Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a handover (HO) method, apparatus, device, and readable storage medium. Background Technology

[0002] In existing technologies, a terminal (such as a user equipment (UE)) establishes its own control plane connection and user plane connection with the core network, such as a Protocol Data Unit (PDU) session. When the UE moves between different cells, different base stations, or even different core network nodes, the network side transmits the UE's control plane connection, user plane connection, and transmission status between different network nodes to ensure that the UE's service transmission can be continuous, uninterrupted, and achieve lossless requirements as needed.

[0003] When two UEs (e.g., UE1 and UE2) transmit data, they each establish their own core network / access network control plane connection and user plane connection. For example, the Non-Access-Stratum (NAS) connection (core network control plane), Radio Resource Control (RRC) connection (access network control plane), PDU session (core network user plane), and Data Radio Bearer (DRB) / Quality of Service (QoS) flow (access network user plane) are all independent for the two UEs.

[0004] For example, if UE1 and UE2 are continuously transmitting a common service, and UE1 and / or UE2 experience a radio link failure (RLF), how to instruct UE1 and / or UE2 to perform a handover is an urgent problem to be solved. Summary of the Invention

It should be noted that in this application embodiment, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0044] See Figure 2 This application provides a switching method, which includes steps 201 and 202.

[0045] Step 201: The first device receives a handover command (HO CMD) from the network-side device. The handover command instructs the first device and one or more second devices to perform the handover process in a unified manner, or the handover command instructs the first device to perform the handover process.

[0046] For example, the first device is the one that generates the RLF.

[0047] Step 202: The first device executes the switching procedure according to the switching command;

[0048] The first device and the one or more second devices jointly transmit a first service, such as a streaming media service, in which the same video is played on the first device and one or more second devices, but it is not limited to this.

[0049] In this embodiment, the first device and one or more second devices can receive the handover command, so the first device and one or more second devices can uniformly execute the handover command according to the handover command; or, the network-side device only sends the handover command to the first device. In this case, the handover command instructs the first device to execute the handover command. After receiving the handover command, the first device can forward the handover command to the second device. In this case, the handover command instructs the second device to execute the handover process.

[0050] It should be noted that the first device can also be called the master device (e.g., master UE), and the second device can also be called the auxiliary device (e.g., secondary UE), or the first device can also be called the auxiliary device and the second device can also be called the master device.

[0051] In one embodiment of this application, when the handover command instructs the first device and one or more second devices to uniformly execute the handover process, the first device and the one or more second devices maintain a Radio Resource Control (RRC) connection with the network-side device, as described in Scenario 1 below.

[0052] In one embodiment of this application, when the handover command instructs the first device to perform a handover procedure, the first device maintains an RRC connection with the network-side device, and the one or more second devices maintain a data transmission link with the network-side device, as described in Scenario 2 below.

[0055] The first device reports eleventh information to the network-side device. The eleventh information includes: a first measurement result, or the eleventh information includes the first measurement result and a second measurement result, wherein the second measurement result is obtained by the second device performing the measurement and is acquired by the first device through interaction with the second device.

[0056] In embodiments of this application, the first device and the second device may interact with one or more of the following: measurement results and switching-related information.

[0057] In one embodiment of this application, the eleventh information further includes one or more of the following:

[0058] (1) Identification information of the second device, for example, the Serving-Temporary Mobile Subscriber Identity (S-TMSI) of the second device;

[0059] (2) Authorization or authentication information of the second device;

[0060] (3) Capability information of the second device;

[0061] (4) Other auxiliary information of the second device, such as power saving requirements, transmission requirements, etc.

[0062] In one embodiment of this application, after the first device receives a handover command from the network-side device, the method further includes:

[0063] The first device acquires the first information;

[0064] The first device stops transmitting the first service based on the first information;

[0065] Wherein, the first information instructs the first device and one or more second devices to stop transmitting the first service, or the first information instructs the first device to stop transmitting the first service.

[0066] In one embodiment of this application, when the first information instructs the first device to stop transmitting the first service, the method further includes:

[0067] The first device sends a second message to the second device, the second message instructing the second device to stop transmitting the first service;

[0068] or,

[0069] The first device sends a third message to the network-side device, the third message instructing the network-side device to stop sending data related to the first service to the second device.

[0070] In one embodiment of this application, the third information further includes one or more of the following:

[0071] (1) Identification information of the second device, for example, the S-TMSI of the second device;

[0072] (2) Authorization or authentication information of the second device;

[0073] (3) Capability information of the second device;

[0074] (4) Other auxiliary information of the second device, such as power saving requirements, transmission requirements, etc.

[0075] In one embodiment of this application, after the first device completes the handover process according to the handover command, the method further includes:

[0076] The first device resumes transmitting the first service.

[0077] For example, the first device and the second device can both resume receiving the first service from the network-side device, or the first device can resume receiving the first service from the network-side device, and then the first device can determine to resume the second device receiving the first service from the network-side device.

[0078] In one embodiment of this application, the first device resumes transmission of the first service, including:

[0079] The first device receives fourth information from a network-side device, the fourth information instructing the first device and one or more second devices to resume transmission of the first service, or the fourth information instructing the first device to resume transmission of the first service;

[0080] The first device resumes transmission of the first service based on the fourth information.

[0081] In one embodiment of this application, when the fourth information instructs the first device to resume transmitting the first service, the method further includes:

[0082] The first device sends a fifth message to the second device, the fifth message instructing the second device to resume the transmission of the first service;

[0083] or,

[0084] The first device sends a sixth message to the network-side device, the sixth message instructing the network-side device to resume sending data related to the first service to the second device.

[0085] In one embodiment of this application, the sixth information further includes one or more of the following:

[0086] (1) Identification information of the second device, for example, the S-TMSI of the second device;

[0087] (2) Authorization or authentication information of the second device;

[0088] (3) Capability information of the second device;

[0089] (4) Other auxiliary information of the second device, such as power saving requirements, transmission requirements, etc.

[0090] In one embodiment of this application, after the first device completes the handover process according to the handover command, the method further includes:

[0091] The first device activates the transmission of the first service.

[0092] In one embodiment of this application, the first device activates the transmission of the first service by one of the following:

[0093] (1) The first device receives seventh information from the network-side device, the seventh information instructing the first device and one or more second devices to activate the transmission of the first service;

[0094] (2) The first device receives eighth information from the network-side device, the eighth information instructing the first device to activate the transmission of the first service;

[0095] The first device sends a ninth message to the one or more second devices, the ninth message instructing the second devices to activate the transmission of the first service;

[0096] (3) The first device autonomously activates the transmission of the first service.

[0097] In one embodiment of this application, the switching command further includes information about the second device, which includes one or more of the following:

[0098] (1) Identification information of the second device, for example, the S-TMSI of the second device;

[0099] (2) Authorization or authentication information of the second device;

[0100] (3) Capability information of the second device;

[0101] (4) Other auxiliary information of the second device, such as power saving requirements, transmission requirements, etc.;

[0102] (5) The reconfiguration information of the second device, for example, the reconfiguration information is used to configure the second device to establish an RRC reconnection with the network side device;

[0103] (6) Tenth information, the tenth information indicating to activate the transmission of the first service.

[0104] It is understandable that since the handover command can include relevant information about the second device, after receiving the handover command, the first device can forward the handover command to the second device based on the relevant information of the second device. In this way, even if the network-side device does not directly send the handover command to the second device, the second device can still obtain the handover command through the first device, thereby enabling the second device to execute the handover process.

[0105] Taking the first device as UE, the second device as smartwatch, and the first service as streaming media service as an example, when the UE and smartwatch jointly transmit streaming media service, if the smartwatch experiences a UE failure, the UE can receive a handover command from the network-side device. This handover command instructs the UE or instructs the UE and smartwatch to uniformly execute the handover process, thus preventing the joint transmission of streaming media service by the UE and smartwatch from being interrupted or affecting the user experience.

[0106] In the embodiments of this application, when two or more devices are transmitting services together, the network side can instruct multiple devices to perform a unified handover, or instruct the device that experiences an RLF to perform a handover, so as to avoid the interruption of services transmitted by multiple devices and ensure the reliability of data transmission and user experience.

[0107] See Figure 3 This application provides a switching method, the specific steps of which include: step 301.

[0108] Step 301: The network-side device sends a handover command to the first device, wherein the handover command instructs the first device and one or more second devices to perform the handover process in a unified manner, or the handover command instructs the first device to perform the handover process.

[0109] The first device and the one or more second devices jointly transmit the first service.

[0110] For example, the first device is the one that generates the RLF.

[0111] In one embodiment of this application, when the handover command instructs the first device and one or more second devices to uniformly execute the handover process, the first device and the one or more second devices maintain an RRC connection with the network-side device.

[0112] In one embodiment of this application, when the handover command instructs the first device to perform a handover procedure, the first device maintains an RRC connection with the network-side device, and the one or more second devices maintain a data transmission link with the network-side device.

[0113] In one embodiment of this application, before the first device receives a handover command from the network-side device, the method further includes:

The eleventh information includes: a first measurement result, or the eleventh information includes a first measurement result and a second measurement result, wherein the first measurement result is obtained by the first device performing the measurement, and the second measurement result is obtained by the second device performing the measurement.
