All other embodiments obtained under the premise of creative work belong to the scope of protection of this application.
在以下的描述中,涉及到“一些实施例”,其描述了所有可能实施例的子集,但是可以理解,“一些实施例”可以是所有可能实施例的相同子集或不同子集,并且本申请实施例所记载的技术方案之间,可以在不冲突的情况下相互结合。In the following description, references to "some embodiments" describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or a different subset of all possible embodiments, and The technical solutions described in the embodiments of the present application may be combined without conflict.
在对本申请实施例的技术方案进行介绍之前,下面先对相关技术进行说明。Before introducing the technical solutions of the embodiments of the present application, the related technologies will be described below.
目前,在无线通信领域中,5G网络建网初期采用NSA方案,具体地,可由4G独立部署控制面(4G承载控制信令),5G和4G共同部署用户面(5G和4G均承载用户面数据),或者5G独立部署用户面(仅5G承载用户面数据)。然而,实际应用中,并不是所有的LTE小区都是NSA小区,当NSA终端接入到非NSA的LTE小区时,NSA终端只享受到LTE单侧的用户体验,而无法体验到5G网络的优势,因此,非NSA的LTE小区需要实现定向切换,才能享用到5G网络所带来的大容量的用户体验。At present, in the field of wireless communication, the NSA solution is adopted in the initial stage of 5G network construction. Specifically, the control plane can be deployed independently by 4G (4G carries control signaling), and the user plane can be deployed jointly by 5G and 4G (both 5G and 4G carry user plane data). ), or 5G independently deploys the user plane (only 5G bears user plane data). However, in practical applications, not all LTE cells are NSA cells. When an NSA terminal accesses a non-NSA LTE cell, the NSA terminal only enjoys the user experience of LTE on one side, but cannot experience the advantages of the 5G network. Therefore, non-NSA LTE cells need to implement directional handover in order to enjoy the high-capacity user experience brought by the 5G network.
在相关技术中,5G NSA的公网启用默认的定向切换功能,在5G NSA覆盖区域内,当终端驻留在非锚点LTE小区时,在进行定向切换过程中,对于所有的业务均可通过周期性测量网络中锚点LTE小区的信号质量,进行由非锚点LTE到锚点LTE的定向切换,以保证终端尽可能驻留在5G。需要说明的是,这里所涉及的公网,特指普通商用网络,比如城区或者农村的商用网络。In related technologies, the public network of 5G NSA enables the default directional handover function. In the coverage area of 5G NSA, when the terminal resides in a non-anchor LTE cell, during the directional handover process, all services can pass Periodically measure the signal quality of the anchor LTE cell in the network, and perform directional handover from non-anchor LTE to anchor LTE to ensure that the terminal resides in 5G as much as possible. It should be noted that the public network involved here specifically refers to ordinary commercial networks, such as urban or rural commercial networks.
相关技术中,5G NSA的公网所采用的定向切换决策并不区分业务类型,一般来说,为了保证终端尽可能驻留在5G,定向切换到锚点LTE的信号质量门限一般设置较低,这样,若采用相关技术中的定向切换决策,则会出现切换后的锚点LTE信号质量差于切换前的非锚点LTE信号质量的情况。In related technologies, the directional handover decision adopted by the 5G NSA public network does not distinguish between service types. Generally speaking, in order to ensure that the terminal stays on 5G as much as possible, the signal quality threshold for directional handover to anchor LTE is generally set lower. In this way, if the directional handover decision in the related art is adopted, the signal quality of the anchor LTE signal after the handover is worse than that of the non-anchor LTE signal before the handover.
为了避免出现上述情况,相关技术中在进行定向切换决策时,对于数据业务,终端由非锚点LTE定向切换到锚点LTE时,即使切换后的锚点LTE信号质量差于切换前的非锚点LTE信号质量,终端仍可以通过添加新空口(NR,New Radio)辅节点来提升数据传输速率。对于语音业务,由于采用的是长期演进语音承载(VOLTE,Voice Over Long-Term Evolution)策略,则终端在LTE侧实现语音业务,此时,终端由非锚点LTE定向切换到锚点LTE时,语音业务仍在LTE侧完成,而NR辅节点不会传输语音业务数据。同时,在移动性场景下,如果终端在同时有锚点LTE和非锚点LTE的覆盖场景下,优先切换到非锚点LTE,那么可以说明非锚点LTE覆盖优于锚点LTE,在此场景下发生定向切换,将会导致语音质量变差,同时增加语音业务中断时延。In order to avoid the above situation, when making directional handover decisions in the related art, for data services, when the terminal switches from non-anchor LTE to anchor LTE, even if the signal quality of the anchor LTE after handover is worse than that of the non-anchor LTE before handover In terms of LTE signal quality, the terminal can still increase the data transmission rate by adding a new air interface (NR, New Radio) secondary node. For the voice service, since the VOLTE (Voice Over Long-Term Evolution) strategy is adopted, the terminal implements the voice service on the LTE side. At this time, when the terminal switches from the non-anchor LTE to the anchor LTE, The voice service is still completed on the LTE side, and the NR secondary node will not transmit voice service data. At the same time, in the mobility scenario, if the terminal preferentially switches to non-anchor LTE in the coverage scenario of both anchor LTE and non-anchor LTE, then it can be explained that the coverage of non-anchor LTE is better than that of anchor LTE. Directional handover in the scenario will result in poor voice quality and increase voice service interruption delay.
然而,对于相关技术中的定向切换决策导致的增加语音业务中断时延,降低语音质量的问题,目前尚未有有效解决方案。However, there is currently no effective solution to the problems of increased voice service interruption delay and reduced voice quality caused by the directional handover decision in the related art.
基于此,在本申请的各种实施例中,第一网络设备确定终端当前运行业务的业务类型,所述当前运行业务的业务类型包括数据业务和语音业务中之一;基于所述当前运行业务的业务类型,确定对应的小区定向切换决策;不同的业务类型对应不同的小区定向切换决策;所述语音业务对应的小区定向切换决策,与所述语音业务对应的语音质量关联。Based on this, in various embodiments of the present application, the first network device determines the service type of the service currently running on the terminal, and the service type of the currently running service includes one of a data service and a voice service; based on the currently running service According to the service type, determine the corresponding cell-directed handover decision; different service types correspond to different cell-directed handover decisions; the cell-directed handover decision corresponding to the voice service is associated with the voice quality corresponding to the voice service.
采用本申请实施例的方案,通过区分终端当前运行业务的业务类型,对于不同的业务类型采用不同的小区定向切换决策,在语音业务场景下可基于语音业务对应的语音质量进行定向切换决策,如此,能够有效降低相关技术中定向切换导致的语音业务中断时延,提升语音质量,进而提升用户体验。Using the solution of the embodiment of the present application, by distinguishing the service type of the terminal's current service, different cell directional handover decisions are adopted for different service types, and in the voice service scenario, the directional handover decision can be made based on the voice quality corresponding to the voice service, so , which can effectively reduce the voice service interruption delay caused by directional handover in related technologies, improve voice quality, and further improve user experience.
下面结合附图及实施例对本申请方案再作进一步详细的描述。The scheme of the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments.
本申请实施例提供了一种切换决策的确定方法,该方法应用于第一网络设备,图1为本申请实施例提供的一种切换决策的确定方法的流程示意图,如图1所示,该方法包括:An embodiment of the present application provides a method for determining a handover decision, and the method is applied to a first network device. FIG. 1 is a schematic flowchart of a method for determining a handover decision provided in an embodiment of the present application. As shown in FIG. 1 , the Methods include:
步骤101,第一网络设备确定终端当前运行业务的业务类型;所述当前运行业务的业务类型包括数据业务和语音业务中之一。
步骤102,基于所述当前运行业务的业务类型,确定对应的小区定向切换决策;不同的业务类型对应不同的小区定向切换决策。
这里,所述语音业务对应的小区定向切换决策,与所述语音业务对应的语音质量关联;所述小区定向切换决策用于供所述终端进行小区定向切换,且切换后的目标小区支持NSA功能。Here, the cell-directed handover decision corresponding to the voice service is associated with the voice quality corresponding to the voice service; the cell-directed handover decision is used for the terminal to perform cell-directed handover, and the target cell after handover supports the NSA function .
实际应用中,实施本申请实施例的第一网络设备可以是接入网设备,比如基站等。In practical applications, the first network device implementing the embodiment of the present application may be an access network device, such as a base station.
在本申请实施例中,小区定向切换,可以理解为终端在无线接入网的控制下,实现从源小区到目标小区的无线链路连接的迁移,以保证无缝的移动通信服务,这里的目标小区需支持NSA功能。也就是说,终端进行小区定向切换后将接入到支持NSA的LTE小区,亦即定向切换是指终端最终切换到支持NSA功能的目标小区。In this embodiment of the present application, the cell-directed handover can be understood as the migration of the terminal's wireless link connection from the source cell to the target cell under the control of the radio access network, so as to ensure seamless mobile communication services. Here, The target cell needs to support the NSA function. That is to say, the terminal will access the LTE cell supporting the NSA after the cell directional handover, that is, the directional handover means that the terminal finally switches to the target cell supporting the NSA function.
相关技术中5G NSA的公网所采用的定向切换决策并不区分业务类型,而是对所有的业务类型采用统一的定向切换决策进行定向切换,那么,对于语音业务来说,可能存在语音业务中断、语音质量变差的情况,进而影响用户体验。In related technologies, the directional handover decision adopted by the public network of 5G NSA does not distinguish between service types, but uses a unified directional handover decision for all service types to perform directional handover. Then, for voice services, there may be voice service interruptions , The voice quality deteriorates, which in turn affects the user experience.
基于此,实际应用时,第一网络设备先区分终端当前运行业务的业务类型,即区分终端当前运行业务的业务类型是数据业务,还是语音业务,进而对于语音业务,基于语音质量进行定向切换决策,从而能够有效降低相关技术中定向切换导致的语音业务中断时延,提升语音质量。Based on this, in actual application, the first network device first distinguishes the service type of the terminal's current service, that is, distinguishes whether the service type of the terminal's current service is a data service or a voice service, and then for the voice service, a directional switching decision is made based on the voice quality , so as to effectively reduce the voice service interruption delay caused by the directional handover in the related art, and improve the voice quality.
在一些实施例中,第一网络设备可通过如下方式确定终端当前运行业务的业务类型:In some embodiments, the first network device may determine the service type of the service currently running on the terminal in the following manner:
获取所述终端当前运行业务的QCI;Obtain the QCI of the service currently running on the terminal;
基于获取的QCI,确定所述终端当前运行业务的业务类型。Based on the acquired QCI, determine the service type of the service currently running on the terminal.
具体来说,当终端驻留在非锚点LTE小区,在非锚点LTE小区覆盖范围内进行业务处理时,第一网络设备可直接获取终端当前运行业务的QCI,QCI是用于标识业务数据包传输特性的参数,通常来说,不同的承载业务对应一个QCI值。实际应用时,基于获取的QCI,以及QCI与承载业务的业务类型的对应关系,可以确定终端当前运行业务的业务类型;其中,所述当前运行业务的业务类型包括数据业务和语音业务中之一。Specifically, when the terminal resides in a non-anchor LTE cell and performs service processing within the coverage of the non-anchor LTE cell, the first network device can directly obtain the QCI of the service currently running on the terminal. The QCI is used to identify service data Parameters of packet transmission characteristics. Generally speaking, different bearer services correspond to a QCI value. In actual application, based on the obtained QCI and the corresponding relationship between the QCI and the service type of the bearer service, the service type of the service currently running on the terminal can be determined; wherein, the service type of the currently running service includes one of a data service and a voice service .
这里,可将QCI与承载业务的业务类型的对应关系存储在一个映射表中,通过查询该映射表可基于获取的QCI,确定终端当前运行业务的业务类型。Here, the corresponding relationship between the QCI and the service type of the bearer service may be stored in a mapping table, and the service type of the service currently running by the terminal may be determined based on the acquired QCI by querying the mapping table.
举例来说,若第一网络设备获取到的终端当前运行业务的QCI的值为5,即获取到QCI5,可通过查询映射表确定终端当前运行业务的业务类型为语音业务;若第一网络设备获取到QCI8,可通过查询映射表确定终端当前运行业务的业务类型为数据业务。For example, if the value of the QCI of the terminal's current operating service obtained by the first network device is 5, that is, QCI5 is obtained, and the service type of the terminal's current operating service can be determined to be a voice service by querying the mapping table; if the first network device After obtaining the QCI8, it can be determined by querying the mapping table that the service type of the service currently running on the terminal is a data service.
在一些实施例中,第一网络设备基于所述当前运行业务的业务类型,确定对应的小区定向切换决策,包括以下之一:In some embodiments, the first network device determines a corresponding cell-directed handover decision based on the service type of the currently running service, including one of the following:
在所述当前运行业务的业务类型为数据业务的情况下,基于锚点优先级确定所述数据业务对应的小区定向切换决策;In the case where the service type of the currently running service is a data service, determine a cell-directed handover decision corresponding to the data service based on the priority of the anchor point;
在所述当前运行业务的业务类型为语音业务的情况下,基于所述语音业务对应的语音质量,确定所述语音业务对应的小区定向切换决策。If the service type of the currently running service is a voice service, based on the voice quality corresponding to the voice service, determine a cell-directed handover decision corresponding to the voice service.
实际应用时,当确定的终端当前运行业务的业务类型为数据业务时,可采用相关技术中5G NSA公网启用的定向切换决策,即基于锚点优先级确定数据业务对应的小区定向切换决策,以便终端尽可能驻留在5G。这里的锚点优先级包括锚点LTE相比非锚点LTE具有更高优先级,也就是说,当终端驻留在非锚点LTE时,对于数据业务,直接切换到锚点LTE,以保证终端尽可能驻留在5G,使得终端在进行小区定向切换后能够享用5G带来的大容量的用户体验。但是,当第一网络设备确定终端当前运行业务的业务类型为语音业务,例如VOLTE语音业务时,终端并不直接切换到锚点LTE,而是基于语音业务对应的语音质量,确定语音业务对应的小区定向切换决策。In practical application, when the service type of the determined terminal's current service is data service, the directional handover decision enabled by the 5G NSA public network in the related technology can be adopted, that is, the directional handover decision of the cell corresponding to the data service is determined based on the priority of the anchor point, So that the terminal resides on 5G as much as possible. The anchor point priority here includes that the anchor point LTE has higher priority than the non-anchor point LTE, that is, when the terminal camps on the non-anchor point LTE, for the data service, it is directly handed over to the anchor point LTE to ensure The terminal stays on 5G as much as possible, so that the terminal can enjoy the large-capacity user experience brought by 5G after cell-directed handover. However, when the first network device determines that the service type of the terminal's current service is a voice service, such as a VOLTE voice service, the terminal does not directly switch to the anchor point LTE, but determines the voice service corresponding to the voice service based on the voice quality corresponding to the voice service. Cell-directed handover decision.
基于此,在一些实施例中,第一网络设备可通过如下方式基于所述语音业务对应的语音质量,确定所述语音业务对应的小区定向切换决策:Based on this, in some embodiments, the first network device may determine the cell-directed handover decision corresponding to the voice service based on the voice quality corresponding to the voice service in the following manner:

In actual application, the values of the start-up measurement threshold and the handover threshold can be specially set according to the actual situation of the voice quality corresponding to the voice service, so as to ensure the quality of the voice service.

这里,所述测量控制消息的发送与所述启动测量门限关联,也就是说,由启动测量门限来判定是否向终端发送测量控制消息。Here, the sending of the measurement control message is associated with the start measurement threshold, that is, whether to send the measurement control message to the terminal is determined by the start measurement threshold.
基于此,在一些实施例中,第一网络设备向所述终端发送测量控制消息,包括:Based on this, in some embodiments, the first network device sends a measurement control message to the terminal, including:

For example, the first network device may be a first base station, and the non-anchor LTE cell communicates with the first network device. within the coverage of the first base station. Adjacent cells of the currently accessed cell may include non-anchor LTE cells and anchor LTE cells, and the adjacent cells of the currently accessed cell communicate with the second network device, for example, the second network device may be a second base station , the neighboring cell of the currently accessed cell is within the coverage of the second base station.
这里,第一网络设备向终端发送测量控制消息,以触发终端对当前接入的小区的相邻小区信号质量进行测量。Here, the first network device sends a measurement control message to the terminal to trigger the terminal to measure the signal quality of the neighboring cell of the currently accessed cell.
需要说明的是,当第一网络设备将终端当前接入的小区信号质量与所述启动测量门限进行比较得到的第一比较结果,表征当前接入的小区信号质量高于或等于所述启动测量门限的情况下,第一网络设备未向所述终端发送所述测量控制消息,此时不需要触发终端对当前接入的小区的相邻小区信号质量进行测量。It should be noted that when the first network device compares the signal quality of the cell currently accessed by the terminal with the start measurement threshold, the first comparison result indicates that the signal quality of the cell currently accessed is higher than or equal to the start measurement threshold. In the case of the threshold, the first network device does not send the measurement control message to the terminal, and at this time, the terminal does not need to be triggered to measure the signal quality of the neighboring cell of the currently accessed cell.
实际应用时,第一网络设备向所述终端发送测量控制消息,可通过如下方式实现:In actual application, the first network device sends a measurement control message to the terminal, which may be implemented in the following manner:

需要说明的是,终端在进行语音业务时,基于语音质量的切换的优先级高于基于锚点优先级的切换。It should be noted that when the terminal is performing a voice service, the priority of the handover based on the voice quality is higher than the handover based on the anchor priority.
