Embodiment
The embodiment of the invention provides a kind of abnormality eliminating method, system and device of RRU load sharing pattern, after auxilliary optical fiber breaks down, bearing capacity according to other optical fiber, need to determine the carrier wave and/or the antenna amount of minimizing, and close the carrier wave and/or the antenna of respective numbers, thereby realize the processing that degrades is served in the sub-district, truly reflect the service ability of sub-district, and then improve the disposal ability of sub-district after auxilliary optical fiber breaks down.
As shown in Figure 2, the abnormality eliminating method of the RRU load sharing pattern that provides of the embodiment of the invention comprises:
Step S201, determine that auxilliary optical fiber is unusual after, obtain to reduce the indication of carrier wave and/or antenna, and determine the carrier wave of required minimizing and/or the minimum total amount of antenna;
Step S202, the described RRU of indication reduce the carrier wave and/or the antenna of respective numbers.
Because under the indication of BBU (Base Band Unit, Base Band Unit), RRU has reduced the carrier wave and/or the antenna of respective numbers, has carried out the sub-district processing that degrades, so can reflect the real ability state of sub-district.Can also further handle, thereby further improve the disposal ability of sub-district according to demand.
In step S201, BBU obtains to reduce the indication of carrier wave and/or antenna, can specifically adopt to RNC (Radio Network Controller, radio network controller) and send the resource status indication, and receive the mode of the indication of minimizing carrier wave that described RNC returns and/or antenna.
BBU can determine that auxilliary optical fiber is unusual by the auxilliary optical fiber abnormality warnings that reception RRU reports.
BBU can also determine the number of carriers and the antenna amount of required minimizing respectively, and the number of carriers and the antenna amount of required minimizing are indicated to RRU, thereby after making that RRU closes the carrier wave and/or antenna of respective numbers, can obtain preferable disposal ability.At this moment, BBU also according to community user quantity and predefined minimum antenna amount, determines the number of carriers and the antenna amount of required minimizing respectively before indication RRU reduces the carrier wave and/or antenna of respective numbers.
Under application scenes, BBU can not accurately judge the number of carriers and the antenna amount of required minimizing, at this moment, according to community user quantity and predefined minimum antenna amount, determine the number of carriers and the antenna amount of required minimizing respectively, indication RRU reduces the carrier wave and/or the antenna of respective numbers, specifically comprises: the carrier wave of indication RRU deletion and minimum total amount similar number; The antenna amount of determining cell carrier off-capacity and unlatching is during greater than predefined minimum antenna amount, and indication RRU is that unit increases carrier wave with single carrier wave, closes the antenna identical with the number of carriers that is increased simultaneously.
Like this, RRU then can from only reducing number of carriers, according to number of users and antenna amount lower limit, improve number of carriers gradually according to the indication of BBU, up to the demand that satisfies the user, obtains preferable disposal ability.
For further obtaining better disposal ability, satisfy user's demand, number of carriers that is reduced and antenna amount can be regulated according to the variation of number of users in the sub-district, a kind of concrete regulative mode can for: when number of users increase in the sub-district causes the antenna amount of cell carrier off-capacity and unlatching greater than predefined minimum antenna amount, indication RRU is that unit increases carrier wave with single carrier wave, closes the antenna identical with the number of carriers that is increased simultaneously; When user in the sub-district reduces and the antenna amount opened during less than maximum antenna quantity, indication RRU is a unit deletion carrier wave with single carrier wave, opens the antenna identical with the number of carriers of being deleted simultaneously.
Wherein, BBU can determine that the number of users increase causes user's minimizing in cell carrier off-capacity or the definite sub-district in the sub-district by the Indication message that receives the RNC transmission.
In order to guarantee after changing antenna amount, the coverage of antenna is bigger, can behind each change antenna amount, reconfigure antenna parameter, at this moment, BBU also need be behind each change antenna amount, determine antenna parameter according to current antenna amount, and indicate RRU to reconfigure antenna parameter, wherein, the change antenna amount comprises closes antenna and opens antenna, promptly reduces number of antennas and increases number of antennas.
