Embodiment 1

[0055] based on figure 1 In the illustrated mobile communication system, this embodiment provides a method for selecting a roaming network, which is applicable to the network side device 1, such as figure 2 As shown, the method specifically includes the following steps:

[0056] S11, set the timing duration of the timer.

[0057] S12: Deliver roaming guidance information to the terminal, where the roaming guidance information includes a PLMN list and the timer, so that when the current service is a non-emergency service, the terminal starts the timer and outputs notification information at the same time to It is notified that network handover will be performed after the timer expires, and when no handover rejection instruction in response to the notification information is received, after the timer expires, network selection is performed according to the PLMN list.

[0058] It should be understood that when the terminal is far from the geographic area covered by the home op...

Embodiment 2

[0069] based on figure 1 In the illustrated mobile communication system, this embodiment provides a method for selecting a roaming network, which is suitable for a terminal 2 in a connected state in a roaming place, such as image 3 As shown, the method specifically includes the following steps:

[0070] S21: Receive roaming guidance information delivered by the aforementioned network side device, where the roaming guidance information includes a PLMN list and a timer.

[0071] It should be understood that when the terminal is far from the geographic area covered by the home operator (HPLMN), the HPLMN can find the VPLMN (visited operator) in the area where the terminal is currently located. , Stearing of Roaming) information to guide the terminal to access the VPLMN with the highest priority. The PLMN list includes multiple VPLMNs to be selected and priorities corresponding to each VPLMN.

[0072] In addition to the PLMN list, a timer is added to the roaming guidance infor...

Embodiment 3

[0085] based on figure 1 The mobile communication system shown in this embodiment provides a roaming network selection system, which is suitable for the network side device 1, such as Figure 4 As shown, the system specifically includes the following steps:

[0086] The timer setting module 11 is used to set the timing duration of the timer.

[0087] The roaming guidance information sending module 12 is configured to deliver roaming guidance information to the terminal, where the roaming guidance information includes the PLMN list and the timer, so that the terminal starts the timer when the current service is a non-emergency service , and output notification information at the same time to notify that network handover will be performed after the timer expires. When no handover rejection instruction in response to the notification information is received, after the timer expires, according to the PLMN list for network selection.

[0088] It should be understood that when th...

Abstract

The invention provides a roaming network selection method and system, electronic equipment and a storage medium, which are suitable for a terminal in a connected state in a roaming place, and the method comprises the following steps: setting the timing duration of a timer; and issuing roaming guidance information to a terminal, the roaming guidance information including a PLMN list and the timer, so that the terminal starts the timer when the current service is a non-emergency service, and outputs notification information at the same time to notify that network switching is to be performed after the timer expires. And when a switching rejection instruction responding to the notification information is not received, after the timer expires, performing network selection according to the PLMN list. According to the invention, the UE in the connection state at the roaming place can access the VPLMN with higher priority, and the running high-priority service is not influenced.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a roaming network selection method, system, electronic device and storage medium. Background technique [0002] The mobile communication system provides the roaming capability of the user, and the user can communicate in different places and different cells of the cellular network. In a roaming scenario, the UE (user equipment) usually only performs automatic PLMN (operator) selection in an idle state to select an operator according to priority. When the UE is in the connected state, there is often a service running in the UE, such as talking or surfing the Internet. At this time, PLMN reselection is generally not performed, because it may cause service interruption and affect user experience. [0003] In this regard, some operators have proposed that they can guide the UE to a higher priority VPLMN (visited operator) in the UE connected state, but cannot a...
