Detailed Description
The present application will be described in further detail with reference to the drawings and the embodiments, in order to make the objects, technical solutions and advantages of the present application more apparent.
Example 1
The first embodiment of the application provides a spectrum sharing method under different modes executed at a base station side of a first mode. In this embodiment, the first standard base station and the second standard base station are co-deployed base stations, that is: and setting base stations of two systems at the same station.
As shown in fig. 1, a flowchart of a spectrum sharing method under different standards executed at a base station side of a first standard according to a first embodiment of the present application is shown.
Step S110, detecting the frequency point occupation state of the first standard base station in the current service time slot.
The frequency point occupation state comprises: and aiming at each frequency point shared by the base station of the first system and the base station of the second system, the occupancy state of the base station of the first system is adopted. Wherein the occupancy state comprises: an occupied state (ocupy) and an idle state (idle).
Specifically, when each service time slot arrives, the occupied state of each frequency point under the service time slot by the first standard base station is detected. By the method, the occupation condition and the idle condition of each frequency point of the first system base station sharing the carrier frequency with the second system base station under the current service time slot can be obtained.
In this embodiment, the first standard base station may be a GSM base station or an LTE base station; the second standard base station may be a UMTS base station (UMTS NodeB). For example: aiming at the condition that the GSM base station and the UMTS base station share carrier frequency, the occupation state of the frequency point of the GSM base station in the current service time slot can be detected. Another example is: aiming at the condition that the UMTS base station and the LTE base station share carrier frequency, the occupied state of the LTE base station at the frequency point of the current service time slot can be detected.
Step S120, the frequency point occupation state of the first standard base station in the current service time slot is sent to the second standard base station, so that the second standard base station executes filtering processing on the frequency points occupied by the first standard base station in the current service time slot according to the frequency point occupation state of the first standard base station in the current service time slot.
When the second system base station is a UMTS base station, the frequency point occupation state of the first system base station in the current service time slot is sent to an RNC (Radio Network Controller ) of the second system base station, and the frequency point occupation state of the first system base station in the current service time slot is sent to the second system base station through the RNC.
When the first standard base station is a GMS base station, the frequency point occupation state of the first standard base station in the current service time slot is sent to the RNC of the UMTS base station through an interface (such as Iur-g interface) between the GSM base station and the RNC, and the frequency point occupation state of the first standard base station in the current service time slot is sent to the UMTS base station through the RNC.
When the first standard base station is an LTE base station, the frequency point occupation state of the first standard base station in the current service time slot is sent to the RNC of the UMTS base station through an interface between the LET base station and the RNC, and the frequency point occupation state of the first standard base station in the current service time slot is sent to the UMTS base station through the RNC.
In this embodiment, under the condition that the first system base station and the second system base station are co-deployed, the filtering processing can be performed on the frequency points occupied by the first system base station at the second system base station side according to the occupation condition of the first system base station on the frequency points, so that the problem of mutual interference in the co-deployment of different systems can be effectively solved. Further, the downlink interference of the UMTS base station to the GSM base station and to the LTE base station can be solved by the embodiment, the spectrum bandwidths of the co-deployment of the UMTS base station and the GSM base station and the co-deployment of the UMTS base station and the LTE base station can be reduced to 5MHz, the problem of shortage of 900MHz and 850MHz spectrum bandwidths is effectively solved, and more users can be accommodated in 900MHz and 850 MHz.
Example two
In a second embodiment, a spectrum sharing method under different standards executed at a base station side of a second standard is provided. In this embodiment, the first standard base station and the second standard base station are co-deployed base stations.
As shown in fig. 2, a flowchart of a spectrum sharing method under different standards executed at the base station side of the first standard according to the second embodiment of the present application is shown.
Step S210, receiving the frequency point occupation state of the first standard base station in the current service time slot, which is sent by the first standard base station.
After obtaining the occupation state of the frequency point of the first standard base station in the current service time slot, the occupation state of each frequency point in the frequency points shared by the first standard base station and the second standard base station can be determined, namely: which frequency points are being occupied by the base station of the first system and which frequency points are idle.
In this embodiment, the first standard base station may be a GSM base station or an LTE base station; the second standard base station may be a UMTS base station.
When the second standard base station is a UMTS base station, the occupation state of the frequency point of the first standard base station in the current service time slot, which is sent by the first standard base station, can be received through the RNC in the second standard base station. After receiving the frequency point occupation state of the first standard base station in the current service time slot, which is sent by the first standard base station, the RNC converts the frequency point occupation state of the first standard base station in the current service time slot into private interface data and sends the private interface data to the second standard base station through a private interface.
The private interface data may be a preset signaling message. The RNC and the second standard base station can determine the signaling message used by the RNC when the RNC sends the frequency point occupation state of the first standard base station in the current service time slot in a pre-negotiation mode. Further, the RNC and the second standard base station determine to use the public measurement initialization message to bear the frequency point occupation state of the first standard base station in the current service time slot through negotiation. Then, after receiving the occupation state of the frequency point of the first standard base station in the current service time slot sent by the first standard base station, the RNC expands the field of the occupation state of the frequency point of the first standard base station in the current service time slot to form a public measurement initialization message, and sends the public measurement initialization message to the second standard base station through a private interface.
The private interface is a communication interface between the RNC and the base station of the second system. In this embodiment, the private interface may be an Iub interface between the RNC and the base station of the second system.
After receiving the private interface data sent by the RNC, the second system base station can analyze the private interface data to obtain the frequency point occupation state of the first system base station in the current service time slot.
Step S220, according to the frequency point occupation state of the first standard base station in the current service time slot, filtering processing is carried out on the frequency points occupied by the first standard base station in the current service time slot.
In the current service time slot, for the frequency point occupied by the first standard base station, namely: the frequency points in the occupied state are subjected to filtering processing; for the frequency points not occupied by the base station of the first system, namely: the frequency bin in the idle state does not perform the filtering process.
Specifically, a downlink adaptive bandpass filter may be preset; and in the current service time slot, a downlink self-adaptive band-pass filter is utilized to execute filtering processing on the frequency point occupied by the first system base station. And not executing filtering processing on the frequency points which are not occupied by the base station of the first system. After the downstream adaptive bandpass filter is started, the downstream adaptive bandpass filter may perform filtering processing for each frequency bin separately.
For example: on the 850MHZ band, one UMTS cell and one LTE cell are co-deployed. The UMTS cell performs normal filtering, at this time, the LTE cell is deleted, and when the LET cell is deleted, the LTE base station reports a message that the frequency point of the LTE base station is released to the RNC of the UMTS base station, that is, the LTE base station sends to the RNC that the frequency point occupation state of the LTE base station in the current time slot is: the common frequency points of the LTE base station and the UMTS base station are in an idle state; the RNC informs the UMTS base station of the information that the frequency points of the LTE base station are released, and after the information that the frequency points of the LTE base station are released, which is informed by the RNC, the UMTS base station stops filtering the frequency points so as to reduce the performance loss of the UMTS base station.
In this embodiment, under the condition that the first system base station and the second system base station are co-deployed, the filtering processing can be performed on the frequency points occupied by the first system base station at the second system base station side according to the occupation condition of the first system base station on the frequency points, so that the problem of mutual interference in the co-deployment of different systems can be effectively solved. Further, the downlink interference of the UMTS base station to the GSM base station and to the LTE base station can be solved by the embodiment, the spectrum bandwidths of the co-deployment of the UMTS base station and the GSM base station and the co-deployment of the UMTS base station and the LTE base station can be reduced to 5MHz, the problem of shortage of 900MHz and 850MHz spectrum bandwidths is effectively solved, and more users can be accommodated in 900MHz and 850 MHz.
In this embodiment, the second system base station introduces a downlink adaptive band-pass filter, and performs adaptive switching on or off on the downlink adaptive band-pass filter according to the occupation condition of the first system base station on the frequency point, so as to reduce the performance loss caused by the shared carrier frequency on the second system base station.

And setting a GSM base station and a UMTS base station at the same site, and realizing 850MHz co-deployment.
On the UMTS base station side, a downlink adaptive bandpass filter is set. And when the spectrum sharing flow under different systems is executed, starting the downlink self-adaptive band-pass filter.
In the T1 time slot, the GSM BSC (Base Station Controller ) reports the message occupied by the GSM cell in the T1 time slot, f0, f1, f2, f3, f4 and f 5; RNC receives the reported message of GSM BSC, and transmits the message to UMTS NodeB; after receiving the message transmitted by the RNC, the UMTS NodeB starts the filter functions corresponding to the f0, f1, f2, f3, f4 and f5 frequency points respectively in the time slot T1, and carries out filter processing on the f0, f1, f2, f3, f4 and f5 frequency points.
In the T2 time slot, the GSM BSC reports the message that f0, f2 and f5 are occupied by the GSM cell and f1, f3 and f4 frequency points are idle in the T2 time slot to the RNC; after RNC receives the message reported by GSM BSC, the message is transmitted to UMTS NodeB; after receiving the message transmitted by the RNC, the UMTS NodeB starts the filter functions corresponding to the f0, f2 and f5 frequency points respectively in the T2 time slot, and simultaneously closes the filter functions corresponding to the f1, f3 and f4 frequency points respectively so as to carry out filter processing on the f0, f2 and f5 frequency points.
The subsequent time slots may refer to the execution flow of the T1 time slot and the T2 time slot, which is not described herein.
