Detailed Description
The technical scheme of the invention is further elaborated below by referring to the drawings in the specification and the specific embodiments.
As shown in fig. 1, this embodiment provides an access control method, including:
Step S110: when the network load of a core network or an access network accords with an overload condition or the congestion condition of the core network or the access network accords with a congestion condition, an access network element sends indication information of an access restriction rule to User Equipment (UE);
wherein the access restriction rule comprises at least one of:
The access mode used by the UE is forbidden;
the UE type of forbidden access;
the type of service that is barred from access.
The accounting control method provided in this embodiment is a method applied to a network side, for example, a method applied to a network element of an access network, for example, a method in an evolved Node B (eNB). The Access network element may be the eNB or a next generation base station (next generation Node B, gnb) or other wireless Access node (AP), etc.
The step S110 in this embodiment may include:
Step S111: when the network load of the core network or the access network accords with an overload condition or the congestion condition of the core network or the access network accords with a congestion condition, acquiring indication information matched with the overload condition or the congestion condition of the access network or the core network;
step S112: and sending the indication information to the UE.
The manner of obtaining the indication information may be 2 the access network element, which generates the indication information itself according to the load condition or congestion condition of the access network or the core network, or may also be received from the core network element, for example, from a Mobility management entity (Mobility MANAGEMENT ENTITY, MME).
For example, a correspondence between the load factor or congestion status and the corresponding indication information is preset in the network element forming the indication information, and when the indication information required to be issued to the UE is formed, the corresponding relationship is queried according to the current information such as the load factor and the congestion status, and the indication information matched with the information such as the load factor and the congestion status in the correspondence is selected as the indication information required to be issued to the UE currently. Of course, the manner of generating the indication information is not limited to the above examples.
When the network load of the core network or the access network meets the preset condition, the method may include: when the load rate of the access network or the core network reaches the load rate threshold or the load capacity exceeds the load capacity threshold, the network load of the core network or the access network can be considered to accord with the overload condition. In this embodiment, determining the network load of the core network may include determining whether a current load rate or a current load amount of the MME reaches a corresponding threshold. The network load of the access network meets the overload condition, and may include: and judging whether the current load rate or the load capacity of the base station reaches a corresponding threshold.
The congestion status of the core network or the access network can be represented by the load status of the current core network or the access network, or can be represented according to the available resource status of the current network or the number of requests to be responded and other parameters, and when the congestion status meets a certain condition, the core network or the access network can be considered to be congested, and the congestion needs to be relieved. For example, the number of requests to be responded in the current MME or eNB queue exceeds a number threshold, or the usage of processing resources of the current MME or eNB reaches an upper usage limit, etc., so that congestion can be considered to occur, and the congestion condition is met.
At this time, the access network element sends indication information to all UEs covered by the access network element through a broadcast message. The indication information may be used to indicate the validation or enforcement of the access restriction rules.
In this embodiment, the access network element sends indication information to the UE, and may send the UE through a broadcast message or a non-broadcast message.
The broadcast message may include a system message. The indication information may be transmitted to the UE carried in a master device information block (Master Information Block, MIB) or a system information block (System Information Block, SIB) of a system message.
The access restriction rule indicated by the indication information in this embodiment may include:
The access mode used when the UE is forbidden to access;
The type of UE that is barred from access, which can be distinguished by UE capabilities of the UE, can be specifically: indicating which UEs with which UE capabilities are barred from access.
The type of service that is barred from access.
The indication information can be divided into three types of indication bits, namely a first type indication bit, a second type indication bit and a third type indication bit; one or more bits in the first type of indication bits are used for indicating an access mode of forbidden access, and the second type of indication bits are used for indicating a UE type of forbidden access; the third class indication bit is used for indicating the service type of forbidden access. In this embodiment, the indication bits corresponding to the indication information are split into three types for characterization, so that when the access restriction rule takes effect, the execution of the access restriction rule conforming to the current network condition can be flexibly combined by combining at least two types of indication bits. And the current effective access limit rule is indicated through the sending of the indication information, but not the complete access limit rule is sent, and the method has the characteristics of small signaling overhead and high flexibility.
After receiving the indication information, the UE knows which restricted access rules are currently effective, and before initiating access, the UE needs to determine whether to allow the UE to initiate access according to the access restricted rules effective in the current period.
In some embodiments of the present invention, in some embodiments,
The method for prohibiting the UE from using the access mode comprises at least one of the following steps:
the control plane optimizes the CP mode of data transmission;
the user plane optimizes the UP mode of data transmission;
a wireless resource control connection establishing legacy mode;
the access-prohibited UE types include at least one of:
Only supporting the UE accessed by the CP mode;
Simultaneously supporting the UE entering the CP mode and the UP mode;
the service types of the forbidden access include at least one of the following:
calling data service mo-data;
calling meta-data mo-Exception Data;
Delay tolerant access service Delay Tolerant Access;
Calling signaling service mo-signaling;
network protocol IP data traffic;
non-IP data traffic.
The CP method includes: the terminal directly transmits the data to the MME through control plane signaling, for example, a Non-access stratum (NAS) message, and the MME forwards the data to the external network instead of forwarding the data to an access mode of the external network through a gateway. The CP method requires the MME to participate in data transmission, and if the CP method accesses too many UEs, overload or congestion of the MME may be caused.
The UP mode is as follows: before the connection between the UE and the network side is released, the network side stores the historical context of the UE, and when the terminal initiates connection with the network side next time, the stored context is used for establishing the access mode of the connection. In the access mode, the access network elements such as the base station are required to store the context, if the accessed UE is too many or the stored context is too many, the cache resource is reduced, and in the next access, the context stored in the previous time may be required to be searched, and a certain processing resource is required to be consumed. Processing resources herein may include computing, querying, and retrieving resources provided by a processor or processing circuitry.
The legacy mode is a mode of establishing connection by using RRC signaling.
The mo-exception data is generally directed to burst type traffic, such as alarm traffic, abnormal type data reporting traffic, etc.
The network protocol IP data service may be simply referred to as a non-IP-data service; the network protocol IP data traffic may be referred to as IP-data traffic. The data packet corresponding to the non-IP-data service usually does not carry the destination IP address, and the route forwarding not based on the destination IP address is adopted. The data packet corresponding to the IP-data service is carried with
For the limitation of the CP mode, generally, when the network load of the core network meets the overload condition or the congestion condition load of the core network, especially when the current condition load of the MME meets the overload condition or the congestion condition, the indication information sent by the access network element may be used to instruct to prohibit some or all terminals from initiating access in the CP mode, or instruct all or some services to initiate access in the CP mode to take effect by using an access limitation rule, thereby alleviating the overload or congestion condition of the core network.
For the limitation of the UP mode, generally, when the network load of the access network accords with the overload condition or the congestion condition of the access network accords with the congestion condition, especially when the residual buffer of the base station is smaller than a buffer threshold, or the buffer is tense, or the residual processing resource is smaller than a processing resource threshold, and the like, the indication information sent by the network element of the access network is used for indicating to prohibit all or part of terminals from being accessed in the UP mode or all or part of services from being accessed in the UP mode, the access limitation rule of all or part of services from being accessed in the UP mode is effective, thereby relieving the overload or congestion condition of the access network.
The type of the UE in this embodiment is determined according to the UE capability of the access mode supported by the UE. For example, the UEs may be classified into one type of UEs supporting only the CP mode, while supporting another type of UEs supporting both the CP mode and the UP mode.
The indication information may indicate that the corresponding access restriction rule takes effect, thereby restricting access of a certain type of UE. For example, the access network element may indicate, through the second type indication bit, that an access restriction rule prohibiting access of a UE supporting only the CP mode is validated when congestion or overload occurs in the core network. For another example, the access network element may instruct, through the second type bit, to prohibit access by the UE supporting both the CP mode and the UP mode when congestion or overload occurs in the access network, or instruct access by the UE adopting both the CP mode and the UP mode.
Specifically, the indication information indicates that the effective access restriction rule may include at least one of: rule 1: the calling of calling data service mo-data, calling supernormal data mo-ExceptionData, delay tolerant access service delayTolerantAccess or calling signaling service mo-signaling is forbidden to be initiated by using an UP mode or a legacy mode;
Rule 2: disabling the call originating of said mo-ExceptionData, said delayTolerantAccess, or said mo-signaling using CP mode;
Rule 3: prohibiting a predetermined proportion of UEs from initiating the mo-data call using a CP manner;
Rule 4: prohibiting a UE supporting only a CP mode from initiating a call of the mo-data, the mo-ExceptionData, the delayTolerantAccess or the mo-signaling;
Rule 5: the UE supporting the CP mode and the UP mode simultaneously is forbidden to initiate the call of the mo-data, the mo-ExceptionData, the delayTolerantAccess or the mo-signaling;
rule 6: the UE supporting the CP mode and the UP mode simultaneously is forbidden to initiate the call of the mo-data, the mo-ExceptionData, the delayTolerantAccess or the mo-signaling by using the CP mode;
Rule 7: the UE supporting the CP mode and the UP mode simultaneously is forbidden, and the UP mode or the legacy mode is used for initiating the call of the mo-data, or the mo-ExceptionData, the delayTolerantAccess or the mo-signaling;
Rule 8: prohibiting sending non-network protocol data non-IP-data service;
Rule 9: prohibiting transmission of the non-IP-data service of which the single data packet exceeds a first preset data packet length threshold, the non-IP-data service of which the cumulative transmission data amount of one connection is larger than a first accumulation threshold, the non-IP-data service of which the traffic exceeds a first preset traffic threshold, or the non-IP-data service with continuous data packets, wherein the non-IP-data service with continuous data packets is that: the non-IP-data service of a plurality of data packets is sent through one connection;
Rule 10: forbidding sending network protocol data IP-data service;
Rule 11: the transmission of the IP-data service of which the single data packet exceeds a second preset data packet length threshold, the connection of the IP-data service of which the accumulated data quantity is larger than the second accumulation threshold at one time and the connection of the IP-data service of which the flow exceeds a second preset flow threshold are forbidden;
Rule 12: the CP mode is forbidden to be used for initiating the service exceeding the third preset data packet length threshold, the service of which the one-time connection accumulated data volume exceeds the third accumulation threshold, the service of which the flow exceeds the third preset flow threshold or the service with continuous data packets;
Rule 13: and prohibiting to initiate the service below the fourth preset data packet length threshold, the service with the accumulated data quantity of one connection below the fourth accumulation threshold or the service with the flow quantity below the fourth preset flow threshold by using an UP mode.
The preceding ordinal words "first", "second", and "third" before the predetermined packet length threshold and the accumulation threshold are all used to distinguish the thresholds in different situations, and do not represent a substantial meaning.
In this embodiment, the access network element may instruct the corresponding access restriction rule to take effect according to the current location of congestion status or overload phenomenon and according to the effect of restricting access by the access restriction rule.
In this embodiment, the foregoing multiple access restriction rules may be pre-stored in the UE and the access network element, or may be pre-negotiated for the UE and the access network element, or may be pre-specified by a communication protocol. In summary, before the indication information is sent, the access network element and the UE may have corresponding ways to obtain the access restriction rule, and obtain a correspondence between the indication information and the access restriction rule, so that a subsequent UE may execute or take effect of executing the specific access restriction rule according to the indication information, thereby implementing access control, and alleviating overload or congestion caused by accessing a large number of UEs, especially, terminals of the internet of things, to the network at the same time.
For example, when the indication information indicates that the rule 3 is effective, the UE randomly generates a random number between 0 and 1 before initiating access, compares the random number with the predetermined ratio, and allows the UE to initiate access if the random number is greater than the predetermined ratio, otherwise prohibits the UE from initiating access. Of course, if the random number is not greater than the predetermined try, the UE may be allowed to initiate access, otherwise, the UE is forbidden to access.
The above is merely an example of an access restriction rule, but the specific implementation is not limited to any one of the above rules.
In this embodiment, the access restriction rule may be divided into two parts, where the first part is rule content and the second part is restriction parameter of rule execution. The limiting parameters may include one or more of time parameters, scale parameters, and data model parameters, although specific implementations may include exception parameters, etc. The exception parameters herein may correspond to at least which special cases correspond to cases where the rule content is not valid. Optionally, the access restriction rule further includes at least one of a time parameter, a scale parameter, and a data model parameter;
the time parameter is used for specifying the effective duration of the access limiting rule;
The proportion parameter is used for indicating the proportion of the user equipment for limiting access or the effective probability of the access limiting rule;
The data model parameters include: a data model threshold;
the data model threshold comprises at least one of the following;
a packet length threshold;
An accumulation threshold for accumulating the amount of data;
a flow threshold;
A data number threshold of the continuous data packet;
A transmission frequency or period threshold of consecutive data packets.
The validation period corresponds to a time length of a time window. If the UE receives the indication information, reads the rule content of a certain access restriction rule, extracts the time parameter, and calculates the effective time from the moment of receiving the indication information or from the moment of reading the access restriction rule according to the effective time of the restriction in the time parameter. The proportion parameter indicates the effective probability of one or more rules or the proportion of the user terminal. When the proportion parameter is the proportion of the accessed UE, the UE can generate a random number, compare the random number with the proportion and then determine whether to initiate an access request currently.
In this embodiment, the limiting parameters may be individually written in each of the access limiting rules, and the limiting parameters may be shared by multiple limiting rules at the same time. For example, the time parameter may be a parameter that is shared by multiple access restriction rules. The time parameter may be sent to the UE by the base station, or may be indicated to the UE by the base station.
The step S110 may further include:
The access network element sends the indication information to the UE through a broadcast message, wherein the broadcast message comprises: system messages.
In other embodiments, the step S110 may include:
the access network element sends the indication information through paging information, a physical downlink control channel or dedicated RRC signaling.

And if the access request is not initiated temporarily, controlling the initiation of the access request according to the indication information.
In short, the access network element may send the indication information to the UE in various manners, and is not limited to any one of the foregoing manners.

(1) Prohibiting the call of mo-data, or mo-ExceptionData, or delayTolerantAccess, or mo-signaling from being initiated by using the UP mode or the legacy mode;
(2) The call of mo-ExceptionData, delayTolerantAccess or mo-signaling is forbidden to be initiated by using the CP mode;
(3) A certain proportion of X UE (user equipment) is forbidden to initiate mo-data call by using a CP mode;
(4) A UE with the device capability of supporting the CP mode only is prohibited from initiating a call of mo-data, or mo-ExceptionData, or delayTolerantAccess, or mo-signaling;
(5) A UE with the device capability of supporting the CP mode and the UP mode simultaneously is prohibited from initiating a call of mo-data, mo-ExceptionData, delayTolerantAccess or mo-signaling;
(6) The UE with the device capability of supporting the CP mode and the UP mode simultaneously is prohibited from initiating a call of mo-data, mo-ExceptionData, delayTolerantAccess or mo-signaling by using the CP mode;
(7) The UE with the device capability of supporting the CP mode and the UP mode simultaneously is prohibited from initiating a call of mo-data, mo-ExceptionData, delayTolerantAccess or mo-signaling by using the UP mode or the legacy mode;
(8) Prohibiting sending non-IP-data service;
(9) Prohibiting transmission of non-IP-data service exceeding a preset data packet size threshold, or non-IP-data service exceeding an accumulated data volume threshold, or non-IP-data service exceeding a preset traffic volume threshold, or non-IP-data service with continuous data packets;
(10) Inhibit sending IP-data traffic;
(11) The transmission of the IP-data service exceeding the preset data packet size threshold, or the IP-data service exceeding the accumulated data volume threshold, or the IP-data service exceeding the preset traffic volume threshold is forbidden;
(12) The method comprises the steps that a CP scheme is forbidden to initiate a service exceeding a preset data packet size threshold, a service exceeding an accumulated data volume threshold, a service exceeding a preset flow threshold or a service with continuous data packets, wherein the threshold can be notified to UE by a network side or preset by a transceiver;
(13) The UP scheme is prohibited from being used to initiate traffic below a preset packet size threshold, or traffic below a cumulative data volume threshold, or traffic below a preset traffic threshold (meaning that the UP mode is prohibited from being used to transmit small data/small traffic because the UP scheme is suitable for transmitting large data/large traffic).
The eNB selects a type 1 rule or a plurality of rules without mutual conflict from the access limiting rules according to the severity level of the self-load condition and the main reason causing the load; for example the following examples:
Taking 1 rule as an example:
Example 1: selecting rule (1), wherein the selected limited service type is delayTolerantAccess, and the eNB comprises the following instructions in RRC connection rejection signaling, RRC connection reestablishment rejection signaling or RRC connection release signaling:
The UP mode or the legacy mode is forbidden to initiate delayTolerantAccess calls;
When the UE receives the instruction and initiates delayTolerantAccess services, the UE can only initiate access by using methods other than an UP mode and a legacy mode according to the instructed access limit rule;
example 2: still select rule (1), the selected restricted service types are mo-data and delayTolerantAccess, and the eNB includes the following indication in RRC connection reject signaling, RRC connection reestablishment reject signaling, or RRC connection release signaling:
The call of mo-data or delayTolerantAccess is prohibited to be initiated by using the UP mode or the legacy mode;
When the UE receives the instruction, and initiates delayTolerantAccess service or mo-data service, according to the instructed access limit rule, the UE can only initiate access by using methods other than the UP mode and the legacy mode.
Example 3: still selecting rule (1), and selecting restricted service types mo-ExceptionData and mo-signaling, and mo-data and delayTolerantAccess, the eNB includes the following instructions in RRC connection reject signaling, RRC connection reestablishment reject signaling, or RRC connection release signaling:
Prohibiting the call of mo-data, or mo-ExceptionData, or delayTolerantAccess, or mo-signaling from being initiated by using the UP mode or the legacy mode;
the UE receiving the instruction can initiate access only by using methods other than the UP method and the legacy method when it initiates the 4 services limited by the rule.
Example 4: the usage of rule 2 can be referred to rule 1, see examples 1,2,3;
Example 5: a selection rule (3), wherein the selected limited service type is mo-data, and the eNB comprises the following instructions in RRC connection rejection signaling, RRC connection reestablishment rejection signaling or RRC connection release signaling:
A certain proportion of X UE (user equipment) is forbidden to initiate mo-data call by using a CP mode; the ratio X may be configured by the eNB to notify the UE by a broadcast message or dedicated signaling, for example: when the load is heavy, the ratio X may be set higher, for example 80%.
When the UE receives the indication, the UE can directly initiate access by adopting other methods except the CP mode when the UE initiates the mo-data service limited by the rule, if the CP mode is adopted, the probability of initiating the access by the UE is calculated according to uniformly distributed random numbers, and when the proportion X is 80%, only 20% probability can initiate the access by using the CP mode.
Example 6: selection rule (4)
A UE with a device capability of "CP-only mode" is prohibited from initiating a mo-data, or mo-ExceptionData, or delayTolerantAccess, or mo-signaling call.
The rule limits the type of capability and the type of initiated service that the UE has, and besides the capability limitation, the limitation of the service may select various free combinations, such as:
A UE with the equipment capacity of 'supporting only a CP mode' is prohibited from initiating a mo-data call;
A UE with the device capability of 'supporting only a CP mode' is prohibited from initiating delayTolerantAccess calls;
A UE with the device capability of supporting the CP mode only is prohibited from initiating a call of mo-ExceptionData or mo-signaling;
a UE with the equipment capacity of 'supporting only a CP mode' is prohibited from initiating a mo-signaling call;
Example 7: selection rule (5)
A UE with a device capability of "supporting both CP and UP modes" is prohibited from initiating a call of mo-data, or mo-ExceptionData, or delayTolerantAccess, or mo-signaling. The rule sets access restrictions on another UE capability; reference example 6 can be made to the usage;
example 8: selection rule (6)
A UE with a device capability of "supporting both CP and UP modes" is prohibited from initiating a mo-data, or mo-ExceptionData, or delayTolerantAccess, or mo-signaling call using the CP mode.
The rules contain 3 constraints on UE capabilities, access method used, and type of service initiated, the use method can refer to the previous example;
example 9: selection rule (7)
The UE with the device capability of supporting the CP mode and the UP mode simultaneously is prohibited from initiating a call of mo-data, mo-ExceptionData, delayTolerantAccess or mo-signaling by using the UP mode or the legacy mode;
similar to rule 6, except that the constraints on the access method used are different;
Example 10: selection rule (8)
Prohibiting sending non-IP-data service;
The rule only limits access to the service types, and aims at the services which are not based on the IP address transmission technology, and the services are transmitted in a CP mode in the current LTE protocol.
The UE receiving the rule can not initiate access as long as the UE initiates non-IP-data service, no matter what the capability is and no matter what access method is adopted;
example 11: selection rule (9)
Disabling transmission of non-IP-data traffic exceeding a preset packet size threshold, or non-IP-data traffic exceeding a cumulative data size threshold, or non-IP-data traffic exceeding a preset traffic threshold, or non-IP-data traffic with consecutive packets
The rule has looser access constraints on non-IP-data traffic than rule (8), and limits access to a portion of non-IP-data traffic from the point of view of traffic data characteristics. Wherein the limiting angle of the traffic data characteristic comprises one or a combination of more of the following:
Prohibiting exceeding a preset data packet size threshold;
Inhibit exceeding the cumulative data size threshold;
prohibiting exceeding a preset flow threshold;
inhibit having consecutive data packets;
Example 12: selection rules (10) or (11)
Reference may be made to rules (8) or (9);
Example 13: selection rule (12)
The method comprises the steps that a CP scheme is forbidden to initiate a service exceeding a preset data packet size threshold, a service exceeding an accumulated data volume threshold, a service exceeding a preset flow threshold or a service with continuous data packets, wherein the threshold can be notified to UE by a network side or preset by a transceiver;
The rule combines the limitation of the service data feature with the limitation of the access method, and the usage can refer to the previous rule with the limitation of the CP scheme and the limitation of the service data feature.
Example 14: selection rule (13)
Prohibiting the use of the UP scheme to initiate a service below a preset packet size threshold, or a service below a cumulative data volume threshold, or a service below a preset traffic threshold (meaning prohibiting the use of the UP mode to send small data/small traffic because the UP scheme is suitable for transmitting large data/large traffic)
The rule also combines the limitation of the service data feature with the limitation of the access method, except that the limitation of the access method is directed to the UP mode, so that the limitation of the corresponding service data feature and the rule (13) are different, and this example emphasizes that the UP mode cannot be used to transmit small data packets or low traffic.
When the eNB sends the rules, one or a plurality of rules can be selected, and the rules are selected without mutual conflict or mutual repetition.
Example 3:
this example serves to illustrate a more flexible manner of access restriction that may be formed in conjunction with additional restriction parameters.
Based on the access restriction rule of example 2, the eNB may additionally send other restriction parameters to cooperate with the access restriction rule to form a new and more flexible access restriction rule.
The additional limiting parameters include:
Time parameters, scale parameters, data model parameters:
-time parameter: adding corresponding WAIT TIMER to specify the time length for which the access restriction rule is effective;
-ratio parameters: increasing a probability factor or a scaling factor to define a probability or a UE scale at which the access restriction rule is valid;
-data model threshold: increasing a data packet size threshold, or an accumulated data volume threshold, or a traffic threshold, or a number of consecutive data packets, or a frequency/period threshold of consecutive data packets, to specify that a service contained in the access restriction rule is prohibited from exceeding the data model threshold, or is prohibited from being lower than the data model threshold;
the 3 parameters may be 1 parameter or a combination of parameters, and may be combined with the above-mentioned access restriction rule to form a new rule.
The specific values of the 3 parameters may be configured by the eNB and notified to the UE by a broadcast message or paging, or dedicated signaling.
Example 1: combining rule (2) "prohibit the call originating mo-ExceptionData, or delayTolerantAccess, or mo-signaling using CP mode" with the time parameter, a new rule can be formed as follows:
And prohibiting the call of mo-ExceptionData, delayTolerantAccess or mo-signaling from being initiated by using the CP mode in the set time range A.
The time range a may be configured by the eNB and notified to the UE by a broadcast message or dedicated signaling.
Example 2: combining rule (2) "prohibit the call originating mo-ExceptionData, or delayTolerantAccess, or mo-signaling using CP mode" with the ratio parameter, a new rule can be formed as follows:
the user number of the preset proportion B is forbidden to initiate the call of mo-ExceptionData, delayTolerantAccess or mo-signaling by using a CP mode.
The preset proportion B may be configured by the eNB and notified to the UE by a broadcast message or dedicated signaling. The eNB can prohibit the number of users of the proportion B from initiating a call of a restricted service type using the CP manner in this way.
Example 3: combining rule (2) "prohibit the call of mo-ExceptionData, delayTolerantAccess, or mo-signaling by CP mode" with the data model threshold, where the data model threshold further includes a data packet size threshold, or an accumulated data volume threshold, or a traffic threshold, or a number of consecutive data packets, or a frequency/period threshold of consecutive data packets, one or more of which may be selected. New rules may be formed as follows:
Prohibiting the CP mode from being used for initiating delayTolerantAccess calls exceeding the data packet size threshold;
disabling the CP mode to initiate a call of mo-signaling exceeding the cumulative data amount threshold;
Prohibiting the call of mo-ExceptionData exceeding the traffic threshold from being initiated by using the CP mode;
Disabling the CP mode to initiate a call of mo-ExceptionData, or delayTolerantAccess, or mo-signaling exceeding the frequency/period threshold of the consecutive packets;
disabling the CP mode to initiate the mo-ExceptionData call exceeding the traffic threshold or exceeding the quantity threshold of the continuous data packets;
example 4: the rule 'forbidden to send non-IP-data service' is combined with the time parameter, the proportion parameter and the data model threshold simultaneously to form a new rule as follows:
in a preset time range A, prohibiting the number of users of a preset proportion B from sending non-IP-data service exceeding a flow threshold;
Example 4:
