Reader schematically illustrates made by understanding, and does not constitute a limitation of the invention.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.
Firstly, the application scenarios for providing method for controlling network congestion provided in an embodiment of the present invention are as shown in Figure 1, wherein
Base station 10 passes through the RRC connection number in real-time monitoring cell 30, and when the RRC connection number for finding cell 30 is larger, right in time
Part terminal 20 in cell 30 configure, and to reach the RRC connection number reduced in cell 30, reduces the hair of network congestion
It is raw, alleviate the problem of next new user accesses obstruction.
Secondly, for ease of understanding, being briefly discussed below to carrier aggregation technology and related notion:
The polymerization of so-called carrier wave be scrappy frequency range is merged into one " virtual ", broader frequency range, with broader at this
Simultaneous transmission user data in frequency range, to reach the transmission bandwidth for increasing user data, the purpose of improve data transfer rate.
Wherein, the scrappy frequency range is referred to as member carrier (Component Carrier, CC).For convenient for at
Member's carrier wave is managed, and CC is divided for main member carrier (Primary Carrier Component, PCC) and SCC.?
In lte-a system, the polymerization of 1 PCC and at most 4 SCC are supported, by establishing terminal and base station simultaneously on PCC and SCC
Multiple RCC connections, can be realized the rapid data transmission of terminal and base station.
However, by supporting the terminal of carrier wave polymerization on the multiple member carriers activated while can establish multiple
RRC connection, therefore when the terminal for supporting carrier wave to polymerize in network is more, the RRC connection number in cell is often larger, and base station
The RRC connection that can be provided is limited, this allows for the practical terminal quantity that can access of whole net and substantially reduces, easy so as to cause network
Congestion occurs, seriously affects the communication quality of system, and influence the access of new user.
For this purpose, a kind of method for controlling network congestion of the embodiment of the present invention, as shown in Figure 2, comprising:
S201, base station obtain the ratio that the RRC connection number in cell accounts for its maximum number of connections.
Wherein, the maximum number of connections of cell depends on the capacity of equipment of its own base station, specifically can be according to the configuration of base station
It obtains, the present invention is not especially limit this.
Preferably, base station can carry out congestion control according to the ratio according to the acquisition of the preset cycle ratio.
Certainly, power consumption brought by the ratio is obtained to reduce, the ratio can also be obtained in the more specific time period of accessing user, into
Row congestion control, the present invention is not especially limit this.
Specifically, as shown in figure 3, can obtain the RRC connection number in cell by S201a-S201b as follows accounts for it
The ratio of maximum number of connections:
S201a, base station obtain the number of CA terminal and non-CA terminal in cell in connected state and are in connected state
The number of SCC that is activated of each CA terminal.
It should be noted that it will be understood by those skilled in the art that CA terminal described in the embodiment of the present invention refers to support
The terminal of carrier wave polymerization, correspondingly, the non-CA terminal refers to the terminal for not supporting carrier wave to polymerize.
The SCC that S201b, base station are activated according to CA terminal and non-CA terminal number and each CA terminal in connected state
Number determine that the RRC connection number in cell accounts for the ratio of its maximum number of connections in conjunction with preset formula.
Wherein, preset formula includes formula as follows (1) and formula (2):
P=Num_RRC_total/Num_RRC_max formula (2)
In formula, Num_RRC_total indicates the RRC connection number in cell, and Num_CA indicates to be in connected state in cell
The number of CA terminal, Num_CA_i_SCC_active indicate the number for the SCC that the i-th CA terminal in cell in connected state activates
Mesh, Num_non_CA indicate the number of the non-CA terminal in cell in connected state, and P indicates that the RRC connection number in cell accounts for it
The ratio of maximum number of connections, Num_RRC_max indicate the maximum number of connections of cell.
Illustratively, it is assumed that base station includes 23 cell 0, cell 1 and cell cells, and current area 1
In in the CA terminal of connected state have UE201, UE202 and UE2033 terminals, UE201, UE202 and UE203 are being carried out
Business be Non-GBR business, the SCC count mesh that UE201, UE202 and UE203 are activated is respectively 3,2,4, in cell 0
There is 1 terminal of UE204 in the non-CA terminal of connected state, then the RRC connection number Num_ of cell 1 can be calculated according to formula (1)
RRC_total is 3+3+2+4+1=13.Further, it is assumed that the maximum RRC connection number Num_RRC_max of cell 1 is 12, then
The ratio P=108% that RRC connection number in cell 1 accounts for maximum RRC connection number can be calculated according to formula (2).
If S202, base station determine that the RRC connection number in cell accounts for the ratio of the maximum number of connections of cell more than or equal to pre-
If threshold value, the m terminal most to the SCC count activated in the target terminal of cell configure, so that the RRC in cell connects
The ratio for connecing the maximum number of connections that number accounts for cell is less than preset threshold.
Wherein, the target terminal of cell is the CA terminal that Non-GBR business is carried out in cell, and m is positive integer, and m is less than
Equal to the sum of the target terminal of cell.
It is appreciated that if the ratio that the RRC connection number in cell accounts for cell maximum number of connections is greater than or equal to preset threshold,
Then illustrate that the RRC connection number in cell at this time is larger, easily cause network congestion, therefore, need to carry out configuring in time, to reduce
The generation of network congestion, the communication quality of optimization system.
It should be noted that according to the difference of service quality (Quality of Service, QoS), it can be by delineation of activities
For ensures bit rate (Guaranteed Bit Rate, GBR) business and Non-GBR business two major classes.Wherein, GBR traffic refers to
The distribution constant by network " permanent " of bit rate required by business, even if the corresponding bit speed in network over loading or congestion
Rate is also able to maintain, the impregnable a kind of business of quality of service, for example, the real time business such as voice service, video traffic are
Typical GBR traffic.And Non-GBR business refers to not requiring QoS, needs to bear in the case where network congestion to reduce bit
The business of the requirement of rate, as webpage (Web) application, Email (Electronic Mail, E-mail) setting etc. belong to
Non-GBR business.Since Non-GBR business does not need to occupy fixed Internet resources, can establish for a long time, therefore work as net
When congestion occurs for network, it can be carried out by the terminal more to the SCC count activated in the CA terminal for carrying out Non-GBR business in network
It goes to configure, to reduce the RRC connection number in cell in not traffic affecting, avoids network congestion, optimization system is led to
Believe quality.
Illustratively, an example is connected, it is assumed that preset threshold 92%, according to aforementioned calculating P=108%, 108% >
92%, therefore the ratio that RRC connection number accounts for maximum RRC connection number in cell 1 is greater than preset threshold, thus need to be in cell 1
Terminal execution in part goes to configure, so that the ratio that the RRC connection number in cell 1 accounts for the maximum number of connections of cell 1 is less than default threshold
Value.
Preferably, in step S202, base station carries out the least m terminal of the SCC count activated in the target terminal of cell
It goes to configure, so that the ratio that the RRC connection number in cell accounts for the maximum number of connections of cell is less than preset threshold, specifically can wrap
It includes:
The sequence of the number for the SCC that the base station S202 ' is activated according to m terminal from high in the end, successively goes m terminal
Configuration, until the ratio that the RRC connection number in cell accounts for the maximum number of connections of cell is less than preset threshold.
That is, terminals first most to the SCC count activated in m terminal configure, later, judge that deallocation postpones cell
Whether the ratio that middle RRC connection number accounts for the maximum number of connections of cell is less than preset threshold, if being less than, stops；If being not less than, after
The continuous terminal more to the SCC count activated in addition to removing configurating terminal in m terminal time configure, and judges that deallocation postpones
Whether the ratio that RRC connection number accounts for the maximum number of connections of cell in cell is less than preset threshold, if being less than, stops, if not small
In then continuing configure to next terminal ..., in this way, until the RRC connection number in cell accounts for the maximum connection of cell
Several ratio is less than preset threshold.
Specifically, configure to any terminal-first terminal in m terminal, can specifically include as follows
S202a-S202b:
S202a, base station determine corresponding first SCC of first terminal.
Wherein, corresponding first SCC of first terminal is the smallest SCC of resources occupation rate in the SCC of first terminal activation.
S202b, base station send RRC connection reconfiguration to first terminal and set message.
Wherein, RRC connection reconfiguration sets the mark that message carries the first SCC, and RRC connection reconfiguration sets message and is used to indicate
One terminal discharges its RRC connection established on the first SCC.
Illustratively, an example is connected, as shown in figure 5, carrying out the detailed process of configuration to the target terminal in cell 1
Are as follows:
S1: base station determines corresponding first SCC of the most terminal-UE203 of the SCC count activated in target terminal.
Assuming that 4 carrier waves of UE203 activation are carrier wave 0, carrier wave 1, carrier wave 2 and carrier wave 3, and the resource occupation of each carrier wave
Rate is followed successively by 30%, 10%, 20%, 40%, then can determine that wherein resources occupation rate is the smallest is carrier wave 1, it is thus determined that
Corresponding first SCC of UE203 is carrier wave 1.
S2: message is set to the RRC connection reconfiguration that UE203 sends the mark for carrying carrier wave 1 in base station.
S3:UE203 receives the RRC connection reconfiguration that base station is sent and sets message, and is set in message and taken according to the RRC connection reconfiguration
The mark of the carrier wave 1 of band discharges the RRC connection established on carrier 1.
S4: it is default that base station judges whether the ratio that RRC connection number accounts for 1 maximum RRC connection number of cell in current area 1 is less than
Threshold value.
Specifically, can determine that postponing RRC connection number in cell 1 to UE203 deallocation is 12 according to formula (1), and cell 1
Maximum RRC connection number be 12, therefore can determine in current area 1 that RRC connection number accounts for 1 maximum RRC of cell company according to formula (2)
Meeting several ratio P is 100%, is still greater than preset threshold 92%.
S5: the ratio that base station determines that RRC connection number accounts for 1 maximum RRC connection number of cell in cell 1 is not less than preset threshold,
Determine more corresponding first SCC of terminal-UE201 of the SCC count time activated in the target terminal of cell 1.
Assuming that 3 carrier waves of UE201 activation are carrier wave 4, carrier wave 5 and carrier wave 6, the resources occupation rate of each carrier wave is followed successively by
30%, 25%, 15%, then can determine that wherein resources occupation rate is the smallest is carrier wave 6, it is thus determined that UE201 corresponding first
SCC is carrier wave 6.
S6: message is set to the RRC connection reconfiguration that UE201 sends the mark for carrying carrier wave 6 in base station.
S7:UE201 receives the RRC connection reconfiguration that base station is sent and sets message, and is set in message and taken according to the RRC connection reconfiguration
The mark of the carrier wave 6 of band discharges the RRC connection established on carrier wave 6.
S8: it is default that base station judges whether the ratio that RRC connection number accounts for 1 maximum RRC connection number of cell in current area 1 is less than
Threshold value.
Specifically, can determine that RRC connection number is 11 in current area 1 according to formula (1), and the maximum RRC of cell 1 connects
Connecing number is 12, can determine that the ratio P for the maximum RRC connection number that RRC connection number accounts for cell 1 in current area 1 is according to formula (2)
91.6%, it is less than preset threshold 92%.
S9: base station determines that the ratio that RRC connection number accounts for 1 maximum RRC connection number of cell in current area 1 is less than default threshold
Value, end go to configure.
So far, base station completes web impact factor, and the RRC connection number in cell is accounted for its maximum RRC connection number
Ratio has been reduced to preset threshold or less, it is thus possible to effectively reduce the generation of network congestion, the communication quality of optimization system has
Conducive to the access of new user.

At least two second terminals successively configure by the sequence of the resources occupation rate of corresponding 2nd SCC from low to high.
Wherein, corresponding 2nd SCC of second terminal is the smallest SCC of resources occupation rate in the SCC of second terminal activation.
Illustratively, an example is connected, it is assumed that the SCC count mesh of UE201 and UE202 activation in cell 1 are 3, UE203
The SCC count mesh of activation is still 4, then base station postpones UE203 progress deallocation, determines the SCC that UE201 and UE202 is activated respectively
Middle the smallest 2nd SCC of resources occupation rate, according to the resources occupation rate sequence from small to large of the 2nd SCC to UE201 and UE202
Configure.Specifically, it is assumed that the resources occupation rate of carrier wave 6 in the SCC (carrier wave 4, carrier wave 5, carrier wave 6) of UE201 activation
Minimum, it is 10% that the resources occupation rate for carrier wave 7 in the SCC (carrier wave 7, carrier wave 8, carrier wave 9) of 15%, UE202 activation is minimum,
Then corresponding 2nd SCC of UE201 and UE202 is respectively carrier wave 6 and carrier wave 7, and is carried since the resources occupation rate of carrier wave 7 is less than
The resources occupation rate of wave 6, therefore base station is postponed to UE203 progress deallocation, first configure to UE202, be judged again later
Whether the ratio that RRC connection number accounts for maximum RRC connection number is less than preset threshold, if it is not, then continuing configure to UE201.
