Description
Technical Field
The application belongs to the technical field of communication, and particularly relates to a network registration method and device.
Background
In a case where a UE (user equipment) is in a network environment with poor communication quality, in order to prevent the UE from dropping the network, the network device typically redirects the UE from a high RAT (radio access technology ) to a low RAT, for example: a handover is made from a fifth generation wireless communication (5-generation, 5G) system to a long term evolution (long term evolution, LTE) system.
However, since the network performance of the low RAT is generally lower than that of the high RAT, the transmission delay of the data service of the UE will be increased after the UE is redirected from the high RAT to the low RAT, so that the UE cannot obtain continuous high-rate experience, and even service interruption occurs, thereby reducing the data service experience of the user.
Therefore, how to reduce the influence of the network environment on the data traffic of the UE is a technical problem to be solved.

Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described 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.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The network registration method, the device and the UE provided by the embodiment of the application are described in detail below through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
Fig. 1 shows a schematic 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.
The devices shown in fig. 1 may be connected wirelessly or by wires. The embodiment of the application is not particularly limited in any way, and can 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 connection capabilities, or other processing device connected to a wireless modem. The UE may communicate with one or more core network devices via a radio access network (radio access network, RAN). In an embodiment of the present application, the UE may be a terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, or may be a portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile device that exchanges voice and/or data with the RAN, such as a personal communication service (personal communication service, PCS) phone, cordless phone, session Initiation Protocol (SIP) phone, wireless local loop (wireless local loop, WLL) station, personal digital assistant (personal digital assistant, PDA) or the like. The UE may also be referred to as a user agent (UE agent) or the like.
A network device is a device deployed in a RAN for providing wireless communication functionality for UEs. In the embodiment of the application, the network device may be a base station, and the base station may include macro base stations, micro base stations, relay stations, access points, and the like in various forms. In systems employing different RATs, the names of base station capable devices may vary. 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 mobile communication (3G) system, it may be called a base station (Node B). As communication technology evolves, the name "base station" may change.
Based on a communication system, for example, a communication system as shown in fig. 1, an embodiment of the present application provides a network registration method. As shown in fig. 2, the network registration method includes S201 to S204 described below.
S201, in a case that a first cell supporting the first RAT is a serving cell of the UE, the UE receives a redirection message sent by the network device.
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 release of the first RAT is higher than the release 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, and the second RAT is 4G, 3G, or 2G; alternatively, 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 where the UE is served by a first cell supporting a first RAT, if the network device detects that the UE is transmitting a preset type of data traffic and the signal strength of the first RAT is weak (i.e., the UE is in a low-field environment), the network device may issue a redirect message to the UE to instruct the UE to switch from the first RAT to the second RAT, i.e., fall back from the high RAT to the low RAT.
Alternatively, the above-mentioned preset type of data traffic may be preconfigured, pre-agreed, or network device configured. For example, the communication protocol may pre-agree on a low latency data service (e.g., playing a game), a high volume data service (e.g., playing a video), a persistent data service (e.g., holding an online network conference), etc. to be a pre-set type of data service.
Optionally, the redirection message may include frequency point information of the second RAT.
Further, the number of the second RATs is 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.
Since 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 be used for establishing a beam link between the network device and the UE, so as to implement transmission of the channels or reference signals.
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 application, after the UE receives the redirection message issued by the network device, the UE may first acquire 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 value. In case that 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 that 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 value 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 the UE with good hardware performance, the ultimate sensitivity is higher, and the UE can still work normally in a low-field environment, so that the continuity of data service is ensured; for the UE with poor hardware performance, the ultimate sensitivity is lower, and the UE can not work normally in a low-field environment, so that the continuity of data service can not be ensured.
Optionally, the ultimate sensitivity of the UE relates to at least one parameter, and the first threshold value is thus determined in dependence of the at least one parameter.
Further, the first threshold value may be determined based on at least one of:
reference signal received power (reference signal received power, RSRP);
reference signal received quality (reference signal received quality, RSRQ);
a received signal strength indication (received signal strength indication, RSSI);
signal-to-interference-plus-noise ratio (SINR);
throughput (throughput) of the serving cell.
It should be noted that, the first threshold may be determined according to any other possible parameter, and may be determined according to actual use requirements, which is not limited by the embodiment of the present application.
Alternatively, the first threshold value may be preset.
Illustratively, during the UE development and production phase, tests 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 service when RSRP is < -130dBm and SINR is < -5dBm, and the UE can normally perform data service when RSRP is more than or equal to-130 dBm and SINR is more than or equal to-5 dBm, RSRP= -130dBm and SINR= -5dBm can be used for representing the ultimate sensitivity of the UE in the 4G network environment. It will be appreciated that the ultimate sensitivity of the UE may be different in different RAT network environments due to different network performance of different RATs. In the case that the RATs adopted by the first cells are different, the first threshold value corresponding to the first area is also different, for example, the first threshold value corresponding to 5G is smaller than the first threshold value corresponding to 4G.
And S203, if the signal quality value of the first cell is greater than or equal to a first threshold value, the UE sends a first request message to the network equipment, wherein the first request message is used for requesting 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 immediately releases 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 than the first cell temporarily, it may be determined that the UE can still perform the data service normally through the first cell in the case that the signal quality value of the first cell is greater than or equal to the first threshold value, so 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 may continue to provide network services for the UE.
S204, if the signal quality value of the first cell is smaller than the first threshold value, the UE executes the target processing action according to the signal quality value of at least one different frequency neighbor cell supporting the first RAT.
The at least one inter-frequency neighbor cell may be a cell supporting the first RAT and having a frequency different from that of the first region among neighbor cells of the UE.
The target processing actions described above may include any of the following:
sending a first request message to a network device;
sending a second request message to the network device, wherein the second request message is used for requesting the UE to register to a first different frequency neighbor cell in the at least one different frequency neighbor 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 used for redirecting the cell which supports the second RAT and is indicated by the message.
Optionally, the signal quality value of the at least one different frequency neighboring cell is acquired in a preset time. By setting the preset time, continuous network searching can be avoided, so that 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 for at least one different frequency neighboring cell according to a preset sequence according to the frequency point of the at least one different frequency neighboring cell; determining the signal quality value of the searched inter-frequency neighbor cell; and then executing target processing action according to the signal quality value of the at least one inter-frequency neighbor cell.
Further, the frequency point of at least one different frequency neighbor 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 the measured inter-frequency neighbor cell, or configured by the network device, or predefined by a protocol, which is not limited by the embodiment of the present application.
Optionally, the embodiment of the application may set a search condition: the number of different frequency searches is less than or equal to a preset number. Under the condition that the search condition is met, the continuous network search is stopped, and the power consumption of the equipment can be reduced.
In order to more clearly illustrate the above-described several target processing actions, as shown in fig. 3 in conjunction with fig. 2, S204 may be implemented by any one of the following (1) to (4).
(1) 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 at least one inter-frequency neighbor cell is 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 application, the second threshold value is smaller than the first threshold value. Optionally, the second threshold value may be determined according to at least one of RSRP, RSRQ, RSSI, SINR, throughput.
Optionally, the second threshold value=the first threshold value-the preset difference value; or, the second threshold value=the first threshold value×a preset ratio, the preset ratio being smaller than 1. Of course, the second threshold value may also be determined by using other algorithms, which are not limited by the embodiment of the present application.
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 the second threshold value. The UE may acquire a signal quality value of at least one inter-frequency neighbor supporting the first RAT in case 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 cell are each less than or equal to the signal quality value of the first cell, the first cell may provide a better service than the at least one inter-frequency neighbor cell, and thus 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) 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 inter-frequency neighbor 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 the second threshold value. The UE may acquire a signal quality value of at least one inter-frequency neighbor supporting the first RAT in case 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 a better service than the first cell, and thus 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 device receives the second request message and allows the UE to register with the first inter-frequency neighbor cell.
(3) If the signal quality value of the first cell is smaller than the second threshold value and the signal quality value of the first inter-frequency neighbor 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 the second threshold value. In case that the signal quality value of the first cell is smaller than the second threshold value, the UE may acquire the signal quality value of at least one inter-frequency neighbor supporting the first RAT. 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 a better service than the first cell, and thus 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 device receives the second request message and allows the UE to register with the first inter-frequency neighbor cell.
(4) If the signal quality value of the first cell is smaller than the second threshold value and the signal quality value of at least one inter-frequency neighbor cell is 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 the second threshold value. In case that the signal quality value of the first cell is smaller than the second threshold value, the UE may acquire the signal quality value of at least one inter-frequency neighbor supporting the first RAT. If the signal quality value of at least one inter-frequency neighbor cell is less than or equal to the signal quality value of the first cell, then it may be considered that both the first cell and the at least one inter-frequency neighbor cell cannot meet the data traffic 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 with 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, 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 larger than a threshold value, the UE does not fall back to the second RAT, but requests the UE to register to the serving cell again, so that compared with the fall back to the second RAT, the method ensures the continuity of data service, reduces the influence of a network environment on the data service of the UE, and further improves the data service experience of a user.
Optionally, as shown in fig. 4 in conjunction with fig. 3, after S201, the network registration method provided in the embodiment of the present application may further include S205 and S206 described below, or S205 and S207 described below.
S205, the UE determines whether a preset condition is met.
Wherein the preset conditions include at least one of the following: the UE is in a call state, and the number of times that the UE receives the redirection message in the preset time is greater than or equal to the preset number of 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.
Wherein the second cell is a cell of the cells supporting the second RAT indicated by the redirection message.
For example, taking a preset condition including that the UE is in a call state and the number of times the UE receives the redirection message within a preset time is greater than or equal to a preset number of times as an example. After receiving the redirection message, the UE first determines whether it is currently in a talk state. In the case of a talk state, the UE sends a fourth request message to the network device requesting the UE to register with the second cell, i.e. performs fallback to the low RAT. And under the condition of not being in a call state, the UE judges whether the number of times of receiving the redirection message within the preset time is larger than or equal to the preset number of times. If the number of times of receiving the redirection message within the preset time is greater than or equal to the preset number of times, the UE transmits the fourth request message to the network equipment, so that frequent transmission of the redirection message is avoided, namely, the ping-pong effect is avoided; alternatively, if the number of times the redirection message is received within the preset time is less than the preset number of times, the UE may determine the signal quality value of the first cell first and then perform S202, S203, S204, etc. in the above-described embodiments.
It should be noted that, fig. 4 is taken as an example in conjunction with fig. 3, and it is to be understood that fig. 4 may also be combined with fig. 2, and the embodiment of the present application is not limited thereto.
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 can be judged first, and the network registration method falls back to the low RAT directly under the condition that the preset condition is met, so that the redirection message is prevented from being sent frequently, namely, the ping-pong effect is avoided.
It should be noted that, in the network registration method provided in the embodiment of the present application, the execution body may be a network registration device, or a control module in the network registration device for executing the network registration method. In the embodiment of the present application, a network registration device executes a network registration method as an example, and the network registration device provided in the embodiment of the present application is described.
