Description

Pilot frequency switching method and device
Technical Field
The present application relates to the field of communications technologies, and in particular, to a pilot frequency switching method and apparatus.
Background
In a 5G network, after a terminal device accesses an access network device of a first frequency point, a slicing service is established on a frequency band corresponding to the first frequency point. In this case, if the terminal device needs to initiate a new slicing service, the terminal device needs to determine whether the frequency point required by the new slicing service is the first frequency point. When the frequency point required by the second slicing service is not the first frequency point, the terminal device may refuse to establish the second slicing service, so that the terminal device cannot establish a new slicing service.
Disclosure of Invention
The application provides a pilot frequency switching method and a pilot frequency switching device, which can solve the problem that a terminal device cannot establish a pilot frequency slicing service due to the fact that the pilot frequency switching cannot be triggered based on the frequency point requirement level of the slicing service.
In order to achieve the purpose, the technical scheme is as follows:
in a first aspect, the present application provides a method for inter-frequency handover, including: the access network equipment acquires a first frequency point and a first frequency point demand grade of a first slicing service, and a second frequency point demand grade of a second slicing service; the first slicing service is a slicing service established by the terminal equipment, and the second slicing service is a slicing service to be established by the terminal equipment; if the first frequency point is different from the second frequency point, the access network equipment determines the level of the first frequency point requirement level and the level of the second frequency point requirement level; if the first frequency point demand level is lower than the second frequency point demand level, the access network equipment sends first indication information to the terminal equipment; the first indication information is used for indicating the terminal equipment to measure the carrier wave of the second frequency point, and carrying out pilot frequency switching when the carrier wave of the second frequency point meets the switching condition.
Based on the above technical scheme, according to the pilot frequency switching method provided by the embodiment of the application, the access network device not only obtains the required frequency points of the first slicing service and the second slicing service of the terminal device, but also obtains the frequency point required levels of the first slicing service and the second slicing service, so that the access network device determines to perform pilot frequency switching on the terminal device under the condition that the first frequency point is different from the second frequency point and the first frequency point required level is lower than the second frequency point required level by comparing the frequency point required levels of the first slicing service and the second slicing service. That is to say, under the condition that the first frequency point is different from the second frequency point and the requirement level of the first frequency point is lower than the requirement level of the second frequency point, the first slicing service is not only established at the corresponding frequency point but also established at other frequency points, and the requirement level of the second slicing service at the second frequency point is higher than the requirement level of the first slicing service at the first frequency point, the establishment of the second slicing service needs to be preferentially ensured.
In one possible implementation, the frequency point requirement level includes: a first level, a second level, and a third level; the first level is higher than the second level, and the second level is higher than the third level; the first grade is used for representing that the slicing service is necessarily established at a corresponding frequency point; the second grade is used for representing that the slicing service is preferentially established at the corresponding frequency point; and the third grade is used for representing the establishment of the slicing service at any frequency point. In the implementation mode, data preparation is provided for the subsequent access network equipment to compare the first frequency point demand grade and the second frequency point demand grade, so that the access network equipment can trigger pilot frequency switching based on the frequency point demand grade of the slice service, and further the terminal equipment can establish the slice service of the pilot frequency in a proper scene.
In a possible implementation manner, if the first frequency point and the second frequency point are the same or different, the second frequency point requirement level is not the first level, and the first frequency point requirement level is higher than or equal to the second frequency point requirement level, the access network device determines to establish the second slice service at the first frequency point. In this implementation manner, the access network device determines to establish the second slicing service at the first frequency point when the first frequency point is the same as the second frequency point, or the first frequency point is different from the second frequency point, the second frequency point requirement level is not the first level, and the first frequency point requirement level is higher than or equal to the second frequency point requirement level. Under the two conditions, the access network equipment can establish the second slicing service without switching frequency points, so that the terminal equipment can normally establish the first slicing service and the second slicing service.
In a possible implementation manner, if the first frequency point and the second frequency point are different, and the first frequency point requirement level and the second frequency point requirement level are both first levels, the access network device sends second indication information to the terminal device; the second indication information is used for representing the second slice service establishment failure. In this implementation manner, the first frequency point and the second frequency point are different, and the first frequency point requirement level and the second frequency point requirement level are both first levels, and the access network device needs to preferentially ensure the continuity of the first slice service and cannot switch to the second frequency point.
In a second aspect, the present application provides an inter-frequency handover apparatus, including: a communication unit and a processing unit; the communication unit is used for acquiring a first frequency point and a first frequency point demand grade of a first slicing service, and a second frequency point demand grade of a second slicing service; the first slicing service is a slicing service established by the terminal equipment, and the second slicing service is a slicing service to be established by the terminal equipment; if the first frequency point is different from the second frequency point, the processing unit is used for determining the levels of the first frequency point requirement level and the second frequency point requirement level; if the first frequency point demand level is lower than the second frequency point demand level, the communication unit is further used for sending first indication information to the terminal equipment; the first indication information is used for indicating the terminal equipment to measure the carrier wave of the second frequency point, and carrying out pilot frequency switching when the carrier wave of the second frequency point meets the switching condition.
In one possible implementation, the frequency point requirement level includes: a first level, a second level, and a third level; the first level is higher than the second level, and the second level is higher than the third level; the first grade is used for representing that the slicing service is necessarily established at a corresponding frequency point; the second grade is used for representing that the slicing service is preferentially established at the corresponding frequency point; and the third level is used for representing the establishment of the slicing service at any frequency point.
In one possible implementation, the processing unit is further configured to: and if the first frequency point is the same as the second frequency point or the first frequency point is different from the second frequency point, the second frequency point requirement grade is not the first grade, and the first frequency point requirement grade is higher than or equal to the second frequency point requirement grade, determining that a second slicing service is established at the first frequency point.
In one possible implementation, the communication unit is further configured to: if the first frequency point and the second frequency point are different and the first frequency point requirement level and the second frequency point requirement level are both the first level, sending second indication information to the terminal equipment; the second indication information is used for representing the second slice service establishment failure.

One, different frequency switching
The pilot frequency switching refers to switching between access network devices in different frequency bands by a terminal device.
Typically, the triggering of inter-frequency handover is based on coverage. In the inter-frequency handover based on coverage, different handover events (e.g., A3 event, a4 event, and a5 event) correspond to different trigger conditions.
The triggering condition of the A3 event is that the network quality of the co-frequency adjacent cell is higher than that of the serving cell. When the cell information meeting the A3 event triggering condition is reported, the source access network equipment starts the same-frequency switching request.
The triggering condition of the a4 event is that the network quality of the inter-frequency adjacent cell is higher than a first preset threshold. When the cell information meeting the A4 event triggering condition is reported, the source access network equipment starts an inter-frequency handover request.
The triggering condition of the a5 event is that the network quality of the serving cell is lower than a second preset threshold, and the quality of the inter-frequency neighboring cell is higher than a third preset threshold. When the cell information meeting the A5 event triggering condition is reported, the source access network equipment starts an inter-frequency handover request.
It should be noted that under different scenarios, different event triggering conditions may be applied as the conditions for triggering inter-frequency handover.
For example, in a scenario of overlapping coverage, a scenario of switching between different frequency bins with the same bandwidth, or a scenario of switching between different frequency bins in the same frequency band, the trigger condition of the a3 event may be used as the trigger condition of the different frequency switching.
For another example, in a general scenario (for example, a weak coverage scenario), the trigger condition of the a4 event or the trigger condition of the a5 event may be used as the trigger condition of inter-frequency handover.
For another example, in a scenario where there is no special demand for serving cell signals, the trigger condition of the A3 event or the trigger condition of the a4 event may be used as the trigger condition of inter-frequency handover.

At present, in a 5G network, after a terminal device accesses an access network device at a first frequency point, a slicing service is established on a frequency band corresponding to the first frequency point. In this case, if the terminal device needs to initiate a new slicing service, the terminal device needs to determine whether the frequency point required by the new slicing service is the first frequency point. When the frequency point required by the second slicing service is not the first frequency point, the terminal device may refuse to establish the second slicing service because the first frequency point cannot satisfy a Service Level Agreement (SLA) requirement of the second slicing service, so that the terminal device cannot establish a new slicing service.
Illustratively, the terminal device has established an Ultra Reliable Low Latency Communication (URLLC) service (denoted as service 1) in the 3.5G frequency band. In this case, if the terminal device needs to establish another URLLC service (denoted as service 2) in the 2.1G frequency band, the terminal device will refuse to switch because the service 1 is different from the service 2 in demand frequency points, and at the same time refuse to establish the service 2, because the terminal device cannot guarantee the SLA (for example, delay requirement) of the service 2.
In addition, under the above situation, when the frequency point required by the second slicing service is not the first frequency point, the terminal device may directly switch to the second frequency point under the condition that the first slicing service cannot be continued to the second frequency point, and then establish the second slicing service at the second frequency point, but this will cause the original first slicing service to be interrupted, which will greatly reduce the user experience.
Illustratively, the terminal device has established a URLLC service (denoted as U1) in the 3.5G band. In this case, if the terminal device needs to establish another URLLC service (denoted as U2) in the 2.1G frequency band, the terminal device directly switches to the 2.1G frequency band due to the difference between the required frequency points of the U1 and the U2, and further establishes U2 in the 2.1G frequency band, but may also cause U1 to be interrupted.
In order to solve the problems in the prior art, an embodiment of the present application provides a pilot frequency switching method, which can trigger pilot frequency switching based on a frequency point requirement level of a slice service, so that a terminal device can establish the slice service of pilot frequency. As shown in fig. 3, the method includes:
s301, the access network equipment acquires a first frequency point and a first frequency point demand level of a first slicing service, and a second frequency point demand level of a second slicing service.
The first slicing service is a slicing service established by the terminal device, and the second slicing service is a slicing service to be established by the terminal device.
It should be noted that the first frequency point and the second frequency point may be the same or different.
For example, in a scenario where the first frequency point is different from the second frequency point, the first slice service may be a slice service #1 that has been established by the terminal device within the 3.5G frequency band. The second slicing service may be a slicing service #2 to be established by the terminal device in the 2.1G frequency band.
Further exemplarily, in a scenario where the first frequency point is the same as the second frequency point, the first slicing service is a slicing service #3 that has been established by the terminal device within the 3.5G frequency band. The second slicing service is a slicing service #4 to be established by the terminal device in the 3.5G frequency band.
In one possible implementation, the frequency point requirement level includes: a first level, a second level, and a third level. The first level is higher than the second level, and the second level is higher than the third level.
In one possible implementation, the first level may be represented by "Only". The second level may be denoted by "Preferred". The third level may be represented by "no configuration".
The first grade is used for representing that the slicing service can only be established at the corresponding frequency point.
It should be noted that the slicing service with the frequency point requirement level as the first level can only be established at the corresponding frequency point, but cannot be established at other frequency points. If the terminal device switches to another frequency point (i.e. a frequency point not corresponding to the slicing service of the first level) while the slicing service of the first level is already established, the slicing service of the first level will be interrupted.
And the second level is used for representing that the slice service is preferentially established at the corresponding frequency point.
It should be noted that the slicing service with the frequency point requirement level as the second level is preferentially established at the corresponding frequency point, that is, if the slicing service of the second level is established at the corresponding frequency point, the performance or stability of the slicing service of the second level is better, but the slicing service of the second level may also be established at other frequency points. When the second-level slicing service is established at the corresponding frequency point, the performance or stability of the slicing service is generally better than that of the slicing service established at other frequency points. If the terminal device switches to another frequency point (i.e. a frequency point not corresponding to the second level of slicing service) under the condition that the terminal device has already established the second level of slicing service, the terminal device may reestablish the second level of slicing service at the another frequency point to maintain the service continuity thereof.
And the third level is used for representing that the slicing service can be established at any frequency point.
It should be noted that the slicing service with the frequency point requirement level of the third level can be established at any frequency point, that is, the slicing service with the second level has no special requirement on the frequency point, and can be established at any frequency point. If the terminal device switches to another frequency point (i.e. a frequency point not corresponding to the third level of slicing service) under the condition that the terminal device has already established the third level of slicing service, the terminal device may reestablish the third level of slicing service at the another frequency point to maintain the service continuity thereof.
S302, if the first frequency point is different from the second frequency point, the access network equipment determines the level of the first frequency point requirement level and the level of the second frequency point requirement level.
As a possible implementation manner, the specific implementation process of S302 may be: the access network equipment compares whether the first frequency point is the same as the second frequency point, and then compares the first frequency point requirement grade with the second frequency point requirement grade under the condition that the first frequency point is different from the second frequency point.
And S303, if the first frequency point requirement level is less than the second frequency point requirement level, the access network equipment sends first indication information to the terminal equipment. Correspondingly, the terminal equipment receives the first indication information from the access network equipment.
The first indication information is used for indicating the terminal equipment to measure the carrier wave of the second frequency point, and the pilot frequency switching is carried out when the carrier wave of the second frequency point meets the switching condition.
In one example, the first frequency point of the first slice service is 2.1G, and the first demand frequency point level is the second level. The second frequency point of the second slicing service is 3.5G, and the level of the second demand frequency point is the first level. The access network equipment compares the first frequency point with the second frequency point, determines that the first frequency point is different from the second frequency point, compares the first frequency point demand grade with the second frequency point demand grade, and determines that the first frequency point demand grade is lower than the second frequency point demand grade. In this case, inter-frequency handover to the terminal device is determined.
In another example, the first frequency point of the first slice service is 2.1G, and the first demand frequency point level is the third level. The second frequency point of the second slicing service is 3.5G, and the level of the second required frequency point is a second level. The access network equipment compares the first frequency point with the second frequency point, determines that the first frequency point is different from the second frequency point, compares the first frequency point demand grade with the second frequency point demand grade, and determines that the first frequency point demand grade is lower than the second frequency point demand grade. In this case, inter-frequency handover to the terminal device is determined.
In another example, the first frequency point of the first slice service is 2.1G, and the first demand frequency point level is the third level. The second frequency point of the second slice service is 3.5G, and the level of the second required frequency point is the first level. The access network equipment compares the first frequency point with the second frequency point, determines that the first frequency point is different from the second frequency point, compares the first frequency point demand grade with the second frequency point demand grade, and determines that the first frequency point demand grade is lower than the second frequency point demand grade. In this case, inter-frequency handover to the terminal device is determined.
It should be noted that there may be two or more first slice services. In this case, the slice requirement level of the second slice service needs to be higher than the first frequency point requirement level of each of the two or more first slice services, and the access network device will determine to perform inter-frequency handover on the terminal device.
Illustratively, there are two first slice services (denoted as a1 and a 2). The first frequency point of A1 is 2.1G, and the first demand frequency point level is a third level. The first frequency point of A2 is 2.1G, and the first demand frequency point level is a second level. The second frequency point of the second slicing service is 3.5G, and the level of the second demand frequency point is the first level. The access network equipment compares the first frequency point with the second frequency point, determines that the first frequency point is different from the second frequency point, compares the first frequency point demand grade of A1, the first frequency point demand grade of A2 and the second frequency point demand grade, and determines that the first frequency point demand grade of A1 and the first frequency point demand grade of A2 are all lower than the second frequency point demand grade. In this case, inter-frequency handover to the terminal device is determined.
As a possible implementation manner, a specific implementation process of sending, by the access network device to the terminal device in S303, the first indication information may be: the access network equipment sends the first indication information to the terminal equipment, and correspondingly, the terminal equipment receives the first indication information from the access network equipment. After receiving the first indication information, the terminal device measures the carrier of the second frequency point, and when the carrier of the second frequency point meets the switching triggering condition, the terminal device sends a measurement report including the carrier information of the second frequency point to the access network device, and after receiving the measurement report, the access network device triggers the terminal device to perform pilot frequency switching, and the current access network device is switched to the access network device corresponding to the second frequency point.
It should be noted that the above-mentioned switching trigger condition may be a trigger condition of an A3 event, or a trigger condition of an a4 event, or a trigger condition of an a5 event.
It should be noted that, when the terminal device receives the first indication information sent by the access network device and measures the carrier of the second frequency point according to the first indication information, if the carrier of the second frequency point does not satisfy the handover trigger condition, the terminal device sends a carrier corresponding message to the access network device to notify the access network device of no inter-frequency handover.
For example, in a case that the handover triggering condition is a triggering condition of an a4 event, if the terminal device measures that the carrier of the second frequency point does not meet the triggering condition of the a4 event, the terminal device sends a carrier corresponding message to the access network device to notify that the access network device cannot perform inter-frequency handover.
The application provides a pilot frequency switching method, access network equipment not only acquires the required frequency points of a first slicing service and a second slicing service of terminal equipment, but also acquires the frequency point required levels of the first slicing service and the second slicing service, so that the access network equipment determines to perform pilot frequency switching on the terminal equipment under the conditions that the first frequency point is different from the second frequency point and the first frequency point required level is lower than the second frequency point required level by comparing the frequency point required levels of the first slicing service and the second slicing service.
That is to say, under the condition that the first frequency point is different from the second frequency point and the demand level of the first frequency point is lower than the demand level of the second frequency point, the first slicing service is not only established at the corresponding frequency point but also established at other frequency points, and the demand level of the second slicing service at the second frequency point is higher than the demand level of the first slicing service at the first frequency point, the establishment of the second slicing service needs to be preferentially ensured.
In one possible implementation, as shown in fig. 4, after S301, the method may further include the following S401.
S401, if the first frequency point is the same as the second frequency point, or the first frequency point is different from the second frequency point, the second frequency point requirement level is not the first level, and the first frequency point requirement level is higher than or equal to the second frequency point requirement level, the access network equipment determines to establish a second slicing service at the first frequency point.
In one example, the first frequency point of the first slice service is 2.1G, and the first demand frequency point level is a first level. The second frequency point of the second slicing service is 2.1G, and the level of the second required frequency point is the first level. And the access network equipment compares the first frequency point with the second frequency point and determines that the first frequency point is the same as the second frequency point. In this case, the access network device determines to establish the second slice service at the first frequency point.
In another example, the first frequency point of the first slice service is 2.1G, and the first demand frequency point level is a first level. The second frequency point of the second slicing service is 3.5G, and the level of the second required frequency point is a second level. The access network equipment compares the first frequency point with the second frequency point, and determines that the first frequency point is different from the second frequency point, the second frequency point requirement level is a second level (namely the second frequency point requirement level is not a first level), and the first frequency point requirement level is higher than the second frequency point requirement level (namely the first level is higher than the second level). In this case, the access network device determines to establish the second slice service at the first frequency point.
In another example, the first frequency point of the first slice service is 2.1G, and the first demand frequency point level is a first level. The second frequency point of the second slice service is 3.5G, and the level of the second required frequency point is a third level. The access network equipment compares the first frequency point with the second frequency point, and determines that the first frequency point is different from the second frequency point, the second frequency point requirement level is a third level (namely the second frequency point requirement level is not the first level), and the first frequency point requirement level is higher than the second frequency point requirement level (namely the first level is higher than the third level). In this case, the access network device determines to establish the second slice service at the first frequency point.
It should be noted that the terminal device may currently establish two or more slice services at the first frequency point (that is, the terminal device currently has two or more first slice services). In this case, the first frequency points of the two or more first slicing services and the second frequency points of the second slicing service need to be the same, and the access network device may determine to establish the second slicing service at the first frequency points.
Illustratively, there are two first slice services (denoted as a5 and a 6). The first frequency point of A5 is 2.1G, and the first demand frequency point level is a first level. The first frequency point of A6 is 2.1G, and the first demand frequency point level is a second level. The second frequency point of the second slicing service is 2.1G, and the level of the second required frequency point is a second level. The access network equipment compares the first frequency point of A5, the first frequency point of A6 and the second frequency point, and determines that the first frequency point of A5, the first frequency point of A6 and the second frequency point are the same. In this case, the access network device determines to establish the second slice service at the first frequency point.
It should be noted that, in a situation that the terminal device may currently establish two or more slicing services at the first frequency point (that is, the terminal device currently has two or more first slicing services), the first frequency point is different from the second frequency point, a slicing requirement level of any one of the two or more first slicing services is higher than or equal to a second frequency point requirement level in the second slicing service, and the second frequency point requirement level is not the first level, the access network device determines to establish the second slicing service at the first frequency point.
Illustratively, there are two first slice services (denoted as A3 and a 4). The first frequency point of A3 is 2.1G, and the first demand frequency point level is a first level. The first frequency point of A2 is 2.1G, and the first demand frequency point level is a second level. The second frequency point of the second slicing service is 3.5G, and the level of the second required frequency point is a second level. The access network equipment determines that the first frequency point is different from the second frequency point, and the second frequency point demand level is a second level (namely the second frequency point demand level is not a first level), and then compares the first frequency point demand level of the A3, the first frequency point demand level of the A4 and the second frequency point demand level, and determines that the first frequency point demand level of the A3 is higher than the second frequency point demand level, and the first frequency point demand level of the A4 is equal to the second frequency point demand level. In this case, the access network device determines to establish the second slice service at the first frequency point.
The application provides a pilot frequency switching method, wherein under the condition that a first frequency point is the same as a second frequency point or the first frequency point is different from the second frequency point, the requirement grade of the second frequency point is not a first grade, and the requirement grade of the first frequency point is higher than or equal to the requirement grade of the second frequency point, an access network device determines to establish a second slicing service at the first frequency point. Under the two conditions, the access network equipment can establish the second slicing service without switching frequency points, so that the terminal equipment can normally establish the first slicing service and the second slicing service.
In one possible implementation, as shown in fig. 5, after S301, the method may further include the following S501.
S501, if the first frequency point and the second frequency point are different and the first frequency point requirement level and the second frequency point requirement level are both the first level, the access network equipment sends second indication information to the terminal equipment. Correspondingly, the terminal equipment receives the second indication information from the access network equipment.
And the second indication information is used for representing the establishment failure of the second slice service.
In one example, the first frequency point of the first slice service is 2.1G, and the first demand frequency point level is a first level. The second frequency point of the second slicing service is 3.5G, and the level of the second demand frequency point is the first level. The access network equipment compares the first frequency point with the second frequency point, determines that the first frequency point is different from the second frequency point, compares the first frequency point demand grade with the second frequency point demand grade, and determines that the first frequency point demand grade and the second frequency point demand grade are both the first grade. In this case, it is determined not to perform inter-frequency handover on the terminal device.
The application provides a pilot frequency switching method, wherein a first frequency point and a second frequency point are different, the first frequency point requirement level and the second frequency point requirement level are both first levels, access network equipment needs to preferentially ensure the continuity of a first slicing service and cannot switch to the second frequency point, but under the condition, the second slicing service cannot be established at the first frequency point, and then the access network equipment sends second indication information to terminal equipment so as to ensure the continuity of the first slicing service.
