一种指定漫回的方法、漫回的方法、网络设备及终端A method for specifying rambling, a rambling method, a network device and a terminal

技术领域technical field

本发明涉及通信技术领域，特别是指一种指定漫回的方法、漫回的方法、网络设备及终端。The present invention relates to the technical field of communications, and in particular, to a method for specifying a floodback, a method for floodback, a network device and a terminal.

背景技术Background technique

运营商在本网无线信号没有覆盖到的区域，可通过其他运营商的移动通信网络提供移动通信服务，以实现运营商网络覆盖的自然延伸，有如下两种方式：Operators can provide mobile communication services through the mobile communication networks of other operators in areas not covered by the wireless signal of this network, so as to realize the natural extension of the operator's network coverage. There are two ways as follows:

(1)网络共享方式，典型的方案是接入网共享方案(RAN Sharing)：多个运营商通过共享基站接入各自用户的终端，并由各自运营商的核心网完成业务处理。该方式对网络改动较大，共享基站需要连接多个运营商的核心网，小区需要广播多个运营商的PLMN ID等。(1) Network sharing mode, a typical solution is access network sharing solution (RAN Sharing): multiple operators access the terminals of their respective users through shared base stations, and the core networks of their respective operators complete service processing. This method greatly changes the network. The shared base station needs to be connected to the core networks of multiple operators, and the cell needs to broadcast the PLMN IDs of multiple operators.

(2)异网漫游方式，典型的方案是国际漫游方案和国内异网漫游方案(Roaming)：当本网无信号，他网有信号时，进行漫出；当漫出用户搜索到本网信号时漫回本网。该方式对网络改动较小，只需要双方核心网进行过用户面对接。(2) Inter-network roaming mode, typical schemes are international roaming scheme and domestic inter-net roaming scheme (Roaming): when there is no signal on this network and there is a signal on other networks, the roaming is performed; when the roaming user searches for the signal of the local network Time to return to this website. In this method, the network changes are small, and only the core networks of both parties need to be connected to the user plane.

异网漫游方式对运营商网络改动较小，应用范围较广。对于传统的异网漫游方式，离开归属运营商覆盖后，终端通过脱网重搜方式驻留漫游运营商实现漫出，之后按终端/USIM卡存储的搜索高优先级PLMN定时器，周期性搜索归属运营商PLMN(Home PLMN，简称HPLMN)，搜索到后返回归属运营商。The inter-network roaming method makes little changes to the operator's network and has a wide range of applications. For the traditional inter-network roaming mode, after leaving the coverage of the home operator, the terminal stays on the roaming operator by off-network re-search to realize the roaming out, and then searches the high-priority PLMN timer stored in the terminal/USIM card to periodically search The home operator PLMN (Home PLMN, HPLMN for short) is searched and returned to the home operator.

2、异网漫游的新应用2. New application of inter-network roaming

目前异网漫游存在新的应用场景，即国内以扩容为目标的同覆盖漫游场景。因为5G业务需求逐步增大，部分运营商频谱不足导致容量受限，需要借用其他运营商的频谱以扩充容量。该场景下归属运营商和漫游运营商均有信号，只是使用不同的频段，这与本网无信号、他网有信号的传统漫游方式不同。At present, there is a new application scenario for inter-network roaming, that is, the domestic same-coverage roaming scenario aiming at capacity expansion. Because the demand for 5G services is gradually increasing, some operators have insufficient spectrum, resulting in limited capacity. It is necessary to borrow the spectrum of other operators to expand capacity. In this scenario, both the home operator and the roaming operator have signals, but use different frequency bands, which is different from the traditional roaming method in which there is no signal in the local network and signals in other networks.

针对新的异网漫游场景，终端的漫出采用了重定向的新方案，即归属运营商释放RRC连接时指定漫游运营商的频点为终端搜索的频点，终端直接去该频点驻留漫游运营商网络，重定向时延比脱网重搜时延大幅度缩短，用户体验相比脱网重搜更好。为了避免对漫游运营商网络进行改造，终端的漫回仍为传统的漫游方式，终端在漫游网络下按照终端/USIM卡存储的搜索HPLMN定时器周期搜索漫回。For the new inter-network roaming scenario, a new redirection scheme is adopted for terminal roaming, that is, when the home operator releases the RRC connection, the frequency point of the roaming operator is designated as the frequency point searched by the terminal, and the terminal directly goes to the frequency point to camp on. When roaming the carrier's network, the redirection delay is significantly shorter than the offline re-search delay, and the user experience is better than the offline and re-search. In order to avoid the transformation of the roaming operator's network, the terminal's roaming mode is still the traditional roaming mode, and the terminal searches for the roaming back according to the period of the search HPLMN timer stored in the terminal/USIM card under the roaming network.

在如上提到的，对于以扩容为目标的同覆盖漫游场景，终端的漫回仍为传统的漫游方式，按照终端/USIM卡存储的搜索HPLMN定时器周期搜索漫回，存在如下问题：As mentioned above, for the same-coverage roaming scenario aiming at capacity expansion, the terminal's roaming mode is still the traditional roaming method, and the roaming is searched periodically according to the search HPLMN timer stored in the terminal/USIM card, and the following problems exist:

1、该定时器取值较长，因为在出国漫游下，归属运营商没有信号，如果使用较短的定时器周期搜索归属运营商信号，每次都搜不到，会导致终端耗电大幅增加，待机时长变短。1. The value of this timer is long, because when roaming abroad, the home operator has no signal. If a short timer period is used to search for the signal of the home operator, the signal of the home operator cannot be found every time, which will greatly increase the power consumption of the terminal. , the standby time is shortened.

2、该定时器取值属于固化方案，一次生效。若要修改的话，需要对发售的市场上终端进行OTA升级，升级存在较大难度，不够灵活，不容易快速修改定时器取值。2. The value of this timer belongs to the curing scheme and takes effect once. If you want to modify it, you need to perform an OTA upgrade on the terminal on the market. The upgrade is difficult, not flexible enough, and it is not easy to quickly modify the timer value.

该实施例中，网络指定返回方法与传统的按终端/USIM卡存储定时器返回方法的关系：网络下发的定时器优先级最高，终端优先按照该定时器搜索HPLMN尝试返回。如果网络没有下发，则终端仍按终端/USIM卡存储的搜索高优先级PLMN定时器搜索HPLMN尝试返回。In this embodiment, the relationship between the network-specified return method and the traditional return method based on the terminal/USIM card storage timer: the timer delivered by the network has the highest priority, and the terminal preferentially searches for HPLMN according to the timer and tries to return. If the network does not deliver, the terminal still searches for HPLMN according to the search high-priority PLMN timer stored in the terminal/USIM card and tries to return.

归属网络源小区可以下发漫回的PLMN。The source cell of the home network can deliver the PLMN that is flooded back.
