Detailed Description
Before describing the technical solution of the embodiment of the present invention in detail, a description will be given of a related art.
In the related art, after the terminal is synchronized with the network device, the terminal can perform services such as voice call and data transmission with the network device. In actual application, the terminal can realize synchronization with the network equipment through cell registration. In the process of synchronizing the terminal and the network device, if the time for synchronizing the terminal and the network is too long, the terminal cannot normally perform voice communication, data transmission and other services with the network device, thereby seriously affecting the user experience.
Based on this, in various embodiments of the present invention, an nth cell registration request is sent to a network device, and a first timer is controlled to start counting; in the process of initiating the Nth cell registration, when the counting time length of the first timer is less than or equal to the set time length T, if a registration failure message sent by the network equipment is received, at least one of the set time length T and the registration time threshold of the first timer is adjusted, and a (N + 1) th cell registration request is continuously sent to the network equipment; wherein, N is 1, …, M-1; m is an integer greater than 1.
It should be noted that, in the embodiment of the present invention, in order to shorten the time for synchronizing the terminal and the network device, after a cell registration failure is attempted, the set time length T and/or the registration number threshold of the first timer is adjusted to improve the success rate of cell registration performed by the terminal, so as to achieve the purpose of shortening the time for synchronizing the terminal and the network device.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The embodiment of the invention provides a cell registration method, which is applied to terminal equipment, and fig. 1 is a schematic flow chart for implementing the cell registration method in the embodiment of the invention; as shown in fig. 1, the method includes:
step 101: and sending an Nth cell registration request to the network equipment, and controlling a first timer to start counting.
Step 102: in the process of initiating the Nth cell registration, when the counting time length of the first timer is less than or equal to the set time length T, if a registration failure message sent by the network equipment is received, at least one of the set time length T and the registration time threshold of the first timer is adjusted.
Step 103: and continuously sending the (N + 1) th cell registration request to the network equipment.
Wherein, N is 1, …, M-1; m is an integer greater than 1.
Here, in step 101, in practical application, the terminal may perform cell registration multiple times in some scenarios, such as an EPSFB scenario, to establish synchronization with the network device. The interval between the initiation of the adjacent two cell registrations by the terminal may be determined by the first timer. The EPSFB refers to a core network fallback technique, that is, a voice over 5G solution, for example, voice fallback to 4G is supported by VoLTE to establish a voice call.
Here, in step 102, in actual application, after initiating cell registration, the terminal stops cell registration if receiving a registration success message sent by the network device within the set duration of the first timer, but after receiving a registration failure message sent by the network device within the set duration of the first timer, initiates a cell registration request again. Considering that the time synchronization between the terminal and the network device is too long due to the fixed cell registration interval in the related art, and the terminal cannot perform normal voice call and data transmission service, the interval of subsequent cell registration can be adjusted, and/or the threshold of the registration times can be adjusted, so as to shorten the time for synchronizing the terminal and the network device.
Here, in step 103, in actual application, if the set time length T of the first timer is adjusted, after the terminal sends a cell registration request for the (N + 1) th time to the network device, the set time length of the first timer is changed to the adjusted time length; if the registration time threshold is adjusted, after the terminal sends the (N + 1) th cell registration request to the network device, the set duration of the first timer may be T or may be an adjusted duration.
The following is a detailed description of how to implement a procedure for shortening the time period for synchronization of the terminal with the network.
In the first situation, before the cell registration frequency of the terminal does not reach the registration frequency threshold, if a registration failure message sent by the network device is received, the set time length T of the first timer is adjusted to shorten the synchronization time length of the terminal and the network.
Specifically, the time interval between two adjacent cell registrations may be determined by using the initial setting time length T of the first timer and the threshold of the registration times.
In practical application, when the registration time threshold is not adjusted, in order to decrease the time interval of each cell registration as the cell registration time increases, the set time of the first timer may be adjusted by using the registration time threshold and the initial set time of the first timer.
Based on this, in an embodiment, adjusting the set duration T of the first timer includes:
the set time period T of the first timer is adjusted to T-N x (T/M).
Here, the set time period T of the first timer may refer to an initial set time period T.
For example, as shown in table 1, taking the first timer as the timer T3511 as an example, assuming that the initial setting time length T of the timer T3511 is 10s, and the total number M of cell registrations is 5 times, when the terminal initiates a 1 st cell registration request to the network device, the timer T3511 starts counting, and when the counting time length of the timer T3511 is equal to 10s, if a registration failure message sent by the network device is received, the initial setting time length of the timer T3511 is adjusted to 10-1 × (10/5) ═ 10-2 ═ 8 s; in analogy, after the terminal initiates a cell registration request for the 2 nd time to the network device, the timer T3511 starts counting, and when the counting duration of the timer T3511 is equal to 8s or less, if a registration failure message sent by the network device is received, the initial setting duration of the timer T3511 is adjusted to 10-2 × (10/5) ═ 10-4 ═ 6 s; when a terminal initiates a 3 rd cell registration request to a network device, a timer T3511 starts counting, and when the counting time duration of the timer T3511 is equal to 6s or less, if a registration failure message sent by the network device is received, the initial set time duration of the timer T3511 is adjusted to 10-3 x (10/5) which is 10-6 which is 4 s; when a terminal initiates a 4 th cell registration request to a network device, a timer T3511 starts counting, and when the counting time of the timer T3511 is equal to or less than 4s, if a registration failure message sent by the network device is received, the initial set time of the timer T3511 is adjusted to 10-4 x (10/5) which is 10-8 which is 2 s; when the terminal initiates a cell registration request for the 5 th time to the network device, the timer T3511 starts counting, and when the counting duration of the timer T3511 is equal to or less than 2s, if a registration failure message sent by the network device is received, the terminal stops initiating the registration request to the network device.
| Nth cell registration | Set time length T of timer T3511 |
| N＝1 | T＝10s |
| N＝2 | T＝T-N×(T/M)＝10-1×(10/5)＝8s |
| N＝3 | T＝T-N×(T/M)＝10-2×(10/5)＝6s |
| N＝4 | T＝T-N×(T/M)＝10-3×(10/5)＝4s |
| N＝5 | T＝T-N×(T/M)＝10-4×(10/5)＝2s |
TABLE 1
In the second case, when the cell registration frequency of the terminal reaches the registration frequency threshold, if a registration failure message sent by the network equipment is received, the cell registration to the network equipment is stopped, and a cell registration request is initiated to the network equipment again after the cell registration is stopped for a certain time period.
Specifically, the fixed duration of the first timer may be determined according to a time interval of cell registration performed before the registration number threshold.
In practical application, before the terminal performs cell registration and does not reach the registration frequency threshold, the time interval of each cell registration can be reduced along with the increase of the cell registration frequency, and after the terminal performs cell registration and reaches the registration frequency threshold, the time interval of each cell registration can be a fixed value, namely the time interval of the previous cell registration before the registration frequency threshold.
Based on this, in an embodiment, the method further comprises:
the method further comprises the following steps:
sending a cell registration request for the Mth time to the network equipment, stopping sending the registration request to the network equipment if receiving a registration failure message sent by the network equipment, and controlling a first timer to start counting;
when the counting duration of the first timer is equal to the preset duration, sending an M + M-th cell registration request to the network equipment;
in the process of initiating the M + M times of cell registration, if a registration failure message sent by the network equipment is received, adjusting the set time length T of the first timer to a fixed value, and continuously sending a M + M +1 times of cell registration request to the network equipment;
wherein m is a positive integer.
Here, the adjusting the set time length T of the first timer to a fixed value includes:
the set time period T of the first timer is adjusted to T- (M-1) × (T/M).
For example, as shown in table 2, taking the first timer as the timer T3511 as an example, assuming that the initial setting time length T of the timer T3511 is 10s, and the registration time threshold M is 5 times, when the cell registration time is equal to the registration time threshold 5, if a registration failure message sent by the network device is received, the initiation of the registration request to the network device is stopped, and the timer T3511 is controlled to start counting; when the counting time length of the timer T3511 is equal to the preset time length, a 6 th cell registration request is sent to the network device, in the process of initiating the 6 th cell registration, if a registration failure message sent by the network device is received, the set time length T of the timer T3511 is adjusted to a fixed value T- (M-1) × (T/M) ═ 10- (5-1) × (10/5) ═ 2s, and the 7 th cell registration request is continuously sent to the network device.
| Nth cell registration | Set time length T of timer T3511 |
| N＝5 | T＝T-N×(T/M)＝10-4×(10/5)＝2s |
| N＝6 | T＝T-N×(T/M)＝10-4×(10/5)＝2s |
| N＝7 | T＝T-N×(T/M)＝10-4×(10/5)＝2s |
| N＝8 | T＝T-N×(T/M)＝10-4×(10/5)＝2s |
| N＝9 | T＝T-N×(T/M)＝10-4×(10/5)＝2s |
TABLE 2
In practical application, the terminal can perform cell registration for multiple times in some scenarios, such as an EPSFB scenario, so as to establish synchronization with the network device. The interval time between two adjacent cell registrations initiated by the terminal may be determined by a first timer, so that when it is detected that the terminal is in a specific scene, the initial set duration of the first timer may be set to T.
Based on this, in an embodiment, the method further comprises:
detecting whether a current scene meets a preset condition or not;
and when the current scene is detected to meet the preset condition, setting the set duration of the first timer to be T.
Here, it is determined that the current scene satisfies the preset condition when one of the following operations is detected:
the terminal successfully executes the cell registration;
the method comprises the steps of starting up and shutting down operation aiming at a terminal;
the terminal starts or closes a flight mode;
and performing hot plug operation aiming at the terminal.
Here, after the terminal may initiate a cell registration request in one of the scenarios of terminal power on/off, switch flight mode, hot plug, EPSFB call, etc., if the network device does not process the message but directly issues RRC Release, the cell registration may be failed this time, and therefore, the terminal may attempt to perform cell registration for multiple times. In order to prevent the terminal from attempting to perform cell registration for multiple times in one of the scenarios of terminal power on/off, switch flight mode, hot plug, EPSFB call, etc., the initial setting duration of the first timer may be set.
For example, taking a 5G network as an example, for one of the scenarios of terminal power on/off, switch flight mode, hot plug, EPSFB call, etc., the terminal will initiate 5G cell registration, and the flow of successful 5G cell registration is shown in table 3. However, in practical application, after the terminal initiates the 5G cell registration request, if the network device does not process the message but directly issues RRC Release, the cell registration will fail, and therefore, the terminal will attempt to perform cell registration for multiple times, and thus, when it is detected that the current scene meets the preset condition, the set duration of the first timer may be set to T. It should be noted that, in the process of adjusting the set time length T of the first timer, if it is detected that the current scene meets the preset condition, the set time length of the first timer may also be reset to T.

TABLE 3
In an example, as shown in fig. 2, taking a first timer as the timer T3511 as an example, a process of adjusting the set duration T of the timer T3511 is described, which includes:
step 201: and when detecting that the current scene meets the preset condition, the terminal initializes the set duration of the timer T3511 to T.
Here, the current scenario is an EPSFB scenario, i.e. voice fallback to 4G, supported by VoLTE to establish a voice call.
Here, the set time period T of the timer T3511 is initialized to 10 s.
Step 202: the terminal sends a cell registration request for the Nth time to the network equipment and controls a timer T3511 to start counting; when the counting time of the timer T3511 is less than or equal to the set time T, if the registration failure message sent by the network device is not received, execute step 203; otherwise, step 204 is performed.
Wherein, N is 1, …, M-1; m is an integer greater than 1.
Here, in the EPSFB scenario, after establishing the VoLTE voice call, the terminal needs to initiate a registration request to the 5G cell again.
Step 203: the terminal stops sending the cell registration request to the network device.
Step 204: the terminal adjusts the set time length T of the timer T3511 and continues to send the (N + 1) th cell registration request to the network device.
Here, fig. 3 is a process of adjusting the set time period T of the timer T3511 at N < M, including:
step 301: the terminal determines the registration times N and the registration time threshold M of the current cell;
here, M is equal to 5.
Step 302: the terminal adjusts the set time period T of the timer T3511 to T-N x (T/M).
Here, the terminal initiates a cell registration request for the nth (N <5) time, and upon receiving an RRC Release message from the network device, shortens the set duration T of the timer T3511 to 10-N × (10/5) to 10-N × 2.
Here, adjusting the set time length T of the timer T3511 has the following advantages:
(1) after the terminal initiates a cell registration request, if the network device does not process the message, the network device directly issues registration failure messages such as RRC Release and the like, and in order to avoid the problem that the terminal and the network are out of step due to the registration failure, the set duration of the timer T3511 is adjusted, so that the terminal can be ensured to quickly recover normal voice call and data service, and the use experience of the user is ensured.
(2) A method for non-standard timer T3511 is proposed, when the registration times of the cell does not reach the total times of the cell, the set time length of the timer T3511 is shortened along with the increase of the trial times, thereby shortening the time for synchronizing the network and the terminal.
(3) Under an EPSFB scene or an extreme scene (namely, the network always has an abnormity), the time for restoring the synchronization of the network and the terminal can be shortened from 40s to 8s at most, and the time is shortened by 80%. The problem that terminal communication and data service are affected for a long time in the scene can be effectively solved, and therefore product experience of users is improved.
In an example, as shown in fig. 4, taking the first timer as T3511 as an example, a process of adjusting the set duration T of the timer T3511 is described, which includes:
step 401: and when detecting that the current scene meets the preset condition, the terminal initializes the set duration of the timer T3511 to T.
Here, the current scenario is an EPSFB scenario, i.e. voice fallback to 4G, supported by VoLTE to establish a voice call.
Here, the set time period T of the timer T3511 is initialized to 10 s.
Step 402: the terminal sends a cell registration request for the Nth time to the network equipment and controls a timer T3511 to start counting; when the counting time of the timer T3511 is less than or equal to the set time T, if the registration failure message sent by the network device is not received, execute step 403; otherwise, step 404 is performed.
Wherein, N is 1, …, M-1; m is an integer greater than 1.
Here, in the EPSFB scenario, after establishing the VoLTE voice call, the terminal needs to initiate a registration request to the 5G cell again.
Step 403: the terminal stops sending the cell registration request to the network device.
Step 404: the terminal adjusts the set time length T of the timer T3511 and continues to send the (N + 1) th cell registration request to the network device.
Here, M is equal to 5. The terminal initiates a cell registration request of the nth (N <5), and shortens the set time length T of the timer T3511 to 10-nx (10/5) to 10-nx 2 if receiving an RRC Release message issued by the network device.
Step 405: sending a cell registration request for the Mth time to the network equipment, stopping sending the registration request to the network equipment if receiving a registration failure message sent by the network equipment, and controlling a timer T3511 to start counting; and when the counting duration of the timer T3511 is equal to the preset duration, the terminal sends an M + M-th cell registration request to the network equipment.
Here, the preset time period is 12 min. m is a positive integer.
Step 406: in the process of sending the (M + M) th cell registration request to the network equipment, if a registration failure message sent by the network equipment is received, the set time length T of the timer T3511 is adjusted, and the (M + M + 1) th cell registration request is continuously sent to the network equipment.
Here, fig. 5 is a process of adjusting the set time period T of the timer T3511 when N is M, and includes:
step 501: the terminal determines the registration times N and the registration time threshold M of the current cell;
here, M is equal to 5.
Step 502: the terminal adjusts the set time period T of the timer T3511 to T- (M-1) × (T/M).
Here, the terminal initiates a cell registration request for the nth (N is 5), and if an RRC Release message issued by the network device is received, the terminal re-initiates cell registration for 5G after 12min, and if the current network still has an abnormality, the set duration T of the timer T3511 is adjusted to a fixed value, that is, 10- (5-1) × (10/5) ═ 2 s.
Here, adjusting the set time length T of the timer T3511 has the following advantages:
(1) after the terminal initiates a cell registration request, if the network device does not process the message, the network device directly issues registration failure messages such as RRC Release and the like, and in order to avoid the problem that the terminal and the network are out of step due to the registration failure, the set duration of the timer T3511 is adjusted, so that the terminal can be ensured to quickly recover normal voice call and data service, and the use experience of the user is ensured.
(2) The method for the nonstandard timer T3511 is provided, and before the cell registration times reach the total cell times, the set time length of the timer T3511 is kept to be a constant small value, so that the time for synchronizing the network and the terminal is shortened, the problem that the terminal call and the data service are influenced for a long time in the scene can be effectively solved, and the product experience of a user is improved.
In the third situation, if a registration failure message sent by the network device is received, the registration time threshold is adjusted to shorten the synchronization time of the terminal and the network.
Specifically, the threshold of the number of registrations may be adjusted to be small, and the set duration of the first timer may be kept unchanged. Or, the threshold of the registration times is adjusted to be small, the time interval of each cell registration is reduced along with the increase of the cell registration times before the cell registration of the terminal does not reach the threshold of the registration times, and the time interval of each cell registration is kept unchanged after the cell registration of the terminal reaches the threshold of the registration times.
In practical application, the terminal may need to try to perform cell registration for multiple times in a specific scenario, and if the cell registration time is too long, the synchronization time between the terminal and the network device is too long, so that the total number of cell registrations may be modified in order to shorten the synchronization time between the terminal and the network device.
Based on this, in an embodiment, adjusting the registration number threshold includes:
adjusting the registration time threshold value initiated to the network equipment from a first value to a second value;
wherein the first value is greater than the second value.
For example, taking the first timer T3511 as an example, assuming that the initial setting time length T of the timer T3511 is 10s and the registration time threshold M is 5 times, when the terminal initiates a cell registration request for the 1 st time to the network device, the timer T3511 starts to count, and when the counting time length of the timer T3511 is equal to 10s or less, if a registration failure message sent by the network device is received, the registration time threshold M is adjusted to M-1 being 5-1 being 4; when a terminal initiates a cell registration request for the 2 nd time to a network device, a timer T3511 starts to count, and when the counting duration of the timer T3511 is equal to a cell or 10s, if a registration failure message sent by the network device is received, a registration time threshold M is adjusted to be M-1-4-1-3; when the terminal initiates a cell registration request for the 3 rd time to the network device, the timer T3511 starts to count, and when the counting duration of the timer T3511 is equal to or less than 10s, if a registration failure message sent by the network device is received, the cell registration request is stopped from being sent to the network device because the registration time threshold has been reached.
In an example, as shown in fig. 6, taking the first timer as T3511 as an example, a process of adjusting the registration number threshold is described, which includes:
step 601: and when detecting that the current scene meets the preset condition, the terminal initializes the set duration of a timer T3511 to T.
Here, the current scenario is an EPSFB scenario, i.e. voice fallback to 4G, supported by VoLTE to establish a voice call.
Step 602: the terminal sends a cell registration request for the Nth time to the network equipment and controls a timer T3511 to start counting; when the counting time of the timer T3511 is less than or equal to the set time T, if the registration failure message sent by the network device is not received, execute step 603; otherwise, step 604 is performed.
Here, in the EPSFB scenario, after establishing the VoLTE voice call, the terminal needs to initiate a registration request to the 5G cell again.
Step 603: the terminal stops sending the cell registration request to the network device.
Step 604: the terminal adjusts the registration time threshold value initiated by the network equipment and continuously sends the (N + 1) th cell registration request to the network equipment.
Here, fig. 7 is a process of adjusting a threshold of the number of registrations initiated to a network device, including:
step 701: the terminal determines a registration time threshold value M initiated to the network equipment.
Step 702: and the terminal adjusts the registration time threshold value M initiated to the network equipment to be M-p.
Wherein p is a positive integer.
Here, adjusting the threshold of the number of registrations has the following advantages:
(1) after the terminal initiates a cell registration request, if the network device does not process the message, the network device directly issues registration failure messages such as RRC Release and the like, and in order to avoid the occurrence of the problem that the terminal and the network are out of step due to the registration failure, the threshold value of the registration times is adjusted to ensure that the terminal can quickly recover normal voice call and data service, thereby ensuring the use experience of the user.
(2) Under an EPSFB scene or an extreme scene (namely, the network is always abnormal), the registration time threshold is adjusted, so that the time for recovering the synchronization of the network and the terminal can be shortened, the problem that the terminal call and the data service are influenced for a long time under the scene is effectively solved, and the product experience of a user is improved.
By adopting the technical scheme of the embodiment of the invention, after the terminal tries the cell registration failure once, the success rate of the cell registration of the terminal is improved by adjusting the set time length T and/or the registration time threshold of the first timer, thereby shortening the time length of the synchronization of the terminal and the network equipment.
