[0024] Hereinafter, exemplary embodiments will be described more completely with reference to the accompanying drawings. However, exemplary embodiments can be implemented in various forms and should not be understood as being limited to the examples described in this specification. Rather, by providing these embodiments, the present disclosure will be more thorough and complete, and the concept of the exemplary embodiments can be fully conveyed to those skilled in the art.

[0025] Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, a number of specific details are provided to provide a thorough understanding of the embodiments of the present disclosure. However, one skilled in the art will recognize that the technical solutions of the present disclosure may be implemented without one or more of the details, or may employ other methods, groups, devices, steps, etc. In other cases, well-known methods, devices, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the present disclosure.

[0026] The block diagrams shown in the drawings are merely functional entities which do not necessarily correspond to physically separate entities, i.e. these functional entities may be realised in software, or in one or more hardware modules or integrated circuits, or in different network and / or processor and / or microcontroller devices.

[0027] The illustrated flow charts are merely exemplary and do not necessarily include all content and operations / steps or require execution in the order described (e.g., some operations / steps may be separated, combined, or partially combined, such that the order in which they are actually executed may vary depending on circumstances).

[0028] FIG. 1 is a schematic diagram of a system architecture that can adopt the technical proposals provided by the embodiments of this specification.

[0029] As shown in FIG. 1, the system architecture may include a vehicle communication terminal 101 and two networks sharing an access network, and the core networks of these two networks are core network 1 and core network 2, respectively.

[0030] It should be understood that the number of vehicular communication terminals 101 and networks shown in Figure 1 is merely exemplary. In practical applications, the system architecture may include any number of vehicular communication terminals 101 and networks according to implementation needs.

[0031] In one aspect of the embodiment of the present disclosure, when the vehicular communication terminal 101 is within the coverage area of ​​the core network 1, i.e., when interacting with the core network 1 through an access network, a core network entity in the core network 1 can perform communication negotiation with a core network entity in the core network 2 to obtain a communication resource pool allocated to the vehicular communication terminal 101 by the core network entity in the core network 2. Then, the core network entity in the core network 1 can allocate the communication resource pool allocated by the core network entity in the core network 2 to the vehicular communication terminal 101 through the access network, and can communicate using the communication resources in the communication resource pool after the vehicular communication terminal 101 moves into the coverage area of ​​the core network 2. As a result, the vehicular communication terminal 101 can communicate in a resource pool mode based on the system architecture shown in FIG. 1.

[0032] In one aspect of the embodiment of the present disclosure, based on the system architecture shown in Fig. 1, the vehicular communication terminal 101 can also obtain communication resources based on a scheduling mode. Specifically, the access network can detect whether an entity of the access network to which the vehicular communication terminal 101 is connected has changed in the process of the vehicular communication terminal 101 moving from the coverage area of ​​the core network 1 to the coverage area of ​​the core network 2. If the access network entity to which the vehicular communication terminal 101 is connected has not changed, the access network entity to which the vehicular communication terminal 101 is connected continues to schedule communication resources for the vehicular communication terminal 101. On the other hand, when the access network entity to which the vehicular communication terminal 101 is connected changes, the source access network entity to which the vehicular communication terminal 101 is connected (the source access network entity transmits resource allocation information to the target access network entity to which the vehicular communication terminal 101 is connected (the target access network entity is the target access network entity to which the vehicular communication terminal 101 is connected after the vehicular communication terminal 101 moves into the coverage area of ​​the core network 2), and the target access network entity schedules communication resources for the vehicular communication terminal 101 based on the resource allocation information. This allows the vehicular communication terminal 101 to communicate in a scheduling mode based on the system architecture shown in FIG. 1.

[0033] In addition, the access network in the system architecture shown in FIG. 1 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, when the core network 1 is EPC, the core network 2 may be 5GC. On the other hand, when the core network 1 is 5GC, the core network 2 may be EPC.

[0034] FIG. 2 is a schematic diagram of another exemplary system architecture that can employ the technical solutions provided by the embodiments herein.

[0035] As shown in FIG. 2, 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.

[0036] It should be understood that the number of vehicle communication terminals 201 and networks shown in Figure 2 is merely exemplary. In practical applications, the system architecture may include any number of vehicle communication terminals 201 and networks according to implementation needs.

[0037] In addition, the core network in the system architecture shown in Figure 2 may be 5GC. The access network 202 and the access network 203 may be E-UTRA and NR (New Radio). For example, when the access network 202 is E-UTRA, the access network 203 may be NR. On the other hand, when the access network 202 is NR, the access network 203 may be E-UTRA.

[0038] As one of the modified system architectures of Fig. 2, the core networks connected to the access network 202 and the access network 203 do not have to be the same as each other, as shown in Fig. 3. For example, the core network connected to the access network 202 is the core network 1, and the core network connected to the access network 203 is the core network 2.

[0039] In addition, the access network 202 and the access network 203 in the system architecture shown in FIG. 3 may be E-UTRA and NR. For example, when the access network 202 is E-UTRA, the access network 203 may be NR. On the other hand, when the access network 202 is NR, the access network 203 may be E-UTRA. When the access network 202 is E-UTRA and the access network 203 is NR, the core network 1 may be EPC and the core network 2 may be 5GC. On the other hand, when the access network 202 is NR and the access network 203 is E-UTRA, the core network 1 may be 5GC and the core network 2 may be EPC.

[0040] Based on the system architecture shown in FIG. 2 or FIG. 3, in one aspect of the embodiment of the present disclosure, when the vehicular communication terminal 201 is within the coverage area of ​​the access network 202, the access network 202 can determine whether or not communication resource control based on the wireless switching access technology is permitted between an access network entity in the access network 202 and an access network entity in the access network 203. If communication resource control based on the wireless switching access technology is permitted between the access network entity in the access network 202 and the access network entity in the access network 203, when the vehicular communication terminal 201 moves from the coverage area of ​​the access network 202 to the coverage area of ​​the access network 203, the access network entity in the access network 202 continues to perform communication resource scheduling for the vehicular communication terminal 201. As a result, based on the system architecture shown in FIG. 2 or FIG. 3, the vehicular communication terminal 201 can also communicate in a scheduling mode.

[0041] In one aspect of the embodiment of the present disclosure, based on the system architecture shown in FIG. 2 or FIG. 3, the vehicular communication terminal 201 may acquire communication resources based on the resource pool mode. Specifically, the vehicular communication terminal 201 may identify a supported network mode based on its own communication capability, and when the vehicular communication terminal 201 supports only the network mode of the access network 202, the vehicular communication terminal 201 continues to communicate in a communication resource pool allocated by a network entity in the access network 202 when the vehicular communication terminal 201 moves into the coverage area of ​​the access network 203. When the vehicular communication terminal 201 supports the network modes of the access network 202 and the access network 203 simultaneously, the vehicular communication terminal 201 holds resource allocation information of the access network 202 until the communication resources allocated by the network entity in the access network 203 are acquired after the vehicular communication terminal 201 moves into the coverage area of ​​the access network 203. As a result, based on the system architecture shown in FIG. 2 or FIG. 3, the vehicular communication terminal 201 can also communicate in a resource pool mode.

[0042] The implementation details of the technical solutions of the embodiments of the present disclosure are described in detail below.

[0043] 4 shows a flowchart of a communication method performed by a core network entity of a first network provided in one aspect of an embodiment of the present disclosure. Referring to FIG. 4, the communication method includes at least steps S410 to S420, and is described in detail as follows:

[0044] In step S410, communication negotiation is performed with a core network entity of a second network, and the core network entity of the second network obtains a communication resource pool allocated to a terminal device in the first network, and the first network and the second network share an access network.

[0045] In one aspect of the embodiment of the present disclosure, a core network entity of a first network can perform communication negotiation with core network entities of multiple second networks to obtain a communication resource pool allocated to a terminal device in the first network by the core network entities of the second networks. For example, the core network entity of the first network can identify all second networks existing in the vicinity, and then perform communication negotiation with core network entities of each of the second networks existing in the vicinity to obtain a communication resource pool allocated to a terminal device by the core network entities of each of the second networks.

[0046] In one aspect of the embodiment of the present disclosure, the core network entity of the first network can obtain the movement trajectory of the terminal device. Then, based on the movement trajectory of the terminal device, a network corresponding to the location range in which the terminal device should move is predicted as a target second network, and communication negotiation is performed with the core network entity of the target second network, and the core network entity of the target second network obtains the communication resource pool allocated to the terminal device. For example, assuming that the second network 1, the second network 2, and the second network 3 exist in the vicinity of the first network, when the core network entity of the first network determines that the location range in which the terminal device should move corresponds to the second network 2 based on the movement trajectory of the terminal device, the second network 2 is set as the target second network, and the core network entity of the first network can obtain the communication resource pool allocated to the terminal device by performing communication negotiation with the core network entity of the second network 2. This can reduce the number of communications between the core network entities, which is advantageous for improving communication efficiency.

[0047] Continuing to refer to FIG. 4, in step S420, the communications resource pool is configured to the terminal device, such that the terminal device uses communications resources in the communications resource pool to communicate after moving to the second network.

[0048] In one aspect of an embodiment of the present invention, after a terminal device moves to a second network, it can communicate using communication resources in a communication resource pool and select communication resources for data transmission from the communication resource pool.

[0049] It should be noted that the technical solution of the embodiment shown in FIG. 4 can be realized based on the system architecture shown in FIG. 1, that is, the first network and the second network may have the same access network but different core networks. For example, when the first network is a 4G network, the core network of the first network may be an EPC, and the core network entity of the first network may be a CF (Control Function) entity; when the second network is a 5G network, the core network entity of the second network may be a 5GC, and the core network entity of the second network may be a PCF (Policy Control Function). Similarly, when the first network is a 5G network, the second network may be a 4G network. Specifically, the technical solution of the embodiment shown in FIG. 4 can be applied to a scene in which a terminal device moves from an EPC network adopting E-UTRA to a 5GC network adopting E-UTRA, or a scene in which 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.

[0050] 5 shows a flowchart of another communication method provided by an embodiment of the present disclosure, which may be performed by an access network entity, such as an access network entity of a first network. Referring to FIG. 5, the communication method includes at least steps S510 to S530, and is described in detail as follows:

[0051] In step S510, in the process of the terminal device switching from a first network to a second network, it is detected whether the access network entity to which the terminal device is connected has changed, and the first network and the second network share an access network.

[0052] In one aspect of an embodiment of the present disclosure, when a first network shares an access network with a second network, while 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 a different access network entity.

[0053] In step S520, if the access network entity to which the terminal device is connected has not changed, the access network entity continues to perform communication resource scheduling for the terminal device.

[0054] In an embodiment of the present disclosure, if the access network entity to which the terminal device is connected does not change while the terminal device switches from a first network to a second network, the access network entity can perform continuous communication scheduling for the terminal device, i.e., the core network may change, but the terminal device may still connect to the same access network entity, such as a base station.

[0055] 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 a target access network entity to which the terminal device is connected, and the target access network entity performs communication resource scheduling for the terminal device based on the resource configuration information.

[0056] The source access network entity here is the access network entity to which the terminal device is connected in the first network, and the target access network entity is the access network entity to which the terminal device is connected after switching from the first network to the second network.

[0057] In one aspect of the embodiment of the present disclosure, when 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, the first network shares an access network with the second network, so that both the first network and the second network support the same radio resources, and the target access network entity may transmit resource configuration information from the source access network entity to the target access network entity, so that the target access network entity performs communication resource scheduling for the terminal device based on the resource configuration information. For example, when the access network shared by the first network with the second network is E-UTRA, both the first network and the second network support E-UTRA radio resources, and the source access network entity, such as a base station, may pass the PC5 resource configuration information to the target access network entity as a switching context. If the target access network entity determines that continuous resource scheduling is possible, it may notify the terminal device, and may perform communication resource scheduling for the terminal device based on the PC5 resource configuration information.

[0058] It should be noted that the technical solution of the embodiment shown in FIG. 5 can be realized based on the system architecture shown in FIG. 1, that is, the first network and the second network may have the same access network but different core networks. For example, if the first network is a 4G network, the second network may be a 5G network; if the first network is a 5G network, the second network may be a 4G network. The access networks of the first network and the second network may be E-UTRA, and the access network entity of the first network and the access network entity of the second network may both be base stations. Specifically, the technical solution of the embodiment shown in FIG. 5 can be applied to a scene in which a terminal device moves from an EPC network adopting E-UTRA to a 5GC network adopting E-UTRA, or a scene in which 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] 6 shows a flowchart of another communication method provided by an embodiment of the present disclosure, which may be performed by an access network entity, such as an access network entity of a third network. Referring to FIG. 6, the communication method includes at least steps S610 to S620, and is described in detail as follows:

[0060] In step S610, determine whether communication resource control based on wireless switching access technology is allowed between an access network entity of a third network and an access network entity of the fourth network, and the access network of the third network is different from the access network of the fourth network.

[0061] In one aspect of the embodiment of the present disclosure, when 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 adopting E-UTRA and a 5GC network adopting NR, respectively, or may be a 5GC network adopting E-UTRA and a 5GC network adopting NR, respectively.

[0062] In one aspect of an embodiment of the present disclosure, an access network entity of a third network and an access network entity of a fourth network can perform communication negotiation to determine whether communication resource control based on wireless switching access technology is permitted between the access network entity of the third network and the access network entity of the fourth network.

[0063] In one aspect of an embodiment of the present disclosure, a core network entity of the third network and a core network entity of the fourth network may perform communication negotiation to determine whether communication resource control based on wireless switching access technology is permitted between an access network entity of the third network and an access network entity of the fourth network.

[0064] In step S620, if communication resource control based on wireless switching access technology is permitted between the access network entity of the third network and the access network entity of the fourth network, the access network entity of the third network performs communication resource scheduling for the terminal device while the terminal device is moving from the third network to the fourth network.

[0065] In one aspect of the embodiment of the present disclosure, before scheduling communication resources for a terminal device in an access network entity of a third network, the access network entity of the third network may acquire communication resources arranged by an access network entity of a fourth network. For example, the access network entity of the third network may negotiate with the access network entity of the fourth network in advance to acquire communication resources arranged by the access network entity of the fourth network. Furthermore, when scheduling communication resources for a terminal device in the access network entity of the third network, the access network entity of the third network may schedule the terminal device to communicate using the communication resources arranged by the access network entity of the fourth network.
