Description

Technical Field

[0001] The present invention relates to the field of communications, and in particular to a spectrum sharing method and device, a base station and a network controller. Background Art

[0002] With the deep integration of new-generation information technology represented by mobile Internet, Internet of Things, and cloud computing with traditional industries, the application characteristics of radio technology in broadband, ubiquitous, mobile, and multi-standard are becoming increasingly obvious. The multi-standard feature refers to the coexistence of multiple network standards in wireless networks, that is, multiple network standards need to occupy frequency bands in the radio spectrum, and spectrum resources are limited. The frequency bands occupied by 2G networks and 3G networks with the best coverage performance are non-renewable resources in the radio frequency bands. Therefore, the deployment of 5G networks has become an urgent issue for major operators today.

[0003] The industry currently has the following solutions: First, spectrum refarming, that is, directly shutting down the 2G / 3G network and updating the corresponding frequency band to the 5G network. However, considering that 70% of the voice services in the entire network are still carried on the 2G / 3G network, this method is difficult to implement; second, the static spectrum allocation method is adopted, that is, 2G / 3G / 4G / 5G each occupies a part of the spectrum. Considering that in the early stage of wireless network development, the network standards dominated by 2G / 3G / 4G basically occupied all the low-frequency bands in the radio spectrum, and the network coverage capability of the high-frequency band was weak. Therefore, if continuous coverage of the 5G network is to be achieved, more sites need to be set up, and the cost is also greater. In addition, due to limited spectrum resources, this division method cannot fully play the advantage of the large bandwidth of the 5G network. Summary of the invention

[0032] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0033] A first embodiment of the present invention relates to a spectrum sharing method, such as Figure 1 As shown, the base station of the first network mode that mainly carries data services, after learning the current spectrum occupancy of the second network mode that mainly carries voice services, performs spectrum resource scheduling on the currently available spectrum resources according to the current spectrum occupancy, specifically including:

[0034] Step 101: Receive first notification information sent by a network controller of a second network standard.

[0035] Step 102: Acquire currently available spectrum resources according to the first notification information.

[0036] Step 103: Perform spectrum resource scheduling according to currently available spectrum resources.

[0037] Among them, the resources used to carry data services in the first network standard are greater than the resources used to carry voice services, and the resources used to carry voice services in the second network standard are greater than the resources used to carry data services. Since the load of voice services varies in different time periods, the first network standard can occupy the spectrum resources currently not occupied by the second network standard when the load of voice services is low, so as to improve the utilization rate of the spectrum. The implementation details of the spectrum sharing method of this implementation method are described in detail below. The following content is only the implementation details provided for the convenience of understanding and is not necessary for the implementation of this solution.

[0038] In step 101, a base station of a first network standard receives a first notification message sent by a network controller of a second network standard. The first network standard mainly carries data services, such as a 5G network; the second network standard mainly carries voice services, such as a 2G network or a 3G network. Since voice services have an obvious traffic tidal effect, that is, the traffic load varies in different time periods, or even there is no traffic at all in certain time periods, and the traffic load of the second network standard corresponds to the spectrum resources it occupies, that is, the higher the traffic load, the more spectrum resources the second network standard occupies. Therefore, in this step, the 2G or 3G network controller notifies the 5G base station of the first notification message indicating the current spectrum occupancy of the second network standard.

[0039] In one example, a base station is an interface device for a mobile terminal to access a first network standard, a network controller is an interface device for a mobile terminal to access a second network standard, and a base station of the first network standard receives a first notification message sent by a network controller of the second network standard through a collaborative server; wherein the collaborative server has a communication interface for communicating with the base station of the first network standard, such as Figure 2 That is to say, the 2G or 3G network controller sends the first notification information indicating the current spectrum occupancy of 2G or 3G to the collaborative server, and then the collaborative server sends the first notification information to the 5G base station, and the 5G base station receives the first notification information.

[0040] In step 102, the base station of the first network standard obtains the currently unoccupied spectrum resources in the standard spectrum resources of the second network standard as the currently available spectrum resources according to the first notification information, wherein the standard spectrum resources refer to a part of the spectrum allocated to the second network standard when it is initially deployed. If it is allocated statically, even if the second network standard does not fully occupy this part of the spectrum resources to undertake its own business, other network standards cannot occupy the currently unoccupied spectrum resources in this part of the spectrum.

[0041] In step 103, the base station of the first network standard performs spectrum resource scheduling according to the currently available spectrum resources. Since the service scheduling granularity of the base station of the first network standard can be 1ms, that is, it can schedule its own services once every 1ms, which is equivalent to being able to grasp the spectrum resource allocation in real time. The base station of the first network standard schedules its own services in real time according to the currently available spectrum resources to occupy the currently unoccupied spectrum resources in the standard spectrum resources of the second network standard.

[0042] Since the spectrum resources included in the current network standard used to carry voice services are fixed, and the voice service has an obvious traffic load tidal effect, that is, the traffic load varies in different time periods. When the traffic load is low, a part of the spectrum resources of the network standard carrying the voice service will not be occupied, resulting in too low spectrum utilization. Therefore, in an embodiment of the present invention, after receiving the first notification information sent by the network controller of the second network standard to indicate the current spectrum occupancy of the second network standard, the base station of the first network standard schedules the currently unoccupied spectrum resources of the second network standard according to the first notification information. Since the load of the voice service varies in different time periods, the first network standard can use the currently unoccupied spectrum resources of the second network standard when the load of the voice service is low to improve the spectrum utilization.

[0043] A second embodiment of the present invention relates to a spectrum sharing method, such as Figure 3 As shown, the second embodiment is substantially the same as the first embodiment, except that, in this embodiment, the network controller of the second network standard also needs to notify the base station of the third network standard, such as the 4G base station, of the first notification information, that is, the spectrum resources are shared by the three network standards. Since the third network standard exists in the cell covered by the base station of the first network standard, the base station of the first network standard and the third network standard use frequency division multiplexing or time division multiplexing to schedule the currently available spectrum resources.

[0044] In this embodiment, step 201 and step 202 are substantially the same as step 101 and step 102, and are not described in detail here. The difference is that step 203 includes the following sub-steps:

[0045] Sub-step 2031, determine whether there is a third network standard in the cell covered by the base station of the first network standard. If there is the third network standard, proceed to sub-step 2032; if not, proceed to sub-step 2034.

[0046] Sub-step 2032: Schedule spectrum resources for currently available spectrum resources using frequency division multiplexing or time division multiplexing with the base station of the third network standard.

[0047] Sub-step 2033, performing anti-interference processing on the scheduled resources.

[0048] Sub-step 2034, performing spectrum resource scheduling according to currently available spectrum resources.

[0049] Specifically, the third network standard in the present application can be a 4G network, and the third network standard is mainly used to carry data services. Similarly, the base station of the third network standard can obtain the first notification message from the collaborative server and schedule the currently available spectrum resources.

[0050] In this embodiment, the base station of the first network standard and the base station of the third network standard can share the current occupation of the spectrum resources of the two through the transmission interface for information transmission between the base stations, wherein the transmission interface can be an X2 interface. The base station of the first network standard can determine whether there is a third network standard in the cell covered by the base station of the first network standard through the X2 interface. If there is a third network standard, it means that the first network standard and the third network standard may occupy the part of the spectrum resources covered in the cell at the same time. Then the base station of the first network standard and the base station of the third network standard use frequency division multiplexing or time division multiplexing to schedule the spectrum resources of the currently available spectrum resources. If the frequency division multiplexing method is used, the first network standard and the third network standard can each independently occupy a part of the spectrum resources at the same time; if the time division multiplexing method is used, the first network standard and the third network standard can occupy the same part of the spectrum resources at different times. Both methods can effectively reduce the interference between the first network standard and the third network standard. In addition, when the network requirements are relatively high, baseband filtering and / or radio frequency filtering can also be used to perform anti-interference processing on the scheduled resources.

[0051] In one example, the base station of the first network standard and the base station of the third network standard can also share their current service loads through the transmission interface. When the service load of the first network standard is higher, the base station of the first network standard will give priority to scheduling the currently available spectrum resources. Otherwise, the base station of the third network standard will give priority to scheduling the currently available spectrum resources.

[0052] In the second embodiment of the present invention, if the base station of the first network standard determines that there is a third network standard in the cell it covers, the currently available spectrum resources are scheduled between the third network standard by frequency division multiplexing or time division multiplexing, thereby reducing the interference between the first network standard and the third network standard, and further, the scheduled resources can be subjected to anti-interference processing to improve the user experience.

[0053] A third embodiment of the present invention relates to a spectrum sharing method, such as Figure 4The third embodiment is substantially the same as the second embodiment, except that a buffer zone is provided between a first cell where the first network standard and the third network standard are deployed and an adjacent second cell where only the third network standard is deployed, and the buffer zone is used to reduce interference of the third network standard to the first network standard.

[0054] Among them, step 301 to step 303 are substantially the same as step 201 to step 203, and will not be repeated here. The difference is that there is also step 304:

[0055] Step 304: Send second notification information to a base station of the third network standard deployed in the buffer zone.

[0056] Specifically, since the cell reference signal emitted by the base station of the third network standard exists in the full spectrum, the cell deployed with the third network standard at the same time will cause interference to the adjacent cells deployed with other network standards. When there is a third network standard adjacent to the first cell deployed with the first network standard, since the cell reference signal of the third network standard exists in the full spectrum, it is bound to interfere with the first network standard. In order to minimize the interference of the cell reference signal of the third network standard to the first network standard as much as possible, a buffer zone can be set between the first cell and the second cell. Only the base station of the third network standard is deployed in the buffer zone. The base station of the first network standard sends a second notification information indicating the current spectrum occupancy of the first network standard deployed in the first cell to the base station of the third network standard deployed in the buffer zone through the X2 interface, so that the base station of the third network standard deployed in the buffer zone obtains the spectrum resources currently occupied by the first network standard according to the second notification information, and uses the occupied spectrum resources as the currently unavailable spectrum resources, and prohibits calling the currently unavailable spectrum resources. In addition, the power of the cell reference signal of the third network standard in the buffer zone can also be reduced. Since the coverage area of ​​the buffer zone is small, currently unavailable spectrum resources are disabled only within this coverage area, thereby improving the user experience of more users by sacrificing as little user experience as possible.

[0057] In a third embodiment of the present invention, a buffer zone in which only base stations of the third network standard are deployed is set between a first cell in which both the first network standard and the third network standard exist and a second cell in which only the third network standard exists. The base station of the first network standard sends a second notification message indicating the current spectrum occupancy of the first network standard deployed in the first cell to the base station of the third network standard deployed in the buffer zone, so that the third network standard obtains currently unavailable spectrum resources according to the second notification message and prohibits calling this part of the spectrum resources. That is, in this way, the impact of the cell reference signal of the full spectrum of the third network standard on the first cell is minimized as much as possible, thereby effectively improving the user experience.

[0058] A fourth embodiment of the present invention relates to a spectrum sharing method, such as Figure 5 As shown, the network controller of the second network standard that mainly carries voice services reports the current spectrum occupancy of the second network standard to the base station of the first network standard that mainly carries data services, so that the first network standard can schedule spectrum resources for the currently available spectrum resources according to the current spectrum occupancy of the second network standard.

[0059] Step 401, determining currently occupied spectrum resources.

[0060] Step 402: Generate first notification information according to currently occupied spectrum resources.

[0061] Step 403: Send first notification information to a base station of the first network standard.

[0062] Specifically, the network controller of the second network standard determines the currently occupied spectrum resources based on its own current traffic load, generates a first notification message based on the currently occupied spectrum resources, and sends the first notification message to the base station of the first network standard, so that the base station of the first network standard can obtain the currently available spectrum resources based on the first notification message, and perform spectrum resource scheduling based on the currently available spectrum resources.

[0063] In one example, after generating the first notification information, the network controller of the second network standard will send the first notification information to the base station of the first network standard, and will also send the first notification information to the base station of the third network standard, so that the base station of the third network standard can obtain the currently available spectrum resources according to the first notification information and perform spectrum resource scheduling according to the currently available spectrum resources.

[0064] In one example, multiple traffic load ranges are pre-set in the network controller of the second network standard, each traffic range corresponds to a spectrum resource size, the network controller of the second network standard obtains the current traffic load, determines the traffic load range to which the current traffic load belongs, and determines the spectrum resource size corresponding to the traffic load range, and uses this spectrum resource size as the currently occupied spectrum resource. Taking a total of 20M spectrum resources as an example, in accordance with the protocol, the first network standard and the third network standard are deployed with equal bandwidth center frequency points. Since the 2G network and 3G network occupy spectrum resources in different ways, and the 2G network belongs to a narrowband wireless communication network, it occupies less spectrum resources. Therefore, if the second network standard is a 2G network, the 2G network is deployed on both sides of the 20M spectrum. Please refer to Figure 6, since there are some spectrum resources on both sides of the 20M spectrum resources that are only used to ensure the security of the 20M spectrum resources, deploying the 2G network on both sides of the 20M spectrum can make use of the protection bands of the 4G or 5G network on both sides, so that the 2G network occupies less effective spectrum resources and can also minimize the interference of the 2G network to the first network standard and the third network standard. If the second network standard is a 3G network, deploy the spectrum resources of the 3G network on one side of the 20M spectrum resources. Please refer to Figure 7 Taking the second network standard as 3G network as an example, its standard spectrum resource is 5M, and the traffic load thresholds are pre-set in the network controller of the second network standard, which are arranged from large to small as X1, X2, X3, X4, X5 and X6, then the six traffic load thresholds can be divided into seven traffic load ranges, and the seven traffic load ranges correspond to the occupied spectrum resources of 5M, 4.6M, 4.2M, 3.8M, 3.4M, 3M and 2.6M respectively. If the network controller of the second network standard determines that the current traffic load is greater than X1, the spectrum resource currently occupied by the 3G network is adjusted to 5M. If the network controller of the second network standard determines that the current traffic load is less than X1 and greater than X2, the spectrum resource currently occupied by the 3G network is adjusted from 5M to 4.6M. If the network controller of the second network standard determines that the current traffic load is less than X2 and greater than X 3, the spectrum resources currently occupied by the 3G network are adjusted from 4.6M to 4.2M. If the network controller of the second network standard determines that the current traffic load is less than X3 and greater than X4, the spectrum resources currently occupied by the 3G network are adjusted from 4.2M to 3.8M. If the network controller of the second network standard determines that the current traffic load is less than X4 and greater than X5, the spectrum resources currently occupied by the 3G network are adjusted from 3.8M to 3.4M. If the network controller of the second network standard determines that the current traffic load is less than X5 and greater than X6, the spectrum resources currently occupied by the 3G network are adjusted from 3.4M to 3M. If the network controller of the second network standard determines that the current traffic load is less than X6, the spectrum resources currently occupied by the 3G network are adjusted from 3M to 2.6M. The same applies to when the current traffic load changes from low to high, which will not be repeated here. In addition, since the 3G network uses the same frequency networking when covering the cell, that is, the cells covered by the 3G network with different sizes of occupied spectrum resources will also cause interference, so the cells with similar distances and similar traffic loads can be divided into the same group. When the business load of most cells in the group is greater than or less than a certain threshold, all cells in the group will simultaneously expand or reduce the size of the occupied spectrum resources to minimize interference between cells.

[0065] In an example, if the second network standard is a 2G network, since the 2G network is used more to carry voice services and almost no data services, when there is no voice service on the service carrier, the service carrier of the 2G network can be directly shut down, and only the broadcast carrier can be retained. The first notification information is sent to the first network standard and the third network standard through the collaborative server, that is, all resource spectrum used for business loads is freed up for the first network standard and the third network standard to occupy, and only a part of the resource spectrum is retained for receiving user voice requests.

[0066] In the fourth embodiment of the present invention, the network controller of the second network standard determines the currently occupied spectrum resources based on its own business load, and generates first notification information based on the currently occupied spectrum resources and sends it to the base station of the first network standard, so that the base station of the first network standard can perform spectrum resource scheduling for the currently available spectrum resources according to the first notification information to improve the utilization rate of the spectrum resources.

[0067] A fifth embodiment of the present invention relates to a spectrum sharing device of a first network standard, such as Figure 8 As shown, it includes a receiving module 1, an acquisition module 2 and a scheduling module 3.

[0068] The receiving module 1, the acquisition module 2 and the scheduling module 3 all belong to a base station of a first network standard mainly used to carry data services. The receiving module 1 is used to receive a first notification message sent by a network controller of a second network standard to indicate the current spectrum occupancy status of the second network standard mainly used to carry voice services; the acquisition module 2 is used to obtain the currently available spectrum resources according to the first notification message; and the scheduling module 3 is used to perform spectrum resource scheduling according to the currently available spectrum resources obtained by the acquisition module 2.

[0069] In one example, the receiving module 1 is further used to receive the first notification information sent by the network controller through the collaborative server, wherein the collaborative server has a communication interface for communicating with a base station of the first network standard.

[0070] In an example, if a cell covered by a base station of the first network standard exists in a third network standard, the scheduling module 3 is used to schedule spectrum resources for currently available spectrum resources by using frequency division multiplexing or time division multiplexing with the base station of the third network standard.

[0071] Since the first embodiment corresponds to this embodiment, this embodiment can be implemented in conjunction with the first embodiment. The relevant technical details mentioned in the first embodiment are still valid in this embodiment, and the technical effects that can be achieved in the first embodiment can also be achieved in this embodiment. In order to reduce repetition, they are not repeated here. Accordingly, the relevant technical details mentioned in this embodiment can also be applied in the first embodiment.

[0072] A sixth embodiment of the present invention relates to a spectrum sharing device of a second network standard, such as Fig. 9 As shown, it includes a determination module 4, a generation module 5 and a sending module 6.

[0073] The determination module 4, the generation module 5 and the sending module 6 all belong to a network controller of a second network standard mainly used to carry data services. The determination module 4 is used to determine the spectrum resources currently occupied by the second network standard. The generation module 5 is used to generate a first notification information indicating the current spectrum occupancy status of the second network standard according to the currently occupied spectrum resources determined by the determination module 4. The sending module 6 then sends the first notification information to the base station of the first network standard mainly used to carry data services, so that the base station of the first network standard can obtain the currently available spectrum resources according to the first notification information and perform spectrum resource scheduling according to the currently available spectrum resources.

[0074] In one example, the determination module 4 is used to determine the traffic load range to which the current traffic load belongs according to a plurality of pre-set traffic load ranges. The determination module 4 is also used to use the size of the spectrum resource corresponding to the traffic load range to which the current traffic load belongs as the currently occupied spectrum resource; wherein the corresponding relationship between each traffic load range and the size of the spectrum resource is pre-set.

[0075] In one example, the sending module 6 is used to send the first notification information to the base station of the third network standard after the generating module 5 generates the first notification information according to the currently occupied spectrum resources, so that the base station of the third network standard can obtain the currently available spectrum resources according to the first notification information and perform spectrum resource scheduling according to the currently available spectrum resources.

[0076] Since the fourth embodiment corresponds to this embodiment, this embodiment can be implemented in conjunction with the fourth embodiment.
