Methods, wireless device and nodes for managing reservation of bandwidth

A wireless device configured to provide an inquiry for reservation of bandwidth in a network, comprising a core network node for managing inquiries for reservation of bandwidth, wherein the wireless device comprises:

• a processing circuit and a memory operatively coupled to the processing circuit, wherein the processing circuit and memory are configured to send, to the core network node, the inquiry for reservation of bandwidth for the wireless device, wherein the inquiry comprises:
• information about a route to be travelled by the wireless device,
• a start time of when the wireless device is expected to start travelling the route, and
• an indication about the bandwidth to be reserved.

A radio network node configured for managing a command for reservation of bandwidth in a network, wherein the network comprises the radio network node and a core network node for managing inquiries for reservation of bandwidth, wherein the radio network node comprises:

• a processing circuit and memory operatively coupled to the processing circuit, wherein the processing circuit and memory are configured to:
• receive, from the core network node, a command for reservation of bandwidth for a wireless device, wherein the command comprises:
• an indication about the bandwidth to be reserved,
• information relating to one or more cells of the radio network node, in which one or more cells bandwidth is to be reserved according to the indication about the bandwidth to be reserved,
• a parameter indicating a period of time during which the wireless device is expected to make use of at least some of the bandwidth to be reserved, and
• an identity of the wireless device;
• and
• determine grant or denial of the command based on the period of time and based on available bandwidth of the radio network node.

A core network node configured for managing an inquiry for reservation of bandwidth in a network, comprising a plurality of radio network nodes and the core network node, wherein the core network node comprises:

• a processing circuit and memory operatively coupled to the processing circuit, wherein the processing circuit and memory are configured to:
• receive at the core network node, from a wireless device, the inquiry for reservation of the bandwidth for the wireless device, wherein the inquiry comprises information about a route to be travelled by the wireless device, a start time of when the wireless device is expected to start travelling the route, and an indication about the bandwidth to be reserved;
• and
• send, to each radio network node along the route, a command for reservation of the bandwidth to be reserved for the wireless device, wherein the command comprises the indication about the bandwidth to be reserved, information relating to one or more cells of the radio network node, in which one or more cells bandwidth is to be reserved according to the indication about the bandwidth to be reserved, a parameter indicating a period of time during which the wireless device is expected to make use of at least some of the bandwidth to be reserved, and an identity of the wireless device.
