Methods and vehicle, network node and user equipment for enabling efficient paging

A method, performed by a network node, for managing paging of a user equipment in a cellular radio access network, wherein the user equipment is page-able by the network node according to a first DRX cycle and based on position information of the user equipment, wherein the method comprises:

• receiving, from the vehicle and via the cellular radio access network, an identification of the user equipment, wherein the identification of the user equipment relates to the cellular radio access network,
• sending, to the user equipment, a control message instructing the user equipment to apply a second DRX cycle, wherein the second DRX cycle is longer than the first DRX cycle,
• receiving, from the vehicle, position information of the vehicle, and
• sending, based the position information of the vehicle, a paging message to the user equipment.

A vehicle configured for enabling a network node to manage paging of a user equipment, in a cellular radio access network, the vehicle comprising:

• a processing circuit;
• and
• memory comprising instructions executable by the processing circuit whereby the vehicle is operative to:
• receive, from the user equipment, an identification of the user equipment by use of a direct wireless communication connection between the vehicle and the user equipment, wherein the identification of the user equipment relates to the cellular radio access network,
• send, to the network node and via the cellular radio access network, the identification of the user equipment, whereby the network node is made aware of that position information of the vehicle is applicable to the user equipment,
• send, to the network node, the position information of the vehicle, whereby the network node, upon paging of the user equipment, sends a paging message, based on the position information of the vehicle, to the user equipment.
