Description
Technical field
The present invention relates to the communications field, in particular to ANR collocation method, Apparatus and system.
Background technology
The service continuity that guarantees the mobile subscriber is a basic function of cell mobile communication systems, and the switching of travelling carriage Serving cell is the main means that guarantee service continuity.Switch for the ease of subscriber equipment (User Equipment abbreviates UE as), system need give each cell configuration syntople, so that network side notifies neighboring BS information to subscriber equipment; Subscriber equipment is measured back reporting measurement result according to neighboring BS information to the adjacent area, and network side indicates subscriber equipment to switch to a certain adjacent area according to the reporting measurement result again.
Have around certain sub-district which adjacent area not only with the sub-district distance dependent, and closely related with the residing wireless environment in sub-district.Because wireless environment is intricate, especially the intensive urban area circumstance of skyscraper is difficult to certain sub-district of definite judgement at the network planning initial stage and should disposes which adjacent area.Also have some to change the neighbouring relations of the sub-district that do not upgrade in time as having increased a sub-district or cell attribute in the system newly; The perhaps variation of environment, network planning personnel's omissions etc., it is untimely all can to cause neighboring BS information to upgrade.Will cause subscriber equipment can not in time switch to other sub-district like this, and make the generation of situation such as load too high, this cell signal degradation, serious interference or conversation loss of this sub-district.
Fig. 1 is the flow chart according to the method for obtaining neighboring BS information of correlation technique, and is as shown in Figure 1, may further comprise the steps:
Step S102: it reports indication (Automatic Neighboring Relationship abbreviates ANR as) capabilities message to service radio network control at the terminal.
Step S104: service wireless network controller judges whether this terminal is fit to carry out ANR.
Step S106: service wireless network controller issues the ANR configuration to the terminal.
Step S108: normal flow is carried out at the terminal, if at IDLE, cell_pch, ura_pch state carry out ANR, recording-related information down.
Step S110: the terminal is sent and is carried the message that there is indication in the ANR record.
Step S112: service wireless network controller sends the ANR information request to the terminal.
Step S114: the ANR recording responses is sent to service wireless network controller in the terminal.
Step S116: service wireless network controller transmits disappearance information to former sub-district to the terminal, is mirrored to Target cell, optimizes the forest zone tabulation, removes and there is no need the sub-district.
Need to prove that in the said process, when the terminal is in the configuration that special-purpose connected state is measured from moving neighboring BS relationship (ANR) at present, and prescribed terminal is at Idle state, the measurement of being correlated with during perhaps paging attitude.It is following to issue the Automatic Neighboring Relation measurement contents: any type ANR measures; The trigger condition of recording events, record duration, absolute time stranding and recording interval or the like; UE accomplishes the ANR measurement then; Report the existence of ANR report to give network side, network side sends the report situation of fetching then, last terminal to report request response.
To sum up, if this terminal is in the area that neighboring BS relationship need not upgrade, network side also issues ANR to this and measures, and can cause the waste of interface-free resources on the one hand, also can cause other neighboring BS relationship not upgrade in time on the other hand.
Can not get upgrading in time to adjacent area message in the correlation technique, cause the problem of call drop, do not propose effective solution at present as yet.
