothetic group station, solving a large number of users and accessing needs higher network capabilities The technical problem held；And, in the embodiment of the present invention, terminal can be controlled interacting for surface information with dominant base, And carry out interacting for user plane information with prothetic group station, it is achieved thereby that chain of command link and user plane link point From establishing control information and business datum between terminal and wireless side access device (all types of base stations) and believe The delivering path of breath.

Chain of command in the embodiment of the present invention is referred to mainly carry and link what is controlled between base station and user Relevant instruction information, the interaction of relevant information and content；User plane refer to user data service information, The interaction and content of relevant information.

In the embodiment of the present invention, the dominant base is macro base station or micro-base station；The prothetic group station is small station or bag Include the virtual base station in multiple small stations.Wherein, macro base station, micro-base station, small station, virtual base station (are referred to as net Unit) communication link can be set up with terminal, network element can disappear after the message for receiving terminal transmission to this Breath is processed accordingly, it is also possible to transmit the message to other network elements, or, it is also possible to disappeared according to this Cease to core network data.

Fig. 2 is the space level of base station and correspondence schematic diagram in the embodiment of the present invention.Specifically, such as Fig. 2 Shown, macro base station and micro-base station can carry out information exchange by wired connection and core net, and small station can pass through Wireless connection carries out information exchange with the macro base station or micro-base station of the small station ownership, in view of it is easy to the demand disposed, Small station can also carry out information exchange by wireless connection with core net.

For example, the interaction of terminal traffic data is illustrated by taking web page browsing or video interactive as an example, The service data request of terminal is reached after network element, and network element needs for service data request to be forwarded to core net.Core After business datum of the heart net according to needed for service data request gets terminal, then by network element by business datum It is sent to terminal.In the process, network element is back to the link of the service data request of core network terminal Pass link.Further, return link can be divided into wired return link (also referred to as wired passback) and wireless Return link (also referred to as wireless backhaul)；Specifically, wired passback refers to that link is consisted of cable or optical fiber, Wireless backhaul refers to that chain route assigned frequency and the frequency resource of bandwidth are carried.

Separately below for the function of the macro base station in the embodiment of the present invention, micro-base station, small station and virtual base station It is specifically introduced.

(1) macro base station：It is mainly used in solving the networking requirements of big region overlay.5th Generation Mobile Communication System In macro base station need the number of resident terminal to be processed more.Simultaneously, it is contemplated that the 5th third-generation mobile communication system Requirement of the system to wireless frequency, macro base station is also responsible for chain of command (i.e. control instruction) information of a large number of users Interaction.

(2) micro-base station：It is mainly used in solving the networking requirements that regional area is covered.5th third-generation mobile communication system In system, due to the introducing in small station, micro-base station can also simultaneously assist macro base station to solve the demand that part covers.

(3) small station：Small station in the embodiment of the present invention is had relatively beyond base stations in mobile communication system type Novel base station form.Although occurring the basic thought in small station in LTE-Advanced correlative studys, With regard to small station definition category always in evolution and renewal.At present, small station covers Home eNodeB (Famtocell), skin station (pico cell being corresponded in ITU, dedicated for hot zone), its definition is turned on Restriction to coverage distance.In 5th Generation Mobile Communication System, the overlay area typically identification in small station is of about Tens meters of radiuses, are mainly used in solving the network capacity requirements of hot spot region.And, needed for the deployment of small station Condition there is also larger difference with macro base station and micro-base station, and it is typically designed using integrated base station, and Simplify many base station parts.

In the 5th Generation Mobile Communication System, small station can also be using further flexible deployment.Only need to carry For common power, typically the business datum of terminal is sent to macro base station or micro- base by the way of wireless backhaul Stand, then core net is sent to by wired return link of macro base station or micro-base station.Or, small station can also lead to Cross wireless backhaul and be directly accessed core network gateway and realize passback of the data to core net.

In addition, it is contemplated that demand of the high speed data transfers business of future customer to Radio Resource broadband, with And the continuous big bandwidth of mobile communication frequency spectrum resource is in the short situation of low-frequency spectra, the 5th third generation mobile communication network In, the control surface information of terminal and macro base station or micro-base station can be set up communication link, and terminal is carried out Wireless data link when high speed data transmission service is transmitted wirelessly is connected realization by setting up with small station.

(4) virtual base station：The communication being directed between small station, by the correspondence between different small stations one is entered Step divides into centralized wireless network (C-RAN) and distributed wireless networks (D-RAN).In view of little The scope of the about tens meters of radiuses in the overlay area stood, terminal may be passed through during business information interaction The overlay area in multiple adjacent small stations, therefore, it is the switching frequency for reducing terminal, can will be adjacent some Individual small station is divided into one group, and in network side a virtual base station is designated generally as.For terminal, it is only capable of The virtual base station is perceived, and cannot be distinguished by currently providing the small station of business service, cut so as to reduce terminal Change.

It should be noted that after being a virtual base station by several small station amalgamated consolidations, terminal is only capable of The mark of the virtual base station is recognized, and is accessed and business data transmission.Meanwhile, also there will be in network The not small station of Virtual base station, such small station still can be independent base station by terminal recognition.Therefore, Virtual base station and not to be constructed as the small station of virtual base station can be independent base station by terminal recognition in network.

As shown in figure 3, building schematic diagram for base station chain of command in the embodiment of the present invention/user plane Radio Link. Control surface information is separated with user plane information in the embodiment of the present invention.

For macro base station present in network, micro-base station, small station/virtual base station multilayer wireless network, terminal Need the Internet for selecting it to access.Therefore, the 5th Generation Mobile Communication System is increasingly complex in this regard.By In the random larger of small station deployment, network topology structure change related frequency, and it is difficult to ensure that little in wide area Stand the continuity for covering, therefore user solves whole communication requirements and unrealistic by small station merely.Meanwhile, Limited frequency spectrum resource is limited to, is to solve the big bandwidth data services application demand of user's two-forty, need to build Found this kind of business demand short-range, that user is met using the base station of larger frequency bandwidth.

In view of above-mentioned practical problem, propose control surface information and use in the 5th Generation Mobile Communication System The detached thought of family surface information, that is to say, that introduce and realize in the design of the 5th Generation Mobile Communication System Chain of command is separated with user plane.Further, it is to ensure that user is full-time online, chain of command link needs to set up In macro base station or micro-base station aspect, both base stations have metastable topological structure, and are equipped with relatively Low frequency is covered with the wireless signal for realizing wide area.Meanwhile, it is the big band width service of reply two-forty, for This kind of user, its user plane is set up in small station/virtual base station aspect.Small station/virtual base station passes through Radio Link The service access admissions control of macro base station and micro-base station is received, directly the spy that business transmission is accessed is carried out with authorizing Determine user and set up user face data link, realize the transmission of user service data.

It should be noted that exist in Fig. 3 that the situation that user plane is linked directly is set up with macro base station or micro-base station, The corresponding customer service of this kind of situation typically belongs to the big band width service of not high speed, or its user moving speed mistake It is high beyond small station/virtual base station can tolerance range, or user terminal is not in the covering of small station/virtual base station In the range of situations such as.Additionally, between small station, due to introducing C-RAN and D-RAN networkings between small station Mode, allows that little interior communication improves data transmission efficiency, therefore, on the data link between small station The data that the user that user plane is linked is set up with small station will be carried.

For the particularity of future terminal high rate data transmission business demand, the embodiment of the present invention is propagated with reference to frequency range A kind of feature, it is proposed that the method for salary distribution that height frequency networking is used.Fig. 4 is different in the embodiment of the present invention Species base station usage frequency planning schematic diagram.

As shown in figure 4, between dominant base (macro base station or micro-base station), dominant base and prothetic group station it is (virtual little Stand or small station) between information exchange is carried out using low-frequency spectra resource；Provided using high frequency spectrum between prothetic group station Source carries out information exchange.

Specifically, the main advantage of low-frequency spectra resource is good propagation characteristic, therefore, the present invention is real Apply in example it is main by low-frequency spectra resource be used for user and macro base station, user and micro-base station chain of command link and User plane link.Meanwhile, small station and macro base station, micro-base station space length farther out, small station and macro base station and The return link of micro-base station is needed also exist for by low-frequency spectra resource bearing.Additionally, for part low rate number According to service-user, and high-mobility users its user plane link also will be by low-frequency spectra.

The main advantage of high frequency spectrum resource is continuous big bandwidth, therefore, in the embodiment of the present invention, in order to By high band transmission range it is short inferior position conversion, mainly by high band resource be used for little interior communication, small station with User plane link between user.The transmission range of these links is short, and the big feature of high band decline makes Obtain the possibility that there are more channelings between small station.Further, since will in the 5th Generation Mobile Communication System Substantial amounts of terminal room communication (D2D) is introduced, this kind of short haul connection also will be using high frequency spectrum resource.

With regard to co-channel interference：Because high frequency, low frequency are the larger frequency range for referring in overall plan of network, Therefore, can pay the utmost attention in concrete networking respectively in high-frequency band and in low frequency band using different Frequency range/carrier wave is used different layer networks/variety classes link networking.When frequency resource is nervous, with frequency group Will there is co-channel interference risk between low-frequency transmission link in upper figure, between high-frequency transmission link in net.
