s101, acquiring the current service type and the current resident network of the user terminal;
specifically, the base station obtains a service type to which a service currently being executed by the user terminal belongs, and a network in which the user terminal currently resides. It can be understood that the service types include a voice service, an uplink large service and a downlink large service, where the uplink large service is an uplink service with a higher requirement on uplink resources, and the downlink large service is a downlink service with a higher requirement on downlink resources; the network where the user terminal currently resides includes a TDD network and an FDD network.
S102, if the situation that the current resident network is inconsistent with the target network corresponding to the current service type is judged and obtained, estimating uplink frequency offset of the user terminal according to uplink control channel parameters;
specifically, if the base station judges that the network where the user terminal currently resides is inconsistent with the target network corresponding to the current service type, the base station obtains a current uplink control channel parameter and estimates the uplink frequency offset of the user terminal; and if the base station judges that the network where the user terminal resides currently is consistent with the target network corresponding to the current service type, the base station still maintains the network where the user terminal resides currently. The uplink control channel parameters include uplink channel quality measurement (SRS) and Demodulation Reference Signal (DMRS), and may also include other parameters, which may be specifically adjusted according to actual conditions, and are not specifically limited herein. It should be noted that the target network corresponding to the voice service and the uplink large service is an FDD network, and the target network corresponding to the downlink large service is a TDD network.
S103, if the uplink frequency offset of the user terminal is judged to be larger than a first preset threshold value, acquiring a network performance parameter of the target network;
specifically, if the base station determines that the uplink frequency offset of the user terminal is greater than a first preset threshold, the base station obtains a network performance parameter of the target network. The network performance parameters of the target network may include network quality parameters and load, and may also include other parameters; the first preset threshold may be specifically adjusted and set according to actual conditions, and is not specifically limited herein.
And S104, if the network performance parameters of the target network are judged to accord with the preset conditions, switching the user terminal to the target network.
Specifically, if the base station determines that the network performance parameter of the target network meets a preset condition, the base station switches the user terminal from the currently-resident network to the target network.
According to the method for processing the TDD/FDD network interoperation, if the situation that the network where the user terminal resides currently is judged to be acquired to be inconsistent with the target network corresponding to the current service type is obtained, the uplink frequency offset of the user terminal is estimated according to the uplink control channel parameter, the network performance parameter of the target network is acquired when the situation that the uplink frequency offset of the user terminal is larger than a first preset threshold value is judged to be obtained, and if the situation that the network performance parameter of the target network meets preset conditions is judged to be obtained, the user terminal is switched to the target network, so that the network quality of the user terminal of the high-speed special network is improved.
On the basis of the above embodiment, further, the current service type of the user terminal is a voice service or an uplink large service, and accordingly, the target network corresponding to the current service type is an FDD network;
the uplink large service is an uplink service in which the ratio of the number of times that the BSR value reported by the user terminal is greater than the first preset threshold to the total number of reported BSR times is greater than a second preset threshold in a first preset time period.
Specifically, when the user terminal performs an uplink service, the user terminal may Report a Buffer Status Report (BSR) for multiple times, the base station may obtain the total number of times that the user terminal reports the BSR in a first preset time period, and obtain the number of times that the BSR value reported by the user terminal is greater than a first preset threshold, if it is determined that the ratio of the number of times that the BSR value is greater than the first preset threshold to the total number of times that the user terminal reports the BSR is greater than a second preset threshold, it is determined that the uplink service has a high demand for uplink resources, and the uplink service is regarded as an uplink large service. In addition, the base station may determine whether the current service of the user terminal is a voice service by QoS bearer establishment immediate QCI1 bearer identification, and may perform voice service identification in other manners, which may be specifically adjusted according to actual conditions, and is not specifically limited herein. And the target network corresponding to the voice service and the uplink big service is an FDD network.
For example, the base station uses 100ms as a monitoring period, and in the monitoring period, when the ratio of the number of times that the BSR value reported by the ue is greater than 3413 bytes to the total number of times that the BSR value reported by the ue is greater than 50%, the base station determines that the ue is a service with high uplink resource demand, that is, a large uplink service. Then, the base station judges whether the network where the user terminal currently resides is a target network (FDD network) corresponding to the uplink large service, if the network where the user terminal currently resides is a TDD network, the base station estimates uplink frequency offset of the user terminal according to uplink control channel parameters, and if the uplink frequency offset of the user terminal is greater than the first preset threshold, the base station obtains a Reference Signal Receiving Power (RSRP) value and a load of the FDD network; and if the base station judges that the RSRP value and the load average load preset condition of the FDD network are obtained, the user terminal is switched to the FDD network.
According to the method for processing the TDD/FDD network interoperation, if the situation that the network where the user terminal resides currently is judged to be acquired to be inconsistent with the target network corresponding to the current service type is obtained, the uplink frequency offset of the user terminal is estimated according to the uplink control channel parameter, the network performance parameter of the target network is acquired when the situation that the uplink frequency offset of the user terminal is larger than a first preset threshold value is judged to be obtained, and if the situation that the network performance parameter of the target network meets preset conditions is judged to be obtained, the user terminal is switched to the target network, so that the network quality of the user terminal of the high-speed special network is improved.
On the basis of the above embodiment, further, the current service type of the user terminal is a downlink large service; correspondingly, the target network corresponding to the current service type is a TDD network;
the downlink big service is a downlink service in which the proportion of the number of times that the Transport Block Size (TBS) of the downlink resource scheduled to the user terminal is greater than a third preset threshold to the total number of times that the downlink resource is scheduled is greater than a fourth preset threshold in a second preset time period.
Specifically, when the user terminal performs a downlink service, if the ratio of the number of times that the TBS of the downlink resource scheduled to the user terminal is greater than the third preset threshold to the total number of times that the downlink resource is scheduled is greater than the fourth preset threshold in the second preset time period, the base station determines that the user terminal is a downlink service that requires a high downlink resource, that is, the downlink large service. The second preset time, the third preset threshold and the fourth preset threshold may be set and adjusted according to actual conditions, and are not specifically limited herein.
For example, the base station uses 100ms as a monitoring period, in the monitoring period, the ratio of the number of times that the TBS of the downlink resource scheduled to the user terminal is greater than f to the total number of times that the downlink resource is scheduled is greater than g, and the base station determines that the user terminal is a downlink service with a high demand for the downlink resource, that is, the downlink service. The base station judges whether the network where the user terminal currently resides is a target network (TDD network) corresponding to the downlink large service, if the network where the user terminal currently resides is an FDD network, the base station estimates uplink frequency offset of the user terminal according to uplink control channel parameters, and if the uplink frequency offset of the user terminal is greater than the first preset threshold, the base station acquires an RSRP value and a load of the TDD network; and if the base station judges and acquires the preset conditions of the RSRP value and the load average load of the TDD network, switching the user terminal to the TDD network.
According to the method for processing the TDD/FDD network interoperation, if the situation that the network where the user terminal resides currently is judged to be acquired to be inconsistent with the target network corresponding to the current service type is obtained, the uplink frequency offset of the user terminal is estimated according to the uplink control channel parameter, the network performance parameter of the target network is acquired when the situation that the uplink frequency offset of the user terminal is larger than a first preset threshold value is judged to be obtained, and if the situation that the network performance parameter of the target network meets preset conditions is judged to be obtained, the user terminal is switched to the target network, so that the network quality of the user terminal of the high-speed special network is improved.
On the basis of the above embodiment, further, the method further includes:

Specifically, if the base station judges that the network where the user terminal currently resides is inconsistent with the target network corresponding to the current service type, firstly, according to the capability information reported by the user terminal, whether the user terminal supports the target network is judged, and if the user terminal does not support the target network, the base station does not perform the subsequent operation step any more, and the process is ended; if the user terminal supports the target network, the base station estimates the uplink frequency offset of the user terminal according to the uplink control channel parameter, and continues to complete the subsequent target network switching process, which is not described herein again.
According to the method for processing the TDD/FDD network interoperation, if the situation that the network where the user terminal resides currently is judged to be acquired to be inconsistent with the target network corresponding to the current service type is obtained, the uplink frequency offset of the user terminal is estimated according to the uplink control channel parameter, the network performance parameter of the target network is acquired when the situation that the uplink frequency offset of the user terminal is larger than a first preset threshold value is judged to be obtained, and if the situation that the network performance parameter of the target network meets preset conditions is judged to be obtained, the user terminal is switched to the target network, so that the network quality of the user terminal of the high-speed special network is improved.
In the foregoing embodiments, the obtaining the network performance parameter of the target network includes:
acquiring the RSRP value and the load of the target network;
wherein the obtaining of the RSRP value of the target network comprises:
and issuing a measurement instruction for the target network to the user terminal, receiving a target network measurement report returned by the user terminal, and acquiring the RSRP value of the target network according to the target network measurement report.
Specifically, if the base station determines that the uplink frequency offset of the user terminal is greater than a first preset threshold, the base station issues a target network measurement instruction based on an a4 event to the user terminal, the user terminal performs the target network measurement after receiving the measurement instruction, and when a measurement result meets a preset a4 event threshold, the user terminal returns a target network measurement report to the base station, and the base station receives the target network measurement report and obtains an RSRP value of the target network according to the target network measurement report; the base station may also obtain the load of the target network based on the X2 link. The base station may further obtain other parameters of the target network, and may specifically adjust according to an actual situation, which is not specifically limited herein.
According to the method for processing the TDD/FDD network interoperation, if the situation that the network where the user terminal resides currently is judged to be acquired to be inconsistent with the target network corresponding to the current service type is obtained, the uplink frequency offset of the user terminal is estimated according to the uplink control channel parameter, the network performance parameter of the target network is acquired when the situation that the uplink frequency offset of the user terminal is larger than a first preset threshold value is judged to be obtained, and if the situation that the network performance parameter of the target network meets preset conditions is judged to be obtained, the user terminal is switched to the target network, so that the network quality of the user terminal of the high-speed special network is improved.

and if the RSRP value of the target network is judged to be larger than a fifth preset threshold value and the load of the target network is smaller than a sixth preset threshold value, switching the user terminal to the target network.
Specifically, if the base station judges that the RSRP value of the target network is greater than a fifth preset threshold and the load of the target network is less than a sixth preset threshold, the base station switches the user terminal to the target network. The fifth preset threshold and the sixth preset threshold may be adjusted according to actual conditions, and are not specifically limited herein.
According to the method for processing the TDD/FDD network interoperation, if the situation that the network where the user terminal resides currently is judged to be acquired to be inconsistent with the target network corresponding to the current service type is obtained, the uplink frequency offset of the user terminal is estimated according to the uplink control channel parameter, the network performance parameter of the target network is acquired when the situation that the uplink frequency offset of the user terminal is larger than a first preset threshold value is judged to be obtained, and if the situation that the network performance parameter of the target network meets preset conditions is judged to be obtained, the user terminal is switched to the target network, so that the network quality of the user terminal of the high-speed special network is improved.
On the basis of the above embodiment, the method further includes:
if the RSRP value of the target network is judged to be larger than a fifth preset threshold value and the load of the target network is not smaller than a sixth preset threshold value, acquiring the uplink frequency offset and the PRB utilization rate of each user terminal of the target network within a third preset time period;
sequencing the user terminals of the target network, of which the uplink frequency offset is not greater than the first preset threshold value, from large to small according to the PRB utilization rate, and taking the user terminals with the preset number in the front of the sequencing as the non-target user terminals of the target network;
stopping resource scheduling to the non-target user terminal, and/or releasing the resources currently scheduled to the non-target user terminal;
and switching the user terminal to the target network.
Specifically, if the base station determines that the RSRP value of the target network is greater than a fifth preset threshold but the load of the target network is not less than a sixth preset threshold, the base station obtains an uplink frequency offset and a Physical Resource Block (PRB) utilization rate of each user terminal of the target network within a third preset time period, obtains the user terminals of which the uplink frequency offset is not greater than the first preset threshold in each user terminal, sorts the user terminals of which the uplink frequency offset is not greater than the first preset threshold according to the PRB utilization rates, takes a preset number of user terminals in the top rank as non-target user terminals of the target network, stops resource scheduling to the non-target user terminals, and/or releases resources currently scheduled to the non-target user terminals, that is, migrates the non-target user terminals out of the target network, and avoiding that the static non-high-speed rail users occupy the target network resources too much, and switching the user terminal to the target network.
It should be noted that, after the base station migrates the non-target user terminal out of the target network, in a fourth preset time period, if the ratio of the number of the user terminals of the target network, of which the uplink frequency offset is greater than the first preset threshold, to the total number of the user terminals of the target network is less than a seventh preset threshold, the base station determines that the high-speed train drives away from the coverage of the base station, and then resumes resource scheduling for the non-target user terminal.
According to the method for processing the TDD/FDD network interoperation, if the situation that the network where the user terminal resides currently is judged to be acquired to be inconsistent with the target network corresponding to the current service type is obtained, the uplink frequency offset of the user terminal is estimated according to the uplink control channel parameter, the network performance parameter of the target network is acquired when the situation that the uplink frequency offset of the user terminal is larger than a first preset threshold value is judged to be obtained, and if the situation that the network performance parameter of the target network meets preset conditions is judged to be obtained, the user terminal is switched to the target network, so that the network quality of the user terminal of the high-speed special network is improved.
