Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Wherein the described embodiments are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the 4G/5G age, voice/video services of mobile users are provided by IMS (IP Multimedia Subsystem ) that is structured above EPC (Evolved Packet Core, packet core evolution)/5 GC, the core feature of which is "access independent", i.e. a user terminal can support access to IMS structured above EPC/5GC through multiple access means, such as 5G NR, LTE, WLAN.
The switching mechanism defined in the 3GPP specification is between two access modes at present, and the switching between 5G NR and LTE is controlled by a network side, and the switching between 5G NR/LTE and WiFi is controlled by a terminal side.
When a user terminal supports IMS services provided on these 3 accesses simultaneously, i.e. the terminal supports three voice services, voNR/VoLTE/VoWiFi simultaneously, problems may occur in the following handover scenarios: if the signal of the current residing source network is worse, the network side may initiate a process of switching to the target network LTE (or NR), and at the same time, the terminal side may initiate a process of switching to the target network WiFi, which may result in waste of resource allocation of one party for switching to the target network and decrease of the switching success rate.
In view of the above problems, embodiments of the present application provide a method, an apparatus, and a device for implementing handover between multiple accesses, so as to implement that when a source network does not meet a requirement and simultaneously supports handover to multiple target networks in a scenario of supporting multiple network types of access, only the source network initiates handover to one target network at the same time through a preset handover rule, thereby avoiding simultaneous initiation of handover to multiple target networks, and improving handover success rate and reducing resource allocation waste.
In the embodiment of the present application, a terminal may refer to a UE, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user apparatus. An access terminal may be a cellular telephone, a cordless telephone, a session initiation protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a personal digital assistant (Personal Digital Assistant, PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, and a mobile station in a 5G network or subscription device in a future-evolving public land mobile network (Public Land Mobile Network, PLMN) network, etc.
In the embodiment of the present application, the network side device may be a next generation base station (generation Node B, gNB) in a 5G system, may be a base station (Base Transceiver Station, BTS) in a global system for mobile communications (Global System of Mobile communication, GSM) system or a code division multiple access (Code Division Multiple Access, CDMA), may also be a base station (NodeB, NB) in a wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) system, may also be an evolved base station (Evolutional Node B, eNB or eNodeB) in a long term evolution (Long Term Evolution, LTE) system, and so on.
As shown in fig. 1, a flow chart of a method for implementing handoff between multiple accesses according to an embodiment of the present application is shown, where the method includes:
step 11, measuring signal quality of a plurality of networks to be accessed when the access network switching condition is determined to be satisfied;
specifically, if the signal quality of the source network where the terminal currently resides cannot meet the set requirement, and thus cannot meet the current service requirement, determining that the access network switching condition is met, and measuring the signal quality of a plurality of networks to be accessed is needed to switch to a target network with better signal quality, so that the service requirement is met.
For example, if the source network where the terminal currently resides is an LTE network, but the current network quality cannot meet the service requirement of the VoLTE (voice service based on the LTE network) currently initiated by the terminal, the signal quality of multiple networks to be accessed, such as NR, WLAN, needs to be measured to stop initiating the VoLTE, and the voice service such as VoNR/VoWiFi is initiated under the target network with better signal quality, so that the voice service requirement is met.
As a possible implementation manner, when determining that the access network handover condition is satisfied, measuring signal quality of a plurality of networks to be accessed includes:
reporting the signal quality of the current access network to a network side when the signal quality is determined to be lower than a first threshold;
receiving a command for measuring signal quality of a first network sent by a network side, measuring the signal quality of the first network to be accessed, and measuring the signal quality of a second network to be accessed;
the first network is a network to be accessed, which is triggered by a network side to execute access switching, and the second network is a network to be accessed, which is triggered by a terminal to execute access switching.
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 the first threshold, it is determined that the access network switching condition is satisfied.
In one or more embodiments, different network quality measurement methods are preset for different types of access networks, and if the source network where the current terminal is located is NR/LTE, by measuring reference signal received power RSRP, it is determined whether the access network switching condition is currently satisfied; if the source network where the current terminal is located is WLAN, determining whether the current access network switching condition is met by measuring the signal strength RSSI.
It should be noted that, when determining whether the access network switching condition is currently satisfied, the signal quality parameters selected in the embodiment of the present application are not limited to RSRP and RSSI, but may be other parameters or combinations of parameters that may embody the network quality.
Step 12, according to the signal quality measurement result, performing handover to a first target network meeting the handover requirement;
in one or more embodiments, after measuring signal quality of multiple networks to be accessed, there may be multiple networks to be accessed whose signal quality meets a handover requirement as target networks for source network handover, so, in order to make a handover from a source network to only one target network be initiated at a time, handover success rate reduction and resource allocation waste caused by simultaneous initiation of handover to multiple target networks are avoided, a handover rule needs to be set, and handover to a first target network meeting the handover requirement is performed according to a signal quality measurement result.
As a possible implementation manner, performing handover to a first target network that meets a handover requirement according to a signal quality measurement result, including:
and accessing a first target network with earliest detected signal quality meeting the switching requirement according to the signal quality measurement result.
It should be noted that the first target network may be a network to be accessed, in which the signal quality detected at the earliest time exceeds a preset switching threshold, or may be a first target network selected from the networks to be accessed, in which the signal quality exceeds the preset switching threshold, under other screening conditions.
In one or more embodiments, when performing a handover to a first target network that meets the handover requirement, the object that initiates the handover is different according to the type of the first target network to be accessed.
As a possible implementation manner, performing handover to a first target network that meets a handover requirement includes:
when the first target network is determined to be a network to be accessed for triggering and executing access switching by a network side, the network side initiates switching to the first target network; or alternatively
And when the first target network is determined to be the network to be accessed for triggering the execution of access switching by the terminal, the terminal initiates the switching to the first target network.
For example, if the handover from LTE to NR is currently required, and the NR needs to be triggered by the network side to perform the access handover, the terminal needs to report to the network side that the NR meets the handover requirement, and the network side initiates the handover from LTE to NR; if the switching from LTE to WiFi is needed currently, and the WiFi needs to be triggered by the terminal to execute the access switching, the terminal initiates the switching from LTE to WiFi.
And step 13, when the second target network is measured to meet the switching requirement before the first target network is successfully accessed, the second target network is forbidden to be accessed or the second target network is accessed and the first target network is stopped to be accessed.
In one or more embodiments, the signal quality of the plurality of networks to be accessed and the signal quality of the current source network are still measured before the handover from the source network to the first target network is completed, so that before the handover from the source network to the first target network is completed, according to the signal quality measurement result, it may be measured that the second target network meets the handover requirement, or the signal quality of the current source network becomes worse, where the signal quality of the current source network is lower than a second threshold, which is lower than the first threshold.
In one or more embodiments, before the handover from the source network to the first target network is completed, when the second target network is measured to meet the handover requirement, determining whether to access the second target network and stopping accessing the first target network according to a preset handover rule.
As a possible implementation manner, accessing the second target network and stopping accessing the first target network includes:
and when the priority of the second target network is higher than that of the first target network, accessing the second target network and stopping accessing the first target network.
As a possible implementation manner, prohibiting access to the second target network includes:
and when 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 current access network is not lower than a second threshold, prohibiting access to the second target network.
In one or more embodiments, when performing a handover to a second target network that meets the handover requirement, the object that initiates the handover is different depending on the type of second target network to be accessed.
As a possible implementation manner, accessing the second target network and stopping accessing the first target network includes:
when the second target network is determined to be a network to be accessed for triggering and executing access switching by a network side, reporting that the signal quality of the second target network at the network side meets the switching requirement, and initiating switching to the second target network and stopping switching to the first target network by the network side;
when the second target network is determined to be the network to be accessed for triggering the access switching by the terminal, the terminal initiates the switching to the second target network and stops the switching to the first target network.
In one or more embodiments, before the handover from the source network to the first target network is completed, when the second target network is measured to meet the handover requirement and the signal quality of the current source network is measured to be lower than a second threshold, it is indicated that the signal quality of the current source network is poor enough to be necessary to be handed over, and meanwhile, since the handover from the source network to the first target network is still unsuccessful, it is necessary to access the second target network and stop accessing the first target network.
As a possible implementation manner, accessing the second target network and stopping accessing the first target network includes:
and when the signal quality of the current access network is measured to be lower than a second threshold and the handover to the first target network is not successful yet, accessing the second target network and stopping accessing the first target network, wherein the second threshold is lower than the first threshold.
As shown in fig. 2, a first switching rule schematic diagram provided by an embodiment of the present application includes the following steps:
step 21, before the switching from the source network to the first target network is completed, the signal quality of a plurality of networks to be accessed is still measured, and step 22 is executed when the second target network is measured to meet the switching requirement;
step 22, judging whether the priority of the second target network is higher than that of the first target network, if yes, executing step 23, otherwise, executing step 24;
step 23, accessing the second target network and stopping accessing the first target network;
and step 24, prohibiting access to the second target network.
As shown in fig. 3, a second switching rule diagram provided by an embodiment of the present application includes the following steps:
step 31, before the handover from the source network to the first target network is completed, the signal quality of a plurality of networks to be accessed and the signal quality of the current source network are still measured, and when the second target network is measured to meet the handover requirement, step 32 is executed;
step 32, judging whether the priority of the second target network is higher than that of the first target network, if yes, executing step 33, otherwise, executing step 34;
step 33, accessing the second target network and stopping accessing the first target network;
step 34, prohibiting access to the second target network and executing step 35;
step 35, determining whether the signal quality of the current access network is lower than a second threshold, if yes, executing step 33, and if not, executing step 34.
It should be noted that the second threshold is lower than the first threshold.
Based on the method for realizing the switching between multiple accesses provided by the embodiment of the application, under the service scene supporting multiple network types of access, when the source network does not meet the service requirement and simultaneously supports the switching to multiple target networks, the switching from the source network to one target network is only initiated at the same time through the preset switching rule, the switching to multiple target networks is prevented from being initiated at the same time, the switching success rate can be improved, and the resource allocation waste can be reduced.
