本申请实施例涉及通信领域，具体涉及一种网络选择的方法、终端设备和网络设备。The embodiment of the present application relates to the communication field, and in particular to a method for network selection, a terminal device, and a network device.
在新无线(New Radio，NR)系统中，终端的非接入层(Non-Access Stratum，NAS)基于公共陆地移动网络(Public Land Mobile Network，PLMN)的优先级排序进行网络选择(即PLMN选择)。PLMN的优先级排序为注册的PLMN(Registered PLMN，RPLMN)高于归属PLMN(Home PLMN，HPLMN)或第一等价归属PLMN(the first EHPLMN)。In the New Radio (NR) system, the non-access stratum (Non-Access Stratum, NAS) of the terminal performs network selection based on the priority ranking of the Public Land Mobile Network (PLMN) (that is, the PLMN selection ). The priority of the PLMN is that the registered PLMN (Registered PLMN, RPLMN) is higher than the home PLMN (Home PLMN, HPLMN) or the first equivalent home PLMN (the first EHPLMN).
但是，对于网络状态不稳定的终端(比如漫游的终端)，采用上述网络选择机制会使得终端驻留到RPLMN或定期返回到RPLMN，导致终端的数据传输不稳定问题，因此，如何实现高质量的网络选择是一项急需解决的问题。However, for a terminal with an unstable network state (such as a roaming terminal), the use of the above network selection mechanism will cause the terminal to reside in the RPLMN or return to the RPLMN periodically, resulting in unstable data transmission of the terminal. Therefore, how to achieve high-quality Network selection is an urgent problem.

为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific examples. The following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the protection scope of the embodiments of the present application. The embodiment of the present application includes at least part of the following content.
为了满足垂直行业对延迟、移动性、可靠性、位置精度等方面的需求，5G系统需要对如何在接入网支持垂直业务进行增强。一种可能的场景就是支持物联网(Internet of Things，IOT)业务的传输。IoT业务的传输特性通常有以下几点：In order to meet the requirements of vertical industries on delay, mobility, reliability, and location accuracy, 5G systems need to enhance how to support vertical services on the access network. One possible scenario is to support transmission of Internet of Things (Internet of Things, IOT) services. The transmission characteristics of IoT services usually have the following points:
1、IoT业务是静止的。1. The IoT business is static.
2、IoT业务可以位于覆盖范围有限的偏远位置。2. IoT services can be located in remote locations with limited coverage.
3、IoT业务需要稳定的数据连接，作为测量和控制网络的一部分。3. IoT services require stable data connections as part of the measurement and control network.
4、IoT设备可能是永久漫游的，比如IoT设备的模块安装在国外，或者，有意使得在任何情况下都能使得为用户提供最佳覆盖。4. The IoT device may be permanently roaming, for example, the module of the IoT device is installed abroad, or it is intentional to provide users with the best coverage under any circumstances.
在UE进入系统覆盖区域时，UE执行小区搜索过程。无论UE处于哪种状态(例如连接态(connected)，空闲态(idle)，非激活态(inactive))，UE在系统中移动时都将进行小区搜索，以实现移动性。When the UE enters the coverage area of the system, the UE performs a cell search procedure. No matter which state the UE is in (for example, connected state (connected), idle state (idle), inactive state (inactive)), the UE will perform cell search when moving in the system to achieve mobility.
在相关技术中，UE的非接入层(Non-Access Stratum，NAS)基于PLMN的优先级排序进行网络选择(即PLMN选择)，一般来说，PLMN的优先级排序为注册的PLMN(Registered PLMN，RPLMN)高于归属PLMN(Home PLMN，HPLMN)或第一等价归属PLMN(the first EHPLMN)。In related technologies, the UE's Non-Access Stratum (Non-Access Stratum, NAS) performs network selection based on PLMN priority ranking (ie, PLMN selection). Generally speaking, the PLMN priority ranking is Registered PLMN (Registered PLMN , RPLMN) is higher than the home PLMN (Home PLMN, HPLMN) or the first equivalent home PLMN (the first EHPLMN).
在一些场景中，对于网络状态不稳定的UE(比如漫游的UE)，上述网络选择方式存在一些问题。这是由于当前的网络选择机制/漫游转向机制使得即使存在其他条件更好(如信道质量条件更优)的网络可用，UE也需要根据PLMN优先级进行网络选择，使得UE优先选择停留在RPLMN网络或需要定期返回到RPLMN网络，导致UE的连接质量差，最终导致UE传输不稳定等问题，因此，如何实现高质量的网络选择是一项急需解决的问题。In some scenarios, for a UE with an unstable network state (such as a roaming UE), there are some problems in the above network selection method. This is because the current network selection mechanism/roaming steering mechanism makes it necessary for the UE to select a network based on the PLMN priority even if there are other networks with better conditions (such as better channel quality conditions) available, so that the UE prefers to stay on the RPLMN network Or it needs to return to the RPLMN network periodically, resulting in poor connection quality of the UE, and finally causing problems such as unstable transmission of the UE. Therefore, how to realize high-quality network selection is an urgent problem to be solved.

方式3：终端设备的NAS同时考虑PLMN的信道质量和PLMN的优先级进行PLMN选择。Mode 3: The NAS of the terminal device selects a PLMN by considering both the channel quality of the PLMN and the priority of the PLMN.
例如，若搜索到的PLMN中优先级最高的PLMN的信道质量为X1，对应的调整量为delt1，则目标信道质量为X1+delta1，优先级次高的PLMN的信道质量为X2，对应的调整量为delta2，则目标信道质量为X2+delta2，若X1+delta1大于X2+delta2，则可以选择优先级最高的PLMN作为目标PLMN，否则选择优先级次高的PLMN作为目标PLMN。步骤4：终端设备的AS获取终端设备的NAS选择的目标PLMN，进一步进行小区的选择或驻留等。For example, if the channel quality of the PLMN with the highest priority among the searched PLMNs is X1, and the corresponding adjustment amount is delt1, then the target channel quality is X1+delta1, and the channel quality of the PLMN with the second highest priority is X2, and the corresponding adjustment If the quantity is delta2, the target channel quality is X2+delta2. If X1+delta1 is greater than X2+delta2, the PLMN with the highest priority can be selected as the target PLMN, otherwise, the PLMN with the second highest priority can be selected as the target PLMN. Step 4: The AS of the terminal device obtains the target PLMN selected by the NAS of the terminal device, and further selects or resides in a cell.
综上，对于特定终端，或者特定业务，终端设备基于PLMN优先级排序和PLMN的信道质量信息进行PLMN选择，相当于考虑了终端设备的设备部署情况，位置、信道质量等信息，有利于终端设备选择到合适的PLMN，进而保证业务的连续传输。In summary, for a specific terminal or a specific service, the terminal device selects the PLMN based on the PLMN priority ranking and the channel quality information of the PLMN, which is equivalent to considering the device deployment, location, channel quality and other information of the terminal device, which is beneficial to the terminal device.
