Session transfer method and user equipment

A session transfer method, comprising:

• when sessions of a user equipment are transferred from a packet switched domain to a circuit switched domain and if the user equipment is involved in a video session and a voice session, determining a session in an active state and a session in an inactive state among the video session and the voice session;
• and
• releasing the session in the inactive state;
• and
• initiating transfer of the session in the active state, so that a network side transfers the session in the active state to the circuit switched domain.

A user equipment, comprising:

• a determination unit, configured to determine a session in an active state and a session in an inactive state among a video session and a voice session when sessions of the user equipment are transferred from a packet switched domain to a circuit switched domain and if the user equipment is involved in the video session and the voice session;
• and
• a release unit, configured to release the session in the inactive state, wherein the session in the inactive state is determined by the determination unit;
• and
• a transfer unit, configured to initiate transfer of the session in the active state, wherein the session in the inactive state is determined by the determination unit, so that a network side transfers the session in the active state to the circuit switched domain.
