In this embodiment, if the sub-band is an FDD sub-band, the frequency point number corresponding to the sub-band reuses the FDD frequency point number of the LTE standard, but the uplink and the downlink are used in reverse. That is, the uplink frequency point number of the sub-band uses the FDD downlink frequency point number defined in the 3GPP36.101 standard, the downlink frequency point number of the sub-band uses the FDD uplink frequency point number defined in the 3GPP36.101 standard, the range of the uplink frequency point number is selected from 0 to 17999, and the range of the downlink frequency point number is selected from 18000 to 35999; preferably, the range of the uplink frequency point number is 0 to 17999, and the range of the downlink frequency point number is 18000 to 35999.

Fig. 3 is a flowchart of a third embodiment of the LTE frequency band processing method according to the present invention, and as shown in fig. 3, on the basis of the above embodiment, the specific implementation steps of the LTE frequency band processing method include:
s301: selecting a first frequency band number, wherein the first frequency band number is any frequency band number not defined in the 3GPP36.101 standard.
S302: -defining a sub-band under said first band number.
In this embodiment, if the subband is defined as the FDD subband, steps S303 and S304 are performed; if the sub-band is defined as the TDD sub-band, steps S305 and S306 are performed.
S303: if the sub-band is an FDD sub-band, selecting continuous frequency point numbers as the range of the uplink frequency point numbers in all FDD downlink frequency point number ranges in the 3GPP36.101 standard, and selecting continuous frequency point numbers as the range of the downlink frequency point numbers in all FDD uplink frequency point number ranges in the 3GPP36.101 standard.
S304: broadcasting the first frequency band number through a System Information Block (SIB) 1; and indicating the selected uplink frequency point number and uplink bandwidth in the frequency information of the SIB2, and indicating the sub-band number in the frequency information indication of the SIB20, so that the terminal device reports whether the sub-band is supported.
In this embodiment, for a cell using a sub-Band, a baseband processing Unit (BBU) broadcasts a private network frequency Band number on frequency information (freqband indicator information element) in SIB1, adds a sub-Band indicator information element in SIB20 (or other SIBs), and parses a TDD768 cell IE in a UE capability report message sent by a UE, where the IE is redefined, and carries the sub-Band number supported by the UE and a private network capability identifier. The BBU also analyzes the different-frequency-band measurement parameters between the first frequency band number carried in the MeasParameters- > BandListEUTRA item in the message and the frequency band numbers supported by other UEs, and considers that all the sub-frequency bands supported by the terminal equipment have the same different-frequency-band measurement parameters as the first frequency band number.
The terminal equipment receives the frequency segment number in SIB1, if it is the first frequency segment number it supports, and continues to receive the frequency segment number in SIB20 (or other SIBs), if the terminal supports the frequency segment, it can try to camp on the cell, otherwise it continues to search for other cells. And in the process of accessing the terminal into the network, the terminal reports the terminal capability, and the supported sub-frequency band number is carried in the TDD768 IE.
S305: and if the sub-band is a TDD sub-band, selecting continuous frequency point numbers in all TDD uplink frequency point number ranges in the 3GPP36.101 standard as the range of the downlink frequency point numbers.
S306: and indicating the sub-frequency band number in the frequency information indication of the SIB20 so that the terminal device reports whether the sub-frequency band is supported.
In this embodiment, a sub-band indication information element is added to SIB20 (or other SIBs), and TDD768 IEs in UE capability report are analyzed, where the IE is redefined to carry the supported sub-band numbers and the private capability identifier of the private communication network. And resolving the pilot frequency band measurement parameters between the nominal frequency band number carried in the MeasParameters- > BandListEUTRA item and the frequency band numbers supported by other UEs, and considering that all the frequency bands supported by the terminal equipment have the pilot frequency band measurement parameters which are better the same as those of the first frequency band. The terminal receives the segment number in SIB1 and continues to receive the sub-segment number in SIB20 (or other SIBs) if it is the first segment number it supports, and may attempt to camp on the cell if it supports the sub-segment, otherwise continues to search for other cells. And in the process of accessing the terminal into the network, the terminal reports the terminal capability, and the supported sub-frequency band number is carried in the TDD768 IE. And (2) pilot frequency band measurement parameters between the first frequency band number carried in the MeasParameters- > BandListEUTRA item and the frequency band numbers supported by other UEs (all the supported sub-bands have the same pilot frequency band measurement parameters with the frequency band corresponding to the first frequency band number).
Specifically, for FDD subbands, the uplink frequency bin number and uplink bandwidth are indicated in freqinfo of SIB2, and TDD subbands do not carry this field.
The IRAT-Parameters UTRA-TDD768 cell in the UE capability report message is originally used to indicate the capability of the UE to support the 7.68M chip/s TDD spread spectrum system, and since this type of system is already abandoned at present, there is no network in actual use. Therefore, the cell is meaningless, and the embodiment of the present invention redefines the cell, uses the first bits in the cell to indicate the increased UE capability of the private communication network, where one bit is whether the UE supports sub-bands, and if the UE supports sub-bands, the cell carries the number of sub-bands supported by the UE and the number of sub-bands of each supported sub-band.
In the LTE frequency band processing method provided in this embodiment, an undefined frequency band number in the 3GPP36.101 standard is selected as a first frequency band number, a frequency sub-band is defined under the first frequency band number, and an uplink frequency point number corresponding to the frequency sub-band is further set to reuse a downlink frequency point number of the 3GPP36.101 standard, a continuous frequency point number is selected from the downlink frequency point number of the 3GPP36.101 standard as an uplink frequency point number range corresponding to the frequency sub-band, the uplink frequency point number corresponding to the frequency sub-band reuses an uplink frequency point number of the 3GPP36.101 standard, a continuous frequency point number is selected from the uplink frequency point number of the 3GPP36.101 standard as a downlink frequency point number range corresponding to the frequency sub-band, and the first frequency band number is broadcast through SIB1 in the process of being applied to a private communication network; the frequency information of the SIB2 indicates the range of the selected uplink frequency point number and the selected downlink frequency point number, and the frequency information of the SIB20 indicates the sub-band number, so that the terminal device reports whether the sub-band is supported.
