Description
Technical Field
The invention relates to the technical field of communication, in particular to a queuing-based network access method which can be used for reducing the times of invalid user access applications during intensive access under high network load, protecting a network and improving the user satisfaction.
Background
The network is easy to be paralyzed in the service peak, mainly because a large number of users need to access the network, and the network has an access control mechanism, when the number of the accessed users reaches a certain number, the access control mechanism of the network is started, and the users applying for access subsequently can be refused to access the network; however, when the user is denied access, the user often tries to apply for access again, and repeatedly operates for a plurality of times to obtain an earlier opportunity to access the network, and the successful access of the user to the network has great randomness; when the users refused to access the network try to access repeatedly, a large amount of messages for applying for accessing the network appear on the target network, and therefore bandwidth resources are occupied.
In patent application No. 201610687036.0 entitled "a network access method and apparatus", a method is proposed that includes obtaining access selection parameters, calculating access membership of each access network according to the selection parameters, and selecting an access network according to the access membership. Another method for performing access control based on a backoff policy is to set a backoff time for a user equipment requesting access, and it is expected to alleviate a collision by the backoff policy and further to promote the resolution of the collision, the policy based on access Class barring (acb) is that an access network broadcasts an access probability and AC barring time for the user equipments within access Class AC (access Class) 0-9, and then each user equipment decides whether to initiate a random access process immediately by its randomly generated probability, if the probability value generated by each user equipment is less than the probability value broadcasted by the access network, then the random access is initiated, otherwise, the access behavior for a period of time is automatically barred, the policy is more suitable for processing the user equipments in the conventional cellular network, and most of the current research on network access control is concentrated in the wireless access field, the method is still highly random, does not meet fair access criteria, and is not transparent to the operator of the access device, who cannot determine when he can access the network.
When the information of the user applying for accessing the target network and the target network cannot be interacted in time, the user applying for accessing the target network can not determine when the user can access the network, subjectively, the more times of applying for accessing is, the larger the success rate of accessing is, so that the situation that the user which can not successfully access the network repeatedly sends an access request occurs, the increase of the times of invalid access application causes the waste of broadband resources, network operation faults are caused, and the satisfaction degree of the user is reduced.

Detailed Description
The method of the present invention is further described in detail and in full with reference to the accompanying drawings, in which:
referring to fig. 1, the network access method based on queuing according to the present invention includes the following steps:
step 1) setting network parameters:
setting various parameters of the target network, including: a) the system defaultQueueNumber is a number which is carried by a user applying for accessing to a network for the first time and is a fixed identifier which is the same for all users and is only used for distinguishing the user applying for the first time; b) the number of users granted at one time is preferably greater than or equal to 2, and because the authorized users have the possibility of giving up network access, the access rate can be better ensured by multiple users granted at one time; c) a controlledthreshold is set as the number of service users when the network can provide the best service state, that is, when the number of users of the network service is slightly larger than the threshold of the number of user accesses, the network can still normally operate in the state just exceeding the limit number, but the service quality is reduced; d) the queuing information updating period queueUpdatePeriod is determined according to the frequency of increase and decrease changes of queuing users on the target network, if the increase and decrease changes of the users on the target network are faster, the updating period is set to be shorter, and if the increase and decrease changes of the users on the target network are slower, the updating period is set to be longer, so that the requirement that the users know the dynamic state of the network queuing information in time is met; e) the access time window time length grantedAccessDuration is a time limit for obtaining the permission of the authorized user to access the network, and is used for reminding the authorized user to initiate a network access request in the time range and accessing the network as soon as possible; all the above items can be set by the network administrator according to the actual conditions of the respective networks.
Step 2) the user sends the request information of the access target network:
a user needing to access a target network sends access request information to the target network through the existing wireless network or wired network, wherein the access request information comprises an identification number (ID) of the user and a queuing number defaulted by a system; the user ID may be an internet protocol address IP, a hardware address MAC or other address for identifying the user, or a combination of several addresses.
Step 3), the target network counts the number of users of the current service:
the target network needs to count the number of users in service at any time, when a new user accesses, the number of corresponding new access users is increased, and when a user exits, the number of corresponding exiting users is reduced; after the target network is started, the number of the service users of the target network is set to be 0, the number of the service users of the target network is increased by 1 when one user is successfully accessed in the working process, the number of the service users of the target network is decreased by 1 when one user exits the network, and by analogy, the target network counts the number of the current service users in real time, so that the numerical value of the number of the target network service users is equal to the number of the current service users of the target network.
Step 4) judging whether the number of the users currently served is larger than or equal to the threshold of the access control user:
when processing an access request of an access user, the target network firstly judges the number of users of the current service to determine whether the number of users is greater than or equal to a preset access control user threshold, and if the number of users of the current service is greater than or equal to the access control user threshold, the access control mechanism is started, so that the subsequent users are prevented from entering the network, and the purpose of limiting the number of users of the current service is achieved. In the network access control state, executing the step (4.1); otherwise, the access control mechanism is not started, the user normally accesses the network, and the step (4.2) is executed;
step (4.1) suspending access:
when the number of the accessed users is larger than or equal to the preset access control user threshold on the target network, the target network temporarily blocks the subsequent newly applied network access users who want to enter the network due to the opening of the access control mechanism, the network access time of the part of users is delayed, and the users in the queue are sequentially authorized to access the network according to the first-come-first-serve principle after being queued according to the time sequence; the target network allocates queuing numbers for users who newly apply for network access, and sends queuing information to the equipment requesting for network access, the queuing information is periodically updated and periodically sent, the users requesting for network access determine the time waiting for access according to the queuing information on the equipment, the users apply for network access again when obtaining authorization, the target network receives the network access request of the authorized user and grants the authorized user to access the network, and the occurrence of network paralysis and other faults is avoided by the mode of suspending access.
Step (4.1a), the target network queues the users which can not access the network temporarily:
when the target network is busy, under the action of the access control mechanism, the target network does not temporarily accept new user access; at this moment, the network queues the part of users which can not access the network temporarily according to the rule of first-come first-serve and gives out a queuing number, and simultaneously sends access response information, wherein the information carries the corresponding queuing number of the user and the maximum queuing number of the current service user of the target network, after the user applying for accessing the target network receives the access response information, a network access information indication popup window is generated on the equipment of the user, as shown in figure 2, wherein the network access information indication popup window comprises the queuing number, the maximum queuing number of the current service user and the network access information indication popup window with waiting time, and the waiting time information is determined by the difference between the local time of receiving the access response information and the real-time local time;
step (4.1b) the target network sends the maximum queuing number of the current service user:
the target network sends the maximum queuing number information of the current service user to the user to be accessed in the queue according to the queuing information updating period, so that the user to be accessed can update the information in the network access information indication popup window immediately; after receiving the information, the user waiting for access in line performs subtraction operation by using the queuing number and the maximum queuing number of the current service user of the target network to know how many users in front of the user wait for access, further estimates the waiting time needed for accessing the target network, and decides to continue waiting or quit waiting, if the user wants to quit waiting, the user clicks a small fork at the upper right corner of the figure 2 to close a popup window, so that the queuing opportunity can be abandoned, after the network access information indicates that the popup window is closed, the user can send a queuing abandoning instruction to the target network, and the target network removes the user from the queue list after receiving the instruction.
Step (4.1c) the target network authorizes the user to access the network:
after the number of the target network service users is reduced, the target network authorizes a plurality of users waiting for access to access the network and sends an access time window to each authorized user, in order to ensure that after the target network sends authorization information, the users waiting for access are ensured to send access requests by a large probability event, and the number of the users authorized for access at one time by the target network is more than 2; after a user waiting for access in a queue receives authorization information sent by a target network, network access information on equipment indicates that a popup window is changed into an authorized access popup window, as shown in fig. 3, the popup window adopts a countdown structure to display time allowed to access the target network, and reminds the user to access the network within the time range, meanwhile, the window comprises an access button and a abandon button for the user to select, at the moment, the authorized user can select to click the access button to apply for accessing the target network, and can also click the abandon button to abandon the authorization obtained at this time, so that the user exits the queue.
Step (4.1d) authorized user sends network access request:
the authorized user initiates a network access request through an authorized access popup within a specified time range, wherein the network access request information carries a queuing number of the user;
step (4.1e) authorized user accessing network
In the time range allowing the target network to be accessed, the target network receives the network access request of the authorized user, permits the user to access the network and updates the maximum queuing number of the current service user of the target network; and when all the users authorized at this time have access to the network or the time allowed to access the target network is over, executing the step (4.1 b).
Step (4.2) normal access:
when the number of the accessed users is smaller than the preset access control user threshold on the target network, the access control mechanism is not started, and the target network receives the request of the users for accessing the network, processes the request information and allows the users to access the network; at the moment, the user applying for network access can normally access the network to obtain the service without queuing and waiting.
Referring to fig. 2, a popup is indicated for a network access message generated on a device of a user during queuing waiting in the present invention, where the popup includes a queuing number allocated to the queued user, a maximum queuing number of a current service user of a target network, and a user waiting time; the waiting time information is obtained by subtracting the real-time local time from the local time when the user equipment receives the access response information, and is displayed to the user; the information window is convenient for a user to know access information and network service information of a target network in real time, the user is prevented from blindly sending an access application due to an unknown condition, unnecessary waste of network resources is caused by repeated access attempts, and the repeated access attempts have high randomness, the success rate of network access is low, and the satisfaction degree of the user is influenced.
Referring to fig. 3, the invention is an authorized access popup displayed on a device of a user waiting for access in line after receiving authorization information sent by a target network, wherein the popup represents that the user enters an authorized access state from a waiting in line state; at the moment, the network access information displayed to the user indicates that the popup is replaced by the authorized access popup in a queuing state, a countdown structure is adopted in the authorized access popup to display the time for allowing the access to the target network, the user is reminded of accessing the network in the time range, meanwhile, the window comprises an access button and a abandon button for the user to select, the access button is clicked to indicate that the authorized user applies for accessing the target network, and the abandon button is clicked to indicate that the authorized user abandons the access opportunity and quits the queue; on the premise of embodying fair access, the information window adopts a countdown mode to ensure access efficiency, so that a user can conveniently determine an access time point, the times of sending an access request by the user are reduced, and the probability of successful access of the user to a target network is improved.
The foregoing description is only an example of the present invention and is not intended to limit the invention, so that it will be apparent to those skilled in the art that various changes and modifications in form and detail may be made therein without departing from the spirit and scope of the invention.
