Abstract: A cell selection method includes: when a terminal camps on a first network that does not support a voice service, and voice service needs to be initiated or received, falling back, by the terminal in a circuit switched fallback (CSFB) manner, to a second network that supports the voice service when the terminal fails to establish the voice service with the second network, saving, by the terminal, a location identifier of the first network and a location identifier of the second network to a blacklist. The blacklist is used by the terminal to choose to camp on a cell of the second network when performing CSFB subsequently.

Abstract: An application processing method and apparatus for an embedded universal integrated circuit card (eUICC) are disclosed. The method includes: activating, by a terminal device, an embedded universal integrated circuit card (eUICC); and selecting, by the terminal device, an Issuer Security Domain Root (ISD-R) application on the eUICC during an initialization process of the eUICC, to maintain a session between the terminal device and the eUICC. The session between the terminal device and the eUICC can be maintained during the initialization process of the eUICC.

Abstract: Embodiments include a method for installing a subscription profile, a terminal, and a server. The method includes obtaining, by a local profile assistant (LPA) in the terminal, metadata of a subscription profile, determining, based on an authorization file, whether use of each policy rule included in the metadata is allowed. The method further includes obtaining, by the LPA, the subscription profile when the use of each policy rule included in the metadata is allowed. The method further includes sending the subscription profile to an embedded universal integrated circuit card (eUICC) in the terminal. The method further includes determining, by the eUICC based on the authorization file, whether use of the subscription profile is allowed. The method further includes installing, by the eUICC, the subscription profile when the use of the subscription profile is allowed.

Abstract: Embodiments of the present invention disclose a subscription information download method, a related device, and a system. The method includes: receiving, by a first network device, a first request, where the first request is sent by a terminal after connecting to and attaching to a first network when the terminal has no effective profile, and is used to request to establish a network connection for downloading a profile; establishing, by the first network device, the network connection used for downloading the profile; and returning a response message for the first request to the terminal device, to inform the terminal device that the network connection has been successfully established.

Abstract: A data communication method, where a first device receives a request message from at least one second device, where the request message requests the first device to forward group data, and the request message carries a group identifier. The first device returns a response message to the at least one second device, where the response message carries a layer-2 address and an Internet Protocol (IP) address corresponding to the group identifier, and the first device sends the group data using the layer-2 address when receiving the group data sent by a third device to the IP address.
