Set forth a lot of detail in the following description so that fully understand the present invention; but; the present invention can also adopt other to be different from other modes described here and implement, and therefore, protection scope of the present invention is not by the restriction of following public specific embodiment.

As shown in Figure 1, isomery UNE resource allocation methods according to an embodiment of the invention, comprise: S1, judge in the targeted environment that visible ray network and LTE network cover simultaneously, whether visible ray network is in upstate, if available, then the user in targeted environment is accessed visible ray network, and enter step S2, if unavailable, then the user in targeted environment is accessed LTE network, and enter step S3; S2 is the frequency resource that user distributes visible ray network by extremum method, is the power resource that user distributes visible ray network according to the attribute information of visible ray network channel; S3 is the frequency resource that user distributes LTE network according to the bandwidth demand of user, is the power resource that user distributes LTE network by improving water flood.

The improvement that the thought that the present invention is based on joint radio resource management (JRRM) is carried out.Advantage is the average resource that can be improved heterogeneous network system by load-balancing mechanism, by unified management, considers, and is the most suitable radio bearer of variety classes service selection, and then strengthens the Service Quality Management ability of network.In heterogeneous wireless network convergence system, no matter be for real time business or for non-real-time service, this programme can significantly improve system resource utilization efficiency.

According to technical scheme of the present invention, visible ray heterogeneous wireless network whole volume can be improved on the one hand, when equal number MPS process, adopt resource management mode of the present invention, under the prerequisite not increasing Internet resources, the service available number of users of visible ray heterogeneous wireless network significantly increases.Visible ray heterogeneous-network service quality can be improved on the other hand, for real time business, in Call-Control1 and handoff procedure, by carrying out load balancing to the selection of multiple access network, heterogeneous wireless network system can reduce service blocking rate and cutting off rate significantly; For non-real-time service, select to shunt by network, the effect reducing service delay, improve the average throughput of system can be reached.

Concrete Sample Scenario is as follows:

Targeted environment is visible ray and LTE isomery UNE, is 5 × 9m in floor space ²three layers of office building in, all regions are covered by a network (visible ray) and b network (LTE) simultaneously, and the set of heterogeneous network access point is M={1,2,3,4 ... M}, user's set is N={1,2,3,4 ... N}.Wherein LTE network has an access point, and VLAN has three access points, and each access point enjoys the bandwidth resources of 10MHz.LTE network has 3MHz bandwidth, and vlan network has 30MHz bandwidth.LTE network is ofdm system, and VLAN is ofdm system.The set of sub-channels of LTE network is combined into L={1,2,3......L}, and each subchannel bandwidth is B0.Each user can only select a network.

Wherein, represent that user i selects a network, then represent that user i selects b network, in order to avoid causing the cochannel in community to disturb, each frequency resource block at most only distributes to a user.

In the lte networks, every sub-channels can only distribute to user, i.e. a s _i,l=1 represents that user i selects l channel in b net, s _i,l∈ { 0,1}. represent that user i selects the transmitted power in b net on l channel, represent the bandwidth of user i in a net, represent the channel gain of user i in b net on down channel l. represent the transmitting power of user i down link in network a, represent the channel gain of user i in a net on down channel. for a network downstream channel noise power spectrum density, N ₀for b network downstream channel noise power spectrum density.

So, the transmission rate of user i in a network

$C_i^a=B_i^a{\log }_2(1+\frac{p_i^a\·g_i^a}{{\∂}_0\·B_i^a});$

The transmission rate of user i in b net

$C_i^b=\underset{l=1}{\overset{L}{\mathrm{\Σ}}}{s}_{i,j}{B}_0{\log }_2(1+\frac{p_i^l\·g_i^l}{N_0\·B_0});$

So the total throughput of the system that can draw is

$C=\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{\δ}}_i^a\·C_i^a+{\mathrm{\δ}}_i^b\·C_i^b;$

Take throughput of system as target function, the Mathematical Modeling of optimization problem is as follows

$\underset{{\mathrm{\δ}}_i^a,{\mathrm{\δ}}_i^b,s_{i,j},p_i^l,B_i^a}{\max }C=\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{\δ}}_i^a\·C_i^a+{\mathrm{\δ}}_i^b\·C_i^b$

Constraints is as follows:

$s.t.{\mathrm{\δ}}_i^a+{\mathrm{\δ}}_i^b=1\∀i\∈N;$

$\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{\δ}}_i^b\·s_{i,l}=1\∀l\∈L;$

$\underset{i=1}{\overset{N}{\mathrm{\Σ}}}\underset{l=1}{\overset{L}{\mathrm{\Σ}}}{\mathrm{\δ}}_i^b\·s_{i,l}\·p_i^l\≤P_{b\max };$

$p_i^l\≥0,\∀i,\∀l;$

$\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{\δ}}_i^a\·B_i^a\≤B_a;$

$B_i^a\≥0,\∀i=\mathrm{1,2,3}......N;$

Wherein, B _arepresent the total bandwidth restriction of network a, P _bmaxrepresent the gross power restriction of network b within the scope of office.

Because visible ray has the advantages such as message transmission rate is fast, bandwidth resources abundant, harmless than LTE, therefore, is user priority distribution visible ray Internet resources in office.Under visible ray Internet resources applicable, make three access points of user's priority access visible ray network.Suppose the power pi uniform distribution in visible ray network.In LTE, carrier power adjustable.

Therefore, the problems referred to above can be analyzed to two subproblems.One is parallel compensate maximize throughput, and corresponding target function is:

$\underset{{\mathrm{\δ}}_i^a{,}_{}{B}_i^a}{\max }\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{\δ}}_i^a{C}_i^a=\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{\δ}}_i^a{\log }_2(1+\frac{p_i^a\·g_i^a}{{\∂}_0\·B_i^a})$

Constraints is:

$s.t.{\mathrm{\δ}}_i^a\∈\left\{\mathrm{0,1}\right\};$

$\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{\δ}}_i^a\·B_i^a\≤B_a;$

$B_i^a\≥0,\∀i=\mathrm{1,2,3}......N;$

A network is visible ray, then for the direct path loss of visible ray, can be drawn by following formula.

Wherein, m is the radiation mode of light source, and A is photoelectric detector area, and d is the distance between transmitting terminal and receiving terminal be incidence angle, φ is the angle of departure, be optical filter gain, g (φ) is the gain of light amplitude transformer, φ _cbe receiver visual angle, i.e. FOV, when incidence angle is less than FOV, receiver can receive LED power, otherwise receiver cannot receive luminous energy.m＝1,T _s(φ)＝1,g(φ)＝1,A＝1cm ²。

Two is power division maximization total throughout target functions is:

$\underset{{\mathrm{\δ}}_i^b,p_i^b,s_{i,1,}}{\max }\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{\δ}}_i^b{C}_i^b=\underset{i=1}{\overset{N}{\mathrm{\Σ}}}\underset{l=1}{\overset{L}{\mathrm{\Σ}}}1{\mathrm{\δ}}_i^b{s}_{i,1}{\log }_2(1+\frac{p_i^1\·g_i^l}{N_0\·B_0})$

Constraints is:

$s.t.{\mathrm{\δ}}_i^a\∈\left\{\mathrm{0,1}\right\},s_{i,l}\∈\left\{\mathrm{0,1}\right\};$

$\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{\δ}}_i^b\·s_{i,l}=1,\∀i\∈N,\∀l\∈L;$

$p_i^l\≥0,\∀i,\∀l;$

$\underset{i=1}{\overset{N}{\mathrm{\Σ}}}\underset{l=1}{\overset{L}{\mathrm{\Σ}}}{\mathrm{\δ}}_i^b\·s_{i,l}\·p_i^l\≤P_{b\max };$
