Detailed Description
Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless specifically stated otherwise.

The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as exemplary only and not as limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
The inventor of the present disclosure has found that if the 2G &4G single-input dual-standby technology is applied to a 4G &5G network, the following problems may exist: the sending mechanism of the paging message and the overhead message of the 4G network is greatly different from that of the 2G network, and if the terminal monitors the paging message and the overhead message of the 4G network at one time, the time consumption is long, and the loss of the network capacity is large.
The actual situation based on 4G networks is as follows:
paging cycle 1.28s (sec);
MIB message (Master Information Block): a period of 40ms (milliseconds);
SIB1 message (System Information Block 1, first System Information Block): the period is 80 ms;
SIB2 message (System Information Block 2, second System Information Block))/SIB 3 message (System Information Block 3, third System Information Block)) a period of 160 ms.
The terminal returns to the 4G network to update the MIB once, SIB1&2&3 results in a 5G network capacity loss of 0.28/1.28-21.875%. The paging message and the overhead message are not sent at the same time, and if the monitoring is finished once, the time is longer.
For example, the paging message and the system message (e.g., MIB message, SIB1 message, SIB2 message, or SIB3 message) of the 4G network may be transmitted separately. If the paging message is at the beginning of the paging cycle and a system message is at the end of the paging cycle in the paging cycle of a 4G network, the terminal is required to monitor paging in the paging cycle of the entire 4G network. This obviously results in a long time consumption, which in turn results in a long interruption time of the 5G network, and a large loss of 5G network capacity, which seriously affects the user experience.
In view of this, embodiments of the present disclosure provide a method for 5G voice service to implement a single-receiving dual-standby function of a terminal on a 4G network and a 5G network.
Fig. 1 is a flow diagram illustrating a method for 5G voice traffic according to some embodiments of the present disclosure. In the method, the 5G network identifier and the 4G network identifier of the terminal use the same IMSI (International Mobile Subscriber identity Number), and the terminal synchronizes the paging time on the 5G network and the 4G network. As shown in fig. 1, the method may include steps S102 to S104.
In step S102, the 5G network device configures a Gap (time interval) for the terminal to listen to at least one of a 4G network paging message, a MIB message, and a SIB (System Information Block) message, and transmits configuration Information of the Gap to the terminal.
In step S104, the terminal performs paging message processing or system message processing within the Gap.
To this end, methods for 5G voice services according to some embodiments of the present disclosure are provided. In the method, 5G network equipment configures Gap used for monitoring at least one of paging message, MIB message and SIB message by a terminal and sends the configuration information of the Gap to the terminal; and the terminal processes the paging message or the system message in the Gap. The 5G network identification and the 4G network identification of the terminal adopt the same IMSI, and the paging time of the terminal on the 5G network and the paging time of the terminal on the 4G network are synchronized. The method can realize the function of the 5G network voice service falling back to the 4G network, thereby realizing the function of single receiving and double standby of the terminal on the 4G network and the 5G network.
Namely, the method can realize that the 5G terminal with only one receiver can stand by in the 4G network and the 5G network, fall back to the 4G network when voice service occurs, and establish service in the 4G network. In addition, the time for the terminal to monitor the 4G network is short, the time for the terminal to fall back to the 4G network when monitoring the 4G network is reduced, the capacity of the 5G network is ensured, and the complexity of the terminal implementation is reduced (for example, a 5G terminal with only one receiver can be implemented).
In some embodiments, the Gap may include Gap1 (first time interval) for the terminal to listen for 4G network paging messages. Wherein, the 5G network device sends the configuration information of Gap1 to the terminal. The step S104 may include: the terminal measures and listens for 4G network paging messages within the Gap 1.
Fig. 2A is a schematic diagram illustrating Gap1 according to some embodiments of the present disclosure.
In some embodiments, the configuration information of the Gap1 may include a start time of the Gap1, a first duration (or referred to as a first duration), and a first period.
As shown in fig. 2A, the starting time of the Gap1 is the Paging time (PO) of the 4G network Paging message, i.e., the time length required for measuring the signal strength (measurement time length). For example, if the paging time of the 4G network paging message is 10 th millisecond, and the time duration required for measuring the signal strength is 4 milliseconds, the starting time of the Gap1 is 6 th millisecond.
As shown in fig. 2A, the first duration is the duration of receiving the 4G network paging message + the duration of measuring the signal strength.
In some embodiments, the first period may be a DRX (Discontinuous Reception) period of the terminal on the 4G network.
PO can be calculated using known methods. For example, the calculation method of PO is as follows:
i_s＝floor(UE_ID/N)mod Ns
-T:DRX cycle of the UE.
-nB:4T,2T,T,T/2,T/4,T/8,T/16,T/32.
-N:min(T,nB)
-Ns:max(1,nB/T)
-UE_ID:IMSI mod 1024.

in some embodiments, the Gap may include Gap2 (second time interval) for the terminal to listen for MIB messages. Wherein, the 5G network device sends the configuration information of Gap2 to the terminal. The step S104 may include: the terminal measures and updates MIB messages within the Gap 2.
Fig. 2B is a schematic diagram illustrating Gap2 according to some embodiments of the present disclosure.
In some embodiments, the configuration information of the Gap2 may include a start time, a second duration (or referred to as a second duration), and a second period of the Gap 2.
As shown in fig. 2B, the starting time of the Gap2 is the time corresponding to the starting subframe of the MIB message, which is the time duration required for measuring the signal strength.
As shown in fig. 2B, the second duration is the duration corresponding to the number of subframes required for transmitting the MIB message + the duration required for measuring the signal strength.
In some embodiments, the second period may be a predetermined period. For example, the second period may be 40 ms.
In some embodiments, the SIB message may include a SIB1 (first system information block) message. The Gap may include a Gap3 (third time interval) for the terminal to listen to the SIB1 message. Wherein, the 5G network device sends the configuration information of Gap3 to the terminal. The step S104 may include: the terminal measures and updates the SIB1 message within the Gap 3.
Fig. 2C is a schematic diagram illustrating Gap3, according to some embodiments of the present disclosure.
In some embodiments, the configuration information of the Gap3 may include a start time, a third duration (or referred to as a third duration), and a third period of the Gap 3.
As shown in fig. 2C, the starting time of the Gap3 is the time corresponding to the starting subframe of the SIB1 message, which is the time length required for measuring the signal strength.
As shown in fig. 2C, the third duration is the duration corresponding to the number of subframes required to transmit the SIB1 message + the duration required to measure the signal strength.
The third period may be configurable. In some embodiments, this third period ≧ the transmission period of the SIB1 message.
In some embodiments, the SIB message may include a SIB2 (second system information block) message. The Gap may include a Gap4 (fourth time interval) for the terminal to listen to the SIB2 message. Wherein, the 5G network device sends the configuration information of Gap4 to the terminal. The step S104 may include: the terminal measures and updates the SIB2 message within the Gap 4.
Fig. 2D is a schematic diagram illustrating Gap4 according to some embodiments of the present disclosure.
In some embodiments, the configuration information of the Gap4 may include a start time of the Gap4, a fourth duration (alternatively referred to as a fourth duration), and a fourth period.
As shown in fig. 2D, the starting time of the Gap4 is the time corresponding to the starting subframe of the SIB2 message, which is the time period required for measuring the signal strength.
As shown in fig. 2D, the fourth duration is the duration corresponding to the number of subframes required to send the SIB2 message + the duration required to measure the signal strength.
The fourth period may be configurable. In some embodiments, this fourth period ≧ the transmission period of the SIB2 message.
It should be noted that, in addition to the Gap1 to Gap4, the 5G network device according to some embodiments of the present disclosure may further set another Gap, so that the device may be used to listen to other system messages of the terminal. For example, Gap5 (fifth time interval) may be configured, and this Gap5 may be used for the terminal to listen to SIB3 (third system information block) messages, and thus the scope of the present disclosure is not limited thereto.
Fig. 3 is a flow chart illustrating methods for 5G voice services according to further embodiments of the present disclosure. As shown in fig. 3, the method may include steps S302 to S310.
In step S302, the 5G network device configures a Gap for the terminal to listen to at least one of the 4G network paging message, the MIB message, and the SIB message, and transmits configuration information of the Gap to the terminal.
In step S304, the terminal performs paging message processing or system message processing within the Gap. The 5G network identification and the 4G network identification of the terminal adopt the same IMSI. The terminal synchronizes paging times on the 5G network and the 4G network.
In step S306, the 5G network device determines whether the paging time of the 5G network paging message is within the Gap. If so, the process proceeds to step S308; otherwise the process proceeds to step S310.
In step S308, if the paging time of the 5G network paging message is within the Gap, the paging time is corrected so that the paging time of the 5G network paging message is outside the Gap.
In some embodiments, the step of correcting the paging occasion may comprise: calculating the time offset (Delta) which enables the paging time of the 5G network paging message to be positioned outside the Gap; and correcting the paging time by using the time offset.
For example, the paging time of the current 5G network paging message is located at the 5 th millisecond, and the starting time of the current Gap1 is located at the 4 th millisecond, so that the paging time of the current 5G network paging message is outside the Gap1, the time offset may be calculated to be 2 milliseconds. Then, the paging time is corrected by using the time offset, and the corrected paging time is located at the 3 rd millisecond, so that the paging time of the current 5G network paging message is outside the Gap 1.
In some embodiments, after calculating the time offset, the 5G network device may further send the time offset to the corresponding terminal through a dedicated signaling. In this way, the terminal also obtains the time offset so that it can keep consistent with the transmission time of the 5G network paging message when listening to the 5G network paging message.
In step S310, if the paging time of the 5G network paging message is not within the Gap, the paging time is not corrected.
In the present disclosure, the range within the Gap includes the boundary point of the Gap (i.e., the time at the Gap boundary), and the range outside the Gap does not include the boundary point of the Gap.
To this end, methods for 5G voice services according to further embodiments of the present disclosure are provided. In the method, after configuring Gap, 5G network equipment judges whether the paging time of the 5G network paging message is in the Gap, if the paging time is in the Gap, the paging time is corrected, so that the paging time of the 5G network paging message is out of the Gap; if the paging time is outside the Gap, the paging time is not corrected. The method not only realizes the function of the 5G network voice service falling back to the 4G network, but also reduces the time for falling back to the 4G network when the terminal monitors the 4G network, and ensures the capacity of the 5G network. In addition, the method can solve the problem of avoiding the conflict between the paging message sending time of the 4G network and the paging message sending time of the 5G network.
Fig. 4 is a flow chart illustrating methods for 5G voice services according to further embodiments of the present disclosure. As shown in fig. 4, the method may include steps S401 to S410.
In step S401, the 5G network identifier and the 4G network identifier of the terminal are set to be the same IMSI.
In step S402, the paging time synchronization of the terminal on the 5G network and the 4G network is set.
The two steps are beneficial to accurately calculating the paging time of the 4G network in the subsequent steps.
