Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For operators with multiple mobile cellular technologies, the mobile cellular technologies include, but are not limited to: GSM (Global System for Mobile Communications), UMTS (Universal Mobile telecommunications System), LTE (long term Evolution), CDMA2000(Code Division Multiple Access-2000), WiMAX (world Interoperability for Microwave Access), and the total spectrum resource thereof can be divided into two parts, as shown in fig. 1:
the first part is a basic part (basic frequency band) which is allocated to the mobile cellular network complete set (which may be any combination of the above mentioned mobile cellular networks such as GSM, UMTS, LTE, CDMA2000, WiMAX) in a static and unchanging manner. The cellular network corresponding to the partial frequency band can realize the basic coverage and the service continuity of the mobile cellular network. It can be understood that, since the base part network requires to be able to operate normally and independently, the system common control channel of the mobile cellular network corresponding to the base frequency band is indispensable. In addition, for any of the mobile cellular networks, the system capacity is limited due to bandwidth limitations.
The second part is a dynamic shared spectrum resource pool (dynamic frequency band), which is dynamically allocated to one or several mobile cellular networks in the above mobile cellular network complete set, and the mobile cellular networks supported by the second part can be combined and changed. It is understood that the mobile cellular network corresponding to the dynamic frequency band may complete resource allocation through the system common control channel of the base portion network, and therefore the system common control channel of the mobile cellular network corresponding to the dynamic frequency band is optional. In addition, the cellular network corresponding to the part of frequency bands can dynamically allocate the frequency spectrum resources to different mobile cellular networks based on the service requirement condition of the network, so that the change of the network requirement is met through dynamic frequency spectrum resource sharing.
The basic frequency band and the dynamic frequency band can be flexibly divided, and the unit of the basic frequency band and the dynamic frequency band can be radio frequency bandwidth occupied by a mobile cellular network or subcarrier defined in the mobile cellular network. In particular, the amount of the solvent to be used,
when the frequency band unit is a radio frequency bandwidth occupied by one mobile cellular network, for example, an operator owns two mobile cellular networks, namely GSM and UTMS, and the total spectrum resource owned by the operator is 100MHz, the operator may fixedly allocate 70MHz therein to GSM and UTMS as a basic partial spectrum; and the other 30MHz is used as a dynamic shared resource pool and is dynamically allocated to the GSM and the UTMS according to a certain proportion or a certain time period according to the demand condition of the GSM and the UTMS to the network.
When the frequency band unit is a subcarrier defined inside a mobile cellular network, for example, an operator owns two mobile cellular networks, namely GSM and LTE, and the total spectrum resource owned by the operator is 30MHz, the operator may fixedly allocate 10MHz of the frequency band unit to GSM as a basic partial spectrum; the LTE occupies 20MHz bandwidth, wherein 10MHz sub-carriers are fixedly allocated to the LTE as basic part frequency spectrum, and the other 10MHz sub-carriers can be preferentially allocated to the GSM; LTE is only allocated when GSM is not in use.
In the above description of the solution and in the following embodiments, the mobile cellular network is only a logical concept, referring to a wireless network supporting a certain mobile cellular technology; in a practical implementation, the wireless network of one entity may simultaneously support at least one mobile cellular technology. The mobile cellular network corresponding to the first part of frequency band (basic part of frequency spectrum) and the mobile cellular network corresponding to the second part of frequency band (dynamic shared resource pool frequency spectrum) may be a set of entity, or two sets of independent entities, or a combination of the two entities: partially independent, partially identical entities.
The mobile cellular technologies mentioned in the embodiments of the present invention, such as GSM, UMTS, and LTE, can be normally implemented only after acquiring the license plate frequency band, and thus are all network technologies based on the license plate frequency band.
Based on the above description of the principle of the dynamic spectrum sharing technical solution, the following describes in detail a method, a device, and a system for sharing spectrum resources according to an embodiment of the present invention with reference to the accompanying drawings.
The first embodiment is as follows:
as shown in fig. 2, the system for sharing spectrum resources according to the embodiment of the present invention includes a network management device 21, a base station 22, and a radio resource management device 23;
first, the network management device 21 divides the spectrum resource into a basic frequency band and a dynamic frequency band, where the basic frequency band is used to ensure network coverage and service continuity of multiple networks sharing the spectrum resource, and the multiple networks include at least two different mobile cellular networks, such as GSM and LTE; then, the network management device 21 is configured to fixedly allocate a basic frequency band in the spectrum resources to different mobile cellular networks in a static manner, and send spectrum resource allocation information of the basic frequency band to the radio resource management device 23 and the base station 22; furthermore, the network management device 21 is further configured to dynamically allocate a dynamic band in the spectrum resources to different mobile cellular networks, and send spectrum resource allocation information of the dynamic band to the radio resource management device 23 and the base station 22;
a radio resource management device 23, configured to manage, according to the received spectrum resource allocation information, services (such as a voice service, a real-time data service, and a non-real-time data service) related to the base station 22, and manage signal transmission power in the mobile cellular network corresponding to the basic frequency band and the dynamic frequency band;
and the base station 22 is configured to configure the spectrum resource of the base station according to the received spectrum resource allocation information of the basic frequency band and the received spectrum resource allocation information of the dynamic frequency band.
In the embodiment of the present invention, the radio resource management device may be a radio network controller or a module of a radio network controller, or may be a base station or a module of a base station.
The system for sharing spectrum resources provided by the embodiment of the invention divides the spectrum resources into a basic frequency band and a dynamic frequency band, allocates the basic frequency band and the dynamic frequency band to different mobile cellular networks in different modes, ensures the network coverage and the service continuity of each mobile cellular network by using the basic frequency band, and meets different network service requirements by using the allocation of the dynamic frequency band between different mobile cellular networks, thereby realizing the spectrum resource sharing between different mobile cellular networks.
Example two:
as shown in fig. 3, the system for sharing spectrum resources according to the embodiment of the present invention includes a network management device 31, a base station 32, and a radio resource management device 33; wherein, the middle rf module group in the base station 32 further includes: a basic IRF (Intermediate Radio Frequency) module group 321 and a dynamic IRF module group 322;
firstly, dividing total frequency spectrum resources of an operator into a basic frequency band and a dynamic frequency band through network management equipment 31; wherein, the basic frequency band is used for ensuring the basic coverage of the mobile cellular network and the continuity of the service, and the distribution mode is fixed; and the dynamic frequency band may be dynamically allocated to different mobile cellular networks.
The network management device 31 is further configured to fixedly allocate the basic frequency bands in the spectrum resources to different mobile cellular networks in a static manner, and send static spectrum resource allocation information to the radio resource management device 33 and the base station 32; correspondingly, the base station 32 configures the basic middle radio frequency module group 321 according to the received spectrum resource allocation information of the basic frequency band; and,
the network management device 31 is further configured to dynamically allocate dynamic frequency bands in the spectrum resources to different mobile cellular networks according to network service requirements, and send dynamic spectrum resource allocation information to the radio resource management device 33 and the base station 32; correspondingly, the base station 32 configures the dynamic middle rf module group 322 according to the received spectrum resource allocation information of the dynamic frequency band.
A radio resource management device 33, configured to manage, according to the received spectrum resource allocation information, services (such as a voice service, a real-time data service, and a non-real-time data service) related to the base station 32, and manage signal transmission power in the mobile cellular network corresponding to the basic frequency band and the dynamic frequency band;
further, the radio resource management device 33 further includes an allocation sub-module, configured to allocate the spectrum resources of the dynamic frequency band between different networks (e.g., the first network and the second network) according to the priority of the spectrum resources of the dynamic frequency band used by the different networks. The priority may be determined by the radio resource management device 33, or may be determined by the network management device 31 and transmitted to the radio resource management device 33.
In addition, the basic frequency band and the dynamic frequency band may have different priorities when using the wireless spectrum resource, for example, the priority of the basic frequency band corresponding to the basic service, such as network coverage and service continuity, is higher than the priority of the dynamic frequency band.
Through a priority mechanism (inside a dynamic frequency band or between a static frequency band and the dynamic frequency band), the requirements of different networks can be met on the premise of ensuring the normal conversion of frequency spectrum resources among different mobile cellular networks, and the conversion efficiency is improved.
The reallocation of the dynamic frequency band in different mobile cellular networks is uniformly managed by the network management device 31 according to different network service requirements and algorithms, but the specific responsible implementation unit may be the network management device 31, or the network management device 31 authorizes the radio resource management device 33 to implement. For example, the network management device 31 dynamically allocates wireless spectrum resources for the GSM network and the LTE network, and determines that a part of spectrum resources are allocated to the GSM network in a first time period, and switches the same part of spectrum resources to the LTE network in a second time period; then, at the end of the first time period, a handover of the partial spectrum resources from the GSM network to the LTE network may be triggered by the radio resource managing device 33;
for another example, the network management device 31 determines to transfer a part of the radio spectrum resources corresponding to the GSM network to the UMTS network and the LTE network; as for the specific allocation and handover procedures, they may be directly implemented by the network management device 31, or may be implemented by the network management device 31 authorizing the radio resource management device 32. Specifically, the radio resource management device 32 may allocate a part of the radio spectrum resources provided by the GSM network in combination with the priorities of the UMTS network and the LTE network, and switch the radio spectrum resources according to the determined allocation scheme.
In the embodiment of the present invention, the spectrum resource corresponding to the basic IRF module group 321 is the basic frequency band in the total spectrum resource, and the management of the network management device 31 on the spectrum resource configuration in the basic IRF module group 321 may be the same as the configuration of the conventional medium radio frequency module, and similarly, the spectrum allocation for different mobile cellular networks in the basic IRF module group 321 may be fixed and unchanged after the completion of the spectrum allocation.
The spectrum resource corresponding to the dynamic IRF module group 322 is a dynamic frequency band in the total spectrum resource, and the management of the network management device 31 on the spectrum resource configuration in the dynamic IRF module group 322 is a dynamic medium radio frequency module configuration mode based on a software radio technology, where the spectrum allocation of different mobile cellular networks can be dynamically changed according to the network service requirement.
In the embodiment of the present invention, the dynamic allocation of the network management device 31 to the spectrum resource corresponding to the dynamic frequency band may be implemented in, but is not limited to, the following two manners:
the first method is as follows:
the network management device 31 allocates the spectrum resources corresponding to the dynamic frequency band to different mobile cellular networks according to a preset time period.
Specifically, when the preset time period is reached, the network management device 31 schedules a part of dynamic frequency bands in the spectrum resources, and switches between different mobile cellular networks according to a predetermined scheme, that is, allocates the dynamic spectrum resources to different mobile cellular networks according to the predetermined scheme. The predetermined scheme here refers to time periods allocated for different mobile cellular networks to use spectrum resources; for example, after determining a scheme that a part of mobile spectrum resources corresponding to a GSM network needs to be allocated to an LTE network for use, the mobile spectrum resources may be switched between different networks immediately, or may be switched between different networks after a certain period of time;
for another example, when the performance of two current mobile cellular networks (GSM and LTE are taken as examples) needs to be tested, it may be set that the spectrum resources of the dynamic band are both allocated to the GSM network in the first time period, and the spectrum resources of the dynamic band are both allocated to the LTE network in the second time period.
The preset time period may be several milliseconds, several days, several weeks or several months, and the time granularity for allocating the spectrum resources of the dynamic frequency band may be arbitrarily adjusted. Allocating the spectrum resources of the dynamic frequency band according to a preset time period can dynamically support the upgrading and returning of the network, specifically, the spectrum resources can be allocated to the mobile cellular technology to be upgraded in a first time period, and the spectrum resources can be allocated to the upgraded mobile cellular technology in a second time period; and the frequency spectrum resources are distributed to the mobile cellular technology to be upgraded in the third time period, so that the advantages and the defects of the upgraded mobile cellular technology relative to the mobile cellular technology to be upgraded can be better judged, and the network upgrade is not unidirectional, fixed and long-time rigid.
The second method comprises the following steps:
in the system for sharing spectrum resources provided in this embodiment, the radio resource management device 33 further includes a reporting module, configured to count the current service states of different mobile cellular networks in real time, and report the current service states of different mobile cellular networks to the network management device 31; then the process of the first step is carried out,
the network management device 31 may schedule a dynamic frequency band in the spectrum resources to switch between different mobile cellular networks according to the received current service states of different mobile cellular networks, that is, the spectrum resources of the dynamic frequency band are allocated to different mobile cellular networks according to a predetermined scheme; the predetermined scheme here may be the proportion of the spectrum resources that can be used by the different mobile cellular networks. Taking GSM and LTE as examples, for the allocation of spectrum resources of a dynamic frequency band, the GSM network and the LTE network each occupy 50MHz, and if the current service state of the GSM network and the LTE network received by the network management device 31 indicates that the traffic of the GSM network is reduced, the network management device 31 may switch the spectrum resources of 10MHz corresponding to the GSM network to the LTE network for use according to a preset scheme; after the traffic volume of the GSM network is increased, the LTE network returns the 10MHz frequency spectrum resource occupied before to the GSM network, thereby ensuring the service performance of the GSM network; therefore, the frequency spectrum resources can be fully utilized, and the data throughput rate in the communication service is improved.
In this embodiment, the basic IRF module group 321 and the dynamic IRF module group 322 are both logical concepts, and may be a module group, or even an IRF module entity.
In combination with the description of the principle of the spectrum resource sharing technical scheme in the embodiment of the present invention, the mobile cellular network corresponding to the first partial frequency band (basic partial spectrum) includes a basic IRF module group 321 and software and hardware supporting services of the basic IRF module group 321 in each layer in the mobile cellular access network; the mobile cellular network corresponding to the second partial frequency band (dynamic shared resource pool spectrum) includes a dynamic IRF module group 322 and software and hardware supporting services of the dynamic IRF module group 322 in each layer of the mobile cellular access network.
In the mobile cellular access network shown in fig. 3, the basic service corresponding to the basic IRF module group 321 and the dynamic combination of all the mobile cellular networks corresponding to the dynamic IRF module group 322 can be simultaneously supported.
The system for sharing spectrum resources provided by the embodiment of the invention divides the spectrum resources into a basic frequency band and a dynamic frequency band, allocates the basic frequency band and the dynamic frequency band to different mobile cellular networks in different modes, ensures the network coverage and the service continuity of each mobile cellular network by using the basic frequency band, and meets different network service requirements by using the allocation of the dynamic frequency band between different mobile cellular networks, thereby realizing the spectrum resource sharing between different mobile cellular networks.
Example three:
as shown in fig. 4, a method for sharing spectrum resources provided in an embodiment of the present invention includes:
401. dividing frequency spectrum resources into a basic frequency band and a dynamic frequency band;
the basic frequency band is used for ensuring network coverage and service continuity of a plurality of networks sharing spectrum resources, and the plurality of networks comprise: a first network and a second network; the first network and the second network may be a combination of any two mobile networks in the mobile networks supported by GSM, UMTS, LTE, CDMA2000, WiMAX;
of course, the plurality of networks may also be three, four or more networks, and for convenience, the embodiment of the present invention is illustrated by taking two networks as an example, but is not limited thereto.
402. Fixedly allocating a basic frequency band in the spectrum resources to the first network and the second network in a static mode, and dynamically allocating a dynamic frequency band in the spectrum resources to the first network and the second network in a dynamic mode;
403. and sending the frequency spectrum resource allocation information of the basic frequency band and the frequency spectrum resource allocation information of the dynamic frequency band to the base station for the frequency spectrum resource allocation of the middle radio frequency module of the base station.
The method for sharing the spectrum resources provided by the embodiment of the invention divides the spectrum resources into a basic frequency band and a dynamic frequency band, allocates the basic frequency band and the dynamic frequency band to different mobile cellular networks in different modes, ensures the network coverage and the service continuity of each mobile cellular network by using the basic frequency band, and meets different network service requirements by using the allocation of the dynamic frequency band between different mobile cellular networks, thereby realizing the spectrum resource sharing between different mobile cellular networks.
Example four:
as shown in fig. 5, a method for sharing spectrum resources provided in an embodiment of the present invention includes:
501. dividing frequency spectrum resources into a basic frequency band and a dynamic frequency band;
the basic frequency band is used for ensuring network coverage and service continuity of a plurality of networks sharing spectrum resources, and the plurality of networks comprise at least two mobile cellular networks; the mobile cellular network here may be any one of the mobile networks supported by GSM, UMTS, LTE, CDMA2000, WiMAX.
502. The base bands in the spectrum resources are fixedly allocated to the at least two mobile cellular networks in a static manner, and the dynamic bands in the spectrum resources are allocated to the at least two mobile cellular networks in a dynamic manner.
In this embodiment, the implementation process of statically allocating the basic frequency band in the spectrum resource to different mobile cellular networks is basically the same as that in the prior art, and is not described herein again;
the dynamic frequency band in the spectrum resource is dynamically allocated to at least two mobile cellular networks according to the network service requirement, which may be implemented in, but not limited to, the following two ways:
the first method is as follows:
allocating the dynamic frequency band in the frequency spectrum resource to different mobile cellular networks according to a preset time period; specifically, when the preset time period is reached, scheduling a part of dynamic frequency bands in the spectrum resources to switch among different mobile cellular networks according to a predetermined scheme, that is, allocating the dynamic spectrum resources to different mobile cellular networks according to the predetermined scheme; the predetermined scheme here refers to time periods allocated for different mobile cellular networks to use spectrum resources; for example, when the performance of two current mobile cellular networks (GSM and LTE are taken as examples) needs to be tested, it may be set that the spectrum resources of the dynamic band are both allocated to the GSM network in the first time period, and the spectrum resources of the dynamic band are both allocated to the LTE network in the second time period. .
Wherein the preset period of time may be milliseconds, days, weeks, or months.
The second method comprises the following steps:
before executing the step of dynamically allocating the dynamic frequency band in the spectrum resource to the at least two mobile cellular networks, it is further required to receive the service states of the current different mobile cellular networks reported by the radio resource management device; then, according to the service states of the current different mobile cellular networks, scheduling the dynamic frequency band in the frequency spectrum resource to switch among the different mobile cellular networks, namely allocating the dynamic frequency band in the frequency spectrum resource to the different mobile cellular networks according to a preset scheme; the predetermined scheme here refers to the proportion of spectrum resources that can be used by different mobile cellular networks.
503. And sending the frequency spectrum resource allocation information of the basic frequency band and the frequency spectrum resource allocation information of the dynamic frequency band to the base station for the frequency spectrum resource allocation of the middle radio frequency module of the base station.
And then, the basic middle radio frequency module group and the dynamic middle radio frequency module group in the base station carry out spectrum allocation according to the spectrum resource allocation information of the basic frequency band and the spectrum resource allocation information of the dynamic frequency band respectively.
504. And sending the frequency spectrum resource allocation information of the basic frequency band and the frequency spectrum resource allocation information of the dynamic frequency band to a wireless resource management device, wherein the wireless resource management device is used for managing the service and the power of the base station.
After receiving the spectrum resource allocation information of the basic frequency band and the spectrum resource allocation information of the dynamic frequency band, the radio resource management device manages the services (such as voice services, real-time data services, non-real-time data services and the like) of the base station respectively aiming at the basic middle radio frequency module group and the dynamic middle radio frequency module group in the base station, and manages the signal transmission power in the mobile cellular network corresponding to the basic frequency band and the dynamic frequency band;
in addition, the wireless resource management device also allocates the spectrum resources of the dynamic frequency band among different networks according to the priority of the spectrum resources of the dynamic frequency band used by the different networks. The priority may be determined by the radio resource management device, or may be determined by the network management device and then sent to the radio resource management device. Of course, the basic frequency band and the dynamic frequency band may have different priorities when using the wireless spectrum resource, for example, the priority of the basic frequency band corresponding to the basic service, such as network coverage and service continuity, is higher than the priority of the dynamic frequency band.
Through a priority mechanism (inside a dynamic frequency band or between a static frequency band and the dynamic frequency band), the requirements of different networks can be met on the premise of ensuring the normal conversion of frequency spectrum resources among different mobile cellular networks, and the conversion efficiency is improved.
The executing body of the steps can be a network management device in the wireless network system; in addition, the number of the steps in this embodiment is not used to limit the execution order, for example, steps 503 and 504 may be executed sequentially or simultaneously.
The method for sharing the spectrum resources provided by the embodiment of the invention divides the spectrum resources into a basic frequency band and a dynamic frequency band, allocates the basic frequency band and the dynamic frequency band to different mobile cellular networks in different modes, ensures the network coverage and the service continuity of each mobile cellular network by using the basic frequency band, and meets different network service requirements by using the allocation of the dynamic frequency band between different mobile cellular networks, thereby realizing the spectrum resource sharing between different mobile cellular networks.
Example five:
in order to better implement the method for sharing spectrum resources, an embodiment of the present invention further provides a network management device for sharing spectrum resources, as shown in fig. 6, which includes a partitioning module 61, an allocating module 62, and a sending module 63; wherein,
a dividing module 61, configured to divide a spectrum resource into a basic frequency band and a dynamic frequency band, where the basic frequency band is used to ensure network coverage and service continuity of multiple networks sharing the spectrum resource, and the multiple networks at least include: a first network and a second network; the first network and the second network may be a combination of any two mobile networks in the mobile networks supported by GSM, UMTS, LTE, CDMA2000, WiMAX;
an allocating module 62, configured to statically and fixedly allocate a basic band in the spectrum resource to the first network and the second network, and dynamically allocate a dynamic band in the spectrum resource to the first network and the second network;
a sending module 63, configured to send the spectrum resource allocation information of the basic frequency band and the spectrum resource allocation information of the dynamic frequency band to the base station, where the sending module is used to allocate the spectrum resources of the base station radio frequency module.
When the allocating module 62 performs an operation of dynamically allocating a dynamic band in a spectrum resource to different mobile cellular networks, there may be, but is not limited to, the following two implementation manners:
the first method is as follows:
the allocation module 62 allocates the dynamic frequency band in the spectrum resource to different mobile cellular networks according to a preset time period; when the preset time period is reached, the allocation module 62 schedules a part of dynamic frequency bands in the spectrum resources to switch between different mobile cellular networks according to a predetermined scheme, that is, the dynamic spectrum resources are allocated to different mobile cellular networks according to the predetermined scheme; the predetermined scheme here refers to time periods allocated for different mobile cellular networks to use spectrum resources; for example, when the performance of two current mobile cellular networks (GSM and LTE are taken as examples) needs to be tested, it may be set that the spectrum resources of the dynamic band are both allocated to the GSM network in the first time period, and the spectrum resources of the dynamic band are both allocated to the LTE network in the second time period.
Wherein the preset period of time may be milliseconds, days, weeks, or months.
The second method comprises the following steps:
the network management device provided in this embodiment further includes a receiving module 64, where the receiving module 64 is configured to receive the service states of the different current mobile cellular networks reported by the radio resource management device; at this time, the allocating module 62 schedules the dynamic frequency band in the spectrum resource to switch between different mobile cellular networks according to the service states of the different current mobile cellular networks, that is, allocates the dynamic frequency band in the spectrum resource to the different mobile cellular networks according to a predetermined scheme; the predetermined scheme here refers to the proportion of spectrum resources that can be used by different mobile cellular networks.
The sending module 63 is further configured to send the spectrum resource allocation information of the basic frequency band and the spectrum resource allocation information of the dynamic frequency band to the wireless resource management device; in this way, after receiving the spectrum resource allocation information of the basic frequency band and the spectrum resource allocation information of the dynamic frequency band, the wireless resource management device manages the service, the power and the like of the base station respectively aiming at the basic middle radio frequency module group and the dynamic middle radio frequency module group in the base station; and, the spectrum resources of the dynamic band may be allocated between different networks according to the priority of the spectrum resources of the dynamic band used by the different networks (such as the first network and the second network). Of course, the basic frequency band and the dynamic frequency band may have different priorities when using the wireless spectrum resource, for example, the priority of the basic frequency band corresponding to the basic service, such as network coverage and service continuity, is higher than the priority of the dynamic frequency band. Through a priority mechanism (inside a dynamic frequency band or between a static frequency band and the dynamic frequency band), the requirements of different networks can be met on the premise of ensuring the normal conversion of frequency spectrum resources among different mobile cellular networks, and the conversion efficiency is improved.
The network management device for sharing spectrum resources provided in the embodiment of the present invention may be a radio network controller or a module of a radio network controller, or may be a base station or a module of a base station.
The network management device for sharing the spectrum resources provided by the embodiment of the invention divides the spectrum resources into a basic frequency band and a dynamic frequency band, allocates the basic frequency band and the dynamic frequency band to different mobile cellular networks in different modes, ensures the network coverage and the service continuity of each mobile cellular network by using the basic frequency band, and meets different network service requirements by using the allocation of the dynamic frequency band between different mobile cellular networks, thereby realizing the spectrum resource sharing between different mobile cellular networks.
The method, the equipment and the system for sharing the spectrum resources provided by the embodiment of the invention can actually apply the dynamic spectrum resource sharing to the license plate frequency band mobile cellular network, and in the process of realizing the dynamic spectrum sharing, the complexity of the system is not obviously improved, the prior art/standard support is complete, and the subsequent technology/standard evolution is clear; the method can partially solve the problems of mobile operator spectrum shortage, low spectrum utilization efficiency, rapid increase of data service, complex terminal proportion change, smooth transition of dynamic network and the like. In addition, in a specific scene, the overall spectrum efficiency of the network can be improved by more than 300% to the maximum in the dynamic spectrum conversion time, and the actual comprehensive throughput rate of the mobile cellular network is improved by 20% -30%.
