Description

Spectrum policy adjustment method and device under control and bearer separation architecture

technical field

The invention belongs to the field of communications, and in particular relates to a method and device for transmitting spectrum information under a control and bearer separation architecture.

Background technique

The current spectrum usage policy is fixed allocation, that is, the government allocates fixed resources for specific services of specific users, such as television, radio, radar, navigation, etc., all use fixed frequency points, some of which are not used all the time, nor are they everywhere They are all in use, so there are certain time periods or certain geographical locations, and some frequency points are not fully used. Studies have shown that a large number of spectrums that have been fixedly allocated are not fully used, which causes a great waste of spectrum resources. Among the allocated spectrum with low spectrum utilization, TV business occupies VHF (English: Very high frequency, Chinese: very high frequency) and UHF (English: Ultra High Frequency, Chinese: UHF) low frequency band below 800MHz. The frequency band with the best propagation characteristics of hundreds of megabytes. Compared with 2GHz, the coverage advantage of spectrum below 800MHz is very obvious. In the TV frequency band, not all channels are used at all times and places, and they are not used at certain times and places. These spectrums are called TV white. spectrum. Using CR (English: Cognitive Radio, Chinese: Cognitive Radio) technology to realize the dynamic spectrum access of the cellular system to the TV frequency band, so as to solve the coverage problem in areas with low population density, can greatly reduce the deployment cost of the cellular network. Cognitive radio discovers these unoccupied frequency bands that appear anytime and anywhere by sensing the wireless spectrum environment or database, and dynamically accesses these frequency bands without interfering with the PU (English: Primary User, Chinese: Primary User), so as to realize The use of the formula can improve the spectrum utilization.

In the CR system, when the primary user appears, the secondary user must exit the currently used frequency band in time to avoid interference to the primary user. In order to ensure service continuity, the secondary system needs to perform spectrum switching. When the secondary system uses the TV channel, it needs to apply for a new channel from the DB (English: Database, Chinese: Database). : spectrum manager); in the LTE (English: Long Term Evolution, Chinese: long-term evolution) network architecture, eNodeB (Evolved Node B, evolved base station), MME (English: Mobility Management Entity, mobile management entity) is a 3GPP (English: 3rdGeneration Partnership Project, Chinese: Third Generation Partnership Project) protocol LTE access network key control node, which is responsible for idle mode UE (English: User Equipment, Chinese: User Equipment) or relay positioning, paging process.

OpenFlow technology was first proposed by Stanford University. OpenFlow realizes the separation of data forwarding and routing control, and defines a set of operations that the underlying data path is open to the outside world. Future researchers can freely call the underlying operations on the controller to program, so as to realize the reform and innovation of the network. The separation of data forwarding and routing control is usually called separation of control and bearer.

With the introduction of the idea of separation of control and bearer into the wireless network system, a new wireless network architecture has emerged, which includes the following important network elements, which can specifically include: controller (controller), wireless access network, Telecom operator billing system, OTT billing system and OTT server, etc.

Among them, the controller is the core of the architecture. This network element concentrates the control plane capabilities of the wireless network, including: the control of the wireless air interface scheduling priority, the control of the core network routing, and the control of the wireless network RB (radio bear, Chinese: wireless link Road bearer) resource scheduling, scheduling of wireless spectrum resources, and so on.

As the core network element of this architecture, the Controller has interfaces with other network elements. The OR (English: open radio) 1 interface is used between the controller and the wireless access network, and the OR2 interface is used between the controller and the user terminal. The OR3 interface is used between OTT operators or virtual operators; in addition, this architecture also defines the charging interface between telecom operators and OTT operators: OR4 interface. The above OR interface is an interface customized by the manufacturer.

The existing wireless network architecture that separates control and bearer does not define the messages transmitted between the controller and the base station in detail, while in the existing LTE CR system, the spectrum information defined between the spectrum manager and the base station only includes frequency points , time, etc.; and these information do not define the information format suitable for the network where control and bearer are separated, so under the wireless network architecture where control and bearer are separated, the controller cannot control the base station equipment to use the wireless spectrum correctly.
