Description

Method and device for network congestion alert and access control

technical field

The invention relates to the communication field, in particular to a network congestion alert and access control method and device.

Background technique

When the number of packet data transmitted in the packet domain mobile network is too large, the user's demand for network resources (including link bandwidth, storage space, and processor processing power, etc.) will exceed the inherent capacity, due to the limitation of network resources. The phenomenon of network transmission performance degradation, that is, network congestion occurs. Network congestion is a continuous overloaded network state. When the network is congested, data loss generally occurs, delay increases, and throughput decreases. Due to the lack of real-time fine-grained network congestion The control and reminder mechanism seriously affects the service quality of data services and user perception, and continuous network connections also cause user dissatisfaction and complaints.

Currently, the existing control methods for network congestion are:

1. Control from the perspective of the network side: it is also a common method, such as adopting at the transport layer: retransmission strategy, out-of-order caching strategy, confirmation strategy, flow control strategy and determining timeout strategy; at the network layer: using virtual circuits inside the subnet Datagram strategy, packet queuing and service strategy, packet discard strategy, routing algorithm and packet survival management; in the data link layer: retransmission strategy, out-of-order buffer strategy, confirmation strategy and flow control strategy;

2. Control from the perspective of the user side:

Judging whether the number of access users of the carrier carrying the data service reaches the threshold value of the number of users, making a network congestion judgment according to the judgment result, guiding network expansion, and improving the accuracy of judging the network congestion of the data service;

3. The network side and the user side cooperate to control:

The network side notifies the user equipment of the network congestion message carried in the network message, and the user equipment determines whether to initiate access according to the network congestion message.

By analyzing the existing congestion control methods for packet domain mobile networks, it has the following shortcomings:

1. The existing network congestion control mechanism is not combined with data service characteristics and user behavior:

Different from the voice service, the data service is not only carried on the packet domain mobile network through network resource sharing, but also has the characteristics of real-time, personalization and socialization. The existing network congestion control methods are all from the perspective of network management (such as Improve the utilization of network resources), access control (such as controlling the number of access users) to reduce the risk of network congestion, which is not combined with the occupation requirements of various data services for network resources, which has limitations. For example, the QQ service needs to maintain a long connection between the mobile terminal and the application server to maintain the heartbeat after the user logs in, while the web browsing service does not need to continuously occupy network resources, and is more of a one-time behavior.

In addition, on the mobile network, user groups of different types of terminals have different requirements for network resource occupation when using data services. For example, the iphone smart terminal user group and the ordinary smart terminal user group have different user behaviors for data services and have different requirements for network resource occupation.

It can be seen that the existing solutions lack real-time and fine-grained network congestion control according to the usage and occupancy requirements of different types of data services by user groups of different terminal types.

2. Lack of real-time network congestion reminder mechanism:

When network congestion occurs or the occupancy rate of network resources reaches the preset threshold, there is no real-time user reminder mechanism for the behavior habits and network resource occupation requirements of different terminal types of user groups. Frequent network connections of users consume traffic instead of Get good data business services and affect user perception.

In an application example, a real-time network congestion control and reminder method is proposed:

1. Through DPI technology, packet data flowing through GGSN can be parsed to obtain user number, terminal type, location, service information, traffic usage information, etc., as shown in the following table:

The meanings of the fields in the above table are as follows:

User number: such as 186XXXXXXXX;

Location information: LAC ID is the location area code, and CELL ID is the cell code. The location information can be obtained through the location area code. For example, 0111 is Beijing, and the location information of a specific cell can be obtained through the cell code. For example, 1234 is Financial Street;

Terminal types include: such as Iphone4S, Samsung N7102, Xiaomi 2A, etc.;

Business types include: such as web browsing, QQ, WeChat, email, etc.

Traffic usage information includes: usage time (unit is second), usage traffic (unit is Byte byte), average bandwidth (unit is bit per second, bps).

2. Calculating network resource occupation requirements

1. According to the location area code and cell code, each cell maintains a network resource occupation information table with different terminal types corresponding to different service types. As shown in Table 1, the network resource occupation information table records that different terminal types correspond to different services The average network resource usage of the type is as follows:

Table 1: Network resource occupation information table

In Table 1, the average duration That is, it is an average value of time spent by all mobile terminal users with the same terminal type and/or service type in the cell after using the data service for PDP deactivation. i is a positive integer, representing the number of mobile terminals with the same type of terminal and/or service type in the cell, and t _i represents the duration that mobile terminals of a certain terminal type use services of the corresponding service type. For example, there are 5 mobile terminals in the current cell whose terminal type is also used by Iphone4S and whose service type is QQ, and the average duration of use is 60s, 100s, 20s, 20s, and 200s respectively. Then, the terminal type is the service type used by Iphone4S The average time T1 used by the QQ mobile terminal is 80s.

Similarly, the average flow That is, in the cell, all mobile terminal users with the same terminal type and service type use the average value of the traffic after using the data service for PDP deactivation. j is a positive integer, indicating that the cell has the same terminal type and/or or the number of mobile terminals of a service type, and q _j represents the traffic of a mobile terminal of a certain terminal type using a service of a corresponding service type. average bandwidth It is the average value of the average bandwidth used by all mobile terminal users of specific similar terminal types and service types in the cell after using the data service for PDP deactivation. k is a positive integer, indicating that there are similar terminal types and service types in the cell. /or the number of mobile terminals of a service type, w _k represents the traffic of a mobile terminal of a certain terminal type using a service of a corresponding service type.

In addition, preferably, when the mobile terminal in the cell performs PDP deactivation, the corresponding terminal in Table 1 is updated according to the service conditions used by the mobile terminal (including the use time t of the data service, the used traffic q, and the average bandwidth w). The average duration T, average traffic Q, and average bandwidth W of the type and service type are calculated as follows:

T=AVG(t, T), that is, update T corresponding to the same terminal type and/or service type in the table to the average value of T and t.

Q=AVG(q, Q), that is, update the Q corresponding to the same terminal type and/or service type in the table to the average value of Q and q.

W=AVG(w, W), that is, update W corresponding to the same terminal type and/or service type in the table to the average value of W and w.

If there is no data corresponding to the same terminal type and service type in the table, add a new record information, T=t, Q=q, W=w.

For different cells, even for the same terminal type and/or service type, the average duration, average traffic, and average bandwidth are not the same, because users in different locations have different usage behaviors. Different types of terminals maintained in each cell correspond to network resource occupation information of different service types, depending on the specific usage of users in the cell.

In addition, the average duration, average traffic and average bandwidth occupied by each terminal type and/or service type in the cell are calculated and updated as the estimated value of mobile terminals with the same terminal type and/or service type when new access ; If there is a new mobile terminal to access the cell, these estimated values can be used to predict whether network congestion will occur in the current cell after accessing the mobile terminal.

2. Calculate the network resource occupation requirements of mobile terminals in the cell

Each cell needs to maintain a network resource occupation requirement table for each mobile terminal accessing the cell. As shown in Table 2, for all mobile terminal users in the cell that have undergone PDP activation and have not yet undergone PDP deactivation, the record has been activated The actual occupancy requirements of mobile terminals for network resources. At the same time, when a mobile terminal performs PDP activation, it is necessary to update the network resource occupation demand table of the cell, and record the estimated value of the mobile terminal being activated as the corresponding average network resource occupation in Table 1, as follows:

Table 2: Network resource occupation requirement table

In Table 2, serial numbers 1, 2, 4, and n represent mobile terminals that are undergoing PDP activation, and serial numbers 3 and 5 represent mobile terminals that have undergone PDP activation and have not yet undergone PDP deactivation. Duration, traffic and bandwidth. For a mobile terminal that is being activated by PDP, its duration occupancy requirements, traffic occupancy requirements, and bandwidth occupancy requirements are the average duration T, average duration Q, and average duration W corresponding to the same terminal type and/or service type in Table 1, that is, the preset valuation.

When the mobile terminal performs PDP activation, through this table, the number of mobile terminal users M carried in the cell, the list of numbers corresponding to different terminal types and/or service types, as well as the cell duration occupancy requirements T _N and cell traffic occupancy requirements can be obtained Q _N , the cell bandwidth occupation requirement W _N .

When the mobile terminal performs PDP activation, the table can be used to obtain the number A of users with the same terminal type and/or service type as the mobile terminal in the cell, and the duration occupancy requirements t _a , q _a and w _a .

The number of users A with the same terminal type and service type with the mobile terminal is the total number of rows with the same terminal type and/or service type with the mobile terminal in Table 2, and then the user number is removed; the duration occupancy requirement That is, in Table 2, the sum of the duration occupancy requirements of similar terminal types and/or service types; traffic occupancy requirements That is, in Table 2, the sum of traffic occupancy requirements of similar terminal types and/or service types; bandwidth occupancy requirements That is, in Table 2, the sum of the bandwidth occupation requirements of the same terminal type and/or service type; wherein, A is the number corresponding to the same type of terminal type and service type and A∈N. That is to say, the duration occupancy requirements t _a , q _a and w _a of the same terminal type and/or service type as the mobile terminal all include the duration occupied by all activated mobile terminals and active mobile terminals in Table 2 , traffic and bandwidth.

At the same time, when the mobile terminal completes the service use and performs PDP deactivation, calculate the network resource occupation requirements of the cell, including the number of users N carried in the cell, the cell duration occupation requirement T _N , the cell traffic occupation requirement Q _N , and the cell bandwidth occupation requirement W _N , and the number of users A corresponding to the same type of terminal and/or service type, the time duration occupancy requirement t _a , the traffic occupancy requirement q _a , and the bandwidth occupancy requirement w _a , and at the same time, update the network resource occupancy requirement table.
