Description

Technical Field

[0001] This application belongs to the field of wireless communication technology, and in particular relates to a method, apparatus and device for switching between multiple access points. Background Technology

[0002] In the 4G / 5G era, voice / video services for mobile users are provided by IMS (IP Multimedia Subsystem), which is built on EPC (Evolved Packet Core) / 5GC. The core feature of IMS is "access independence", that is, user terminals can support accessing IMS built on EPC / 5GC through various access methods, such as 5G NR, LTE, and WLAN.

[0003] Currently, the handover mechanisms defined in the 3GPP specifications are all between two access methods, and the handover between 5G NR and LTE is controlled by the network side, while the handover between 5G NR / LTE and WiFi is controlled by the terminal side.

[0004] When a user terminal simultaneously supports IMS services on these three access methods, that is, when the terminal simultaneously supports three voice services: VoNR / VoLTE / VoWiFi, problems may occur in the following handover scenarios: The terminal was originally camped on NR (or LTE). If the signal of the source network it is currently camped on becomes increasingly weak, the network side may initiate a handover process to the target network LTE (or NR). At the same time, the terminal side may also initiate a handover process to the target network WiFi. This will result in a waste of resource allocation for one side when switching to the target network and a decrease in the handover success rate. Summary of the Invention

[0005] The purpose of this application is to provide a method, apparatus, and device for switching between multiple access points, so as to avoid simultaneously initiating a handover to multiple target networks in scenarios that support multiple network types of access.

[0006] In a first aspect, this application provides a method for implementing handover between multiple access points, the method comprising:

[0007] When the access network handover conditions are met, measure the signal quality of the multiple networks to be accessed;

[0008] Based on the signal quality measurement results, perform a handover to a first target network that meets the handover requirements;

[0009] If, before successfully accessing the first target network, the second target network is found to meet the handover requirements, access to the second target network is prohibited, or access to the second target network is granted while access to the first target network is stopped.

[0010] In one possible implementation, when it is determined that the access network handover conditions are met, the signal quality of the multiple networks to be accessed is measured, including:

[0011] When the signal quality of the current access network is determined to be below the first threshold, a report is sent to the network side.

[0012] Receive the command from the network side to measure the signal quality of the first network, measure the signal quality of the first network to be accessed, and measure the signal quality of the second network to be accessed;

[0013] The first network is the network to be accessed that is triggered by the network side to perform the access handover, and the second network is the network to be accessed that is triggered by the terminal to perform the access handover.

[0014] In one possible implementation, based on signal quality measurement results, a handover to a first target network that meets the handover requirements is performed, including:

[0015] Based on the signal quality measurement results, the first target network whose signal quality meets the handover requirements is accessed earliest.

[0016] In one possible implementation, performing a handover to a first target network that meets the handover requirements includes:

[0017] When the first target network is determined to be the network to be accessed that triggers an access handover on the network side, the handover to the first target network is initiated by the network side; or

[0018] When the first target network is determined to be the network to be accessed by the terminal to trigger the access handover, the terminal initiates the handover to the first target network.

[0019] In one possible implementation, when the handover requirements of the second target network are measured to be met, access to the second target network and access to the first target network are stopped, including:

[0020] When a second target network whose signal quality meets the switching requirements is measured, and it is determined that the priority of the second target network is higher than that of the first target network, access to the second target network is granted and access to the first target network is stopped.

[0021] In one possible implementation, accessing the second target network and stopping access to the first target network includes:

[0022] When the second target network is determined to be the network to be accessed that the network side triggers to perform access handover, the signal quality of the second target network is reported to the network side to meet the handover requirements. The network side then initiates the handover to the second target network and stops the handover to the first target network.

[0023] When the second target network is determined to be the network to be accessed by the terminal to trigger the access handover, the terminal initiates the handover to the second target network and stops the handover to the first target network.

[0024] In one possible implementation, before successfully accessing the first target network, accessing the second target network and stopping access to the first target network includes:

[0025] If the signal quality of the currently accessed network is measured to be lower than the second threshold, and the handover to the first target network has not yet been successful, the system accesses the second target network and stops accessing the first target network. The second threshold is lower than the first threshold.

[0026] In one possible implementation, blocking access to the second target network includes:

[0027] If the priority of the second target network is determined to be lower than that of the first target network, and the signal quality of the currently accessed network has not fallen below the second threshold, access to the second target network is prohibited.

[0028] Secondly, this application provides an apparatus comprising:

[0029] The measurement module is used to measure the signal quality of multiple networks to be accessed when the access network handover conditions are met.

[0030] The first switching module is used to perform a switch to a first target network that meets the switching requirements based on the signal quality measurement results.

[0031] The second switching module is used to, before successfully accessing the first target network, if it is measured that the second target network meets the switching requirements, prohibit access to the second target network or access the second target network and stop accessing the first target network.

[0032] Thirdly, embodiments of this application provide an apparatus including at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform a method for implementing inter-access switching as described in any of the first aspects of this application.

[0033] Fourthly, embodiments of this application also provide a computer-readable storage medium, wherein when the instructions in the computer-readable storage medium are executed by the processor of a terminal device, the terminal device is able to perform a method for switching between multiple access points as described in any of the first aspects of this application.

[0034] The technical solutions provided by the embodiments of this application bring at least the following beneficial effects:

[0035] This application provides a method, apparatus, and device for implementing handover between multiple access networks. In scenarios that support multiple network types for access, when the source network does not meet the requirements and handover to multiple target networks is supported simultaneously, a preset handover rule is used to ensure that only one handover from the source network to a target network is initiated at the same time, avoiding simultaneous handover to multiple target networks. This can improve the handover success rate and reduce resource allocation waste. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0045] In the 4G / 5G era, voice / video services for mobile users are provided by IMS (IP Multimedia Subsystem), which is built on EPC (Evolved Packet Core) / 5GC. The core feature of IMS is "access independence", that is, user terminals can support accessing IMS built on EPC / 5GC through various access methods, such as 5G NR, LTE, and WLAN.

[0046] Currently, the handover mechanisms defined in the 3GPP specifications are all between two access methods, and the handover between 5G NR and LTE is controlled by the network side, while the handover between 5G NR / LTE and WiFi is controlled by the terminal side.

[0047] When a user terminal simultaneously supports IMS services on these three access methods, that is, when the terminal simultaneously supports three voice services: VoNR / VoLTE / VoWiFi, problems may occur in the following handover scenarios: The terminal was originally camped on NR (or LTE). If the signal of the source network it is currently camped on becomes increasingly weak, the network side may initiate a handover process to the target network LTE (or NR). At the same time, the terminal side may also initiate a handover process to the target network WiFi. This will result in a waste of resource allocation for one side when switching to the target network and a decrease in the handover success rate.

[0048] In view of the above problems, embodiments of this application provide a method, apparatus and device for implementing handover between multiple access types, so as to enable handover from the source network to only one target network at the same time in scenarios that support multiple network types of access, when the source network does not meet the requirements and handover to multiple target networks is supported at the same time, by using preset handover rules to avoid simultaneously initiating handover to multiple target networks, thereby improving the handover success rate and reducing resource allocation waste.

[0049] In the embodiments of this application, a terminal can refer to a UE, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user equipment. An access terminal can be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, and a mobile station in a 5G network or a subscription device in a future evolved Public Land Mobile Network (PLMN) network, etc.

[0050] In the embodiments of this application, the network-side equipment can be a next-generation base station (gNB) in a 5G system, a base station (BTS) in a Global System of Mobile communication (GSM) system or a Code Division Multiple Access (CDMA) system, a base station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) system, or an evolved base station (eNB or eNodeB) in a Long Term Evolution (LTE) system, etc.

[0051] like Figure 1 The diagram shown is a flowchart illustrating a method for switching between multiple access points according to an embodiment of this application. The method includes:

[0052] Step 11: When the access network handover conditions are met, measure the signal quality of the multiple networks to be accessed;

[0053] Specifically, if the signal quality of the source network currently hosted by the terminal does not meet the set requirements, thus failing to meet the current service needs, and the access network switching conditions are determined to be met, it is necessary to measure the signal quality of multiple networks to be accessed in order to switch to the target network with better signal quality so that the service needs can be met.

[0054] For example, if the source network currently hosted by the terminal is an LTE network, but the current network quality cannot meet the service requirements of the VoLTE (voice service based on LTE network) currently initiated by the terminal, it is necessary to measure the signal quality of multiple networks such as NR and WLAN to be accessed, so as to stop initiating VoLTE and switch to the target network with better signal quality to initiate voice services such as VoNR / VoWiFi, so that the voice service requirements can be met.

[0055] As a feasible implementation method, when the access network handover conditions are met, the signal quality of the multiple networks to be accessed is measured, including:

[0056] When the signal quality of the current access network is determined to be below the first threshold, a report is sent to the network side.

[0057] Receive the command from the network side to measure the signal quality of the first network, measure the signal quality of the first network to be accessed, and measure the signal quality of the second network to be accessed;

[0058] The first network is the network to be accessed that is triggered by the network side to perform the access handover, and the second network is the network to be accessed that is triggered by the terminal to perform the access handover.

[0059] It should be noted that, based on a predefined network quality measurement method, the signal quality of the current source network is measured, and when the signal quality parameter of the source network is detected to be lower than a first threshold, it is determined that the access network handover conditions are met.

[0060] In one or more embodiments, different network quality measurement methods are preset for different types of access networks. For example, if the source network where the current terminal is located is NR / LTE, the access network handover conditions are determined by measuring the Reference Signal Received Power (RSRP); if the source network where the current terminal is located is WLAN, the access network handover conditions are determined by measuring the Signal Strength Indicator (RSSI).

[0061] It should be noted that the signal quality parameters selected when determining whether the access network handover conditions are met in the embodiments of this application are not limited to RSRP and RSSI, but can also be other parameters or combinations of parameters that can reflect network quality. This application does not limit them.

[0062] Step 12: Based on the signal quality measurement results, perform a handover to a first target network that meets the handover requirements;

[0063] In one or more embodiments, after measuring the signal quality of multiple networks to be accessed, there may be multiple networks whose signal quality meets the handover requirements and can be used as target networks for source network handover. Therefore, in order to initiate only one handover from the source network to a target network at the same time, and to avoid initiating handover to multiple target networks at the same time, which would lead to a decrease in handover success rate and waste of resource allocation, it is necessary to set handover rules to implement handover to a first target network that meets the handover requirements based on the signal quality measurement results.

[0064] As a feasible implementation method, based on signal quality measurement results, a handover to a first target network that meets the handover requirements is performed, including:

[0065] Based on the signal quality measurement results, the first target network whose signal quality meets the handover requirements is accessed earliest.

[0066] It should be noted that the aforementioned first target network can be the network to be accessed that was first detected to have signal quality exceeding a preset handover threshold in time, or it can be a first target network selected from the networks to be accessed whose signal quality exceeds the preset handover threshold under other screening conditions. This application does not limit this.

[0067] In one or more embodiments, when performing a handover to a first target network that meets the handover requirements, the object initiating the handover is different depending on the type of the first target network to be accessed.

[0068] As one possible implementation, performing a handover to a first target network that meets the handover requirements includes:

[0069] When the first target network is determined to be the network to be accessed that triggers an access handover on the network side, the handover to the first target network is initiated by the network side; or

[0070] When the first target network is determined to be the network to be accessed by the terminal to trigger the access handover, the terminal initiates the handover to the first target network.

[0071] For example, if a switch from LTE to NR is required, and the NR access handover needs to be triggered by the network side, the terminal needs to report to the network side that the NR meets the handover requirements, and the network side initiates the handover from LTE to NR; if a switch from LTE to WiFi is required, and the WiFi access handover needs to be triggered by the terminal, the terminal initiates the handover from LTE to WiFi.

[0072] Step 13: Before successfully accessing the first target network, if the second target network is found to meet the handover requirements, then prohibit access to the second target network or access the second target network and stop accessing the first target network.

[0073] In one or more embodiments, before the handover from the source network to the first target network is completed, the signal quality of the multiple networks to be accessed and the signal quality of the current source network are still measured. Therefore, before the handover from the source network to the first target network is completed, based on the signal quality measurement results, it may be measured that the second target network meets the handover requirements, or the signal quality of the current source network becomes worse. For example, the signal quality of the current source network is lower than a second threshold, wherein the second threshold is lower than the aforementioned first threshold.

[0074] In one or more embodiments, before the handover from the source network to the first target network is completed, if the second target network is measured to meet the handover requirements, it is determined whether to access the second target network and stop accessing the first target network according to a preset handover rule.

[0075] As one possible implementation, accessing the second target network and stopping access to the first target network includes:

[0076] If it is determined that the priority of the second target network is higher than that of the first target network, access to the second target network is granted and access to the first target network is stopped.

[0077] As a possible implementation method, blocking access to the second target network includes:

[0078] If the priority of the second target network is determined to be lower than that of the first target network, and the signal quality of the currently accessed network has not fallen below the second threshold, access to the second target network is prohibited.

[0079] In one or more embodiments, when performing a handover to a second target network that meets the handover requirements, the object initiating the handover is different depending on the type of the second target network to be accessed.

[0080] As one possible implementation, accessing the second target network and stopping access to the first target network includes:

[0081] When the second target network is determined to be the network to be accessed that the network side triggers to perform access handover, the signal quality of the second target network is reported to the network side to meet the handover requirements. The network side then initiates the handover to the second target network and stops the handover to the first target network.

[0082] When the second target network is determined to be the network to be accessed by the terminal to trigger the access handover, the terminal initiates the handover to the second target network and stops the handover to the first target network.

[0083] In one or more embodiments, if the second target network meets the switching requirements and the signal quality of the current source network is measured to be lower than a second threshold before the handover from the source network to the first target network is completed, it indicates that the signal quality of the current source network is so bad that a handover is necessary. At the same time, since the handover from the source network to the first target network has not yet been successful, it is necessary to access the second target network and stop accessing the first target network.

[0084] As one possible implementation, accessing the second target network and stopping access to the first target network includes:

[0085] If the signal quality of the currently accessed network is measured to be lower than the second threshold, and the handover to the first target network has not yet been successful, the system accesses the second target network and stops accessing the first target network. The second threshold is lower than the first threshold.

[0086] like Figure 2 The diagram illustrates the switching rules provided in this application's embodiments. Figure 1 This includes the following steps:

[0087] Step 21: Before the handover from the source network to the first target network is completed, continue to measure the signal quality of the multiple networks to be accessed, and execute step 22 when the second target network is measured to meet the handover requirements;

[0088] Step 22: Determine whether the priority of the second target network is higher than that of the first target network. If yes, proceed to step 23; otherwise, proceed to step 24.

[0089] Step 23: Connect to the second target network and stop connecting to the first target network;

[0090] Step 24: Block access to the second target network.

[0091] like Figure 3 The diagram illustrates the switching rules provided in this application's embodiments. Figure 2 This includes the following steps:

[0092] Step 31: Before the handover from the source network to the first target network is completed, continue to measure the signal quality of the multiple networks to be accessed and the signal quality of the current source network, and execute step 32 when the second target network is measured to meet the handover requirements.

[0093] Step 32: Determine whether the priority of the second target network is higher than that of the first target network. If yes, proceed to step 33; otherwise, proceed to step 34.

[0094] Step 33: Connect to the second target network and stop connecting to the first target network;

[0095] Step 34: Block access to the second target network and proceed to step 35;

[0096] Step 35: Determine whether the signal quality of the currently accessed network is lower than the second threshold. If yes, proceed to step 33; otherwise, proceed to step 34.

[0097] It should be noted that the second threshold mentioned above is lower than the first threshold.

[0098] Based on the method for switching between multiple access networks provided in the embodiments of this application, in service scenarios that support multiple network types of access, when the source network does not meet the service requirements and simultaneously supports switching to multiple target networks, a preset switching rule is used to ensure that only one switching from the source network to a target network is initiated at the same time, avoiding simultaneous switching to multiple target networks, thereby improving the switching success rate and reducing resource allocation waste.

[0099] The following describes two specific implementation methods for the method of switching between multiple access points as described in the foregoing embodiments.

[0100] like Figure 4 The diagram shown is an access handover schematic diagram when the first target network is triggered by the network side in an embodiment of this application, including the following steps:

[0101] Step 41: The terminal initiates a VoNR call on the NR access;

[0102] Step 42: During the movement, the quality of the NR signal gradually decreases, and after the NR signal is measured to be below the first threshold, the terminal reports to the network side and continues to measure the NR signal.

[0103] Step 43: Receive the command from the network side to measure the signal quality of the LTE network, measure the signal quality of the LTE network to be accessed, and measure the signal quality of the WiFi to be accessed.

[0104] Step 44: First, if the signal quality of the LTE network is measured to be higher than the handover threshold, report it to the network side and proceed to step 45.

[0105] It should be noted that the switching threshold in step 44 is a threshold that is pre-set for the LTE network access type.

[0106] Step 45: The network side initiates a handover to the LTE network, and if the WiFi signal quality is measured to be higher than the handover threshold before the handover is completed, proceed to step 46.

[0107] It should be noted that the switching threshold in step 45 is a threshold that is pre-set for the WiFi access type.

[0108] Step 46: Determine whether WiFi has a higher priority than LTE network. If yes, proceed to step 47; otherwise, proceed to step 48.

[0109] Step 47: The terminal initiates WiFi access and stops accessing the LTE network;

[0110] Step 48: Disable WiFi access and proceed to step 49;

[0111] Step 49: Determine whether the signal quality of the current NR access is lower than the second threshold. If yes, proceed to step 47; otherwise, proceed to step 48. The second threshold is lower than the first threshold.

[0112] like Figure 5 The diagram shown is an access handover illustration when a terminal triggers an access handover in the first target network provided in this application embodiment, including the following steps:

[0113] Step 51: The terminal initiates a VoNR call on the NR access;

[0114] Step 52: During the movement, the quality of the NR signal of the terminal gradually decreases, and after the NR signal is measured to be lower than the first threshold, the terminal reports to the network side and continues to measure the NR signal.

[0115] Step 53: Receive the command from the network side to measure the signal quality of the LTE network, measure the signal quality of the LTE network to be accessed, and measure the signal quality of the WiFi to be accessed.

[0116] Step 54: First, measure the WiFi signal quality to find it is higher than the handover threshold, then proceed to step 55;

[0117] It should be noted that the switching threshold in step 54 is a threshold pre-set for the WiFi access type. In step 55, the terminal initiates a handover to WiFi, and if the signal quality of the LTE network is measured to be higher than the handover threshold before the handover is completed, step 56 is executed.

[0118] It should be noted that the switching threshold in step 55 is a threshold that is pre-set for the LTE network access type.

[0119] Step 56: Determine whether the priority of the LTE network is higher than that of WiFi. If yes, proceed to step 57; otherwise, proceed to step 58.

[0120] Step 57: The network side initiates access to the LTE network and stops accessing WiFi;

[0121] Step 58: Block access to the LTE network and proceed to step 59;

[0122] Step 59: Determine whether the signal quality of the current NR access is lower than the second threshold. If yes, proceed to step 57; otherwise, proceed to step 58. The second threshold is lower than the first threshold.

[0123] Based on the same inventive concept, embodiments of this application also provide an apparatus, such as... Figure 6 As shown, the device includes:

[0124] Measurement module 601 is used to measure the signal quality of multiple networks to be accessed when the access network switching conditions are met.

[0128] The first network is the network to be accessed that is triggered by the network side to perform the access handover, and the second network is the network to be accessed that is triggered by the terminal to perform the access handover.

[0138] When the second target network is determined to be the network to be accessed that the network side triggers to perform access handover, the signal quality of the second target network is reported to the network side to meet the handover requirements. The network side then initiates the handover to the second target network and stops the handover to the first target network.

[0139] When the second target network is determined to be the network to be accessed by the terminal to trigger the access handover, the handover to the second target network is initiated and the handover to the first target network is stopped.

[0140] In one or more embodiments, the second switching module is specifically used for:

[0141] When the signal quality of the currently accessed network is measured to be lower than the second threshold, access to the second target network is established and access to the first target network is stopped. The second threshold is lower than the first threshold.

[0142] In one or more embodiments, the second switching module is specifically used for:

[0143] If the priority of the second target network is determined to be lower than that of the first target network, access to the second target network is prohibited.
