本申请涉及通信技术领域，尤其涉及一种异频切换方法及装置。The present application relates to the field of communication technologies, and in particular, to an inter-frequency handover method and device.
背景技术Background technique
在5G网络中，终端设备接入第一频点的接入网设备之后，将在第一频点对应的频段上建立切片业务。在该情况下，如果终端设备需要发起新的切片业务，则终端设备需要确定新的切片业务需求的频点是否是上述第一频点。当第二切片业务需求的频点不是第一频点时，终端设备将可能会拒绝第二切片业务的建立，导致终端设备无法建立新的切片业务。In the 5G network, after the terminal device accesses the access network device of the first frequency point, a slice service will be established on the frequency band corresponding to the first frequency point. In this case, if the terminal device needs to initiate a new slice service, the terminal device needs to determine whether the frequency point required by the new slice service is the above-mentioned first frequency point. When the frequency point required by the second slice service is not the first frequency point, the terminal device may refuse the establishment of the second slice service, so that the terminal device cannot establish a new slice service.
发明内容SUMMARY OF THE INVENTION
本申请提供一种异频切换方法及装置，能够解决由于不能基于切片业务的频点需求等级触发异频切换导致终端设备不能建立异频的切片业务的问题。The present application provides an inter-frequency handover method and device, which can solve the problem that a terminal device cannot establish an inter-frequency slice service because the inter-frequency handover cannot be triggered based on the frequency point requirement level of the slice service.
为达到上述目的，本申请采用如下技术方案：To achieve the above object, the application adopts the following technical solutions:
第一方面，本申请提供一种异频切换方法，该方法包括：接入网设备获取第一切片业务的第一频点和第一频点需求等级，以及第二切片业务的第二频点和第二频点需求等级；其中，第一切片业务为终端设备已建立的切片业务，第二切片业务为终端设备待建立的切片业务；若第一频点和第二频点不同，则接入网设备确定第一频点需求等级和第二频点需求等级的高低；若第一频点需求等级低于第二频点需求等级，则接入网设备向终端设备发送第一指示信息；第一指示信息用于指示终端设备测量第二频点的载波，并在第二频点的载波满足切换条件时进行异频切换。In a first aspect, the present application provides an inter-frequency handover method. The method includes: an access network device obtains a first frequency point and a first frequency point demand level of a first slice service, and a second frequency point of the second slice service. point and the second frequency point demand level; wherein, the first slice service is the slice service established by the terminal equipment, and the second slice service is the slice service to be established by the terminal equipment; if the first frequency point and the second frequency point are different, The access network equipment determines the level of the first frequency point demand level and the second frequency point demand level; if the first frequency point demand level is lower than the second frequency point demand level, the access network equipment sends the first indication to the terminal equipment. information; the first indication information is used to instruct the terminal device to measure the carrier of the second frequency point, and perform inter-frequency switching when the carrier of the second frequency point satisfies the switching condition.
基于上述技术方案，本申请实施例提供的异频切换方法，接入网设备不仅获取终端设备第一切片业务和第二切片业务的需求频点，还获取第一切片业务和第二切片业务的频点需求等级，这样接入网设备通过对比第一切片业务和第二切片业务的频点需求等级，将会在第一频点与第二频点不同，且第一频点需求等级低于第二频点需求等级的情况下，确定对终端设备进行异频切换。也就是说，在第一频点与第二频点不同，且第一频点需求等级低于第二频点需求等级的情况下，第一切片业务不是只能在对应频点建立，可以在其他频点上建立，而第二切片业务对第二频点的需求等级高于第一切片业务对第一频点的需求等级，则需要优先保证第二切片业务的建立，因此，接入网设备在该情况下确定对终端设备进行异频切换，以使得终端设备切换到第二频点上，进而终端设备可以在第二频点建立第二切片业务，在保证第二切片业务的建立的情况下，还保持了第一切片业务的延续性。Based on the above technical solutions, in the inter-frequency handover method provided by the embodiments of the present application, the access network device not only obtains the required frequency points of the first slice service and the second slice service of the terminal device, but also obtains the first slice service and the second slice service. The frequency demand level of the service, so that the access network equipment will compare the frequency demand level of the first slice service and the second slice service, and the first frequency point will be different from the second frequency point, and the first frequency point needs When the level is lower than the second frequency point demand level, it is determined to perform inter-frequency handover on the terminal device. That is to say, when 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 slice service can not only be established at the corresponding frequency point, but can Established on other frequency points, but the demand level of the second slicing service for the second frequency point is higher than that of the first slicing service for the first frequency point, the establishment of the second slicing service needs to be prioritized. In this case, the network access device determines to perform inter-frequency handover on the terminal device, so that the terminal device switches to the second frequency point, so that the terminal device can establish the second slice service at the second frequency point, and ensure the second slice service. In the case of establishment, the continuity of the first slice business is also maintained.
在一种可能的实现方式中，频点需求等级包括：第一等级、第二等级、以及第三等级；第一等级高于第二等级，第二等级高于第三等级；其中，第一等级用于表征切片业务必要在对应频点建立；第二等级用于表征切片业务优先在对应频点建立；第三等级用于表征切片业务在任一频点建立。在该种实现方式中，为后续接入网设备对比第一频点需求等级和第二频点需求等级提供数据准备，以便接入网设备可以基于切片业务的频点需求等级触发异频切换，进而使得终端设备可以在适合的场景下建立异频的切片业务。In a possible implementation manner, the frequency point requirement levels include: 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; wherein the first level The level is used to indicate that the slice service must be established at the corresponding frequency point; the second level is used to indicate that the slice service is preferentially established at the corresponding frequency point; the third level is used to indicate that the slice service is established at any frequency point. In this implementation manner, data preparation is provided for the subsequent access network equipment to compare the first frequency point demand level with the second frequency point demand level, so that the access network equipment can trigger inter-frequency handover based on the frequency point demand level of the slice service, This enables the terminal device to establish an inter-frequency slicing service in a suitable scenario.

When the demand level is higher than or equal to the second frequency point, the access network device determines to establish the second slice service at the first frequency point. In the above two cases, the access network device can establish the second slice service without switching frequency points, so that the terminal device can normally establish the first slice service and the second slice service.
在一种可能的实现方式中，若第一频点和第二频点不同，且第一频点需求等级与第二频点需求等级均为第一等级，则接入网设备向终端设备发送第二指示信息；第二指示信息用于表征第二切片业务建立失败。在该种实现方式中，在第一频点与第二频点不同，且第一频点需求等级与第二频点需求等级均为第一等级，接入网设备需要优先保证第一切片业务的连续性，不能向第二频点进行切换，但是在该情况下，第二切片业务也无法在第一频点处建立，进而接入网设备向终端设备发送第二指示信息，以便于保证第一切片业务的延续性。In a possible implementation manner, if the first frequency point and the second frequency point are different, and the demand level of the first frequency point and the demand level of the second frequency point are both the first level, the access network device sends a message to the terminal device. second indication information; the second indication information is used to represent that the establishment of the second slice service fails. In this implementation, when the first frequency point is different from the second frequency point, and the first frequency point demand level and the second frequency point demand level are both the first level, the access network device needs to give priority to ensuring the first slice The continuity of the service cannot be switched to the second frequency point, but in this case, the second slice service cannot be established at the first frequency point, and then the access network device sends the second indication information to the terminal device to facilitate Guarantee the continuity of the first slice business.

以下，对本申请实施例涉及的名词进行解释，以方便读者理解。Below, the terms involved in the embodiments of the present application will be explained to facilitate the reader's understanding.
一、异频切换1. Inter-frequency switching
异频切换是指终端设备在不同频段的接入网设备之间进行切换。Inter-frequency handover refers to the handover of terminal equipment between access network equipment in different frequency bands.
通常情况下，异频切换的触发是基于覆盖进行的。基于覆盖的异频切换中，不同的切换事件(例如，A3事件、A4事件、以及A5事件)对应不同的触发条件。Usually, the triggering of inter-frequency handover is based on coverage. In coverage-based inter-frequency handover, different handover events (eg, A3 event, A4 event, and A5 event) correspond to different trigger conditions.
其中，A3事件的触发条件为同频邻区的网络质量高于服务小区的网络质量。在满足A3事件触发条件的小区信息被上报时，源接入网设备启动同频切换请求。The triggering condition of the A3 event is that the network quality of the same-frequency neighboring cell is higher than the network quality of the serving cell. When the cell information that satisfies the A3 event trigger condition is reported, the source access network device initiates an intra-frequency handover request.
A4事件的触发条件为异频邻区的网络质量高于第一预设门限。在满足A4事件触发条件的小区信息被上报时，源接入网设备启动异频切换请求。The trigger condition of the A4 event is that the network quality of the inter-frequency neighbor cell is higher than the first preset threshold. When the cell information that satisfies the A4 event trigger condition is reported, the source access network device initiates an inter-frequency handover request.
A5事件的触发条件为服务小区的网络质量低于第二预设门限，且异频邻区质量高于第三预设门限。在满足A5事件触发条件的小区信息被上报时，源接入网设备启动异频切换请求。The triggering condition of the A5 event is that the network quality of the serving cell is lower than the second preset threshold, and the quality of the inter-frequency neighbor cell is higher than the third preset threshold. When the cell information satisfying the triggering condition of the A5 event is reported, the source access network device initiates an inter-frequency handover request.
需要指出的是，在不同的场景下，可以应用不同的事件的触发条件作为触发异频切换的条件。It should be pointed out that in different scenarios, triggering conditions of different events may be applied as conditions for triggering inter-frequency handover.
例如，在交叠覆盖的场景下、在带宽相同的异频频点间切换的场景下、或者在相同频段内异频频点间切换的场景下，可以将A3事件的触发条件作为异频切换的触发条件。For example, in the scenario of overlapping coverage, in the scenario of switching between different frequency points with the same bandwidth, or in the scenario of switching between different frequency points within the same frequency band, the trigger condition of the A3 event can be used as the trigger for the inter-frequency switching. condition.
又例如，在一般场景(例如，弱覆盖场景)下，可以将A4事件的触发条件或者A5事件的触发条件作为异频切换的触发条件。For another example, in a general scenario (for example, a weak coverage scenario), the triggering condition of the A4 event or the triggering condition of the A5 event may be used as the triggering condition of the inter-frequency handover.
又例如，在对于服务小区信号没有特殊需求的场景下，可以将A3事件的触发条件或者A4事件的触发条件作为异频切换的触发条件。For another example, in a scenario where there is no special requirement for the serving cell signal, the triggering condition of the A3 event or the triggering condition of the A4 event may be used as the triggering condition of the inter-frequency handover.
二、SLA2. SLA
SLA是指客户与为客户提供服务的企业就服务的品质、水准、性能等方面所达成的双方共同认可的协议。SLA refers to the mutually recognized agreement reached by the customer and the enterprise providing services to the customer on the quality, standard and performance of the service.

目前，在5G网络中，终端设备接入第一频点的接入网设备之后，将在第一频点对应的频段上建立切片业务。在该情况下，如果终端设备需要发起新的切片业务，则终端设备需要确定新的切片业务需求的频点是否是上述第一频点。当第二切片业务需求的频点不是第一频点时，终端设备将可能会由于第一频点不能满足第二切片业务的服务协议级别(service level agreement，SLA)需求而拒绝第二切片业务的建立，导致终端设备无法建立新的切片业务。At present, in the 5G network, after the terminal device accesses the access network device of the first frequency point, a slice service will be established on the frequency band corresponding to the first frequency point. In this case, if the terminal device needs to initiate a new slice service, the terminal device needs to determine whether the frequency point required by the new slice service is the above-mentioned first frequency point. When the frequency required by the second slicing service is not the first frequency, the terminal device may reject the second slicing service because the first frequency cannot meet the service level agreement (SLA) requirement of the second slicing service is established, so that the terminal device cannot establish a new slice service.
示例性的，终端设备已经在3.5G频段建立了一种超高可靠超低时延通信(ultrareliable low latency communication，URLLC)业务(记为业务1)。在该情况下，如果终端设备需要在2.1G频段建立另一种URLLC业务(记为业务2)，则由于上述业务1与上述业务2的需求频点不同，终端设备将会因无法保证上述业务2的SLA(例如，时延要求)而拒绝切换，同时也拒绝业务2的建立。Exemplarily, the terminal device has established an ultra-reliable and ultra-low latency communication (ultrareliable low latency communication, URLLC) service (referred to as service 1) in the 3.5G frequency band. In this case, if the terminal equipment needs to establish another URLLC service (referred to as service 2) in the 2.1G frequency band, since the above-mentioned service 1 and the above-mentioned service 2 have different demand frequencies, the terminal equipment will be unable to guarantee the above-mentioned service. 2's SLA (eg, delay requirement) and rejects handover, and also rejects establishment of service 2.
另外，在上述情况下，当第二切片业务需求的频点不是第一频点时，终端设备还有可能会在第一切片业务不能延续至第二频点的情况下，直接向第二频点切换，进而在第二频点下建立第二切片业务，但是这将会导致原有的第一切片业务被中断，这样将会大幅度的降低用户的使用体验。In addition, in the above situation, when the frequency required by the second slice service is not the first frequency, the terminal device may directly send the second slice service to the second frequency if the first slice service cannot be extended to the second frequency. The frequency point is switched, and the second slice service is established under the second frequency point, but this will cause the original first slice service to be interrupted, which will greatly reduce the user experience.
示例性的，终端设备已经在3.5G频段建立了一种URLLC业务(记为U1)。在该情况下，如果终端设备需要在2.1G频段建立另一种URLLC业务(记为U2)，则由于上述U1与上述U2的需求频点不同，终端设备直接向2.1G频段切换，进而在2.1G频段下建立U2，但也会导致U1被中断。Exemplarily, the terminal device has established a URLLC service (denoted as U1) in the 3.5G frequency band. In this case, if the terminal equipment needs to establish another URLLC service (referred to as U2) in the 2.1G frequency band, the terminal equipment directly switches to the 2.1G frequency band because the required frequency points of the above U1 and U2 are different, and then in the 2.1G frequency band. U2 is established in the G-band, but it will also cause U1 to be interrupted.
为了解决上述现有技术中存在的问题，本申请实施例提出了一种异频切换方法，能够基于切片业务的频点需求等级触发异频切换，使得终端设备可以建立异频的切片业务。如图3所示，该方法包括：In order to solve the above problems in the prior art, the embodiment of the present application proposes an inter-frequency handover method, which can trigger inter-frequency handover based on the frequency point demand level of the slice service, so that the terminal device can establish the inter-frequency slice service. As shown in Figure 3, the method includes:
S301、接入网设备获取第一切片业务的第一频点和第一频点需求等级，以及第二切片业务的第二频点和第二频点需求等级。S301. The access network device acquires the first frequency point and the first frequency point demand level of the first slice service, and the second frequency point and the second frequency point demand level of the second slice service.
其中，第一切片业务为终端设备已建立的切片业务，第二切片业务为终端设备待建立的切片业务。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.
需要说明的是，第一频点与第二频点可以相同，也可以不同。It should be noted that the first frequency point and the second frequency point may be the same or different.
示例性的，在第一频点与第二频点不同的场景下，第一切片业务可以为终端设备在3.5G频段内已建立的切片业务#1。第二切片业务可以为终端设备在2.1G频段内待建立的切片业务#2。Exemplarily, in a scenario where the first frequency point is different from the second frequency point, the first slice service may be the slice service #1 established by the terminal device in the 3.5G frequency band. The second slice service may be slice service #2 to be established by the terminal device in the 2.1G frequency band.
又示例性的，在第一频点与第二频点相同的场景下，第一切片业务为终端设备在3.5G频段内已建立的切片业务#3。第二切片业务为终端设备在3.5G频段内待建立的切片业务#4。For another example, in a scenario where the first frequency point is the same as the second frequency point, the first slice service is the slice service #3 established by the terminal device in the 3.5G frequency band. The second slice service is slice service #4 to be established by the terminal device in the 3.5G frequency band.
一种可能的实现方式中，频点需求等级包括：第一等级、第二等级、以及第三等级。第一等级高于第二等级，第二等级高于第三等级。In a possible implementation manner, the frequency point demand 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.
一种可能的实现方式中，第一等级可以用“Only”表示。第二等级可以用“Preferred”表示。第三等级可以用“无配置”表示。In one possible implementation, the first level may be represented by "Only". The second level can be represented by "Preferred". The third level can be represented by "no configuration".
其中，第一等级用于表征切片业务只能在对应频点建立。Among them, the first level is used to represent that the slice service can only be established at the corresponding frequency point.
需要说明的是，频点需求等级为第一等级的切片业务是只能在对应的频点建立，在其他频点上无法建立。若是终端设备在已建立第一等级的切片业务的情况下，向另一频点(即不是第一等级的切片业务的对应频点)切换的话，将会导致第一等级的切片业务被中断。It should be noted that the slice service whose frequency point demand level is the first level can only be established on the corresponding frequency point, and cannot be established on other frequency points. If the terminal device switches to another frequency point (ie, not the corresponding frequency point of the first-level slicing service) when the first-level slicing service has been established, the first-level slicing service will be interrupted.
第二等级用于表征切片业务优先在对应频点建立。The second level is used to indicate that the slice service is preferentially established at the corresponding frequency point.
需要说明的是，频点需求等级为第二等级的切片业务是优先在对应的频点建立，也就是说第二等级的切片业务在对应频点建立的话，会使得第二等级的切片业务的性能或者稳定性更好，但是在其他频点上也可以建立。在对应频点建立第二等级的切片业务时，该切片业务的性能或稳定性通常优于在其他频点建立该切片业务的性能或稳定性。若是终端设备在已建立第二等级的切片业务的情况下，向另一频点(即不是第二等级的切片业务的对应频点)切换的话，终端设备可以在该另一频点重新建立该第二等级的切片业务以保持其业务延续性。It should be noted that the slicing service whose frequency point demand level is the second level is preferentially established at the corresponding frequency point, that is to say, if the second-level slicing service is established at the corresponding frequency point, the The performance or stability is better, but it can also be established at other frequencies. When a second-level slicing service is established at a corresponding frequency, the performance or stability of the slicing service is usually better than that of establishing the slicing service at other frequencies. If the terminal device switches to another frequency point (that is, not the corresponding frequency point of the second-level slicing service) when the second-level slicing service has been established, the terminal device can re-establish the The second-level slicing business to maintain its business continuity.
第三等级用于表征切片业务能够在任一频点建立。The third level is used to characterize that the slice service can be established at any frequency.
需要说明的是，频点需求等级为第三等级的切片业务是可以在任一频点建立，也就是说第二等级的切片业务对频点没有特殊要求，在任一频点下都可以建立。若是终端设备在已建立第三等级的切片业务的情况下，向另一频点(即不是第三等级的切片业务的对应频点)切换的话，终端设备可以在该另一频点重新建立该第三等级的切片业务以保持其业务延续性。It should be noted that the slicing service with the frequency demand level of the third level can be established at any frequency point, that is to say, the slicing service of the second level has no special requirements on the frequency point, and can be established at any frequency point. If the terminal device switches to another frequency point (that is, not the corresponding frequency point of the third-level slice service) when the third-level slicing service has been established, the terminal device can re-establish the slicing service at the other frequency point. The third-level slice business to maintain its business continuity.
S302、若第一频点和第二频点不同，则接入网设备确定第一频点需求等级和第二频点需求等级的高低。S302. If the first frequency point and the second frequency point are different, the access network device determines the level of the demand level of the first frequency point and the demand level of the second frequency point.
作为一种可能的实现方式，上述S302的具体实现过程可以为：接入网设备先对比第一频点和第二频点是否相同，在第一频点与第二频点不相同的情况下，接入网设备再对比第一频点需求等级和第二频点需求等级。As a possible implementation manner, the specific implementation process of the above S302 may be as follows: the access network device first compares whether the first frequency point and the second frequency point are the same, and if the first frequency point and the second frequency point are different , the access network device then compares the demand level of the first frequency point with the demand level of the second frequency point.
S303、若第一频点需求等级小于低于第二频点需求等级，则接入网设备向终端设备发送第一指示信息。相应的，终端设备接收来自于接入网设备的第一指示信息。S303. If the demand level of the first frequency point is lower than the demand level of the second frequency point, the access network device sends first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information from the access network device.
其中，第一指示信息用于指示终端设备测量第二频点的载波，并在第二频点的载波满足切换条件时进行异频切换。Wherein, the first indication information is used to instruct the terminal device to measure the carrier of the second frequency point, and perform inter-frequency switching when the carrier of the second frequency point satisfies the switching condition.
一种示例，第一切片业务的第一频点为2.1G，第一需求频点等级为第二等级。第二切片业务的第二频点为3.5G，第二需求频点等级为第一等级。接入网设备对比第一频点与第二频点，确定第一频点与第二频点不同，再对比第一频点需求等级与第二频点需求等级，确定第一频点需求等级低于第二频点需求等级。在该情况下，确定对终端设备进行异频切换。In an example, the first frequency point of the first slice service is 2.1G, and the first required frequency point level is the second level. The second frequency of the second slice service is 3.5G, and the second required frequency level is the first level. The access network device compares the first frequency point and the second frequency point, determines that the first frequency point is different from the second frequency point, and then compares the demand level of the first frequency point with the demand level of the second frequency point to determine the demand level of the first frequency point Lower than the second frequency point demand level. In this case, it is determined to perform inter-frequency handover on the terminal device.
又一种示例，第一切片业务的第一频点为2.1G，第一需求频点等级为第三等级。第二切片业务的第二频点为3.5G，第二需求频点等级为第二等级。接入网设备对比第一频点与第二频点，确定第一频点与第二频点不同，再对比第一频点需求等级与第二频点需求等级，确定第一频点需求等级低于第二频点需求等级。在该情况下，确定对终端设备进行异频切换。In another example, the first frequency point of the first slice service is 2.1G, and the first required frequency point level is the third level. The second frequency point of the second slice service is 3.5G, and the second demand frequency point level is the second level. The access network device compares the first frequency point and the second frequency point, determines that the first frequency point is different from the second frequency point, and then compares the demand level of the first frequency point with the demand level of the second frequency point to determine the demand level of the first frequency point Lower than the second frequency point demand level. In this case, it is determined to perform inter-frequency handover on the terminal device.
又一种示例，第一切片业务的第一频点为2.1G，第一需求频点等级为第三等级。第二切片业务的第二频点为3.5G，第二需求频点等级为第一等级。接入网设备对比第一频点与第二频点，确定第一频点与第二频点不同，再对比第一频点需求等级与第二频点需求等级，确定第一频点需求等级低于第二频点需求等级。在该情况下，确定对终端设备进行异频切换。In another example, the first frequency point of the first slice service is 2.1G, and the first required frequency point level is the third level. The second frequency of the second slice service is 3.5G, and the second required frequency level is the first level. The access network device compares the first frequency point and the second frequency point, determines that the first frequency point is different from the second frequency point, and then compares the demand level of the first frequency point with the demand level of the second frequency point to determine the demand level of the first frequency point Lower than the second frequency point demand level. In this case, it is determined to perform inter-frequency handover on the terminal device.
需要说明的，第一切片业务可能会存在两个或两个以上。在该情况下，第二切片业务的切片需求等级需要高于上述两个或两个以上的第一切片业务中的每个第一切片业务的第一频点需求等级，接入网设备将会确定对终端设备进行异频切换。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 first slice service in the above two or more first slice services, and the access network equipment Inter-frequency handover of terminal equipment will be determined.
示例性的，第一切片业务有两个(记为A1和A2)。A1的的第一频点为2.1G，第一需求频点等级为第三等级。A2的的第一频点为2.1G，第一需求频点等级为第二等级。第二切片业务的第二频点为3.5G，第二需求频点等级为第一等级。接入网设备对比第一频点与第二频点，确定第一频点与第二频点不同，再对比上述A1的第一频点需求等级、上述A2的第一频点需求等级、以及第二频点需求等级，确定上述A1的第一频点需求等级和上述A2的第一频点需求等级均低于第二频点需求等级。在该情况下，确定对终端设备进行异频切换。Exemplarily, there are two first slice services (denoted as A1 and A2). The first frequency point of A1 is 2.1G, and the first demand frequency point level is the third level. The first frequency point of A2 is 2.1G, and the first demand frequency point level is the second level. The second frequency of the second slice service is 3.5G, and the second required frequency level is the first level. The access network device compares the first frequency point and the second frequency point, determines that the first frequency point is different from the second frequency point, and then compares the first frequency point demand level of the above A1, the first frequency point demand level of the above A2, and For the second frequency point demand level, it is determined that the first frequency point demand level of A1 and the first frequency point demand level of A2 are both lower than the second frequency point demand level. In this case, it is determined to perform inter-frequency handover on the terminal device.
作为一种可能的实现方式，上述S303中接入网设备向终端设备发送第一指示信息的具体实现过程可以为：接入网设备向终端设备发送第一指示信息，相应的，终端设备接收来自接入网设备的第一指示信息。终端设备在接收到第一指示信息之后，测量第二频点的载波，在第二频点的载波满足切换触发条件时，终端设备向接入网设备发送包括第二频点的载波信息的测量报告，接入网设备在接收到测量报告之后，触发终端设备进行异频切换，由当前的接入网设备切换至第二频点对应的接入网设备。As a possible implementation manner, the specific implementation process for the access network device to send the first indication information to the terminal device in the above S303 may be: the access network device sends the first indication information to the terminal device, and accordingly, the terminal device receives the first indication information from the terminal device. The first indication information of the access network device. 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 handover trigger condition, the terminal device sends the measurement including the carrier information of the second frequency point to the access network device After receiving the measurement report, the access network device triggers the terminal device to perform inter-frequency handover, and the current access network device switches to the access network device corresponding to the second frequency point.
需要指出的是，上述切换触发条件可以为A3事件的触发条件、或者A4事件的触发条件、或者A5事件的触发条件。It should be noted that the above switching trigger condition may be the trigger condition of the A3 event, or the trigger condition of the A4 event, or the trigger condition of the A5 event.
需要说明的是，在终端设备接收到接入网设备发送的第一指示信息，并根据第一指示信息测量第二频点的载波的情况下，若第二频点的载波不满足切换触发条件，则终端设备向接入网设备发送载波相应消息，以通知接入网设备不异频切换。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 meet the handover trigger condition , the terminal device sends a carrier corresponding message to the access network device to notify the access network device not to switch between frequencies.
示例性的，在切换触发条件为A4事件的触发条件的情况下，终端设备若测量到第二频点的载波不满足A4事件的触发条件，则向接入网设备发送载波相应消息，以通知接入网设备无法进行异频切换。Exemplarily, when the handover trigger condition is the trigger condition of the A4 event, if the terminal device measures that the carrier of the second frequency point does not meet the trigger condition of the A4 event, it sends a carrier corresponding message to the access network device to notify Access network equipment cannot perform inter-frequency handover.
本申请提供了一种异频切换方法，接入网设备不仅获取终端设备第一切片业务和第二切片业务的需求频点，还获取第一切片业务和第二切片业务的频点需求等级，这样接入网设备通过对比第一切片业务和第二切片业务的频点需求等级，将会在第一频点与第二频点不同，且第一频点需求等级低于第二频点需求等级的情况下，确定对终端设备进行异频切换。The present application provides an inter-frequency handover method, in which the access network device not only obtains the demand frequency points of the first slicing service and the second slicing service of the terminal equipment, but also obtains the frequency point requirements of the first slicing service and the second slicing service In this way, by comparing the frequency demand level of the first slice service and the second slice service, the access network equipment will be different at the first frequency point and the second frequency point, and the demand level of the first frequency point is lower than that of the second frequency point. In the case of the frequency point demand level, it is determined to perform inter-frequency handover on the terminal equipment.
也就是说，在第一频点与第二频点不同，且第一频点需求等级低于第二频点需求等级的情况下，第一切片业务不是只能在对应频点建立，可以在其他频点上建立，而第二切片业务对第二频点的需求等级高于第一切片业务对第一频点的需求等级，则需要优先保证第二切片业务的建立，因此，接入网设备在该情况下确定对终端设备进行异频切换，以使得终端设备切换到第二频点上，进而终端设备可以在第二频点建立第二切片业务，在保证第二切片业务的建立的情况下，还保持了第一切片业务的延续性。That is to say, when 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 slice service can not only be established at the corresponding frequency point, but can Established on other frequency points, but the demand level of the second slicing service for the second frequency point is higher than that of the first slicing service for the first frequency point, the establishment of the second slicing service needs to be prioritized. In this case, the network access device determines to perform inter-frequency handover on the terminal device, so that the terminal device switches to the second frequency point, so that the terminal device can establish the second slice service at the second frequency point, and ensure the second slice service. In the case of establishment, the continuity of the first slice business is also maintained.
一种可能的实现方式中，如图4所示，在S301之后，该方法还可以包括以下S401。In a possible implementation manner, as shown in FIG. 4 , after S301 , the method may further include the following S401 .
S401、若第一频点和第二频点相同，或者第一频点和第二频点不同，第二频点需求等级不为第一等级，且第一频点需求等级高于或等于第二频点需求等级，则接入网设备确定在第一频点建立第二切片业务。S401. If the first frequency point and the second frequency point are the same, or the first frequency point and the second frequency point are different, the demand level of the second frequency point is not the first level, and the demand level of the first frequency point is higher than or equal to the first frequency point The demand level of the second frequency point, the access network device determines to establish the second slice service at the first frequency point.
一种示例，第一切片业务的第一频点为2.1G，第一需求频点等级为第一等级。第二切片业务的第二频点为2.1G，第二需求频点等级为第一等级。接入网设备对比第一频点与第二频点，确定第一频点与第二频点相同。在该情况下，接入网设备确定在第一频点建立第二切片业务。In an example, the first frequency point of the first slice service is 2.1G, and the first required frequency point level is the first level. The second frequency point of the second slice service is 2.1G, and the second demand frequency point level is the first level. The access network device compares the first frequency point and the second frequency point, and determines that the first frequency point 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.
又一种示例，第一切片业务的第一频点为2.1G，第一需求频点等级为第一等级。第二切片业务的第二频点为3.5G，第二需求频点等级为第二等级。接入网设备对比第一频点与第二频点，确定第一频点与第二频点不同，第二频点需求等级为第二等级(即第二频点需求等级不为第一等级)，且第一频点需求等级高于第二频点需求等级(即第一等级高于第二等级)。在该情况下，接入网设备确定在第一频点建立第二切片业务。In another example, the first frequency of the first slice service is 2.1G, and the first required frequency level is the first level. The second frequency point of the second slice service is 3.5G, and the second demand frequency point level is the second level.
