MMTel - Multimedia Telephony over IMS

MMTel is a standardized solution to provide voice, video and other telephony services over LTE network (VoLTE). MMTel uses IMS to deliver voice, video and chat services to users. Along with that it specifies the way to share images, videos and files in real time. MMTel standard is a joint project by 3GPP (3rd Generation Partnership Project) and ETSI/TISPAN (European (more ..)

VoLTE end-to-end architecture

Comprehensive VoLTE – Voice Over LTE description with details on end-to-end architecture, call handling, roaming and handover to UMTS and GSM. LTE as its core is an all IP network in which data connectivity is given more importance than traditional voice and SMS services. But similar to its predecessors LTE eventually require a way to support CS and messaging services (more ..)

Self Organizing Network helps in reducing the system overload in an automated way. This new video from Ericsson describes what is SON and how Self Organizing Network will help not only LTE but also in older technologies like 3G and 2G. Automation creates value within the network and self organizing networks are increasingly important not only to lower costs of (more ..)

Voice over LTE (VoLTE)- Signalling

Voice over LTE – VoLTE is the technology to provide voice and video services over LTE all PS network. As LTE is a complete PS network VoLTE need to use IMS in EPS core to handle voice and video related services. Apart from IMS, VoLTE enabled UE (User Equipment) use MME (Mobility Management Entity) to authenticate a UE prior to (more ..)

Hetnet in LTE

Heterogeneous networks (HetNets), consisting of Macro NodeBs (macros) and low power Pico NodeBs (picos), can increase system capacity by offloading some users to the picos. However, this offloading may be limited due to intercell interference from macros to picos that reduces their coverage. HSPA Multi-carrier HetNets allow the use of range expansion techniques to achieve more offloading, such as power (more ..)

Volte Battery Test (LTE vs CDMA)

VoLTE was in bad limelight because of it’s battery performance issues. I wrote an article how VoLTE will consume twice battery than traditional voice calls. The study was done by Metrico Wireless using LG Connect 4G on MetroPCS network. ST Ericsson provided a new white paper which clarifies all doubts around VoLTE. Without VoLTE CDMA/LTE systems suffer a severe penalty (more ..)
