The utilization rate of air interface resource of this any community obtained in above process and the threshold value preset are compared, when above-mentioned utilization rate of air interface resource is greater than default threshold value, according to the channel quality parameter of at least one carrying to be accessed, obtain the Service Quality Metrics of at least one carrying to be accessed; Otherwise, be Service Quality Metrics weighted factor assignment, and obtain the Service Quality Metrics of at least one carrying to be accessed according to formula one.Wherein, above-mentioned default threshold value can pre-set according to concrete network application situation, and preferably, this threshold value preset is 70% ~ 90%.

In the embodiment of the present invention, according to the channel quality parameter of at least one carrying to be accessed, the process obtaining the Service Quality Metrics of at least one carrying to be accessed is: base station, according to the channel quality parameter of at least one carrying to be accessed above-mentioned, obtains the Service Quality Metrics weighted factor of this at least one carrying to be accessed; Obtain the rate requirement information of carrying in above-mentioned access request message, based on this rate requirement information, obtain the load factor increment of this at least one carrying to be accessed; Obtain the rate requirement information of access bearer corresponding to each accessed user's equipment corresponding to the above-mentioned any community of current time respectively, based on this, the rate requirement information of each access bearer, determines the total load rate of all access bearers; According to the Service Quality Metrics weighted factor of at least one carrying to be accessed, the load factor increment of at least one carrying to be accessed, and total load rate, obtain the Service Quality Metrics of at least one carrying to be accessed.

Further, the Service Quality Metrics of at least one carrying to be accessed adopts following formula to obtain:

Q=ρ+v _m' Δ ρ (formula two)

Wherein, Q is the Service Quality Metrics of at least one carrying to be accessed; ρ is the total load rate of all access bearers; Δ ρ is the load factor increment behind at least one carrying access community to be accessed, and its value is estimated value; v _m' be Service Quality Metrics weighted factor.

In above process, the process obtaining the Service Quality Metrics weighted factor of at least one carrying to be accessed is: base station adds up the channel quality parameter of each access bearer respectively, and according to this channel quality parameter of each access bearer, obtain the average channel quality parameter of all access bearers; According to the channel quality parameter of at least one carrying to be accessed above-mentioned, the average channel quality parameter of access bearer, obtains the Service Quality Metrics weighted factor of at least one carrying to be accessed.Wherein, the average channel quality parameter of all access bearers can adopt filtering algorithm to obtain, special, when each access bearer channel quality parameter changing value within the specific limits time, the average channel quality parameter of above-mentioned access bearer can adopt the ratio of the channel quality parameter sum of all access bearers and the number of access bearer, by the average channel quality parameter of this ratio as access bearer.

When channel quality parameter is signal to noise ratio, adopt following formula, obtain the Service Quality Metrics weighted factor of at least one carrying to be accessed:

${v_m}^{\&prime;}=\left\{\begin{array}{c}1-a\log \left(\frac{{\mathrm{SINR}}_{\mathrm{new}}+\left|k\right|}{\stackrel{\&OverBar;}{\mathrm{SINR}}+\left|k\right|}\right),{\mathrm{SINR}}_{\mathrm{new}}<\stackrel{\&OverBar;}{\mathrm{SINR}}\\ 1,{\mathrm{SINR}}_{\mathrm{new}}\&GreaterEqual;\stackrel{\&OverBar;}{\mathrm{SINR}}\end{array}\right.$ (formula three)

Wherein, v _m' be the Service Quality Metrics weighted factor of at least one carrying to be accessed; SINR _newfor the signal to noise ratio of at least one carrying to be accessed; for the average signal-to-noise ratio of access bearer; The channel quality parameter that in the channel quality parameter that k is access bearer described in all, value is minimum, ensures the validity of logarithmic function, preferably, when | when k| is non-integer, right | k| rounds up process; A is the first corrected parameter, can get positive count value, and preferably, a value is 0.8,1,1.5,2,3.

In addition, when channel quality parameter is signal to noise ratio, following formula can also be adopted, obtain the Service Quality Metrics weighted factor of at least one carrying to be accessed:

${v_m}^{\&prime;}=\left\{\begin{array}{c}{b}^{(\frac{{\mathrm{SINR}}_{\mathrm{new}}}{\stackrel{\&OverBar;}{\mathrm{SINR}}}-1)},{\mathrm{SINR}}_{\mathrm{new}}<\stackrel{\&OverBar;}{\mathrm{SINR}}\\ 1,{\mathrm{SINR}}_{\mathrm{new}}\&GreaterEqual;\stackrel{\&OverBar;}{\mathrm{SINR}}\end{array}\right.$ (formula four)
