Abstract

Embodiments of the present disclosure provide an information acquiring method, parameter optimizing method and apparatuses thereof and a system. The method includes: receiving, by a first base station, information transmitted by user equipment, or a second base station, or a third base station; wherein, the information comprises relevant information used by a network side to determine cell types of the first base station and the second base station when handover initiation or link failure occurs, or comprises an absolute time when handover initiation or link failure occurs in the user equipment. With this method, cell types corresponding to coverage ranges of cells may be configured according to dynamically adjusted parameter ranges, thereby further configuring triggering conditions corresponding to the cell types, and satisfying traffic demands when the cell ranges change dynamically.

First claim

2 . The apparatus according to claim 1 , wherein the apparatus further comprises:
a type determining unit configured to determine the cell types of the first base station and the second base station when handover initiation or link failure occurs according to the relevant information.

3 . The apparatus according to claim 1 , wherein the apparatus further comprises: a first calculating unit configured to calculate the absolute time when handover initiation or link failure occurs in the user equipment according to the information relevant to time, in receiving the relevant information.

4 . The apparatus according to claim 2 , wherein the apparatus further comprises:
a detecting unit configured to detect whether to correct handover parameters between the first station and neighboring cells according to the information containing the cell types or the absolute time acquired within a predetermined time.

5 . An information acquiring apparatus, applicable to a second base station, comprising:
a second receiving unit configured to receive information notified by user equipment or a first base station or a third base station; wherein the information comprises relevant information used by a network side to determine cell types of the first base station and the second base station when handover initiation or link failure occurs, or comprises an absolute time when handover initiation or link failure occurs in the user equipment or information relevant to time.

6 . The apparatus according to claim 5 , wherein the apparatus further comprises:
a first notifying unit configured to notify the first base station of the information, in receiving the information notified by the user equipment or the third base station.

7 . The apparatus according to claim 5 , wherein the apparatus further comprises:
a second calculating unit configured to calculate the absolute time when handover initiation or link failure occurs in the user equipment according to the information relevant to time, in receiving the relevant information notified by the user equipment or the third base station; and a second notifying unit configured to notify the first base station of the absolute time.

8 . An information acquiring apparatus, applicable to a third base station, comprising:
a third receiving unit configured to receive information notified by user equipment; wherein the information comprises relevant information used by a network side to determine cell types of a first base station and a second base station when handover initiation or link failure occurs, or comprises information relevant to time; and a third notifying unit configured to notify the second base station or the first base station of the relevant information.

9 . The apparatus according to claim 8 , wherein the apparatus further comprises:
a third calculating unit configured to calculate an absolute time when handover initiation or link failure occurs in the user equipment according to the information relevant to time; and a fourth notifying unit configured to notify the second base station or the first base station of the absolute time.

10 . A parameter optimizing apparatus, comprising:
a first transmitting unit configured to notify information containing cell types of a source cell and a target cell or containing an absolute time period indicating frequent occurrence of handover failure to a base station where a cell needing to be corrected with respect to parameters is located, in detecting that handover parameters between a base station where the apparatus is located and neighboring cells need to be corrected.

11 . The apparatus according to claim 10 , wherein the apparatus further comprises:
a fourth receiving unit configured to receive a response message capable of correcting the handover parameters fed back by a neighboring base station; and a parameter correcting unit configured to correct the handover parameters according to the response message.

12 . A parameter optimizing apparatus, comprising:
a fifth receiving unit configured to receive information containing cell types of a source cell and a target cell or containing an absolute time period indicating frequent occurrence of handover failure transmitted by a parameter-correcting base station; a determining unit configured to evaluate according to the information whether to correct handover parameters; and a second transmitting unit configured to transmit a corresponding response message to the parameter-correcting base station when an evaluating result of the determining unit is to correct the handover parameters.

13 . A parameter configuring method, comprising:
determining coverage ranges of cells by a base station or an OAM according to parameter ranges of configured more than one group of parameter sets; configuring cell types corresponding to the coverage ranges of cells; wherein the cell types denoted by the parameter.

14 . (canceled)

15 . The method according to claim 13 , wherein the method further comprises:
notifying the configured cell types by the OAM to a base station.

16 . The method according to claim 15 , wherein the method further comprises:
notifying, by the base station or the OAM, information on a changed cell type to a network side neighboring base station when the coverage ranges of cells change.

17 . A parameter configuring apparatus, comprising:
a first parameter configuring unit configured to determine coverage ranges of cells according to parameter ranges of configured more than one group of parameter sets; a second parameter configuring unit configured to configure cell types corresponding to the coverage ranges of cells; wherein the cell types denoted by the parameter.
