Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.
As shown in fig. 1, the present functional embodiment provides a wireless communication method applied in a user equipment UE, including:
s110: determining a network quality of a first network;
s120: in response to receiving a redirection instruction for redirecting to a second network when the network quality of the first network meets a preset condition, refusing to execute the redirection instruction, wherein the system bandwidth of the first network is greater than the system bandwidth of the second network;
s130: and according to the redirection indication, keeping connection with the first network.
The wireless communication method provided by the embodiment of the present disclosure is applied to various types of UEs, including but not limited to: the mobile phone, the tablet computer, the wearable device, the vehicle-mounted device or the internet of things UE.
The internet of things UE includes but is not limited to: intelligent household equipment and/or intelligent office equipment.
In some embodiments, a network quality of the first network may be determined, which may be determined by signal strength measurements of cell reference signals.
The first network may be a 5G network but not limited to a 5G network, the second network may be a 4G network but not limited to a 4G network, and the association relationship between the first network and the second network only needs to satisfy that the system bandwidth of the first network is greater than that of the second network.
For example, the network quality metrics include, but are not limited to: reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (QSRQ), Received Signal Strength Indicator (RSSI), and/or Signal-to-Noise Ratio (SNR).
In one embodiment, the network quality is represented by the signal strength alone, and if the network quality of the current first network is good enough, the first network has enough resources and a good enough wireless environment to provide good communication quality, i.e. it is not necessary to switch to the second network. At this time, if the UE receives the redirection instruction sent by the base station, the UE may refuse to execute the redirection instruction. The redirection indication is rejected from being executed, i.e. redirected to the second network.
There are various messages corresponding to the redirection indicator, including but not limited to: RRC release message and/or handover message, etc. The redirection indication carried by the RRC release message and/or the handover message may be a trigger for the UE to redirect to the second network.
The specific content of the redirection indication may at least include: cell information, e.g., cell identity, etc., of the target cell redirected to the second network.
It is worth noting that: the redirection indication in fig. 1 is received before S110, and in fact, the redirection indication may also be received after determining the network quality of the first network.
For example, if the UE receives the redirection instruction, the UE executes the above-mentioned S110, and the reception of the redirection instruction is equivalent to triggering the UE to determine the network quality of the first network.
As another example, the UE may make the determination of the network quality of the first network periodically or based on other triggering events besides the redirection indication. For example, the UE periodically measures the network quality of the first network, and after the network quality measurement of the first network is completed, receives the redirection instruction, and then determines whether the network of the first network meets the preset condition or not and whether execution of the redirection instruction needs to be rejected according to the network quality of the first network measured last time.
In another embodiment, network quality may also be embodied by signal quality. The signal quality relative to the signal strength (i.e. the received power of the cell reference signal, etc.) also takes into account parameters such as the bit error rate, the packet loss rate or the signal-to-noise ratio, etc., to synthetically determine the current network quality of the first network.
The redirection indication may be sent by a network side (e.g., including but not limited to a base station) of the first network based on at least one of:
according to the network measurement result of the UE, determining that the network quality of a first network at the position of the UE is lower than a first threshold and the network quality of a second network is higher than the first threshold; the first threshold may be slightly higher than the strength threshold corresponding to the preset condition that the network quality of the first network reaches;
when the load rate of the first network is higher than the upper limit of the load rate, issuing the data;
according to the load balancing strategy, the load balancing strategy is issued when the load balancing is performed on the second network by the first network;
and when the load rate of the first network is lower than the lower limit of the load rate and the base station of the first network is determined to be closed, the base station is issued.
In some embodiments, the UE rejecting performing the redirection indication comprises: directly ignoring the redirection indication; and/or directly dropping the redirection indication.
In some embodiments, the UE rejecting performing the redirection indication comprises:
if the UE determines to refuse to execute the redirection instruction, carrying out rejection negotiation with a base station of the first network;
and refusing to execute the redirection instruction in response to the refusal negotiation indicating that the UE is allowed to refuse to execute the redirection instruction.
For example, negotiating a rejection with a base station of a first network may include:
reporting the reject reason on the current connection between the UE and the first network; the reject cause may be used to: a base station of a first network determines whether to approve the UE to reject execution of the redirection instruction;
if receiving the negotiation result indicating agreement, the UE refuses to execute the redirection instruction;
and/or the presence of a gas in the gas,
and if the negotiation result indicating rejection is received, the UE executes redirection indication.
The reject reason includes, but is not limited to, at least one of:
a device priority of the UE;
and the service priority of the service to be transmitted by the UE.
The UE can determine whether to approve the UE to reject to execute the redirection instruction or not through the report of the rejection reason, so that unnecessary redirection of the UE is reduced, and the requirement of indicating the UE to execute redirection on a network side can also be considered.
In some cases, the first network may preferentially reject a UE with a low priority and agree that a UE with a high priority rejects the negotiation for execution of the redirection indication, according to the device priority of the UE carried by the rejection reason.
For example, if the first network determines to transfer the load to the second network based on the load balancing policy, the load rate of the first network itself is not very high, and if the UE rejects to execute the redirection instruction, which may result in poor transmission effect of the service data of the UE, the UE may be allowed to reject to execute the redirection instruction. For example, the first network is a network side that does not agree to the UE to reject execution of the redirection instruction because the redirection instruction issued by the base station of the first network needs to be shut down, and the first network determines to shut down, and the UE is disconnected if the UE is not redirected to the second network. For example, if the UE currently has an emergency transmission service and needs to delay redirection or refuse redirection to the second network, the first network may consider agreeing to the UE to refuse redirection; otherwise, the first network may not agree that the UE rejects redirection.
Meanwhile, the UE may remain connected to the first network while or after refusing to perform the redirection instruction, so that network data of the UE may be transmitted through the first network.
The system bandwidth of the first network is larger than that of the second network, so that the transmission rate of the first network is higher than that of the second network, and the UE can reside in the first network with the large system bandwidth for a longer time and with a higher probability through the rejection of the redirection indication redirected to the second network, so that the service transmission rate of the UE is improved, and the transmission quality of service data is ensured.
In some embodiments, S130 may include:
determining a mode of keeping connection with a first network according to a message carrying a redirection instruction;
the connection is maintained in the first network according to the determined manner.
As shown in fig. 2A, the redirection instruction may be carried in the handover message and sent to the UE, so that the UE receives the redirection instruction sent by the base station of the first network by receiving the handover message.
For example, as shown in fig. 2B, S130 may include:
s131: responsive to the redirection indication being carried in the handover message, maintaining a current connection with the first network.
If the redirection instruction is carried in the handover message of the UE to the second network, which is equivalent to that the first network does not directly instruct to disconnect the current connection with the first network, the current connection between the UE and the first network may be continuously used. At this time, the UE may not switch to the cell of the second network involved in the redirection indication. In this case, the UE continues to camp on the first network and communicates using the current connection with the first network by rejecting the handover.
As shown in fig. 3A, the aforementioned redirection indication may also be carried in an RRC Release message (RRC Release).
In one embodiment, as shown in fig. 3B, S130 may include:
s132: reconnecting to the first network in response to the redirection indication being carried in a radio resource control, RRC, release message.
The RRC release message is a message for specially indicating to release the current connection, according to the related technology, the UE can release the current connection when receiving the RRC release message, but because the network quality of the first network meets the preset condition, if the execution of the redirection indication is determined to be refused, the connection is maintained in the first network in a reconnection mode.
In one embodiment, if the redirection indication is RRC connection release, the UE first releases the current connection with the first network in order to maintain the UE staying in the first network, and at the same time, re-establishes a connection with the first network, and the newly established connection may be used for the UE to continue to communicate through the first network. In short, if the network quality of the first network meets the preset condition, the network quality of the current first network can be considered to be better, and the UE can better communicate through the first network.
In one embodiment, the network quality satisfies a predetermined condition, including at least one of:
the signal strength of a cell reference signal of a first network reaches a strength threshold;
the error rate of the data transmitted by the first network is lower than the preset error rate;
and the packet loss rate of the first network transmission data is lower than the preset packet loss rate.
The bit error rate is: the error rate is equal to the ratio of the error code in transmission to the total number of transmitted codes.
The packet loss rate is: refers to the ratio of the number of packets lost in the test to the number of packets sent. The bit error rate may be calculated as follows: the difference between the number of transmitted messages and the data of received messages, and the ratio of the number of transmitted messages.
The manner for determining whether the network quality of the first network meets the preset condition provided in the embodiments of the present disclosure is any one or a combination of the following:
the first method is as follows: the method comprises the steps that a first UE measures a cell reference signal of a first network to obtain the signal intensity of the cell reference signal;
wherein if the measured signal strength is greater than the strength threshold, it is determined that the network quality satisfies a preset condition.
The cell reference signals measured in the embodiments of the present disclosure include, but are not limited to, at least one of:
a channel state information reference signal;
a channel sounding reference signal;
a synchronization signal;
and demodulating the reference signal.
Here, the reference signal of the cell is merely an example, and the specific implementation for determining the network quality of the first network is not limited to the above example.
The strength threshold may be a preset signal strength value, and if the signal strength is greater than the strength threshold, it indicates that the signal quality of the first network of the UE in the location thereof is good enough to support the UE to continue to provide communication services through the first network, that is, the UE may continue to use the large bandwidth of the first network without being redirected to the second network, and enjoy the high data transmission rate and the low transmission delay of the large bandwidth.
In one embodiment, the strength threshold may even be slightly lower than a first threshold at which the first network triggers redirection of the UE to the second network.
The second method comprises the following steps:
the error rate of the data transmitted by the first network is lower than the preset error rate.
In the embodiment of the present disclosure, whether the network quality of the first network is greater than the preset threshold may be measured by using the signal strength of the cell reference signal, and may also be used to determine the bit error rate of the data transmitted by the first network.
For example, the UE may determine whether the network quality of the first network at the current time meets a preset condition according to the error rate of the traffic data transmitted through the first network within a certain time period. For example, if the bit error rate is high, it indicates that the transmission quality of the first network is low, and if the UE continues to stay in the first network, the signal transmission quality of the UE is milky tea. If the bit error rate is low, it indicates that the transmission quality of the first network is relatively high, and the UE continues to camp on the first network, so that high-rate transmission can be performed by means of the large system bandwidth of the first network.
The third method comprises the following steps: the network quality of the first network is measured according to a packet loss rate of data transmitted by the UE and the first network on the current connection, and specifically, if the packet loss rate is determined to be lower than a preset packet loss rate, the network quality of the first network may be considered to meet a preset condition.
The method is as follows:
the combination of two or more than two of whether the signal strength reaches the strength threshold, whether the error rate is lower than the preset error rate and whether the packet loss rate is lower than the preset packet loss rate can be combined.
In other embodiments, determining whether the network quality of the first network satisfies a preset condition may further include: and determining the signal-to-noise ratio of the first network, and if the signal-to-noise ratio reaches the standard, determining that the network quality of the first network meets the preset condition.
In some embodiments, if the UE is a high priority UE, the UE may refuse to be redirected to a second network that is smaller than the system bandwidth of the first network, regardless of its current traffic transmission state.
In other embodiments, if the UE is in the preset area, the UE may also reject the second network redirected to be smaller than the system bandwidth of the first network regardless of its current traffic transmission state. The preset area here is: an area in which the first network provides the communication service is designated.
In some embodiments, reconnecting to the first network in response to the redirection indication being carried in a radio resource control, RRC, release message, comprises:
releasing the current connection with the first network in response to the redirection indication being carried in the RRC release message;
after releasing the current connection with the first network, reconnecting to the first network through a random access procedure.
Since the RRC release message triggers the UE to release the current connection with the first network, in order to maintain the connection with the first network, the UE may request to connect to the first network again through a random access procedure.
For example, the UE requests to connect to the first network again through a 4-step random access procedure; alternatively, the UE requests connection to the first network again through a 2-step random access procedure.
In short, in the random access process, the UE sends a random access request and receives a random access response returned by the first network based on the random access request; and connecting to the first network again according to the random access response, thereby realizing the connection maintenance on the first network.
In some embodiments, in order to allow for implementation of policies such as load balancing on the network side and/or load rate fallback of the first network, in the embodiments of the present disclosure, it is determined whether it is necessary to reject the redirection indication according to a traffic transmission state of the UE. In this way, it is indeed necessary to reject the redirection indication on the UE side to reject the execution of the redirection indication, otherwise the redirection is performed to the second network as much as possible according to the redirection indication on the network side.
Thus, as shown in fig. 4, the method further comprises:
s100: determining a service transmission state of the UE when receiving a redirection instruction;
s120 may include: and refusing to execute the redirection instruction in response to receiving the redirection instruction redirected to the second network when the network quality of the first network meets the preset condition and the service transmission state is the preset state.
A traffic transmission status of the UE is determined, which characterizes traffic data transmission requirements and/or urgency of the UE. If the UE has data being transmitted or has very urgent data being transmitted or waiting to be transmitted, if redirection to the second network may affect data transmission, for example, data transmission is interrupted or data transmission delay is large, it may be considered that it is better not to redirect to the second network first.
For example, the preset state includes at least one of:
the UE is transmitting service data;
predicting that the UE can transmit service data within a preset time;
the UE is started with a preset application.
If the UE is transmitting the service data and is redirected to the second network according to the redirection indication, the service data transmission in the first network is suddenly interrupted, thereby causing the data transmission of the UE to be abnormal.
In an embodiment, if a redirection instruction is received, it is found that the current UE is not transmitting Data, but service Data is expected to be transmitted immediately, and a Data Radio Bearer (DRB) is mapped to a logical channel inside the UE and is immediately about to be transmitted, then if the UE executes the redirection instruction, the UE application layer may consider that Data delay is large or network service response delay is large.
For example, if the service data buffered is larger than the buffer threshold to be sent, it can be predicted that the UE will transmit the service data within a preset time.
For another example, if the UE is encoding the service data to be transmitted, it may be assumed that the UE is predicted to transmit the service data within the preset time.
For another example, if it is predicted that the service data reporting time of the UE will be reached within the preset time according to network-side resource scheduling (e.g., dynamic resource scheduling and/or semi-static resource scheduling), it may be considered that the UE is predicted to transmit the service data within the preset time.
The duration corresponding to the preset time may be: and (3) taking the value of time such as 0.5 to 3 seconds, wherein the specific duration corresponding to the preset time does not depend on the above example.
In another embodiment, if the UE currently starts an application with a high network dependency, the UE may also be considered to have a high data transmission requirement and/or may need to send traffic data at any time.
The default application includes, but is not limited to, at least one of:
an online gaming application;
a live web application;
a web lecture application;
a network voice group chat application;
a network video group chat application;
a multimedia information distribution application. For example, a multimedia information distribution application may include: video upload applications, various video websites or social applications that can post videos, and the like.
Of course, the above is only an example of the preset application, and the specific implementation is not limited to any one of the above.
In one embodiment, the method further comprises:
and if the network quality of the first network does not meet the preset condition and/or the service transmission state of the UE is not the preset state, executing redirection indication.
In one embodiment, the first network is taken as 5G for example, and the second network is taken as 4G for example.
Because the current 5G network does not support VONR call establishment under 5G, the thresholds of RSRP and RSRQ of the current BEAM (which may be considered as a 5G cell) may be set, and if the current measurement result is better than the threshold and the bit error rate is low, the current data service may be maintained, when the network requires release 5G NR and redirects (or lets UE handover) to the LTE network, the UE may reject to the LTE network, and directly rebuild (i.e., a mobility from NR failure flow) on the 5G NR network as follows, so as to continue to perform data service on the 5G NR network, so as to continue to enjoy high-speed and low-delay data service.
