Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
References herein to "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.
In the related art, UAC inspection is introduced for various services 5G. The UAC check aims to more reasonably use network resources and relieve network congestion under the condition of increasing 5G traffic in the initial stage of networking and later. Before initiating service, the UE first decides whether the access can be initiated, if not, the UE does not initiate the access service and waits for relief, thereby achieving the effect of limiting network load. However, at the time of UAC inspection, there may be a case where traffic always initiates failure under the 5G network in the connected state.
Schematically, as shown in fig. 1, a flowchart of a service reject procedure by UAC in the related art is shown.
When a Non-Access Stratum (NAS) is in a signaling connection state and a service which is initiated successfully exists at a UE side, an application layer initiates a new service to the NAS, a mobility management (Mobility Management, MM) layer in the NAS maps to a corresponding Access category (Access category) and an Access identifier (Access id) according to the service type of the new initiated service, and initiates an Access request (MM_SEND_RRC_DATA_REQ) to a radio resource control (Radio Resource Control, RRC) layer, and after receiving the Access request, the RRC layer performs UAC check on the Access category and the Access id based on broadcast information in a system message block 1 (System Information Block 1, SIB 1). If the UAC check is not passed, access is not allowed, the RRC layer SENDs a reject access response (MM_SEND_RRC_DATA_REJ) to the MM layer and starts a corresponding inhibit (bar) timer. Before the MM layer receives the allowed access indication, the application layer is refused to initiate the same type of service until the bar timer expires or the bar ending condition is met, and the RRC layer SENDs the allowed access indication (rrc_send_uac_ ALLEVIATE _ind) to the MM layer. In abnormal situations, the service can be continuously in a non-initiation state and can only wait for network recovery.
In addition to the UAC check, the protocol data unit (Protocol Data Unit, PDU) session management procedure in 5G networks introduces congestion control of network slices, when session traffic for the corresponding slice cannot be initiated during the network slice congestion control timer running.
Schematically, a flow chart of a network slice congestion control procedure is shown in fig. 2.
When the NAS is in a signaling connection state and a service initiated successfully exists on the UE side, the application layer initiates a new service to the session management (Session Management, SM) layer, and the SM layer sends a related session procedure to the MM layer, requesting to establish a session for the new service. The MM layer sends a corresponding request to a network side, when network resources are tense, the network side refuses SM session, sends a refusing SM session response and a value of a back off timer to the MM layer, and sends the refusing session response and the value of the back off timer to the SM layer after receiving the refusing session response and the value of the back off timer, and the SM layer obtains the back off value and the type, wherein the type comprises a data network name (Data Network Name, DNN) and a network slice (network slice). The SM layer can learn the congestion rejection reason according to the obtained type of the backup off timer, and starts a corresponding timer, and during the running period of the timer, the related services of the UE initiating DNN or network slices which are the same as the services can be rejected by the SM layer until the timer is overtime, and the services of the same type can be initiated. When the network resources are tense, the same type of service is continuously refused, and the UE can only passively wait for network recovery.
From the above UAC check and congestion control process of the network slice, it can be seen that when a new initiated service is rejected by the UAC or is rejected due to shortage of network resources, the service of the same type cannot be initiated all the time during the rejection period, and only the network recovery can be waited, so that the service cannot be initiated for a long time, and normal use of the UE is affected.
In the embodiment of the application, by setting the priority for the service of the application layer and indicating the service network type of the network system supported by the service, when the first service is initiated under the first network, whether the network switching condition is met is judged according to the service priority and the service network type, and when the condition is met, the network is switched to the second network of a different system from the first network, so that the first service can be successfully initiated under the second network, the problem that the service cannot be initiated due to the fact that the service is in the first network for a long time is avoided, and the success rate of service initiation is improved.
Referring to fig. 3, a flowchart of a service initiation method according to an exemplary embodiment of the present application is shown. The present embodiment is described taking the method performed by the UE as an example, and the process includes the following steps:
In one possible implementation, the first service is initiated by the application layer of the UE towards the NAS, the UE is in the first network mode when initiating, the NAS is in a signaling connection state, and there is a successfully initiated service.
In one illustrative example, a UE initiates a first service under a 5G network.
Alternatively, when the first service is initiated, the initiation request may be rejected due to UAC check or network congestion, so that the first service is in an uninitiated state.
In one possible implementation manner, the UE first obtains an initiation state of the first service, and when the first service is in an unable initiation state, that is, when the first service fails to be initiated, the NAS of the UE obtains service information of the first service and second service, where the second service is a service successfully initiated under the first network, and the UE side includes at least one second service, and the service information includes a service priority and a service network type.
In the embodiment of the application, the service priority is an index for measuring the importance degree of the service, and when the service priority is higher, the higher the importance degree of the service is indicated; the service network type is determined according to network indexes of different networks and network requirements of different services, and is used for indicating network modes supported by the services.
Alternatively, the service priority is divided into at least three levels, for example, different services may be divided into 5 levels 1, 2, 3, 4, 5, and the 5 th level is the highest service priority. The embodiment of the application does not limit the number of service priority levels.
Optionally, the service network types may be divided into a first service network type and a second service network type, where the service belonging to the first service network type supports a first network system and a second network system, and the service belonging to the second service network type supports the first network system and does not support the second network system. For example, traffic may be classified into traffic supporting a 4G/5G network and traffic supporting only a 5G network.
The following embodiments will be described in detail with respect to a manner of determining service priority and service network type.
Step 303, switching from the first network to the second network in response to the first service information and the second service information satisfying the network switching condition, wherein the second network adopts a second network system, and the first network system is different from the second network system.
In a possible implementation manner, the UE detects whether the network switching condition is satisfied according to the acquired first service information and second service information, and when both the service priority and the service network type satisfy the network switching condition, the UE notifies the network side to perform network switching, and switches the first network to a second network adopting the second network system. The second network system is a network system supported by the first service.
In one illustrative example, when a network handover condition is satisfied, the terminal is handed over from the current 5G network to the 4G network.
In one possible implementation, when the network switches to the second network, the first service is reinitiated under the network, at which point the first service may be successfully initiated under the second network.
Illustratively, when the first service is a game data service, the first service is failed to initiate under the 5G network due to UAC inspection or network slice congestion control. At this time, the UE detects whether the priority of the game data service and the type of the service network meet the network switching condition, and if so, the UE notifies the network side to switch the 5G network to the 4G network, and after the network switching, when the game data service is initiated under the 4G network, the service can be successfully initiated under the 4G network because the 4G network does not include UAC inspection and congestion control of the network slice.
It should be noted that, for the second service that has been successfully initiated, the UE cooperates with the network side to switch the second service from the first network to the second network, so that the second service is continued under the second network, which is not limited in the embodiment of the present application.
In summary, in the embodiment of the present application, by setting the service priority for the service and indicating the service network type of the network system supported by the service, when the first service is initiated under the first network, based on the service priority and the service network type of the first service and the second service that is successfully initiated, it is determined whether the network switching condition is satisfied, so that when the network switching condition is satisfied, the network is switched to the second network that adopts a different network system from the first network, and then the first service is initiated under the second network, thereby avoiding the problem that the service is frequently initiated to fail due to the network cause, and being helpful to improve the success rate of service initiation.
In relation to the manner of determining the service priority, in one possible implementation, the service priority is determined according to service usage requirements.
The service usage requirement is a service attribute determined according to user settings or user usage habits, for example, for user a, the service usage requirement of the game service is set to the highest level, and for user B, the service usage requirement of the video service is set to the highest level; alternatively, the service use requirement of the game service having the highest frequency of use is set to the highest level based on the service use frequency of the user a, and the service use requirement of the video service having the highest frequency of use is set to the highest level based on the service use frequency of the user B.
In some embodiments, the UE determines the service usage requirements of the user for different services by counting the service usage records of the user, thereby determining the priorities corresponding to the various services. Illustratively, the service priority of the user a may be as shown in table one:
list one
| Service | Service priority |
| Game data service | 5 |
| Voice call service | 4 |
| Video service | 3 |
| Short message service | 1 |
The game data service is the highest service priority, and the short message service is the lowest service priority.
Regarding the manner of determining the service network type, in one possible implementation, the service network type is determined according to network metrics of different network formats and network requirements of different services. When the network index meets the network requirement of the service, the network system is determined as the network system supported by the service, and the service network type to which the service belongs is further determined according to the set of the network systems supported by the service.
Optionally, the network indicator comprises a network transmission rate indicator, and the network requirement comprises a network transmission rate requirement. For example, the uplink rate of the 5G network can reach 100Mbps, the downlink rate can reach 1Gbps, the uplink rate of the 4G network can reach 20Mbps, and the downlink rate can reach 100Mbps. When the network transmission rate requirement of the service exceeds the network transmission rate index of the 4G network, the service is divided into service network types supporting only the 5G network, and when the network transmission rate requirement of the service is within the network transmission rate index of the 4G network, the service is divided into service network types supporting the 4G/5G network.
Optionally, the network indicator further includes a network delay indicator, and the network requirement includes a network delay requirement. For example, the 5G network delay is 5-10ms and the 4G network delay is 50-100ms. When the network delay requirement of the service is high delay requirement, if the service is driven automatically, dividing the service into services only supporting a 5G network; when the network delay requirement of the service is low delay requirement, for example, a short message service, the service is divided into service network types supporting a 4G/5G network.
In some embodiments, the UE may determine the service network type based on two dimensions of the network transmission rate and the network delay at the same time, or the UE may determine the service network type based on the service priority by combining the network transmission rate and the network delay, which is not limited in this embodiment.
Schematically, as shown in fig. 4, the application layer of the UE determines service priorities of the services according to service usage requirements, and sends a service priority setting request to the NAS, and after receiving the request, the NAS determines service network types to which each service belongs based on the service priorities of the services, service types (such as IP multimedia subsystem (IP Multimedia Subsystem, IMS), short Message Service (SMS)), qoS parameters of PDU sessions, and network slicing parameters, so as to store correspondence among the services, service priorities, and service network types, so as to determine the service priorities and service network types corresponding to the services. After the service network type is determined, the NAS sends a service priority setting completion response to the application layer.
Referring to fig. 5, a flowchart of a service initiation method according to another exemplary embodiment of the present application is shown. The present embodiment is described taking the method performed by the UE as an example, and the process includes the following steps:
in step 501, a first service is initiated under a first network, where the first network adopts a first network system.
In one possible implementation, under the first network, the application layer sends a first service initiation request to the NAS, and if the first service initiation fails, step 502 is performed.
In one possible implementation, when the first service is initiated to fail due to UAC check or network congestion control, the application layer subsequently initiates the first service and is rejected by the NAS, and as the number of service initiation failures increases, the NAS continuously updates the number of failure.
In step 503, the first service information and the second service information are acquired in response to the failure times reaching the time threshold.
In a possible implementation manner, when the number of times of the first service initiation failure reaches the number threshold, it indicates that the first service is in an unsuccessful state for a long time, at this time, in order to avoid that the important service cannot be initiated successfully for a long time and affect normal use, the NAS acquires first service information of the first service and second service information of the second service, so as to determine whether network handover is required based on the first service information and the second service information, so as to improve probability of successful service initiation. The number of times threshold may be a preset value, for example, the number of times threshold may be 3 times.
Optionally, the first service information includes a first service priority and a first service network type, and the second service information includes a second service priority and a second service network type. In some possible embodiments, the NAS obtains, according to the service identifier of the service, the service priority and the service network type corresponding to each of the first and second services from a correspondence among the service, the service priority and the service network type.
Illustratively, the first service that is initiated currently is service a, and the second service that is initiated successfully under the 5G network includes service B and service C, where NAS obtains that the first service priority of service a is 5, the first service network type is 4G/5G network, the second service priority of service B is 3, the second service network type is 4G/5G network, the second service priority of service C is 4, and the second service network type is 4G/5G network.
In step 504, in response to the first service priority being higher than the second service priority and the first service network type being the target service network type, it is determined that the network switching condition is satisfied, and a switch is made from the first network to the second network.
In the embodiment of the application, the network switching condition is determined based on the service priority and the service network type. The service priority indicates the importance degree of the service, and if the second service priority is higher than the first service priority, the network may be switched to affect the second service which is more important, so in order to reduce the influence caused by the network switching, it is necessary to determine whether to perform the network switching based on the service priority. In addition, some services have special requirements on network formats, in order to ensure that after network switching, the first service can be normally initiated and executed under the switched network, and whether the first service supports other network formats needs to be determined according to the service network type.
In one possible implementation, after the NAS acquires the first service information and the second service information, the NAS detects whether the first service priority is higher than each second service priority, determines that the priority condition is satisfied when the first service priority is higher than each second service priority, and further detects whether the first service network type satisfies the network type condition. When the first service network type is a target service network type, the NAS determines that the first service meets the network type condition, and the target service network type refers to that the service supports a first network system and a second network system. When the priority condition and the network service network type condition are satisfied, the NAS determines that the first service satisfies the network switching condition, and further triggers the switching from the first network to the second network.
Optionally, the service belonging to the target service network type supports a 4G/5G network, and correspondingly, when the network switching condition is satisfied, the NAS triggers switching from the 5G network to the 4G network.
In combination with the example in the above steps, in the 5G network, because of UAC inspection or network congestion, service a fails to be initiated and continues to be unable to be initiated successfully, at this time, because the first service priority of service a is 5-level, which is higher than the second service priorities of service B and service C, and the service network type of service a is 4G/5G network, the network switching condition is satisfied, and the network can be switched from 5G to 4G, so that service a is initiated successfully in the 4G network.
For the procedure of network handover, this step may optionally comprise the following sub-steps.
1. Carrying out cell measurement on the neighbor cells to obtain measurement results, wherein the neighbor cells adopt a second network;
in one possible implementation, when the network switching condition is met, the NAS sends a network switching request to the RRC layer, and the RRC layer measures a current serving cell and a neighboring cell according to the network switching request and obtains a measurement result, where the RRC layer performs heterogeneous measurement on the serving cell and the neighboring cell that adopt different network systems, the serving cell adopts a first network of a first network system, and the neighboring cell adopts a second network of a second network system.
Illustratively, the serving cell where the UE is currently located is a 5G cell, and when the network handover condition is satisfied, the UE measures the 5G cell and the neighboring cell using the 4G network at the same time, so as to obtain a measurement result.
2. Generating a first measurement report according to the measurement result in response to the existence of the neighbor cell meeting the handover condition;
in one possible implementation, the first measurement report is generated when the RRC layer measures that the quality of service of the neighbor cell employing the second network is higher than the current serving cell, i.e. the handover condition is met.
3. The method comprises the steps that a first measurement report is sent to a network side, and the network side is used for switching a terminal from a serving cell to a neighbor cell according to the first measurement report;
in one possible implementation, the RRC layer sends a first measurement report to the network layer, and after the network side receives the first measurement report, triggers handover of the UE from the serving cell to the neighbor cell, and sends a cell handover instruction to the UE. The cell switching instruction comprises a neighbor cell identifier, and the UE is switched to a specified neighbor cell according to the neighbor cell identifier.
4. And switching from the service cell to the neighbor cell according to a cell switching instruction sent by the network side.
In one possible implementation, after receiving the instruction of cell switching, the network side switches the UE from the serving cell to the neighboring cell, so as to implement switching from the first network to the second network.
In one possible scenario, the measurement result of the RRC layer on the neighbor cell indicates that the quality of service of the neighbor cell is lower than that of the current serving cell, and at this time, if the measurement report is sent to the network side, the network side will not perform network handover on the UE. In order to realize network switching as soon as possible, and further enable the first service to be successfully initiated, when the RRC layer detects that the adjacent cell meeting the residence condition exists, even if the service quality of the adjacent cell is lower than that of the current service cell, reporting a measurement report as well, and adding a target cell into the measurement report so as to instruct the network side to perform network switching.
Optionally, this step may further comprise the following sub-steps.
1. Generating a second measurement report according to the measurement result in response to the existence of the neighbor cell meeting the handover condition and the existence of the neighbor cell meeting the residence condition, wherein the second measurement report comprises a target cell which is used for indicating permission of cell handover when the measurement result of the neighbor cell is lower than the measurement result of the serving cell and the neighbor cell meets the residence condition;
in one possible implementation, when the RRC layer measures neighbor cells that meet the camping condition but do not meet the handover condition, a second measurement report is generated with a target cell indicating that the neighbor cell measurement is lower than the serving cell but that cell handover is allowed when the camping condition is met.
Illustratively, when the RRC layer measures neighbor cells that meet the camping condition but do not meet the handover condition, a second measurement report is generated, and a cell hotoltendinizer (which may be boolean) is added to the second measurement report, to instruct the network side to allow handover to the neighbor cells.
2. The network side is used for switching the terminal from the serving cell to the adjacent cell when the second measurement report is identified to contain the target cell;
In one possible implementation, when the network receives the measurement report including the target cell, it is known that cell switching needs to be performed for the UE as soon as possible, so as to send a cell switching instruction to the UE, instruct the UE to switch from the serving cell to a neighboring cell meeting the camping condition in the measurement report, so that the UE initiates the first service in the neighboring cell as soon as possible.
3. And switching from the service cell to the neighbor cell according to a cell switching instruction sent by the network side.
In one possible implementation, the RRC layer switches to the neighbor cell according to a cell switching instruction sent by the network side. Even if the service quality of the neighbor cell is not better than that of the service cell, the network switching is still carried out, so that the service can be successfully initiated.
In step 505, in response to the first traffic priority being lower than the second traffic priority, it is determined that the network handover condition is not satisfied and resides in the first network.
In one possible implementation, when the first service priority is lower than the highest service priority in the successfully initiated service, the NAS determines that the first service priority is lower than the second service priority, and at this time, the network handover condition cannot be satisfied, and the NAS needs to reside in the first network.
Illustratively, the first service that is initiated currently is service a, and the second service that is initiated successfully under the 5G network includes service B and service C, where the NAS obtains that the first service priority of service a is level 4, the first service network type is a 4G/5G network, the second service priority of service B is level 5, the second service network type is a 4G/5G network, the second service priority of service C is level 3, and the second service network type is a 4G/5G network. When the service a fails to initiate, the first service priority of the service a is lower than the second service priority of the service B, i.e. the network switching condition is not satisfied, so that the service a needs to reside in the current 5G network.
And step 506, releasing the target service in the second service.
Alternatively, when the initiated target service ends, the target service will be released by the UE.
When the second service priority of the target service is higher than the first service priority, after the target service is released, the first service priority of the first service may be higher than the second service priorities of the remaining second services, so after the target service is released, the NAS needs to further detect whether the first service priority is higher than the second service priorities of the other second services, and further determine whether the network switching condition is satisfied, so as to perform network switching.
In step 507, in response to the first service priority being higher than the second service priority of the other second services, and the first service network type being the target service network type, it is determined that the network switching condition is satisfied, and the first network is switched to the second network, and the other second services are second services other than the target service.
In one possible implementation, the service network type of the currently initiated first service is the target service network type. And after the target service is released, the NAS detects the current first service priority and other second service priorities, and when the first service priority is detected to be higher than the highest second service priority of other second services, the NAS determines that the network switching condition is met, and then the NAS is switched from the first network to the second network.
In combination with the above example, when service B is released, NAS detects that the first service priority of service a is higher than the second service priority of the second service C, and the service network type of service a is a 4G/5G network, so NAS determines that service a satisfies the network switching condition, switches the network from 5G to 4G, and tries to initiate service a under the 4G network.
In response to the first traffic being released, the switch from the second network to the first network is resumed, step 508.
In some possible scenarios, after the first network is switched to the second network, the service quality of the second service that was successfully initiated under the first network may be affected, so in order to further reduce the impact of network switching on the service, the UE will be switched back to the first network by the second network again after the first service is released.
Schematically, as shown in fig. 6, an interaction diagram between the UE side and the network side when the first service is initiated in the case that the first service network type is the target service type and the first service priority is higher than the second service priority is shown.
When the NAS is in a signaling connection state and the UE has a second service which is successfully initiated, the application layer sends a first service initiation request to the NAS, the NAS refuses the first service initiation request due to UAC check, congestion control or network failure, and sends a first service initiation failure response to the application layer, the application layer continues to retry initiating the first service after receiving the response, but the NAS cannot successfully initiate all the time due to UAC check, congestion control or network failure, and when the NAS detects that the number of times of the first service initiation reaches a frequency threshold and the first service priority is higher than the second service priority, the NAS sends a switching request to the RRC layer. The RRC layer performs heterogeneous measurement, searches for a 4G cell suitable for switching, and notifies a network side to perform cell switching after the 4G cell is found, so that the 5G cell is switched into the 4G cell, and further, the second service which is initiated successfully is continued in the 4G cell. And after the switching is successful, the NAS informs the application layer that the UE successfully resides in the 4G cell, and the application layer reinitiates the first service in the 4G cell.
Another illustrative example is shown in fig. 7, which shows a schematic diagram of interaction between the UE side and the network side when the first service is initiated in a case where the first service network type is the target service type and the first service priority is lower than the second service priority.
Similar to the above example, the application layer fails to initiate a service, but the NAS detects that the first service priority is lower than the second service priority, and does not send a handover request to the RRC layer, and needs to stay in the 5G cell continuously, waiting for network recovery. When the second service which is successfully initiated is released, the NAS detects whether the first service priority is higher than the second service priority of other second services, if the first service priority is higher than the second service priority of other second services, a network switching request is sent to the RRC layer, so that the network side is triggered to conduct cell switching, and then the application layer initiates the first service in the 4G cell again after switching to the 4G cell.
In this embodiment, the NAS sets a service priority and a service network type according to a service usage requirement and a service network requirement, and stores the service priority and the service network type, and after the number of times of the first service initiation failure reaches a number threshold, the NAS layer determines whether a network switching condition is satisfied according to the first service priority of the first service, the second service priority of the second service, and the service network type of the first service, and performs network switching when the condition is satisfied. According to the scheme, network switching is performed according to the actual service use requirement of the user and the actual service network requirement, so that the actual requirement of the user can be met, the service can be successfully initiated after the network switching is performed, and the service initiation success rate is improved.
In addition, when the network switching is carried out, when the cell which does not meet the cell switching condition but meets the residence condition is measured, the cell switching is still carried out, so that the service can be initiated as soon as possible without waiting for too long time.
In one possible scenario, the first traffic priority of the first traffic is higher than the second traffic priority of the second traffic, but due to the requirement of the traffic quality of service (Quality of Service, qoS) parameters, the traffic network type of the first traffic indicates that the first traffic is only supported to be initiated under the first network, when the first traffic cannot meet the network handover condition, and needs to reside in the first network. Then, since the QoS parameters of the service may change (e.g. the user actively triggers to change the QoS parameters), and the second network may be able to meet the service requirement after the QoS parameter change, in order to improve the success rate of initiating the first service, in a possible implementation, when the first service network type does not meet the target service network type, the UE determines whether to perform network handover according to the QoS parameter change condition of the first service.
Referring to fig. 8, a flowchart of a service initiation method according to another exemplary embodiment of the present application is shown. The present embodiment is described taking the method performed by the UE as an example, and the process includes the following steps:
In step 802, in response to the first service initiation failure, the number of failures is updated.
For the implementation of steps 801 to 803, reference may be made to steps 501 to 503, which are not repeated in this embodiment.
In step 804, in response to the first service network type not belonging to the target service network type, it is determined that the network handover condition is not satisfied and resides in the first network.
In one possible implementation, when the first service network type does not belong to the target service network type, it is indicated that the first service network type does not support initiation under the second network, and the UE can only camp under the first network and wait for network recovery.
In step 805, in response to the QoS parameter of the first service being changed, the first service support after the QoS parameter change is initiated under the second network system, and the first service priority is higher than the second service priority, switching from the first network to the second network.
In a possible implementation manner, after the QoS parameter of the first service changes, the UE detects whether the second network system can meet the network requirement of the first service, if so, it indicates that the first service can be initiated under the second network system, and if the first service priority is higher than the second service priority, the UE switches from the first network to the second network; if the first service priority is lower than the second service priority, the network recovery still needs to be waited.
Optionally, the QoS parameters include parameters such as a network transmission rate, a network delay, and a transmission reliability, which are not limited in the embodiment of the present application. Illustratively, the first service currently initiated is a game data service, and the network delay requirement is within 8ms, so that the game data service can only be initiated under a 5G network. When the user is urgent to initiate the first service, so that the use requirement is reduced, the network delay requirement index change is triggered, and the time delay requirement index is prolonged to be within 80ms, the game data service can be initiated under the 4G network. At this time, if the service priority of the game data service is higher than the service priority of the successfully initiated service, the UE switches from the 5G network to the 4G network.
For the implementation of this step, reference may be made to step 508, and this embodiment is not described herein.
Schematically, as shown in fig. 9, a schematic diagram of interaction between a UE side and a network side in a case of a service initiation failure when a first service network type does not belong to a target service network type is shown.
The NAS detects a first service network type when the first service network type does not belong to a target service network type (namely, the first network type can only be initiated under a 5G network), the NAS needs to stay in a 5G cell continuously, the 5G network is waited for recovery, if a user reduces the use requirement, and further modifies QoS parameters, so that the NAS detects the first service priority of the first service and the second service priority of the second service when the first service can be initiated under a 4G network, and when the first service priority is higher than the second service priority, the NAS sends a network switching request to the RRC layer, and the network side switches the 5G cell into the 4G cell.
In this embodiment, when the first service cannot be successfully initiated under the second network, the first service may be initiated under the second network by modifying the QoS parameter, so as to perform network switching, so that the first service may be initiated as soon as possible, and the service initiation success rate is improved.
