Switch over without disconnection of access network

A second apparatus of a terminal device, comprising:

• a processor;
• a transceiver communicatively coupled to the processor, and
• at least one memory storing instructions that, when executed by the at least one processor, cause the second apparatus at least to:
• determine a switchover from a first traffic type associated with a first access point to a second traffic type associated with a second access point;
• transmit an indication of the switchover to the first access point, the indication being protected by a first key for a first connection between the terminal device and the first access point;
• and
• establish a second connection between the terminal device and the second access point, the second connection being protected by a second key.

A first access point comprising:

• a processor;
• and
• a transceiver communicatively coupled to the processor,
• at least one memory storing instructions that, when executed by the at least one processor, cause the first access point at least to:
• receive, from a terminal device, a first indication protected by a first key for a connection between the terminal device and the first access point;
• decrypt the first indication based on a first key to determine a switchover by the terminal device from a first traffic type associated with the first access point to a second traffic type associated with a second access point;
• and
• transmit a second indication of the switchover to the second access point.

A second access point comprising:

• a processor;
• a transceiver communicatively coupled to the processor, and
• at least one memory storing instructions that, when executed by the at least one processor, cause the second access point at least to:
• receive, from a first access point, an indication of a switchover by a terminal device from a first traffic type associated with the first access point to a second traffic type associated with the second access point, a first connection between the terminal device and the first access point being protected by a first key;
• and
• establish a second connection between the terminal device and the second access point, the second connection being protected by a second key.
