METHOD AND APPARATUS FOR PROVIDING USER PLANE OR CONTROL PLANE POSITION SERVICES

摘要

A dual SIM mobile terminal, such as a Dual SIM Dual Active (DSDA) mobile terminal, connects to a network and performs a user plane or control plane positioning session through the network. When the positioning session is originated by the mobile terminal, either SIM card may be used to connect to its associated network. When the positioning session is originated by another entity in the network, either SIM card may be used for the positioning session. When the mobile terminal connects to a network for an emergency call using either SIM card and an emergency positioning session is performed through the network, the emergency positioning session is permitted only during the emergency call and an emergency callback period and permitted only on a subscription on which the emergency call originated, and no non-emergency positioning sessions with either SIM card is permitted during the emergency positioning session or emergency call.
