Abstract
The invention discloses an access control method used for an LTE system. The access control method used for the LTE system includes the steps that clients send access requests to some access point; the access point obtains the intensities of all antenna unit pilot signals received by users requesting access and groups antenna units and the users according to the intensities of the signals; the corresponding relations between the users and the antenna units are established by the access point according to the grouping result, and a serving cell is established with one of the antenna units as the center; the access point obtains the intensities of the pilot signals, received by the users, of all the antenna units except the serving antenna unit and selects the next antenna unit for the users. Through the access control method, the number of required antenna units can be reduced as much as possible, the access time is shortened, the resource utilization rate of the system is increased, and interference caused to other users in the system is made minimum while it is guaranteed that the resources used by the users currently can meet requirements of the users.
Description
Technical field
The invention belongs to the communications field, a kind of connection control method for LTE system.
Background technology
For each user who wishes connecting system, access point is selecting antenna element while forming the group of mean people district communicating with it, the problem that exists some to solve.How for example access point ensures to select the unit of guaranteeing multiple antenna compositions of selecting to provide satisfied service quality for new user, the antenna element number that how to confirm is selected, and how to bring into play the optimum performance of community.
Prior art has proposed several different methods; for example CN102246582 discloses a kind of method; comprise: in the time that carrier convergence community is asymmetric carrier convergence community; obtain the information that do not enter of setting up in the system message of descending component carrier, described in the information that do not enter of setting up be used to indicate described in LTE-A UE carrier convergence community whether can with or described descending component carrier whether can use; When the described information that do not enter of setting up is while being available, on described descending component carrier, carry out community selection/reselection or initially access.This method has solved subproblem to a certain extent, but the performance of system is not given full play to.
Summary of the invention
Goal of the invention: provide a kind of connection control method for LTE system, to solve the problems referred to above of prior art.
Technical scheme: a kind of connection control method for LTE system, comprises the steps:
Step 1: user side sends access request to certain access point;
Step 2: the intensity of each antenna element pilot signal that the user of described access point acquisition request access receives, according to the intensity of signal, each antenna element and user are divided into groups;
Step 3: access point, according to group result, is set up the corresponding relation of user and antenna element, and select one of them antenna element as center, set up Serving cell, and be user assignment idling-resource,
Step 4: access point obtains the Signal to Interference plus Noise Ratio that whether is less than user's requirement when bundle of services community that the access antenna element of current selection forms is used institute's Resources allocation and telex network to be for receiving total Signal to Interference plus Noise Ratio of signal; If not, access successfully, finish this process; If so, judge whether access number of times reaches maximum constraints, if otherwise return to step 3;
Step 5: access point obtains the intensity of the each antenna element pilot signal except service antenna unit that user receives, and select next antenna element for user, ensure that all antenna elements in current service group of mean people district use identical resource to provide service for user with the chosen antenna element that newly adds, and added current service group of mean people district.
Step 2 further comprises: be divided into multiple according to the intensity of antenna element pilot signal, according to the height of intensity successively by the 1st, 4 ... individual antenna element is put into first group, 2nd, 5 ... individual antenna element is put into second group, and the 3rd, 6 antenna elements are put into the 3rd group.
The corresponding relation of setting up user and antenna element in step 3 specifically comprises: set up user and can receive between all antenna elements of signal strength signal intensity higher than a certain threshold value and set up relation corresponding to meaning with it, evaluate the effectiveness that can obtain when this user accesses a certain antenna element, set up community for user selects first optimum antenna element, and further select optimum resource; Assess the QoS requirement whether this community can meet user, can not meet while asking demand when counting after first antenna element, select another unit access, further expanding as user provides the community of service.
Step 5 also comprises, occupied when a certain antenna element, changes other slack resources for this user's service, and from slack resources storehouse, selects optimum resource composition service groups.
Beneficial effect: the present invention can cross and can reduce needed antenna element number as far as possible, reduce the access time used, improve resource utilization ratio, in ensureing that the currently used resource of user can be met consumers' demand, to intrasystem other users' interference minimum.
Embodiment
For a connection control method for LTE system, comprise the steps:
Step 1: user side sends access request to certain access point;
Step 2: the intensity of each antenna element pilot signal that the user of described access point acquisition request access receives, according to the intensity of signal, each antenna element and user are divided into groups; Be divided into according to the intensity of antenna element pilot signal multiple, according to the height of intensity successively by the 1st, 4 ... individual antenna element is put into first group, and the 2nd, 5 ... individual antenna element is put into second group, and the 3rd, 6 antenna elements are put into the 3rd group;
Step 3: access point, according to group result, is set up the corresponding relation of user and antenna element, and select one of them antenna element as center, set up Serving cell, and be user assignment idling-resource;
Setting up user can receive between all antenna elements of signal strength signal intensity higher than a certain threshold value and set up relation corresponding to meaning with it, evaluate the effectiveness that can obtain when this user accesses a certain antenna element, set up community for user selects first optimum antenna element, and further select optimum resource; Assess the QoS requirement whether this community can meet user, can not meet while asking demand when counting after first antenna element, select another unit access, further expanding as user provides the community of service.
Step 4: access point obtains the Signal to Interference plus Noise Ratio that whether is less than user's requirement when bundle of services community that the access antenna element of current selection forms is used institute's Resources allocation and telex network to be for receiving total Signal to Interference plus Noise Ratio of signal; If not, access successfully, finish this process; If so, judge whether access number of times reaches maximum constraints, if otherwise return to step 3;
Step 5: access point obtains the intensity of the each antenna element pilot signal except service antenna unit that user receives, and select next antenna element for user, ensure that all antenna elements in current service group of mean people district use identical resource to provide service for user with the chosen antenna element that newly adds, and added current service group of mean people district.Occupied when a certain antenna element, change other slack resources for this user's service, and from slack resources storehouse, select optimum resource composition service groups.
