Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before introducing the method, the apparatus, the storage medium, and the electronic device for controlling congestion of the internet of things provided by the present disclosure, an application scenario related to various embodiments of the present disclosure is first introduced. The application scene can be any one of the Internet of things such as NB-IOT, EMTC or MMTC. The terminal may be a mobile terminal such as a smart phone, a tablet computer, a smart television, a smart watch, a PDA (english: Personal Digital Assistant, chinese: Personal Digital Assistant), a portable computer, or a smart home device, for example: the floor sweeping robot comprises a floor sweeping robot, an air purifier, an air conditioner, a lighting lamp, a sound box, a robot and the like.
Fig. 1 is a flowchart illustrating a method for controlling congestion of an internet of things according to an exemplary embodiment, where the method is applied to a terminal, and includes the following steps:
For example, after the terminal initiates the first service flow to the internet of things, the internet of things judges whether the terminal can receive the first service flow according to the current network state. And if the current network state is a smooth state, the Internet of things receives the first business process and carries out corresponding operation according to the first business process. If the current network state is the congestion state, the Internet of things rejects the first service flow so as to perform congestion control, and sends rejection information including the first timing duration and the service type corresponding to the first timing duration to the terminal. The first timing duration can be understood as duration indicating that the terminal needs to back off (english: Backoff) or wait when the internet of things rejects the first service flow, and correspondingly, the service type corresponding to the first timing duration can be understood as a reason why the internet of things rejects the first service flow, that is, a type of congestion control currently performed by the internet of things.
The service type may include one or more service flows, which means that the internet of things does not receive any service flow included in the service type at present, and the terminal may send any service flow included in the service type again until the time indicated by the timing duration corresponding to the service type elapses. Each timing duration corresponds to a service type, which means that the terminal does not send any service flow included in the service type within the timing duration. The timing durations corresponding to the same service type may be the same or different. For example, the timing duration and the corresponding service type may be determined according to a rule agreed in advance by the terminal and the internet of things, or the timing duration and the corresponding service type may be determined by the side of the internet of things according to subscription information of the terminal and the current network state. Specifically, an identification code capable of uniquely identifying the service type can be allocated to each service type, when the internet of things rejects a certain service flow, the service type to which the service flow belongs is judged, the corresponding timing duration is determined, and finally the timing duration and the identification code corresponding to the service type are combined into rejection information to be sent to the terminal.
And step 102, updating a preset timing duration list according to the first timing duration.
And 103, determining a target timing duration according to the updated timing duration list, and starting a backoff timer according to the target timing duration.
For example, after acquiring the first timing duration, the terminal updates a preset timing duration list, where the timing duration list may be understood as a list stored on the terminal, where zero, one, or multiple records may be stored in advance, and each record includes the timing duration and a service type corresponding to the timing duration. The list of timed durations may be, for example, in the form of table 1:
TABLE 1
| Duration of time | Type of service |
| 25min | Type of modification |
| 10min | PDN connection type |
| 15min | Bearer activation type |
And finding out the target timing duration suitable for the current backoff timer to time from the updated timing duration list, and starting the backoff timer. Specifically, the manner of updating the timing duration list is different according to whether the backoff timer is currently timing, for example, if the backoff timer is not currently timing, which indicates that the timing duration list is currently empty, the first timing duration and the corresponding service type may be directly stored in the timing duration list, and the backoff timer is started according to the first timing duration, taking the first timing duration as the target timing duration. If the back-off timer is currently timing, it indicates that one or more records may be stored in the timing duration list, at this time, the back-off timer may be suspended, the first timing duration may be stored in the timing duration list, a target timing duration suitable for the current back-off timer to perform timing is found in the updated timing duration list, and then the back-off timer is restarted according to the target timing duration.
The method for selecting the target timing duration suitable for the current backoff timer may be to use the shortest timing duration in the updated timing duration list as the target timing duration, to select the most important timing duration of the service type in the timing duration list as the target timing duration according to the importance degree of the service type, to group a plurality of timing durations in the timing duration list, to use the longest timing duration in each group as the timing duration of the group, and to select the shortest timing duration from the plurality of groups as the target timing duration. Therefore, the timing duration of different service types can be realized by only setting a backoff timer on the terminal, thereby realizing different congestion control.
And 104, after the backoff timer is overtime, initiating a second service process to the Internet of things, wherein the second service process belongs to the service type corresponding to the target timing duration, and deleting the target timing duration from the timing duration list.
After the backoff timer is started, the terminal does not initiate various service flows (namely, second service flows) included in the service type corresponding to the target timing duration to the internet of things any more, and the terminal does not initiate the second service flows to the internet of things again until the backoff timer is overtime. And if the second service process is rejected by the internet of things again, repeating the step 101 to the step 104, namely, the terminal selects a new target timing duration again according to rejection information sent when the internet of things rejects the second service process, so that the backoff timer starts timing according to the new target timing duration.
It should be noted that, the business processes (including the first business process, and the second business process and the third business process described later) mentioned in the embodiments of the present disclosure may be: any one of a PDN (Packet Data Network, chinese) connection flow, a bearer activation flow, and a modification flow may be understood as a related flow of an ESM (english: EPS session management) layer.
Correspondingly, the service types can be divided into a plurality of types according to different service flows, namely all ESM flow types (namely including a bearer activation flow and a modification flow), PDN connection types (namely including a PDN connection flow), bearer activation types (namely including a bearer activation flow) and modification types (namely including a modification flow), and can also be divided into a plurality of types according to different Access ranges, namely the service flow types in the range of APN (Access Point Name, Chinese), the service flow types in the range of APN + P L MN (Public land Mobile Network, Chinese), further, the service types can also be divided into the ESM flow types in the range of APN, the PDN connection types in the range of APN, the bearer activation types in the range of APN, the modification types in the range of APN, the ESM flow types in the range of APN + P L MN, the ESM connection types in the range of PDN + P L MN, the PDN + P L and the modification types in the range of APN + P L.
In summary, in the present disclosure, after initiating the first service flow to the internet of things, if the internet of things rejects the first service flow, rejection information including the first timing duration and a service type corresponding to the first timing duration is sent to the terminal, where the corresponding service type includes the first service flow. And then, the terminal updates a preset timing duration list according to the first timing duration, determines a target timing duration according to the updated timing duration list, starts a backoff timer according to the target timing duration, initiates a second service process included in the service type corresponding to the target timing duration to the Internet of things after the backoff timer is overtime, and deletes the target timing duration from the timing duration list. Different congestion control of various service types can be realized only by arranging a timer on the terminal, and the resource consumption and the design cost of the terminal are reduced on the premise of ensuring accurate timing.
Fig. 2 is a flowchart illustrating another method for controlling congestion of the internet of things according to an exemplary embodiment, and as shown in fig. 2, the implementation of step 102 may include:
and step 1021, obtaining the remaining time length and the counted time length of the current backoff timer, and suspending the backoff timer, wherein the sum of the remaining time length and the counted time length is the counted time length of the backoff timer.
For example, if the terminal receives the rejection information for rejecting the first service flow, the back-off timer is counting time, which indicates that the terminal sent a certain service flow before, and is rejected by the internet of things, that is, the terminal needs to wait for the current timing duration of the back-off timer before continuing to send the service flow. In order to ensure that the current timing duration of the backoff timer can be normally timed and also accurately complete the timing of the first timing duration, the remaining duration and the timed duration of the current backoff timer may be recorded first, and the backoff timer may be paused at the same time. For example, if a terminal sends a certain service flow before, and is rejected by the internet of things and needs to retreat for 5min, the timing duration of the retreat timer is 5min, after 3min, the first service flow initiated by the terminal is rejected, and then the timed duration of the retreat timer is recorded for 3min and the remaining duration is recorded for 2 min.
Then, each timing duration in the timing duration list is updated by the counted duration, which can be understood as that each timing duration in the timing duration list is also timed in the process of executing timing by the backoff timer, and each timing duration in the timing duration list also times the counted duration when the backoff timer is paused. And then, storing the residual time length and the first timing time length into a timing time length list.
Specifically, step 1022 may be implemented according to the following steps:
firstly, the difference value between each timing duration and the timed duration in the timing duration list is obtained.
And then updating the timing duration into a difference value.
For example, when the terminal receives the reject message of the first service flow, the timing duration list includes 3 timing durations, as shown in table 2:
TABLE 2
| Duration of time | Type of service |
| 25min | ESM flow type |
| 15min | PDN connection type |
| 18min | Bearer activation type |
The current back-off timer is timing, the timing duration is the second timing duration in the timing duration list, namely 15min, at this time, it is equivalent to three timing durations which are simultaneously timing, and the terminal cannot initiate a service flow included in the PDN connection type, the ESM flow type or the bearer activation type. If the backoff timer has been started for 6min, that is, the remaining duration is 9min and the counted duration is 6min, the first timing duration included in the rejection message is 5min, and the corresponding service type is the modification type. Subtracting the timed length from each timed length in the timed length list, and storing the remaining time length and the first timed length into the timed length list to obtain a table 3:
TABLE 3
| Duration of time | Type of service |
| 19min | ESM flow type |
| 9min | PDN connection type |
| 12min | Bearer activation type |
| 5min | Type of modification |
Correspondingly, the implementation manner of step 103 may be:
and determining the minimum timing duration in the updated timing duration list as the target timing duration.
For example, the minimum timing duration is selected from table 3 as the target timing duration, that is, the fourth timing duration is 5min, and the back-off timer is started again according to the timing duration of 5 min. If the terminal receives the rejection information again within 5min, the steps 102 to 103 are repeated, the timing duration list is updated, and a new target timing duration is selected. If the terminal does not receive the rejection information within 5min, and the backoff timer is overtime after 8min, the terminal may initiate a service flow included in the service type corresponding to the fourth timing duration, that is, a modification flow included in the modification type, to the internet of things. And simultaneously, deleting 5min from the timing duration list, and updating each timing duration in the timing duration list according to 5 min. Table 4 was obtained:
TABLE 4
| Duration of time | Type of service |
| 14min | ESM flow type |
| 4min | PDN connection type |
| 7min | Type of modification |
And then the backoff timer is started according to the minimum timing duration in the updated timing duration list (namely table 4) as a new target timing duration (namely a second timing duration, 4 min). And pushing the class until all the timing durations in the timing duration list are overtime, namely the timing duration list is empty, the backoff timer is not started any more, the terminal is not subjected to congestion control by the Internet of things any more at the moment, and the service process in any service type can be initiated.
Fig. 3 is a flowchart illustrating another method for congestion control of the internet of things according to an exemplary embodiment, where the method further includes, as shown in fig. 3:
and 105, before the backoff timer is overtime, if a third service process needs to be initiated, determining whether the service type corresponding to the second timing duration in the updated timing duration list comprises the third service process.
And step 106, if the second timing duration exists, not initiating the third business process.
And 107, if the second timing duration does not exist, initiating a third business process to the Internet of things.
For example, in the process of timing by the backoff timer, if the terminal needs to initiate a third service flow, it needs to query whether a service type corresponding to the second timing duration includes the third service flow in the timing duration list, which may be understood as whether the internet of things performs congestion control on the terminal before the current time and indicates whether the duration for performing backoff (or waiting) by the terminal has been counted. If the second timing duration exists, the internet of things still performs congestion control on the service type corresponding to the second timing duration of the terminal, and if the second timing duration does not exist, the internet of things does not perform congestion control on the service type corresponding to the second timing duration of the terminal any more, and a third service process can be initiated.
Fig. 4 is a flowchart illustrating another method for congestion control of the internet of things according to an exemplary embodiment, where as shown in fig. 4, the method may further include the following steps:
and 108, when the terminal is powered off, recording the first system time, the remaining time length and the timed length of the current backoff timer, wherein the sum of the remaining time length and the timed length is the timed length of the backoff timer.
And step 109, acquiring the current second system time after the terminal is started.
And step 110, updating the timing duration list according to the first system time, the second system time, the remaining duration and the counted duration.
In a specific application scenario, a scenario that the terminal is powered off during the timing of the back-off timer may occur, and in order to ensure that the terminal is also accurately timed during the power-off, the system time (i.e., the first system time) when the terminal is powered off and the remaining duration and the timed length of the current back-off timer may be recorded. And then, the system time (namely the second system time) after the terminal is started is obtained, at this time, how long the terminal is stopped can be determined according to the first system time and the second system time, and the timing duration list is updated according to the remaining duration and the timed duration, so that the backoff timer can determine the target timing duration according to the updated timing duration list and start timing.
For example, when the terminal is powered off, the timing duration list includes 3 records, that is, 3 timing durations and corresponding service types. As shown in table 5:
TABLE 5
| Duration of time | Type of service |
| 50min | Bearing laserType of living |
| 30min | PDN connection type |
| 39min | Type of modification |
The timing duration of the current backoff timer is the second timing duration 30min in the timing duration list, when the backoff timer times to 18min, the counted duration is 18min, the remaining duration is 12min, the terminal is powered off, and the power-off time is 12: 20, the time of the terminal powering on is 12: 47. it can be obtained that the terminal has been powered off for 27 min. Then subtracting 18min from each timing duration in the timing duration list, and then subtracting 27min, then updating the first timing duration to 15min, the second timing duration is over time, and from the mountain area in the timing duration list, the third timing duration is updated to 4min, to obtain table 6:
TABLE 6
| Duration of time | Type of service |
| 15min | Bearer activation type |
| 4min | Type of modification |
Then the minimum timing duration (i.e., 4min) may be selected in table 6 as the target timing duration and the back-off timer is started to start timing. Therefore, the terminal can be ensured to accurately time when being powered off.
In summary, in the present disclosure, after initiating the first service flow to the internet of things, if the internet of things rejects the first service flow, rejection information including the first timing duration and a service type corresponding to the first timing duration is sent to the terminal, where the corresponding service type includes the first service flow. And then, the terminal updates a preset timing duration list according to the first timing duration, determines a target timing duration according to the updated timing duration list, starts a backoff timer according to the target timing duration, initiates a second service process included in the service type corresponding to the target timing duration to the Internet of things after the backoff timer is overtime, and deletes the target timing duration from the timing duration list. Different congestion control of various service types can be realized only by arranging a timer on the terminal, and the resource consumption and the design cost of the terminal are reduced on the premise of ensuring accurate timing.
