Abstract: This disclosure discloses communication methods and apparatuses. One communication method comprises: receiving, by a terminal apparatus, a first notification, wherein the first notification comprises notification content and area information indicating a geographical area; determining, by the terminal apparatus, that the terminal apparatus is not located in the geographical area; determining, by the terminal apparatus, that the terminal apparatus enters the geographical area within a preset time period after determining that the terminal apparatus is not located in the geographical area; and in response to determining that the terminal apparatus enters the geographical area within the preset time period, indicating, by the terminal apparatus to a user, the notification content.

Abstract: Example communication methods and apparatus are described. One example method includes receiving a first message by a terminal device from an access network device, where the first message indicates the terminal device to be handed over to a target cell or to be redirected to a target frequency. If the handover to the target cell fails or the redirection to the target frequency fails, the terminal device searches for an acceptable cell or a suitable cell. According to some embodiments of this application, an emergency call delay can be reduced.

Abstract: The present disclosure provides a voice call processing method and a terminal device. The method includes: when a terminal meets at least one of two preset conditions, performing handover from a Long Term Evolution LTE network currently accessed by the terminal to a non-LTE standard network, and performing a circuit switched CS voice call process on the non-LTE standard network. The voice call processing method provided in embodiments of the present invention increases a voice call completion rate of a terminal and meets a user experience requirement.

Abstract: A packet processing method, apparatus, and device are disclosed. The method includes: receiving, by a forwarding plane, an item from a control plane of the forwarding plane, where the item includes an identifier of a connected terminal; receiving an access protocol packet; when the access protocol packet is not an authentication start packet, determining, by the forwarding plane according to the identifier of the connected terminal, whether a terminal served by the access protocol packet is the connected terminal; and discarding, by the forwarding plane, the access protocol packet when the access protocol packet is not the authentication start packet and when the terminal served by the access protocol packet is not the connected terminal. The method improves user experience.
