[0033] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more comprehensive and complete and fully convey the concept of the example embodiments to those skilled in the art.

In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted.

That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0036] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0037] Figure 1 A schematic diagram showing an exemplary system architecture to which the technical solution of the embodiments of the present application can be applied.

[0038] like Figure 1 As shown, the system architecture may include a vehicle communication terminal 101 and two networks that share a common access network, wherein the core networks of the two networks are core network 1 and core network 2 respectively.

[0039] It should be understood that Figure 1 The number of vehicle communication terminals 101 and networks shown in FIG. 1 is merely illustrative. Any number of vehicle communication terminals 101 and networks may be provided as required.

[0040] In one embodiment of the present application, when the vehicle communication terminal 101 is within the coverage of the core network 1 (i.e., when interacting with the core network 1 through the access network), the core network entity in the core network 1 can communicate and negotiate with the core network entity in the core network 2 to obtain the communication resource pool allocated by the core network entity in the core network 2 to the vehicle communication terminal 101. Then the core network entity in the core network 1 can configure the communication resource pool allocated by the core network entity in the core network 2 to the vehicle communication terminal 101 through the access network, so that the vehicle communication terminal 101 uses the communication resources in the communication resource pool to communicate after moving to the coverage of the core network 2. It can be seen that this embodiment is based on Figure 1 In the system architecture shown, the vehicle communication terminal 101 can communicate in a resource pool mode.

[0041] In one embodiment of the present application, based on Figure 1 In the system architecture shown, the vehicle communication terminal 101 can also obtain communication resources based on the scheduling mode. Specifically, the access network can detect whether the access network entity connected to the vehicle communication terminal 101 has changed during the process of the vehicle communication terminal 101 switching from the coverage of the core network 1 to the coverage of the core network 2. If the access network entity connected to the vehicle communication terminal 101 has not changed, the vehicle communication terminal 101 continues to be scheduled for resources through the access network entity connected to the vehicle communication terminal 101; if the access network entity connected to the vehicle communication terminal 101 has changed, the source access network entity connected to the vehicle communication terminal 101 (the source access network entity, i.e., the access network entity connected to the vehicle communication terminal 101 when it is in the core network 1) sends the resource configuration information to the target access network entity connected to the vehicle communication terminal 101 (the target access network entity, i.e., the access network entity connected to the vehicle communication terminal 101 after switching to the core network 2), so that the target access network entity schedules resources for the vehicle communication terminal 101 according to the resource configuration information. It can be seen that this embodiment is based on Figure 1 In the system architecture shown, the vehicle communication terminal 101 can communicate in a scheduling mode.

[0042] It should be noted that Figure 1 The access network in the system architecture shown may be E-UTRA (Evolved Universal Terrestrial Radio Access), and the core network 1 and the core network 2 may be EPC (Evolved Packet Core) and 5GC (5G Core). For example, if the core network 1 is EPC, then the core network 2 is 5GC; if the core network 1 is 5GC, then the core network 2 is EPC.

[0043] Figure 2 A schematic diagram showing an exemplary system architecture to which the technical solution of the embodiments of the present application can be applied.

[0044] like Figure 2 As shown, the system architecture may include a vehicle communication terminal 201 , an access network 202 , an access network 203 , and a core network connected to the access network 202 and the access network 203 .

[0045] It should be understood that Figure 2 The number of vehicle communication terminals 201 and networks shown in FIG. 1 is merely illustrative. Any number of vehicle communication terminals 201 and networks may be provided as required.

[0046] It should be noted that Figure 2 The core network in the system architecture shown may be 5GC. Access network 202 and access network 203 may be E-UTRA and NR (New Radio). For example, if access network 202 is E-UTRA, then access network 203 is NR; if access network 202 is NR, then access network 203 is E-UTRA.

[0047] As Figure 2 A deformed system architecture, such as Figure 3 As shown, the core networks to which access network 202 and access network 203 are connected may also be different. For example, the core network to which access network 202 is connected is core network 1, and the core network to which access network 203 is connected is core network 2.

[0048] It should be noted that Figure 3The access network 202 and the access network 203 in the system architecture shown can be E-UTRA and NR. For example, if the access network 202 is E-UTRA, then the access network 203 is NR; if the access network 202 is NR, then the access network 203 is E-UTRA. If the access network 202 is E-UTRA and the access network 203 is NR, then the core network 1 can be EPC and the core network 2 can be 5GC; if the access network 202 is NR and the access network 203 is E-UTRA, then the core network 1 can be 5GC and the core network 2 can be EPC.

[0049] based on Figure 2 or Figure 3 In the system architecture shown, in one embodiment of the present application, when the vehicle communication terminal 201 is within the coverage of the access network 202, the access network 202 can determine whether cross-radio access technology resource control is allowed between the access network entity in the access network 202 and the access network entity in the access network 203. If cross-radio access technology resource control is allowed between the access network entity in the access network 202 and the access network entity in the access network 203, when the vehicle communication terminal 201 moves from the coverage of the access network 202 to the coverage of the access network 203, the access network entity in the access network 202 can continue to schedule resources for the vehicle communication terminal 201. It can be seen that this embodiment is based on Figure 2 or Figure 3 In the system architecture shown, the vehicle communication terminal 201 can communicate in a scheduling mode.

[0050] In one embodiment of the present application, based on Figure 2 or Figure 3 In the system architecture shown, the vehicle communication terminal 201 can also obtain communication resources based on the resource pool mode. Specifically, the vehicle communication terminal 201 can determine the supported network mode based on its own communication capabilities. If the vehicle communication terminal 201 only supports the network mode of the access network 202, then when the vehicle communication terminal 201 moves to the access network 203, it can continue to communicate through the communication resource pool allocated by the network entity in the access network 202; if the vehicle communication terminal 201 supports the network modes of the access network 202 and the access network 203, then when the vehicle communication terminal 201 moves to the access network 204, the resource configuration information of the access network 203 is maintained until the communication resources allocated by the network entity in the access network 204 are obtained. It can be seen that this embodiment is based on Figure 2 or Figure 3 In the system architecture shown, the vehicle communication terminal 201 can communicate in a resource pool mode.

[0051] The implementation details of the technical solution of the embodiment of the present application are described in detail below:

[0052] Figure 4 A flow chart of a communication method according to an embodiment of the present application is shown, and the communication method may be performed by a core network entity of a first network. Figure 4 As shown, the communication method at least includes steps S410 to S420, which are described in detail as follows:

[0053] In step S410, a core network entity of a first network performs communication negotiation with a core network entity of a second network to obtain a communication resource pool allocated by the core network entity of the second network to a terminal device in the first network, wherein the first network and the second network share an access network.

[0054] In one embodiment of the present application, the core network entity of the first network may communicate and negotiate with the core network entities of multiple second networks to obtain the communication resource pools allocated by the core network entities of each second network to the terminal device. For example, the core network entity of the first network may first determine all the second networks existing in the surrounding area, and then communicate and negotiate with the core network entities of each second network existing in the surrounding area to obtain the communication resource pools allocated by the core network entities of each second network to the terminal device.

[0055] In one embodiment of the present application, the core network entity of the first network can obtain the movement trajectory of the terminal device, and then predict the target second network to which the terminal device will move based on the movement trajectory of the terminal device, and then communicate and negotiate with the core network entity of the target second network to obtain the communication resource pool allocated by the core network entity of the target second network to the terminal device. For example, if there are second networks 1, 2, and 3 around the first network, assuming that the core network entity of the first network determines that the terminal device will move to the second network 2 based on the movement trajectory of the terminal device, then the second network 2 can be used as the target second network, and then the core network entity of the first network can communicate and negotiate with the core network entity of the target second network to obtain the communication resource pool allocated by the core network entity of the target second network to the terminal device. This method can reduce the number of communications between core network entities, thereby helping to improve communication efficiency.

[0056] Continue to refer to Figure 4 As shown, in step S420, the communication resource pool allocated by the core network entity of the second network is configured to the terminal device, so that the terminal device uses the communication resources in the communication resource pool to communicate after moving to the second network.

[0057] In one embodiment of the present application, after the terminal device moves to the second network, using the communication resources in the communication resource pool for communication may be selecting the communication resources for data transmission from the communication resource pool.

[0058] It should be noted that: Figure 4 The technical solution of the embodiment shown can be based on the aforementioned Figure 1 The system architecture shown, that is, the first network and the second network have the same access network but different core networks. For example, if the first network is a 4G network, then the core network of the first network is EPC, and the core network entity of the first network can be CF (Control Function), and the second network can be a 5G network, then the core network of the second network is 5GC, and the core network entity of the second network can be PCF (Policy Control Function). Similarly, if the first network is a 5G network, then the second network can be a 4G network. Specifically, Figure 4 The technical solution of the illustrated embodiment can be applied in a scenario where a terminal device moves from an EPC network adopting E-UTRA to a 5GC network adopting E-UTRA, or can also be applied in a scenario where a terminal device moves from a 5GC network adopting E-UTRA to an EPC network adopting E-UTRA, and the terminal device may be a V2X terminal.

[0059] Figure 5 A flow chart of a communication method according to an embodiment of the present application is shown. The communication method may be performed by an access network entity, such as an access network entity of a first network. Figure 5 As shown, the communication method at least includes steps S510 to S530, which are described in detail as follows:

[0060] In step S510, during the process of a terminal device switching from a first network to a second network, it is detected whether an access network entity to which the terminal device is connected changes, wherein the first network and the second network share an access network.

[0061] In one embodiment of the present application, if the first network and the second network share an access network, when the terminal device switches from the first network to the second network, the access network entity to which the terminal device is connected may be the same access network entity or different access network entities.

[0062] In step S520, if the access network entity to which the terminal device is connected has not changed, resources for the terminal device continue to be scheduled through the access network entity.

[0063] In one embodiment of the present application, if the access network entity to which the terminal device is connected does not change during the process of switching from a first network to a second network, the terminal device can be continuously scheduled through the access network entity, that is, although the core network may change, the terminal device may still be connected to an access network entity (such as a base station) of the same access network.

[0064] In step S530, if the access network entity to which the terminal device is connected changes, the source access network entity to which the terminal device is connected sends resource configuration information to the target access network entity to which the terminal device is connected, so that the target access network entity schedules resources for the terminal device according to the resource configuration information.

[0065] In one embodiment of the present application, if the access network entity to which the terminal device is connected changes during the process of switching from the first network to the second network, then since the first network and the second network share the access network, the first network and the second network both support the same wireless resources, and then the source access network entity can send the resource configuration information to the target access network entity, so that the target access network entity can schedule resources for the terminal device according to the resource configuration information. For example, if the access network shared by the first network and the second network is E-UTRA, then the first network and the second network both support E-UTRA radio resources, and then the source access network entity (such as a base station) can pass the PC5 resource configuration information as a switching context to the target access network entity. If the target access network entity determines that continuous resource scheduling can be performed, it can notify the terminal device and then schedule resources for the terminal device.

[0066] It should be noted that: Figure 5 The technical solution of the embodiment shown can be based on the aforementioned Figure 1 The system architecture shown, that is, the first network and the second network have the same access network but different core networks. For example, if the first network is a 4G network, then the second network can be a 5G network; if the first network is a 5G network, then the second network can be a 4G network. The access networks of the first network and the second network can be E-UTRA, and the access network entity of the first network and the access network entity of the second network can both be base stations. Specifically, Figure 5 The technical solution of the illustrated embodiment can be applied in a scenario where a terminal device moves from an EPC network adopting E-UTRA to a 5GC network adopting E-UTRA, or can also be applied in a scenario where a terminal device moves from a 5GC network adopting E-UTRA to an EPC network adopting E-UTRA, and the terminal device may be a V2X terminal.

[0067] Figure 6 A flow chart of a communication method according to an embodiment of the present application is shown. The communication method may be performed by an access network entity, such as an access network entity of a first network. Figure 6 As shown, the communication method at least includes steps S610 to S620, which are described in detail as follows:

[0068] In step S610, it is determined whether cross-radio access technology resource control is allowed between an access network entity of a third network and an access network entity of a fourth network, wherein the access networks of the third network and the fourth network are different.

[0069] In one embodiment of the present application, if the access networks of the third network and the fourth network are different, the core networks of the third network and the fourth network may be the same or different. For example, the third network and the fourth network may be an EPC network using E-UTRA and a 5GC network using NR, or may be a 5GC network using E-UTRA and a 5GC network using NR.

[0070] In one embodiment of the present application, the access network entity of the third network may communicate and negotiate with the access network entity of the fourth network to determine whether cross-radio access technology resource control is allowed between the access network entity of the third network and the access network entity of the fourth network.

[0071] In one embodiment of the present application, the core network entity of the third network may communicate and negotiate with the core network entity of the fourth network to determine whether cross-radio access technology resource control is allowed between the access network entity of the third network and the access network entity of the fourth network.

[0072] In step S620, if resource control across wireless access technologies is allowed between the access network entity of the third network and the access network entity of the fourth network, when the terminal device moves from the third network to the fourth network, resources are scheduled for the terminal device through the access network entity of the third network.

[0073] In one embodiment of the present application, before the access network entity of the third network performs resource scheduling on the terminal device, the communication resources configured by the access network entity of the fourth network may also be obtained. For example, the access network entity of the third network and the access network entity of the fourth network obtain the communication resources configured by the access network entity of the fourth network through negotiation in advance. Then, when the access network entity of the third network performs resource scheduling on the terminal device, it may schedule the terminal device to communicate using the communication resources configured by the access network entity of the fourth network.

[0074] In one embodiment of the present application, after resources are scheduled for the terminal device through the access network entity of the third network, a switching instruction can also be sent to the access network entity of the fourth network so that after the terminal device accesses the access network entity of the fourth network, the access network entity of the fourth network schedules resources for the terminal device.

[0075] In one embodiment of the present application, if resource control across wireless access technologies cannot be performed between an access network entity of a third network and an access network entity of a fourth network, then when a terminal device moves from the third network to a fourth network, the terminal device can be controlled to release communication resources of the third network so that the access network entity of the fourth network can reallocate communication resources to the terminal device.

[0076] It should be noted that: Figure 6 The technical solution of the embodiment shown can be based on the aforementioned Figure 2 or Figure 3 The system architecture shown, that is, the third network and the fourth network have the same access network, but the core network can be the same or different. Specifically, Figure 6 The technical solution of the illustrated embodiment can be applied in a scenario where a terminal device moves from an EPC network adopting E-UTRA to a 5GC network adopting NR, or can also be applied in a scenario where a terminal device moves from a 5GC network adopting E-UTRA to a 5GC network adopting NR, or can also be applied in a scenario where a terminal device moves from a 5GC network adopting NR to an EPC network adopting E-UTRA, or can also be applied in a scenario where a terminal device moves from a 5GC network adopting NR to a 5GC network adopting E-UTRA, and the terminal device may be a V2X terminal.

[0077] Figure 7 A flow chart of a communication method according to an embodiment of the present application is shown, and the communication method can be executed by a terminal device. Figure 7 As shown, the communication method at least includes steps S710 to S730, which are described in detail as follows:
