Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and particularly to a node control method, apparatus, and storage medium in a non-standalone networking structure. Background Art

[0002] With the rapid development of communication technologies, 4G networks have been seamlessly covered. The 5G non-standalone (NSA) architecture is the networking method for mobile network operators, that is, without building a new 5G core network, but deploying the 5G network by leveraging the 4G radio air interface (the NSA radio anchor is in 4G). The 5G carrier only carries user data, and its control signaling is still transmitted through the 4G network.

[0003] From current tests, when the NSA network conducts high-speed services after a user randomly accesses, resetting or upgrading the base station on the 5G New Radio (NR) side may cause the disconnection of the Evolved NodeB Dual Connectivity (ENDC) link, resulting in the problem that the 5G users are lost in the NR side cell. At this time, the user may still be continuously attempting to access the NR side on the long term evolution (LTE) system side, and it takes a long time for the NR cell and the ENDC link to return to normal, which may cause resource waste and power consumption, etc. Summary of the Invention

[0070] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present disclosure belong to the scope of protection of the present disclosure.

[0071] In the embodiments of the present disclosure, the term "and / or" describes the association relationship of associated objects and indicates that three relationships may exist. For example, A and / or B may represent three cases: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0072] The following describes a node control method, apparatus, and storage medium in a non-standalone networking structure according to an embodiment of the present disclosure with reference to the accompanying drawings.

[0073] It should be noted that the technical solutions provided in the embodiments of the present disclosure can be applied to multiple systems, especially 5G systems. For example, the applicable systems may be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a long term evolution advanced (LTE-A) system, a universal mobile telecommunication system (UMTS), a worldwide interoperability for microwave access (WiMAX) system, a 5G New Radio (NR) system, etc. Both terminal devices and network-side devices are included in these multiple systems. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0074] Figure 1 is a schematic flowchart of a node control method in a non-standalone networking structure according to an embodiment of the present disclosure. The node control method in the non-standalone networking structure is applied to a master node.

[0075] As Figure 1 shown, the method includes:

[0076] Step 101: Control the available state of the user equipment (UE) survival detection function of the master node according to the establishment state of the ENDC link between the master node and the secondary node.

[0077] In a non-standalone networking structure, it may include a 4G LTE network, a 5G NR network, etc. Correspondingly, the master node may be a base station node on the 4G LTE network side in the NSA network, and the secondary node may be a base station node on the 5G NR network side.

[0078] It can be understood that in the NSA network, there is no signaling radio bearer (SRB) on the NR air interface, only data radio bearer (DRB). All radio resource control (RRC) signaling can only be transmitted through the LTE side. Therefore, when the UE accesses the 5G network, it needs to first send an access request to the 4G base station, and then the 4G base station sends the access request to the 5G base station. The 5G base station can return a response message, which may include whether to allow the establishment of the ENDC link between the master node and the secondary node. If the 5G base station is currently in an unavailable state, such as during upgrade, reset, or failure, the response message may indicate that the ENDC link establishment fails. If the 5G base station is working properly, the response message may allow the successful establishment of the ENDC link, and then the UE can access the available cell in the 5G network according to the access process in the related technology.

[0079] In the related technology, in the commercial network, the UE survival detection function of the LTE cell and the NSA cell has always been in an available state, and the survival detection period is short. The UE in the idle state will be automatically released. In the outdoor network, the 5G user uplink is set with a buffer occupancy (BO). Even if the UE does not perform a file transfer protocol (FTP) service after accessing the NR cell, it will not be released.

[0080] When the 5G base station is in an unavailable state, such as during upgrade or reset, the ENDC link is disconnected, and the UE leaves the NR cell and stays in the LTE cell. Since the UE survival detection function of the LTE cell is in an available state, the UE will be periodically released and automatically detect the NR cell signal to attempt access. This will repeatedly generate a large number of signaling for measurement, re-access, and release until the base station upgrade is successful and the ENDC link is restored to be established, and the UE successfully accesses the NR. During the process of the 5G base station upgrade and recovery, the UE and the network repeatedly interact, which may generate a large amount of information, thus possibly causing increased power consumption of the terminal and corresponding increase in power consumption of the base station, and occupying more space.

[0081] In the embodiments of the present disclosure, the available state of the user equipment (UE) survival detection function of the master node can be controlled according to the establishment status of the ENDC link between the master node and the secondary node.

[0082] For example, when the ENDC link between the master node and the secondary node is successfully established, the UE survival detection function can be controlled to be in an available state, so that the UE can successfully access the NR system. If the ENDC link between the master node and the secondary node is not successfully established, the UE survival detection function can be controlled to be in an unavailable state. This can avoid a large number of signaling for measurement re-access and release by the UE, reduce the power consumption of the terminal and the base station, and thus avoid resource waste.

[0083] In the embodiments of the present disclosure, the available state of the UE survival detection function of the master node can be controlled according to the establishment status of the ENDC link between the master node and the secondary node, thereby reducing power consumption, effectively avoiding resource waste, and improving utilization efficiency.

[0084] Figure 2 FIG. is a schematic flow chart of a node control method in a non-standalone networking structure provided by an embodiment of the present disclosure. The node control method in the non-standalone networking structure is applied to a master node.

[0085] As Figure 2 shown, the method includes:

[0086] Step 201, receiving a secondary station addition response message sent by the secondary node.

[0087] Among them, when the UE accesses the 5G network, it needs to first send an access request to the 4G base station, and then the 4G base station sends the access request to the 5G base station. The 5G base station can return a secondary station addition response message, and then the master node can receive the secondary station addition response message sent by the secondary node.

[0088] In addition, the secondary station addition response message may include information related to an evolved radio access bearer (E-RAB), or may also include interface establishment information, tunnel establishment information, relevant characters of the response message, etc. The present disclosure does not limit this.

[0089] Step 202, determining the establishment status of the ENDC link according to the value of a specified character in the secondary station addition response message.

[0090] Among them, the specified character can be one or multiple, so that it is possible to determine whether the ENDC link is successfully established according to different values of the specified character in the secondary station addition response message.

[0091] For example, when the specified character is included in the response message added by the secondary station, it can be determined that the ENDC link is successfully established.

[0092] Alternatively, in response to the value of the specified character being the first specified value, it is determined that the ENDC link is successfully established.

[0093] Alternatively, in response to the value of the specified character being the second specified value, it is determined that the ENDC link is not established.

[0094] For example, according to the network protocol or a prior agreement, a certain character in the response message added by the secondary station can be specified as the specified character.

[0095] For example, if the specified character is XXX and XXX is included in the response message added by the secondary station, it can be determined that the ENDC link is successfully established.

[0096] Alternatively, according to the agreement, the first character is the specified character, the first specified value can be A, and the second specified value can be B. If the value of the first character in the received response message added by the secondary station is A, it can be determined that the ENDC link is successfully established. Alternatively, if the value of the first character in the received response message added by the secondary station is B, it can be determined that the ENDC link is not established.

[0097] Alternatively, the specified character can be the last two characters in the response message added by the secondary station, the first specified value can be 11, and the second specified value can be 00. If the value of the last two characters in the received response message added by the secondary station is 11, it can be determined that the ENDC link is successfully established. Alternatively, when the value of the last two characters in the received response message added by the secondary station is 00, it can be determined that the ENDC link is not established.

[0098] It should be noted that the above examples are only for illustration and cannot be used to limit the specified character and its value, etc. in the response message added by the secondary station in the embodiments of the present disclosure.

[0099] Step 203: Control the available state of the scheduling algorithm associated with the UE survival detection function in the media access control (MAC) layer of the master node.

[0100] Among them, the scheduling algorithm associated with the UE survival detection function can be an algorithm agreed in advance according to the network protocol, and the present disclosure does not limit this.

[0101] In addition, when the ENDC link between the master node and the secondary node is not established, the scheduling algorithm associated with the UE alive detection function in the MAC layer of the master node can be set to the off and unavailable state, so that the UE will no longer be periodically released and automatically detect NR cell information for access attempts, avoiding a large amount of interaction information generated among various network elements. When the ENDC link between the master node and the secondary node is established, the scheduling algorithm associated with the UE alive detection function in the MAC layer of the master node can be set to the on and available state, and the UE can successfully access the NR network. Thus, the availability state of the scheduling algorithm associated with the UE alive detection function in the MAC layer of the master node can be controlled according to the establishment state of the ENDC link between the master node and the secondary node.

[0102] It can be understood that in the detection of the ENDC link on the 4G base station side of the NSA architecture, the detection result can trigger the RRC to use the scheduling algorithm associated with the UE alive detection function in the MAC layer of the master node, and the 4G base station can add a monitoring point for whether the ENDC X2 establishment between the 5G base stations fails.

[0103] For example, when the ENDC link between the master node and the secondary node is disconnected, the 4G base station can initiate an ENDC X2 establishment request. If the 5G base station replies to the 4G base station that the ENDC X2 establishment fails, the LTE cell RRC can trigger the scheduling algorithm associated with the UE alive detection function in the MAC layer of the master node to the off state, and the UE remains in the connected state in the LTE cell RRC, thus avoiding a large amount of interaction information generated due to RRC release.

[0104] Or, if the 5G base station replies to the 4G base station that the ENDC X2 establishment is successful, the LTE cell RRC can trigger the scheduling algorithm associated with the UE alive detection function in the MAC layer to the available state, and the UE can successfully access the NR.

[0105] Thus, during the upgrade and reset process of the 5G base station, the availability state of the scheduling algorithm associated with the UE alive detection function in the MAC layer of the master node can be controlled according to the establishment state of the ENDC link between the master node and the secondary node.

[0106] When the ENDC link between the master node and the secondary node is not successfully established, the scheduling algorithm associated with the UE alive detection function in the MAC layer of the master node can be controlled to be in the unavailable state, thereby reducing the information generated by the interaction between the UE and the network, avoiding a large amount of interaction information generated among various network elements, achieving energy saving for the terminal and the base station, and also avoiding a large amount of redundant information occupying the storage resources of the operator's FTP server, thus reducing resource waste and further improving the user perception.

[0107] In an embodiment of the present disclosure, a secondary station addition acknowledgment message sent by a secondary node may be received first, and then the establishment status of the ENDC link may be determined according to the value of a specified character in the secondary station addition acknowledgment message, so that the available status of a scheduling algorithm associated with the UE survival detection function in the media access control (MAC) layer of the master node can be controlled. Thus, according to the received secondary station addition acknowledgment message, the establishment status of the ENDC link can be determined, and then the control of the scheduling algorithm associated with the UE survival detection function in the MAC layer can be implemented, so that energy conservation of the terminal and the base station can be achieved, resource waste can be reduced, and utilization rate can be improved.

[0108] Figure 3 FIG. 4 is a schematic flowchart of a node control method in a non-standalone networking structure according to an embodiment of the present disclosure. The node control method in the non-standalone networking structure is applied to a master node.

[0109] As Figure 3 shown, the method includes:

[0110] Step 301, controlling the available status of the user equipment (UE) survival detection function of the master node according to the establishment status of the ENDC link between the master node and the secondary node.

[0111] Optionally, when the ENDC link between the master node and the secondary node is in a successfully established state, the UE survival detection function of the master node may be set to an available state.

[0112] Among them, the UE survival detection function of the master node may be made available by starting the UE survival detection algorithm of the master node.

[0113] It can be understood that after the UE survival detection algorithm of the master node is started, the UE survival detection function of the master node is in an available state, and UE survival detection can be performed.

[0114] Alternatively, the UE survival detection function of the master node may also be made available by setting the detection period of the UE survival detection algorithm of the master node to a first specified value.

[0115] Among them, the first specified value may be a pre-set value, such as 10 seconds, 12 seconds, etc. The present disclosure does not limit this.

[0116] For example, the detection period of the UE survival detection algorithm of the master node is set to 10 seconds. Thus, the master node can automatically perform UE survival detection every 10 seconds.

[0117] It should be noted that the above examples are only for illustration and cannot be used to limit the first specified value, the available status of the UE survival detection function, etc. in the embodiments of the present disclosure.

[0118] Optionally, when the ENDC link between the master node and the secondary node fails to be established, the UE alive detection function of the master node can be set to an unavailable state.

[0119] Among them, the UE alive detection function of the master node can be made unavailable by turning off the UE alive detection algorithm of the master node.

[0120] It can be understood that after the UE alive detection algorithm of the master node is turned off, the UE alive detection function of the master node will be in an unavailable state and will no longer perform UE alive detection.

[0121] Alternatively, when the UE alive detection algorithm of the master node is in an enabled state, the detection period of the UE alive detection algorithm can be adjusted from a first specified value to a second specified value, where the second specified value is greater than the first specified value.

[0122] For example, the first specified value is 10 seconds and the second specified value can be 10 minutes. Thus, after the master node finishes the current UE alive detection, it will perform UE alive detection again after 10 minutes.

[0123] It should be noted that the above examples are only for illustration and cannot be used to limit the first specified value, the second specified value, the available state of the UE alive detection function, etc. in the embodiments of the present disclosure.

[0124] Step 302, when the UE alive detection function is in an available state, send a secondary station addition request to the secondary node based on the specified UE alive detection period.

[0125] Among them, the specified UE alive detection period can be 10 seconds, 13 seconds, etc., and the present disclosure does not limit this.

[0126] For example, when the specified UE alive detection period is 10 seconds, after the ENDC link between the master node and the secondary node is successfully established, the UE alive detection function can be made available, and then a secondary station addition request can be sent to the secondary node every 10 seconds.

[0127] It should be noted that the above examples are only for illustration and cannot be used to limit the sending of the secondary station addition request to the secondary node, etc. in the embodiments of the present disclosure.

[0128] Optionally, there may be one cell or multiple cells in the secondary node, so an indication message can be sent to the UE to enable the UE to measure the cells in the secondary node first.

[0129] Specifically, in response to the UE alive detection function being in an available state, an indication message is sent to the UE, where the indication message is used to instruct the UE to measure the cells in the secondary node.

[0130] For example, when the UE alive detection function is in an available state, an indication message can be sent to the UE. The indication message can include: there are 3 cells in the secondary node, namely SN1, SN2, and SN3. The UE can then measure these three cells according to the indication message. If it is measured that the signal of SN2 is the strongest, it can be determined that the cell in the secondary node to be accessed is SN2, so that it is not necessary for the UE to access all three cells in the secondary node, improving the processing efficiency and resource utilization rate.

[0131] It should be noted that the above examples are only for illustration and cannot be used as a limitation on the cells in the secondary node and the measurement of cells in the embodiments of the present disclosure.

[0132] In the implementation of the present disclosure, according to the establishment state of the ENDC link between the master node and the secondary node, the available state of the UE alive detection function of the master node is controlled. Then, when the UE alive detection function is in an available state, a secondary station addition request can be sent to the secondary node based on a specified UE alive detection period. Thus, a secondary station addition request can be sent when the UE alive detection function is in an available state, reducing resource waste and improving utilization rate.
