Currently, in a communication system that detects link quality through a link quality monitoring algorithm (RLS algorithm for short), such as a TD-SCDMA communication system or an LTE communication system, when detecting that link quality is deteriorated, whether air interface adjustment is needed to improve user quality is determined according to an interference situation of a time slot where a current user is located, or RSCP (Received Signal Code Power) values of a serving cell and a target cell.
In such prior art schemes, when the link quality is determined to be degraded by the link monitoring algorithm, i.e., when air interface adjustments are attempted, such as intra-system handovers, traffic rate adjustments, timeslot/carrier frequency adjustments, etc., it is possible to increase the probability of dropped calls for users. Firstly, in some areas, when the pilot frequency value received by the user is very low, the network side sends a Uu port message to the terminal at the moment, and the terminal is likely to fail to receive the signal due to weak signal, so that the network side cannot respond to the message in time to cause call drop; secondly, for a certain area, there is a possibility that signals of adjacent cells to the area are not strong, so when detecting the link quality deterioration, trying to adjust to the adjacent TD cell or making time slot adjustment in the cell cannot completely alleviate the link quality deterioration caused by weak coverage, and the RLS algorithm effect will be affected. Through analyzing the field test result, the call drop rate of the air interface adjustment performed by the RLS algorithm is deteriorated after the RLS algorithm is started in a part of areas.
It can be seen that the link quality monitoring algorithm of the current communication system, such as TD-SCDMA, may cause the misadjustment of the air interface, increasing the probability of user call drop.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Example one
Referring to fig. 1, a flow chart illustrating steps of an air interface adjustment method according to a first embodiment of the present application is shown.
The air interface adjusting method of the embodiment comprises the following steps:
step S102: the communication system network side determines that the link quality of the current cell in which the mobile terminal is located is deteriorated.
For example, the RNC or the base station on the network side of the communication system determines that the link quality of the cell in which the mobile terminal is currently located is degraded according to the received link quality measurement report. The judgment standard of the link quality deterioration is the same as that of the existing communication network such as TD-SCDMA network, and is not described herein again.
Step S104: the network side of the communication system judges whether the current cell where the mobile terminal is located is a weak coverage area; and if so, adjusting the air interface of the mobile terminal according to the set adjustment strategy.
Wherein, the set adjustment strategy comprises at least one of the following: the strategy, the inter-system switching strategy and the intra-system speed reduction strategy are not adjusted; the non-adjustment strategy is used for indicating that when the current cell where the mobile terminal is located is a weak coverage area, the air interface of the mobile terminal is not adjusted; the inter-system switching strategy is used for indicating that the inter-system switching is carried out on the mobile terminal when the current cell where the mobile terminal is located is a weak coverage area; the in-system speed reduction strategy is used for indicating that when the current cell where the mobile terminal is located is a weak coverage area, the air interface adjustment for reducing the service rate is carried out on the mobile terminal in the current system where the mobile terminal is located.
The judgment of whether the current cell in which the mobile terminal is located is a weak coverage area can adopt different judgment strategies according to different communication systems. For example, for the TD-SCDMA system, it can be determined whether the pilot value of the current cell where the mobile terminal is located is lower than a set threshold, and if so, the current cell is determined to be a weak coverage area; for the LTE system, it may be determined whether an RSRP (Reference Signal Receiving Power) value of a current cell where the mobile terminal is located is smaller than a set threshold, and if so, the current cell is determined to be a weak coverage area.
By the embodiment, a link quality monitoring scheme combined with weak coverage area judgment is provided, and when the link quality is detected to be deteriorated, whether the user performs air interface adjustment according to a set adjustment strategy at the moment is determined by combining the coverage area condition of the user. By the scheme of the embodiment, in which the quality of the radio link is monitored and whether the user is in the weak coverage area is combined, for the user in the weak coverage area, when the user is monitored to be in the weak coverage area, the air interface can be adjusted through a customized adjustment strategy. Therefore, in practical application, the adjusting strategy of the RLS algorithm can be flexibly configured by combining the coverage conditions of the cell and the adjacent cell, the judgment of the weak coverage area is automatically realized, and the corresponding air interface adjustment is executed, so that the effect of the RLS algorithm is fully exerted, the call drop caused by blind adjustment in the weak coverage area is reduced, and the problems that the air interface misadjustment possibly caused by the utilization of a link quality monitoring algorithm in the conventional communication system and the call drop probability of a user are increased are solved.
Example two
Referring to fig. 2, a flowchart illustrating steps of an air interface adjusting method according to a second embodiment of the present application is shown.
The present embodiment takes TD-SCDMA system as an example to explain the air interface adjustment scheme of the present application. It should be clear to those skilled in the art that, for other communication systems that perform air interface adjustment through link quality monitoring, the air interface adjustment scheme of the present application can be implemented with reference to the present embodiment.
The air interface adjusting method of the embodiment comprises the following steps:
step S202: the network side of the communication system receives a link quality measurement report of a current cell in which the mobile terminal is located.
For example, the RNC of the TD-SCDMA system receives a link quality measurement report sent by a base station or a terminal.
Step S204: the network side of the communication system judges whether the link quality of the current cell where the mobile terminal is located is deteriorated, if so, step S206 is executed; if not, the air interface adjustment processing is not carried out.
Step S206: the network side of the communication system judges whether the current cell where the mobile terminal is located is a weak coverage area, if so, step S208 is executed; if not, go to step S212.
In this embodiment, a RSCP threshold for judging a weak coverage area is set, and when the pilot value of the current cell in which the mobile terminal is located is lower than the RSCP threshold, or the pilot value of the current cell in which the mobile terminal is located is not reported in the link quality measurement report, the mobile terminal may be considered to be currently in the weak coverage area, that is, the current cell in which the mobile terminal is located is the weak coverage area.
Step S208: the network side of the communication system inquires the RLS algorithm weak coverage strategy library and determines an adjustment strategy for adjusting the air interface of the mobile terminal in the weak coverage area.
The RLS algorithm weak coverage strategy base stores the air interface adjustment strategy when the mobile terminal is in the weak coverage area. As previously mentioned, these adjustment policies may be one or more of an un-adjustment policy, an inter-system handover policy, and an intra-system slowdown policy. When the adjustment policy includes a plurality of non-adjustment policies, inter-system handover policies, and intra-system speed reduction policies, each policy may set a different priority, where when the plurality of policies includes a non-adjustment policy, the priority of the non-adjustment policy is the lowest priority. At this time, the adjustment of the air interface of the mobile terminal is executed according to the different priorities of various strategies, and only when the strategy execution of the high priority level fails, the strategy of the lower priority level is executed. For example, the policy for air interface adjustment of the mobile terminal may be set to: according to the non-adjustment strategy, when the current cell is a weak coverage area, the air interface of the mobile terminal is not adjusted; or, according to the inter-system switching strategy and the intra-system speed reduction strategy, when the current cell is a weak coverage area, the inter-system switching is firstly carried out on the mobile terminal; if the switching between the systems fails, the air interface of the mobile terminal for reducing the service rate is adjusted in the current system; or, according to the intra-system speed reduction strategy and the inter-system switching strategy, when the current cell is a weak coverage area, firstly, the air interface of the mobile terminal for reducing the service rate in the current system is adjusted; if the air interface adjustment for reducing the service rate fails, the mobile terminal is switched between systems. But not limited thereto, those skilled in the art may also flexibly select an adjustment policy according to the actual situation, and appropriately set the priority to perform air interface adjustment of the mobile terminal, for example, set to execute the inter-system handover policy first, and execute the non-adjustment policy if the inter-system handover fails, or set to execute the intra-system speed reduction policy first, execute the inter-system handover policy if the intra-system speed reduction policy fails, and execute the non-adjustment policy if the inter-system handover policy also fails, etc. By setting the priority, the air interface adjustment strategy set according to the actual situation can be ensured to be preferentially executed, and the adaptability and the efficiency of the air interface adjustment are improved.
In this embodiment, the policy for adjusting the air interface of the mobile terminal includes: (1) the strategy is not adjusted, namely the adjustment strategy of the mobile terminal in the weak coverage area is set to be not operated; (2) firstly, switching between systems and then adjusting the strategy in the system, namely configuring the adjustment strategy when the mobile terminal is in a weak coverage area as the strategy for switching between systems firstly and then trying the adjustment strategy in other systems; (3) firstly, the strategy of intra-system adjustment and then inter-system switching is set, namely the adjustment strategy when the mobile terminal is in a weak coverage area is set as the strategy of firstly carrying out intra-system adjustment, namely reducing the service rate, and then carrying out inter-system switching. The above-mentioned strategies can be set alternatively by those skilled in the art according to actual situations, so as to perform air interface adjustment of the mobile terminal in the weak coverage area. For example, if the system determines that the network interference for the mobile terminal to switch over is large, the (1) th non-adjustment strategy may be adopted; if the system judges that the network condition for switching the mobile terminal is better and the interference is smaller, the strategy of the (2) type can be adopted; if the system determines that the mobile terminal needs to be left in the current network as much as possible according to the configuration, the (3) th strategy can be adopted.
Step S210: and the communication system network side carries out air interface adjustment on the mobile terminal in the weak coverage area according to the determined adjustment strategy, and finishes the air interface adjustment process.
Step S212: the network side of the communication system inquires a strategy base configured by the RLS algorithm in a default mode, and determines a system default adjusting strategy for adjusting the air interface of the mobile terminal in the non-weak coverage area.
The strategy base of the RLS algorithm default configuration stores the air interface adjustment strategy of the system default configuration, such as the original air interface adjustment strategy of the TD-SCDMA system, and the original adjustment strategy of the system can be the strategy of intersystem switching and/or intra-system adjustment. When the mobile terminal is in a non-weak coverage area, the intra-system adjustment includes cell switching, carrier frequency adjustment, time slot adjustment, rate adjustment, and the like.
Step S214: and the communication system network side carries out air interface adjustment on the mobile terminal in the non-weak coverage area according to the determined adjustment strategy, and finishes the air interface adjustment process.
By the embodiment, when the network side of the communication system detects that the link quality of the mobile terminal is deteriorated, firstly, whether the mobile terminal is in the weak coverage area is judged, and secondly, the mobile terminal in the weak coverage area can customize a specific air interface adjustment strategy. The TD wireless link quality monitoring algorithm provided in this embodiment combines the idea of whether the user is in the weak coverage area, and for the user in the weak coverage area, when the network monitors that the user is in the weak coverage area, the adjustment strategy can be customized for this scenario. Therefore, in practical application, the adjustment strategy of the RLS algorithm can be flexibly configured by combining the coverage conditions of the cell and the adjacent cell, the judgment of the weak coverage area is automatically realized through a program, and corresponding adjustment is executed, so that the effect of the RLS algorithm is fully exerted, and the call drop caused by blind adjustment in the weak coverage area is reduced.
