DETERMINING DROPPED CALL RATES IN IP MULTIMEDIA NETWORKS
First Claim
Patent Images
1. At least one non-transitory computer-readable medium carrying instructions, which when executed by at least one data processor, determine performance of an IP Multimedia System (IMS) network, comprising:
- identifying call detail records, wherein the identified call detail records include individual records that each include at least one Session Initiation Protocol (SIP) layer code associated with at least one session,wherein the at least one session has at least one failure within at least one application layer of a Voice over LTE (VoLTE) network;
computing a dropped call or failed session rate for the VoLTE network based on identified call detail records with SIP layer codes for sessions having failures; and
initiating an action based on the computed dropped call or failed session rate for the VoLTE network.

Abstract
Systems and methods are described herein for determining dropped call rates (DCR) for various communications networks, such as IP Multimedia Networks (IMS), which include Voice over LTE (VoLTE) networks. For example, the systems and methods utilize data (e.g. abnormal cause codes) generated by layers of the IMS networks, such as a Session Initiation Protocol (SIP) layer of the IMS network, when determining dropped call rates for IMS networks.

20. At least one non-transitory computer-readable medium carrying instructions, which when executed by at least one data processor, determine performance of an IP Multimedia System (IMS) network, comprising:
-
selecting call detail records having at least one cause code from a Session Initiation Protocol (SIP) layer associated with abnormal communication sessions for mobile devices having an IMS application layer; identifying a group of call detail records with cause codes associated with a dropped call within the IMS network; determining a dropped call rate for the IMS network based on the abnormal communication sessions for mobile devices having the IMS application layer within the identified group of call detail records; and performing an action based on the determined dropped call rate for the IMS network.
