Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method and apparatus for transmitting configuration information. Background Technology

[0002] In a DC (Dual Connectivity) scenario, a terminal device can access two cell groups: the MCG (Master Cell group) and the SCG (Secondary Cell group). If only the MCG or SCG accessed by the terminal device is changed, only signaling interaction between the source node and the target node is involved. However, if both the MCG and SCG are changed simultaneously, such as performing condition-triggered mobility management or selective activation of cell groups on both the MCG and SCG at the same time, the T-MN (target Master Node) needs to establish a connection with the SCG to achieve mobility for both the MCG and SCG simultaneously. Summary of the Invention

[0003] A first aspect of this disclosure provides a configuration information transmission method applied to a first communication node. The method includes: sending a first request message for mobility management to a second communication node; and / or receiving a first feedback message for mobility management from the second communication node; wherein at least one target communication object indicated by the first request message is at least one of a recommended configuration target communication object and a non-recommended configuration target communication object; and at least one target communication object indicated by the first feedback message is at least one of a configured target communication object and a rejected configuration target communication object.

[0004] In this technical solution, by sending a request message from the first communication node to the second communication node, the first communication node is instructed to recommend configuring at least one target communication object and / or to not recommend configuring at least one target communication object. This allows the first communication node to participate in the selection of target communication objects, ensuring that the selected target communication objects conform to the mobility management requirements initiated by the first communication node. Alternatively, by sending a feedback message from the second communication node to the first communication node, the second communication node is instructed to configure target communication objects and / or reject configure target communication objects. This allows the first communication node to be promptly informed of the configured target communication objects and / or rejected target communication objects, thereby keeping mobility management within the control of the first communication node.

[0041] To facilitate understanding, the terminology used in this disclosure will be introduced first.

[0042] 1. MR-DC (Multi-Radio Dual Connectivity)

[0043] MR-DC is a generalized Intra-E-UTRA (Intra-Evolved-UMTS (Universal Mobile Telecommunications System) Terrestrial Radio Access) dual connectivity. Terminal equipment can utilize radio resources provided by two different schedulers located on two different NG-RAN (5G Radio Access Network) nodes via a non-ideal backhaul connection. One node provides NR access, and the other provides either E-UTRA or NR access. One node acts as the MN (Master Node), and the other as the SN (Secondary Node). The MN and SN are connected via a network interface, and at least one MN is connected to the core network.

[0044] 2. MR-DC using EPC (Evolved Packet Core)

[0045] E-UTRAN (Evolved-UMTS Terrestrial Radio Access Network) supports MR-DC through E-UTRA-NR DC (Evolved-UMTS Terrestrial Radio Access-New RadioDual Connectivity, or EN-DC). In this setup, the terminal equipment connects to an eNB (evolved NodeB, a 4G base station) acting as the MN and an en-gNB (en-next generation NodeB, a modified 5G base station) acting as the SN.

[0046] As an example, the EN-DC architecture diagram can be as follows: Figure 1 As shown, the eNB is connected to the EPC via the S1 interface, and the eNB is connected to the en-gNB via the X2 interface; the en-gNB is connected to the EPC via the S1-U interface, and the en-gNB is connected to other en-gNBs via the X2-U interface. Figure 1In this context, MME stands for Mobility Management Entity, and S-GW stands for Serving Gateway.

[0047] 3. MR-DC using 5GC (5G core, 5G core network)

[0048] (1) E-UTRA-NR Dual Connectivity NGEN-DC (NG-RAN E-UTRA-NR Dual Connectivity, UMTS Terrestrial Radio Access-New Radio Dual Connectivity for 5G Radio Access Network Evolution)

[0049] NG-RAN supports NGEN-DC, where terminal equipment connects to an ng-eNB (next-generation evolved NodeB) acting as the MN and a gNB (next-generation NodeB) acting as the SN. The ng-eNB connects to the 5GC, and the gNB connects to the ng-eNB via the Xn interface.

[0050] (2) NR-E-UTRA Dual Connectivity (NE-DC)

[0051] NG-RAN supports NE-DC, where the end equipment connects to a gNB that acts as the MN and an ng-eNB that acts as the SN. The gNB connects to the 5GC, and the ng-eNB connects to the gNB via the Xn interface.

[0052] (3)NR-NR Dual Connectivity (NR-DC for short)

[0053] NG-RAN supports NR-DC, where an end device connects to a gNB that acts as both the MN and the SN. The primary gNB connects to the 5GC via the NG interface, the secondary gNB connects to the 5GC via the NG-U interface, and the gNBs are connected to each other via the Xn interface. Furthermore, NR-DC can also be used for end devices to access a single gNB. In this case, the gNB accessed by the end device can simultaneously act as both the MN and SN, and be configured with both MCG and SCG.

[0054] As an example, the NR-DC architecture can be as follows: Figure 2 As shown.

[0055] 4. PCell (Primary Cell), SCell (Secondary Cell), and PSCell (Primary Secondary Cell)

[0056] In dual-connectivity scenarios, terminal devices can access two cell groups: the MCG (Master Cell Group) and the SCG (Secondary Cell Group). The MCG and SCG correspond to the MN and SN on the network device side, respectively. An MCG may contain multiple cells; the cell used to initiate initial access is called the PCell, which, as the name suggests, is the most "primary" cell in the MCG. For example... Figure 3 As shown, in addition to PCells, MCGs can also include SCells, where PCells and SCells are combined via CA (Carrier Aggregation). SCGs can include PSCells (Primary Secondary Cells) and SCells. Since much signaling is transmitted only on PCells and PSCells, for ease of description, the protocol also defines a concept: SpCell (Special Cell), such as... Figure 3 As shown, PCell and PSCell can be collectively referred to as SpCell.

[0057] In other words, an MCG includes SpCell (PCell) and one or more SCells. An MCG refers to a group of serving cells associated with an MN in an MR-DC. An MN is a radio access node in an MR-DC that provides control plane connectivity to the core network. An MN can be a primary eNB (in an EN-DC), a primary ng-eNB (in an NGEN-DC), or a primary gNB (in NR-DC and NE-DC).

[0058] An SCG comprises SpCell (PSCell) and one or more SCells. In MR-DC, an SCG refers to a group of serving cells associated with a SN. The SN, in MR-DC, is a radio access node that provides additional resources to terminal devices, even without a control plane connection to the core network. The SN can be an en-gNB (in EN-DC), a secondary ng-eNB (in NE-DC), or a secondary gNB (in NR-DC and NGEN-DC).

[0059] 5. Selective activation of cell groups

[0060] For CHO (Conditional Handover) in Rel-16 and CPC (Conditional PSCell Change) or CPA (Conditional PSCell Addition) in Rel-17, terminal devices configured with CHO / CPC / CPA must release the CHO / CPC / CPA configuration when completing random access to the target PCell / PSCell. If the network device does not reconfigure and reinitialize CHO / CPC / CPA, the terminal device will be unable to continue executing CHO / CPC / CPA. This will increase the latency of handover or SCG change and increase signaling overhead, especially in scenarios where CG (Cell Group) changes are frequent in the FR2 high-frequency band.

[0061] Therefore, in the mobility enhancement project, selective activation of cell groups in MR-DC was proposed. Selective activation of cell groups allows subsequent CHO / CPC / CPA to still be executed after the CG changes, without requiring network equipment to reconfigure or reinitialize CHO / CPC / CPA, thereby reducing signaling overhead and the interruption time due to CG changes.

[0062] 6. Condition-triggered mobility management

[0063] In Release 16 / R17, condition-triggered mobility management (CTLM) was introduced. Terminal devices implement CTLM based on conditions configured by the network device and associated candidate cells. When the conditions are met, the terminal device triggers mobility management and accesses its associated candidate cell. The conditions configured by the network device can be specific events based on measurement results, location, or time. The associated candidate cells can be primary and secondary candidate cells, corresponding to CHO and CPC / CPA in CTLM, respectively.

[0064] However, currently, simultaneous configuration of CHO and CPA / CPC is not supported. To improve robustness and reduce the impact on terminal device throughput, the mobility enhancement project proposes to study a scheme combining CHO and CPC / CPA, in which CHO includes the target MCG and candidate SCGs for CPA.

[0065] To better understand the configuration information transmission method disclosed in this embodiment, the communication system to which this embodiment applies is described below.

[0066] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0067] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. Unless otherwise indicated, the same numerals in different drawings denote the same or similar elements in the following description relating to the drawings. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0068] Please see Figure 4 , Figure 4 This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure. The communication system may include, but is not limited to, a network device and a terminal device. Figure 4 The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure. In actual applications, two or more network devices and two or more terminal devices may be included. Figure 4 The communication system shown is only an example that includes one network device 401 and one terminal device 402.

[0069] It should be noted that the technical solutions of this disclosure can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, 5th Generation (5G) mobile communication systems, 5G New Radio (NR) systems, or other future new mobile communication systems.

[0070] The network device 401 in this embodiment is a network-side entity used for transmitting or receiving signals. For example, the network device 401 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This disclosure does not limit the specific technology or device form used in the network device. The network device provided in this disclosure can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure allows the protocol layer of a network device, such as a base station, to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0071] In this disclosure, the terminal device 402 is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. Terminal devices can be communication-enabled vehicles, smart cars, mobile phones, wearable devices, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminal devices in industrial control, wireless terminal devices in self-driving, wireless terminal devices in remote medical surgery, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, wireless terminal devices in smart homes, and so on. This disclosure does not limit the specific technology or device form used in the terminal device.

[0072] In the aforementioned communication system, under dual-connectivity scenarios, if only the MCG or SCG accessed by the terminal device is modified, only signaling interaction between the source node and the target node will be involved. However, if both the MCG and SCG are modified simultaneously, such as performing condition-triggered mobility management or selective activation of cell groups on both the MCG and SCG at the same time, then the T-MN needs to establish a connection with the SCG in order to achieve mobility for both the MCG and SCG simultaneously.

[0073] However, in the above method, the source node cannot control the selection of the T-SN (target Secondary Node) and can only leave it entirely to the T-MN to decide which T-SN to choose. The source node cannot participate in the selection of the T-SN, which contradicts the requirement for simultaneous changes to the MCG and SCG initiated by the source node. Furthermore, since the T-SN does not directly send feedback messages to the source node, the source node cannot know the T-SN configured for the SCG, thus making SCG mobility management outside the source node's control.

[0074] To address the aforementioned issues, this disclosure provides a method and apparatus for transmitting configuration information.

[0075] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.

[0076] The configuration information transmission method and apparatus provided in this disclosure will now be described in detail with reference to the accompanying drawings.

[0077] Please see Figure 5 , Figure 5 This is a flowchart illustrating a configuration information transmission method provided in an embodiment of this disclosure. This configuration information transmission method can be executed by a first communication node, which can be... Figure 4 The source node on the network device side of the communication system shown can be, for example, the first communication node, an S-MN (source master node) or an S-SN (source secondary node), and this disclosure does not limit it.

[0078] S-MN refers to the primary node currently serving the terminal device when configuring a DC for the terminal device, and S-SN refers to the secondary node currently serving the terminal device when configuring a DC for the terminal device.

[0079] The configuration information transmission method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in related technologies.

[0080] like Figure 5 As shown, the configuration information transmission method may include, but is not limited to, the following steps:

[0081] Step 501: Send a first request message for mobility management to the second communication node, and / or receive a first feedback message for mobility management from the second communication node.

[0082] Wherein, the first request message indicates at least one target communication object, which is at least one of a recommended configuration target communication object and a non-recommended configuration target communication object; the first feedback message indicates at least one target communication object, which is at least one of a configured target communication object and a rejected configuration target communication object.

[0083] In this embodiment of the disclosure, the second communication node can be the target node, such as T-MN or T-SN, and this disclosure does not limit it.

[0084] The T-MN can be the master node corresponding to a candidate target cell (referred to as the target cell in this disclosure) or a candidate target cell group (referred to as the target cell group in this disclosure) associated with the terminal device. The target cell can include a target PCell and / or a target PSCell and / or a target SCell, and the target cell group can include a target MCG and / or a target SCG. For example, the T-MN can be the master node corresponding to the target MCG.

[0085] Among them, T-SN can be the auxiliary node corresponding to the target cell or target cell group. For example, T-SN can be the auxiliary node corresponding to the target SCG.

[0086] In this embodiment of the disclosure, the target communication object may include at least one of the following: a target node; a target cell; a target cell group. The target node may include a T-MN and / or a T-SN.

[0087] As one possible implementation, the first communication node may send a first request message for mobility management to the second communication node, wherein the first request message is used to indicate at least one target communication object, and the at least one target communication object may include a target communication object with recommended configuration and / or a target communication object with not recommended configuration.

[0088] In other words, in this disclosure, a first communication node can send a request message to a second communication node to indicate at least one target communication object that the first communication node recommends to configure, and / or to indicate at least one target communication object that the first communication node does not recommend to configure.

[0089] As an example, the first communication node may send a request message to the second communication node carrying a target communication object with recommended configuration and / or a target communication object with unrecommended configuration. After receiving the request message, the second communication node may send a feedback message to the first communication node without indicating the configured target communication object and / or rejecting the configured target communication object.

[0090] As another possible implementation, the first communication node may receive a first feedback message for mobility management sent by the second communication node, wherein the first feedback message is used to indicate at least one target communication object, wherein the at least one target communication object includes a configured target communication object and / or a rejected target communication object.

[0091] In other words, in this disclosure, the second communication node can send a feedback message to the first communication node to indicate the target communication object that has been configured and / or the target communication object that has been rejected.

[0092] As an example, the first communication node may send a request message to the second communication node that does not carry the recommended configuration of the target communication object and / or does not recommend the configuration of the target communication object. After receiving the request message, the second communication node may send a feedback message to the first communication node indicating the configured target communication object and / or rejecting the configuration of the target communication object.

[0093] As another possible implementation, the first communication node can send a first request message for mobility management to the second communication node. Correspondingly, after receiving the first request message sent by the first communication node, the second communication node can respond to the first request message by sending a first feedback message to the first communication node, so that the first communication node can receive the first feedback message sent by the second communication node.

[0094] As an example, the first communication node may send a request message to the second communication node carrying a target communication object with recommended configuration and / or a target communication object with unrecommended configuration. After receiving the request message, the second communication node may send a feedback message to the first communication node indicating the configured target communication object and / or the unconfigured target communication object.

[0095] The configuration information transmission method of this disclosure embodiment involves a first communication node sending a first request message for mobility management to a second communication node, and / or receiving a first feedback message for mobility management from the second communication node. The first request message indicates at least one target communication object, which is at least one of a recommended target communication object and a non-recommended target communication object. The first feedback message indicates at least one target communication object, which is at least one of a configured target communication object and a rejected target communication object. Therefore, by sending a request message from the first communication node to the second communication node to indicate at least one recommended target communication object and / or at least one non-recommended target communication object, the first communication node can participate in the selection of target communication objects, ensuring that the selected target communication objects conform to the mobility management requirements initiated by the first communication node. Conversely, by sending a feedback message from the second communication node to the first communication node to indicate configured and / or rejected target communication objects, the first communication node can promptly learn about configured and / or rejected target communication objects, thus keeping mobility management within the control of the first communication node.

[0096] Please see Figure 6 , Figure 6 This is a flowchart illustrating another configuration information transmission method provided in this embodiment. This configuration information transmission method can be executed by a first communication node, which can be... Figure 4 The S-MN or S-SN on the network device side of the communication system shown is not limited in this disclosure. For an explanation of the S-MN or S-SN, please refer to the relevant description in any embodiment of this disclosure, which will not be repeated here.

[0097] The configuration information transmission method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in related technologies.

[0098] like Figure 6 As shown, the configuration information transmission method may include, but is not limited to, the following steps:

[0099] Step 601: Send a first request message for mobility management to the second communication node, and / or receive a first feedback message for mobility management from the second communication node, wherein the first feedback message includes a feedback message accepting mobility management and / or a feedback message rejecting mobility management.

[0100] Wherein, the first request message indicates at least one target communication object, which is at least one of a recommended configuration target communication object and a non-recommended configuration target communication object; the first feedback message indicates at least one target communication object, which is at least one of a configured target communication object and a rejected configuration target communication object.

[0101] The explanation of the second communication node and the target communication object can be found in the relevant description in any embodiment of this disclosure, and will not be repeated here.

[0102] It should be noted that step 601 can be found in the relevant description in any embodiment of this disclosure, and will not be repeated here.

[0103] In one possible implementation of this disclosure, if the first feedback message indicates that at least one configured target communication object is a target communication object recommended for configuration in the first request message, then the first feedback message is a feedback message for accepting mobility management.

[0104] For example, after receiving the first request message, if the second communication node selects at least one of the recommended target communication objects in the first request message, it indicates that the second communication node accepts the mobility management process, and the first communication node can continue the subsequent mobility management process. At this time, the second communication node can use the selected target communication object as the configured target communication object and send a feedback message of accepting mobility management to the first communication node.

[0105] For example, the second communication node and / or the corresponding configured target communication object that sends the feedback message accepting mobility management can reserve resources for this mobility management request.

[0106] In another possible implementation of this disclosure, if none of the configured target communication objects indicated by the first feedback message are the target communication objects recommended for configuration in the first request message, the first feedback message is a feedback message rejecting mobility management.

[0107] For example, after receiving the first request message, if the second communication node selects at least one target communication object in addition to all the recommended target communication objects in the first request message, it indicates that the second communication node has rejected all the recommended target communication objects in the first request message. At this time, the second communication node can send a feedback message of rejection of mobility management to the first communication node.

[0108] For example, the second communication node and / or the corresponding selected target communication object that sends a feedback message rejecting mobility management may not reserve resources for this mobility management request.

[0109] In another possible implementation of this disclosure, if the target communication objects for which the configuration is rejected, as indicated by the first feedback message, include all the target communication objects recommended for configuration in the first request message, then the first feedback message is a feedback message for rejecting mobility management.

[0110] For example, after receiving the first request message, if the second communication node rejects all the recommended target communication objects in the first request message or is unable to select a configurable target communication object from all the recommended target communication objects in the first request message, the second communication node may send a feedback message of rejection of mobility management to the first communication node.

[0111] For example, a second communication node that sends a feedback message rejecting mobility management may not reserve resources for this mobility management request.

[0112] In another possible implementation of this disclosure, if the first feedback message is a feedback message accepting mobility management when the first feedback message indicates that at least one configured target communication object is not a target communication object that is not recommended for configuration in the first request message.

[0113] For example, after receiving the first request message, if the second communication node selects at least one target communication object in addition to all the target communication objects that are not recommended for configuration in the first request message, it indicates that the second communication node has not rejected the mobility management process, and the first communication node can continue the subsequent mobility management process. At this time, the second communication node can use the selected target communication object as the configured target communication object and send a feedback message to the first communication node accepting mobility management.

[0114] For example, the second communication node and / or the corresponding configured target communication object that sends the feedback message accepting mobility management can reserve resources for this mobility management request.

[0115] In another possible implementation of this disclosure, if the target communication objects selected by the second communication node are all target communication objects that are not recommended for configuration in the first request message, the first feedback message is a feedback message that rejects mobility management.

[0116] For example, after receiving the first request message, if the second communication node cannot select at least one target communication object from among all the deprecated target communication objects in the first request message, then the second communication node can send a feedback message of denial of mobility management to the first communication node. Alternatively, if the second communication node selects at least one deprecated target communication object from the first request message after receiving it, then the second communication node can send a feedback message of denial of mobility management to the first communication node.

[0117] For example, a second communication node that sends a feedback message rejecting mobility management may not reserve resources for this mobility management request.

[0118] In another possible implementation of this disclosure, if the first feedback message is a feedback message accepting mobility management, where the target communication object rejected for configuration indicated by the first feedback message includes at least one target communication object that is not recommended for configuration in the first request message.

[0119] For example, after receiving the first request message, if the second communication node rejects the target communication object that is not recommended for configuration in the first request message, the second communication node can send a feedback message to the first communication node accepting mobility management.

[0120] For example, the second communication node and / or the corresponding configured target communication object that sends the feedback message accepting mobility management can reserve resources for this mobility management request.

[0121] In another possible implementation of this disclosure, at least one configured target communication object indicated by the first feedback message is a target communication object that is not recommended for configuration in the first request message, and the first feedback message is a feedback message accepting mobility management.

[0122] For example, after receiving the first request message, if the second communication node selects a target communication object that is not recommended for configuration in the first request message, the second communication node can also send a feedback message to the first communication node accepting mobility management.

[0123] For example, the second communication node and / or the corresponding configured target communication object that sends the feedback message accepting mobility management can reserve resources for this mobility management request.

[0124] In one possible implementation of this disclosure, regardless of whether the first request message received by the second communication node contains a recommended target communication object and / or a non-recommended target communication object, if the second communication node can configure at least one available target communication object, the first feedback message sent by the second communication node to the first communication node can be a feedback message accepting mobility management.

[0125] In one possible implementation of this disclosure, regardless of whether the first request message received by the second communication node contains a recommended target communication object and / or a non-recommended target communication object, if the second communication node cannot configure an available target communication object, the first feedback message sent by the second communication node to the first communication node can be a feedback message of rejection of mobility management.

[0126] As an example of an application scenario, taking the first communication node as S-MN and the second communication node as T-MN, S-MN initiates the MCG mobility management process. S-MN can send a first request message to T-MN. The first request message may include one or more MCGs recommended by S-MN for initiating the MCG mobility management process.

[0127] After receiving the first request message from the S-MN, the T-MN can determine a set of MCG configurations from the MCGs recommended by the S-MN and send a feedback message to the S-MN accepting mobility management. If the T-MN cannot determine a set of MCG configurations from the MCGs recommended by the S-MN, the T-MN can send a feedback message to the S-MN rejecting mobility management, and the process ends.

[0128] It should be noted that the various possible implementation methods mentioned above can be executed individually or in combination, and this disclosure does not impose any restrictions on this.

[0129] The configuration information transmission method of this disclosure embodiment, by sending a first request message from a first communication node to a second communication node, instructs the first communication node to recommend configuring at least one target communication object and / or to indicate that the first communication node does not recommend configuring at least one target communication object. This enables the first communication node to participate in the selection of target communication objects, ensuring that the selected target communication objects conform to the mobility management requirements initiated by the first communication node. And / or, by sending a first feedback message from the second communication node to the first communication node, instructing the second communication node to configure target communication objects and / or reject configure target communication objects, the first communication node can promptly learn about the configured target communication objects and / or rejected configure target communication objects, thereby keeping mobility management within the control of the first communication node.

[0130] It should be noted that the above-mentioned possible implementations can be executed individually or in combination, and this disclosure does not limit them.

[0131] Please see Figure 7 , Figure 7 This is a flowchart illustrating another configuration information transmission method provided in this embodiment. This configuration information transmission method can be executed by a first communication node, which can be... Figure 4 The S-MN on the network device side of the communication system shown.

[0132] The configuration information transmission method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in related technologies.

[0133] like Figure 7 As shown, the configuration information transmission method may include, but is not limited to, the following steps:

[0134] Step 701: Receive a second request message for mobility management from the source secondary node associated with the source primary node.

[0135] The second request message is used to indicate at least one target communication object that the source and auxiliary nodes recommend configuring, and / or at least one target communication object that the source and auxiliary nodes do not recommend configuring.

[0136] In this embodiment of the disclosure, the S-MN can receive a second mobility management request message sent by the S-SN associated with the S-MN, wherein the second request message is used to indicate at least one target communication object that the S-SN recommends to configure, and / or the second request message is used to indicate at least one target communication object that the S-SN does not recommend to configure.

[0137] Step 702: Send a first request message for mobility management to the second communication node, and / or receive a first feedback message for mobility management from the second communication node.

[0138] The first request message indicates at least one target communication object, which is at least one of a recommended target communication object (e.g., at least one target communication object recommended by the S-SN) and a non-recommended target communication object (e.g., at least one target communication object not recommended by the S-SN); the first feedback message indicates at least one target communication object, which is at least one of a configured target communication object and a rejected target communication object.

[0139] In this embodiment of the disclosure, after receiving a second mobility management request message sent by the S-SN associated with the S-MN, the S-MN can generate a first request message based on the second request message. That is, the S-MN can generate a first request message based on at least one target communication object recommended by the S-SN and / or at least one target communication object not recommended by the S-SN, and send the first request message to the second communication node.

[0140] It should be noted that step 702 can be implemented in any of the embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0141] The configuration information transmission method of this disclosure embodiment, by sending a first request message from the S-MN to the second communication node, indicates at least one target communication object recommended for configuration and / or at least one target communication object not recommended for configuration by the S-SN associated with the S-MN. This enables the S-SN or S-MN to participate in the selection of target communication objects, ensuring that the selected target communication objects conform to the mobility management requirements initiated by the S-MN. And / or, by sending a first feedback message from the second communication node to the S-MN, it indicates the target communication objects configured and / or the target communication objects rejected for configuration by the second communication node. This allows the S-MN to promptly know the configured target communication objects and / or the rejected target communication objects, thereby keeping mobility management within the control of the S-MN.

[0142] It should be noted that the above-mentioned possible implementations can be executed individually or in combination, and this disclosure does not limit them.

[0143] Please see Figure 8 , Figure 8 This is a flowchart illustrating another configuration information transmission method provided in this embodiment. This configuration information transmission method can be executed by a first communication node, which can be... Figure 4 The S-MN on the network device side of the communication system shown.

[0144] The configuration information transmission method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in related technologies.

[0145] like Figure 8 As shown, the configuration information transmission method may include, but is not limited to, the following steps:

[0146] Step 801: Receive a second request message for mobility management from the source secondary node associated with the source primary node.

[0147] The second request message is used to indicate at least one target communication object that the source and auxiliary nodes recommend configuring, and / or at least one target communication object that the source and auxiliary nodes do not recommend configuring.

[0148] Step 802: Send a first request message for mobility management to the second communication node, and / or receive a first feedback message for mobility management from the second communication node.

[0149] Wherein, the first request message indicates at least one target communication object, which is at least one of a recommended configuration target communication object and a non-recommended configuration target communication object; the first feedback message indicates at least one target communication object, which is at least one of a configured target communication object and a rejected configuration target communication object.

[0150] Steps 801 to 802 can be implemented in any of the embodiments of this disclosure. This disclosure does not limit the implementation of these steps and will not elaborate further.

[0151] Step 803: Based on the first feedback message for mobility management received from the second communication node, send a second feedback message to the source auxiliary node associated with the source primary node; and / or, if at least one first feedback message is not received from the second communication node within a set time period, send a feedback message of rejection of mobility management to the source auxiliary node associated with the source node.

[0152] The set duration is a pre-set duration threshold.

[0153] In this embodiment of the disclosure, when the S-MN receives a first feedback message from the second communication node within a set time period, the S-MN can send a second feedback message to the source auxiliary node associated with the source primary node based on the first feedback message of mobility management received from the second communication node.

[0154] As an example, when the first feedback message received by the S-MN is a feedback message accepting mobility management, the second feedback message sent by the S-MN to the S-SN is a feedback message accepting mobility management; and / or, when the first feedback message received by the S-MN is a feedback message rejecting mobility management, the second feedback message sent by the S-MN to the S-SN is a feedback message rejecting mobility management.

[0155] In this embodiment of the disclosure, if the S-MN does not receive at least one first feedback message from the second communication node within a set time period, the S-MN may send a feedback message of rejection of mobility management to the S-SN.

[0156] In any embodiment of this disclosure, the first request message may also be used to indicate recommended configuration information for the target communication object.

[0157] In any embodiment of this disclosure, the first feedback message may also be used to indicate the configuration information of the configured target communication object.

[0158] The configuration information transmission method of this disclosure embodiment, by having the S-MN receive a second mobility management request message sent by the S-SN associated with the S-MN and send a first request message to the second communication node, indicates at least one target communication object recommended for configuration and / or at least one target communication object not recommended for configuration by the S-SN associated with the S-MN. This enables the S-SN or S-MN to participate in the selection of target communication objects, ensuring that the selected target communication objects conform to the mobility management requirements initiated by the S-MN or S-SN. And / or, by having the second communication node send a first feedback message to the S-MN, it indicates the target communication objects configured and / or the target communication objects rejected for configuration by the second communication node. This allows the S-MN to promptly know the configured target communication objects and / or the rejected target communication objects, thereby keeping mobility management within the control of the S-MN. By sending a second feedback message from the S-MN to the S-SN, the second communication node can indicate the configured target communication object and / or the rejected target communication object. This allows the S-SN to know the configured target communication object and / or the rejected target communication object in a timely manner, thus keeping mobility management within the control of the S-SN.

[0159] It should be noted that the above-mentioned possible implementations can be executed individually or in combination, and this disclosure does not limit them.

[0160] Please see Figure 9 , Figure 9 This is a flowchart illustrating another configuration information transmission method provided in this embodiment. This configuration information transmission method can be executed by a first communication node, which can be... Figure 4 The S-MN or S-SN on the network device side of the communication system shown. For an explanation of the S-MN or S-SN, please refer to the relevant description in any embodiment of this disclosure, which will not be repeated here.

[0161] The configuration information transmission method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in related technologies.

[0162] like Figure 9 As shown, the configuration information transmission method may include, but is not limited to, the following steps:

[0163] Step 901: Send a first request message for mobility management to the second communication node, and / or receive a first feedback message for mobility management from the second communication node; wherein the first request message indicates at least one target communication object, which is at least one of a recommended target communication object and a non-recommended target communication object, and the first request message may also be used to explicitly or implicitly indicate a third communication node.

[0164] The first feedback message indicates at least one target communication object, which is at least one of a configured target communication object and a target communication object that refuses to be configured.

[0165] It should be noted that step 901 can be implemented in any of the embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0166] In one possible implementation of this disclosure, when the target communication object includes a target node, the third communication node may be a node used for communication between the second communication node and the target communication object in the first request message, and / or, when the target communication object includes a target cell and / or a target cell group, the third communication node may be a node used for communication between the second communication node and the target node corresponding to the target communication object in the first request message.

[0167] In another possible implementation of the embodiments of this disclosure, when the target communication object includes a target node, the third communication node may be at least one target communication object recommended for configuration in the first request message; or, when the target communication object includes a target cell and / or a target cell group, the third communication node may be at least one target node corresponding to the target communication object recommended for configuration in the first request message.

[0168] The number of third communication nodes is at least one. For example, when there is one target communication object or a target node corresponding to the target communication object, there can be one third communication node. When there are multiple target communication objects or target nodes corresponding to the target communication object, there can be multiple third communication nodes.

[0169] In this embodiment of the disclosure, the first request message sent by the first communication node to the second communication node can be used not only to indicate at least one target communication object, but also to explicitly or implicitly indicate a third communication node. Accordingly, after receiving the first request message, the second communication node can send a third request message for mobility management to at least one third communication node based on the first request message.

[0170] In one implementation, the third request message may be used to indicate at least one target communication object that the second communication node recommends to configure, and / or the third request message may be used to indicate at least one target communication object that the second communication node does not recommend to configure.

[0171] As an example, a second communication node may determine at least one target communication object that it recommends to configure, and / or determine at least one target communication object that it does not recommend to configure, based on at least one target communication object indicated by the first request message, and generate a third request message based on the at least one target communication object that it recommends to configure and / or the at least one target communication object that it does not recommend to configure, and send the third request message to at least one third communication node.

[0172] In this embodiment of the disclosure, after receiving the third request message, the third communication node can send a third feedback message to the second communication node according to the third request message. Correspondingly, after receiving the third feedback message sent by at least one third communication node, the second communication node can generate a first feedback message according to the third feedback message sent by at least one third communication node and send the first feedback message to the first communication node.

[0173] As an example, when the second communication node receives at least one third feedback message that is a feedback message accepting mobility management, the first feedback message generated by the second communication node can be a feedback message accepting mobility management.

[0174] As another example, when all the third feedback messages received by the second communication node are feedback messages that reject mobility management, the first feedback message generated by the second communication node is a feedback message that rejects mobility management.

[0175] It should be noted that when the second communication node does not receive a third feedback message from any third communication node within a set time period, the first feedback message generated by the second communication node can be a feedback message of rejection of mobility management.

[0176] As an example of an application scenario, taking the first communication node as S-MN, the second communication node as T-MN, and the third communication object and the target communication object as T-SN, S-MN can initiate the MCG and SCG mobility management process. The first request message sent by S-MN to T-MN can carry one or more T-SNs recommended by T-MN.

[0177] After receiving the first request message from the S-MN, if the T-MN cannot determine a set of MCG configurations, it can send a feedback message of denial of mobility management to the S-MN, and the process ends. If the T-MN can determine a set of MCG configurations, it can send a third request message to one or more T-SNs with the above-recommended configuration.

[0178] After receiving the third request message from the T-MN, if the T-SN can determine a set of SCG configurations based on the third request message, the T-SN can send a feedback message accepting mobility management to the T-MN. If the T-SN cannot determine a set of SCG configurations based on the third request message, the T-SN can send a feedback message rejecting mobility management to the T-MN.

[0179] When the T-MN receives a feedback message accepting mobility management from at least one recommended configured T-SN, the T-MN can send a feedback message accepting mobility management to the S-MN, confirming acceptance of the mobility management process initiated by the S-MN. This feedback message may carry the configuration of one or more configured T-SNs and / or SCGs (referred to in this disclosure as the configuration information of the configured target communication object). When the T-MN receives only feedback messages rejecting mobility management, the T-MN can send a feedback message rejecting mobility management to the S-MN, and the process ends.

[0180] As another application scenario, taking the first communication node as S-MN, the second communication node as T-MN, and the third communication object and the target communication object as T-SN as an example, S-MN initiates the MCG mobility management process. At the same time or before this, the S-SN associated with S-MN initiates the SCG mobility management process. The S-SN can send a second request message to S-MN. The second request message can carry one or more T-SNs or SCGs recommended by S-SN and / or MCGs recommended by S-MN, for initiating the SCG mobility management process.

[0181] Upon receiving the second request message, if the S-MN determines that it cannot perform mobility management for the SCG, it can send a feedback message rejecting mobility management to the S-SN, and the process ends. If the S-MN determines that it can perform mobility management for the SCG, it can initiate the mobility management process for the MCG and simultaneously perform the mobility management process for the SCG initiated by the S-SN. The S-MN can send a first request message to the T-MN, which carries one or more T-SNs or SCGs recommended for configuration in the second request message.

[0182] After receiving the first request message from the S-MN, if the T-MN cannot determine a set of MCG configurations from the MCGs recommended by the S-MN, the T-MN can send a feedback message of denial of mobility management to the S-MN, and the process ends. If the T-MN can determine a set of MCG configurations from the MCGs recommended by the S-MN, the T-MN can send a third request message to one or more T-SNs with the recommended configuration.

[0183] After receiving the third request message from the T-MN, if the T-SN can determine a set of SCG configurations based on the third request message, the T-SN can send a feedback message accepting mobility management to the T-MN. If the T-SN cannot determine a set of SCG configurations based on the third request message, the T-SN can send a feedback message rejecting mobility management to the T-MN.

[0184] When the T-MN receives a feedback message accepting mobility management from at least one recommended configured T-SN, the T-MN can send a feedback message accepting mobility management to the S-MN, confirming acceptance of the mobility management process initiated by the S-MN. This feedback message may carry the configuration of one or more configured T-SNs and / or SCGs (referred to in this disclosure as the configuration information of the configured target communication object). When the T-MN receives only feedback messages rejecting mobility management, the T-MN can send a feedback message rejecting mobility management to the S-MN, and the process ends.

[0185] If the S-MN receives at least one feedback message from the T-MN accepting mobility management, the S-MN can send a feedback message to the S-SN accepting mobility management, confirming acceptance of the mobility management process initiated by the S-SN. Furthermore, the feedback message sent by the S-MN to the S-SN accepting mobility management may also carry one or more of the following: the configured T-MN, the configured T-SN, the configuration of the MCG, and the configuration of the SCG. Conversely, if the S-MN receives only feedback messages rejecting mobility management, the S-MN can send a feedback message rejecting mobility management to the S-SN, and the process ends.

[0186] The configuration information transmission method of this disclosure embodiment, by sending a first request message from a first communication node to a second communication node, instructs the first communication node to recommend configuring at least one target communication object and / or instructs the first communication node not to recommend configuring at least one target communication object. This enables the first communication node to participate in the selection of target communication objects, ensuring that the selected target communication objects conform to the mobility management requirements initiated by the first communication node. And / or, by sending a first feedback message from the second communication node to the first communication node, instructing the first communication node to indicate the configured target communication objects and / or the rejected target communication objects, the first communication node can promptly learn about the configured target communication objects and / or the rejected target communication objects, thereby keeping mobility management within the control of the first communication node.

[0187] It should be noted that the above-mentioned possible implementations can be executed individually or in combination, and this disclosure does not limit them.

[0188] Please see Figure 10 , Figure 10 This is a flowchart illustrating another configuration information transmission method provided in this embodiment. This configuration information transmission method can be executed by a first communication node, which can be... Figure 4 The S-MN, S-SN, or T-MN on the network device side of the communication system shown. For an explanation of S-MN or S-SN, please refer to the relevant description in any embodiment of this disclosure, and it will not be repeated here.

[0189] The configuration information transmission method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in related technologies.

[0190] like Figure 10 As shown, the configuration information transmission method may include, but is not limited to, the following steps:

[0191] Step 1001: Send a first request message for mobility management to the second communication node, and / or receive a first feedback message for mobility management from the second communication node, wherein mobility management includes, but is not limited to, at least one of the following: selective activation of cell groups; condition-triggered mobility management.

[0192] Wherein, the first request message indicates at least one target communication object, which is at least one of a recommended configuration target communication object and a non-recommended configuration target communication object; the first feedback message indicates at least one target communication object, which is at least one of a configured target communication object and a rejected configuration target communication object.

[0193] It should be noted that step 1001 can be implemented in any of the embodiments of this disclosure. This disclosure does not limit this and will not elaborate further.

[0194] In embodiments of this disclosure, mobility management includes, but is not limited to, at least one of the following: selective activation of cell groups; and condition-triggered mobility management.

[0195] In any embodiment of this disclosure, when the target communication object includes a target node and a target cell, the first request message can also be used to indicate the correspondence between the target node and the target cell; when the target communication object includes a target node and a target cell group, the first request message can also be used to indicate the correspondence between the target node and the target cell group.

[0196] It should be noted that a node can provide one cell or multiple cells. For example, the same target node can correspond to at least one target cell. In this disclosure, in order to facilitate the determination of the target communication object, the correspondence between the target node and the target cell can be indicated in the first request message. Thus, in this disclosure, the target cell corresponding to the target node can be queried according to the above correspondence, and the target node and the target cell corresponding to the target node can be regarded as the target communication object.

[0197] Similarly, a node can provide one cell group or multiple cell groups. For example, the same target node can correspond to at least one target cell group. In this disclosure, in order to facilitate the determination of the target communication object, the correspondence between the target node and the target cell group can be indicated in the first request message. Thus, in this disclosure, the target cell group corresponding to the target node can be queried according to the above correspondence, and the target node and the target cell group corresponding to the target node can be taken as the target communication object.

[0198] For example, the first request message may indicate at least one of the following: target MN and its associated MCG, target SN and its associated SCG, target MN and its associated PCell, and target SN and its associated PSCell.

[0199] In any embodiment of this disclosure, the first request message may include, but is not limited to, at least one of the following: a handover request message (for example, a handover request message may be used to request a handover of the primary cell or primary cell group); a secondary node add request message; a secondary node modify request message; and a secondary node change request message.

[0200] As an example, a handover request message can be sent from the source NG-RAN node to the target NG-RAN node. This message requests the preparation of resources for a handover. The transmission direction is from the source NG-RAN node to the target NG-RAN node.

[0201] As an example, a secondary node addition request message (S-NODE ADDITION REQUEST) can be sent from the primary NG-RAN (M-NG-RAN) node to the secondary NG-RAN (S-NG-RAN) node. This message requests the preparation of resources for dual connectivity operation for a specific UE. The transmission direction is from the M-NG-RAN node to the S-NG-RAN node.

[0202] As an example, a secondary node modification request message (S-NODE MODIFICATION REQUEST) can be sent from the M-NG-RAN node to the S-NG-RAN node. This message is used to request the preparation to modify S-NG-RAN node resources for a specific UE, query the current SCG configuration, or provide S-RLF (secondary-Radio Link Failure) related information to the S-NG-RAN node. The transmission direction is from the M-NG-RAN node to the S-NG-RAN node.

[0203] As an example, an S-NODE CHANGE REQUIRED message can be sent from an S-NG-RAN node to an M-NG-RAN node. This message triggers a change in the S-NG-RAN node. The transmission direction is from the S-NG-RAN node to the M-NG-RAN node.

[0204] In any embodiment of this disclosure, the feedback messages for accepting mobility management include, but are not limited to, at least one of the following: a handover request confirmation message; a secondary node addition request confirmation message; a secondary node modification request confirmation message; and a secondary node change confirmation message.

[0205] As an example, a handover request acknowledgment message can be sent from the target NG-RAN node to the source NG-RAN node. The message informs the source NG-RAN node about the prepared resources at the target. The transmission direction is from the target NG-RAN node to the source NG-RAN node.

[0206] As an example, the S-NODE ADDITION REQUESTACKNOWLEDGE message is sent from the S-NG-RAN node to the M-NG-RAN node. This message confirms that the S-NG-RAN node addition is ready. The transmission direction is from the S-NG-RAN node to the M-NG-RAN node.

[0207] As an example, the S-NODE MODIFICATION REQUESTACKNOWLEDGE message is transmitted from the S-NG-RAN to the M-NG-RAN node. This message confirms the M-NG-RAN node's request to modify the S-NG-RAN node resources for a specific UE. The transmission direction is from the S-NG-RAN node to the M-NG-RAN node.

[0208] As an example, a secondary node change confirmation message (S-NODE CHANGE CONFIRM) can be sent from the M-NG-RAN node to the S-NG-RAN node. This message indicates to the S-NG-RAN node that the preparation of the S-NG-RAN node initiated the S-NG-RAN node change was successful. The transmission direction is from the M-NG-RAN node to the S-NG-RAN node.

[0209] In any embodiment of this disclosure, the feedback messages for rejection of mobility management include, but are not limited to, at least one of the following: a handover preparation failure message; a secondary node add request rejection message; a secondary node modify request rejection message; and a secondary node change rejection message.

[0210] As an example, a HANDOVER PREPARATION FAILURE message can be sent from the target NG-RAN node to the source NG-RAN node. This message indicates that the handover preparation has failed. The transmission direction is from the target NG-RAN node to the source NG-RAN node.

[0211] As an example, an S-NODE ADDITION REQUEST REJECT message can be sent from the S-NG-RAN to the M-NG-RAN node. This message indicates to the M-NG-RAN node that the S-NG-RAN node AdditionPreparation has failed. The transmission direction is from the S-NG-RAN node to the M-NG-RAN node.

[0212] As an example, an S-NODE MODIFICATION REQUESTREJECT message can be sent from the S-NG-RAN to the M-NG-RAN node. This message indicates to the M-NG-RAN node that the M-NG-RAN node initiated S-NG-RAN node Modification Preparation has failed. The transmission direction is from the S-NG-RAN node to the M-NG-RAN node.

[0213] As an example, an S-NODE CHANGE REFUSE message can be sent from an M-NG-RAN node to an S-NG-RAN node. This message indicates to the S-NG-RAN node that the preparation of the S-NG-RAN node initiated S-NG-RAN node change has failed. The transmission direction is from the M-NG-RAN node to the S-NG-RAN node.

[0214] The configuration information transmission method of this disclosure embodiment, by sending a first request message from a first communication node to a second communication node, instructs the first communication node to recommend configuring at least one target communication object and / or instructs the first communication node not to recommend configuring at least one target communication object. This enables the first communication node to participate in the selection of target communication objects, ensuring that the selected target communication objects conform to the mobility management requirements initiated by the first communication node. And / or, by sending a first feedback message from the second communication node to the first communication node, instructing the first communication node to indicate the configured target communication objects and / or the rejected target communication objects, the first communication node can promptly learn about the configured target communication objects and / or the rejected target communication objects, thereby keeping mobility management within the control of the first communication node.

[0215] It should be noted that the above-mentioned possible implementations can be executed individually or in combination, and this disclosure does not limit them.

[0216] In any embodiment of this disclosure, a first communication node (or originating node) may initiate a mobility management process through a first request message for mobility management, wherein the first request message carries one or more target communication objects for recommended configuration, and / or the first request message carries one or more target communication objects for which configuration is not recommended.

[0217] In any embodiment of this disclosure, after receiving the first mobility management request message sent by the first communication node, the second communication node (or receiving node) can confirm acceptance or rejection of the mobility management process by sending a corresponding first feedback message. Furthermore, the first feedback message can carry one or more configured target communication objects, and / or carry rejected target communication objects in the first feedback message.

[0218] If the first request message for mobility management does not carry one or more target communication objects that are recommended for configuration, and / or does not carry one or more target communication objects that are not recommended for configuration, then the second communication node may also carry one or more configured target communication objects in the first feedback message, wherein the one or more configured target communication objects are determined by the second communication node.

[0219] For example: If the second communication node receives the first request message, the second communication node may also carry one or more configured target communication objects in the first feedback message, wherein the one or more configured target communication objects are determined by the second communication node.

[0220] In any embodiment of this disclosure, the first communication node may include S-MN and S-SN, and the second communication node may include T-MN and T-SN.

[0221] In any embodiment of this disclosure, the second communication node may select all or part of the target communication objects recommended in the first request message, or the second communication node may reject all or part of the target communication objects recommended in the first request message.

[0222] As an example, if the second communication node selects at least one recommended target communication object, it sends a feedback message to the first communication node to accept the mobility management process, and carries the configured target communication object and / or rejected target communication object in the feedback message.

[0223] As an example, if the second communication node rejects all the target communication objects of the recommended configuration, it can send a feedback message of rejection of mobility management to the first communication node, thus rejecting the mobility management process.

[0224] As an example, if the second communication node selects at least one target communication object other than the target communication object that is not recommended for configuration, it can send a feedback message to the first communication node to accept the mobility management process, and carry the configured target communication object and / or the rejected target communication object in the feedback message.

[0225] As an example, if the second communication object cannot select at least one target communication object other than the target communication object that is not recommended for configuration, it can send a feedback message of rejection of mobility management to the first communication object to reject the mobility management process.

[0226] As an example, if the second communication node selects a target communication object that is not recommended for configuration, it can also send a feedback message to the first communication node accepting mobility management, and carry the configured target communication object and / or the rejected target communication object in the feedback message.

[0227] For example, a second communication node and / or a corresponding configured target communication object that sends a feedback message accepting mobility management can reserve resources for this mobility management request.

[0228] For example, a second communication node that sends a feedback message rejecting mobility management may not reserve resources for this mobility management request.

[0229] In any embodiment of this disclosure, after receiving the first request message, the second communication node may also send a third request message to the target communication object (or the target node corresponding to the target communication object), and after receiving the third feedback message sent by the target communication object (or the target node corresponding to the target communication object), generate a first feedback message based on the third feedback message and send the first feedback message to the first communication node.

[0230] As an example, if the second communication node receives a third feedback message from at least one recommended configuration target communication object (or the target node corresponding to the target communication object) that is a feedback message accepting mobility management, then the first feedback message generated by the second communication node can be a feedback message accepting mobility management, and can carry the configured target communication object and / or the rejected target communication object in the first feedback message.

[0231] As an example, if the second communication node receives third feedback messages from all recommended target communication objects (or the target nodes corresponding to the target communication objects) that are all rejections of mobility management, then the first feedback message generated by the second communication node can be a rejection of mobility management. Alternatively, if the second communication node does not receive any third feedback messages, then the first feedback message generated by the second communication node can be a rejection of mobility management.

[0232] The process of including at least one deprecated target communication object in the first request message for mobility management is similar to the process of including a recommended target communication object, and will not be described in detail here.

[0233] If the second communication node sends a third request message to the target communication object (or the target node corresponding to the target communication object), the target communication object needs to be indicated in the third request message.

[0234] In any embodiment of this disclosure, if the second communication node, after receiving the first request message, is unable or unwilling to directly send a third request message to the target communication object (or the target node corresponding to the target communication object), the second communication node may send a third request message for mobility management to an associated node (i.e., the third communication node in this disclosure, which may be a node used for communication between the second communication node and the target communication object in the first request message; and / or, the third communication node may be a node used for communication between the second communication node and the target node corresponding to the target communication object in the first request message), and the associated node sends a third feedback message to the second communication node. The associated node is a node that needs to be associated with the target communication object (or the target node corresponding to the target communication object) included in the first request message during the mobility management process.

[0235] As an example, if the second communication node receives a third feedback message from at least one associated node that is a feedback message accepting mobility management, then the first feedback message sent by the second communication node to the first communication node is also a feedback message accepting mobility management.

[0236] As an example, if the second communication node receives third feedback messages from all associated nodes that are rejections of mobility management, then the first feedback message sent by the second communication node to the first communication node is also a rejection of mobility management. Alternatively, if the second communication node does not receive any feedback messages, then the first feedback message sent by the second communication node to the first communication node is a rejection of mobility management.

[0237] As an example, the associated node can be included in the first request message for mobility management. Optionally, the first request message can include the target node corresponding to the associated node.

[0238] In any embodiment of this disclosure, when the target communication object includes both a target node and a target cell, the first request message may also carry the correspondence between the target node and the target cell. For example, the recommended configuration of the target communication object may include the correspondence between the target node and the target cell. When the target communication object includes both a target node and a target cell group, the first request message may also carry the correspondence between the target node and the target cell group. For example, the recommended configuration of the target communication object may include the correspondence between the target node and the target cell group.

[0239] For example, the first request message may indicate at least one of the following: target MN and its associated MCG, target SN and its associated SCG, target MN and its associated PCell, and target SN and its associated PSCell.

[0240] In any embodiment of this disclosure, the first request message for mobility management includes, but is not limited to, one or more of the following messages: handover request message; SN add request message; SN modify request message; SN change request message.

[0241] In any embodiment of this disclosure, the first feedback message for mobility management includes, but is not limited to, one or more of the following messages:

[0242] Receive feedback messages from mobility management: handover request confirmation message; SN add request confirmation message; SN modify request confirmation message; SN change confirmation message;

[0243] Rejection of mobility management feedback messages: handover preparation failure message; SN adds request rejection message; SN modifies request rejection message; SN changes rejection message.

[0244] In any embodiment of this disclosure, when the first request message carries one or more target communication objects that are recommended (or not recommended) for configuration, it can be represented by including the identifier of the target communication object; when the first feedback message carries one or more target communication objects that are configured (or rejected for configuration), it can be represented by including the identifier of the target communication object.

[0245] In any embodiment of this disclosure, the first request message may also carry recommended configuration information of the target communication object; the first feedback message may also carry configuration information of the configured target communication object.

[0246] Please see Figure 11 , Figure 11 This is a flowchart illustrating another configuration information transmission method provided in this embodiment. This configuration information transmission method can be executed by a second communication node, which can be... Figure 4 The T-MN, T-SN, or S-MN on the network device side of the communication system shown. For an explanation of T-MN, T-SN, or S-MN, please refer to the relevant description in any embodiment of this disclosure, and it will not be repeated here.

[0247] The configuration information transmission method can be executed alone, or it can be executed together with any embodiment of this disclosure or any possible implementation in the embodiment, or it can be executed together with any technical solution in related technologies.

[0255] In one possible implementation of this disclosure, the second communication node may further send a third request message for mobility management to at least one third communication node based on the first request message; wherein the third request message is used to indicate at least one target communication object recommended for configuration by the second communication node, and / or at least one target communication object not recommended for configuration by the second communication node.

[0256] In one possible implementation of this disclosure, the second communication node, in response to receiving a third feedback message sent by at least one third communication node, determines a first feedback message based on the third feedback message sent by at least one third communication node; and / or, if no third feedback message is received from any third communication node within a set time period, determines that the first feedback message is a feedback message of rejection of mobility management.

[0261] In one possible implementation of this disclosure, the target communication object includes at least one of the following: a target node; a target cell; a target cell group.

[0265] It should be noted that the explanation of the configuration information transmission method executed by the first communication node in any of the foregoing embodiments also applies to the configuration information transmission method executed by the second communication node, and the implementation principle is similar, so it will not be repeated here.

[0266] The configuration information transmission method of this disclosure embodiment, by sending a first request message from a first communication node to a second communication node, instructs the first communication node to recommend configuring at least one target communication object and / or instructs the first communication node not to recommend configuring at least one target communication object. This enables the first communication node to participate in the selection of target communication objects, ensuring that the selected target communication objects conform to the mobility management requirements initiated by the first communication node. And / or, by sending a first feedback message from the second communication node to the first communication node, instructing the first communication node to indicate the configured target communication objects and / or the rejected target communication objects, the first communication node can promptly learn about the configured target communication objects and / or the rejected target communication objects, thereby keeping mobility management within the control of the first communication node.

[0267] It should be noted that the above-mentioned possible implementations can be executed individually or in combination, and this disclosure does not limit them.
