Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, a portable wireless broadband central station can only be fixed and used as a Long Term Evolution (LTE) base station to provide network services for terminal devices within a coverage area of the base station, but networking cannot be performed between the portable central stations, so that communication cannot be performed between the portable central stations, and further, problems of information blocking, information cannot be transmitted in time and the like are caused. Furthermore, although the LTE-Advanced (LTE-Advanced) introduces the feature of in-band relaying, the in-band relaying generally consists of two parts, namely a Relay Node (RN) and a base station (Node B, NB), and only supports one-hop relaying. Although some vendors have also introduced proprietary protocol products that support multihop inband relaying, the end-to-end bandwidth drops dramatically over multiple hops.
In view of this, embodiments of the present application provide a networking method and a communication apparatus, which enable a portable central station to support multiple operating modes through a software radio technology, so as to achieve the purpose of communication among multiple portable central stations.
Fig. 1 is a schematic diagram of a network architecture of a networking method according to an embodiment of the present application, and please refer to fig. 1, where the network architecture includes an electronic device and a plurality of portable central stations to be networked, the electronic device may be linked with each portable central station in a wired or wireless manner, and one portable station is used to provide a network server for a terminal device in a coverage area of the portable station. The electronic device may be a terminal device, a server, or the like, and may determine an operation mode of each portable central station and indicate the operation mode to the corresponding portable central station according to the number of portable central stations to be networked, the location of each portable central station, and the like. The position of the portable central station refers to the position of the portable central station in a first sequence, and the first sequence is used for indicating the arrangement sequence of the portable central stations when the portable central stations to be networked are linearly networked. For example, a total of 4 portable central stations are identified as a, b, c, and d, and according to the first sequence, the sequence of the portable central stations in the linear networking of the portable central stations is: the positions of the portable central station a, the portable central station b, the portable central station c and the portable central station d are 1, 2, 3 and 4 in sequence.
Hereinafter, a networking method according to an embodiment of the present application will be described in detail based on the architecture shown in fig. 1. For example, see fig. 2. Fig. 2 is a flowchart of a networking method provided in an embodiment of the present application, where the embodiment explains the networking method from an interaction perspective of an electronic device and a first portable central station, and the embodiment includes:
101. the electronic device determines the number of portable central stations to be networked.
For example, the electronic device may determine the number of portable central stations to be networked in any feasible manner. For example, a technician writes the number into a configuration file, and the electronic device reads the configuration file to obtain the number of portable central stations to be networked; for another example, the electronic device provides an input interface on which the technician enters the quantity, which the electronic device recognizes.
102. The electronic device determines a location of a first portable central station according to a first order.
The first sequence is used for indicating the arrangement sequence of the portable central stations to be networked during linear networking, and the first portable central station is any one of the portable central stations to be networked.
Illustratively, for any one of the portable central stations to be networked, hereinafter referred to as the first portable central station, the electronic device determines the position of the portable central station in the first order according to the first order. The first sequence is used to indicate an arrangement sequence of the portable central stations to be networked, for example, there are five portable central stations in total, where the identifiers are a, b, c, d, and e, and when the 5 portable central stations are linearly networked, the arrangement sequence is the portable central station a, the portable central station b, the portable central station c, the portable central station d, and the portable central station e in turn, then the positions of the 5 portable central stations are 1, 2, 3, 4, and 5, and the positions are used to indicate the positions of the corresponding portable central stations in the first sequence.
103. And the electronic equipment determines the working mode of the first portable central station according to the number and the position of the first portable central station.
The working mode comprises a host base station mode, a relay base station and terminal equipment mode or a double-terminal mode.
Illustratively, the first portable central station adopts a software radio architecture, a physical layer and a Media Access Control (MAC) layer of the first portable central station are implemented by a Digital Signal Processing (DSP) device, a dedicated accelerator, a Micro Control Unit (MCU), and the like, and a high-level protocol of the first portable central station is implemented by an MCU, so that the first portable central station can support 3 operation modes and support switching of the operation modes by software radio technology, and the 3 operation modes include a host base station support mode, a relay base station and terminal device support mode, or a dual-terminal mode. When networking is performed, which mode the first portable central station works in is determined by the electronic equipment according to networking requirements, such as the position of the first portable central station and the number of the portable central stations to be networked, and the like, the working modes of the portable central stations at different positions can be different or the same, for example, the working modes of the portable central stations are the same when the portable central stations are at odd positions; as another example, the portable central stations in the even and odd positions operate in different modes.
104. The electronic equipment sends indication information to the first portable central station.
Accordingly, the first portable central station receives the indication information from the electronic device.
In this step, the electronic device sends an indication message to each of the first portable central stations, i.e., the portable central stations to be networked, so as to indicate the operation mode of the portable central station to each of the portable central stations. For example, the portable central station has interfaces, such as a network management interface, a process management interface, and the like, and the electronic device may send the indication information to the first portable central station through any one of the interfaces.
105. And the first portable central station is networked with other portable central stations in the portable central stations to be networked according to the working mode.
Illustratively, the first portable workstation mode of operation loads different software modules to facilitate networking of other portable central stations. For example, when the operation mode is the base station mode, the first portable central station is used as a host base station of a subordinate portable central station; for another example, when the working mode is a double-terminal mode, the first portable central station is communicated with the upper portable central station and the lower portable central station; for another example, when the operation mode is the relay base station and terminal device mode, the first portable central station serves as a relay device to realize the communication between the upper portable central station and the terminal device.
According to the networking method provided by the embodiment of the application, the electronic equipment determines which working mode of a host base station mode, a relay base station and terminal equipment mode or a double-terminal mode the first portable central station works in according to the number of portable central stations to be networked and the position of the first portable central station in the arrangement sequence of the portable central stations during linear networking, and indicates the working mode to the first portable central station, so that the first portable central station is networked with other portable central stations according to the working mode. In the process, the portable central station can support multiple working modes, and the electronic equipment can determine the working modes during networking from the multiple working modes, so that the purpose of communication networking among multiple portable central stations is realized.
Next, the three operation modes supported by the first portable central station in the embodiment of the present application will be described in detail.
First, a base station mode.
Fig. 3 is a schematic diagram of a portable central station in a base station mode in a networking method according to an embodiment of the present application. Referring to fig. 3, when the first portable central station is in the base station mode, it is a dual transmit-dual receive (2T 2R) LTE base station, and includes a Radio Frequency (RF) module, a Donor base station (Donor eNB, DeNB) module, a routing switch module, an Evolved Packet Core (EPC) module (not shown), and the like.
Next, the relay base station/terminal device mode.
Fig. 4 is a schematic diagram of a portable central station in a relay base station and terminal device mode in a networking method according to an embodiment of the present application. Referring to fig. 4, when the first portable central station is in the relay base station and terminal equipment mode, the first portable central station is a single transmit-receive (1T 1receive, 1T1R) LTE base station and 1 relay terminal equipment (reply UE, RUE) of 1T 1R. Herein, the LTE base station may also be referred to as a relay eNB (ReNB).
Finally, dual terminal mode.
Fig. 5 is a schematic diagram of a portable central station in a dual-terminal mode in a networking method according to an embodiment of the present application. Referring to fig. 5, the first portable central station is two relay terminal equipments (ruis) of 1T1R when in the dual terminal mode.
In the embodiment of the application, the working mode of each portable central station can be flexibly selected according to the networking mode. When there is only one portable central station, the portable central station operates in the base station mode. In the following, how each portable central station performs networking will be described in detail when there are a plurality of portable central stations to be networked. For example, referring to fig. 6, fig. 6 is a flowchart of another networking method provided in the embodiment of the present application, where the embodiment includes:
201. the electronic equipment determines whether the number N of the portable central stations to be networked is an odd number, and if the number N is the odd number, the step 202 is executed; if N is an even number, step 205 is executed.
202. The electronic device determines whether the location of the first portable central station is at an odd position in the first sequence, and if the location is at an odd position, the step 203 is executed; if the step is located at the even position, step 204 is executed.
In a routine, the first sequence is substantially a sequence from 1 to N, the electronic device determines the position of the first portable central station, i.e. the position of the first portable central station in 1 to N, and if the position is located at an odd number, step 203 is executed; if the position is at an even position, step 204 is performed.
203. The electronic device determines the operating mode to be the host base station mode.
204. The electronic device determines that the operating mode is a dual-terminal mode.
205. The electronic device determines whether the location of the first portable central station is at an odd position in the first sequence, and if the location is at an odd position, the step 203 is executed; if the position is an even position, step 206 is performed.
206. The electronic device determines whether the location of the first portable central station is the last location in the first sequence, and if the location of the first portable central station is the last location in the first sequence, step 207 is executed; if the location of the first portable central station is not the last location in the first order, step 204 is performed.
207. The electronic equipment determines that the working mode is a relay base station and terminal equipment mode.
How to determine the operation mode in fig. 6 will be described in detail below using several examples. For example, see fig. 7-10.
Fig. 7 is a schematic networking diagram when 2 portable central stations to be networked in the networking method provided in the embodiment of the present application are configured. Referring to fig. 7, when there are 2 portable hubs to be networked, one of the portable hubs operates in a base station mode as a DeNB, and the other portable hub operates in a relay base station and terminal device mode. In this case, the mobile center operating in the relay base station/terminal equipment mode is referred to as an LTE in-band relay base station (RN). In order to maximize backhaul bandwidth, backhaul subframe allocation adopts allocation 4. For example, see fig. 8.
Fig. 8 is a schematic diagram illustrating a returned subframe ratio when the portable central station operates in the relay base station and terminal device mode in the networking method according to the embodiment of the present application. Referring to fig. 8, when a backhaul subframe is configured as a subframe of the Un port under Time Division Duplex (TDD), a subframe ratio is Config 4, that is, of 10 subframes included in a radio frame, the 3 rd subframe and the 8 th subframe are uplink (U) subframes, the 4 th subframe and the 9 th subframe are downlink subframes (downlink, D), and other subframes are not used but are reserved for the Un port.
Fig. 9 is a schematic networking diagram when there are 3 portable central stations to be networked in the networking method provided in the embodiment of the present application. Referring to fig. 9, when there are 3 portable central stations to be networked, two portable central stations at two ends, portable central station 1 and portable central station 3, operate in the base station mode, and the middle portable central station, i.e., portable central station 2, operates in the dual-terminal mode. One terminal unit at the portable central station 2 is connected to a higher portable central station (portable central station 1), the other terminal unit is connected to a lower portable central station (portable central station 3), and IP message intercommunication between the two terminal units is realized through route switching, so that a relay link is established between the higher portable central station and the lower portable central station. At this time, in order to avoid mutual interference and increase the rate of the relay link, the upper portable central station and the lower portable central station operate at different frequency points, such as f1 and f2 frequency points in fig. 9.
Referring to fig. 9, terminal units located in the coverage area of the portable central station 3 and on the right side of the portable central station 2 access the portable central station 3, and the portable central station 2 carries an identifier indicating that the portable central station 2 is a relay UE. When the terminal device wants to access the portable central station 1 and the portable central station 2, the terminal device accesses the portable central station 3, the EPC of the portable central station 3 identifies the relay UE from the accessed terminal devices, that is, the portable central station 2, and changes the next hop address to the portable central station 2. In this way, the portable center can transmit the data packet of the terminal device to the portable center 2.
In fig. 9, the above-described embodiment is described in detail by taking only the number of portable central stations as 3 as an example. However, the embodiments of the present application are not limited in sequence, and in other possible implementations, when more portable central stations are linearly networked, when the number of portable central stations is an odd number, the portable central stations may be networked in the manner shown in fig. 9.
Fig. 10 is a schematic networking diagram when there are 4 portable central stations to be networked in the networking method provided in the embodiment of the present application. Referring to fig. 10, when there are 4 portable central stations to be networked, the difference from fig. 9 is that: the operation mode of the last portable center, i.e., the portable center 4, is the relay base station and terminal equipment mode.
As can be seen from fig. 9 and 10: in the embodiment of the application, the multi-hop relay can be realized only by two frequency points f1 and f 2. Moreover, multi-hop relay is realized by combining one-hop in-band relay and terminal back-to-back out-of-band relay without end-to-end bandwidth reduction.
In the above embodiment, each portable central station to be networked can operate in absolute synchronization or relative synchronization. When operating in absolute synchronization, each portable central station acquires a synchronization signal from a Global Positioning System (GPS). In relative synchronization, a first portable central station acquires timing information from the upper portable central station, and a first terminal unit of the first portable central station transmits a synchronization signal on an uplink resource, which is a resource designated by the upper portable central station, so that the lower portable central station acquires the synchronization signal, wherein the synchronization signal carries the timing information.
For example, referring to fig. 9 and 10 again, in relative synchronization, the first portable central station may acquire a synchronization signal from the superior portable central station over the air interface. When the first portable central station operates in the dual-terminal mode, a terminal unit in the first portable central station that accesses the upper portable central station acquires timing information using a Device-to-Device (D2D) function, and transmits a synchronization signal carrying the timing information on an uplink resource specified by the upper central station, for example, 6 Physical Resource Blocks (PRBs) specified by the upper central station on a single-edge (sidelink) synchronization subframe. The lower portable central station works in a base station mode, and firstly searches for a D2D synchronous signal on a specific PRB of a frequency point of the upper portable central station. After obtaining the clock synchronization, the lower portable central station establishes a cell on its own frequency point, works in the same uplink and downlink time slot ratio as the upper portable central station, meanwhile, continuously receives the D2D synchronization signal on the frequency point of the upper portable central station on the uplink time slot, and saves the synchronization with the upper portable central station.
In this embodiment, the timing is obtained through a GPS method, or obtained through a D2D method from an air interface.
