Abstract
The present invention discloses a periodical measurement method for dedicated channels, which comprises: 1) setting a load threshold N and a periodic special measurement quantity optimal threshold M of RNC; 2) detecting whether the system load exceeds the N, if it is, executing the next step; 3) obtaining the information of cell that the UE corresponding to the wireless link for the special measurement belongs to, and judging whether the quantity of the UE corresponding to the wireless link for the periodic special measurement of the same type in the cell exceeds M, if it is, executing the next step; 4) stopping the measurement of all wireless links for the periodic special measurement of the same type in a node B, and performing the common measurement of the node B. in the invention, the node B, after passing the cell common measurement, reports ID of all UE and measurement information to the RNC, and the RNC identifies the measurement information of different UE based on the ID, as a result, the information between the Node B and the RNC are reduced greatly, the load of RNC is reduced, the measurement interval is shortened, and the measurement accuracy is improved.
Description
Technical field
The present invention relates to RNC (Radio Resource Control, radio network controller) and Node B (Node B), relate in particular to the periodical measurement method of Node B sub-district UE (User Equipment, subscriber equipment) dedicated channel.
Background technology
In the TD-SCDMA communication system, RNC manages Radio Resource according to various algorithms, as much as possible evade interference, elevator system capacity, satisfy QoS (the Quality ofService of miscellaneous service, service quality), the correct prerequisite of implementing of algorithm is to obtain various measured values, and measurement is the basis of algorithm.According to the measuring object difference, be divided into special measurement and public-measurement, present public-measurement is measured at Common Control Channel, and special measurement is measured at dedicated channel.Special measurement is used for the Radio Link of measure R NC at each UE correspondence, measures for every kind and distributes to measure an Id (Identification, sign), issue one and measure message, special measurement quantity is corresponding with the number that accesses terminal, and special measurement quantity is many more, and size of message is big more.Because when the special measurement size of message is excessive, can strengthen the RNC load, influence the regular traffic scheduling, wherein periodically special measurement is easier exerts an influence to system loading, often can only strengthen during processing and reduce size of message measuring period, influence measurement accuracy but add conference measuring period, and also do not have correlation technique to solve this problem at present.
Summary of the invention
Technical problem to be solved by this invention provides a kind of periodical measurement method to dedicated channel, reduces the load of RNC, guarantees the accuracy of measuring.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions:
A kind of periodical measurement method to dedicated channel may further comprise the steps:
(1) the load thresholding N of radio network controller and special measurement quantity optimization thresholding M periodically are set;
(2) whether radio network controller detection system load surpasses N, then enters next step if surpass;
(3) obtain the information of the subscriber equipment affiliated subdistrict of the Radio Link correspondence of carrying out special measurement, judge whether the subscriber equipment quantity of the Radio Link correspondence of the periodicity special measurement that carries out same type in this sub-district surpasses M,, then enter next step if surpass;
(4) Node B stops each carrier wave under the described sub-district all is carried out the measurement of Radio Link of the periodicity special measurement of same type, and these Radio Links are carried out public-measurement.
Wherein, in the described step (3), surpass M if carry out the subscriber equipment quantity of Radio Link correspondence of the periodicity special measurement of same type in the described sub-district, then Node B is ended under the described sub-district each carrier wave to the periodicity special measurement of all Radio Links, adjust all after dates of special measurement and initiate periodically special measurement again, finish this processing afterwards.
Wherein, described method also comprises: Node B is unit with the sub-district, gathers the metrical information of the Radio Link of all subscriber equipmenies, and each metrical information and radio network controller communication context sign are reported radio network controller.
Wherein, the report process method of described metrical information further comprises:
A, Node B are provided with to measure and report timer, and each carrier wave of sub-district reports to Node B according to timer with metrical information;
After b, Node B judged the equal report measurement information of each carrier wave of sub-district, summarizing and reporting information reported radio network controller with the radio network controller communication context sign and the metrical information of each all subscriber equipment of sub-district;
The information that c, radio network controller parse node B report identifies the metrical information that decomposites each subscriber equipment according to the radio network controller communication context.
Wherein, described method also comprises: the Radio Link of subscriber equipment adopts after the public-measurement in to the sub-district, if user device quantity is less than M in this sub-district, then described Radio Link is ended public-measurement, uses the special measurement mode instead.
Wherein, the termination method of described public-measurement further comprises:
A, radio network controller judge according to the reporting information of Node B whether user device quantity is less than thresholding M in the sub-district, if then notify Node B to start special measurement;
B, Node B receive notice back and start in the sub-district each carrier wave to the periodicity special measurement of the Radio Link of subscriber equipment, and response radio network controller special measurement starts successfully;
C, radio network controller notice Node B are ended public-measurement;
D, Node B are ended the public-measurement that each carrier wave carries out the Radio Link of subscriber equipment.
The present invention has following beneficial effect:
Among the present invention, Node B gathers the special measurement information of each sub-district UE, by report CRNC CC ID (radio network controller communication context sign) and the metrical information of all UE behind the public-measurement of sub-district to RNC, and RNC only need identify the metrical information of different UEs by CRNC CC ID, (as a community user number is N to a large amount of minimizings of message between Node B and RNC meeting like this, then message only is reduced to original 1/N), reduced the load of RNC, can shorten and measure at interval, improve the accuracy of measuring.Wherein, N and sub-district are formed relevant, for example, and TD-SCDMA 6 carrier cells, but access customer number surpasses 120, adopts the method for the invention, and it is original 1/120 that size of message reduces to, and can reduce the RNC load greatly.
