Abstract
The present disclosure relates to systems and methods for obtaining and using Device-to-Device (D2D) related information for a node (e.g., a wireless device or a network node) in a cellular communications network to perform one or more mobility operations for a wireless device. Embodiments of a method of operation of a network node for operation in the cellular communications system are disclosed. In some embodiments, the method of operation of the network node in the cellular communications system comprises obtaining D2D related information for one or more nodes in the cellular communications system, and using the D2D related information to perform one or more mobility operations associated with the wireless device.
Claims22
A method of operation of a network node in a cellular communications system, comprising:
- obtaining Device-to-Device, D2D, related information for one or more nodes in the cellular communications system, the one or more nodes including a first wireless device such that the D2D related information comprises information, received from the first wireless device, related to a D2D capability of the first wireless device;
- and
- using the D2D related information to perform one or more mobility operations associated with the first wireless device, the one or more mobility operations comprising at least one of a group consisting of:
- a handover operation;
- a selection operation;
- and a reselection operation;
- wherein the network node is a radio network node or a core network node and wherein the D2D related information comprises at least one of a group consisting of:
- information indicative of a capability associated with one or more D2D activities of a predetermined type, purpose, application, or service;
- information indicative of a characteristic or type of a D2D activity, service, or application;
- and
- information indicative of a capability to support a predetermined type of scheduling for D2D activities;
- wherein the network node is a first radio network node, and the one or more nodes comprise the first wireless device and at least one of a group consisting of:
- a second wireless device that is capable of performing D2D operations associated with the first wireless device;
- the first radio network node that is serving the first wireless device;
- and
- a second radio network node of a target cell for connection by the first wireless device;
- and
- wherein the D2D related information comprises relative movement characteristics of the first wireless device with respect to the second wireless device.
A network node in a cellular communications system, comprising:
- at least one communication interface;
- at least one processor;
- and
- memory containing instructions executable by the at least one processor, whereby the network node is operative to:
- obtain Device-to-Device, D2D, related information for one or more nodes in the cellular communications system, the one or more nodes including a first wireless device such that the D2D related information comprises information, received from the first wireless device, related to a D2D capability of the first wireless device;
- and
- use the D2D related information to perform one or more mobility operations associated with the wireless device, the one or more mobility operations comprising at least one of a group consisting of:
- a handover operation;
- a selection operation;
- and a reselection operation;
- wherein the network node is a radio network node or a core network node and wherein the D2D related information comprises at least one of a group consisting of:
- information indicative of a capability associated with one or more D2D activities of a predetermined type, purpose, application, or service;
- information indicative of a characteristic or type of a D2D activity, service, or application;
- and
- information indicative of a capability to support a predetermined type of scheduling for D2D activities;
- wherein the network node is a first radio network node, and the one or more nodes comprise the first wireless device and at least one of a group consisting of:
- a second wireless device that is capable of performing D2D operations associated with the first wireless device;
- the first radio network node that is serving the first wireless device;
- and
- a second radio network node of a target cell for connection by the first wireless device;
- and
- wherein the D2D related information comprises relative movement characteristics of the first wireless device with respect to the second wireless device.
