A kind of load balancing adaptive approach based on user equipment has been supplied, to achieve the purpose that load balancing, has improved network ginseng
Number configuration adaptivity and user experience.The technical solution mainly includes following processing: using cell global unique identification (or
Cell Global Identification) (Cell Global Identity, referred to as CGI) can be with one radio access node of unique identification and section
Cell information in point.For Universal Terrestrial wireless access network (the Evolved Universal Terrestrial of evolution
Radio Access Network, referred to as EUTRAN) and land radio access web (Terrestrial Radio Access
Network, referred to as UMTS) wireless communication system, CGI content includes network identity (for example, public-land mobile network
(Public Land Mobile Network, referred to as PLMN) mark and cell ID (Cell Identity), for GSM
EDGE Radio Access Network (Radio Access Network, referred to as RAN) wireless communication system, CGI also increase position area
Domain code (Location Area Code) mark.
The load balancing adaptive approach includes: when mobile device and radio access node establish radio resource, from this
CGI information is read out in Cell Broadcast Channel, when mobile device release radio resource returns to idle state, record last time is it
The cell ID CGI of service is provided.When large number of equipment is moved to new radio access node coverage area, needing to carry out business
When with radio access node establish connection when, air interface standard signaling radio resource establish request (RRC Connection
Setup Request) explicit the increases cell Last CGI of message is indicated to the radio access node being currently accessed, if set
In stipulated time T, it is desirable that the mobile device quantity N_user of access has reached preset numerical value of N _ t_user_max, and
It has been more than radio node definition that accessing after load capacity N_access is added with N_user, which has occurred, in current radio access node
Maximum allowable access numerical value of N _ max_allowed, then it is N_max_ that current radio node, which adjusts maximum allowable access number,
Allowed+N_user, while receiving new user equipment is its distributing radio resource, and according to user equipment in RRC connection
The Last CGI information carried when establishing request message extracts the number of user equipment (N_same_ with identical CGI information
Cgi_1, N_same_cgi_2 ..., N_same_cgi_n), and N_same_cgi_1+N_same_cgi_2+ ...+N_same_
Cgi_n=N_user.Current eNodeB can be by X2 standard interface, according to CGI information respectively to different former wireless access
Node sends message (Load Number Adjust, N_same_cgi_i), here i=1,2 ..., n.Receive each of message
Former access node carries out maximum allowable access customer number purpose adjustment respectively, and former access node adjusts most according to N_same_cgi_i
It is big that accessing user's number is allowed to be M_max_allowed-N_same_cgi_i.Guarantee in this way for core net node, maintenance

It is dynamically adjusted when overloading phenomenon.
Figure 10 is the overview flow chart according to an embodiment of the present invention based on mobile device load-balancing method, such as Figure 10 institute
Show, which includes the following steps:
Step S1002, UE records current radio access node (for example, eNodeB) unique identification CGI, i.e., in mobile device
When establishing radio resource with radio access node and connect, the unique mark in the whole world for identifying the radio node is obtained from broadcast channel
Know CGI, and records CGI when Release radio resource is in idle condition；
Step S1004, UE carry CGI, example when sending radio resource foundation request (RRC Connection Request)
Such as, large number of equipment is moved to new radio node (maximum allowable accessing user's number N_max_allowed, accessed user's number
Mesh N_access) in coverage area when initiation business, the CGI information of record is filled in RRC Connection Setup
In Request message；
Step S1006 judges that current radio node requires whether the number of users N_user of access surpasses in stipulated time T
The number of users N_t_user_max for allowing to access has been crossed in the stipulated time, that is, has judged whether N_user is greater than N_t_ in T time
User_max enters step S1008, otherwise enters step S1014 in the case where the judgment result is yes；
Step S1008, the user data N_user of determination requirement access and the number of users N_access of existing access are total
Whether it has been more than maximum allowable accessing user's number N_max_allowed, that is, whether has judged the sum of N_user and N_access
It has been more than N_max_allowed, in the case where the judgment result is yes (i.e. current radio access node is in overload), into
Enter step S1010, otherwise enters step S1012；
Step S1010, it is N_max_allowed+N_ that current radio access node, which adjusts maximum allowable accessing user's number,
User, and the user equipment distributing radio resource to require access, while according to RRC Connection Setup
The CGI information carried in Request extracts the number of users N_same_cgi_ of the new demand access with identical CGI respectively
(i=1,2 ... n), N_same_cgi_i≤N_user, N_same_cgi_1+ ...+N_same_cgi_n=N_user by i；
Step S1012 notifies original eNodeB to carry out adjustment of load (Load Number Adjust) according to CGI；Current nothing
Increased permission accessing user's number (N_max_allowed+) of line access node allows to connect with former radio access node reduction
Access customer number (M_max_allowed-) is equal, and N_max_allowed+=M_max_allowed-=N_user, that is, works as
Preceding radio access node notifies corresponding former radio access node (Load according to CGI information by X2 interface respectively
Number Adjust), adjust maximum allowable accessing user's number max_allowed-N_same_ of former radio access node
Cgi_i guarantees the maximum allowable accessing user's number summation of each radio access node, does not exceed core net and accommodates user's maximum
Numerical value；
Step S1014, current radio access node (i.e. new eNodeB) establish connection for new access user equipment and provide clothes
Business.When current radio access node release mobile device, mobile device records the CGI information of current radio access node, and replaces
Change the CGI for having been provided to current radio access node.
By above step, radio access node can be according to the mobility of UE and dynamic adjusts the maximum allowable of node and connects
Enter number of loads, the adjustment of all node self-adaptings is to achieve the effect that load balancing, it should be noted that works as user equipment
When moving to other new radio access nodes, CGI information is supplied to new radio access node, when new radio access node overloads
When, readjust former radio access node and the maximum allowable accessing user's number of new radio access node.
Through the foregoing embodiment, it uses mobile device and records former radio access node identification information, be moved to new nothing
The covering of line access node, is supplied to new node for origin node CGI information in the business of progress, if overload occurs in new node
When, maximum access number of loads can be accurately adjusted, and origin node is reduced because mobile device is not in origin node coverage area
Maximum access number of loads, so that radio node load sum does not exceed core net maximum and accommodates number of users.The load is equal
Weighing apparatus mode will not interrupt the customer service accessed and will not influence the service access of new user.The node of whole network accesses
Number of users constantly changes with the migration of mobile device, and not will lead to the feelings of radio node overload after load balancing
Condition.Signaling between network element only occurs along with the migration of mobile device, and network signal is not in redundancy, has load equal
The advantages such as the purpose that weighs and accuracy are stronger.
