Gateway node, user equipment and methods therein for handling an incoming call to the user equipment

A method performed by a first user equipment, for receiving an incoming call from a second user equipment, wherein a gateway node is serving the first user equipment in a terminating network, wherein the first user equipment is a called party of the incoming call, and wherein the second user equipment is a calling party of the incoming call, the method comprising:

• registering a set of subscriber numbers in a register, which set of subscriber numbers are selected by the first user equipment to be prioritized when the first user equipment is a called party;
• and
• receiving an incoming call from the second user equipment via the gateway node, which incoming call gets converted to an Enhanced Multi-level Precedence and Pre-emption service (EMLPP) call in the terminating network from the gateway node when the incoming call relates to a subscriber number that is comprised in the registered set of subscriber numbers, and wherein the incoming call is not prioritized in an originating network between the second user equipment and the gateway node, wherein
• the EMLPP call is a prioritized call achieving priority features over other calls in the terminating network, and
• the priority features comprise any one or more of the following priority features:
• Faster Call Setup Time,
• Queuing Capabilities,
• Precedence Capabilities, and
• Pre-emption Capabilities.

A gateway node, for handling an incoming call to a first user equipment, which gateway node is arranged to be serving the first user equipment in a terminating network, wherein the first user equipment is a called party of the incoming call, the gateway node is configured to:

• obtain information about whether or not the incoming call relates to a subscriber number that is comprised in a registered set of subscriber numbers registered by the first user equipment;
• based on the obtained information, determine whether the incoming call relates to a subscriber number that is comprised in the registered set of subscriber numbers;
• and
• as a result of determining that the incoming call relates to a subscriber number that is comprised in the registered set of subscriber numbers, convert the incoming call to an Enhanced Multi-level Precedence and Pre-emption service (EMLPP) call in the terminating network at the gateway node, wherein
• the EMLPP call is a prioritized call achieving priority features over other calls in the terminating network, and
• the priority features comprise any one or more of the following priority features:
• Faster Call Setup Time,
• Queuing Capabilities,
• Precedence Capabilities, and
• Pre-emption Capabilities.

A first user equipment for receiving an incoming call from a second user equipment, wherein a gateway node is arranged to serve the first user equipment in a terminating network, wherein the first user equipment is a called party of the incoming call, and wherein the second user equipment is a calling party of the incoming call, the first user equipment is configured to:

• register a set of subscriber numbers in a register, which set of subscriber numbers are arranged to be selected by the first user equipment to be prioritized when the first user equipment is a called party;
• and
• receive an incoming call from the second user equipment via the gateway node, which incoming call is arranged to get converted to an Enhanced Multi-level Precedence and Pre-emption service (EMLPP) call in the terminating network from the gateway node when the incoming call relates to a subscriber number that is comprised in the registered set of subscriber numbers, and wherein the incoming call is arranged to not be prioritized in an originating network between the second user equipment and the gateway node serving the first user equipment, wherein
• the EMLPP call is arranged to be a prioritized call achieving priority features over other calls in the terminating network, and
• the priority features comprise any one or more of the following priority features:
• Faster Call Setup Time,
• Queuing Capabilities,
• Precedence Capabilities, and
• Pre-emption Capabilities.
