Abstract: A breakdown of voice over long term evolution (VoLTE) calls by adaptive multi-rate (AMR) speech coding mode may be determined by accessing a plurality of call detail records (CDRs) containing information associated with a plurality of corresponding communication sessions established over a mobile telephony network, and filtering the plurality of CDRs to obtain a subset of CDRs that are associated with communication sessions that used VoLTE services. A data structure containing correlations between AMR speech coding modes and bandwidth values may be referenced in order to classify the CDRs of the subset of CDRs into groups of different AMR speech coding modes. In some embodiments, a capacity planning metric or a resource allocation metric may be recommended based at least in part on numbers of the CDRs in the subset of CDRs within each of the groups of the different AMR speech coding modes.

Abstract: A method of determining a number of subscribers to a wireless communication network that access the wireless communication network via a wireless local access network (WLAN). For example, a session border gateway (SBG) or session border controller (SBC) located within the wireless communication network applies header manipulation rules (HMR) to messages sent and received within the wireless communication network in order to determine where the messages are being sent from and where the messages are being sent to. Based upon the information, it can be determined who the subscribers are that are sending the messages and receiving the messages and if they are connected to the wireless communication network via a WLAN. In embodiments, it can also be determined what type of messages are being sent and received based upon information in the headers obtained by the SBG or SBC.

Abstract: A method of determining initiation of video calls over a wireless communication network that uses counters within an application server. A number of video calls initiated on the wireless communication network utilizing a first wireless access technology during a period of time is determined by the counters. A number of video calls initiated on the wireless communication network utilizing a second wireless access technology during a period of time is determined by the counters. Based upon the counting, a percentage of video calls initiated on the wireless communication network utilizing the first and second wireless access technologies is derived.

Abstract: A method of determining video calls involved in a single radio voice call continuity (SRVCC) handover on a wireless communication network. Packet gateway (PGW) call data records (CDRs) are analyzed to determine a number of calls on the wireless communication network that are video calls during a period of time. The PGW CDRs are analyzed to determine a number of video calls involved in an SRVCC handover during the period of time. Based upon the determined number of calls that are video calls and on the determined number of video calls involved in an SRVCC handover, a percentage of video calls involved in an SRVCC handover during the period of time is derived.

Abstract: A breakdown of voice over long term evolution (VoLTE) calls by adaptive multi-rate (AMR) speech coding mode may be determined by accessing a plurality of call detail records (CDRs) containing information associated with a plurality of corresponding communication sessions established over a mobile telephony network, and filtering the plurality of CDRs to obtain a subset of CDRs that are associated with communication sessions that used VoLTE services. A data structure containing correlations between AMR speech coding modes and bandwidth values may be referenced in order to classify the CDRs of the subset of CDRs into groups of different AMR speech coding modes. In some embodiments, a capacity planning metric or a resource allocation metric may be recommended based at least in part on numbers of the CDRs in the subset of CDRs within each of the groups of the different AMR speech coding modes.
