 The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

For operators with multiple mobile cellular technologies, mobile cellular technologies include, but are not limited to: GSM (Global System for Mobile Communications), UMTS (Universal Mobile Telecommunication System), LTE ( Long Terms Evolution, CDMA2000 (Code Division Multiple Access - 2000), WiMAX ( Worldwide Interoperability for Microwave Access), can divide its total frequency resource into two Ministry Points, as shown in Figure 1:

 The first part is the basic part (the basic frequency band), which is allocated to the mobile cellular network ensemble in a static and invariant manner. The complete set may be any combination of the above mobile cellular networks such as GSM, UMTS, LTE, CDMA2000, WiMAX. The cellular network corresponding to this part of the frequency band can realize the basic coverage and service continuity of the mobile cellular network. It can be understood that since the basic part network requires independent working, the system common control channel of the mobile cellular network corresponding to the baseband is needed. In addition, for any of these mobile cellular networks, the system capacity is limited due to bandwidth limitations.

 The second part is a dynamically shared spectrum resource pool (dynamic frequency band), which is dynamically allocated to one or several mobile cellular networks in the entire mobile cellular network, and the supported mobile cellular networks can be combined and changed. It can be understood that the mobile cellular network corresponding to the dynamic frequency band can complete the resource allocation through the system common control channel of the basic part 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 the frequency band can dynamically allocate the spectrum resources to different mobile cellular networks based on the service demand of the network, thereby satisfying the change of the network requirements through dynamic spectrum resource sharing.

 The division of the base frequency band and the dynamic frequency band can be flexible, and the unit can be either a radio frequency bandwidth occupied by a mobile cellular network or a subcarrier defined inside the mobile cellular network. specifically,

 When the frequency band unit is the radio frequency bandwidth occupied by the mobile cellular network, for example, if an operator has two mobile cellular networks, GSM and UTMS, and the total frequency resource owned by the operator is 100 MHz, the operator can 70MHz as the base part of the spectrum, fixedly allocated to GSM and UTMS; and another 30MHz as a dynamic shared resource pool, according to GSM and UTMS network demand conditions, according to a certain proportion or according to a certain period of time dynamically allocated to GSM and UTMS.

When the frequency band unit is a subcarrier defined inside the mobile cellular network, for example, an operator has two mobile cellular networks, GSM and LTE, and the total frequency resource owned by the operator is 30MHz, the operator can use 10MHz as the basic part of the spectrum, fixedly allocated to GSM; LTE occupies 20MHz bandwidth, where 10MHz sub-carrier is fixedly allocated to LTE as the basic part of the spectrum, and the other 10MHz sub-carrier can be preferentially allocated to GSM; Assigned to LTE only when GSM is not in use.

 In the foregoing technical solution description and the following embodiments, the mobile cellular network is only a logical concept, and refers to a wireless network supporting a certain mobile cellular technology; in actual implementation, an entity's wireless network can simultaneously support at least A mobile cellular technology. The mobile cellular network corresponding to the mobile cellular network corresponding to the first part of the frequency band (the basic part spectrum) and the second part of the frequency band (the dynamic shared resource pool frequency) may be a set of entities, or two independent entities, or both. Combination: Partially independent, partially identical entities.

 The mobile cellular technologies mentioned in the embodiments of the present invention, such as GSM, UMTS, and LTE, are all required to be acquired after the license band is acquired, and therefore are all network technologies based on the license band.

 Based on the foregoing principle description of the dynamic spectrum sharing technical solution, the method, device and system for sharing spectrum resources provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

The signal transmission power in the mobile cellular network is managed.

 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 base frequency band and the spectrum resource allocation information of the dynamic frequency band.

 In the embodiment of the present invention, the radio resource management device may be a module of a radio network controller or a radio network controller, or may be a module of a base station or a base station.

 The system for sharing spectrum resources provided by the embodiments of the present invention divides the spectrum resources into two parts: a corner outband and a dynamic frequency band, and allocates them to different mobile cellular networks in different manners, and uses the basic frequency bands to ensure each mobile. The network coverage and service continuity of the cellular network, and the deployment of dynamic frequency bands among different mobile cellular networks to meet different network service requirements, thereby realizing spectrum resource sharing between different mobile cellular networks.

 Embodiment 2:

 As shown in FIG. 3, the system for sharing a frequency resource according to an embodiment of the present invention includes a network management device 31, a base station 32, and a radio resource management device 33. The medium radio frequency module group in the base station 32 further includes: a basic IRF ( Intermediate Radio Frequency, Medium Radio Frequency Module Group 321 and Dynamic IRF Module Group 322.

 First, the total spectrum resource of the operator is divided into a base frequency band and a dynamic frequency band by the network management device 31. The basic frequency band is used to ensure basic coverage and service continuity of the mobile cellular network, and the allocation manner is fixed; The dynamic frequency bands can then be dynamically allocated to different mobile cellular networks.

The network management device 31 is further configured to statically allocate the base frequency band in the spectrum resource to different mobile cellular networks in a static manner, and send the static spectrum resource allocation information to the radio resource management device 33 and the base station 32. Correspondingly, the base station 32 Configuring the radio frequency module group 321 in the base according to the received spectrum resource allocation information of the base 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; The base station 32 configures the dynamic radio frequency module group 322 according to the received spectrum resource allocation information of the dynamic frequency band.

The signal transmission power in the mobile cellular network is managed.

 Further, the RRC device 33 further includes an allocation submodule, configured to allocate a frequency of the dynamic frequency band between different networks according to priorities of spectrum resources of the dynamic frequency band according to different networks (such as the first network and the second network). Language resources. The priority may be determined by the radio resource management device 33, or may be determined by the network management device 31 and sent to the radio resource management device 33.

 In addition, the base band and the dynamic band may have different priorities when using the wireless spectrum resource. For example, the base band corresponding to the basic service such as network coverage and service continuity has a higher priority than the dynamic band.

 Through the priority mechanism (within the dynamic band, or between the static band and the dynamic band), it can meet the needs of different networks and improve the conversion efficiency while ensuring the normal conversion of spectrum resources between different mobile cellular networks.

The redistribution of dynamic frequency bands in different mobile cellular networks is managed by the network management device 31 according to network service requirements and algorithms. However, the unit responsible for implementation may be the network management device 31, or the network management device 31 authorizes wireless resource management. The device 33 is implemented. For example, the network management device 31 dynamically allocates radio frequency resources for the GSM network and the LTE network, and determines that part of the spectrum resources are allocated to the GSM network in the first time period, and the same part of the spectrum resources are switched in the second time period. To the LTE network; then, at the end of the first time period, the radio resource management device 33 may trigger the cutting of the partial frequency resource from the GSM network to the LTE network. Change.

 For another example, the network management device 31 determines to convert part of the radio frequency resource corresponding to the GSM network to the UMTS network and the LTE network; and the specific allocation and handover process may be directly implemented by the network management device 31, or may be implemented by the network management device. 31 authorizes the radio resource management device 32 to implement. Specifically, the radio resource management device 32 allocates part of the radio spectrum resources provided by the GSM network according to the priorities of the UMTS network and the LTE network, and switches 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 foregoing total spectrum resource, and the network management device 31 can manage the spectrum resource configuration in the basic IRF module group 321 with the traditional medium frequency RF module. The configuration is the same. Similarly, the spectrum allocation for different mobile cellular networks in the basic IRF module group 321 can be fixed after completion.

Assigned to different mobile cellular networks. The predetermined scheme herein refers to a time period for using spectrum resources allocated for different mobile cellular networks; for example, after determining that a part of mobile spectrum resources corresponding to the GSM network needs to be allocated to the LTE network, the scheme can be performed immediately. The switching of mobile frequency transmission resources between different networks can also be certain After the time period, the mobile frequency resource is switched between different networks.

 For example, when testing the performance of two current mobile cellular networks (for example, GSM and LTE), the spectrum resources of the dynamic frequency band may be allocated to the GSM network in the first time period, but in the first The spectrum resources of the dynamic frequency band are 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 of the spectrum resources of the dynamic frequency band may be adjusted arbitrarily. The deployment of the spectrum resources of the dynamic frequency band according to the preset time period can dynamically support the upgrade and the return of the network. Specifically, the frequency resource resources can be allocated to the mobile cellular technology to be upgraded in the first time period, in the second time period. Allocating spectrum resources to the upgraded mobile cellular technology; and allocating spectrum resources to the mobile cellular technology to be upgraded in the third time period, so that the upgraded mobile cellular technology can be better judged than the upgraded mobile cellular technology The advantages of mobile cellular technology and the existing shortcomings, but also make network upgrades are no longer one-way, fixed, long-term rigid behavior.

 Method 2:

 In the system for sharing the spectrum resource provided by the embodiment, the radio resource management device 33 further includes a reporting module, configured to perform real-time statistics on service status of different mobile cellular networks, and report the service status of different mobile cellular networks. To the network management device 31;

Mobile cellular network; the predetermined scheme here may be the proportion of spectrum resources that can be used by different mobile cellular networks. Taking GSM and LTE as an example, the current allocation of the frequency band resources of the dynamic frequency band, the GSM network and the LTE network each occupy 50 MHz, for example, the service status of the current GSM network and the LTE network received by the network management device 31 indicates the service of the GSM network. If the amount is decreased, the network management device 31 may switch the 10 MHz spectrum resource corresponding to the GSM network to the LTE network according to a preset scheme. After the traffic of the GSM network recovers, the LTE network returns the previously occupied 10 MHz spectrum resource to the LTE network. GSM network, thus ensuring the service performance of the GSM network; The source is fully utilized and the throughput of data in the communication service is increased.
