Embodiment 1

FIG. 15 is a flowchart 1 of a method for replacing a frequency band according to Embodiment 1 of the present invention. As shown in FIG. 15, the process includes the following steps:

Step S1502: The terminal detects that the wireless signal strength sent by the second base station in the first frequency band is higher than a threshold, where the terminal accesses the first base station and performs wireless communication with the first base station in the first frequency band.

Step S1504: The terminal reports, to the first base station, identifier information of the second base station acquired from the signal sent by the second base station;

Step S1506: The first base station determines an address of the second base station according to the identifier information of the second base station.

Step S1508: The first base station sends a frequency band replacement request to the second base station.

In practice, multiple base stations may exist in the same area and are operated by different operators, so unified control and management cannot be achieved. Although the terminal performs wireless communication with the first base station on the first frequency band, it is likely that the second base station operates in the first frequency band not far from the first base station, such that the wireless signals transmitted by the first base station and the second base station There is interference between each other, which causes the communication of the terminal to be affected.

In the embodiment of the present invention, the terminal is configured to detect the radio signal in the first frequency band that is sent by the second base station, and if the interference is greater than the threshold, report the identifier information of the second base station to the first base station, where The identification information is obtained by the terminal from the signal sent by the second base station (the sequence of obtaining the information and the terminal detecting the wireless signal sent by the second base station in the first frequency band is not limited), for example, the terminal reads the second base station to send The broadcast signal acquires the message (for example, a Master Information Block (MIB) or a System Information Block (SIB) information in a Long-Term Evolution (LTE) system) .

After receiving the identification information of the second base station, the first base station determines the address of the second base station, and sends a frequency band replacement request thereto, so that the second base station changes the frequency band to avoid interference between the two base stations.

For example, the terminal reports that the identity information of the second base station is the cell global ID cellGlobalId of the second base station, including a Public Land Mobile Network-Identity (PLMN-Identity) and a cell identity CellIdentity, where the PLMN-Identity The carrier bearer information, such as China Mobile's PLMN is 46000, 46002 or 46007, China Unicom's PLMN is 46001 or 46006, and so on; CellIdentity carries the number of the base station. With this information, the second base station can be uniquely identified.

After receiving the identification information of the second base station, the first base station determines the address of the second base station according to the information, and facilitates sending a frequency band replacement request to the second base station, so that the second base station replaces the frequency band, so as to prevent the terminal from being subjected to the first frequency band. Interference.

The method for reporting the information of the second base station to the first base station by the terminal in the embodiment of the present invention, and the manner in which the first base station sends the frequency band replacement request to the second base station can effectively solve the interference problem between the base stations, and can also avoid the hidden node. The problem is that even if the first base station and the second base station cannot detect each other and thus cannot detect each other's interference (mutually hidden nodes, usually due to walls or other obstructions), The terminal detects interference and reports the first base station to resolve the interference problem.

The foregoing embodiments of the present invention may be applied to a licensed or unlicensed frequency band. For example, the second base station originally works in the first Licensed frequency band, and after receiving the frequency band replacement information, changes to the second Licensed frequency band; or originally works in the first Unlicensed frequency band. After the band replacement information is changed to the second Unlicensed band; or originally working in the first Licensed band, after receiving the band replacement information, then changing to the second Unlicensed band, and so on.

In the embodiment of the present invention, the connection between the first base station and the second base station is not limited, and may be performed by a wired or wireless manner, such as a copper wire, an optical fiber connection, or the like, and the wireless mode uses, for example, a wifi protocol, an LTE protocol, or Wireless connections made by other wireless communication protocols/specifications, etc.

The terminal form in the embodiment of the present invention is not limited, and may be a mobile phone (or mobile phone), or other device capable of transmitting or receiving a wireless signal, including a personal digital assistant (PDA), a wireless modem. Wireless communication device, handheld device, laptop computer, cordless phone, Wireless Local Loop (WLL) station, Customer Premise Equipment (CPE) capable of converting mobile signals into wifi signals ) or wireless fidelity (WIreless-FIdelity, referred to as Mifi), smart home appliances, or other devices that can spontaneously communicate with the mobile communication network without human operation.

The base station is not limited in form, and may be a Macro Base Station, a Pico Base Station, a Node Node B, an Evolved Node B (ENB), or a Home Enhanced Base Station (Femto eNB or Home). eNode B (HENB)), a relay station, an access point, a remote radio unit (RRU), and a radio radio head (RRH).

The air interface between the base station and the terminal is not limited, and may be Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access 2000 (CDMA2000), and global microwave interconnection. Worldwide Interoperability for Microwave Access (WiMAX), LTE, LTE-Advanced, etc.

The above address in the embodiment of the present invention is not limited, and is preferably an IP address.

The frequency band replacement request sent by the first base station to the second base station includes first frequency band start time information of the first base station; and the second base station determines whether to replace the frequency band according to the information.

The first base station and the second base station may be deployed by different operators or different homes respectively, and their right to use the frequency band should be fair; in order to solve the interference problem, the present invention proposes a "first come, first served" manner, ie, which base station When the first frequency band is occupied first, the user who causes the interference should avoid it, and the uniform rule is adopted to achieve the self-discipline effect. Therefore, in the present invention, the frequency band replacement request sent by the first base station to the second base station includes the first frequency band start time information of the first base station, and the second base station compares the time information with the time when the user starts to use, if Earlier, the frequency band is not replaced, otherwise the frequency band is replaced to avoid interference with the terminal.

FIG. 16 is a second flowchart of a frequency band replacement method according to Embodiment 1 of the present invention. As shown in FIG. 16, the flowchart includes steps including the following steps in addition to all the steps shown in FIG. 15:

Step S1602: The second base station compares the initial use time of the first frequency band of the first base station with the initial use time of the first frequency band of the first base station, and if the first base station is earlier, replaces the working frequency band of the first frequency band;

Step S1604, if the second base station is earlier, feed back a negative response to the first base station and continue to work on the first frequency band.

That is, if the second base station uses the first frequency band earlier than the first base station, the frequency band does not need to be replaced, and a negative response is fed back to the first base station; if the first base station receives a negative response, the first base station should be replaced. The operating band avoids interference with terminals accessing the second base station.

The first base station stores the mapping relationship between the base station address and the base station identification information in advance, and after receiving the identification information of the second base station, determines the address of the second base station according to the mapping relationship; or the first base station sends the identifier information of the second base station to the other A network device (same as the predetermined network device described above) and receiving an address of a second base station that is responsive from other network devices.

In the LTE protocol in the related art, the cellGlobalId reported by the terminal includes only the PLMN-Identity and the CellIdentity, and the first base station does not know the physical address (such as the IP address) of the second base station, so that the second base station cannot be directly addressed according to the information. . Regarding the method for the first base station to address the second base station, the first base station may pre-store a mapping relationship (eg, a mapping table) between the cellGlobalId (or the PLMN-Identity and the CellIdentity) of the second base station and the address of the second base station; After receiving the cellGlobalId information of the second base station reported by the terminal, the first base station can address the second base station according to the information, and send a frequency band replacement request to the second base station, where the mapping relationship is preferably stored in the first In the base station, or sent by other devices to the first base station in advance (for example, the first base station receives mapping relationship information of neighboring cells sent by other devices when deployed, and the like).

Or, the first base station sends the cellGlobalId of the second base station to the other network device, and the latter, according to the information, and the mapping relationship between the cellGlobalId and the base station address stored in the second base station, acquires the address information of the second base station, and sends the address information to the first base station. . Compared with the previous method, the method is more unified, and the first base station needs to store a large amount of mapping relationship information, and the first base station belonging to a certain operator cannot obtain information of base stations of other operators.

The other network devices are not limited in form, and may be any device connected to the first base station and the second base station, preferably a cloud storage server, capable of transmitting an indication to the first and second base stations.

Step S1702: The terminal detects that the wireless signal strength sent by the second base station on the first frequency band is higher than a threshold, where the terminal accesses the first base station and performs wireless communication with the first base station on the first frequency band.

Step S1704: The terminal reports, to the first base station, identifier information of the second base station acquired from the signal sent by the second base station;

Step S1706: The first base station sends the identifier information of the second base station to the other network device, so that the other network device sends the frequency band replacement request to the second base station according to the information.

Step S1708, the other network device determines the base station that needs to perform the band switching, and sends a band replacement request to the determined base station.

Different from the first embodiment, in the embodiment of the present invention, the first base station may not directly send the frequency band replacement request to the second base station, but send the identification information of the second base station to other network devices, and the second network device to the second network device. The base station sends the request.

Similar to the first embodiment, other network devices need to store the mapping relationship between the identity information of the base station and the address of the base station, so as to conveniently obtain the address of the second base station and send a frequency band replacement request thereto.

In fact, other network devices are a "fair" role of a third party, and preferably do not belong to one of the operators. Therefore, after receiving the identification information of the second base station sent by the first base station, other network devices may determine that they should A band change request is sent to the first base station.

The other network device selectively transmits a band change request to the base station according to the base station starting to use the first frequency band starting time of the first frequency band.

Similar to the first embodiment, it is still determined here whether or not to replace the frequency band based on time. The other network device acquires the first frequency band start usage time of the first and second base stations, that is, the first frequency band start usage time, and determines, according to the information, whether to send the frequency band replacement request to the first or the second base station, if The first base station uses the first frequency band earlier, and then transmits a frequency band replacement request to the second base station, and vice versa.

The acquisition of the time information of the first frequency band by the base station may be reported by the base station to the other network equipment periodically, or the base station may report the other network equipment after the frequency band is replaced, or report the other information when the interference situation of the present invention occurs. Network equipment and so on. The manner of reporting may also be that each base station reports the same, or the first base station acquires the first frequency band start time information of the second base station and sends the information to other network devices.

Embodiment 3

FIG. 18 is a flowchart of a method for replacing a frequency band according to Embodiment 3 of the present invention. As shown in FIG. 18, the process includes the following steps:

Step S1802, the terminal detects that the wireless signal strength transmitted by the second base station on the first frequency band is higher than a threshold, where the terminal accesses the first base station and performs wireless communication with the first base station on the first frequency band;

Step S1806: The first base station sends an indication to the terminal according to the identifier information of the second base station, and triggers the terminal to use a specific frequency band replacement request resource to send a signal, where the signal may include a physical uplink control channel PUCCH signal or a sounding reference signal SRS. The second base station receives the signal and avoids using the first frequency band;

Step S1808: The terminal sends a signal to the second base station on the frequency band replacement request resource.

Step S1810: After receiving the signal sent by the terminal, the second base station performs a frequency band replacement process.

Unlike the foregoing embodiment, in this embodiment, the entity that transmits the band change request to the second base station becomes the terminal instead of the first base station or other network device. Since there may be several base stations in the vicinity of the first base station, in order to facilitate the transmission of the frequency band replacement request to the second base station instead of other base stations, the present invention proposes that different base stations correspond to different frequency band replacement request resources. The terminal receives the signal sent by the second base station and obtains the identifier of the second base station, and sends the identifier to the first base station, where the first base station instructs the terminal to send a signal on the frequency band replacement request resource corresponding to the second base station according to the message, and the second base station only needs to The signal is detected on the resource, and the frequency band is replaced after receipt.

In order to achieve fairness, the terminal may further send other information to the second base station, or the second base station acquires the information by other network devices, for example, the first frequency band start time information of the first base station, etc., so that the second base station can receive the second base station. After the band replacement request, it is judged whether or not the frequency band needs to be replaced, and the present invention is not limited.

The signal sent by the terminal may be a PUCCH or SRS signal in the LTE system. The resources of the signal are time, frequency or orthogonal code resources. For example, in an LTE system, each transmission time interval (TTI) is 1 ms in length, and the system bandwidth is divided into several physical resource blocks (PRBs), which can be on the same PRB. In the embodiment of the present invention, the first base station may send signaling to the terminal, and trigger the terminal to send the PUCCH or the SRS on the resource corresponding to the second base station, in the embodiment of the present invention. For example, the a-th orthogonal code resource on the PRB numbered 1 is detected in a period of 10 ms, and the second base station only needs to detect signals on the resources, and when it is detected, it is considered that the frequency band needs to be replaced.
