Communication method and apparatus for realizing service continuity

A communication apparatus for realizing service continuity, the communication apparatus being for a remote user equipment to reselect a communication link after a communication operation fails or to initially select a communication link, being positioned in the remote user equipment, and comprising:

• a processor;
• and
• a memory configured to store instructions executable by the processor;
• wherein the processor is configured to perform:
• autonomously selecting, by the remote user equipment, a communication path communicating with the access network;
• and
• communicating with the access network by the remote user equipment using the communication path,
• wherein the communication path comprises at least one of:
• communicating with the access network via a first interface, wherein the first interface is configured to directly connect the remote user equipment to the access network;
• and
• communicating with the access network via a second interface, wherein the second interface is configured to connect the remote user equipment to the access network via a relay user equipment;
• wherein the autonomously selecting, by the remote user equipment, a communication path communicating with the access network means that the remote user equipment selects the first interface or the second interface based on a pre-configured rule to communicate with the access network;
• wherein the pre-configured rule is stored in a universal integrated circuit card (UICC) or a mobility equipment (ME) of the remote user equipment, or is received from the access network via a system broadcast message;
• and
• wherein in a case that the communication path comprises communicating with the access network via the second interface, the processor is further configured to perform:
• autonomously selecting or determining based on a second indication of the access network, by the remote user equipment, a communication technology used for communicating between the remote user equipment and the relay user equipment.

A non-transitory computer-readable storage medium storing a computer-executable instruction, wherein the computer-executable instruction is configured to execute a communication method for realizing service continuity, the method being for a remote user equipment to reselect a communication link after a communication operation fails or to initially select a communication link, and comprising:

• autonomously selecting, by the remote user equipment, a communication path communicating with the access network;
• and
• communicating with the access network by the remote user equipment using the communication path,
• wherein the communication path comprises at least one of:
• communicating with the access network via a first interface, wherein the first interface is configured to directly connect the remote user equipment to the access network;
• and
• communicating with the access network via a second interface, wherein the second interface is configured to connect the remote user equipment to the access network via a relay user equipment;
• wherein the autonomously selecting, by the remote user equipment, a communication path communicating with the access network means that the remote user equipment selects the first interface or the second interface based on a pre-configured rule to communicate with the access network;
• wherein the pre-configured rule is stored in a universal integrated circuit card (UICC) or a mobility equipment (ME) of the remote user equipment, or is received from the access network via a system broadcast message;
• wherein in a case that the communication path comprises communicating with the access network via the second interface, the method further comprises:
• autonomously selecting or determining based on a second indication of the access network, by the remote user equipment, a communication technology used for communicating between the remote user equipment and the relay user equipment.
