Abstract

Disclosed in the present application are a cell selection method and device, and a storage medium. The method is applied to a user equipment (UE). The method classifies all LTE cells which the UE has resided, obtains the type information of the LTE cells, and determines residence priority of the LTE cells according to the type information, such that the UE can reside with priority in first-type LTE cells according to the residence priority, thereby ensuring a subsequent reselection or switch from a LTE cell to an SA-supporting first-type 5G cell by means of a cross-mode interoperation process and enhancing the probability of residing in the first-type 5G cell. Since the SA-supporting 5G cell can provide more diversified and improved network services to the UE, the cell selection method can enhance the network service quality for the UE.

具体实施方式detailed description
为了能够更加详尽地了解本发明实施例的特点与技术内容,下面结合附图对本发明实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本发明实施例。In order to understand the features and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
本申请实施例提供了一种小区选择方法,如图1所示,该方法具体可以包括:The embodiment of the present application provides a cell selection method, as shown in FIG. 1 , the method may specifically include:
步骤101:获取驻留过的至少一个长期演进LTE小区的类别信息;Step 101: Obtain category information of at least one long-term evolution LTE cell that has been camped on;
本申请实施例中,LTE小区的类别信息具体用于表征LTE小区其他网络对应的小区的布网方式,主要用于表征与5G网络对应的5G小区的布网方式。具体的,可以根据LTE小区的邻区是否包含5G小区进行分类。In the embodiment of the present application, the category information of the LTE cell is specifically used to characterize the network deployment mode of the cells corresponding to other networks in the LTE cell, and is mainly used to characterize the network deployment mode of the 5G cell corresponding to the 5G network. Specifically, the classification can be performed according to whether the neighboring cells of the LTE cell include 5G cells.
5G NR组网定义了两种方案,分别是独立组网(Standalone,SA)和非独立组网(Non-Standalone,NSA)。因此,5G小区又分为支持SA的第一类5G小区和支持NSA的第二类5G小区,LTE小区的邻区包含第一类5G小区时定义为第一类LTE小区,LTE小区的邻区包含第二类5G小区时定义为第二类LTE小区,邻区即不包含第一类5G小区也不包含第二类5G小区时可以定义为第三类LTE小区。对于第三类LTE小区邻区可以包括其他LTE小区、2G小区、3G小区等。5G NR networking defines two schemes, namely Standalone (SA) and Non-Standalone (NSA). Therefore, 5G cells are further divided into the first type of 5G cells that support SA and the second type of 5G cells that support NSA. When the adjacent cells of LTE cells include the first type of 5G cells, it is defined as the first type of LTE cells, and the adjacent cells of LTE cells are defined as the first type of LTE cells. When the second type of 5G cell is included, it is defined as the second type of LTE cell, and the adjacent cell can be defined as the third type of LTE cell when neither the first type of 5G cell nor the second type of 5G cell is included. For the third type of LTE cell, neighboring cells may include other LTE cells, 2G cells, 3G cells, and the like.
在独立组网中,UE可以通过独立的5G基站接入到5G核心网,能够支持5G的所有应用。如图2所示,第一类LTE基站22和第一类5G基站23关联布网,第一类LTE基站即为第一类LTE小区所对应的基站,第一类5G基站即为第一类5G小区所对应的基站,第一类5G小区为第一类LTE小区的邻区,当UE21初选网时与第一类LTE基站22相连,UE21可以通过跨制式互操作流程从第一类LTE基站22重选或切换到第一类5G基站23,第一类5G基站23为UE21提供5G服务。In the independent networking, the UE can access the 5G core network through an independent 5G base station, which can support all 5G applications. As shown in FIG. 2 , the first type of LTE base station 22 and the first type of 5G base station 23 are associated with network deployment, the first type of LTE base station is the base station corresponding to the first type of LTE cell, and the first type of 5G base station is the first type The base station corresponding to the 5G cell, the first type of 5G cell is the adjacent area of the first type of LTE cell, when UE21 initially selects a network and is connected to the first type of LTE base station 22, UE21 The base station 22 is reselected or switched to the first type of 5G base station 23, and the first type of 5G base station 23 provides 5G services for the UE 21.
在非独立组网中,UE可以工作在双连接模式,双连接模式EUTRA和 NR的ENDC模式。在双连接模式下,UE与非独立组网中的主基站(比如LTE基站)和辅基站(比如支持NSA的5G基站)均进行通信。如图3所示的双连接架构中,第二类LTE基站32和第二类5G基站33关联布网,第二类LTE基站即为第二类LTE小区所对应的基站,第二类5G基站即为第二类5G小区所对应的基站,第二类5G小区为第二类LTE小区的邻区。UE31可以同时与第二类LTE基站32(即主基站)和第二类5G基站33(即辅基站)建立空口连接,从而同时实现与第二类LTE基站32和第二类5G基站33(即辅基站)之间的通信。In non-standalone networking, UE can work in dual-connection mode, dual-connection mode EUTRA and NR's ENDC mode. In the dual-connection mode, the UE communicates with both the primary base station (such as an LTE base station) and a secondary base station (such as a 5G base station supporting NSA) in a non-standalone network. In the dual-connection architecture shown in FIG. 3 , the second type of LTE base station 32 and the second type of 5G base station 33 are associated with network deployment, the second type of LTE base station is the base station corresponding to the second type of LTE cell, and the second type of 5G base station That is, the base station corresponding to the second type of 5G cell, and the second type of 5G cell is a neighboring cell of the second type of LTE cell. The UE31 can establish an air interface connection with the second type of LTE base station 32 (ie the primary base station) and the second type of 5G base station 33 (ie the secondary base station) at the same time, so as to simultaneously realize the connection with the second type of LTE base station 32 and the second type of 5G base station 33 (ie communication between secondary base stations).
具体的,UE在驻留LTE小区后,根据接收到的LTE小区的系统消息自行判断该LTE小区的类别,并保存驻留LTE小区的小区信息和类别信息;或者,UE在驻留LTE小区后,接收LTE基站发送的小区类别信息并保存。Specifically, after the UE camps on the LTE cell, it judges the type of the LTE cell by itself according to the received system information of the LTE cell, and saves the cell information and category information of the LTE cell; or, after the UE camps on the LTE cell , receive and save the cell type information sent by the LTE base station.
步骤102:基于所述至少一个LTE小区的类别信息,确定所述至少一个LTE小区的驻留优先级;Step 102: Determine the camping priority of the at least one LTE cell based on the category information of the at least one LTE cell;
实际应用中,LTE小区的类别包括第一类LTE小区、第二类LTE小区和第三类LTE小区中的至少一种;第一类LTE小区的邻区包括支持独立组网SA的第一类5G小区;所述第二类LTE小区的邻区包括支持非独立组网NSA的第二类5G小区,所述第三类LTE小区的邻区不包括所述第一类5G小区和所述第二类5G小区。In practical applications, the category of the LTE cell includes at least one of the first category of LTE cells, the second category of LTE cells, and the third category of LTE cells; the adjacent cells of the first category of LTE cells include the first category of LTE cells that support independent networking SA. 5G cell; the adjacent area of the second type of LTE cell includes the second type of 5G cell supporting non-independent networking NSA, and the adjacent area of the third type of LTE cell does not include the first type of 5G cell and the first type of 5G cell. Class II 5G cell.
这里,第一类LTE小区的驻留优先级最高,即第一类LTE小区的驻留优先级高于第二类LTE小区和第三类LTE小区的。Here, the camping priority of the first type of LTE cell is the highest, that is, the camping priority of the first type of LTE cell is higher than that of the second type of LTE cell and the third type of LTE cell.
在一些实施例中,第二类LTE小区的驻留优先级高于第三类LTE小区的。随着5G通信技术的发展,5G网络能够为UE提供高速高质量的通信服务,用户对5G网络的使用越来越普遍,在4G通信到5G通信的过渡阶段,5G终端会优先选择从LTE小区重选或切换到5G小区,包括第一类5G小区和第二类5G小区,因此第二类LTE小区的驻留优先级高于第三类LTE小区的,有利于提高UE接入到第二类5G小区的概率。In some embodiments, the camping priority of the second type of LTE cell is higher than that of the third type of LTE cell. With the development of 5G communication technology, 5G networks can provide high-speed and high-quality communication services for UEs, and users' use of 5G networks is becoming more and more common. In the transition stage from 4G communication to 5G communication, 5G terminals will give priority to LTE cells. Reselect or switch to 5G cells, including the first type of 5G cells and the second type of 5G cells. Therefore, the second type of LTE cell has a higher priority than the third type of LTE cell, which is conducive to improving UE access to the second type of LTE cell. The probability of a 5G-like cell.
在一些实施例中,该方法还包括:若所述至少一个LTE小区的类别信息改变时,基于改变后的类别信息调整所述至少一个LTE小区的驻留优先级。In some embodiments, the method further includes: if the category information of the at least one LTE cell changes, adjusting the camping priority of the at least one LTE cell based on the changed category information.
也就是说,若LTE网络和5G网络的网络部属方式改变,导致终端设备驻留过的一个或多个LTE小区的邻区发生变化,进而导致LTE小区类别 发生变化时,通过改变后的LTE小区的类别信息调整这些LTE小区的驻留优先级。比如,LTE小区从第三类LTE小区变为第一类LTE小区时,将该LTE小区的驻留优先级则调整为最高。That is to say, if the network deployment mode of the LTE network and the 5G network is changed, the adjacent cells of one or more LTE cells where the terminal device resides are changed, and the LTE cell category is changed. The category information adjusts the camping priority of these LTE cells. For example, when the LTE cell changes from the third type of LTE cell to the first type of LTE cell, the camping priority of the LTE cell is adjusted to the highest.
步骤103:基于所述至少一个LTE小区的驻留优先级,选择驻留的目标LTE小区。Step 103: Based on the camping priority of the at least one LTE cell, select a camping target LTE cell.
在一些实施例中,基于所述至少一个LTE小区的驻留优先级,选择所述第一类LTE小区作为所述目标LTE小区进行驻留。In some embodiments, the first type of LTE cell is selected as the target LTE cell for camping based on the camping priority of the at least one LTE cell.
实际应用中,若UE驻留过的LTE小区包括第一类LTE小区、第二类LTE小区和第三类LTE小区。驻留优先级为第一类LTE小区>第二类LTE小区>第三类LTE小区,按照该顺序进行选网尝试,优先选择支持第一类5G小区互操作的LTE小区进行驻留,这样后续终端就能从LTE小区重选或者切换到邻区中的第一类5G小区去,从而提高第一类5G小区的驻网概率。In a practical application, if the LTE cells where the UE resides include the first type of LTE cell, the second type of LTE cell and the third type of LTE cell. The priority for camping is the first type of LTE cell > the second type of LTE cell > the third type of LTE cell, and network selection attempts are made in this order, and the LTE cell that supports the first type of 5G cell interoperability is preferentially selected for camping. The terminal can reselect or switch from the LTE cell to the first-type 5G cell in the neighboring cell, thereby improving the network presence probability of the first-type 5G cell.
这里,步骤101至步骤103的执行主体可以为UE的处理器。本申请中描述的用户设备具备移动通信功能的设备,可以包括诸如手机、平板电脑、笔记本电脑、掌上电脑、可穿戴设备、智能手环等。Here, the execution subject of steps 101 to 103 may be the processor of the UE. The user equipment described in this application is a device with a mobile communication function, which may include, for example, a mobile phone, a tablet computer, a notebook computer, a palmtop computer, a wearable device, a smart bracelet, and the like.
采用上述技术方案,通过对驻留过的所有LTE小区进行分类得到LTE小区的类别信息,进一步根据类别信息确定LTE小区的驻留优先级,使UE能够根据驻留优先级优先驻留在第一类LTE小区,从而保证后续能通过跨制式互操作流程从LTE小区重选或者切换到支持SA的第一类5G小区,提高第一类5G小区的驻留概率,由于支持SA的5G小区能够为UE提供更多样更完善的5G网络服务,因此这种小区选择方法能够提高UE的网络服务质量。Using the above technical solution, the category information of the LTE cell is obtained by classifying all the LTE cells that have been camped on, and the camping priority of the LTE cell is further determined according to the category information, so that the UE can preferentially camp on the first cell according to the camping priority. This ensures that the LTE cell can be re-selected or switched to the first type of 5G cell supporting SA through the cross-standard interoperability process, and the probability of staying in the first type of 5G cell is improved. Since the 5G cell supporting SA can be The UE provides more diverse and more complete 5G network services, so this cell selection method can improve the network service quality of the UE.
在本申请上述实施例的基础上,对本申请小区选择方法进行进一步的举例说明,如图4所示,该方法具体包括:On the basis of the above embodiments of the present application, the cell selection method of the present application is further illustrated with an example. As shown in FIG. 4 , the method specifically includes:
步骤401:驻留在所述至少一个LTE小区时,获取所述至少一个LTE小区的系统消息或者RRC连接重配置消息;Step 401: When camping on the at least one LTE cell, obtain a system message or an RRC connection reconfiguration message of the at least one LTE cell;
系统消息是基站周期性发送的下行广播信息。在5G中,UE在开机后读取用于小区附着的系统消息,在无线资源控制(Radio Resource Control,RRC)空闲模式下读取用于小区选择和重选的系统消息,系统消息基本上提供了接入网络所需的所有细节,如系统帧号、系统带宽、公共陆地移动 网(Public Land Mobile Network,PLMN)、小区选择和重选阈值等。System messages are downlink broadcast information periodically sent by the base station. In 5G, the UE reads system messages for cell attachment after power-on, and reads system messages for cell selection and reselection in Radio Resource Control (RRC) idle mode. The system messages basically provide All the details needed to access the network, such as system frame number, system bandwidth, Public Land Mobile Network (PLMN), cell selection and reselection thresholds, etc.
UE在接收到RRC连接重配置消息后,根据RRC连接重配置消息中的配置项,执行对应的操作,比如,RRC连接重配置消息配置了LTE测量事件时,执行对应事件的测量操作。After receiving the RRC connection reconfiguration message, the UE performs corresponding operations according to the configuration items in the RRC connection reconfiguration message. For example, when the RRC connection reconfiguration message configures an LTE measurement event, it performs a measurement operation for the corresponding event.
UE在驻留LTE小区后,能够根据接收到的LTE小区的系统消息或者RRC连接重配置消息判断LTE小区的邻区是否包含5G小区,以及所包含5G小区的类别,从而确定LTE小区类别信息,并保存类别信息用于后续LTE小区驻留操作。After the UE camps on the LTE cell, it can determine whether the neighboring cell of the LTE cell contains a 5G cell and the type of the 5G cell according to the received system message of the LTE cell or the RRC connection reconfiguration message, so as to determine the LTE cell type information. And save the category information for subsequent LTE cell camping operations.
步骤402:基于所述至少一个LTE小区的系统消息或者RRC连接重配置消息,确定所述至少一个LTE小区的类别信息;Step 402: Determine the category information of the at least one LTE cell based on the system message or the RRC connection reconfiguration message of the at least one LTE cell;
在一些实施例中,确定第一类LTE小区的方法具体包括:LTE小区的系统消息中包含指示邻区包括所述第一类5G小区的第一系统信息块时,和/或LTE小区的RRC连接重配置消息中配置了第一类5G小区的B2测量事件时,确定LTE小区为第一类LTE小区。In some embodiments, the method for determining the first type of LTE cell specifically includes: when the system message of the LTE cell includes a first system information block indicating that the neighbor cell includes the first type of 5G cell, and/or the RRC of the LTE cell When the B2 measurement event of the first type of 5G cell is configured in the connection reconfiguration message, the LTE cell is determined to be the first type of LTE cell.
具体的,UE对于驻留的LTE小区,如果系统消息中读到了系统信息块(System Information Blocks,SIB)SIB24,SIB24携带5G邻区的系统消息,那么该LTE小区归为第一类LTE小区。Specifically, for the LTE cell where the UE resides, if the system information reads a system information block (System Information Blocks, SIB) SIB24, and the SIB24 carries the system information of the 5G neighbor cell, then the LTE cell is classified as the first type of LTE cell.
或者,UE对于驻留的LTE小区,如果连接态下配置了第一类5G小区的B2测量事件,那么该LTE小区也归为第一类LTE小区。B2测量事件是指服务小区信号强度低于某个门限值,而邻区信号强度高于某个门限值,B2事件一般情况下用于网络进行跨制式的切换判决,如果配置了对邻区中第一类5G小区的B2测量事件,那么可以认为此LTE小区是存在支持SA的5G邻区的,是支持与SA网络的互操作。Or, for the LTE cell that the UE camps on, if the B2 measurement event of the first type of 5G cell is configured in the connected state, the LTE cell is also classified as the first type of LTE cell. The B2 measurement event means that the signal strength of the serving cell is lower than a certain threshold, but the signal strength of the neighboring cell is higher than a certain threshold. Generally, the B2 event is used for the network to perform cross-standard handover judgment. B2 measurement event of the first type of 5G cell in the area, then it can be considered that this LTE cell has a 5G neighbor cell that supports SA, and supports interoperation with SA network.
在一些实施例中,LTE小区的类别包括第一类LTE小区、第二类LTE小区和第三类LTE小区中的至少一种;第一类LTE小区的邻区包括支持独立组网SA的第一类5G小区;所述第二类LTE小区的邻区包括支持非独立组网NSA的第二类5G小区,所述第三类LTE小区的邻区不包括所述第一类5G小区和所述第二类5G小区。In some embodiments, the category of LTE cells includes at least one of a first category of LTE cells, a second category of LTE cells, and a third category of LTE cells; the neighboring cells of the first category of LTE cells include a first category of LTE cells that support independent networking SA A type of 5G cell; the adjacent area of the second type of LTE cell includes the second type of 5G cell supporting non-independent networking NSA, and the adjacent area of the third type of LTE cell does not include the first type of 5G cell and all The second type of 5G cell is described.
这里,第一类LTE小区的驻留优先级最高,即第一类LTE小区的驻留优先级高于第二类LTE小区和第三类LTE小区的。Here, the camping priority of the first type of LTE cell is the highest, that is, the camping priority of the first type of LTE cell is higher than that of the second type of LTE cell and the third type of LTE cell.
在一些实施例中,第二类LTE小区的驻留优先级高于第三类LTE小区 的。随着5G通信技术的发展,5G网络能够为UE提供高速高质量的通信服务,用户对5G网络的使用越来越普遍,在4G通信到5G通信的过渡阶段,5G终端会优先选择从LTE小区重选或切换到5G小区,包括第一类5G小区和第二类5G小区,因此第二类LTE小区的驻留优先级高于第三类LTE小区的,有利于提高UE接入到第二类5G小区的概率。In some embodiments, the camping priority of the second type of LTE cells is higher than that of the third type of LTE cells. With the development of 5G communication technology, 5G networks can provide high-speed and high-quality communication services for UEs, and users' use of 5G networks is becoming more and more common. In the transition stage from 4G communication to 5G communication, 5G terminals will give priority to LTE cells. Reselect or switch to 5G cells, including the first type of 5G cells and the second type of 5G cells. Therefore, the second type of LTE cell has a higher priority than the third type of LTE cell, which is conducive to improving UE access to the second type of LTE cell. The probability of a 5G-like cell.
在一些实施例中,确定第二类LTE小区的方法具体包括:LTE小区的系统消息中包含指示邻区包括所述第二类5G小区的第二系统信息块时,和/或LTE小区的RRC连接重配置消息中配置了第二类5G小区的B1测量事件时,确定LTE小区为第二类LTE小区;In some embodiments, the method for determining the second type of LTE cell specifically includes: when the system message of the LTE cell includes a second system information block indicating that the neighboring cell includes the second type of 5G cell, and/or the RRC of the LTE cell When the B1 measurement event of the second type of 5G cell is configured in the connection reconfiguration message, the LTE cell is determined to be the second type of LTE cell;
具体的,UE对于驻留的LTE小区,如果系统消息中读到了系统信息块(System Information Blocks,SIB)SIB2,且SIB2中携带有信息元素(Information Element,IE)“upperLayerIndication-r15”,那么该LTE小区归为第二类LTE小区。Specifically, for the LTE cell where the UE resides, if the system information block (System Information Blocks, SIB) SIB2 is read in the system message, and the SIB2 carries the Information Element (Information Element, IE) "upperLayerIndication-r15", then the LTE cells are classified into the second type of LTE cells.
或者,UE对于驻留的LTE小区,如果连接态下配置了对邻区中第二类5G小区的B1测量事件,那么该LTE小区也归为第二类LTE小区。B1测量事件是指邻区信号强度高于某个门限值,网络一般会根据B1测量事件,来判决是否进行NSA的ENDC配置,所以连接态下配置了5G的B1测量事件,可以认为LTE小区支持NSA的ENDC功能,即LTE小区支持与第二类5G小区的双连接模式。Alternatively, for the LTE cell where the UE is camping, if the B1 measurement event for the second type of 5G cell in the neighboring cell is configured in the connected state, the LTE cell is also classified as the second type of LTE cell. The B1 measurement event means that the signal strength of the neighboring cell is higher than a certain threshold. The network generally decides whether to perform the NSA's ENDC configuration according to the B1 measurement event. Therefore, the 5G B1 measurement event is configured in the connected state, and it can be considered that the LTE cell is Supports the NSA's ENDC function, that is, the LTE cell supports the dual-connection mode with the second type of 5G cell.
确定第三类LTE小区的方法具体包括:LTE小区的系统消息中不携带指示邻区包括所述第一类5G小区的第一系统信息块,以及指示邻区包括所述第二类5G小区的第二系统信息块,且LTE小区的RRC连接重配置消息中未配置B1测量事件和B2测量事件时,确定LTE小区为第二类LTE小区。The method for determining the third type of LTE cell specifically includes: the system message of the LTE cell does not carry a first system information block indicating that the neighboring cell includes the first type of 5G cell, and indicates that the neighboring cell includes the second type of 5G cell. When the second system information block is used, and the B1 measurement event and the B2 measurement event are not configured in the RRC connection reconfiguration message of the LTE cell, the LTE cell is determined to be the second type of LTE cell.
也就是LTE网络与SA网络和NSA网络都无关联布网,LTE小区的邻区中即不包含第一类5G小区也不包含第二类5G小区,这类LTE小区定义为第三类LTE小区。对于第三类LTE小区邻区可以包括其他LTE小区、2G小区、3G小区等,UE驻留在第三类LTE小区后可以重选或切换到其他LTE小区、2G小区或3G小区。That is to say, the LTE network is not associated with the SA network and the NSA network. The adjacent area of the LTE cell does not contain either the first type of 5G cell nor the second type of 5G cell. This type of LTE cell is defined as the third type of LTE cell. . For the third type of LTE cell, neighboring cells may include other LTE cells, 2G cells, 3G cells, etc., and the UE may reselection or switch to other LTE cells, 2G cells or 3G cells after camping on the third type of LTE cell.

当系统消息无法判断LTE小区类别,则可以通过在连接态下判断RRC连接重配置消息中是否配置了针对第一类5G小区的B2测量事件,来确定该LTE小区是否为第一类LTE小区。When the system message cannot determine the LTE cell type, it can be determined whether the LTE cell is the first type of LTE cell by judging whether the B2 measurement event for the first type of 5G cell is configured in the RRC connection reconfiguration message in the connected state.
步骤504:LTE小区为第一类LTE小区;Step 504: the LTE cell is the first type of LTE cell;
步骤505:是否配置5G小区的B1测量事件,如果是,执行步骤506;如果否,执行步骤507;Step 505: Whether to configure the B1 measurement event of the 5G cell, if yes, go to Step 506; if not, go to Step 507;
在连接态下判断RRC连接重配置消息中是否配置了针对第二类5G小区的B1测量事件,来确定该LTE小区是否为第二类LTE小区。In the connected state, it is determined whether the B1 measurement event for the second type of 5G cell is configured in the RRC connection reconfiguration message to determine whether the LTE cell is the second type of LTE cell.
步骤506:LTE小区为第二类LTE小区;Step 506: the LTE cell is the second type of LTE cell;
步骤507:系统消息中的SIB2是否存在upperLayerIndication-r15,如果是,执行步骤508;如果否,执行步骤509;Step 507: Whether there is upperLayerIndication-r15 in the SIB2 in the system message, if yes, go to Step 508; if not, go to Step 509;
UE在驻留LTE小区后,还可以通过判断系统消息中的SIB2是存在upperLayerIndication-r15来确定该LTE小区是否为第二类LTE小区。After the UE camps on the LTE cell, it can also determine whether the LTE cell is the second type of LTE cell by judging that the SIB2 in the system message is upperLayerIndication-r15.
步骤508:LTE小区为第二类LTE小区;Step 508: the LTE cell is the second type of LTE cell;
步骤509:LTE小区为第三类LTE小区。Step 509: The LTE cell is a third type of LTE cell.
步骤403:基于所述至少一个LTE小区的类别信息,确定所述至少一个LTE小区的驻留优先级;Step 403: Determine the camping priority of the at least one LTE cell based on the category information of the at least one LTE cell;
这里,所述至少一个LTE小区包括驻留优先级最高的第一类LTE小区,所述第一类LTE小区的邻区包括支持独立组网SA的第一类5G小区。Here, the at least one LTE cell includes a first-type LTE cell with the highest camping priority, and the neighboring cells of the first-type LTE cell include a first-type 5G cell supporting independent networking SA.
实际应用中,若UE驻留过的LTE小区包括第一类LTE小区、第二类LTE小区和第三类LTE小区。驻留优先级为第一类LTE小区>第二类LTE小区>第三类LTE小区。In a practical application, if the LTE cells where the UE resides include the first type of LTE cell, the second type of LTE cell and the third type of LTE cell. The camping priority is the first type of LTE cell > the second type of LTE cell > the third type of LTE cell.
在一些实施例中,该方法还包括:若所述至少一个LTE小区的类别信息改变时,基于改变后的类别信息调整所述至少一个LTE小区的驻留优先级。In some embodiments, the method further includes: if the category information of the at least one LTE cell changes, adjusting the camping priority of the at least one LTE cell based on the changed category information.
步骤404:基于所述至少一个LTE小区的驻留优先级,选择驻留的目标LTE小区。Step 404: Based on the camping priority of the at least one LTE cell, select a camping target LTE cell.
在一些实施例中,基于所述至少一个LTE小区的驻留优先级,选择所述第一类LTE小区作为所述目标LTE小区进行驻留。In some embodiments, the first type of LTE cell is selected as the target LTE cell for camping based on the camping priority of the at least one LTE cell.
实际应用中,按照驻留优先级第一类LTE小区>第二类LTE小区>第三类LTE小区进行选网尝试,优先选择支持第一类5G小区互操作的LTE小区进行驻留,这样后续终端就能从LTE小区重选或者切换到邻区中的第一类5G小区去,从而提高第一类5G小区的驻网概率。In practical applications, network selection is made according to the first type of LTE cell > the second type of LTE cell > the third type of LTE cell, and the LTE cell that supports the first type of 5G cell interoperability is preferentially selected for camping. The terminal can reselect or switch from the LTE cell to the first-type 5G cell in the neighboring cell, thereby improving the network presence probability of the first-type 5G cell.
采用上述技术方案,通过对驻留过的所有LTE小区进行分类得到LTE小区的类别信息,进一步根据类别信息确定LTE小区的驻留优先级,使UE能够根据驻留优先级优先驻留在第一类LTE小区,从而保证后续能通过跨制式互操作流程从LTE小区重选或者切换到支持SA的第一类5G小区,提高第一类5G小区的驻留概率,由于支持SA的5G小区能够为UE提供更多样更完善的5G网络服务,因此这种小区选择方法能够提高UE的网络服务质量。Using the above technical solution, the category information of the LTE cell is obtained by classifying all the LTE cells that have been camped on, and the camping priority of the LTE cell is further determined according to the category information, so that the UE can preferentially camp on the first cell according to the camping priority. This ensures that the LTE cell can be re-selected or switched to the first type of 5G cell supporting SA through the cross-standard interoperability process, and the probability of staying in the first type of 5G cell is improved. Since the 5G cell supporting SA can be The UE provides more diverse and more complete 5G network services, so this cell selection method can improve the network service quality of the UE.
在本申请上述实施例的基础上,对本申请小区选择方法进行进一步的举例说明,如图6所示,该方法具体包括:On the basis of the above embodiments of the present application, the cell selection method of the present application is further illustrated with an example. As shown in FIG. 6 , the method specifically includes:
步骤601:获取驻留过的至少一个长期演进LTE小区的类别信息;Step 601: Obtain category information of at least one long-term evolution LTE cell that has been camped on;
具体的,UE在驻留LTE小区后,根据接收到的LTE小区的系统消息自行判断该LTE小区的类别,并保存驻留LTE小区的小区信息和类别信息;或者,UE在驻留LTE小区后,接收LTE基站发送的小区类别信息并保存。Specifically, after the UE camps on the LTE cell, it judges the type of the LTE cell by itself according to the received system information of the LTE cell, and saves the cell information and category information of the LTE cell; or, after the UE camps on the LTE cell , receive and save the cell type information sent by the LTE base station.
步骤602:基于所述至少一个LTE小区的类别信息,确定所述至少一个LTE小区的驻留优先级;Step 602: Determine the camping priority of the at least one LTE cell based on the category information of the at least one LTE cell;
这里,所述至少一个LTE小区包括驻留优先级最高的第一类LTE小区,所述第一类LTE小区的邻区包括支持独立组网SA的第一类5G小区。所述至少一个LTE小区还包括第二类LTE小区和/或第三类LTE小区;所述第二类LTE小区的邻区包括支持非独立组网NSA的第二类5G小区,所述第三类LTE小区的邻区不包括所述第一类5G小区和所述第二类5G小区。所述第二类LTE小区的驻留优先级高于所述第三类LTE小区的。Here, the at least one LTE cell includes a first-type LTE cell with the highest camping priority, and the neighboring cells of the first-type LTE cell include a first-type 5G cell supporting independent networking SA. The at least one LTE cell further includes a second type of LTE cell and/or a third type of LTE cell; the adjacent cells of the second type of LTE cell include a second type of 5G cell supporting non-standalone networking NSA, and the third type of LTE cell. The neighboring cells of the LTE-like cells do not include the first-type 5G cells and the second-type 5G cells. The camping priority of the second type of LTE cell is higher than that of the third type of LTE cell.
在一些实施例中,该方法还包括:若所述至少一个LTE小区的类别信息改变时,基于改变后的类别信息调整所述至少一个LTE小区的驻留优先 级。In some embodiments, the method further includes: if the category information of the at least one LTE cell changes, adjusting the camping priority of the at least one LTE cell based on the changed category information.
步骤603:基于所述至少一个LTE小区的驻留优先级,选择所述第一类LTE小区作为所述目标LTE小区进行驻留;Step 603: Based on the camping priority of the at least one LTE cell, select the first type of LTE cell as the target LTE cell for camping;
步骤604:若所述目标LTE小区和第一类5G小区的互操作条件满足时,从所述目标LTE小区重选到所述目标LTE小区对应的第一类5G小区,或者从所述目标LTE小区切换到所述目标LTE小区对应的第一类5G小区。Step 604: If the interoperability conditions of the target LTE cell and the first type of 5G cell are satisfied, reselect from the target LTE cell to the first type of 5G cell corresponding to the target LTE cell, or from the target LTE cell to the first type of 5G cell. The cell is switched to the first type of 5G cell corresponding to the target LTE cell.
这里,互操作条件包括小区重选判决条件和小区切换判决条件,UE检测到小区重选判决条件满足时从目标LTE小区重选到第一类5G小区,或者UE检测到小区切换判决条件满足时从目标LTE小区切换到第一类5G小区。例如,小区重选判决条件可以为:UE在空闲态通过检测邻区和当前服务小区的信号强度,当邻区信号强度高于某一门限值,当前服务小区的信号强度低于某一门限值,小区切换判决条件可以为:UE在连接态通过检测邻区和当前服务小区的信号质量,当邻区信号强度高于某一门限值,当前服务小区的信号强度低于某一门限值。Here, the interoperability conditions include the cell reselection decision condition and the cell handover decision condition. When the UE detects that the cell reselection decision condition is satisfied, it reselects from the target LTE cell to the first type of 5G cell, or when the UE detects that the cell handover decision condition is satisfied Handover from the target LTE cell to the first type of 5G cell. For example, the cell reselection decision condition may be: the UE detects the signal strength of the neighboring cell and the current serving cell in the idle state. When the signal strength of the neighboring cell is higher than a certain threshold, the signal strength of the current serving cell is lower than a certain threshold. The cell handover decision condition can be: UE detects the signal quality of the neighboring cell and the current serving cell in the connected state. When the signal strength of the neighboring cell is higher than a certain threshold, the signal strength of the current serving cell is lower than a certain threshold. limit.
在一些实施例中,所述从所述目标LTE小区切换到所述目标LTE小区对应的第一类5G小区,包括:所述用户设备处于连接态时,接收所述目标LTE小区的RRC连接重配置消息;检测到所述RRC连接重配置消息中配置了第二类5G小区的B1测量事件和B2测量事件时,优先处理所述B2测量事件,得到B2事件测量结果;上报所述B2事件测量结果,以使所述用户设备从所述目标LTE小区切换到所述目标LTE小区对应的第一类5G小区。In some embodiments, the handover from the target LTE cell to the first type of 5G cell corresponding to the target LTE cell includes: when the user equipment is in a connected state, receiving an RRC connection reset of the target LTE cell configuration message; when detecting that the B1 measurement event and B2 measurement event of the second type of 5G cell are configured in the RRC connection reconfiguration message, preferentially process the B2 measurement event to obtain a B2 event measurement result; report the B2 event measurement As a result, the user equipment is handed over from the target LTE cell to the first type of 5G cell corresponding to the target LTE cell.
也就是说,当UE驻留在某个LTE小区上,处在连接态时,网络同时配置了5G小区的B1测量事件以及B2测量事件(测量的5G小区可以是相同的,也可以是不同的),那么很可能是该LTE小区即支持5G NSA ENDC功能,也支持SA互操作,这种情况下,UE在测量的时候,优先处理B2事件相关测量与上报,推迟B1事件相关测量与上报,使得UE可以优先上报B2事件测量结果,网络收到B2事件测量结果后,会将UE切换到5G SA网络,从而提高了终端连上5G SA网络的概率。That is to say, when the UE camps on an LTE cell and is in the connected state, the network configures both the B1 measurement event and the B2 measurement event of the 5G cell (the measured 5G cells may be the same or different). ), then it is very likely that the LTE cell supports both the 5G NSA ENDC function and SA interoperability. In this case, when the UE is measuring, it prioritizes the measurement and reporting of the B2 event, and delays the measurement and reporting of the B1 event. This enables the UE to report the B2 event measurement result preferentially. After the network receives the B2 event measurement result, it will switch the UE to the 5G SA network, thereby increasing the probability of the terminal connecting to the 5G SA network.
图7为本申请实施例中小区切换的流程示意图,如图7所示,UE在连接态在LTE网络和SA网络之间进行小区切换操作,小区切换流程具体包括:FIG. 7 is a schematic flowchart of a cell handover in an embodiment of the application. As shown in FIG. 7 , the UE performs a cell handover operation between an LTE network and an SA network in a connected state. The cell handover process specifically includes:
步骤701:UE进行LTE小区搜索驻留并完成网络注册;Step 701: UE performs LTE cell search and camping and completes network registration;
步骤702:UE接收LTE网络下发的RRC Connection Reconfiguration(包含5G小区的B1测量事件和B2测量事件);Step 702: The UE receives the RRC Connection Reconfiguration (including the B1 measurement event and the B2 measurement event of the 5G cell) delivered by the LTE network;
也就是说,LTE小区的邻区即包含第一类5G小区也包含第二类5G小区,且第一类5G小区和第二类5G小区可以为同一个小区或不同小区,同一个小区时表明该5G小区即支持SA模式也支持NSA模式。对于RRC Connection Reconfiguration同时配置了5G小区的B1测量事件和B2测量事件,优先处理B2事件相关测量与上报,推迟B1事件相关测量与上报,使得UE可以优先上报B2事件测量结果,网络收到B2事件测量结果后,会将UE切换到5G SA网络,从而提高了终端连上5G SA网络的概率。That is to say, the neighboring cells of an LTE cell include both the first type of 5G cell and the second type of 5G cell, and the first type of 5G cell and the second type of 5G cell can be the same cell or different cells. The 5G cell supports both SA mode and NSA mode. For RRC Connection Reconfiguration, the B1 measurement event and B2 measurement event of the 5G cell are configured at the same time, the B2 event-related measurement and reporting are preferentially processed, and the B1 event-related measurement and reporting are postponed, so that the UE can report the B2 event measurement result first, and the network receives the B2 event. After the measurement results, the UE will be switched to the 5G SA network, thereby increasing the probability of the terminal connecting to the 5G SA network.
步骤703:UE优先测量5G小区的B2事件,得到B2事件测量结果;Step 703: The UE preferentially measures the B2 event of the 5G cell to obtain a B2 event measurement result;
这里,所测量的5G小区为第一类5小区。Here, the measured 5G cells are the first type 5 cells.
步骤704:UE上报5G小区的B2事件测量结果;Step 704: the UE reports the B2 event measurement result of the 5G cell;
步骤705:LTE网络根据B2事件测量结果,将UE从LTE小区切换到SA网络对应的5G小区。Step 705: The LTE network switches the UE from the LTE cell to the 5G cell corresponding to the SA network according to the B2 event measurement result.
采用上述技术方案,通过对驻留过的所有LTE小区进行分类得到LTE小区的类别信息,进一步根据类别信息确定LTE小区的驻留优先级,使UE能够根据驻留优先级优先驻留在第一类LTE小区,从而保证后续能通过跨制式互操作流程从LTE小区重选或者切换到支持SA的第一类5G小区,提高第一类5G小区的驻留概率,由于支持SA的5G小区能够为UE提供更多样更完善的5G网络服务,因此这种小区选择方法能够提高UE的网络服务质量。Using the above technical solution, the category information of the LTE cell is obtained by classifying all the LTE cells that have been camped on, and the camping priority of the LTE cell is further determined according to the category information, so that the UE can preferentially camp on the first cell according to the camping priority. This ensures that the LTE cell can be re-selected or switched to the first type of 5G cell supporting SA through the cross-standard interoperability process, and the probability of staying in the first type of 5G cell is improved. Since the 5G cell supporting SA can be The UE provides more diverse and more complete 5G network services, so this cell selection method can improve the network service quality of the UE.
