Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in the various embodiments of the present application, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present application, and the embodiments may be mutually incorporated and referred to without contradiction.

An embodiment of the present application provides a signaling storm suppression method, as shown in fig. 1, including:

step 101, when monitoring that radio link control (RRC) connection abnormality occurs in at least two MA PDU sessions within preset time, stopping an RRC connection retry process of the at least two MA PDU sessions;

and 102, switching the service data of at least two MA PDU sessions to an available 3GPP channel or a non-3GPP channel in sequence for transmission.

The method for suppressing a signaling storm of this embodiment is applied to a mobile terminal, for example, a device such as a mobile phone and a tablet, where the mobile terminal is in communication connection with a network side to implement a network service, and the network side of this embodiment needs to support functions of Steering, switching, and offloading (referred to as "ATSSS") of Access Traffic. The atasss function is introduced by the 3gpp R16 release, and is mainly used for path optimization, seamless handover, multipath concurrence, and the like of a terminal multiple-Access (MA) service. Based on the ATSSS function, the mobile terminal may perform Data transmission with a network side through a multiple-Access Protocol Data Unit (MAPDU) session, where the MAPDU session may have multiple session channels, and the session channels are a third Generation Partnership Project (3 rd Generation Partnership Project, abbreviated as "3 GPP") channel and a non-3GPP channel, so that service Data of the session may be transmitted through multiple channel paths, and reliability of Data transmission is ensured.

In the prior art, as a large number of terminals are accessed to a network, the number of transmissions in the network is increased, and as the terminal service reasons, network jitter, sudden large-scale access and other situations, network signaling overload occurs, signaling channel resources of the terminals, which are accepted and managed by the network, are consumed, and finally, a network congestion or even a paralyzed signaling storm is caused. Therefore, it is desirable to minimize the inefficient transmission of signaling, prevent network congestion, and reduce the possibility of signaling storms in the communication network.

In this embodiment, the mobile terminal stops the retry process of the RRC connection of the at least two MA PDU sessions when it monitors that the RRC connection of the at least two MA PDU sessions is abnormal within the preset time, that is, when the RRC connection between the mobile terminal and the network side is abnormal, that is, the 3GPP channel cannot be used, the mobile terminal stops sending the signaling for reestablishing the RRC connection to the network side, so that the signaling transmitted in the 3GPP channel can be reduced, that is, the invalid signaling transmitted in the 3GPP channel is reduced, and the power consumption of the mobile terminal is reduced. The mobile terminal changes the channels used for transmitting the service data for each MA PDU session in sequence, so that the services in each MA PDU session can be continuously executed, invalid signaling transmitted in the 3GPP channels of the MA PDU session is reduced, the signaling storm possibility of a communication network is reduced, meanwhile, the service continuity in each MAPDU session is maintained, and the competitiveness of the mobile terminal is improved.

The details of the implementation of the method for suppressing a signaling storm according to the present embodiment are specifically described below, and the following description is only provided for the convenience of understanding, and is not necessary for implementing the present embodiment.

In step 101, the mobile terminal needs to monitor whether Radio Resource Control (RRC) of at least two MA PDU sessions is abnormal within a preset time, and immediately stop an RRC connection retry procedure of the MA PDU session in which the RRC connection is abnormal. The preset time may be 15 seconds, 10 seconds, 5 seconds, or 1 second, or a preset value may be input by the user. The RRC connection is abnormal, which includes but is not limited to: the mobile terminal sends the RRC connection request without receiving a response from the network side, the RRC connection request sent by the mobile terminal is rejected by the network side, the mobile terminal initiates RRC reestablishment, a Block Error Rate (BLER) of RRC connection is too high, and the like. The reason why the mobile terminal initiates RRC reestablishment generally is as follows: radio Link Failure (RLF), handover Failure (HO Failure), reconfiguration Failure (reconfiguration Failure), and the like. For example, when the RRC connection abnormality initiates RRC reestablishment for the mobile terminal, the mobile terminal monitors whether to send an RRC connection reestablishment message to the network side to identify the RRC connection abnormality. The mobile terminal may identify an MA PDU Session in which an abnormality occurs by identifying the PDU field in the RRC connection reestablishment message, for example, the RRC connection reestablishment message carrying the Session ID in the PDU field is as follows:

15:03:15.162 0xB821 NR5G RRC OTA Packet--UL_DCCH/RRC Connection Reestablishment

pdu-Session 1,

15:03:15.163 0xB821 NR5G RRC OTA Packet--UL_DCCH/RRC Connection Reestablishment

pdu-Session 2,

15:03:15.164 0xB821 NR5G RRC OTA Packet--UL_DCCH/RRC Connection Reestablishment

pdu-Session 3。

in one example, before step 101, the mobile terminal further needs to register in the 5G network supporting the sss, and establish a MAPDU session with the network side on the 3GPP channel and the non-3GPP channel, i.e., the 5G channel and the WiFi channel, respectively. The mobile terminal may determine whether the network supports the ATSSS function by detecting an ats _ ind field of a Registration Accept message sent by the 5G network side. The Registration Accept message content and ats _ ind fields are as follows:

15:03:10.219 0xB80A NR5G NAS MM5G Plain OTA Incoming Msg--Registration accept

nwk_feature_supp_inc＝1(0x1)

nwk_feature_supported

length＝2(0x2)

emf＝1(0x1)(Emergency srv fallback supported in NR connected to 5GCN only)

emc＝0(0x0)(Emergency srv not supported)

……

ats_ind＝1(0x1)。

after the MA PDU session is successfully established, whether the network side issues a Measurement Assistance Information message is monitored. If the Measurement Assistance Information message is monitored, the IP address and the port number of a network element with a Performance Measurement Function (PMF) on the network side are analyzed from the Measurement Assistance Information message. In the specification of 3gpp TS 24.193, the rule that the message of Measurement Assistance Information recorded in the Figure 6.1.5.2-1:

TABLE 1

And if the mobile terminal does not monitor the Measurement Assistance Information message within the monitoring time, the mobile terminal does not follow the steps of the signaling storm suppression method.

In step 102, the mobile terminal switches the service data of the MA PDU session to an available 3GPP channel or a non-3GPP channel in sequence for transmission. For example, when the RRC connection of three MAPDU sessions is abnormal, the mobile terminal first acquires an available 3GPP channel or a non-3GPP channel of a first MA PDU session, switches the service data of the first MAPDU session to the available 3GPP channel or the non-3GPP channel for transmission, then acquires an available 3GPP channel or a non-3GPP channel of a second MAPDU session, switches the service data of the second MA PDU session to the available 3GPP channel or the non-3GPP channel for transmission, and finally acquires an available 3GPP channel or a non-3GPP channel of a third MA PDU session, and switches the service data of the second MA PDU session to the available 3GPP channel or the non-3GPP channel for transmission. The sequencing of the three MA PDU sessions may be the sequence of the abnormal occurrence monitored by the mobile terminal, or may be any other sequencing, which is not limited in the present application.

In an example, the mobile terminal sequentially switches the service data of the at least two MA PDU sessions to an available 3GPP channel or a non-3GPP channel for transmission, which may be sequentially switching the service data of the at least two MA PDU sessions to a non-3GPP channel of the at least two MA PDU sessions, and specifies that all data packets of the MA PDU sessions are to be subsequently sent to the non-3GPP channel.

In this embodiment, since the session channel of the MA PDU session originally includes the 3GPP channel and the non-3GPP channel, the non-3GPP channel transmission path in the MA PDU session is used as the wireless transmission path, which can quickly obtain the available wireless transmission path of the MA PDU session, and reduce the processing delay of the MA PDU session switching channel, thereby reducing the possibility of signaling storm occurring in the communication network and maintaining the service continuity in each MA PDU session.

Further, before switching the service data of the at least two MA PDU sessions to the non-3GPP tunnel in the at least two MA PDU sessions in sequence, the mobile terminal further sends a tunnel change notification to the network side through the non-3GPP tunnel in the at least two MA PDU sessions, so that the network side updates the ATSSS rule table, where the ATSSS rule table is used to determine a tunnel used by the MA PDU session.

Specifically, the mobile terminal may inform the MA that the PDU session will use only the WiFi channel by sending a PDU session Modification Request message to the network side. The PDU session Modification Request message is as follows: "Traffic Descriptor: match-all", "Steering model: active-Standard, active = non-3GPP, standby =3GPP". According to the 3GPP TS 24.193 specification, the Steering Mode "Active-Standby" field in the PDU session Modification Request message is used to indicate the priority of the MA PDU session to use the specified channel. The mobile terminal preferentially uses the Active channel to transmit the service data, and uses the Standby channel as a transmission path to transmit the data when the channel is unavailable.

The coding specification of the Steering mode is described in Table 6.1.3.2-1.

TABLE 2

Table 6.1.3.2-1 in the 3gpp TS 24.193 specification, the encoding specification of the acid-standby mode in the stemering mode is described in the sss parameter inclusion an encoding ss rule, as shown in Table 3 below.

TABLE 3

In this embodiment, the mobile terminal sends the channel change notification to the network side before switching the MA PDU session to the non-3GPP channel in the MA PDU session, so that the network side can know the usage channel of the MA PDU session and update the ATSSS rule table.

In another example, the channel change notification sent by the mobile terminal to the network side according to the pre-obtained IP address and port number of the PMF network element may be a PMFP Access Report message, which informs the network side that the MA PDU session will only use the WiFi channel. Specifically, the mobile terminal may set the message content of the PMFP ACCESS REPORT message according to table6.2.1.4.1-1 in the 3GPP TS 24.193 specification as shown in the following table 4, so as to inform the network side of the availability of the 3GPP channel and the non-3GPP channel.

TABLE 4

Wherein, the content of the Access availability state needs to be generated according to the specification recorded in Figure 6.2.2.3-1 of the specification of 3GPP TS 24.193 to carry the available information of the 3GPP channel and the non-3GPP channel, as shown in the following tables 5 and 6:

TABLE 5

TABLE6

In one example, the mobile terminal further confirms that the network transmission quality of the transmission path of the non-3GPP channel in the at least two MA PDU sessions meets the preset requirement before switching the service data of the at least two MA PDU sessions to the non-3GPP channel in the at least two MA PDU sessions. The mobile terminal may measure the network transmission quality of the non-3GPP channel by testing an index, such as Round-Trip Time (RTT), a rate, a Received Signal Strength Indication (RSSI), a Signal-to-Noise ratio (SNR), etc., that indicates the network transmission quality, for example, when the RTT measured by the mobile terminal between the mobile terminal and the network side is less than a preset delay value, or when the Received Signal Strength measured by the mobile terminal is greater than a preset Signal Strength value, the mobile terminal considers that the network transmission quality of the non-3GPP channel transmission path meets a preset requirement, that is, the non-3GPP channel transmission path may be used as a data transmission path of the MA PDU session.

Specifically, when the mobile terminal selects to measure the RTT with the network side and measure the network transmission quality of the non-3GPP channel, the mobile terminal may send a PMFP Echo request message to the network side according to the specification of 3GPP TS 24.193, and receive PMFP Echo response information in which the network side replies to the PMFP Echo request message. The mobile terminal obtains the RTT value of this time by calculating the difference between the current value of the timer Tx in the PMFP Echo response message and the original value of the timer Tx in the PMFP Echo request message.

In this embodiment, before obtaining the non-3GPP channel transmission path of the MA PDU session, the mobile terminal determines that the network transmission quality of the non-3GPP channel transmission path meets the preset requirement, that is, when it is ensured that the network transmission quality of the non-3GPP channel transmission path of the MA PDU session is higher, the data transmission path of the MA PDU session is changed to the non-3GPP channel transmission path, so as to avoid that the data transmission path of the MA PDU session is changed to an invalid non-3GPP channel transmission path or a non-3GPP channel transmission path with poor network transmission quality, thereby ensuring the validity of the data transmission path change.

In another example, the service data of at least two MA PDU sessions are sequentially switched to an available 3GPP channel or a non-3GPP channel for transmission, and the service data of at least two MA PDU sessions may be sequentially switched to a 3GPP channel or a non-3GPP channel of a common PDU session in which no RRC anomaly occurs for transmission.

In this embodiment, by switching the service data of the MA PDU session to the 3GPP channel or the non-3GPP channel of the common PDU session in which the RRC anomaly does not occur for transmission, the service continuity in each MA PDU session can be maintained while reducing the possibility of signaling storm occurring in the communication network.
