## Abstract

The present disclosure provides methods for releasing a reserved resource in a network. An operation method performed in a first communication node of a vehicle network includes generating a first frame including identification information of a stream transmitted through a reserved resource and a first indicator instructing to release the reserved resource; and transmitting the first frame to a second communication node.

## Claims

### Claim 1

An operation method performed in a first communication node of a vehicle network, the method comprising:
transmitting an advertisement frame, comprising priority information of a first stream, to reserve resource for a first stream;
generating the first frame comprising identification information based on the priority information of the first stream;
transmitting the first frame to a second communication node; and
receiving a second frame configured to indicate a completion of a release of a reserved resource between the first communication node and the second communication node from the second communication node,
wherein the first frame instructs to release the reserved resource,
wherein the second frame includes the identification information of the first stream,
wherein the identification information identifies the first stream transmitting through the reserved resource, and
wherein the identification information further indicates the reserved resource for the first stream among the reserved resources for each stream.

### Claim 2 (depends on 1)

The operation method according to claim 1, wherein the reserved resource is reserved based on a stream reservation protocol (SRP).

### Claim 3 (depends on 1)

The operation method according to claim 1, wherein the first frame further comprises a first indicator configured to instruct that the reserved resource be released.

### Claim 4 (depends on 1)

The operation method according to claim 1, wherein the first communication node supports at least one of a multiple medium access control reservation protocol (MMRP), a multiple virtual local area network reservation protocol (MVRP), or a multiple stream reservation protocol (MSRP).

### Claim 5 (depends on 1)

The operation method according to claim 1, wherein the first communication node is a talker or a listener.

### Claim 6 (depends on 1)

The operation method according to claim 1, wherein the first communication node is a centralized network configuration (CNC) node.

### Claim 7

An operation method performed in a first communication node of a vehicle network, the method comprising:
receiving an advertisement frame comprising priority information of a first stream to reserve resource for the first stream;
receiving a first frame comprising identification information of the first stream transmitted through a reserved resource based on the priority information of the first stream;
releasing the reserved resource for the first stream indicated by the identification information; and
transmitting a second frame configured to indicate a completion of a release of the reserved resource between the first communication node and a second communication node to the second communication node,
wherein the first frame instructs to release the reserved resource based on a monitoring result of the reserved resource,
wherein the second frame comprises the identification information of the first stream and
wherein the identification information further indicates the reserved resource for the first stream among the reserved resources for each stream.

### Claim 8 (depends on 7)

The operation method according to claim 7, wherein the reserved resource is reserved based on a stream reservation protocol (SRP).

### Claim 9 (depends on 7)

The operation method according to claim 7, wherein the first communication node supports at least one of a multiple medium access control reservation protocol (MMRP), a multiple virtual local area network reservation protocol (MVRP), or a multiple stream reservation protocol (MSRP).

### Claim 10 (depends on 7)

The operation method according to claim 7, wherein the first frame further comprises a first indicator configured to instruct that the reserved resource be released.

### Claim 11 (depends on 7)

The operation method according to claim 7, wherein the first communication node is a switch.

### Claim 12

An operation method performed in a first communication node of a vehicle network, the method comprising:
transmitting an advertisement frame, comprising priority information of a first stream, to reserve resource for a first stream;
generating the first frame comprising identification information based on the priority information of the first stream;
transmitting the first frame to a second communication node; and
receiving a second frame configured to indicate a completion of a release of a reserved resource between the first communication node and the second communication node from the second communication node,
wherein the first frame instructs to release the reserved resource,
wherein the second frame includes the identification information of the first stream,
wherein the identification information identifies the first stream transmitting through the reserved resource,
wherein the identification information further indicates the reserved resource for the first stream among the reserved resources for each stream, and
wherein the first frame is generated when the first communication node is requested to transmit a second stream which has a higher priority than the first stream.

### Claim 13

An operation method performed in a first communication node of a vehicle network, the method comprising:
transmitting an advertisement frame, comprising priority information of a first stream, to reserve resource for a first stream;
generating the first frame comprising identification information based on the priority information of the first stream;
transmitting the first frame to a second communication node; and
receiving a second frame configured to indicate a completion of a release of a reserved resource between the first communication node and the second communication node from the second communication node,
wherein the first frame instructs to release the reserved resource,
wherein the second frame includes the identification information of the first stream,
wherein the identification information identifies the first stream transmitting through the reserved resource,
wherein the identification information further indicates the reserved resource for the first stream among the reserved resources for each stream, and
wherein the first frame is generated when the second communication node is requested to transmit a second stream which has a higher priority than the first stream.
