Abstract
A paging method, includes: in response to determining that user equipment (UE) to which a Subscriber Identification Module (SIM) card to be paged belongs is multi-SIM user equipment and multiple SIM cards of the multi-SIM UE belong to a same network operator's network, determining a first base station accessed by the connected SIM card of the multi-SIM user equipment; and sending paging signaling for paging the SIM card to be paged to the first base station.
Claims13
A paging method, applied to a core network device and comprising:
- receiving, by the core network device, User Equipment (UE) information of multi-SIM UE from a base station accessed by the multi-SIM UE, the UE information of the multi-SIM UE being firstly received by the base station from the multi-SIM UE through access stratum signaling;
- recording, by the core network device, the UE information of the multi-SIM UE in a local database;
- querying, by the core network device, a Subscriber Identification Module (SIM) card to be paged from the local database in response to determining that there is a need to page the SIM card to be paged;
- in case that the SIM card to be paged is found, determining, by the core network device, that UE to which the SIM card to be paged belongs is the multi-SIM UE and that multiple SIM cards of the multi-SIM UE belong to a same network operator's network;
- determining, by the core network device, a first base station currently being accessed by the multi-SIM UE;
- and
- sending, by the core network device to the first base station and an adjacent base station of the first base station, paging signaling for paging the SIM card to be paged;
- wherein the local database records the UE information of the multi-SIM UE of which multiple SIM cards belong to the same network operator's network;
- and the UE information of the multi-SIM UE comprises at least one of:
- International Mobile Subscriber Identification Numbers (IMSIs) of the SIM cards of the multi-SIM UE, or International Mobile Equipment Identities (IMEIs) corresponding to the SIM cards.

A paging method, applied to a base station and comprising:
- receiving, by the base station, User Equipment (UE) information of multi-SIM UE from the multi-SIM UE through access stratum signaling, wherein the UE information of the multi-SIM UE comprises at least one of:
- International Mobile Subscriber Identification Numbers (IMSIs) of Subscriber Identification Module (SIM) cards of the multi-SIM UE, or International Mobile Equipment Identities (IMEIs) corresponding to the SIM cards;
- and
- reporting, by the base station, the UE information of the multi-SIM UE to a core network device, wherein the UE information of the multi-SIM UE is recorded by the core network device in a local database when the UE information of the multi-SIM UE is received by the core network device, and
- wherein UE to which a SIM card to be paged belongs is the multi-SIM UE, and a paging signaling for paging the SIM card to be paged is sent by the core network device to a first base station currently being accessed by the multi-SIM UE and an adjacent base station of the first base station.
2 more elements
A paging method, applied to multi-SIM User Equipment (UE) and comprising:
- generating, by the multi-SIM UE, access stratum signaling comprising UE information of the multi-SIM UE, wherein the UE information of the multi-SIM UE comprises at least one of:
- International Mobile Subscriber Identification Numbers (IMSIs) of Subscriber Identification Module (SIM) cards of the multi-SIM UE, or International Mobile Equipment Identities (IMEIs) corresponding to the SIM cards;
- and
- sending, by the multi-SIM UE, the access stratum signaling to a base station so that the base station reports the access stratum signaling to a core network device,
- wherein the UE information of the multi-SIM UE comprised in the access stratum signaling is recorded by the core network device in a local database when the access stratum signaling is received by the core network device, and
- wherein UE to which a SIM card to be paged belongs is the multi-SIM UE, and a paging signaling for paging the SIM card to be paged is sent by the core network device to a first base station currently being accessed by the multi-SIM UE and an adjacent base station of the first base station.
