Description
本發明係關於一種無線接入網路系統。The present invention relates to a wireless access network system.
現有的5G專網佈建方式，都是使用一組基站連接多組天線，以天線佈滿場域的形式達到完全覆蓋。同時，場域內佈建多組使用者設備連結終端機台，終端機台傳輸資料時會透過使用者設備，使用者設備再將資料經由天線傳輸至基站，基站再將資料傳輸至核心網路，核心網路最後將資料傳輸至控制中心。Existing 5G private network deployment methods use a single base station connected to multiple antennas, with antennas deployed throughout the site to achieve complete coverage. Simultaneously, multiple user devices (UEs) are deployed within the site and connected to end devices. Data from the end devices passes through the UEs, which then transmit the data via the antennas to the base station. The base station then transmits the data to the core network, which then transmits the data to the control center.
然而，當基站因不可控因素導致無法工作時，會進一步導致場域內的使用者設備失去連線、無法傳輸資料。換言之，當基站的穩定度不高時，必然有機會發生資料傳輸中斷的問題。However, when a base station fails due to uncontrollable factors, it can cause user devices within the area to lose connectivity and be unable to transmit data. In other words, when base station stability is low, data transmission interruptions are inevitable.
鑒於上述，本發明提供一種解決上述問題的無線接入網路系統。In view of the above, the present invention provides a wireless access network system that solves the above problems.
依據本發明一實施例的無線接入網路系統，包括：至少一第一無線電單元以及至少一第二無線電單元。所述至少一第一無線電單元具有第一頻帶，所述至少一第二無線電單元具有第二頻帶，其中第一頻帶的頻率範圍與第二頻帶的頻率範圍彼此不重疊，第一頻帶在區域的第一覆蓋範圍與第二頻帶在該區域的第二覆蓋範圍彼此部分重疊。According to one embodiment of the present invention, a wireless access network system includes at least one first radio unit and at least one second radio unit. The at least one first radio unit has a first frequency band, and the at least one second radio unit has a second frequency band. The frequency range of the first frequency band and the frequency range of the second frequency band do not overlap, and a first coverage range of the first frequency band in a region partially overlaps with a second coverage range of the second frequency band in the same region.
根據以上一或多個實施例所述的無線接入網路系統，藉由多頻段的覆蓋範圍重疊設計，當其中一個頻段的無線電單元（或基站）因不可控因素無法正常工作時，可藉由另一個頻段的無線電單元（或基站）作為備援，避免使用者設備完全失去無線訊號連線，達到區域內的連線高可用性的目的。並且，由於第一頻帶與第二頻帶的範圍不同，故不會產生同頻訊號干擾的現象。透過上述多頻帶覆蓋機制，可提供使用者設備穩定的無線訊號品質。因此，可大幅降低終端機台及使用者設備在傳輸資料的過程中，發生傳輸中斷的機率。According to the wireless access network system described in one or more of the above embodiments, through a multi-band overlapping coverage design, if a radio unit (or base station) in one frequency band fails to operate properly due to uncontrollable factors, a radio unit (or base station) in another frequency band can be used as a backup, preventing user devices from completely losing wireless signal connectivity and achieving high connection availability within the area. Furthermore, because the first and second frequency bands have different ranges, co-frequency signal interference is prevented. This multi-band coverage mechanism provides user devices with stable wireless signal quality, significantly reducing the probability of transmission interruptions during data transmission between terminal devices and user devices.

Based on the disclosure, patent application scope, and drawings in this specification, anyone skilled in the relevant art can easily understand the relevant objectives and advantages of the present invention. The following examples are intended to further illustrate the concepts of the present invention in detail and are not intended to limit the scope of the present invention in any way.
請參考圖1，其中圖1係依據本發明一實施例所繪示的無線接入網路系統的方塊圖。如圖1所示，無線接入網路系統10包括使用者設備100、多個第一無線電單元（radio unit）101及102，以及多個第二無線電單元201及202。圖1示例性示出兩個第一無線電單元及兩個第二無線電單元，但第一無線電單元及第二無線電單元各自的數量亦可等於一或大於二，且第一無線電單元及第二無線電單元的數量可彼此相同或相異，本發明不予以限制。Please refer to Figure 1, which is a block diagram of a wireless access network system according to an embodiment of the present invention. As shown in Figure 1, the wireless access network system 10 includes a user equipment 100, multiple first radio units 101 and 102, and multiple second radio units 201 and 202. Figure 1 illustrates two first radio units and two second radio units, but the number of first radio units and second radio units can be equal to one or greater than two, and the number of first radio units and second radio units can be the same or different, and the present invention is not limited thereto.
使用者設備100可為客戶終端設備（customer premise equipment，CPE）。進一步而言，當無線接入網路系統10是應用於例如工廠或辦公室等環境中，使用者設備100可為終端機台（例如，加工機台）、桌上型電腦等位於固定位置的固定式設備。使用者設備100為選擇性設置的元件。User equipment 100 may be customer premises equipment (CPE). Furthermore, when wireless access network system 10 is used in an environment such as a factory or office, user equipment 100 may be a fixed device located in a fixed location, such as a terminal machine (e.g., a processing machine) or a desktop computer. User equipment 100 is an optional component.
第一無線電單元101及102可為部署在天線附近或整合到天線中的無線電單元。第二無線電單元201及202可為部署在相同的天線附近或整合到相同的天線中的無線電單元。第一無線電單元101及102以及第二無線電單元201及202皆可將發送到天線與從天線發出的無線電訊號轉換為數位訊號進行傳輸。First radio units 101 and 102 can be deployed near or integrated into an antenna. Second radio units 201 and 202 can be deployed near or integrated into the same antenna. Both first radio units 101 and 102 and second radio units 201 and 202 can convert radio signals sent to and from the antenna into digital signals for transmission.
第一無線電單元101及102的每一者具有第一頻帶，第二無線電單元201及202的每一者具有第二頻帶。第一頻帶的頻率範圍與第二頻帶的頻率範圍彼此不重疊。舉例而言，第一頻帶的頻率範圍可為4600兆赫茲（MHz）到4700MHz，第二頻帶的頻率範圍可為4800MHz到4900MHz。Each of the first radio units 101 and 102 has a first frequency band, and each of the second radio units 201 and 202 has a second frequency band. The frequency range of the first frequency band and the frequency range of the second frequency band do not overlap. For example, the frequency range of the first frequency band may be 4600 MHz to 4700 MHz, and the frequency range of the second frequency band may be 4800 MHz to 4900 MHz.
並且，第一頻帶在一區域的第一覆蓋範圍與第二頻帶在該區域的第二覆蓋範圍彼此部分重疊。第一覆蓋範圍及第二覆蓋範圍可視為天線的無線訊號收發範圍。請一併參考圖1及圖2，其中圖2係依據本發明一實施例所繪示的各頻帶的覆蓋範圍的示意圖。在圖2中，較粗的虛線係用於呈現第一頻帶的覆蓋範圍，較細的虛線係用於呈現第二頻帶的覆蓋範圍。Furthermore, the first coverage area of the first frequency band in an area partially overlaps with the second coverage area of the second frequency band in the same area. The first coverage area and the second coverage area can be considered the wireless signal transmission and reception range of the antenna. Please refer to Figures 1 and 2 together, with Figure 2 being a schematic diagram illustrating the coverage areas of various frequency bands according to an embodiment of the present invention. In Figure 2, the thicker dashed line represents the coverage area of the first frequency band, and the thinner dashed line represents the coverage area of the second frequency band.
圖2示出12個第一覆蓋範圍A1到A12及6個第二覆蓋範圍B1到B6，其中圖2示出的第一覆蓋範圍及第二覆蓋範圍的數量僅為示例，本發明不予以限制。對應於圖1，第一覆蓋範圍A1可對應於第一無線電單元101的覆蓋範圍，第一覆蓋範圍A2可對應於第一無線電單元102的覆蓋範圍。相似地，第二覆蓋範圍B1可對應於第二無線電單元201的覆蓋範圍，第二覆蓋範圍B2可對應於第B無線電單元202的覆蓋範圍。換言之，在圖2的例子中，無線接入網路系統可有12個第一無線電單元及6個第二無線電單元。FIG2 shows 12 first coverage areas A1 through A12 and 6 second coverage areas B1 through B6. The number of first and second coverage areas shown in FIG2 is merely an example and is not intended to limit the present invention. With reference to FIG1 , first coverage area A1 may correspond to the coverage area of first radio unit 101, and first coverage area A2 may correspond to the coverage area of first radio unit 102. Similarly, second coverage area B1 may correspond to the coverage area of second radio unit 201, and second coverage area B2 may correspond to the coverage area of B-th radio unit 202. In other words, in the example of FIG2 , the wireless access network system may have 12 first radio units and 6 second radio units.
如圖2所示，在區域R中，第一覆蓋範圍A1與第二覆蓋範圍B1彼此部分重疊，第一覆蓋範圍A2與第二覆蓋範圍B1彼此部分重疊，以及第一覆蓋範圍A2與第二覆蓋範圍B2彼此部分重疊，其他第一覆蓋範圍及第二覆蓋範圍的佈置方式同理，不再於此贅述。換言之，每個第二覆蓋範圍可用於覆蓋第一覆蓋範圍的一部分及第一覆蓋範圍未涵蓋的部分。區域R可為如上述的工廠或辦公室等環境。As shown in Figure 2, in region R, the first coverage area A1 partially overlaps with the second coverage area B1, the first coverage area A2 partially overlaps with the second coverage area B1, and the first coverage area A2 partially overlaps with the second coverage area B2. The layout of the other first and second coverage areas is similar and will not be further described here. In other words, each second coverage area can be used to cover a portion of the first coverage area and portions not covered by the first coverage area. Region R can be an environment such as the factory or office mentioned above.
並且，第一無線電單元101的第一覆蓋範圍A1與第一無線電單元102的第一覆蓋範圍A2彼此鄰接且不重疊，第二無線電單元201的第二覆蓋範圍B2與第二無線電單元202的第二覆蓋範圍B2彼此鄰接且不重疊。圖2示出第一覆蓋範圍鄰接於另一第一覆蓋範圍，及第二覆蓋範圍鄰接於另一第二覆蓋範圍，但本發明不限於圖2所示的鄰接設計，惟透過此鄰接設計，可使用較少的無線電單元形成涵蓋區域R的覆蓋範圍。Furthermore, the first coverage area A1 of the first radio unit 101 and the first coverage area A2 of the first radio unit 102 are adjacent to each other and do not overlap, and the second coverage area B2 of the second radio unit 201 and the second coverage area B2 of the second radio unit 202 are adjacent to each other and do not overlap. FIG2 shows that a first coverage area is adjacent to another first coverage area, and a second coverage area is adjacent to another second coverage area. However, the present invention is not limited to the adjacent design shown in FIG2. However, through this adjacent design, a coverage area covering area R can be formed using fewer radio units.
另外，使用者設備100可設置於第一覆蓋範圍與第二覆蓋範圍之間的重疊部分內，即第一無線電單元的覆蓋範圍與第二無線電單元的覆蓋範圍的交界處。以圖2為例，第一覆蓋範圍A1與第二覆蓋範圍B1之間具有重疊部分C1，使用者設備100可位於重疊部分C1內。進一步來說，使用者設備100可位於固定位置。Alternatively, the user equipment 100 can be placed within the overlapping portion between the first and second coverage areas, i.e., the boundary between the coverage areas of the first and second radio units. For example, in Figure 2 , there is an overlapping portion C1 between the first and second coverage areas A1 and B1, and the user equipment 100 can be located within the overlapping portion C1. Furthermore, the user equipment 100 can be located in a fixed position.
另外，圖2示例性地將覆蓋範圍繪示為圓形，且每個覆蓋範圍具有相同尺寸，但覆蓋範圍亦實現為不同形狀且可有不同尺寸。2 exemplarily illustrates the coverage areas as circles, and each coverage area has the same size, but the coverage areas may also be implemented in different shapes and sizes.
根據以上一或多個實施例所述的無線接入網路系統，藉由多頻段的覆蓋範圍重疊設計，當其中一個頻段的無線電單元（或基站）因不可控因素無法正常工作時，可藉由另一個頻段的無線電單元（或基站）作為備援，避免使用者設備完全失去無線訊號連線，達到區域內的連線高可用性的目的。並且，由於第一頻帶與第二頻帶的範圍不同，故不會產生同頻訊號干擾的現象。透過上述多頻帶覆蓋機制，可提供使用者設備穩定的無線訊號品質。因此，可大幅降低終端機台及使用者設備在傳輸資料的過程中，發生傳輸中斷的機率。According to the wireless access network system described in one or more of the above embodiments, through a multi-band overlapping coverage design, if a radio unit (or base station) in one frequency band fails to operate properly due to uncontrollable factors, a radio unit (or base station) in another frequency band can be used as a backup, preventing user devices from completely losing wireless signal connectivity and achieving high connection availability within the area. Furthermore, because the first and second frequency bands have different ranges, co-frequency signal interference is prevented. This multi-band coverage mechanism provides user devices with stable wireless signal quality, significantly reducing the probability of transmission interruptions during data transmission between terminal devices and user devices.
此外，第一頻帶及第二頻帶中具有較低的頻率範圍的一者可有較大的覆蓋範圍。以圖2為例，第一頻帶的頻率範圍低於第二頻帶的頻率範圍，圖2中所示的12個第一覆蓋範圍的總面積可大於圖2中所示的6個第二覆蓋範圍的總面積。因此，使用者設備100可用於在第一無線電單元及第二無線電單元皆正常運作時，連接第一無線電單元。舉例而言，假設使用者設備100位於重疊部分C1，且第一覆蓋範圍A1對應的第一無線電單元及第二覆蓋範圍B1對應的第二無線電單元皆正常運作時，使用者設備100可連接至第一覆蓋範圍A1對應的第一無線電單元。換言之，在使用者設備100可偵測到的多個正常運作無線電單元中，使用者設備100可優先連接於有較低頻率範圍且訊號強度最強的無線電單元。因此，當使用者設備100在第一頻帶所覆蓋的範圍內且對應的第一無線電單元正常運作時，使用者設備100可優先透過第一無線電單元的網路進行資料傳輸。此時，第二無線電單元未連接於使用者設備100，第二無線電單元可進入待機備援狀態。Furthermore, the one with the lower frequency range between the first and second frequency bands can have a larger coverage area. For example, in Figure 2 , the frequency range of the first frequency band is lower than the frequency range of the second frequency band. Therefore, the total area of the 12 first coverage areas shown in Figure 2 can be larger than the total area of the 6 second coverage areas shown in Figure 2 . Therefore, the user equipment 100 can be connected to the first radio unit when both the first radio unit and the second radio unit are operating normally. For example, assuming that user device 100 is located in overlapping portion C1, and both the first radio unit corresponding to first coverage area A1 and the second radio unit corresponding to second coverage area B1 are operating normally, user device 100 may connect to the first radio unit corresponding to first coverage area A1. In other words, among multiple normally operating radio units that user device 100 can detect, user device 100 may preferentially connect to the radio unit with a lower frequency range and the strongest signal strength. Therefore, when user device 100 is within the coverage area of the first frequency band and the corresponding first radio unit is operating normally, user device 100 may preferentially transmit data through the network of the first radio unit. At this time, the second radio unit is not connected to the user equipment 100, and the second radio unit may enter a standby backup state.
於另一實施例中，使用者設備100設置於重疊部分C1內，且使用者設備100可用於由低至高進行頻帶掃描，且連接於掃描到的第一無線電單元或第二無線電單元。換言之，使用者設備100可由低至高進行頻帶掃描，以連接到正常運作且有最低頻帶的無線電單元。因此，當使用者設備100未掃描到如圖2所示的12個第一覆蓋範圍所對應的第一無線電單元中的任一者而掃描到第二無線電單元時，使用者設備100可連接於該第二無線電單元。舉例而言，假設使用者設備100位於重疊部分C1，且使用者設備100無法偵測到第一覆蓋範圍A1的第一無線電單元101而可偵測到第二覆蓋範圍B1對應的第二無線電單元201時，使用者設備100可連接於第二無線電單元201。進一步而言，當第一無線電單元101因不可控因素無法正常工作時，會導致使用者設備100失去連線、無法傳輸資料。此時，因場域中還有處於備援狀態的第二無線電單元201能夠提供連線服務，且使用者設備100處於第二無線電單元201的訊號覆蓋範圍（例如，第二覆蓋範圍B1）中，使用者設備100在失去與第一無線電單元101的連線後，會自動掃描環境中其他可連線的頻帶，當使用者設備100掃描到第二無線電單元201的頻帶後，使用者設備100會向第二無線電單元201發起連線與註冊行為，進而恢復資料傳輸工作。In another embodiment, the user device 100 is positioned within the overlapping portion C1 and can be configured to scan the frequency band from low to high and connect to the scanned first radio unit or second radio unit. In other words, the user device 100 can scan the frequency band from low to high to connect to the properly functioning radio unit with the lowest frequency band. Therefore, if the user device 100 does not scan any of the 12 first radio units corresponding to the first coverage areas shown in FIG. 2 and scans a second radio unit, the user device 100 can connect to the second radio unit. For example, if user equipment 100 is located in overlapping area C1 and cannot detect first radio unit 101 in first coverage area A1 but can detect second radio unit 201 corresponding to second coverage area B1, user equipment 100 can connect to second radio unit 201. Furthermore, if first radio unit 101 malfunctions due to uncontrollable factors, user equipment 100 may lose connection and be unable to transmit data. At this point, because the second radio unit 201 in backup mode is available in the environment and can provide connection services, and the user device 100 is within the signal coverage range of the second radio unit 201 (for example, the second coverage range B1), after losing connection with the first radio unit 101, the user device 100 automatically scans for other connectable frequency bands in the environment. Once the user device 100 finds the frequency band of the second radio unit 201, it initiates a connection and registration process with the second radio unit 201, thereby resuming data transmission.
當第一無線電單元101恢復正常運作時，第一無線電單元101可進入待機備援狀態，使用者設備100繼續使用第二無線電單元201提供的連線功能。另外，使用者設備100亦可定期或不定期地掃描環境中其他可連線的頻帶，故當使用者設備100掃描到第一無線電單元101的頻帶時，使用者設備100可切換連接至第一無線電單元101，此時第二無線電單元201進入待機備援狀態。也就是說，當使用者設備在原頻帶失效時，可搭配偵測機制掃描環境中可用頻帶並自動切換至新頻帶；當原頻帶恢復正常運作時，使用者設備會切換至原頻帶並續行資料傳輸工作。When the first radio unit 101 resumes normal operation, it may enter a standby backup state, and the user device 100 may continue to use the connection function provided by the second radio unit 201. Furthermore, the user device 100 may periodically or irregularly scan for other connectable frequency bands in the environment. Therefore, when the user device 100 detects the frequency band of the first radio unit 101, the user device 100 may switch its connection to the first radio unit 101, at which point the second radio unit 201 enters a standby backup state. That is, when a user device experiences a failure in the original frequency band, the detection mechanism can scan the available frequency bands in the environment and automatically switch to a new frequency band. When the original frequency band resumes normal operation, the user device will switch back to the original frequency band and continue data transmission.
請參考圖3，其中圖3係依據本發明另一實施例所繪示的無線接入網路系統的方塊圖。如圖3所示，無線接入網路系統20包括使用者設備100、多個第一無線電單元101及102、多個第二無線電單元201及202、第一集線器301、第二集線器302、第一基帶單元（baseband unit，BBU）401、第二基帶單元402以及核心網路500。Please refer to Figure 3, which is a block diagram of a wireless access network system according to another embodiment of the present invention. As shown in Figure 3, the wireless access network system 20 includes a user equipment 100, multiple first radio units 101 and 102, multiple second radio units 201 and 202, a first hub 301, a second hub 302, a first baseband unit (BBU) 401, a second baseband unit 402, and a core network 500.
第一集線器301及第二集線器302可為遠端無線電單元集線器（remote radio unit hub，rHub）。第一集線器301經由第一光纖OF1連接於第一無線電單元101及102，第二集線器302經由第二光纖OF2連接於第二無線電單元201及202。The first hub 301 and the second hub 302 may be remote radio unit hubs (rHubs). The first hub 301 is connected to the first radio units 101 and 102 via a first optical fiber OF1, and the second hub 302 is connected to the second radio units 201 and 202 via a second optical fiber OF2.
第一基帶單元401連接於第一集線器301，第二基帶單元402連接於第二集線器302，且第一基帶單元401及第二基帶單元402連接於核心網路500。核心網路500可為5G核心網路。The first baseband unit 401 is connected to the first hub 301, the second baseband unit 402 is connected to the second hub 302, and the first baseband unit 401 and the second baseband unit 402 are connected to the core network 500. The core network 500 may be a 5G core network.
假設第一無線電單元101為使用者設備100所連接的無線電單元，則第一基帶單元401可從核心網路500接收數位訊號，將數位訊號經由第一集線器301及第一光纖OF1輸出至第一無線電單元101。另外，使用者設備100輸出的訊號亦可經由第一無線電單元101及第一光纖OF1輸出至第一集線器301，再由第一集線器301將訊號透過第一基帶單元401輸出至核心網路500。當使用者設備100是連接於第二無線電單元時，對應的運作方式可與上述的第一無線電單元101、第一集線器301、第一基帶單元401及核心網路500相同，於此不再贅述。Assuming that the first radio unit 101 is the radio unit to which the user equipment 100 is connected, the first baseband unit 401 can receive digital signals from the core network 500 and output the digital signals to the first radio unit 101 via the first hub 301 and the first optical fiber OF1. Alternatively, the signal output by the user equipment 100 can also be output to the first hub 301 via the first radio unit 101 and the first optical fiber OF1, and then the first hub 301 outputs the signal to the core network 500 via the first baseband unit 401. When the user equipment 100 is connected to a second radio unit, the corresponding operation is the same as the first radio unit 101, the first hub 301, the first baseband unit 401, and the core network 500 described above, and will not be further described here.
根據以上一或多個實施例所述的無線接入網路系統，藉由多頻段的覆蓋範圍重疊設計，當其中一個頻段的無線電單元（或基站）因不可控因素無法正常工作時，可藉由另一個頻段的無線電單元（或基站）作為備援，避免使用者設備完全失去無線訊號連線，達到區域內的連線高可用性的目的。並且，由於第一頻帶與第二頻帶的範圍不同，故不會產生同頻訊號干擾的現象。透過上述多頻帶覆蓋機制，可提供使用者設備穩定的無線訊號品質。因此，可大幅降低終端機台及使用者設備在傳輸資料的過程中，發生傳輸中斷的機率。According to the wireless access network system described in one or more of the above embodiments, through a multi-band overlapping coverage design, if a radio unit (or base station) in one frequency band fails to operate properly due to uncontrollable factors, a radio unit (or base station) in another frequency band can be used as a backup, preventing user devices from completely losing wireless signal connectivity and achieving high connection availability within the area. Furthermore, because the first and second frequency bands have different ranges, co-frequency signal interference is prevented. This multi-band coverage mechanism provides user devices with stable wireless signal quality, significantly reducing the probability of transmission interruptions during data transmission between terminal devices and user devices.
