Background

In order to support direct communication between UEs (user equipment), a sidelink communication method is introduced, and the UEs can communicate through a PC-5 interface (direct communication interface).

Fig. 1 is a flowchart illustrating a temporary identity scheduling method according to an exemplary embodiment, which is used in a first relay device, as shown in fig. 1, and includes the following steps.

In step S101, a temporary identification of at least one device in the side uplink is received.

Wherein at least one device in the side-link includes at least one of a peer device, a relay device, and a remote device. The Sidelink (SL) supports communication between UEs, and includes a physical sidelink control channel (Physical Sidelink Control Channel, PSCCH) and a physical sidelink shared channel ((Physical Sidelink Shared Channel, PSSCH), the transmitting UE transmits sidelink control information (Sidelink Control Information, SCI) on the PSCCH channel, and the SCI of the second stage is transmitted on the PSSCH channel, where the SCI carries a resource location of transmission data, a source identifier of the transmitting UE, and a destination identifier of the receiving UE.

The sending UE is a party sending data or signaling, and may be a relay UE, a remote UE or an opposite UE; the receiving UE is a party receiving data or signaling, and may be a relay UE, a remote UE, or a peer UE. In the present disclosure, one UE may not directly connect to a base station, but rather, communicate with the base station through a relay of another UE, where a UE that is not connected to the base station is called a remote UE (remote UE), a UE that provides a relay function is called a relay UE (relay UE), and this architecture is called a U2N (UE to NW) relay. The equipment in the side uplink comprises a far-end UE, a relay UE and an opposite-end UE, wherein the opposite-end UE is the UE which communicates with the far-end UE through the relay UE.

For ease of description, the present disclosure may refer to a first relay UE as a first relay device, a first remote UE as a first remote device, a first peer UE as a second relay device, a second peer UE as a second remote device, and the like.

The side-link may be a D2D (Device to Device) link, such as a handset-to-handset communication link or a handset-to-wearable communication link; in the internet of vehicles, the side links may also be Vehicle-to-Vehicle (Vehicle to Vehicle, V2V) communication links, vehicle-to-person (Vehicle to Pedestrian, V2P) communication links, vehicle-to-infrastructure (Vehicle to Infrastructure, V2I) links, or Vehicle-to-any device (V2X) communication links.

Side-uplink communications support three modes of communication: unicast, multicast and broadcast. Unicast refers to that a sending UE transmits information to a receiving UE, and each receiving UE in unicast corresponds to a destination identifier; multicast is that a sending UE transmits information to a plurality of receiving UEs, and each group of receiving UEs in the multicast corresponds to a destination identifier; the broadcast is that a transmitting UE transmits information to all receiving UEs within its network coverage, and in the broadcast, all receiving UEs within the network coverage of the transmitting UE correspond to a destination identifier.

In order to support direct communication between UEs, in this embodiment, data communication may be established between UEs through a 5G (fifth generation mobile communication system) and a 4G (fifth generation mobile communication system) communication technology, and based on a side uplink communication mode, direct communication may be performed between UEs through a PC-5 interface. In the embodiment of the disclosure, the UE may directly communicate with other UEs by using a sidelink communication manner based on multiple network formats, and it should be noted that the multiple network formats may include 4G, 5G, or 4G, 5G evolution technologies, and the like.

In the present disclosure, there may be a plurality of relay groups in a network, each relay group including a remote device, a relay device, and a peer device. For example, referring to fig. 2, a first relay device in a first relay group may be used as a link for communication between a first peer device and a first remote device, and a second relay device in a second relay group may be used as a link for communication between a second peer device and a second remote device.

When the opposite terminal equipment distributes temporary identifiers for the far terminal equipment, the relay equipment is required to forward, and when the far terminal equipment distributes temporary identifiers for the opposite terminal equipment, the relay equipment is also required to forward, so that the relay equipment can receive the temporary identifiers distributed for the opposite terminal equipment and the far terminal equipment in the side uplink respectively.

The relay device can acquire the temporary identifier from the opposite terminal device and/or the far terminal device under the condition that the relay device receives the temporary identifier distributed by the opposite terminal device for the far terminal device; in the case where the relay device receives a temporary identity assigned by the remote device to the opposite device, the relay device may obtain the temporary identity from the remote device and/or the opposite device. Specifically, referring to fig. 2, when the first relay device determines the temporary identifier of the first remote device, the first relay device receives the temporary identifier of the first remote device from the first remote device, and/or the first relay device receives the temporary identifier of the first remote device from the first peer device; when the first relay device determines the temporary identifier of the first peer device, the first relay device receives the temporary identifier of the first peer device from the first peer device, and/or the first relay device receives the temporary identifier of the first peer device from the first remote device.

Wherein the temporary identity is generated for the purpose of saving signalling. For example, when the remote device is used as a transmitting device to transmit data to the opposite device, the source address of the remote device and the destination address of the opposite device need to be indicated, the relay device can forward the data according to the source address and the destination address, and the opposite device as a receiving device can receive the data according to the source address. In this process, the character string of the signaling corresponding to the source address and the destination address is long, so that the remote device and the relay device can realize data transmission only by using more network resources, which wastes signaling and causes network resources to be occupied.

In order to save signaling, when the remote device sends data to the opposite device, the remote device can carry a temporary identifier allocated by the remote device to the opposite device in the data, for example, 1, and the character string of the temporary identifier is shorter, so that signaling is saved, and therefore, the remote device and the relay device can use fewer network resources to realize data transmission, and part of network resources are released.

In step S102, in response to the temporary identity of the device having a temporary identity collision, a collision indication is sent to a peer device of the device.

The device and the opposite device of the device communicate through a relay device, for example, in the case that the device is the opposite device, the opposite device of the device may be a remote device, and in the case that the device is a remote device, the opposite device of the device may be the opposite device. That is, two devices connected to each other through the relay device are a counterpart device and a remote device. The opposite terminal equipment and the far-end equipment can mutually allocate temporary identifications for each other, so when the temporary identifications of the equipment have temporary identification conflicts, conflict indications can be sent to the opposite terminal equipment of the equipment, so that the opposite terminal equipment can reallocate the temporary identifications for the equipment. The relay device sends the conflict indication to the opposite terminal device or forwards the conflict indication to the opposite terminal device through the far-end device.

The mutual allocation of temporary identifiers between the opposite terminal equipment and the far-end equipment can save signaling and release part of network resources, but the situation of temporary identifier conflict exists, so that the relay equipment cannot correctly forward data.

As shown in fig. 2, for example, C may forward, as the first relay device, the temporary identifier allocated by the first peer device B to the first remote device D, and C may also receive, as the second remote device, the temporary identifier returned by the second peer device a to itself of the device C through the second relay device B. Thus, there is a possibility of a resolution error, and if the resolution is wrong, data is lost.

In order to avoid data loss, the disclosure proposes that, in a case where the relay device receives that the temporary identifier of the device has a temporary identifier conflict, a conflict indication is sent to a peer device of the device.

For example, when the first relay device determines that the temporary identifier allocated to the first remote device by the first peer device is the same as the temporary identifier of the first relay device itself, it is confirmed that the first relay device collides with the temporary identifier of the first remote device, and at this time, a collision indication may be sent to the first peer device.

The temporary identifier conflict refers to that the relay device cannot distinguish the devices corresponding to the two temporary identifiers according to the two temporary identifiers received by the relay device.

The conflict indication carries two pieces of information of the conflict of the temporary identifications and is used for indicating opposite terminal equipment of the equipment to reallocate the temporary identifications for the equipment according to the conflict indication; the collision indication may also carry a suggested temporary identity of the first relay device, where the suggested temporary identity is different from the collided temporary identity, so as to distinguish from the collided temporary identity.

Reassignment in any embodiment of the present disclosure may include: before the device does not receive the temporary identifier allocated by the opposite terminal device of the device, determining that temporary conflict exists, and reallocating the temporary identifier for the device by the opposite terminal device of the device.

For example, before the remote device has not received the temporary identifier allocated to the opposite device, the relay device determines that the temporary identifier to be allocated to the remote device conflicts with the temporary identifier of the relay device itself, so as to avoid that the relay device cannot distinguish different devices according to the same temporary identifier, and the relay device sends a conflict indication to the opposite device of the device.

Fig. 3 is a flowchart illustrating a temporary identity scheduling method according to an exemplary embodiment, and the temporary identity scheduling method is used in the first relay device, as shown in fig. 3, and includes the following steps.

In step S201, a temporary identification of at least one device in the side uplink is received.

For example, the method for receiving the temporary identifier of the device in the side uplink in the embodiment of the present disclosure may refer to step S101 described above, and will not be described in detail. At least one device comprises a first remote device or a first peer device, and the step of sending a collision indication to the peer device of the device in response to the existence of a temporary identity collision for the temporary identity of the device comprises at least one of step S202.

In step S202, in response to the first relay device having a temporary identity conflict with the first remote device, sending a conflict indication to the first peer device; transmitting a collision indication to the first remote device in response to the first relay device having a temporary identity collision with the first peer device; the first opposite terminal device is an opposite terminal device connected with the first remote terminal device through the first relay device.

Under the condition that the first relay equipment and the first remote equipment have temporary identification conflict, the first relay equipment directly forwards conflict indication to the first opposite terminal equipment or forwards conflict indication to the first opposite terminal equipment through the first remote equipment; and under the condition that the first opposite terminal equipment and the first relay equipment have the temporary identification conflict, the first relay equipment directly forwards the conflict indication to the first far-end equipment or forwards the conflict indication to the first far-end equipment through the first opposite terminal equipment.

For example, if the first relay device has the capability of resolving and processing the forwarding content, the temporary identifier allocated to the first remote device by the first peer device may be directly received, and a first collision indication is generated when it is determined that the temporary identifier collides with the temporary identifier of the first peer device; and then the first conflict indication is directly sent to the first opposite terminal equipment, the first opposite terminal equipment reallocates the temporary identifier for the first remote terminal equipment according to the first conflict indication, and the reallocated temporary identifier is forwarded to the first remote terminal equipment through the first relay equipment so that the first remote terminal equipment uses the reallocated temporary identifier.

If the first relay device does not execute the function of analyzing and processing the forwarding content, the content of forwarding data cannot be determined, at this time, the first relay device can forward the temporary identifier allocated by the first opposite terminal device to the first remote terminal device, then receive the temporary identifier determined by the first remote terminal device, and generate a first conflict indication under the condition that the temporary identifier sent by the first remote terminal device conflicts with the temporary identifier of the first relay device; and the first conflict indication is forwarded to the first remote equipment, the first remote equipment analyzes and determines the first conflict indication, and the first conflict indication is returned to the first relay equipment and is forwarded to the first opposite-end equipment through the first relay equipment.

In some embodiments, a collision indication may be sent to a first peer device in response to the first relay device having a temporary identity collision with the first remote device.

For example, as shown in fig. 2, since the remote device allocates a temporary identifier to the opposite device, the opposite device allocates a temporary identifier to the remote device, when the first relay device is used as the second remote device, the temporary identifier allocated to the first remote device, which is received by the first relay device from the second opposite device, is the temporary identifier of the first relay device itself; the temporary identifier received by the first relay device from the first peer device is of the first remote device, and if two temporary identifiers collide, the first relay device cannot distinguish whether the temporary identifier is of its own or of the first remote device.

At this time, the first relay device may send a collision indication to the first peer device in response to the first relay device having a temporary identifier collision with the first remote device, so as to instruct the first peer device to reassign a temporary identifier different from the temporary identifier of the first remote device to the first remote device.

In some embodiments, a collision indication may be sent to the first remote device in response to the first relay device having a temporary identity collision with the first peer device.

For example, referring to fig. 2, the temporary identifier received by the first relay device from the second peer device is a temporary identifier of the first relay device itself, and if two temporary identifiers conflict, the first relay device cannot distinguish whether the temporary identifier is of its own or the first peer device.

At this time, the first relay device may send a collision indication to the first remote device in response to the first relay device having a temporary identifier collision with the first peer device, so as to instruct the first remote device to reassign, for the first peer device, a temporary identifier different from the temporary identifier of the first peer device.

In some embodiments, the collision indication may be sent to the first remote device in response to the first relay device having a collision of temporary identifications with the first peer device, and the collision indication may be sent to the first peer device in response to the first relay device having a collision of temporary identifications with the first remote device.

For example, referring to fig. 2, when the temporary identifier of the first relay device, the temporary identifier of the first peer end, and the temporary identifier of the first remote device collide, it indicates that the first relay device cannot distinguish whether the temporary identifier is of itself, the first remote device, or the first peer end device.

At this time, the first relay device responds that the first relay device collides with the temporary identifier of the first remote device, and sends a conflict indication to the first opposite terminal device, so as to instruct the first opposite terminal device to redistribute the temporary identifier, which is different from the temporary identifier of the first remote device, for the first remote device, so as to distinguish the temporary identifier from the temporary identifier of the first relay device; and the first relay device responds that the first relay device and the first opposite terminal device have temporary identifier conflict, sends a conflict indication to the first far-end device, and indicates the first far-end device to redistribute identifiers different from the temporary identifiers of the first opposite terminal device for the first opposite terminal device so as to be distinguished from the temporary identifiers of the first relay device.

Wherein, in the case that the first relay device collides with the temporary identifier of the first peer device, and the first relay device collides with the temporary identifier of the first peer device, the temporary identifier reassigned to the first peer device by the first peer device is different from the temporary identifier reassigned to the first peer device by the first peer device.

According to the technical scheme, when the first relay equipment receives the conflict between the temporary identifier of the first opposite terminal equipment and the temporary identifier of the first relay equipment, a conflict indication can be sent to the first far-end equipment so as to inform the first far-end equipment that the temporary identifier conflict exists between the first opposite terminal equipment and the first relay equipment, the first far-end equipment is instructed to reallocate the temporary identifier for the first opposite terminal equipment, and the situation that the first relay equipment cannot distinguish the temporary identifier of the first opposite terminal equipment from the temporary identifier of the first relay equipment is avoided; when the first relay device receives that the temporary identifier of the first remote device is the same as the temporary identifier of the first relay device, a conflict indication can be sent to the first opposite terminal device to inform the first opposite terminal device that the first remote device has temporary identifier conflict with the first relay device, the first opposite terminal device is instructed to reassign the temporary identifier for the first remote device, and the situation that the first relay device cannot distinguish the temporary identifier of the first remote device from the temporary identifier of the first relay device is avoided.

Fig. 4 is a flowchart illustrating a temporary identity scheduling method according to an exemplary embodiment, which is used in the first relay device, as shown in fig. 4, and includes the following steps.

In step S301, a temporary identity of at least one device in the side uplink is received.

For example, the method for receiving the temporary identifier of the device in the side uplink in the embodiment of the present disclosure may refer to step S101 described above, and will not be described in detail.

In step S302, in a case where the first temporary identity of the first relay device is the same as the second temporary identity of the first remote device, it is determined that there is a temporary identity conflict between the first relay device and the first remote device.

The first relay device transmits a second temporary identifier allocated to the first remote device by the first opposite terminal device to the first remote device in the first relay group; the first relay device receives a first temporary identifier assigned to the first relay device by the second peer device when the first relay device is in the second relay group as the second remote device. In any embodiment of the disclosure, the first relay group and the second relay group have the same device, which may cause a phenomenon of collision of temporary identifications, for example, the first relay group and the second relay group have the same B and C.

Wherein, when the first temporary identifier of the first relay device is identical to the second temporary identifier of the first remote device, the first relay device cannot distinguish whether the first temporary identifier and the second temporary identifier should be self or need to be forwarded to the first remote device, so there may be a temporary identifier conflict.

In step S303, in response to the first relay device having a temporary identifier conflict with the first remote device, a first conflict indication is sent to the first peer device, where the first conflict indication is used to instruct the first peer device to reallocate a temporary identifier for the first remote device.

When the first relay device determines that the first temporary identifier collides with the second temporary identifier, a first collision indication can be generated, and the first collision indication is directly forwarded to the first opposite terminal device.

For example, if the first relay device has the capability of resolving the forwarding content, the first collision indication may be directly sent to the first peer device, and the first peer device reassigns a temporary identifier to the first remote device according to the first collision indication, where the temporary identifier is different from the first temporary identifier and the second temporary identifier, and the reassigned temporary identifier is forwarded to the first remote device through the first relay device, so that the first remote device uses the reassigned temporary identifier.

The first collision indication may carry a temporary identifier proposed by the first relay device for the first remote device, the first peer device may use the proposed temporary identifier to be reassigned to the first remote device, where the proposed temporary identifier is different from the first temporary identifier and the second temporary identifier, and of course, the first peer device may also not use the proposed temporary identifier, but may itself regenerate a temporary identifier different from the first temporary identifier and the second temporary identifier to be reassigned to the first remote device.

In any embodiment of the present disclosure, the first peer device may be a first remote device, and the first remote device may be a first peer device, so the above steps may be converted into the first remote device to allocate a temporary identifier to the first peer device, and specific steps are similar to the above steps and are not repeated.

Through the technical scheme, when the first relay device receives the second temporary identifier of the first remote device and the first temporary identifier of the first relay device, it is determined that the temporary identifier conflict exists, a first conflict indication can be sent to the first opposite terminal device at this time to indicate the first opposite terminal device to reassign the temporary identifier to the first remote device according to the first conflict indication, and when the first remote device has the reassigned temporary identifier different from the first temporary identifier, the first relay device can distinguish the temporary identifier of the first remote device from the temporary identifier of the first relay device according to the different temporary identifier, so that the phenomenon of data loss is avoided.

Fig. 5 is a flowchart illustrating a temporary identity scheduling method according to an exemplary embodiment, and the temporary identity scheduling method is used in the first relay device, as shown in fig. 5, and includes the following steps.

In step S401, a temporary identification of at least one device in the side uplink is received.

In step S402, in a case where the first temporary identifier of the first relay device is the same as the second temporary identifier of the first remote device, it is determined that there is a temporary identifier conflict between the first relay device and the first remote device.

For example, in the embodiment of the present disclosure, the method for determining that the first relay device collides with the temporary identifier of the first remote device may refer to step S302, which is not described herein.

In step S403, in response to the first relay device having a temporary identity conflict with the first remote device, sending the first conflict indication to the first remote device; the first collision indication is used for indicating the first opposite end device to reallocate temporary identification for the first far end device.

When the first relay device determines that the first temporary identifier collides with the second temporary identifier, a first collision indication can be generated, and the first collision indication is forwarded to the first opposite-end device through the first remote-end device.

For example, if the first relay device does not have the capability of resolving the forwarding content, the first conflict indication may be directly sent to the first remote device, after the first remote device resolves and determines the first conflict indication, the first conflict indication is forwarded to the first relay device, and the first relay device is forwarded to the first peer device, where the first relay device plays a role in forwarding data, and does not resolve the data forwarded by the first peer device and the first remote device; the first opposite terminal equipment reallocates the temporary identifier for the first remote terminal equipment according to the first conflict indication, the temporary identifier is different from the first temporary identifier and the second temporary identifier, and the reallocated temporary identifier is forwarded to the first remote terminal equipment through the first relay equipment, so that the first remote terminal equipment uses the reallocated temporary identifier.

Through the technical scheme, when the first relay device receives that the second temporary identifier of the first remote device is identical to the first temporary identifier of the first relay device, it is determined that the temporary identifier conflict exists, at this time, a first conflict indication can be sent to the first remote device, the first remote device returns the first conflict indication to the first opposite terminal device through the first relay device, so that the first opposite terminal device is instructed to redistribute the temporary identifier for the first remote device according to the first conflict indication, and when the first remote device has the redistributed temporary identifier which is different from the first temporary identifier, the relay device can distinguish the temporary identifier of the first remote device from the temporary identifier of the first relay device according to the different temporary identifiers, so that the phenomenon of data loss is avoided.

Fig. 6 is a flowchart illustrating a temporary identity scheduling method according to an exemplary embodiment, which is used in the first relay device, as shown in fig. 6, and includes the following steps.

In step S501, a temporary identity of at least one device in the side uplink is received.

In step S502, in a case where the third temporary identifier of the first peer device is the same as the fourth temporary identifier of the second peer device, it is determined that there is a temporary identifier conflict between the first peer device and the second peer device.

The first relay device may not only receive the third temporary identifier of the first peer device and the second temporary identifier of the first remote device, but also determine, as the second remote device, the fourth temporary identifier allocated to the second peer device.

In the second relay group, for example, since the second remote device and the second peer device may allocate temporary identities to each other, the first relay device may directly determine the temporary identity of the second peer device as the second remote device.

When the first relay device determines that the temporary identifier of the first opposite terminal device is the same as the temporary identifier of the second opposite terminal device, the second relay device cannot determine whether the temporary identifier is to be forwarded to the second opposite terminal device by the second remote terminal device or the second relay device is used as the first opposite terminal device, the first remote terminal device is allocated to the second relay device, and the temporary identifier of the second opposite terminal device conflicts with the temporary identifier of the first opposite terminal device.

In step S503, in response to the first peer device having a temporary identity conflict with the second peer device, sending a conflict indication to the peer device of the device; the second opposite terminal device is an opposite terminal device connected with the second remote terminal device through the second relay device.

When the first relay device determines that the temporary identifier of the first opposite terminal device conflicts with the temporary identifier of the second opposite terminal device, the first relay device can directly and newly allocate the temporary identifier to the second opposite terminal device, wherein the temporary identifier is different from the temporary identifier of the second opposite terminal device and the temporary identifier of the second relay device, the temporary identifier is carried in a conflict indication, and the second opposite terminal device analyzes the conflict indication and acquires the temporary identifier which is allocated by the second far terminal device for the second opposite terminal device from the conflict indication.

The conflict indication sent by the first relay device for the second remote device carries a temporary identifier allocated to the second opposite device.

Of course, the second relay device in the second relay group may also determine whether the temporary identifier of the second peer device conflicts with the temporary identifier of the second peer device, and when the second peer device receives the two reassigned temporary identifiers, one temporary identifier is selected from the two reassigned temporary identifiers; the second relay device in the second relay group may not need to determine whether the temporary identifier of the second peer device collides with the own temporary identifier, and may determine that the second relay device is the first relay device.

In any embodiment of the present disclosure, the first relay device may be a second relay device, and the second relay device may also be a first relay device, so that the second relay device may perform a function implemented by the first relay device, and the first relay device may also perform a function implemented by the second relay device.

Through the technical scheme, when the first relay device determines that the temporary identifier of the first opposite terminal device is in conflict with the first temporary identifier of the second opposite terminal device, the conflict indication can be sent to the second opposite terminal device, and the second opposite terminal device analyzes the conflict indication to obtain the reassigned temporary identifier. When the second remote device has a reassigned temporary identifier different from the fourth temporary identifier, the second relay device can distinguish the temporary identifier of the second opposite device from the temporary identifier thereof according to the different temporary identifiers, so as to avoid the phenomenon of data loss.

Fig. 7 is a flowchart illustrating a temporary identity scheduling method according to an exemplary embodiment, which is used in the first relay device, as shown in fig. 7, and includes the following steps.

In step S601, receiving a temporary identifier and an identifier of a first peer device sent by the first remote device; and/or receiving the temporary identifier and the identifier of the first remote device sent by the first opposite device.

In some embodiments, receiving the temporary identifier and the identifier of the first peer device sent by the first remote device may specifically include: receiving an identifier and a temporary identifier of first opposite terminal equipment sent by first remote terminal equipment; according to the identification of the first opposite terminal equipment, determining the opposite terminal equipment corresponding to the identification as first opposite terminal equipment of the opposite terminal of the first far-end equipment; and sending the temporary identifier distributed by the first remote equipment for the first opposite-end equipment to the first opposite-end equipment.

Wherein the first remote device, as a party that allocates a temporary identifier to the first peer device, may determine the temporary identifier allocated to the first peer device; and there may be a plurality of counterpart devices communicating with the first remote device through the first relay device, the first remote device needs to determine an object for transmitting the temporary identification through the identification of the counterpart device.

For example, the first remote device has a plurality of identifiers of the opposite end devices, where the identifier may uniquely identify one opposite end device, and when the first remote device determines that the temporary identifier needs to be allocated to the first opposite end device, the identifier of the first opposite end device and the temporary identifier allocated to the first opposite end device may be sent to the first relay device; the first relay device determines that the distribution object of the temporary identifier is the first opposite terminal device according to the identifier, so the first relay device sends the temporary identifier to the first opposite terminal device corresponding to the identifier.

For example, the opposite terminal device communicating with the first remote terminal device through the first relay device has B and F, when the first remote terminal device determines that the temporary identifier is to be reassigned to B according to the collision indication, the identifier and the temporary identifier of B may be sent to the first relay device, and the first relay device determines that the assignment object of the temporary identifier is B according to the identifier, so that the temporary identifier is sent to B corresponding to the identifier.

In some embodiments, receiving the temporary identifier and the identifier of the first remote device sent by the first peer device may specifically include: receiving an identifier and a temporary identifier of the first remote device, which are sent by the first opposite device; determining the first remote equipment as the first opposite-end equipment according to the identification of the first remote equipment; and sending the temporary identifier allocated by the first opposite terminal equipment to the first remote terminal equipment.

Wherein the first peer device, as a party that allocates a temporary identifier to the first remote identifier, may determine the temporary identifier allocated to the first remote device; and there may be a plurality of remote devices communicating with the first peer device through the first relay device, the first peer device needs to determine the object to send the temporary identification.

For example, the first peer device has a plurality of identifiers of remote devices, where the identifier may uniquely identify one remote device, and when the first peer device determines that a temporary identifier needs to be allocated to the first remote device, the identifier of the first remote device and the temporary identifier allocated to the first remote device may be sent to the first relay device; the first relay device determines that the distribution object of the temporary identifier is the first remote device according to the identifier, so the first relay device forwards the temporary identifier to the first remote device corresponding to the identifier.

In some embodiments, the temporary identifier and the identifier of the first peer device sent by the first remote device may also be received; and receiving the temporary identifier and the identifier of the first remote device sent by the first opposite device.

When the first opposite-end device allocates a temporary identifier to the first remote-end device, the identifier of the first remote-end device and the temporary identifier allocated to the first remote-end device need to be sent to the first relay device, and the first relay device sends the temporary identifier to the first remote-end device corresponding to the identifier according to the identifier; when the first remote device allocates a temporary identifier to the first peer device, the first remote device needs to send the identifier of the first peer device and the temporary identifier allocated to the first peer device to the first relay device, and the first relay device sends the temporary identifier to the first peer device corresponding to the identifier according to the identifier.

The method for determining the corresponding opposite terminal equipment or the remote terminal equipment according to the identifiers can be applied to the distribution of the temporary identifiers before the temporary identifiers are not in conflict, and can also be applied to the redistribution of the temporary identifiers after the temporary identifiers are in conflict, and the specific application scene is not limited in this disclosure.

In step S602, in response to the temporary identity of the device having a temporary identity collision, a collision indication is sent to a peer device of the device.

For example, the step of sending the collision indication in the embodiment of the present disclosure may refer to the step S102, which is not described herein.

Through the technical scheme, after the first relay equipment receives the temporary identifier and the identifier of the remote equipment, the temporary identifier can be forwarded to the remote equipment corresponding to the identifier; after the first relay device receives the temporary identifier and the identifier of the opposite terminal device, the temporary identifier may also be forwarded to the opposite terminal device corresponding to the identifier. So that the first opposite terminal equipment can distribute the temporary identifier to the correct first far-end equipment, and the first far-end equipment can also distribute the temporary identifier to the correct first opposite terminal equipment, thereby avoiding the occurrence of the situation of false temporary identifier distribution.

Fig. 8 is a flowchart of a temporary identity scheduling method according to an exemplary embodiment, and as shown in fig. 8, the temporary identity scheduling method is used in a first remote device, and includes the following steps.

In step S701, the collision indication sent by the first relay device is forwarded to the devices in the side uplink.

The device in the side uplink may be the first relay device and/or the first peer device, and the collision indication carries a temporary identifier of the first peer device, which is proposed by the first relay device to be allocated to the first remote device, where the temporary identifier is different from the temporary identifier of the first remote device.

After determining that the temporary identifier of the first relay device conflicts with the temporary identifier of the first remote device, the first relay device forwards a conflict indication to the first remote device; the first remote device forwards the conflict indication to the first relay device, and the first relay device forwards the conflict indication to the first opposite terminal device; the first opposite terminal equipment reallocates the temporary identifier for the first remote terminal equipment according to the conflict indication; or the first relay device directly sends the conflict indication to the first opposite terminal device after determining that the temporary identifier of the first relay device conflicts with the temporary identifier of the first remote terminal device.

The collision indication carries a temporary identifier which the first relay device recommends to be distributed to the first remote device by the first opposite terminal device, and the temporary identifier is different from the temporary identifier of the first remote device.

In step S702, a temporary identification of a device in the side uplink is received.

When the first opposite terminal device receives the conflict indication determined by the first relay device or the first remote terminal device, the temporary identification suggested in the conflict indication can be used for reallocating the temporary identification for the first remote terminal device.

The first peer device sends the reassigned temporary identity to the first relay device, which forwards the reassigned temporary identity to the first remote device. After determining the temporary identifier of the first remote device, the first remote device may also forward the temporary identifier of the first remote device to other relay devices or other peer devices.

By the technical scheme, when the first relay device receives that the temporary identifier of the device in the side uplink has the temporary identifier conflict, a conflict indication can be sent to the first opposite terminal device so as to inform the device in the side uplink that the first relay device has the conflict with the temporary identifier of the first remote terminal device, and further the first remote terminal device receives the reassigned temporary identifier returned by the device in the side uplink, so that the situation of data loss caused by the temporary identifier conflict is avoided.

Fig. 9 is a flowchart of a temporary identity scheduling method according to an exemplary embodiment, and as shown in fig. 9, the temporary identity scheduling method is used in a first remote device, and includes the following steps.

In step S801, a collision indication sent by the first relay device is forwarded to a device in the side uplink.

For example, the step of forwarding the collision indication in the embodiment of the present disclosure may refer to the above step S701, and will not be described again.

In step S802, a temporary identifier sent by the first relay device is received, and/or a temporary identifier sent by a first peer device of the first remote device is received.

The first remote device interacts with the first relay device, so the first remote device can receive the temporary identifier forwarded to the first remote device by the first relay device, the first remote device can be a new identifier receiver, and the first opposite device receives the temporary identifier forwarded to the first remote device by the first relay device.

In some embodiments, the first remote device may receive the temporary identity sent by the first relay device.

Under the condition that the first relay equipment can analyze the forwarding content, the first relay equipment can analyze the forwarding content to obtain the temporary identifier which is distributed to the first remote equipment by the first opposite terminal equipment, so that the first relay equipment can directly receive the temporary identifier from the first opposite terminal equipment and send the temporary identifier to the first remote equipment.

In this process, the first remote UE acts as the destination UE and the first relay device acts as the source UE.

In an example, when the temporary identifier sent by the first relay device is the identifier of the first remote device and the temporary identifier sent by the first peer device are received by the first relay device, the temporary identifier allocated by the first peer device to the first remote device is sent to the first remote device according to the identifier of the first remote device.

In some embodiments, the first remote device may receive a temporary identification assigned by the first peer device for the first remote device.

Under the condition that the first relay device can forward the data but does not analyze the data, the first relay device does not execute the function of analyzing and forwarding the content, and the first relay device plays a role in forwarding the data at the moment, so the first remote device receives the temporary identifier distributed by the first opposite terminal device.

In this process, the first remote device acts as the destination UE and the first peer device acts as the source UE.

It should be noted that, the first remote device receives the temporary identifier allocated by the first peer device, which may be the temporary identifier forwarded by the first relay device without performing the function of resolving the forwarding content.

In some embodiments, the first remote device may receive the temporary identifier allocated by the first remote device to the first remote device and the temporary identifier sent by the first relay device.

It should be noted that, before the first remote device does not receive the collision indication, in the case that the first relay device performs the function of resolving forwarding data, the first relay device may directly obtain the temporary identifier of the first remote device from the first peer device, so as to determine whether the temporary identifier of the first relay device collides with the first remote device; under the condition that the first relay device does not execute the function of analyzing and forwarding data, the first remote device receives the temporary identification forwarded to the first remote device by the first opposite terminal device through the first relay device, forwards the temporary identification to the first relay device, and the first relay device determines whether the temporary identification of the first relay device collides with the first remote device or not.

By means of the technical scheme, after the first far-end equipment forwards the conflict indication to the equipment in the side uplink, the first far-end equipment receives the temporary identification which is forwarded by the first relay equipment and is reassigned to the first far-end equipment, and/or receives the temporary identification which is reassigned to the first far-end equipment by the first opposite-end equipment, so that after the first far-end equipment conflicts with the temporary identification of the first relay equipment, the first far-end equipment can receive the temporary identification which is different from the temporary identification of the first relay equipment, and the temporary identification is distinguished from the temporary identification of the first relay equipment.

Fig. 10 is a flowchart of a temporary identity scheduling method according to an exemplary embodiment, and as shown in fig. 10, the temporary identity scheduling method is used in a first peer device, and includes the following steps.

In step S901, a collision instruction transmitted by a device on the reception side uplink is received.

The first peer device may receive the collision indication sent by the first remote device in the side uplink, or may receive the collision indication sent by the first relay device in the side uplink.

Under the condition that the first relay device does not execute the function of analyzing and forwarding data, the first opposite terminal device serves as a target UE and can receive a conflict indication sent by the first remote terminal device serving as a source UE.

For example, the first remote device obtains a collision indication from the first relay device, and the first remote device acts as a source UE, and forwards the collision indication to the first peer device acting as a destination UE through the first relay device.

When the first relay device performs the function of analyzing the forwarding data, the first peer device may serve as the destination UE and may receive the collision indication sent by the first relay device serving as the source UE.

For example, the first remote device may obtain the collision indication directly from the first relay device.

The first opposite terminal device is used as a party for distributing the identification to the first far-end device, and the conflict indication carries a temporary identification which the first relay device recommends to distribute to the first far-end device.

In step S902, a temporary identifier is reassigned to the corresponding device according to the collision indication.

The first peer device may reassign the identifier to the first remote device according to the proposed temporary identifier carried in the collision indication, or may itself regenerate the temporary identifier assigned to the first remote device.

The first opposite terminal equipment distributes temporary identifiers for the first far-end equipment and/or receives the temporary identifiers distributed by the first far-end equipment for the first opposite terminal equipment.

Through the technical scheme, when the first remote equipment collides with the temporary identifier of the first relay equipment, the first opposite terminal equipment can receive the collision indication sent by the equipment of the side uplink, and reallocate the temporary identifier for the first remote equipment according to the collision indication, so that the temporary identifier of the first remote equipment is different from the temporary identifier of the first relay equipment, and the first relay equipment can distinguish different temporary identifiers so as to forward the different temporary identifiers to different equipment.

Fig. 11 is a flowchart of a temporary identity scheduling method according to an exemplary embodiment, and as shown in fig. 11, the temporary identity scheduling method is used in a first peer device, and includes the following steps.

In step S110, the temporary identifier of the first remote device and/or the identifier of the first remote device is sent to a first relay device, where the first remote device communicates with a first peer device through the first relay device.
