Detailed Description
The present application will be described in further detail with reference to the following drawings and specific embodiments.
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
The technical means described in the embodiments of the present application may be arbitrarily combined without conflict.
In addition, in the examples of the present application, "first", "second", and the like are used for distinguishing similar objects, and are not necessarily used for describing a specific order or a sequential order.
The inter-network roaming refers to that the terminal accesses a network of another operator to use a mobile communication service, where the other operator is different from a home operator corresponding to the terminal (i.e., a communication operator subscribed by a Subscriber Identity Module (SIM) installed in the terminal). In the related art, in a scenario where the heterogeneous network roaming is allowed, the terminal performs network registration in the order of a home 5G network (a 5G network provided by a home operator of the terminal), a roaming 5G network (a 5G network provided by another operator), and a home 4G network (a 4G network provided by a home operator of the terminal), and it can be understood that in this scenario, the terminal preferentially registers the home 5G network. However, when the signal strength of the home 5G network is significantly lower than that of the roaming 5G network, it will cause the terminal residing in the home 5G network to frequently perform network handover due to network unavailability, increasing the power consumption of the terminal.
Based on this, in the embodiment of the present application, when the terminal performs the inter-network roaming, the terminal determines, according to the cell broadcast signal, the signal strength corresponding to the network provided by the home operator of the terminal, determines the signal strength corresponding to the networks provided by other operators, and selects a corresponding network to register according to the determined signal strength, so as to avoid that the terminal still frequently performs network handover during the process of completing network registration and residing, thereby effectively saving the power consumption of the terminal.
The present application will be described in further detail with reference to the following drawings and specific embodiments. In order to better explain the present solution, when the following embodiments are explained, a scenario in which the first network is a 5G network and the second network is a 4G network is taken as an example for explanation.
Fig. 1 shows an implementation flow of a network registration method provided in an embodiment of the present application, where an execution subject of the method may be a terminal, and the method includes:
s101: acquiring cell broadcast signals of at least two first networks; the at least two first networks include a home network and at least one visited network.
The home network is a network provided by an operator to which the terminal belongs, and the visited network is a network provided by other operators except the operator to which the terminal belongs.
In the embodiment of the application, the position of the terminal is covered with at least two 5G networks, and the terminal receives the cell broadcast signal of each 5G network at the position by using an antenna. Among the above at least two 5G networks, there is one home 5G network, and at least one visited 5G network.
In practical applications, the cell broadcast Signal may be a Synchronization Signal/physical broadcast channel block (SS/PBCH block).
S102: and determining the signal strength of each of the at least two first networks according to the acquired cell broadcast signals.
After the terminal receives cell broadcast signals of at least two 5G networks by using the antenna, the terminal analyzes the cell broadcast signals by using the receiver and the demodulation module to determine cell signal parameters corresponding to each 5G network, and the signal intensity of each 5G network can be determined according to the determined cell signal parameters.
In practical application, the location of the terminal may be covered by multiple cells of the same 5G network at the same time, and the terminal may acquire a cell broadcast signal from each cell respectively and determine the signal strength of each cell on the basis. Thus, in an embodiment, when determining the signal strength of each of the at least two first networks, the method comprises:
determining the signal intensity of each cell in at least one cell according to the acquired cell broadcast signal of the first network; the at least one cell is a cell under a corresponding first network;
and selecting the highest signal strength from the determined signal strengths of each of the at least one cell as the signal strength of the corresponding first network.
For example, the terminal acquires cell broadcast signals from two cells under a 5G network provided by a home operator at the same time, and determines that the signal strength of the cell a is-100 dBm, the signal strength of the cell B is-70 dBm, and the signal strength of the cell B is higher, so that the terminal regards the signal strength of the cell B as the signal strength of the 5G network provided by the home operator.
In practical applications, the signal strength of the network may be represented by any of the following types of parameters:
reference Signal Received Power (RSRP);
reference Signal Received Quality (RSRQ), Reference Signal Receiving Quality;
signal to Interference plus Noise Ratio (SINR).
S103: and selecting a network for registration according to the signal strength of each of the at least two first networks.
Here, the terminal determines, according to the acquired cell broadcast signal, the signal strength corresponding to the 5G network provided by the home operator of the terminal, determines the signal strength corresponding to the 5G network provided by another operator, and selects the corresponding 5G network for registration according to the determined signal strength.
In one embodiment, as shown in fig. 2, the selecting a network to register according to the signal strength of each of the at least two first networks includes:
s201: comparing the first signal intensity with the second signal intensity to obtain a comparison result; the first signal strength is the signal strength of a home network; the second signal strength is the signal strength of the visited network with the highest signal strength in the at least one visited network.
Here, the terminal determines the signal strength of the 5G network provided by the home operator and the signal strength of the 5G network provided by the other operator, respectively. In practical applications, when the terminal is located in a position covered with 5G networks provided by at least two other operators at the same time, the value with the highest signal strength in the 5G networks provided by the at least two other operators is determined as the second signal strength.
S202: and under the condition that the comparison result is that the first signal strength is higher, selecting a network according to the first signal strength for registering.
In an embodiment, the selecting a network to register according to the first signal strength includes:
under the condition that the first signal intensity is greater than a first set value, selecting a home network for registration;
and selecting a second network for registration when the first signal strength is less than or equal to the first set value.
Here, when the signal strength of the 5G network is less than or equal to the first set value, it is considered that the signal quality of the 5G network is poor and it is not suitable for the terminal to register and camp on, and therefore, only when the first signal strength is greater than the first set value, the terminal is made to register in the 5G network provided by the home operator, and when the first signal strength is less than or equal to the first set value, the terminal is made to fall back to the 4G network to register and camp on, so as to secure the communication of the terminal.
S203: and under the condition that the comparison result is that the second signal strength is higher, determining a signal strength difference value between the first signal strength and the second signal strength, and selecting a network for registration according to the signal strength difference value.
Under the condition that the second signal strength is higher, firstly, the signal strength difference between the first signal strength and the second signal strength is determined, and then, the network is selected to register according to the signal strength difference.
In an embodiment, the selecting a network to register according to the signal strength difference includes:
and selecting a home network for registration under the condition that the signal intensity difference is smaller than a second set value and the first signal intensity is larger than a first set value.
Under the condition that the signal intensity difference is smaller than the second set value and the first signal intensity is smaller than or equal to the first set value, selecting a network according to the second signal intensity to register;
and under the condition that the signal intensity difference is greater than or equal to the second set value and the second signal intensity is greater than the first set value, selecting the visited network with the highest signal intensity in at least one visited network for registration. And if the signal intensity difference is greater than or equal to the second set value and the second signal intensity is less than or equal to the first set value, the terminal is returned to the 4G network for registration and residence so as to ensure the communication of the terminal.
Here, when the signal strength difference between the 5G network provided by the home operator and the 5G network provided by the other operator is greater than or equal to the second set value, it is considered that the signal quality of the 5G network provided by the other operator is far better than that of the 5G network provided by the home operator, and therefore, if the second signal strength is also greater than the first set value, the 5G network provided by the other operator with the highest signal strength is selected for registration, otherwise, if the second signal strength is less than or equal to the first set value, the terminal is returned to the 4G network for registration and camping, so as to ensure communication of the terminal.
When the difference between the signal strength of the 5G network provided by the home operator and the signal strength of the 5G network provided by the other operator is smaller than the second set value, the difference between the signal quality of the 5G network provided by the other operator and the signal quality of the 5G network provided by the home operator is not much, at this time, if the first signal strength is greater than the first set value, it represents that the signal quality of the 5G network provided by the home operator can meet the communication requirement of the terminal under the 5G network, and the terminal is allowed to register under the 5G network provided by the home operator according to the principle of giving priority to the service provided by the home operator.
When the difference between the signal strengths of the 5G network provided by the home operator and the 5G networks provided by the other operators is smaller than the second set value, if the first signal strength is smaller than or equal to the first set value, the network is further selected for registration according to the second signal strength.
In an embodiment, the selecting a network to register according to the second signal strength includes:
under the condition that the second signal intensity is greater than the first set value, selecting a visited network with the highest signal intensity in at least one visited network for registration;
and selecting a second network for registration when the second signal strength is less than or equal to the first set value.
In addition, for a scenario that the location of the terminal is only covered with the 5G network provided by the home operator, or a scenario that the location of the terminal is only covered with the 5G network provided by another operator, in practical applications, if the signal strength of the covered 5G network is greater than a first set value, the 5G network is selected to register and reside, and if the signal strength of the covered 5G network is less than or equal to the first set value, the terminal is returned to the 4G network to register and reside, so as to ensure communication of the terminal.
In an embodiment, the selecting a network for registration further includes:
and the cell with the highest signal strength in the selected network is used for camping.
As described above, in practical applications, the location of the terminal may be covered by multiple cells of the same 5G network at the same time, and therefore, there is a case where the network selected by the terminal to be registered is covered by multiple cells of the network at the same time, and in this case, the terminal selects a cell with the highest signal strength for camping.
In the embodiment of the application, under the condition that the terminal performs the different-network roaming, the terminal determines the signal intensity corresponding to the network provided by the home operator of the terminal according to the cell broadcast signal, determines the signal intensity corresponding to the networks provided by other operators, and selects the corresponding network for registration according to the determined signal intensity, so that the terminal is prevented from frequently performing network switching in the process of completing network registration and residing, and the power consumption of the terminal is effectively saved.
