Description
Technical field
The present invention relates to the communications field, in particular to a kind of base station selecting method and device.
Background technology
Along with the user group of radio communication gets more and more so that its application scenarios becomes more and more extensive, mobile Internet,
The fast development of Internet of Things and other service application has become as what the 5th third-generation mobile communication technology (5G) of promotion developed
Main drive.Therefore the demand of high-speed data service and ubiquitous access is just presenting a kind of explosive growth.
According to predicting the year two thousand twenty, portfolio, by for 1000 times of current operation amount, based on this, needs to promote broadband wireless and connects
The ability networked, adapts to future customer business demand.
For the demand of broadband wireless access, current European Union, China, Japan, the U.S. etc. all started for the 5th generation and move logical
The demand of communication system and key technology research.The Main Means promoting network throughput includes, promotes the biography of point-to-point link
Defeated speed, spread-spectrum resource, the heterogeneous network of high-density deployment；Wherein the heterogeneous network of high-density deployment will support mesh
20 to 30 times of front portfolio, in the network environment (Utra Dense Network, referred to as UDN) of high-density deployment
In, by reducing the area coverage of community, promote the spatial multiplex ratio of frequency spectrum resource, but although UDN small station can
The link-quality provided, but owing to the covering in small station is the least, it is impossible to well support that user's is quick mobile, therefore existing

And the medium node of load is received；
Finally, in constituting virtual subdistrict set, the signal intensity between itself and subscriber equipment is selected to reach to determine thresholding,
And the higher node of duty ratio is received.
Further, signaling PDU of a RRC information needs completely to send at a node；
Further, the chain of command of Master-BS needs to notify that user face RRC information needs the passage carrying out transmitting, than
Such as target BS mark or cell ID.
Two, the method that subscriber equipment selects up signaling transmission channels:
Step one: by subscriber equipment based on the channel between node and the subscriber equipment in the collection of base stations constituting virtual subdistrict
The load condition of the node in the collection of base stations of quality and virtual subdistrict determines to receive the base station of the signaling of rrc layer；
Step 2: when RRC signaling message sends, then base station based on subscriber equipment selection is as receiving RRC signaling
The passage of message.
Further, constitute virtual subdistrict collection of base stations in node and subscriber equipment between channel quality can by with
Family equipment self is measured and is obtained, and preserves most recent measurements；
Further, the factor weighing channel quality can be signal intensity or the signal interference ratio of reference signal, it is also possible to be
The signal intensity of pilot signal or signal interference ratio；
Further, subscriber equipment is also required to pass to subscriber equipment, Qi Zhongchuan for the thresholding monitoring channel quality states
The mode of passing can be to notify subscriber equipment by system broadcast message；
Further, build the non-Master-BS base station in the collection of base stations of virtual subdistrict and need to transmit the load letter of community
Breath is to subscriber equipment, and wherein transfer mode can be to notify subscriber equipment by system broadcast message；Wherein load letter
Breath may include that the load condition of current base station or community, the most high, medium and low instruction；
Further, subscriber equipment selects the method for signaling transmission channels to include:
Preferentially, in constituting virtual subdistrict set, select the signal intensity between itself and subscriber equipment best, and negative
The node that lotus is minimum is received；
Secondly, in constituting virtual subdistrict set, select the signal intensity between itself and subscriber equipment to reach certain thresholding,
And the minimum node of load is received；
Again, in constituting virtual subdistrict set, the signal intensity between itself and subscriber equipment is selected to reach certain thresholding,
And the medium node of load is received；
Finally, in constituting virtual subdistrict set, the signal intensity between itself and subscriber equipment is selected to reach certain thresholding,
And the higher node of duty ratio is received.
Further, signaling PDU of a RRC information needs completely to send at a node.
