Abstract
A network selection method, an information sending method, an information obtaining method, and an apparatus. The network selection method includes: receiving disaster condition information related to a first PLMN to which a terminal belongs; and selecting an available PLMN for access in a case that the disaster condition information indicates a disaster condition having occurred on the first PLMN.
Claims17
A network selection method, performed by a terminal and comprising:
- receiving disaster condition information related to a first PLMN to which the terminal belongs;
- and
- selecting an available PLMN for access in a case that the disaster condition information indicates a disaster condition having occurred on the first PLMN;
- wherein the method further comprises:
- obtaining or updating disaster condition network selection information;
- wherein the disaster condition network selection information comprises a PLMN list, and a PLMN in the PLMN list is a PLMN that the terminal is allowed to access in a case that a disaster condition occurs on the first PLMN;
- wherein the obtaining or updating the disaster condition network selection information comprises:
- sending a registration request to a network-side device of the first PLMN;
- wherein the first PLMN is a home PLMN or a visited PLMN;
- and
- receiving registration accept information sent by the network-side device, wherein the registration accept information carries the disaster condition network selection information;
- or,
- wherein the obtaining or updating the disaster condition network selection information comprises:
- receiving a configuration update command sent by a network-side device of the first PLMN, wherein the first PLMN is a home PLMN or a visited PLMN;
- and the configuration update command carries the disaster condition network selection information.
A terminal, comprising a processor, a memory, and a program or instructions stored in the memory and capable of running on the processor, wherein the program or the instructions, when executed by the processor, cause the processor to implement:
- receiving disaster condition information related to a first PLMN to which the terminal belongs;
- and
- selecting an available PLMN for access in a case that the disaster condition information indicates a disaster condition having occurred on the first-PLAN PLMN;
- wherein the program or the instructions, when executed by the processor, further cause the processor to implement:
- obtaining or updating disaster condition network selection information;
- wherein the disaster condition network selection information comprises a PLMN list, and a PLMN in the PLMN list is a PLMN that the terminal is allowed to access in a case that a disaster condition occurs on the first PLMN;
- wherein the obtaining or updating the disaster condition network selection information comprises:
- sending a registration request to a network-side device of the first PLMN;
- wherein the first PLMN is a home PLMN or a visited PLMN;
- and
- receiving registration accept information sent by the network-side device, wherein the registration accept information carries the disaster condition network selection information;
- or,
- wherein the obtaining or updating the disaster condition network selection information comprises:
- receiving a configuration update command sent by a network-side device of the first PLMN, wherein the first PLMN is a home PLMN or a visited PLMN;
- and the configuration update command carries the disaster condition network selection information.
