When a user wants to perform a VoLTE voice service or a data service, for example, the user wants to initiate a VoLTE call, browse a web page, or download a file such as a video, the user may send a service request through a user equipment UE such as a mobile phone, and then the service request sent by the user equipment UE is received in step S101.
And step S102, determining the service type corresponding to the service request according to the service request.
Wherein, the service request includes the relevant information for describing the requested service. If the service request is a request for requesting a VoLTE voice service, the service request includes VoLTE call information, and the VoLTE call information specifically includes information such as a calling and called number and a VoLTE registration state of the subscriber identity card; if the service request is a request for requesting data service, the service request includes information such as a data packet request address, a data packet identifier to be requested, and a data packet size to be requested.
Specifically, if the service request includes VoLTE call information, which indicates that the service request is a request for requesting a VoLTE voice service, determining that the service type corresponding to the service request is the VoLTE voice service; and if the service request comprises the size of the data packet to be requested, which indicates that the service request is a request for requesting data service, determining that the service type corresponding to the service request is data service. The data services can be divided into two categories according to the size of the data packet to be requested, the big packet data service can be defined as the data service in which the size of the data packet to be requested is larger than or equal to a preset size, and the small packet data service can be defined as the data service in which the size of the data packet to be requested is smaller than the preset size. The preset size can be set by a person skilled in the art according to actual needs, and is not limited herein. For example, the preset size may be set to 50KB.

After determining the service type corresponding to the service request, the UE may be switched to the corresponding dedicated frequency band according to the service type, and the dedicated frequency band is used to carry the service of the specified service type, which may be specifically implemented by step S103 and step S104.

Those skilled in the art can set the frequency range of the second frequency band according to actual needs, and the setting is not limited herein. The first frequency band and the second frequency band are preferably ranges of frequency bands in which there is no overlapping area. Preferably, the frequency band with better coverage and better quality can be set as a second frequency band, and the second frequency band is used for bearing the VoLTE voice service and the packet data service, so that the voice quality of the VoLTE voice service can be effectively guaranteed.
For the F band, fig. 1b shows a schematic diagram of setting the first frequency band and the second frequency band, and as shown in fig. 1b, 1885MHz to 1905MHz in the F band may be set as the first frequency band, and 1905MHz to 1915MHz in the F band may be set as the second frequency band.

Fig. 2 is a flowchart illustrating a service hierarchical processing method for VoLTE voice service and data service according to another embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:
step S201, receiving a service request sent by a user equipment.
Step S202, according to the service request, determining the service type corresponding to the service request.
If the service request comprises VoLTE calling information, determining that the service type corresponding to the service request is VoLTE voice service; if the service request comprises the size of a data packet to be requested and the size of the data packet to be requested is smaller than the preset size, determining that the service type corresponding to the service request is a small packet data service; and if the service request comprises the size of the data packet to be requested and the size of the data packet to be requested is larger than or equal to the preset size, determining that the service type corresponding to the service request is a large packet data service.
Step S203, the user equipment is switched to the first frequency band, and the first frequency band is used to carry a service corresponding to the service request of the user equipment.
And if the service type is determined to be the big packet data service, switching the User Equipment (UE) to a first frequency band, and using the first frequency band to bear the service corresponding to the service request of the User Equipment (UE).
Step S204, the user equipment is switched to a second frequency band, and the second frequency band is used for bearing the service corresponding to the service request of the user equipment.
And if the service type is determined to be VoLTE voice service or small packet data service, switching the User Equipment (UE) to a second frequency band, and using the second frequency band to bear the service corresponding to the service request of the User Equipment (UE). Preferably, the frequency band with better coverage and better quality can be set as a second frequency band, and the second frequency band is used for bearing the VoLTE voice service and the packet data service, so that the voice quality of the VoLTE voice service can be effectively guaranteed. Specific settings for the first frequency band and the second frequency band in the F frequency band may be as shown in fig. 1 b.
The business layering processing method provided by the invention is realized by different frequency switching based on business types, and after the VoLTE voice user is switched into the second frequency band, the same frequency switching is kept during the conversation, so that the VoLTE user can be ensured to have good perception after the words are layered. The language number layering is mainly divided into flows of RRC access, default bearer establishment, QCI1 bearer establishment, conversation, hang-up and the like. After receiving a service request sent by User Equipment (UE), in an RRC (radio resource control) access stage, a base station cannot distinguish service types corresponding to the service request, and cannot realize language-number layering. And after RRC access, a user supporting VoLTE can establish QCI5/QCI9 default bearer, and when the user establishes QCI1 bearer, the service type corresponding to the service request is VoLTE voice service, different frequency switching based on the service type is triggered, user equipment UE is switched to a second frequency band, the second frequency band is used for bearing the VoLTE voice service of the user equipment UE, same frequency switching is kept, and language number layering is realized. The service type of the service required by the user next time after the user hangs up is unknown, so that the idle-state residence strategy after the user hangs up can be consistent with the residence strategy in the prior art, and no special designation is made here.
In the pilot frequency switching based on the service type, a trigger event corresponding to pilot frequency measurement can allow the highest priority QCI service established for User Equipment (UE) to be switched to a certain pilot frequency point, and a stop event corresponding to pilot frequency measurement can perform 3 seconds for measuring GAP without triggering switching; the trigger event corresponding to the inter-frequency handover may be an A4 event, and the stop event corresponding to the inter-frequency handover may be that the user equipment UE interrupts the QCI service allowing the handover.
Considering that the RSRP corresponding to the current frequency band may be low in the service processing process of data downloading or VoLTE voice call, in order to ensure that the service can be effectively processed, the present invention may also perform pilot frequency switching based on the covered RSRP. When the RSRP corresponding to the current frequency band is lower, pilot frequency handover is triggered, the user equipment in the frequency band with lower RSRP is handed over to another frequency band, and the other frequency band continues to carry the service corresponding to the service request of the handed over user equipment, which may be specifically implemented through steps S205 to S209.
Step S205, monitoring whether the current received power corresponding to the first frequency band meets a first pilot frequency switching condition; if yes, go to step S206; if not, go to step S205.
In the process of using the first frequency band to carry the big packet data service of the user equipment, whether the current receiving power corresponding to the first frequency band meets the first pilot frequency switching condition or not can be monitored in real time. If the current receiving power corresponding to the first frequency band is monitored to meet the first pilot frequency switching condition, executing step S206; if it is monitored that the current received power corresponding to the first frequency band does not meet the first pilot frequency switching condition, step S205 is executed to continue monitoring the current received power corresponding to the first frequency band.
In order to avoid that too many big packet data users occupy the resource of the second frequency band, the big packet data users need to be strictly controlled to occupy the second frequency band, and the switching difficulty from the first frequency band to the second frequency band can be increased by setting a pilot frequency switching event (for example, using an A5 event) from the first frequency band to the second frequency band, so that the big packet data service hardly meets the pilot frequency switching condition for switching to the second frequency band, and the big packet data users are controlled to switch into the second frequency band. In the present invention, the pilot frequency handover condition that needs to be satisfied for switching from the first frequency band to the second frequency band based on the covered RSRP is defined as a first pilot frequency handover condition, specifically, the first pilot frequency handover condition may be set as a handover condition that is difficult to achieve, for example, the first pilot frequency handover condition may be set as a current received power lower than-110 dBm (decibel milliwatt), and then if the current received power corresponding to the first frequency band is lower than-110 dBm, it is indicated that the signal strength of the first frequency band is relatively poor, in this case, step S206 is executed, the user equipment in the first frequency band is switched to the second frequency band, and the second frequency band is utilized to carry the packet data service of the user equipment.
Step S206, the user equipment is switched to the second frequency band, and the second frequency band is utilized to carry a service corresponding to the service request of the user equipment.
If it is monitored in step S205 that the current received power corresponding to the first frequency band meets the first pilot frequency switching condition, the user equipment in the first frequency band is switched to the second frequency band, and the second frequency band is used to carry the service corresponding to the service request of the user equipment. Those skilled in the art may set the number of the user equipments switching from the first frequency band to the second frequency band according to actual needs, which is not limited herein.
In the process of using the second frequency band to bear the VoLTE voice service or the packet data service of the user equipment, in order to better ensure the voice quality of the VoLTE voice service, the method delays the pilot frequency starting test, increases the switching difficulty from the second frequency band to the first frequency band, ensures that the VoLTE voice service hardly meets the pilot frequency switching condition of switching to the first frequency band, ensures that the same frequency switching is kept in the second frequency band, and improves the perception of the VoLTE user. In the present invention, a pilot frequency handover condition that needs to be satisfied for handover from the second frequency band to the first frequency band based on the covered RSRP is defined as a second pilot frequency handover condition.
Step S207, judging whether the current time reaches the pilot frequency starting time; if yes, go to step S208; if not, go to step S207.
Those skilled in the art may set the pilot frequency starting time according to actual needs, for example, the pilot frequency starting time may be set to a time corresponding to 10 seconds after the user equipment is switched to the second frequency band in step S204. Specifically, after the operation of switching the ue to the second frequency band is completed in step S204, a timer is started to determine whether the current time reaches the pilot frequency start time. If the current time reaches the pilot frequency starting time, executing step S208; if the current time does not reach the pilot frequency starting time, the step S207 is continuously executed.
Step S208, monitoring whether the current receiving power corresponding to the second frequency band meets a second pilot frequency switching condition; if yes, go to step S209; if not, go to step S208.
In step S207, it is monitored whether the current received power corresponding to the second frequency band meets the second pilot frequency switching condition when it is determined that the current time reaches the pilot frequency start time.
In order to better ensure the voice quality of the VoLTE voice service and avoid excessive VoLTE voice service from migrating to the second frequency band, the difficulty of switching from the second frequency band to the first frequency band may be increased, specifically, the second pilot frequency switching condition may be set to a switching condition that is difficult to achieve, for example, the second pilot frequency switching condition may be set to have a current receiving power lower than-110 dBm, and if the current receiving power corresponding to the second frequency band is lower than-110 dBm, it is indicated that the signal strength of the second frequency band is poor, in this case, step S209 is executed to switch the user equipment in the second frequency band to the first frequency band, and the first frequency band is used to carry the VoLTE voice service and the packet data service of the user equipment.
Step S209, the user equipment is switched to the first frequency band, and the first frequency band is used to carry a service corresponding to the service request of the user equipment.
If the current receiving power corresponding to the second frequency band meets the second pilot frequency switching condition, which is monitored and obtained in step S208, the user equipment is switched to the first frequency band, and the first frequency band is used to carry the service corresponding to the service request of the user equipment. Those skilled in the art may set the number of the user equipments switching from the second frequency band to the first frequency band according to actual needs, which is not limited specifically herein.
In the service processing process of data downloading or VoLTE voice communication and the like, the method and the system realize the language number layering and simultaneously carry out pilot frequency switching based on load balancing. Specifically, the implementation may be performed through steps S210 to S213, wherein steps S210 to S213 are not shown in fig. 2.
Step S210, monitoring whether the utilization rate of the physical resource block corresponding to the first frequency band exceeds a first preset threshold; if yes, go to step S211; if not, go to step S210.
In the process of using the first frequency band to carry the big packet data service of the user equipment, whether the physical resource block utilization ratio PRB corresponding to the first frequency band exceeds a first preset threshold can be monitored in real time. If it is monitored that the physical resource block utilization ratio PRB corresponding to the first frequency band exceeds a first preset threshold, executing step S211; if it is monitored that the physical resource block utilization ratio PRB corresponding to the first frequency band does not exceed the first preset threshold, step S210 is executed to continue monitoring the physical resource block utilization ratio PRB corresponding to the first frequency band. The physical resource block utilization ratio PRB corresponding to the first frequency band in the invention refers to a cell-level PRB.
Aiming at a big packet data user, the switching difficulty from a first frequency band to a second frequency band is increased by setting a first preset threshold so as to control the big packet data user to switch into the second frequency band, and the second frequency band is mainly used for bearing VoLTE voice service and small packet data service. Specifically, the first preset threshold may be set to 20%, and then step S211 is executed if the physical resource block utilization PRB corresponding to the first frequency band exceeds 20%.
Step S211, selecting a number of user equipments in accordance with a first preset number from the first frequency band as a first target user equipment, switching the first target user equipment to a second frequency band, and using the second frequency band to carry a service corresponding to the service request of the first target user equipment.
If it is monitored in step S210 that the utilization rate of the physical resource blocks corresponding to the first frequency band exceeds the first preset threshold, which indicates that the load of the first frequency band is heavy, the load balancing function is triggered, the user equipments whose number meets the first preset number are selected from the first frequency band as first target user equipments, the first target user equipments are switched to the second frequency band, and the second frequency band is used to carry the service corresponding to the service request of the first target user equipments. The skilled person can set the manner of selecting the user equipment and the first preset number according to actual needs. For example, a random algorithm may be used to randomly select a number of user equipments from the first frequency band that corresponds to the first preset number. For another example, when the first preset number is set to 10% of the maximum number of users in the cell, assuming that the maximum number of users in the cell is 1200, 120 user equipments need to be selected from the first frequency band as the first target user equipment.
Step S212, monitoring whether the utilization rate of the physical resource block corresponding to the second frequency band exceeds a second preset threshold; if yes, go to step S213; if not, go to step S212.
In the process of using the second frequency band to carry the VoLTE voice service or the packet data service of the user equipment, whether the physical resource block utilization ratio PRB corresponding to the second frequency band exceeds a second preset threshold can be monitored in real time. If it is monitored that the physical resource block utilization ratio PRB corresponding to the second frequency band exceeds a second preset threshold, executing step S213; if it is monitored that the physical resource block utilization ratio PRB corresponding to the second frequency band does not exceed the second preset threshold, step S212 is executed to continue monitoring the physical resource block utilization ratio PRB corresponding to the second frequency band. In the invention, the physical resource block utilization ratio PRB corresponding to the second frequency band refers to a cell-level PRB.
Aiming at VoLTE voice users and small packet data users, the difficulty of switching from a second frequency band to a first frequency band is increased by setting a second preset threshold, so that the first frequency band is mainly used for large packet data services. Specifically, the second preset threshold may be set to 20%, and if the physical resource block utilization PRB corresponding to the second frequency band exceeds 20%, step S213 is executed.
Step S213, selecting a number of user equipments in accordance with a second preset number from the second frequency band as a second target user equipment, switching the second target user equipment to the first frequency band, and using the first frequency band to carry a service corresponding to the service request of the second target user equipment.
If it is monitored in step S212 that the utilization rate of the physical resource block corresponding to the second frequency band exceeds the second preset threshold, which indicates that the load of the second frequency band is heavy, the load balancing function is triggered, the user equipments whose number meets the second preset number are selected from the second frequency band as second target user equipments, the second target user equipments are switched to the first frequency band, and the first frequency band is used to carry the service corresponding to the service request of the second target user equipments. The skilled person can set the manner of selecting the user equipment and the second preset number according to actual needs. For example, a random algorithm may be used to randomly select a number of user equipments from the second frequency band that corresponds to the second preset number. For another example, when the second preset number is set to 10% of the maximum number of users in the cell, assuming that the maximum number of users in the cell is 1200, 120 user equipments need to be selected from the second frequency band as the second target user equipment.
In order to verify the feasibility of the service layering processing method for the VoLTE voice service and the data service, the applicant applies the method to different scenes such as a road scene, an indoor weak field, a high-speed rail scene and the like for testing and evaluates the function effect of the speech layering. In a road scene, an indoor weak field and a high-speed rail scene, the second frequency band shown in fig. 1b is used for bearing the VoLTE voice service and the packet data service, and it is found that the MOS score is obviously improved, and the uplink packet loss rate and the downlink packet loss rate are both obviously reduced, thereby showing that the VoLTE voice quality is obviously improved.
According to the service layering processing method for the voice service and the data service of the VoLTE, the voice service and the data service of the VoLTE are layered through a language number layering cooperation strategy, a first frequency band is used for bearing a big packet of data service, a second frequency band is used for bearing the voice service and a small packet of data service which have small requirements on RB, overall distribution of the frequency bands is achieved, the frequency bands are fully utilized, gains are generated on voice in the dimensions of coverage, interference, switching and the like, the voice service is borne by the second frequency band, and the beneficial effects of fast deployment, small interference, excellent coverage and good perception can be achieved; in pilot frequency switching based on coverage RSRP and load balancing, through reasonable setting of switching conditions, not only can services be guaranteed to be effectively processed, but also the situation that excessive big packet data users occupy resources of a second frequency band is effectively avoided, so that the second frequency band is mainly used for bearing VoLTE voice services and small packet data services, the voice quality of the VoLTE voice services is effectively guaranteed, voice access is more smooth, and the perception of the VoLTE users is improved.
