Fig. 2 is the flow chart of the cut-in method embodiment bis-of terminal equipment of the present invention, and as shown in Figure 2, the method that the present embodiment provides comprises the following steps.
Step 201, the business information of obtaining terminal equipment and positional information.
Business information and positional information that macro base station obtains terminal equipment are specially, and the business information that receiving terminal reports and positional information, when terminal needs access network, are initiated access request to macro base station, and in access request, carried business information and positional information.
Step 202, according to the business information of terminal equipment and/or positional information, determine at least one adjacent little base station of terminal equipment.
The business information of terminal equipment has speech business, data service, multimedia service etc.Positional information refers to the positional information at the current place of terminal equipment, can obtain by global positioning system (Global Positioning System is called for short GPS) location, but be not limited to this.
Macro base station is determined at least one adjacent little base station of terminal equipment according to the positional information of terminal equipment, be specially, and determines a coverage centered by terminal equipment position, the little base station that is positioned at coverage is defined as to the adjacent little base station of terminal equipment.This coverage can be to take terminal equipment position to determine the circle that radius is R as initial point, the little base station that is positioned at circle is defined as to the adjacent little base station of terminal equipment, also can be the square centered by terminal equipment or the scope that other polygons were covered, the present invention be as limit.
Macro base station also can be determined according to the business information of terminal equipment at least one adjacent little base station of terminal equipment, based on business information, be mainly in order to adapt to the Future Data network architecture separated with signaling, in the Future Data network architecture separated with signaling, some base stations are used for carrier signaling specially, and data are only carried in other base stations.In this scene, according to the above-mentioned adjacent little base station of determining with geographical position, an if a certain little base station carry voice traffic, and terminal equipment request is multimedia service, although adjacent on this geographical position, little base station, because it does not support multimedia service, therefore can not can be regarded as the adjacent little base station of terminal equipment.Therefore, need to determine according to business information and positional information the adjacent little base station of terminal equipment.
At present, comprehensive business is mostly supported in base station, therefore, can only according to the geographical location information of terminal equipment, determine the adjacent little base station of terminal equipment.
Step 203, obtain wireless resource information and the state information of at least one adjacent little base station of terminal equipment, according to the wireless resource information of adjacent little base station and state information, determine the to be accessed little base station that at least one little base station is terminal equipment.
Macro base station obtains wireless resource information and the state information of at least one adjacent little base station of terminal equipment, after the wireless resource information and state information of adjacent little base station that gets terminal, according to the wireless resource information of each adjacent little base station and state information, consider the resource service condition of each adjacent little base station, comprise the information such as synchronizing signal, system information and pilot frequency design, determine the to be accessed little base station that at least one little base station is terminal equipment.
Take pilot frequency design as example, macro base station obtains the pilot frequency design of the adjacent little base station of terminal equipment, and according to the pilot frequency design of the adjacent little base station of terminal equipment, select pilot frequency design to distribute the minimum little base station of number, further, judge that this pilot frequency design distributes the load condition of minimum little base station, if this little load of base station is light, the to be accessed little base station using this little base station as terminal equipment, if this little base station is fully loaded, in the Multiple Small Cell Sites outside this little base station, select pilot frequency design to distribute the most when young base station as little base station to be accessed.Or, after selecting the minimum little base station of pilot frequency design distribution number, further comparing the pilot signal strength of each adjacent little base station, if the pilot signal that pilot frequency design distributes minimum little base station too a little less than, also be not suitable as little base station to be accessed, also need to from remaining Multiple Small Cell Sites, again determine little base station to be accessed.
Step 204, the access-in resource information of the little base station to be accessed of terminal equipment is sent to little base station to be accessed and terminal equipment.
Access-in resource information comprises: any one in synchronizing signal, system information and pilot frequency design or combination.Wherein, system information is used for the access information of terminal equipment to verify, and authentication etc., and system information also comprises bandwidth, standard of little base station etc.Terminal equipment is according to access-in resource information access little base station to be accessed.
The method that the present embodiment provides, before terminal equipment access, by macro base station, determine the adjacent little base station of terminal equipment and obtain wireless resource information and the state information of adjacent little base station, the relatively wireless resource information of each adjacent little base station and state information, the pilot frequency design that considers each little base station distributes number, pilot signal strength etc., select pilot frequency design to distribute the less little base station of number as little base station to be accessed, thereby can effectively avoid the pilot pollution between each community, realize the reasonable distribution of Internet resources.
Fig. 3 is the flow chart of the cut-in method embodiment tri-of terminal equipment of the present invention, and in the present embodiment, the terminal of take little base station to be accessed is not opened as example and illustrated, as shown in Figure 3, the method that the present embodiment provides comprises the following steps:
