Network selection shunted, can reach reduce service delay, improve system average throughput effect.
Concrete scene example is as follows:
Target environment is visible ray and LTE isomery UNEs, is 5 × 9m in floor space2Three layers of office building in, institute
There is region by a networks (visible ray) and b networks (LTE) while cover, heterogeneous network access point set is M={ 1,2,3,4 ...
M }, user's collection is combined into N={ 1,2,3,4 ... N }.Wherein LTE network has an access point, and VLAN has three access points, each
Access point enjoys 10MHz bandwidth resources.LTE network shares 3MHz bandwidth, and vlan network shares 30MHz bandwidth.LTE network
For ofdm system, VLAN is OFDM systems.The set of sub-channels of LTE network is combined into L={ 1,2,3......L }, per sub-channels
With a width of B0.Each user can only select a network.
Wherein,User i selection a networks are represented, User i selection b networks are then represented,In order to avoid causing the cochannel in cell to disturb, each frequency resource block is at most assigned to only a user.
In the lte networks, a user, i.e. s can only be distributed to per sub-channelsi,l=1 represents in user i selection b nets
L-th of channel, si,l∈{0,1}。The transmit power on l channels in user i selection b nets is represented,Represent user i in a nets
In bandwidth,Represent channel gains of the user i in b nets on down channel l.Represent user i descending chains in network a
The transmission power on road,Represent channel gains of the user i in a nets on down channel.For a network downstream interchannel noise work(
Rate spectrum density, N0For b network downstream channel noise power spectrum densities.
So, in a networks user i transmission rate
User i transmission rate in b nets
Then it can show that the total handling capacity of system is
Using throughput of system as object function, the mathematical modeling of optimization problem is as follows
Constraints is as follows:
Wherein, BaRepresent network a total bandwidth limitation, PbmaxRepresent general power limitations of the network b in the range of office.
Because visible ray mutually has the advantages that message transmission rate is fast, bandwidth resources are abundant, harmless than LTE,
Therefore, visible optical network resource is preferentially distributed for user in office.In the case of visible optical network resource is available, use
Three access points of the visible optical-fiber network of family priority access.Assuming that the power p in visible optical-fiber networkiEvenly distribute.In LTE, carry
Wave power can adjust.
Therefore, above mentioned problem can be analyzed to two subproblems.First, frequency distributes maximize handling capacity, corresponding target letter
Number is:
Constraints is:
A networks are visible ray, thenIt is lost, can be drawn by following formula for the direct path of visible ray.
Wherein, m is the radiation mode of light source, and A is photodetector receiving area, DdIt is between transmitting terminal and receiving terminal
DistanceIt is incidence angle, φ is the angle of departure,It is optical filter gain, g (φ) is light amplitude transformer gain, φcIt is receiver
Visual angle, i.e. FOV, when incidence angle is less than FOV, receiver can receive LED power, and otherwise receiver can not receive light
Energy.M=1, Ts(φ)=1, g (φ)=1, A=1cm2。
Second, power distribution maximization total throughout object function is:
Constraints is:
One of subproblem is first solved respectively, in the case of the determination of frequency (or bandwidth) resource, then solves another variable
Optimal solution.It is first user's dividing frequency resource, is then user's distribution power resource again.
By being that user selects access network according to user's request and network condition, and asked according to customer service as user point
It is user's distribution power resource with improvement water flood with frequency resource, each user can be allowed to have more preferable experience, improves and use
The fairness at family.And by considering the resource allocation conditions of visible optical-fiber network and LTE network, net can be merged in isomery
In the environment of network covering, more reasonably classify power resource and frequency resource for user.
To maximize overall system throughput as optimization aim, while meet system bandwidth constraint and general power limitation, it is right
System frequency and power resource carry out co-allocation.It is that user selects access network and optimum bandwidth with exhaustive search iterative method
And power resource, resource allocation is reduced to two sub- assignment problems:1) concavity of Utilizing question, it is that user distributes with extremum method
Frequency resource.2) consider user QoS (Quality of Service) demands and channel utilization, take into account the public affairs between user
It is flat, propose improved water injection power allocation algorithm.The present invention have studied resource management side of the visible ray heterogeneous network based on IP layers
Method, throughput of system can be improved, and improve the fairness of system.

S2 and/or step S3, frequency resource and power resource are redistributed for user;S5, repeat step S4, until target environment gulps down
The amount of telling no longer improves.
Whether by adjusting access network, it is optimal (i.e. whether handling capacity is not improving) to detect user access network, if
It is not to reselect access network for user, so as to which access network is adjusted into optimum state, to ensure to access network throughput
Most preferably.
Preferably, improving water flood includes:It is total according to the power resource of the number of users of access LTE network and LTE networks
With calculating power resource average, it is the power resource that user distributes LTE networks by water flood, is that distribution power resource is zero
User resource allocation power average, iteration is until the power resource of no user is zero.
It is not single only to be come with channel condition for user resource allocation by improving water flood, each user can be allowed to have point
Certain power resource is fitted on, improves the fairness of user.
Preferably, also include before step S1:S0, user's descending is arranged according to the bandwidth demand of user.
First user is ranked up before treatment, can be in order to controlling use according to bandwidth demand in subsequent processes
Family is accessed.
Preferably, step S1 also includes:When visible optical-fiber network can be used, bandwidth demand in target environment is more than preset value
User access visible optical-fiber network, other users are accessed into LTE networks.
