Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for spectrum sharing.

Background

The wireless spectrum is a limited resource with economic and social values, and the main spectrum allocation method at present allocates a fixed frequency band for each network, for example, the uplink frequency band of the connected 2G network is 909MHZ-915MHZ, and the uplink frequency band of the connected 3G network is 1940MHZ-1955 MHZ. By adopting the allocation method, when a certain network has a certain number of idle frequency bands, other networks cannot use the idle frequency bands and only can use the frequency bands allocated to the network, thereby causing the waste of frequency spectrum resources.

In order to improve the utilization rate of the frequency spectrum, a scheme for sharing the frequency spectrum is proposed in the prior art, and specifically, the scheme comprises the following steps: according to the frequency spectrum using conditions of different networks, under the condition of meeting a certain condition, a part of idle frequency spectrum of the network with lower frequency spectrum utilization rate is allocated to the network with tense frequency spectrum resources for use.

By adopting the technical scheme, when a certain network has the idle frequency spectrum, the idle frequency spectrum is considered to be allocated to other networks for use; when no free spectrum exists in all networks, dynamic allocation of the spectrum cannot be realized. This limits the flexibility and applicability of spectrum sharing.

the allocation module is used for allocating the appointed frequency band of the first network to the second network so that the second network can transmit services by using the appointed frequency band, and the frequency spectrum income of the first network is less than that of the second network.

Different from the prior art, when a certain network has idle frequency spectrum, the idle frequency spectrum is considered to be allocated to other networks for use, the frequency spectrum sharing method and the device provided by the invention determine the frequency spectrum allocation among the networks through the frequency spectrum income of each network, and even if the frequency spectrum utilization rate of a plurality of networks is higher, the assigned frequency band of the network with low frequency spectrum income can be given to the network with high frequency spectrum income according to the difference of the frequency spectrum income of each network, thereby improving the flexibility and the applicability of frequency spectrum sharing.

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.

As shown in fig. 1, a schematic diagram of a base station system architecture provided by the present invention includes: a plurality of base stations 11 and a base station controller 12. The base station 11 is used to establish networks of different systems, such as a GSM (Global System for Mobile communications) network, a UMTS (Universal Mobile telecommunications System) network, and an LTE (Long term Evolution System) network. The base station controller 12 is used to control the subordinate base stations 11, and mainly functions to perform wireless channel management, implement call and communication link establishment and removal, and the like.

As shown in fig. 2, an implementation of the spectrum sharing method according to the embodiment of the present invention is applied to the base station system shown in fig. 1, and the implementation subject of the spectrum sharing method is a base station controller. The method comprises the following steps:

101. and acquiring the spectrum profit of each network.

In the specific implementation process of this step, the base station controller sends a request command to each base station, and then receives response information returned by the base station, where the response information carries the spectrum revenue of the network corresponding to the base station. Or the base station controller receives the report information sent by each base station, wherein the report information carries the spectrum income of the network corresponding to the base station.

Wherein the spectrum profit of the network represents the business income of the network per unit spectrum in unit time. The spectrum gain of each network is calculated by a gain calculation formula. In particular, the followingThe revenue calculation formula may be: p ═ Σ αi×SiX Vi) ÷ W/T, where P denotes the spectral yield per unit time, αiWeight, S, representing importance of the ith serviceiIndicating the total traffic volume, V, of the ith service in the network during time TiThe unit income of the ith service is shown, W represents the spectrum bandwidth of the network, and T represents a certain time length.

It is noted that T may be a period of time in the past or a period of time in the future. When T is used to represent the historical time period, the spectral yield over the historical time period can be calculated by the formula. When T is used to represent a future time period, the spectral gain for the future time period can be estimated by the formula.

Wherein the service comprises: voice services (long distance calls, city calls, etc.), value-added services (multimedia messages, short messages, etc.), data services (internet access, online video viewing, etc.). In practical application, operators can make alpha of each service according to different scenesi、Vi. For example, the call quality of the GSM network is better than that of the LTE network, and in order to ensure better experience of the call of the client, α of the voice service of the GSM network may be setiAlpha greater than voice traffic of LTE networki

102. And allocating the appointed frequency band of the first network to a second network so that the second network transmits services by using the appointed frequency band.

The first network and the second network are used for representing the relative relation of the spectrum income of different networks, and the spectrum income of the first network is smaller than the spectrum income of the second network.

Specifically, when there are only two different networks and the two networks have different spectrum gains, the network with the larger spectrum gain is the second network, and the network with the smaller spectrum gain is the first network.

When there are multiple different networks and the spectrum profit of each network is different, there may be a case that the spectrum profit of a certain network is greater than that of multiple other networks, and the spectrum profit is largerOne network is the second network and the other networks are the first networks. For example: there are A, B, C, D four networks with a corresponding spectral yield PA、PB、PC、PDAnd P isA<PB<PC<PDThen, since the spectrum gains of the network A, B, C are all smaller than those of the network D, the network D is the second network and the network A, B, C is the first network corresponding to the network D. As for the network C, the network C is the second network, and the network A, B is the first network corresponding to the network C.

When the assigned frequency band of the first network is allocated to the second network, the allocation mode may be fixed allocation or dynamic allocation.

Specifically, the fixed allocation means that the bandwidth of the designated frequency band allocated to the second network by the first network is a fixed value.

The dynamic allocation means that the bandwidth of the designated frequency band allocated to the second network by the first network is increased or decreased according to a predetermined strategy.

The preset strategy is to distribute frequency bands according to the service condition of the first network, and correspondingly reduce the bandwidth of the specified frequency band when the first network service is busy; and when the first network service is idle, correspondingly increasing the bandwidth of the appointed frequency band.

Or, the predetermined strategy is to allocate a frequency band according to a ratio of the spectrum profit of the first network to the spectrum profit of the second network. When the ratio is smaller, the frequency spectrum gain of the first network is smaller than that of the second network, and the bandwidth of the specified frequency band is correspondingly increased; and when the ratio is larger, the frequency spectrum income of the first network is closer to the frequency spectrum income of the second network, and the bandwidth of the specified frequency band is correspondingly reduced.

In addition, in order to ensure that the first network can normally work after the assigned frequency band is given, the assigned frequency band needs to be limited. Optionally, the bandwidth of the designated frequency band is smaller than a preset bandwidth; or, the ratio of the bandwidth of the specified frequency band to the total bandwidth of the first network is smaller than a preset ratio.

In a specific implementation manner of this embodiment, after the first network gives up the specified frequency band to the second network, the first network stops transmitting the service by using the specified frequency band.

Different from the prior art, when a certain network has idle frequency spectrum, the idle frequency spectrum is considered to be allocated to other networks for use, the frequency spectrum sharing method provided by the invention determines the frequency spectrum allocation among the networks through the frequency spectrum income of each network, and even if the frequency spectrum utilization rate of a plurality of networks is higher, the assigned frequency band of the network with low frequency spectrum income can be given to the network with high frequency spectrum income according to the difference of the frequency spectrum income of each network, thereby improving the flexibility and the applicability of frequency spectrum sharing.

For example, in the base station system shown in fig. 1, it is assumed that one of the base stations is base station a, and the other base station is base station B. The working frequency band of the GSM network corresponding to the base station A is 800MHZ to 900MHZ, and the working frequency band of the LTE network corresponding to the base station B is 900MHZ to 1000 MHZ.

In combination with the application scenario, an embodiment of the present invention further provides a spectrum sharing method, as shown in fig. 3, including:

201. the base station A calculates the frequency spectrum gain P of the GSM network according to the gain calculation formulaGSM(ii) a The base station B calculates the frequency spectrum profit P of the LTE network according to the profit calculation formulaLTE

Wherein, PGSMLess than PLTE

202. The base station A gets the frequency spectrum PGSMSending the obtained spectrum gain P to a base station controller, and sending the spectrum gain P to a base station BLTEAnd sending the data to a base station controller.

203. Base station controller by comparing PGSM、PLTEDetermining that the GSM network is the first network and the LTE network is the second network.

204. The base station controller determines the frequency band allocated to the LTE network by the GSM network to be 850MHZ-900 MHZ.

205. The base station controller sends a notification message to the base station A to notify the base station A to stop transmitting the services of the GSM network by using the frequency band of 850MHZ to 900 MHZ.

206. And the base station A receives the notification information sent by the base station controller and stops transmitting the services of the GSM network by using the frequency band of 850MHZ to 900 MHZ.

207. The base station controller sends notification information to the base station B to notify the base station B that the service of the LTE network can be transmitted by using the frequency band of 850MHZ to 900 MHZ.

208. And the base station B receives the notification information sent by the base station controller and can transmit the service of the LTE network by using the frequency band of 850MHZ to 900 MHZ.

Through the steps, the designated frequency band corresponding to the GSM network with small frequency spectrum income is distributed to the LTE network with large frequency spectrum income, and the flexibility and the applicability of frequency spectrum sharing can be further improved.

In practical applications, a base station may be interfered by external environment, especially by neighboring base stations. In the process of spectrum sharing, if a network is severely interfered, and the frequency band of the network is also allocated to other networks, the normal operation of the network may be affected.

In order to solve the above problem, and in a case where one second network corresponds to only one first network, another spectrum sharing method provided in an embodiment of the present invention is provided. Referring to fig. 4, the method includes:

301. and acquiring the spectrum profit of each network.

302. When there is only one first network, an interference parameter of the first network is determined.

Wherein the interference parameter is used for representing the degree of interference to the network.

In the specific implementation process of this step, the base station controller calculates the interference parameter of the first network by obtaining the transmission power of each base station and the distance between each base station and the base station of the first network. Or the base station controller receives the interference parameters reported by the base station of the first network.

303. And when the interference parameter of the first network meets a preset requirement, allocating the designated frequency band of the first network to the second network.

The preset requirement may be that the interference parameter of the first network is smaller than a preset value.

According to the frequency spectrum sharing method provided by the embodiment of the invention, the designated frequency band of the first network with low frequency spectrum income is allocated to the second network with high frequency spectrum income, so that the flexibility and the applicability of frequency spectrum sharing are improved. Meanwhile, the assigned frequency band is allocated after the interference parameter of the first network is judged to meet the preset condition, so that the problem that the first network cannot work normally due to the fact that the assigned frequency band is allocated to the second network under the condition that the interference of the first network is serious is solved.

404. And allocating the specified frequency band of the first network with the minimum revenue interference to a second network.

For example, there are A, B, C, D four networks, where network a is the second network with higher spectral benefit, network B, C, D is the first network corresponding to network a, and the benefit interference and ranking of network B, C, D is SB>SD>SCThen, the assigned frequency band of network C is allocated to network a because the net interference of network C is minimal.
