Detailed Description
Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.

Currently, in the 5G protocol, when the terminal device is in a roaming network, the network side device may carry SOR information in a registration accept or a Non-access stratum (NAS) transport message, where the SOR information is used to indicate an updated preferred network list. There are two transmission modes for the SOR information, one is a plaintext mode, and the other is a secure packet (english: secure packet) mode. According to the above protocol, no matter which transmission method is used for the SOR information, the terminal device should use the preferred network list in the most recently received SOR information to select the network. Because the information of the preferred network list of the plaintext transmission mode received after the terminal equipment is powered off is lost, and the received preferred network list of the secure data packet mode is updated into the SIM card and cannot be lost, after the terminal equipment is powered on again, the terminal equipment can use the preferred network list in the SIM card to select the network, but if the SOR information received last time is sent to the terminal equipment in the plaintext mode, the preferred network list used by the terminal equipment is not the latest preferred network list. Therefore, the problem that the terminal device does not use the preferred network list correctly occurs, and the network searching efficiency is possibly influenced, so that the subsequent network access efficiency is reduced.
