Without loss of generality, each embodiment hereinafter describing is applied to LTE system.Those skilled in the art will be understood that the technical scheme in the present invention can also be applied to other system.
Fig. 2 shows the method flow diagram that service is provided for a subscriber equipment in mobile communications network according to an embodiment of the invention.
As shown in the figure, the mobile communications network in this embodiment comprises at least one first kind base station 1, at least one Equations of The Second Kind base station 3, and a subscriber equipment 2.In this embodiment, for providing the method for service, subscriber equipment 2 comprises step: S1, S2, S4.
The application scenarios of this embodiment is as follows: about the access service of subscriber equipment 2, interference coordination is carried out in first kind base station 1 and Equations of The Second Kind base station 3.Such as but not limited to, first kind base station 1 and Equations of The Second Kind base station 3 correspond respectively to macro base station or microcell base station.
Scene one of the present invention is as follows: first kind base station 1 is that macro base station, Equations of The Second Kind base station 3 is microcell base station, the interference of the signal that communicating by letter between subscriber equipment 2 and macro base station 1 is subject to microcell base station 3.Such as but not limited to, microcell base station 3 is base station from home.Below in conjunction with Fig. 2, the method flow under this scene is described.
In step S1, macro base station 1 determine with microcell base station 3 between carry out the coordination relevant with the access of subscriber equipment 2, and sending a signaling to subscriber equipment 2, this signaling comprises coordinates Indication message and for the Special leader (preamble) of access microcell base station fast.
Particularly, step S1 comprises following sub-step:
-definite step of coordinating.Particularly, subscriber equipment 2 termly or burst ground send jamming report.The jamming report receiving when macro base station 1 shows larger from the interference signal of microcell base station 3, for example, while surpassing a predetermined threshold from the received power of the interference signal (at subscriber equipment 2) of microcell base station 3, macro base station 1 determine by with microcell base station 3 between carry out the coordination relevant with the access of subscriber equipment 2.
The step of-generation signaling.Particularly, macro base station 1 generates a signaling, and this signaling comprises coordinates Indication message and a Special leader for quick access microcell base station.In the present embodiment, that in system, uses is leadingly at least divided into two groups, comprising one group for the Special leader of access microcell base station fast.Conventionally, this group Special leader has higher priority, and microcell base station will be preferably the user equipment allocation resource of initiating access based on Special leader.
The step of-transmission signaling.Macro base station 1 sends to subscriber equipment 2 by the signaling that comprises coordination Indication message and Special leader generating.
In step S2, subscriber equipment 2 receives the signaling that macro base station 1 sends, and identifies the information in signaling, and the Special leader based on carrying in signaling is initiated access to microcell base station 3.
Particularly, subscriber equipment 2 is by monitoring the broadcast message of microcell base station 3, to obtain the configuration information of microcell base station 3, comprising the random access channel resource corresponding with Special leader.Then, subscriber equipment 2 sends this Special leader by using on the random access channel resource corresponding with this Special leader.
In step S4, when subscriber equipment 2 is obtained with after the synchronizeing of microcell base station 3, after being connected of namely subscriber equipment 2 access and microcell base station 3, subscriber equipment 2 is transmitted to microcell base station 3 by the coordination Indication message identifying among the signaling receiving from macro base station 1.
When microcell base station 3 receives, coordinate after indication information, will provide service according to its subscriber equipment that is designated as of coordinating Indication message, thereby avoid the interference between two class base stations.
If do not adopt Special leader, user probably will use Random Access Channel (the Random Access Channel based on competition in existing LTE system, RACH), when subscriber equipment is initiated access, may cause access failure and extend turn-on time because bump, thereby affect the coordination process between base station.
According to one embodiment of present invention, between above-mentioned steps S2 and S4, also has a step S3 (not shown).In step S3, microcell base station 3 is the Special leader that detects subscriber equipment 2 and send, and is subscriber equipment 2 Resources allocation.
