Latest news and information on 3G and 4G wireless.
This is useful...I remember hearing about MBMS back in 2009 but not understanding it very much. Thank you!I have some questions about LTE, I wondered if you knew the answers:1) Does LTE use IMEIs? I can't find any info on that.2) I read the MME stores IMSIs permanently. So is the IMSI sent over the air during every initial attach (like now), or only the very first time??Thanks :)
Hi Anonymous, its always a good idea to provide some name. Your answers1. No it doesnt. I compiled a tutorial that is technical heavy (and for UMTS) if you want, its available at http://www.3g4g.co.uk/Tutorial/ZG/Mbms/2. MME does not store IMSI permenantly. Its stored in HLR or HSS. IMSI has to be sent over air interface when the UE is switched on for the first time or after long break otherwise TMSIs are used.
Hi Zahid,Can you pls provide 3GPP reference for slide 6 "Frame Structure for shared carriers". I specifically need to understand the subframe ratios and semi-static configuration as defined in specs.-Avin.
Please go through 36.440 and it should give you the right references.
Hi Zahid,Maybe it is an obvious question but if MCE is the responsible of radio resources scheduling and also it transmits MTCH to UEs, how MBMS-GW knows which contents to send and to who (MBSFN areas)?Thanks.Raúl.
Raúl, not sure what you mean but the MBMS-GW is responsible for telling the MCE on Control plane to setup resources and then it broadcasts the data on user plane directly to eNB on the M1 interface.
