Detailed ways

The technical solutions of the present invention will be further elaborated below with reference to the accompanying drawings and specific embodiments of the description.

As shown in FIG. 1 , this embodiment provides an information processing method, which is applied to a core network element, including:

Step S110: If the expected working duration of the PSM timer of the terminal is greater than the duration that can be provided by the network, send a prompt message for re-planning the duration of the PSM timer to the service platform corresponding to the terminal, wherein the PSM timer includes: the a first timer and a second timer;

Step S120: obtaining the PSM timer duration re-planned by the service platform based on the prompt information;

Step S130: Negotiate with the terminal according to the re-planned PSM timer duration, and re-determine the PSM timer duration.

The terminals may be various types of Internet terminals. After the terminal is attached to the network, it will negotiate with the network how long to maintain the radio frequency working mode this time. In the radio frequency working mode, the terminal requires the network side to reserve radio resources for it to send and receive data.

In this embodiment, the terminal has a PSM. In the PSM mode, the radio frequency chip of the terminal is turned off. This means that the terminal no longer receives and sends wireless signals, and thus no longer has the ability to communicate. At this time, the terminal is in a low-power state. power consumption mode, thereby reducing the power consumption of the terminal. The PSM mode is a type of radio frequency sleep mode. In the radio frequency sleep mode, the terminal neither receives nor sends wireless signals; in the radio frequency working mode, the terminal can send and receive wireless signals.

In some embodiments, the PSM timer includes: a first timer and a second timer, the duration of the first timer is the working duration of the terminal maintaining the radio frequency working mode; the duration of the second timer is The duration is the sleep duration during which the terminal maintains the radio frequency sleep mode; and/or the re-planned PSM timer duration includes: the suggested duration of the first timer and/or the suggested duration of the second timer; And/or, the re-determining the duration of the PSM timer includes: the negotiation duration of the first timer and the negotiation duration of the second timer. Step S110 may include: if the expected duration of the first timer of the terminal is greater than the duration that the network can provide, the core network element sends the prompt information to the service platform, and the service platform re-plans the PSM based on the prompt information The duration of the timer.

In the radio frequency working mode of the terminal and within the timing range of the first timer, the terminal can send various types of uplink information to the network side, for example, the uplink information includes but is not limited to uplink signaling; the uplink signaling may Including: uplink signaling that does not carry data, the uplink signaling can interact with the data between the communication network and may not be directly related to the service platform. For example, the uplink signaling that does not carry data may include: attach request, connection request, Connection flush configuration request, etc. The uplink signaling carrying data may include: various information that the terminal interacts with the service platform, for example, registration signaling for the terminal to register with the service platform, and the registration signaling may carry the terminal identity or user identity of the terminal. In some embodiments, the uplink information may further include: uplink data, which may not carry signaling but include various service data, for example, the metered water volume measured by a smart water meter.

In this embodiment, the PSM timer includes:

The first timer is used to count the time when the terminal is maintained in the radio frequency working mode. The duration of the first timer is: the duration that the terminal is maintained in the radio frequency working mode. If the first timer times out, the terminal switches from the radio frequency working mode to the radio frequency sleep mode, where the radio frequency sleep mode includes the PSM;

The second timer is used to count the time when the terminal is maintained in the radio frequency sleep mode. The duration of the second timer is: the duration that the terminal is maintained in the radio frequency sleep mode. If the second timer times out, the terminal switches from the radio frequency sleep mode to active model.

For example, the first timer may be T3324, and the second timer may be T3412; of course, only the first timer and the second timer in the terminal are illustrated here, and the specific implementation is not limited in the above example.

If in the process of negotiating the PSM timer duration between the terminal and the core network, it is found that the core network cannot meet the expected working duration of the first timer of the terminal. Here, the expected working duration of the first timer is the duration that the terminal expects to maintain in the radio frequency working mode. If the expected working duration of the first timer is longer, it indicates that the terminal needs to occupy the radio resources of the network for a longer duration. If there are a large number of IoT terminals in the network that apply to maintain the radio frequency working mode at the same time to occupy wireless resources, the frequency domain resources will be strained. At this time, a single terminal may not be able to occupy the wireless resources for a long time. The expected working duration of the first timer of the terminal.

At this time, the core network element sends prompt information to the service platform, and the prompt information will trigger the service platform to re-plan the duration of the PSM timer of the terminal. The core network element here includes but is not limited to at least one of the following: a mobility management entity (MME), an access management function (AMF), and the like.

After the service platform re-plans the PSM timer duration, the core network element may receive the re-planned PSM timer duration actively pushed by the service platform, or the core network element may actively read the re-planned PSM timer from the service platform. If the service platform actively pushes the re-planned PSM timer duration to the core network element, after the service platform completes the re-planning of the PSM timer duration, the service platform directly sends the re-planned PSM timer without being prompted by the core network element. The timer duration is sent to the core network element. If the core network element actively reads from the service platform, in addition to sending the above prompt information, the core network element may also send a read request to the service platform, and the service platform will re-plan the PSM timer based on the read request. The duration is returned to the core network element. In a word, there are various ways for the core network element to obtain the re-planned PSM timer duration from the service platform. Therefore, the step S120 may include: receiving the re-planned PSM timer duration pushed by the service platform; or, the core network element receiving the re-planned PSM timer duration from the service platform.

In this way, if the terminal and the core network negotiate the duration of the PSM timer and the network cannot be reselected to meet the terminal's requirements, the core network element will trigger the duration of the PSM timer through negotiation with the service platform corresponding to the terminal. In this way, the duration of the PSM timer after the renegotiation can enable different terminals to maintain the radio frequency working mode at different time periods, thereby reducing the congestion of information exchange between the terminal and the network side. Congestion of sending uplink data.

In some embodiments, the prompt information at least further includes at least one of the following:

The identification information of the terminal is used for the service platform to re-plan the duration of the PSM timer for the terminal;

The cell identification information of the cell to which the terminal is connected is used for the service platform to re-plan the duration of the PSM timer according to the cell status information of the cell to which the terminal is connected;

Network load status information, used for the service platform to re-plan the PSM timer duration according to the network load status;

The busy time period information of the network is used for the service platform to re-plan the duration of the PSM timer according to the busy time period of the network.

The terminal identification information includes but is not limited to: International Mobile Subscriber Identity (IMSI). The terminal identification information can facilitate the service platform to determine which terminal currently has the problem of negotiating the PSM timer, so that the duration of the PSM timer can be re-planned for the terminal in a targeted manner. For example, in some embodiments, the terminal identification information may further include: International Mobile Equipment Identity (IMEI)

In still other embodiments, if a batch of terminals in a certain cell request to maintain the radio frequency working mode in the same time period, the prompt information can also carry the group identification information of the work group corresponding to the batch of terminals, which is convenient for the service platform Through the re-planning of the PSM timers of different terminals in the working group, the re-planning of the PSM timers in a group is realized.

In still other embodiments, if a batch of terminals in a certain cell request to maintain the radio frequency working mode in the same time period, for the service platform, the wake-up time of the terminal is known. If the above prompt message appears, the service The platform can automatically adjust the wake-up time of some terminals, thereby increasing the duration of the first timers of some terminals. After the terminal is woken up, it is in the RF working mode.

However, if the prompt information carries terminal identification information, the duration of the PSM timer can be adjusted at the granularity of a single terminal, thereby reducing congestion caused by concurrent access of a large number of terminals to the network.

In some embodiments, the cell identification information of the cell connected to the terminal is sent to the service platform, so that the service platform can re-plan the duration of the PSM timer based on the cell status. The cell status may include: cell load rate change status information. In this way, the service The platform can adjust the duration of the PSM timer to make some terminals switch to the working state during the period when the cell load rate is low.

In some embodiments, the prompt information may further include: network load status information, the network load status information may include: information indicating the wireless network load status and/or information indicating the core network load status; in this way, it is convenient for the service platform According to the network load status information, the duration of the PSM timer is re-planned to reduce the situation that a large number of terminals concurrently access the network and use the network to transmit data in the same time period.

In some embodiments, the prompt information also carries information about the busy time period of the network, so that it is convenient for the service platform to determine the relatively free time period and/or the relatively busy time period of the network according to the busy time period information of the network. The re-planning of the duration of the PSM timer makes the time period when the terminal accesses or uses the network staggered from the busy time period to reduce congestion.

In some embodiments, the prompt information may carry at least terminal identification information, and the cell identification of the cell to which the terminal is connected, cell status information, network idle and busy period information, and/or network load status information can all be determined by the service The platform obtains from other information sources according to the network or cell where the terminal identification information is located.

In some embodiments, there are many ways to implement the step S130, and several optional ways are provided below:

Optional way 1: the step S130 may include: according to the re-planned PSM timer duration, taking the expected working duration of the first timer of the terminal as the negotiation duration of the first timer, and taking the duration greater than or less than the expected sleep duration of the second timer as the negotiation duration of the second timer.

If through negotiation, the core network promises to meet the expected working duration of the first timer of the terminal, but considering the congestion situation, it may be necessary to adjust the start time of the first timer. In this case, the duration of the second timer can be increased or decreased , so that the start time of the first timer of the terminal is staggered from the original start time. In this way, it is equivalent to adjusting the start and end time of the terminal maintaining the radio frequency working mode, thereby staggering the time period when other terminals request to access and use the network at the same time. , thereby alleviating congestion.

Option 2:

The step S130 may include:

According to the re-planned PSM timer duration, the negotiation duration of the first timer is set to be less than the expected working duration of the first timer of the terminal. In some cases, although the terminal applies for a longer duration in the radio frequency working mode, but the actual duration required for terminal data transmission (for example, uplink transmission) is shorter than the expected working duration of the first timer, then this In this case, the service platform may decide that the recommended duration of the re-planned PSM timer will be shorter than the expected working duration of the terminal. In this case, the terminal will also agree to remove the remaining duration reserved by the expected working duration. The first timer is set with a negotiation duration shorter than the expected working duration. In this way, communication according to the negotiation duration of the first timer can also reduce the duration of radio resources occupied by the terminal and relieve congestion.

In this embodiment, the negotiation duration of the second timer has no certain relationship with the expected working duration of the second timer. For example, the negotiation duration of the second timer may be equal to the expected working duration of the second timer. The working duration may also be shorter than the expected working duration of the second timer, or may be greater than the expected working duration of the second timer. In some embodiments, the service platform may set the negotiation duration of the second timer according to the requirement of the terminal for transmitting uplink information. Specifically, the core network element may set the second timer according to the suggested duration of the PSM timer. The negotiation duration of the timer.

Option three:

The step S130 may include:

According to the re-planned PSM timer duration, the expected working duration of the first timer of the terminal is taken as the negotiation duration of the first timer, and the expected sleep duration of the second timer is taken as the The negotiation duration of the second timer.

If the service level of the terminal is high or the equipment level of the terminal itself is high, it is necessary to give priority to meeting the needs of the terminal. If the prompt message carries the terminal identification information, the service platform may return the working duration of the re-planned PSM timer and the terminal. The expected working duration of the PSM timer is the same, then at this time, the core network element directly meets the needs of the terminal during the renegotiation process, and sets the negotiation duration of the first timer to the first timer according to the needs of the terminal. The expected working duration of the second timer is set, and the negotiation duration of the second timer is also set to the expected sleep duration of the second timer.

If the service level of the terminal is low and the device level of the terminal is also low, it may be necessary to make the negotiation duration of at least one timer not equal to the expected duration according to the first or the second option, so as to be compatible with the high service level or the high service level. Device-level terminations are staggered.

In some embodiments, the method further includes: receiving the next wake-up time of the terminal sent by the service platform;

The step S130 may include: negotiating with the terminal based on the next wake-up time and the re-planned PSM timer duration, and re-determining the PSM timer duration of the terminal.

In this embodiment, the next wake-up time may include but is not limited to at least one of the following: the next time the terminal reports data to the service platform, the next time the terminal registers to the service platform, the next time the terminal connects to the service The time when the platform will update the business rules. In a word, the next wake-up time can be the time when the terminal maintains the radio frequency working mode and accesses the network, and the network element and service platform on the network side can connect to the terminal.

For example, based on the distance between the next wake-up time and the current time, and whether the next wake-up time will be within the idle time period of the network, whether to adjust at least one of the durations of the first timer or/or the second timer through negotiation , or, to satisfy the desired duration required by the terminal.

In some embodiments, as shown in Figure 2, the method further includes:

Step S101: Receive the negotiation reference information sent by the service platform; Step S102: Forward the negotiation reference information to the terminal, wherein the negotiation reference information is used for the communication between the terminal and the core network element. PSM timer duration negotiation between

In some embodiments, the service platform will also send negotiation reference information to the terminal, where the negotiation reference information is used for the re-planned PSM timer duration based on the service platform when the terminal fails to negotiate for the first time in the core network. Negotiate again.

In some embodiments, the negotiation reference information may directly include: the PSM timer duration re-planned by the service platform, but is not limited to the re-planned PSM timer duration.

The negotiation reference information includes at least one of the following: the next wake-up time of the terminal; the load status information of the network; and the busy time period information of the network.

The negotiation reference information is helpful for the terminal to adjust the duration of the PSM timer in the process of determining the negotiation duration of the PSM timer, so as to increase the probability of successful re-negotiation of the PSM timer.

In some embodiments, the method further includes:

The next wake-up time of the terminal is sent to the core network element, so that the core network element and the terminal can negotiate the duration of the PSM timer.

In some embodiments, the next wake-up time may be sent to the core network element together with the re-planned PSM timer duration, or may be sent separately. In a word, the next wake-up time of the terminal is sent to the core network element, so that the core network element and the terminal can negotiate a more appropriate PSM timer duration, or increase the difference between the core network element and the terminal PSM timer duration. Negotiation success rate.

As shown in FIG. 3 , this embodiment provides an information processing method, which is applied to a business platform, including:

Step S210: Receive prompt information sent by the core network element, where the prompt information is: generated when the expected working duration of the PSM timer in the power consumption saving mode of the terminal is greater than the duration that the network can provide;

Step S230: Send the re-planned PSM timer duration to the core network element, where the re-planned PSM timer duration is used for the core network element and the terminal to perform the PSM timer. length of negotiation.

The information processing method provided in this embodiment is applied to the service platform, and the service platform needs to re-plan the duration of the PSM timer of the terminal based on the prompt information. The re-planned PSM timer duration will be sent to the core network element at least to assist the renegotiation of the PSM timer duration between the core network element and the terminal. The degree of congestion caused by accessing and using the network during the time period.

The prompt information comes from the core network element, and the prompt information may be generated by the core network element when it is determined that the network cannot provide the expected working duration of the terminal PSM timer and sent to the service platform.

The duration of the PSM timer is re-planned according to the busy period of the network corresponding to the busy period information of the network carried in the prompt information.

The business data that different terminals need to report are of different business types, and the urgency of business data of different business types is different. For example, for the monitoring data reported by smart water meters and smart pressure valves, one may only report water metering, and the other may be It is the reporting of safety data, so in this embodiment, the service platform will determine the service type based on the terminal identification information to re-plan the PSM timer duration. expected working hours. In some embodiments, the next wake-up time may be the time when the terminal enters the radio frequency working mode next time. If the next wake-up time is very close and the service level is not particularly high, delaying the terminal entering the radio frequency can also be considered. working mode time.

In a word, in this embodiment, the service platform will re-plan a PSM that can not only reduce the congestion degree, but also meet the needs of the terminal in consideration of various factors such as terminal conditions, service types, next wake-up time, and network conditions. Timer duration.

In some embodiments, the method further includes:

In this embodiment, the service platform also sends negotiation reference information to the terminal through the core network element, and the core network element can transparently transmit the negotiation reference information to the terminal. Of course, the core network element can also parse the negotiation reference. The information is then forwarded to the terminal, so that the terminal can renegotiate the duration of the PSM timer according to the negotiation reference information, so as to improve the success rate of the negotiation.

In some embodiments, the negotiation reference information includes at least one of the following: the next wake-up time of the terminal; the load status information of the network; and the busy period information of the network.

Several specific examples are provided below in conjunction with any of the above-mentioned embodiments:

Example 1:

When the IoT device is registered on the service platform, it provides the IMSI of the current device, and the service platform reads the cell ID of the cell accessed by the access device. This data reports the PSM timer requirement and the next service uplink time. After the service platform obtains the information, it informs the core network, and the core network negotiates the PSM duration with the terminal again, and negotiates different PSM durations with the terminal according to the data reporting requirements of the device, so as to avoid the congestion of uplink data.

The duration of the PSM timer of the current terminal is negotiated by the terminal and the core network, but when the terminal wakes up and performs data uplink after entering sleep is determined by the terminal as required. The congestion control of this scheme is accomplished with the help of these two time points. In the solution, when the terminal registers with the service platform, it reports its own IMSI. The IMSI is used when the core network queries the service data for information about a specific terminal, and can also be used for PSM timer negotiation.

The following is the PSM timer negotiation process when congestion occurs:

When the terminal and the core network negotiate the PSM duration, if the expected duration of the terminal is greater than the PSM duration provided by the core network, that is, the core network finds that the current signaling is congested and cannot provide enough interaction time, the core network synchronizes the IMSI of the device information. to the business platform.

The service platform reads the cell ID information (Cell ID) of the corresponding device, the time required for the terminal service, the next wake-up time and other information, and according to the current service type and expected working time of these devices and the cell where the current device is located next time. Re-plan the PSM duration of each terminal according to the online time.

The service platform notifies or actively reads the new PSM timer length calculated for the device by the core network.

The core network re-negotiates the PSM mode with each terminal according to the PSM timer duration suggested by the current service platform.

The service platform notifies the terminal of the estimated idle time of the network, and the terminal wakes up after this time and performs data exchange.

Through this process, the service platform obtains the cell identification information, service type, service demand duration and other information of the terminal that generates the uplink command, and calculates the estimated PSM timer duration of the target terminal device based on the uplink command requests of other registered devices in the same cell. The terminal PSM duration of the current target cell is dynamically adjusted based on the service conditions of other devices in the same cell, so as to solve the problem of uplink congestion. At the same time, the service platform can also provide the time for the device to wake up to perform the service according to the acquired information of the same cell device, so as to reduce the possibility of congestion.

In short, in this example, the core network uses the PSM timer duration to adjust the transmission time of uplink signaling, thereby reducing a large number of concurrent access conditions. The network reduces a large number of concurrent access of terminals. The service platform provides the next wake-up time of the terminal, which is beneficial to the negotiation of the duration of the PSM timer.

Example 2:

As shown in Figure 8, this example provides an information processing method, which can be used for the PSM timer duration negotiation method, including:

When the terminal requests to attach to the network, the core network will receive the Fuzhou request from the terminal;

The terminal registers with the service platform, for example, by registering with the service platform through a registration request carrying the IMSI;

After the terminal is attached to the network, the core network will negotiate the duration of the PSM timer with the terminal;

The service platform and the terminal obtain the cell identification information and the next wake-up time. The cell identification information and the next wake-up time here can be used to set different PSM timer durations for the terminals in the same cell, so as to realize batch wake-up. terminal, so that the terminal maintains the radio frequency working state.

The service platform re-plans the duration of the PMS timer according to the service type of the terminal;

The service platform notifies the core network of the re-planned PSM timer duration;

The terminal and the core network negotiate the duration of the PSM timer again.

The business platform notifies the terminal of the next wake-up time, so that the terminal can wake up on time at the next wake-up time and report data to the business platform.

The solution provided in this example can be used to solve the uplink congestion of NB-IoT terminals in large concurrency scenarios, and the solution provided in this example adjusts the wake-up time of terminals in large concurrency scenarios to avoid resource consumption caused by invalid wake-up of terminals, and reduce material consumption. Inactive power consumption of networked devices.

Figure 9 is a schematic diagram of state switching of a terminal. The terminal can enter the idle state from the connected state with a radio resource control (RRC) connection established with the network, and enter the idle state through the RRC connection release. After entering the idle state, the terminal activates the active time (Activetime). When it expires, it switches from the idle state to the PSM. In this way, the radio frequency mode of the terminal is equivalent to switching from the radio frequency working mode to the radio frequency sleep mode.

If the terminal has uplink information to be sent, it periodically performs tracking area update (TAU), exits PSM and switches to idle state, and switches to connected state through service request/TAU. If the terminal switches from the connected state to the idle state, the network side will also start the terminal to start the activation timer at the same time. The activation timer here may be one of the aforementioned first timers.
