However, since the network performance of the low RAT is usually lower than that of the high RAT, after the UE is redirected from the high RAT to the low RAT, the transmission delay of the data service of the UE is increased, so that the UE cannot obtain continuous high-rate experience, even service interruption occurs, and the data service experience of the user is reduced.
Therefore, how to reduce the influence of the network environment on the data service of the UE becomes an urgent technical problem to be solved.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The network registration method, apparatus and UE provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 shows an architecture diagram of a communication system according to an embodiment of the present application. As shown in fig. 1, the communication system may include a UE 01 and a network device 02.
It should be noted that the devices shown in fig. 1 may be connected wirelessly or through wires. The embodiment of the present application is not specifically limited to this, and may be determined according to actual use requirements.
A UE is a device that provides voice and/or data connectivity to a user, a handheld device with wired/wireless connectivity, or other processing device connected to a wireless modem. A UE may communicate with one or more core network devices via a Radio Access Network (RAN). In the embodiments of the present application, the UE may be a terminal device, such as a mobile phone (or referred to as a "cellular" phone) and a computer with a mobile terminal, or a portable, pocket, hand-held, computer-embedded or vehicle-mounted mobile device, which exchanges languages and/or data with the RAN, for example, a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), and the like. The UE may also be referred to as a user agent (user agent) or the like.
A network device is a device deployed in a RAN for providing wireless communication functionality for a UE. In the embodiment of the present application, the network device may be a base station, and the base station may include various macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different RATs, the names of base station-capable devices may differ. For example, in a 5G system, it may be referred to as a 5G system base station (gNB); in a fourth generation wireless communication (4-generation, 4G) system, such as an LTE system, it may be referred to as an evolved NodeB (eNB); in a third generation (3-generation, 3G) system, it may be referred to as a base station (Node B). As communication technology evolves, the name "base station" may change.
The embodiment of the present application provides a network registration method based on a communication system, such as the communication system shown in fig. 1. As shown in fig. 2, the network registration method includes S201 to S204 described below.
S201, under the condition that a first cell supporting a first RAT is a service cell of the UE, the UE receives a redirection message sent by network equipment.
The redirection message may be used to instruct the UE to switch from the first RAT to the second RAT.
In the embodiment of the present application, the first RAT may be referred to as a high RAT, and the second RAT may be referred to as a low RAT. The version of the first RAT is higher than the version of the second RAT or the performance of the first RAT is better than the performance of the second RAT. For example, the first RAT is 5G, the second RAT is 4G, 3G, or 2G; or the first RAT is 4G, and the second RAT is 3G or 2G; alternatively, the first RAT is 3G and the second RAT is 2G.
In the case that a first cell supporting a first RAT serves the UE, if the network device detects that the UE is transmitting data traffic of a preset type and the signal strength of the first RAT is weak (i.e., the UE is in a weak field environment), the network device may issue a redirection message to the UE to instruct the UE to switch from the first RAT to a second RAT, i.e., fall back from a high RAT to a low RAT.
Alternatively, the preset type of data service may be pre-configured, pre-agreed or configured by the network device. For example, the communication protocol may pre-agree that a low latency data service (e.g., playing a game), a high traffic data service (e.g., playing a video), a persistent data service (e.g., holding an online network conference), etc. are preset types of data services.
Optionally, the redirection message may include frequency point information of the second RAT.
Further, the number of the second RATs may be one or more, and the number of the frequency points corresponding to one second RAT may also be one or more, that is, the redirection message may include at least one frequency point information.
The frequency point information of the second RAT is configured in the redirection message. Therefore, after the UE receives the redirection message, the UE may measure and evaluate the channel quality corresponding to the frequency point information of the second RAT, and report the measurement result to the network device, so that the network device may perform beam indication on the downlink and uplink channels or reference signals, and establish a beam link between the network device and the UE, thereby implementing transmission of the channel or the reference signal.
S202, the UE determines whether the signal quality value of the first cell is greater than or equal to a first threshold value.
In the embodiment of the present application, after the UE receives the redirection message issued by the network device, the UE may first obtain the signal quality value of the first cell, and then determine whether the signal quality value of the first cell is greater than or equal to the first threshold. In case the signal quality value of the first cell is greater than or equal to the first threshold value, the UE may continue to perform S203 described below; in case the signal quality value of the first cell is smaller than the first threshold value, the UE may continue to perform S204 described below.
It should be noted that the first threshold may be used to reflect the ultimate sensitivity of the UE. The ultimate sensitivity depends on the hardware performance of the UE, which corresponds to the ultimate performance of the UE. For UE with good hardware performance, the ultimate sensitivity is higher, and the UE can still normally work in a weak field environment, so that the continuity of data service is ensured; for the UE with poor hardware performance, the ultimate sensitivity is low, and the UE may not work normally in a weak field environment, so that the continuity of the data service cannot be ensured.
Optionally, the ultimate sensitivity of the UE relates to at least one parameter, and thus the first threshold value is determined in dependence on the at least one parameter.
Further, the first threshold value may be determined according to at least one of:
reference Signal Received Power (RSRP);
reference Signal Received Quality (RSRQ);
received Signal Strength Indication (RSSI);
signal-to-noise and interference ratio (SINR);
throughput (throughput) of the serving cell.
It should be noted that the first threshold may also be determined according to any other possible parameters, and may be determined according to actual usage requirements, which is not limited in the embodiment of the present application.
Optionally, the first threshold may be predetermined.
For example, in the UE development and production phase, a test may be performed for a 4G network environment to determine the ultimate sensitivity of the UE. In a 4G network environment, if the UE cannot normally perform data traffic when RSRP is less than-130 dBm and SINR is less than-5 dBm, and the UE can normally perform data traffic when RSRP is greater than or equal to-130 dBm and SINR is greater than or equal to-5 dBm, then RSRP is greater than-130 dBm and SINR is greater than or equal to-5 dBm, which can be used to characterize the ultimate sensitivity of the UE in the 4G network environment. It can be understood that, due to different network performances of different RATs, the ultimate sensitivity of the UE may be different in different RAT network environments. When the RATs used by the first cell are different, the first threshold corresponding to the first area is also different, for example, the first threshold corresponding to 5G is smaller than the first threshold corresponding to 4G.
S203, if the signal quality value of the first cell is greater than or equal to the first threshold, the UE sends a first request message to the network device, where the first request message is used to request the UE to re-register to the first cell.
It should be noted that, after the network device issues the redirection message to the UE, the network device will immediately release the UE. In the case that the network device considers that the UE has been released, although the UE is not registered to other cells except the first cell for a while, in the case that the signal quality value of the first cell is greater than or equal to the first threshold value, it may be determined that the UE can still perform data service normally through the first cell, and therefore the UE needs to send a first request message to the network device to request the UE to re-register to the first cell. Accordingly, the network device receives the first request message and allows the UE to re-register with the first cell so that the first cell can continue to provide network services for the UE.
S204, if the signal quality value of the first cell is smaller than a first threshold value, the UE executes a target processing action according to the signal quality value of at least one pilot frequency adjacent cell supporting the first RAT.
The at least one inter-frequency neighboring cell may be a cell supporting the first RAT and having a frequency different from that of the first area in neighboring cells of the UE.
The target processing action may include any one of:
sending a first request message to the network equipment;
sending a second request message to the network equipment, wherein the second request message is used for requesting the UE to register to a first pilot frequency adjacent cell in at least one pilot frequency adjacent cell;
and sending a third request message to the network equipment, wherein the third request message is used for requesting the UE to register to a second cell, and the second cell is a cell in the cells supporting the second RAT indicated by the redirection message.
Optionally, the signal quality value of the at least one inter-frequency neighboring cell is obtained within a preset time. By setting the preset time, continuous network searching can be avoided, and the power consumption of the UE is reduced.
Optionally, if the signal quality value of the first cell is smaller than the first threshold, the UE may search the at least one inter-frequency neighboring cell according to the frequency point of the at least one inter-frequency neighboring cell in the preset order; then determining the signal quality value of the searched pilot frequency adjacent region; and then executing the target processing action according to the signal quality value of the at least one pilot frequency adjacent cell.
Further, the frequency point of at least one different-frequency neighboring cell is configured by the network device through the system message.
Further, the preset sequence may be determined by the UE according to a measurement result of a signal of a measured pilot frequency neighboring cell, or configured for the network device, or predefined for a protocol, which is not limited in this embodiment of the present application.
Optionally, in this embodiment of the present application, a search condition may be set: the frequency of pilot frequency searching is less than or equal to a preset frequency. Under the condition that the search condition is met, continuous network searching is stopped, and the power consumption of equipment can be reduced.
In order to more clearly illustrate the above-described several target processing actions, S204 may be implemented by any one of the following (1) to (4) as shown in fig. 3 in conjunction with fig. 2.
(1) And if the signal quality value of the first cell is smaller than a first threshold value and larger than or equal to a second threshold value, and the signal quality values of at least one pilot frequency adjacent cell are all smaller than or equal to the signal quality value of the first cell, the UE sends a first request message to the network equipment.
In the embodiment of the present application, the second threshold is smaller than the first threshold. Optionally, the second threshold value may be determined according to at least one of RSRP, RSRQ, RSSI, SINR, throughput.
Optionally, the second threshold is equal to the first threshold — a preset difference; alternatively, the second threshold is equal to the first threshold × a preset ratio, and the preset ratio is smaller than 1. Of course, the second threshold value may also be determined by using other algorithms, and the embodiment of the present application is not limited.
After determining that the signal quality value of the first cell is less than the first threshold value, the UE may further determine whether the signal quality value of the first cell is greater than or equal to a second threshold value. The UE may obtain a signal quality value of at least one inter-frequency neighbor cell supporting the first RAT in a case that the signal quality value of the first cell is greater than or equal to a second threshold value. If the signal quality values of the at least one inter-frequency neighbor cells are all less than or equal to the signal quality value of the first cell, the first cell may provide better service than the at least one inter-frequency neighbor cell, and therefore the UE may send a first request message to the network device to request the UE to re-register with the first cell. Accordingly, the network device receives the first request message and allows the UE to re-register with the first cell.
(2) And if the signal quality value of the first cell is smaller than the first threshold value and larger than or equal to the second threshold value, and the signal quality value of the first pilot frequency adjacent cell is larger than the signal quality value of the first cell, the UE sends a second request message to the network equipment.
After determining that the signal quality value of the first cell is less than the first threshold value, the UE may further determine whether the signal quality value of the first cell is greater than or equal to a second threshold value. The UE may obtain a signal quality value of at least one inter-frequency neighbor cell supporting the first RAT in a case that the signal quality value of the first cell is greater than or equal to a second threshold value. If the signal quality value of a first inter-frequency neighbor of the at least one inter-frequency neighbor is greater than the signal quality value of the first cell, the first inter-frequency neighbor may provide better service than the first cell, and therefore the UE may send a second request message to the network device to request the UE to register with the first inter-frequency neighbor. Correspondingly, the network equipment receives the second request message and allows the UE to register to the first pilot frequency adjacent cell.
(3) And if the signal quality value of the first cell is smaller than the second threshold value and the signal quality value of the first pilot frequency adjacent cell is larger than the signal quality value of the first cell, the UE sends a second request message to the network equipment.
After determining that the signal quality value of the first cell is less than the first threshold value, the UE may further determine whether the signal quality value of the first cell is greater than or equal to a second threshold value. The UE may obtain a signal quality value of at least one inter-frequency neighbor cell supporting the first RAT in a case that the signal quality value of the first cell is less than a second threshold value. If the signal quality value of a first inter-frequency neighbor of the at least one inter-frequency neighbor is greater than the signal quality value of the first cell, the first inter-frequency neighbor may provide better service than the first cell, and therefore the UE may send a second request message to the network device to request the UE to register with the first inter-frequency neighbor. Correspondingly, the network equipment receives the second request message and allows the UE to register to the first pilot frequency adjacent cell.
(4) And if the signal quality value of the first cell is smaller than the second threshold value and the signal quality values of at least one pilot frequency adjacent cell are all smaller than or equal to the signal quality value of the first cell, the UE sends a third request message to the network equipment.
After determining that the signal quality value of the first cell is less than the first threshold value, the UE may further determine whether the signal quality value of the first cell is greater than or equal to a second threshold value. The UE may obtain a signal quality value of at least one inter-frequency neighbor cell supporting the first RAT in a case that the signal quality value of the first cell is less than a second threshold value. If the signal quality value of the at least one pilot frequency neighboring cell is less than or equal to the signal quality value of the first cell, it may be determined that neither the first cell nor the at least one pilot frequency neighboring cell can meet the data service transmission requirement of the UE, and therefore the UE may send a third request message to the network device to request the UE to register to the second cell. Accordingly, the network device receives the first request message and allows the UE to register with the second cell.
The embodiment of the application provides a network registration method, and after a UE receives a redirection message sent by a network device and switched from a first RAT to a second RAT, if the signal quality value of a serving cell of the UE is greater than a threshold value, the UE does not fall back to the second RAT but re-requests the UE to register to the serving cell.
Optionally, with reference to fig. 3, as shown in fig. 4, after the above S201, the network registration method provided in the embodiment of the present application may further include S205 and S206 described below, or include S205 and S207 described below.
S205, the UE determines whether preset conditions are met.
Wherein the preset condition comprises at least one of the following conditions: the UE is in a conversation state, and the times that the UE receives the redirection message in the preset time is more than or equal to the preset times.
S206, under the condition that the preset condition is not met, the UE determines the signal quality value of the first cell.
And S207, under the condition that the preset condition is met, the UE sends a fourth request message to the network equipment, wherein the fourth request message is used for requesting the UE to register to the second cell.
And the second cell is a cell in the cells supporting the second RAT indicated by the redirection message.
For example, the preset conditions include that the UE is in a call state and the number of times that the UE receives the redirection message within the preset time is greater than or equal to the preset number of times. After receiving the redirection message, the UE first determines whether the UE is currently in a call state. And under the condition of the call state, the UE sends a fourth request message for requesting the UE to register to the second cell to the network equipment, namely, the UE falls back to the low RAT. And under the condition that the UE is not in a call state, the UE judges whether the times of receiving the redirection message in the preset time is more than or equal to the preset times. If the times of receiving the redirection message in the preset time is more than or equal to the preset times, the UE sends the fourth request message to the network equipment, so that frequent sending of the redirection message is avoided, namely, the ping-pong effect is avoided; alternatively, if the number of times of receiving the redirection message within the preset time is less than the preset number of times, the UE may determine the signal quality value of the first cell, and then perform S202, S203, S204, and the like in the above embodiments.
Fig. 4 is exemplarily described with reference to fig. 3, and it is understood that fig. 4 may also be combined with fig. 2, and the embodiment of the present application is not limited.
According to the network registration method provided by the embodiment of the application, after the redirection message is received, whether the preset condition is met or not can be judged, and the network registration method directly falls back to the low RAT under the condition that the preset condition is met, so that frequent sending of the redirection message is avoided, and a ping-pong effect is avoided.
