Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular to a base station adaptive channel synchronization system, method, and base station. Background Art

[0002] Time Division Multiple Access (TDMA) is a network communication technology. Time Division Multiple Access technology divides time into several non-overlapping time periods (frames), and then divides each frame into several non-overlapping time slots (channels). Each time slot is allocated to a different user for data transmission or voice calls, allowing multiple users to use the same frequency in different time slices (time slots). In this way, multiple users can share the same transmission medium, such as radio frequency. However, within a specific frequency band, the number of available channels is limited, and each channel has a certain bandwidth. When multiple base stations are running at the same time, they will occupy these limited channel resources. If the channel allocation between base stations is unreasonable or there is overlap, it will cause channel interference.

[0003] When there are multiple independently operating base stations in a space, each base station will select its own channel for communication. If these base stations select the same or similar channels, their signals will overlap in the same frequency band, causing mutual interference. This interference will reduce the communication quality and even cause communication interruption.

[0004] And due to channel overlap and communication conflicts, the originally available channels may not be effectively utilized in actual use. This means that although there are multiple available channels in theory, in practice the number of channels that can be effectively utilized is greatly reduced due to interference and conflicts. Finally, when multiple base stations interfere with each other, they may try to solve the problem by increasing the transmission power or changing the frequency. However, these measures often further aggravate the interference, forming a vicious cycle. Summary of the invention

[0005] The embodiments of the present invention provide an adaptive channel synchronization system, method, and base station for a base station. By synchronizing the channels of several base stations in a space, channel overlap and communication conflicts among multiple base stations are effectively avoided, and the overall number of available channels in the space is effectively increased.

[0068] See also Figure 1 , is a structural diagram of an adaptive channel synchronization system of a base station provided by an embodiment of the present invention, comprising: a first base station 01 and a plurality of second base stations 02;

[0069] The first base station 01 is used to occupy an idle channel as a first channel for its own data transmission when starting;

[0070] Conduct synchronous signal search within its own spatial range;

[0071] When no synchronization signal is found, the base station uses itself as a synchronization source base station, generates a first synchronization signal, and then broadcasts the first synchronization signal in the first channel;

[0072] In a preferred embodiment of the present invention, Figure 3 As shown, after Base1 (the first base station) is started, it searches for surrounding signals to confirm whether there is a working Base. If there is no other Base, Base1 starts normally and broadcasts in its own dummy (first channel), declaring itself as the synchronization source, and uses its RFP I as an identifier (recorded as RFP I 1). It should be noted that the first base station and the second base station are only used to distinguish whether it is the first base station started within the spatial range, that is, in this embodiment, the first base station started within the limited spatial range is called the first base station, and the base station started subsequently is called the second base station.

[0073] The plurality of said second base stations 02 are used to occupy an idle channel as a second channel for their own data transmission when starting;

[0074] Conduct synchronous signal search within its own spatial range;

[0075] When the first synchronization signal is searched, the second channel is synchronized with the first channel, and the first synchronization signal is broadcast in the second channel, so as to form a first channel synchronization tree with the first base station 01.

[0076] In a preferred embodiment of the present invention, Figure 4 As shown, after Base1 is started, Base2 (the second base station) is started and also searches for surrounding signals first. When Base2 finds that Base1 is already a synchronization source and confirms that the first synchronization signal meets the minimum synchronization signal strength requirement, Base2 synchronizes to Base1 and broadcasts that the synchronization source is Base1 in its own dummy (second channel), using Base1's RFP I as an identifier. After synchronization, the channels of Base1 and Base2 can be aligned.

[0077] It should be further explained that, if Base3, Base4, Base5, etc. and other second base stations 02 are started subsequently, they can search for Base1 or Base2, and confirm that the first synchronization signal meets the minimum synchronization signal strength requirement, Base3, Base4, Base5, etc. and other second base stations 02 are all synchronized to Base1, and broadcast the synchronization source as Base1 in their own dummy, use Base1's RFP I as an identifier, and join the second base stations 02 with Base1 as the synchronization source. Figure 5 The synchronization tree shown.

[0078] Preferably, after broadcasting the first synchronization signal in the second channel, the second base station 02 is further configured to:

[0079] Conduct synchronous signal search within its own spatial range;

[0080] When a second synchronization signal is searched, the second synchronization signal is compared with the first synchronization signal to determine a target synchronization signal;

[0081] When it is determined that the target synchronization signal is a second synchronization signal, the second channel is synchronized with a target channel corresponding to the second synchronization signal, and the second synchronization signal is broadcasted in the second channel.

[0082] Preferably, the first base station 01 generates a first synchronization signal, including:

[0083] generating the first synchronization signal according to its own first radio frequency identification number;

[0084] The second base station 02 compares the second synchronization signal with the first synchronization signal to determine a target synchronization signal, including:

[0085] Determine a first radio frequency identification number of the first base station 01 according to the first synchronization signal, and determine a second radio frequency identification number of a synchronization source base station corresponding to the second synchronization signal according to the second synchronization signal;

[0086] comparing the numerical values ​​of the first radio frequency identification number and the second radio frequency identification number;

[0087] When the first radio frequency identification number is smaller than the second radio frequency identification number, determining the first synchronization signal as a target synchronization signal;

[0088] When the first radio frequency identification number is greater than the second radio frequency identification number, the second synchronization signal is determined as a target synchronization signal.

[0089] In a preferred embodiment of the present invention, Figure 6 As shown in FIG. 1 , when Base11 and Base12 are started at a distance, a synchronization tree is generated again because the synchronization signal of the synchronization tree of the first channel cannot be searched. However, Figure 7 As shown in the figure, as the number of Bases added to the two synchronization trees increases, the two synchronization trees will be adjacent to and cross each other.

[0090] Therefore, in order to prevent the base stations on the two synchronization trees from overlapping channels and interfering with each other, in this embodiment, each Base, while maintaining synchronization, continues to search for the existence of Bases in other synchronization trees. If so, the RFPI of the synchronization source is compared and added to a group of synchronization trees with a smaller RFPI if the basic synchronization signal requirements are met. It can be understood that, if Figure 7 As shown in the figure, when the synchronization source of Base13 becomes Base1, Base11 will detect the synchronization signal of Base1 from the channel of Base13, and then compare the RFPI of the synchronization source, and then join the synchronization tree of Base1 with smaller RFPI, and so on, gradually update, and finally, all Bases will join a synchronization tree, forming the following Figure 8 The channel synchronization tree shown in Figure 1 is used to align all Base channels.

[0091] It is understandable that, in addition to comparing RFPI, other synchronization rules may also be used to determine a synchronization source, such as comparing signal strength, etc. By defining a synchronization rule, all devices can quickly build a synchronization tree according to the rule.

[0092] Preferably, the second base station 02, after synchronizing the second channel with the first channel corresponding to the first synchronization signal, is further configured to:

[0093] When detecting that the first base station 01 is powered off, searching for synchronization signals within the spatial range where the first base station 01 is located;

[0094] When no new third synchronization signal is searched, the base station uses itself as a synchronization source base station, uses its second channel as a synchronization channel, generates a third synchronization signal, and then broadcasts the third synchronization signal in the synchronization channel;

[0095] When a new third synchronization signal is searched, its own second channel is synchronized with the synchronization channel corresponding to the third synchronization signal, and the third synchronization signal is broadcasted in the second channel.

[0096] In a preferred embodiment of the present invention, Fig. 9 As shown, when the synchronization source Base1 is powered off or abnormal, the lower-level Base is used as the synchronization source, splitting to generate multiple synchronization trees, and the multiple synchronization trees grow and merge separately. It should be noted that the synchronization source is not necessarily the base station with the smallest RFP I as the synchronization source. After the base station of the original root node is powered off or abnormal, the other branch nodes will adapt to become the new root node or the child nodes under the new root node.

[0097] Preferably, the first base station 01 is further configured to reoccupy an idle channel as a fourth channel for its own data transmission after power failure and restart;

[0098] Conduct synchronous signal search within its own spatial range;

[0099] When the third synchronization signal is searched, the fourth channel is synchronized with the synchronization channel corresponding to the third synchronization signal, and the third synchronization signal is broadcasted in the fourth channel.

[0100] In a preferred embodiment of the present invention, Fig.10 As shown, if the original synchronization source Base1 is powered on again, it only needs to simply search the current synchronization tree, compare which signal is stronger, and add it to the synchronization tree.

[0101] This embodiment provides an adaptive channel synchronization system for a base station, including: a first base station and several second base stations; after being started, the first base station searches for a synchronization signal within the spatial range where it is located. When no synchronization signal is found, it indicates that there is only one base station within the spatial range. Therefore, the first base station uses itself as a synchronization source base station, generates a first synchronization signal, and then broadcasts the first synchronization signal in its own first channel. When a second base station is started within the spatial range later, the first synchronization signal can be searched. At this time, the second base station uses the first base station as a synchronization source, synchronizes the second channel with the first channel, and broadcasts the first synchronization signal in the second channel to construct a first channel synchronization tree with the first base station as the synchronization source. It can be understood that when many second base stations appear later, the first synchronization signal can be detected from the first channel or several first channels, and then join the first channel synchronization tree. Therefore, in this embodiment, the several second base stations that are subsequently started all use the first started first base station as the synchronization source, and synchronize the channels of several base stations in the space, so as to avoid each base station selecting the same or similar channels, resulting in overlapping and mutual interference of signals in the same frequency band, and ultimately causing communication interruption, and effectively increase the number of overall available channels in the same space.

[0102] See also Figure 2 , is a flow chart of an adaptive channel synchronization method of a base station provided by an embodiment of the present invention, comprising:

[0103] S1, when starting up, occupies an idle channel as the second channel for its own data transmission;

[0104] S2. Search for synchronous signals within the space where the user is located;

[0105] S3. When the first synchronization signal is searched, synchronize the second channel with the first channel corresponding to the first synchronization signal, and broadcast the first synchronization signal in the second channel, so that the first base station corresponding to the first synchronization signal forms a first channel synchronization tree.

[0106] Preferably, after broadcasting the first synchronization signal in the second channel, the method further includes:

[0107] S4, searching for synchronous signals within the space where the user is located;

[0108] S5. When a second synchronization signal is searched, compare the second synchronization signal with the first synchronization signal to determine a target synchronization signal;

[0110] S51.

[0111] S52: compare the numerical values ​​of the first radio frequency identification number and the second radio frequency identification number;

[0112] S53: when the first radio frequency identification number is smaller than the second radio frequency identification number, determining the first synchronization signal as a target synchronization signal;

[0114] S6. When it is determined that the target synchronization signal is a second synchronization signal, synchronize the second channel with a target channel corresponding to the second synchronization signal, and broadcast the second synchronization signal in the second channel.

[0118] S9. When a new third synchronization signal is searched, synchronize its own second channel with the synchronization channel corresponding to the third synchronization signal, and broadcast the third synchronization signal in the second channel.

[0119] Another preferred embodiment of the present invention provides a base station, comprising a processor, a memory, and a computer program stored in the memory and configured to be executed by the processor, wherein when the processor executes the computer program, it implements an adaptive channel synchronization method for a base station as described in any one of the above embodiments.

[0120] The base station may be a computing device such as a desktop computer, a notebook, a PDA, a cloud server, etc. The base station may include, but is not limited to, a processor and a memory.

[0121] The processor may be a central processing unit (CPU), other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor or any conventional processor, etc. The processor is the control center of the base station, and uses various interfaces and lines to connect various parts of the entire base station.

[0122] The memory can be used to store the computer program, and the processor realizes various functions of the base station by running or executing the computer program stored in the memory and calling the data stored in the memory. The memory can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, at least one application required for a function, etc.; the data storage area can store data created according to the use of the mobile phone, etc. In addition, the memory can include a high-speed random access memory, and can also include a non-volatile memory, such as a hard disk, a memory, a plug-in hard disk, a smart memory card (Smart Med ia Card, SMC), a secure digital (Secure Digital, SD) card, a flash card (Flash Card), at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.
