Description

Spectrum sharing method and network center control entity

This application claims priority to Chinese Patent Application No. 201210480746.8, entitled "Construction Method and Apparatus for a Business Message", filed on November 23, 2012, the entire contents of which are incorporated by reference. In this application. Technical field

The present invention relates to the field of communications, and in particular, to a spectrum sharing method and a network center control entity. Background technique

With the rapid development of LTE (Long Term Evolution) technology,

The GSM (Global System for Mobi le) business will gradually shrink, and the market share of GSM will become less and less in the future, especially in the developed regions of the world economy.

In order to comply with the above development trends and to make maximum use of the GSM spectrum at the same time, the industry has proposed the concept of spectrum sharing, that is, when the GSM service demand is relatively small, a part of the GSM spectrum is vacated to the LTE network, or UMTS (Universal Mobi le Telecommunication System) , Universal Mobile Telecommunications System) Users of the network. Taking GSM network and LTE network spectrum sharing (referred to as GL spectrum sharing) as an example, common GL spectrum sharing needs to plan GO (GSM Only) area, GL spectrum sharing area and GL shared buffer area (Buffer Zone) when laying out the network. ) , where the use of the original GSM spectrum by each region is as follows:

1) For the G0 area, the GSM cell in the area can normally use all the GSM spectrum owned by the operator;

2) For the GL spectrum sharing area, all the GSM spectrum owned by the operator is divided into two consecutive parts, one part is reserved for the GSM cell in the area, and the other part is the shared spectrum, which is transferred to the area. LTE cell use;

3) For the GL shared buffer area, the GSM cell in this area can only be used The GSM spectrum portion reserved for the GSM cell in the GL spectrum sharing area and the width of the buffer area need to be spatially required to reach 3 station spacing, thereby ensuring the performance of the LTE cell in the GL spectrum sharing area.

In an existing spectrum sharing scenario, the GSM spectrum transmission process may specifically include: 1) a BSC (Base Stat i on Contro l l er , a base station controller) acquires a buffer area and a GL spectrum sharing area from a network management entity;

2) The BSC detects the total amount of GSM cell traffic in the buffer area and the GL spectrum shared area;

3) If the total amount of GSM cell traffic in the buffer area and the GL spectrum sharing area is lower than the threshold, the BSC vacates the to-be-shared spectrum by turning off part of the GSM carrier frequency of the buffer area and the GL spectrum sharing area;

4) The BSC informs the network management entity that GSM has shared the spectrum;

5) The network management entity activates the LTE cell in the GL spectrum sharing area and completes the configuration of the supporting S1 interface and the X2 interface. If the LTE basic spectrum exists in the GL spectrum sharing area, the network management entity may also notify the LTE to use the shared spectrum through the CA mode.

The GSM spectrum recovery stream may specifically include:

1) The total amount of GSM cell traffic in the BSC monitoring buffer area and the GL spectrum sharing area under the state that GSM has shared spectrum with LTE;

2) If the buffer area and the GL spectrum sharing area satisfy the spectrum recovery condition, the BSC notifies the network management entity to perform spectrum recovery;

3) The network management entity deactivates the LTE cell and activates the supporting S1 interface and the X2 interface.

The above prior art has the problem that the buffer area cannot use the shared bandwidth resource, and the utilization of the spectrum of the wireless network is reduced. The existing solution determines the satisfaction of the total amount of GSM cell traffic in the buffer area and the GL spectrum shared area. Whether to recycle the shared spectrum of the GL spectrum shared area. However, the recovery action involves all the GSM cells and LTE cells of the buffer area and the GL spectrum sharing area, which lacks flexibility, and the existing schemes cause traffic congestion in some GSM cells in the buffer domain when the GL spectrum is shared, but the buffer area and When the total amount of GSM cell traffic in the GL spectrum sharing area does not trigger the spectrum recovery condition, the network does not actively adjust these GSM cells with traffic congestion, thereby making the office The communication status of the network has not been improved and the user experience has been affected.

An embodiment of the present invention provides another method for spectrum sharing. In order to explain the method provided by the embodiment of the present invention, the GL (GSM and LTE) spectrum sharing is taken as an example. The GSM network is used as the first network. The LTE network is the second network (of course, not limited thereto, the second network may also be UMTS). As shown in FIG. 2, the method includes:

The S20 K network center control entity obtains network planning information obtained from the network management entity. Delineate the GL shared area, buffer area, and GSM dedicated area.

5202. The network center control entity acquires the total GSM traffic of the GL shared area and the buffer area. If the GSM total traffic of the GL shared area and the buffer area is greater than a preset threshold, executing S203; if the GL shared area and the buffer area are If the total GSM traffic is not greater than the preset threshold, then S204 is performed.

5203. The network center control entity determines whether spectrum sharing is enabled. If spectrum sharing is enabled, the shared spectrum is recovered, and S202 is performed at the beginning of the next adjustment period. If spectrum sharing is not enabled, S202 is directly executed.

5204. The network center control entity determines whether spectrum sharing is enabled. If spectrum sharing is not enabled, execute S205, and execute S206 after executing S205. If spectrum sharing is enabled, execute S206 directly.
