Solution overview
The long-distance coming call connection rate is a relatively important indicator for evaluating the mobile network quality. The increasing of long-distance coming call connection rate means not only improvement of the network quality but also the growth in telephone fare. The long-distance call connection process involves in massive network elements and is capable of measuring the network operation service quality scientifically. Due to its close association with the basic network maintenance quality, China Mobile pays high attention to the long-distance coming call connection rate and makes it become one of key network indexes to be evaluated.
The long-distance coming call network connection rate indicators optimization means to locate the key factors that affect the long-distance coming call connection rate by collecting and analyzing the long-distance coming call connection data and network call loss data and study the reasons that cause the long-distance coming call loss specially in order to offer a relevant effective measure.
The long-distance coming call network connection rate optimization solution is a set of special analysis product developed by ZCTT for the long-distance coming call network connection rate customization. It uses various characteristic analysis functions of the product to perform a deep mining analysis and location for the network connection rate and call loss reason, and provides a special solution.
China Mobile long-distance coming call network connection rate definition
Statistical range: BICC call record from tandem office to end office
Total occupied times = IAM message counts
Network connecting times = user answer + user release early + ringing release + ringing timeout (timeout release) + called reject + called busy + wrong number
Network connection rate = network connecting time/total call attempts * 100%
Network call loss times = wireless access fault (not in service area) + end to end congestion + other
Other = total call attempts – network connecting times – wireless access fault – end to end congestion
Network call loss rate = network call loss time/total call attempts * 100%
Product overview
The long-distance coming call network connection rate analysis product is mainly using its integrated long-distance coming call service record to implement the end-to-end association feature of each long-distance coming call interface and service record, and the core network and wireless network association analysis of long-distance coming call to provide special analysis functions such as the integrated long-distance coming call service record, China Mobile long-distance coming call network connection rate, long-distance coming call network connection rate call loss analysis, long-distance coming call paging unresponsive analysis, long-distance coming call wireless quality analysis, high long-distance coming call cell quality analysis and customized index analysis.
Product functions
1. Integrated long-distance coming call service record
Long-distance coming call service record is an end-to-end integrated service record of long-distance call.
The integrated service record can implement the multi-service signaling process association of one-time inter-office long-distance office to end-office record (BICC signaling process), long-distance office call-received record (BICC signaling process), inter-network record of end-office to its network, next-hop inter-office record of call forwarding generated by end-office, tone-ringing process, routing information over sending (MAP signaling process), roaming process providing (MAP signaling process), inter-office switch (MAP signaling process) end-office wireless-side MT record (BSSAP/RANNP signaling process) MO record of calling (BSSAP/RANNP signaling process).
It makes the association to various service records of each long-distance call interface and protocol to visualize the user service behavior, and provides convenience for maintenance personnel to make deep analysis on the network fault reasons.
2. China Mobile long-distance coming call network connection rate
This solution can provide the long-distance coming call network connection rate and call loss reason statistics as well as the trend analysis and distributional condition statistics of call result according to China Mobile long-distance coming call connection rate standards.
3. China Mobile long-distance coming call network connection rate call loss analysis
This analysis can perform the core network analysis and wireless network analysis of call loss to implement an association analysis to the core network and wireless network of long-distance coming call, improve the traditional long-distance coming call connection rate analysis method and find out the failed scenario of core-network call loss reason corresponding to the wireless network.
4. Long-distance coming call paging no response analysis
This analysis can perform a special analysis on wireless paging wireless call loss in the long-distance coming call loss analysis to implement its cause positioning, black hole cell of high paging failure affected by location, length of optimized cycle position updating and implicit shutdown time.
- No paging problem analysis of long-distance coming call
- Long-distance coming call paging quality analysis

5. Wireless quality analysis of long-distance coming call
The long-distance coming call connection rate in many cases is caused by the wireless-side problem, the long-distance coming call wireless quality analysis can offer a statistical analysis of each wireless indicator for long-distance coming call, and locate each wireless indicator of affecting the long-distance coming call.
- Long-distance coming call TCH channel establishment success rate analysis
- Long-distance coming call TCH channel congestion rate analysis
- Long-distance coming call TCH channel call-drop rate analysis
- Long-distance coming call SDCCH channel call-drop rate analysis
6. Quality analysis of high-proportional long-distance coming call cell
This analysis can perform a statistics to high-proportional long-distance coming call cell, locate the high valuable cell, perform a special quality analysis to high valuable cell and improve the service quality of high valuable cell according to the long-distance coming call service volume.
7. Customized analysis
It can provide a local customized analysis related to the long-distance coming call analysis based on the local requirements.
Application
Now, the long-distance coming call network connection rate special analysis solution has been applied successfully in many provinces.
