Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.
In the embodiments of the present invention, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated object, indicating that there may be three relationships, for example, a and/or B, which may indicate: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. In the description of the present invention, the character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
For example, the narrowband system according to the embodiment of the present invention may be a police Digital Trunking system (PDT), an Integrated Digital Enhanced Network (iDEN), a GT-800 Digital Trunking Network, a Tetra (Terrestrial Trunked Radio) narrowband system, or a Digital Mobile Radio standard (DMR). The embodiments of the present invention are not limited thereto. In addition, the broadband system and the broadband service according to the embodiment of the present invention are all exemplified by the fifth Generation mobile communication technology (5th Generation, 5G), and may be other broadband systems and broadband services, and thus, the embodiment of the present invention is not limited to the 5G broadband.
As an example, one possible application scenario applicable to the embodiment of the present invention is as follows: in the existing narrowband spectrum resources, such as Public Protection and Disaster Relief (PPDR), almost all of which are divided into narrowband systems, since the utilization rate of the spectrum resources of a 5G broadband system is much higher than that of a narrowband system, in order to improve the utilization rate of the spectrum resources, broadband data services and narrowband data services need to be gradually and preferentially carried on the 5G broadband system, and meanwhile, under the condition that the 5G broadband system is related to the narrowband system in terms of language coverage, part of narrowband voice trunking services can be gradually migrated to the 5G broadband system to be carried. Compared with the narrow-band system which processes the same service, the 5G broadband system improves the frequency resource utilization rate, and the 5G broadband system also supports the following multimedia services: telephone voice, cluster voice, multimedia message, video, Geographic Information System (GIS), data service, and command scheduling. In this scenario, in order to improve the spectrum utilization rate of a narrowband spectrum resource, an embodiment of the present invention provides a method for allocating a bandwidth resource, where an existing narrowband spectrum resource is used, and according to a usage frequency and a busy/idle time period of a narrowband service, the existing narrowband spectrum resource is planned to be a narrowband sub-band spectrum resource and a 5G broadband sub-band spectrum resource, so as to carry a current narrowband service through the narrowband sub-band spectrum resource and a 5G broadband service through the 5G broadband sub-band spectrum resource, thereby implementing that a broadband service is also supported under the condition of supporting the narrowband service, and thus improving the utilization rate of the spectrum resource.
The following describes the technical solution of the present invention and how to solve the above technical problems with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a schematic flowchart of a method for allocating bandwidth resources according to an embodiment of the present invention, where the method for allocating bandwidth resources may be implemented by a bandwidth resource allocation device, and the bandwidth resource allocation device may be independently configured or may be configured in a spectrum resource management device, for example, please refer to fig. 1, and the method for allocating bandwidth resources may include:
s101, obtaining the use frequency and the use time period of the current narrow-band service to the narrow-band spectrum resource.
The narrowband spectrum resource is used for bearing narrowband services, so that the narrowband system can process the narrowband services by using the narrowband spectrum resource. The frequency of using the narrow-band frequency spectrum resources by the narrow-band service is related to the narrow-band service volume, and when the narrow-band service volume is small, the occupied narrow-band frequency spectrum resources are less; when the amount of the narrowband service is large, it indicates that the frequency of using the narrowband frequency spectrum resource by the narrowband service is high, and the occupied narrowband frequency spectrum resource is large.
For example, in the embodiment of the present invention, the usage frequency of the narrowband spectrum resource is related to the usage time period, consumption of different users, and other factors. For example, in some busy time periods, such as 8:00-18:00 on a workday, 20: 00-1: 00 in the morning on christmas, holidays on major festivals, national day festivals or spring festival, etc., the busy time periods are busy time periods for processing narrow-band data traffic, and the frequency of using narrow-band spectrum resources in the time periods is high. And in the night time period of a large office building, the idle time period is used for processing the narrow-band data service, and the use frequency of narrow-band spectrum resources in the time period is low.
After acquiring the usage frequency and the usage time period of the current narrowband service to the narrowband spectrum resource, the following S102 may be performed:
and S102, dividing the narrow-band spectrum resources into a plurality of sub-band spectrum resources according to the use frequency and the use time period.
The multiple sub-band spectrum resources comprise narrow-band sub-band spectrum resources and 5G wide-band sub-band spectrum resources; the narrowband sub-band spectrum resource is used for bearing the current narrowband service, and the 5G broadband sub-band spectrum resource is used for bearing the 5G broadband service. Optionally, the multiple sub-band spectrum resources may further include a wide-narrow shared sub-band spectrum resource, where the wide-narrow shared sub-band spectrum resource is used to carry a narrowband service or a 5G broadband service. Illustratively, the number of the wide-narrow shared sub-band spectrum resources is at least one.
It should be noted that, in the embodiment of the present invention, the existing narrowband spectrum resources are divided into multiple subband spectrum resources to release narrowband spectrum resources that are not occupied by the narrowband service, and the released narrowband spectrum resources may be used to carry other 5G broadband services. Therefore, in the plurality of divided sub-band spectrum resources, a part of bandwidth is spectrum resource for carrying current narrow-band service, the spectrum resource is used as narrow-band sub-band spectrum resource, another part of bandwidth is spectrum resource for carrying 5G broadband service, and the spectrum resource is used as 5G broadband sub-band spectrum resource. In addition, since the traffic volume of the 5G broadband service and the narrowband service varies at any time, the fixed spectrum resource division cannot completely adapt to the demand of the spectrum resource when the 5G broadband service and the narrowband service vary at any time, therefore, when the existing narrowband spectrum resource is divided into a plurality of subband spectrum resources, a part of the wide-narrow shared subband spectrum resource can be further divided, and the wide-narrow shared subband spectrum resource can be used for carrying the narrowband service or the 5G broadband service.
Taking an example of a TETRA narrowband system, the TETRA system allocates and uses spectrum resources in a Time division manner, the TETRA system is a Time Division Multiple Access (TDMA) frame format, the frame format includes a plurality of Time slots, one Time slot is a specific Time interval and is equivalent to one channel, users transmit and receive data services through the channel, the Time slots have different lengths, a plurality of users are allowed to process the data services by using the same frequency in one Time slot, and each user uses their own Time slot to transmit and receive service data. The time domain of the 5G broadband system is scheduled and allocated to the frequency domain and the time domain of the 5G wideband subband spectrum resource according to the frame format and the time slot format of 10ms, 5ms, 1ms, 0.5ms, 0.25ms, 0.125ms, 0.0625ms, and 0.03125 ms. The slot format of the 5G broadband system has greater flexibility, where a maximum slot is 10ms, a minimum slot is 0.03125ms, and if a time interval is not used by the narrowband system in the wide-narrow shared subband spectrum resource, for example, if the time interval is 13ms, the time interval may be used by the 5G broadband system, the 5G broadband system may divide the time interval into a plurality of different time slots according to the requirement of the 5G broadband service, and is used by the 5G broadband system to process the 5G broadband service, if the time interval is 0.04ms, the time interval may be used as one time slot 0.03125ms by the 5G broadband system, and if the time interval is detected to be 0.02ms, because the minimum slot of the 5G broadband system is 0.03125ms, it may be determined that the time slot may not be used by the 5G broadband system. In addition, the 5G broadband system can reasonably arrange 5G broadband services according to the size of the time interval, so that the optimal spectrum efficiency can be obtained, if the time interval is large, the 5G broadband system can use the frequency band in a certain period of time, and if the time interval is small, the 5G broadband system can determine whether to use the frequency band according to the service requirements of the 5G broadband system. The time division multiplexing of the narrow-band system and the 5G broadband system is realized, and the utilization rate of narrow-band frequency spectrum resources is improved.
Similarly, taking the narrow-band system as the TETRA system as an example, the TETRA operating frequency is 806MHz-821MHz and 851-866MHz, the whole TETRA narrow-band spectrum resource can be used as the carrier bandwidth of the 5G broadband system to perform spectrum resource division to divide three sub-band resources, where the three sub-band resources are respectively a narrow-band sub-band spectrum resource, a wide-narrow shared sub-band spectrum resource, and a 5G wide-band sub-band spectrum resource. As shown in fig. 2, fig. 2 is a schematic diagram of a spectrum division method according to an embodiment of the present invention. As can be seen from fig. 2, a plurality of wide and narrow shared sub-band spectrum resources may be established according to the capacity of the narrow band service and the service mode in the busy/idle time period. Wherein, TETRA Bandwidth (BWP) represents a narrow-band sub-band spectrum resource, 5G BWP represents a wide-band sub-band spectrum resource, and DYN1, DYN2, DYN3 represent three wide-narrow shared sub-band spectrum resources. The narrowband spectrum resources may be partitioned only if the spectrum bandwidth is greater than 5M. For example, the spectrum bandwidth may be a PPDR spectrum, an iDEN spectrum, or a P25 spectrum.
For example, when dividing the narrowband spectrum resource in the TETRA system, the carrier bandwidth of the 5G broadband system may be set to 15MHz, where TETRA BWP of the TETRA system is 2MHz, 5G BWP of the 5G broadband system is 10MHz, and the wide and narrow shared sub-band spectrum resource DYN BWP shared by the 5G broadband system and the TETRA system is 3 MHz. When the 3MHz wide and narrow shared sub-band spectrum resources are DYN1, DYN2, and DYN3, the bandwidths of the three wide and narrow shared sub-band spectrum resources may be set according to TETRA service conditions, for example, DYN1 ═ DYN2 ═ DYN3 ═ 1MHz, DYN1 ═ 0.8MHz, DYN2 ═ 1.5MHz, and DYN3 ═ 0.7MHz may be set.
It can be understood that in a Frequency Division Duplex (FDD) system, two independent channels are used for transmitting information downwards and upwards respectively, that is, two independent channels are required for FDD operation, and one channel is used for transmitting information from a base station to a user equipment; another channel is used to transmit information from the user equipment to the base station. In this case, the uplink spectrum resource and the downlink spectrum resource of the bearer service of the FDD system may be divided, and the uplink spectrum resource may be divided into a narrowband sub-band spectrum resource, a 5G wideband sub-band spectrum resource, and a wide-narrow shared sub-band spectrum resource. The downlink spectrum resources can also be divided into narrow-band sub-band spectrum resources, 5G wide-band sub-band spectrum resources and wide-narrow shared sub-band spectrum resources, the division of the uplink spectrum resources is irrelevant to the division of the downlink spectrum resources, the division of the uplink spectrum resources is divided according to the use condition of the uplink narrow-band service on the narrow-band spectrum resources, and the division of the downlink spectrum resources is divided according to the use condition of the downlink narrow-band service on the narrow-band spectrum resources.
The method for allocating bandwidth resources provided by the embodiment of the invention utilizes the existing narrow-band spectrum resources to firstly acquire the use frequency and the use time period of the narrow-band spectrum resources by the current narrow-band service; dividing the narrow-band frequency spectrum resources into a plurality of sub-band frequency spectrum resources according to the use frequency and the use time period; the plurality of sub-band spectrum resources comprise narrow-band sub-band spectrum resources and 5G wide-band sub-band spectrum resources; the narrowband sub-band spectrum resource is used for bearing the current narrowband service, and the 5G broadband sub-band spectrum resource is used for bearing the 5G broadband service. On the premise of ensuring the support of the narrow-band service, the 5G broadband service can be processed by the wide-narrow shared sub-band spectrum resources divided from the narrow-band spectrum resources, so that the narrow-band system and the 5G broadband system can share the narrow-band spectrum resources, and the spectrum utilization rate of the narrow-band spectrum resources is improved.
Based on the embodiment shown in fig. 1, after dividing the narrowband spectrum resource into a plurality of subband spectrum resources according to the usage frequency and the usage time period, the condition of the plurality of subband spectrum resources is not constant, but may change with the usage frequency and the usage time period of the current narrowband service to the narrowband spectrum resource, and correspondingly, the narrowband spectrum resource may be divided again based on the change, for example, as shown in fig. 3, fig. 3 is a flowchart of another bandwidth resource allocation method provided in the embodiment of the present invention, and the bandwidth resource allocation method may further include:
s301, when the frequency and time period of using the narrow-band spectrum resources by the current narrow-band service change, the narrow-band spectrum resources are divided again.
Because the traffic of the 5G broadband service and the narrowband service is changed at any time, the utilization rate of the spectrum resources of the 5G broadband system is higher than that of the narrowband system, the narrowband service gradually migrates to the 5G broadband service, and the narrowband data service is preferentially borne on the 5G broadband system. When the narrowband spectrum resources are subsequently utilized to process the narrowband service or the 5G broadband service, the narrowband spectrum resources can be divided again according to the use condition of the current narrowband service on the narrowband sub-band spectrum resources and the equipment condition for processing the narrowband service, so that the replanting of the narrowband system and the 5G broadband system on the narrowband spectrum resources is realized, the flexibility of spectrum resource allocation is increased, and the utilization rate of the narrowband spectrum resources is further improved.
For example, when the frequency and the time period of use of the narrow-band spectrum resources by the current narrow-band service change, and the narrow-band spectrum resources are re-divided, if the current narrow-band service decreases, the narrow-band sub-band spectrum resources divided from the narrow-band spectrum resources can already meet the requirements of the current narrow-band service, and the narrow-band service does not need to be processed by occupying the wide-narrow shared sub-band spectrum resources, at this time, the wide-narrow shared sub-band spectrum resources can be all allocated to the 5G broadband system, and in this case, the wide-narrow shared sub-band spectrum resources can all be used for carrying the 5G broadband service.
Therefore, in the embodiment of the invention, when the frequency and the time period of using the narrow-band spectrum resources by the current narrow-band service change, the narrow-band spectrum resources are divided again, so that the narrow-band system and the 5G broadband system can be used for replanting the narrow-band spectrum resources, and the spectrum utilization rate of the narrow-band spectrum resources is further improved.
Based on the embodiment shown in fig. 1 or fig. 3, after dividing the narrow-band spectrum resources into multiple sub-band spectrum resources, in order to enable the 5G network device to carry the 5G broadband service through the wide-narrow shared sub-band spectrum resources when the wide-narrow shared sub-band spectrum resources are unoccupied, the narrow-band network device may further send the frequency point information of the wide-narrow shared sub-band spectrum resources and the unoccupied idle time period to the 5G network device, for example, please refer to fig. 4, which is a schematic flowchart of a flowchart of still another allocation method of bandwidth resources provided by the embodiment of the present invention, where the allocation method of bandwidth resources may be implemented by an allocation device of bandwidth resources, the allocation device of bandwidth resources may be independently configured, and may also be configured in the narrow-band network device, and the allocation method of bandwidth resources may include:
s401, acquiring the occupation situation of the wide and narrow shared sub-band spectrum resources.
The bandwidth-shared sub-band spectrum resource is obtained by dividing a narrow-band spectrum resource into a plurality of sub-band spectrum resources by spectrum resource management equipment according to the use frequency and the use time period of the narrow-band spectrum resource by the current narrow-band service, wherein the plurality of sub-band spectrum resources comprise a narrow-band sub-band spectrum resource and a 5G wide-band sub-band spectrum resource; the narrowband sub-band spectrum resource is used for bearing the current narrowband service, and the 5G broadband sub-band spectrum resource is used for bearing the 5G broadband service.
S402, according to the occupation situation of the wide and narrow shared sub-band spectrum resources, sending the frequency point information of the wide and narrow shared sub-band spectrum resources and unoccupied idle time periods to the 5G network equipment, so that the 5G network equipment can bear 5G broadband services through the wide and narrow shared sub-band spectrum resources in the unoccupied idle time periods according to the frequency point information.
For example, for a wide and narrow shared sub-band spectrum resource, the time period of the wide and narrow shared sub-band spectrum resource may be set to a semi-static time period and a dynamic time period. In a semi-static time period, transmitting and receiving 5G broadband service data at the same frequency spectrum resource position every other fixed time period; in a dynamic time period, when the narrow-band system does not occupy the spectrum resources of the wide-narrow shared sub-band, before the 5G broadband system sends 5G broadband service data each time, unoccupied time period indication information is sent to the user equipment, and the user equipment receives the 5G broadband service data on the spectrum resources indicated by the unoccupied time periods.
And according to the occupation condition of the narrow-band service on the narrow-band shared sub-band spectrum resource, informing the frequency point information of the narrow-band shared sub-band spectrum resource and the time period of the narrow-band system not occupying the narrow-band shared sub-band spectrum resource to the adjacent 5G network equipment of the narrow-band system base station, so that the adjacent 5G network equipment analyzes and dynamically schedules the narrow-band shared sub-band spectrum resource according to the occupation condition of the narrow-band service on the narrow-band shared sub-band spectrum resource. For example, if the spectrum resources of the narrow and wide shared sub-bands are not used by the narrow band system at certain time intervals corresponding to the TDMA frame format, a time division multiplexing manner may be adopted, so that the 5G broadband system schedules the 5G users to receive and transmit 5G broadband service data using the spectrum resources, thereby implementing that the 5G broadband system processes the 5G broadband service using the frequency resources of the narrow and wide shared sub-bands in an idle time period of the narrow band system, implementing the time division multiplexing between the narrow band system and the 5G broadband system, and improving the utilization rate of the narrow band spectrum resources.
When the frequency point information of the wide and narrow shared sub-band spectrum resources and unoccupied idle time periods are sent to the 5G network equipment according to the occupation condition of the wide and narrow shared sub-band spectrum resources, optionally, a target wide and narrow shared sub-band spectrum resource with the idle time periods can be determined in the wide and narrow shared sub-band spectrum resources according to the occupation condition of the wide and narrow shared sub-band spectrum resources; and then sending the frequency point information of the target wide and narrow shared sub-band spectrum resource and the unoccupied idle time period to the 5G network equipment.
It can be seen that, by determining the target wide and narrow shared sub-band spectrum resource with the unoccupied idle time period, and then sending the unoccupied idle time period and the frequency point information corresponding to the unoccupied idle time period to the 5G network device, the 5G network device can directly use the target wide and narrow shared sub-band spectrum resource to process the 5G broadband service, and does not need to analyze and dynamically schedule according to the use state of the wide and narrow shared sub-band spectrum resource, so that the load of the 5G network device is reduced, and the data transmission efficiency is improved.
When the 5G broadband system is applied to a high frequency band application, since the propagation characteristics of radio waves are not good, beam scanning and beam management are required to be introduced for communication, and a Synchronization module (SSB) that transmits a default beam is also required when transmitting and receiving service data. An SSB is set in the center of the 5G carrier bandwidth, and is used to transmit control signaling and service data, and the SSB has a fixed time domain position and a frequency domain occupying 20 channels (Radio bearer, RB) and is used for Radio link bearer. As shown in fig. 5, fig. 5 is a schematic diagram of another spectrum division method according to an embodiment of the present invention, and on the basis of fig. 2, fig. 5 shows a setting position of SSB during spectrum division.
As can be seen from fig. 5, in the embodiment of the present invention, the carrier bandwidth of the 5G broadband system may be set to 15MHz, the TETRA BWP of the TETRA system is 2MHz, the 5G BWP of the 5G broadband system is 10MHz, and the wide and narrow shared sub-band spectrum resource DYN BWP shared by the 5G broadband system and the TETRA system is 3 MHz. The SSB is set at the center position of the carrier bandwidth of the default 5G broadband system at 7.5MHz, and in practical applications, the SSB is set at the center position of 5G BWP at 5MHz in the divided 5G broadband sub-band spectrum resources, so that it is necessary to configure a frequency Offset to the SSB, where the Offset is the difference between the center position of the carrier bandwidth of the 5G broadband system and the center position of the 5G BWP, that is, 2.5 MHz. A Physical Broadcast Channel (PBCH) message carried in each SSB, a Transmission Time Interval (TTI) of the PBCH message is agreed, after frequency offset is performed in the PBCH frequency domain, a Demodulation Reference Signal (DMRS) associated therewith is also frequency offset, and the DMRS is used for Channel correlation Demodulation in a 5G wideband system.
For example, for a Physical Random Access Channel (PRACH), the time domain configuration of the PRACH is not affected by the division of narrowband spectrum resources, and may remain unchanged, and the frequency domain configures the frequency offset of the PRACH according to the bandwidth frequency position of the 5G wideband spectrum resources. When a narrowband spectrum resource is divided, the configuration of the common parameter of the PDCCH is configured according to an initial common bandwidth of Channel coding, and the DMRS of the PDCCH performs frequency offset according to the initial common bandwidth of the Channel coding. In a Physical Uplink Control Channel (PUCCH), when a narrowband spectrum resource is divided, a common parameter of the PUCCH is configured according to an initial common bandwidth of Channel coding, and a DMRS of the PUCCH is frequency-shifted according to the initial common bandwidth of Channel coding.
For example, when the wide and narrow shared sub-band spectrum resources are divided into DYN1, DYN2, and DYN3, the bandwidths of the three wide and narrow shared sub-band spectrum resources may be set according to TETRA service conditions, for example, DYN1 ═ 0.8MHz, DYN2 ═ 1.5MHz, and DYN3 ═ 0.7MHz may be set. In a possible implementation manner, bandwidths of three wide and narrow shared sub-band spectrum resources, namely DYN1, DYN2 and DYN3, are occupied by a TETRA system and are all used for processing narrow-band services; the bandwidth that the UE can use for sending and receiving the service data with the 5G broadband system is a default initial bandwidth BWP0, which is 10MHz consistent with the 5G BWP. In a possible implementation manner, with the reduction of the narrow-band traffic, it is not necessary to occupy multiple wide-narrow shared sub-band spectrum resources to process the narrow-band traffic, for example, the wide-narrow shared sub-band spectrum resources of DYN1 are not occupied, and may be allocated to the 5G broadband system for use all the time. The UE and the 5G broadband system may transmit and receive service data at BWP1, where BWP1 ═ BWP0+ DYN1 ═ 10.8 MHz. In another possible implementation manner, as the narrowband service is reduced, the narrowband service does not need to occupy multiple narrow and wide shared subband spectrum resources to process the narrowband service, for example, the shared subband spectrum resources of DYN1 and DYN2 are not occupied, and may be allocated to the 5G broadband system all the time, the UE and the 5G broadband system may transmit and receive service data using BWP2, and BWP 2-BWP 0+ DYN1+ DYN 2-12.3 MHz. In another possible implementation manner, with the reduction of the narrowband service, the narrowband sub-band spectrum resources divided from the narrowband spectrum resources may be used to process the narrowband service, and it is not necessary to occupy the wide-narrow shared sub-band spectrum resources to process the narrowband service, at this time, the wide-narrow shared sub-band spectrum resources may be all allocated to the 5G broadband system for use, and the UE and the 5G broadband system may transmit and receive service data using BWP3, where BWP3 is BWP0+ DYN1+ DYN2+ DYN3 is 13MHz, in this case, the wide-narrow shared sub-band spectrum resources may all be used to carry the 5G broadband service.
Optionally, when the frequency point information and the unoccupied idle periods of the wide and narrow shared sub-band spectrum resources are sent to the 5G network device according to the occupation situation of the wide and narrow shared sub-band spectrum resources, the frequency point information and the unoccupied idle periods of the wide and narrow shared sub-band spectrum resources may be sent to the 5G network device through the communication interface.
For example, when the frequency point information of the wide and narrow shared sub-band spectrum resources and the unoccupied idle time periods are sent to the 5G network device through the communication interface, timing reference signals may be configured in both the narrow band network device and the 5G network device, so as to keep the timing synchronization of the air interfaces between the narrow band network device and the 5G network device; and then a communication interface is added between the narrow-band network equipment and the 5G network equipment, and the frequency point information of the wide-narrow shared sub-band frequency spectrum resources and unoccupied idle time periods can be sent to the 5G network equipment through the communication interface, so that the 5G network equipment can perform time division multiplexing of the 5G broadband system on the wide-narrow shared sub-band frequency resources unoccupied by the narrow-band system according to the use conditions of the wide-narrow shared sub-band frequency spectrum resources, the TDMA frames and the time domain time slots between the narrow-band network equipment, and the utilization rate of the frequency spectrum resources is further improved.
It can be understood that the communication interface may be used for information interaction between the narrowband network device and the 5G network device, and the narrowband network device may be a narrowband base station, a narrowband switching center, or a network element such as a narrowband system network manager, and the narrowband network device in the communication interface is not limited in the present invention, as long as the narrowband network device can transmit parameters of the narrowband system to the 5G network device. The following parameters may be passed on the communication interface: the method comprises the following steps of narrow-band sub-band spectrum resource information, wide-narrow shared sub-band spectrum resource information, frequency point information of wide-narrow shared sub-bands, unoccupied time periods of wide-narrow shared sub-band spectrum resources, time scheduling information of wide-narrow shared sub-band frequency points, interference information of wide-narrow shared sub-bands and narrow-band service information.
Therefore, in the embodiment of the invention, after the occupation condition of the wide and narrow shared sub-band spectrum resources is obtained, the frequency point information of the wide and narrow shared sub-band spectrum resources and the unoccupied idle time periods can be sent to the 5G network device according to the occupation condition of the wide and narrow shared sub-band spectrum resources, so that the 5G network device can bear 5G broadband services through the wide and narrow shared sub-band spectrum resources in the unoccupied idle time periods of the wide and narrow shared sub-band spectrum resources, the narrow band system and the 5G broadband system can share the narrow band spectrum resources, and the spectrum utilization rate of the narrow band spectrum resources is improved.
