Enhanced RRC release with redirect, automatic system info exchange with RIM (GSM & WCDMA)The standardized RIM procedures allow the transfer of SI from GSM or WCDMA to LTE. This requires additional impact on the total network. RIM needs to be rolled-out in the source and target RAN as well as for SGSN and MME. SGSN and MME will be needed to route the RIM container to the correct target node. Addi..

관련 LinkLTE Architecture and FEATURES This feature avoids reading SIBs with information that can be received at another occasion. Such information is included in SIB11 and 12. The SIB 11 includes measurement control and neighbouring cell list. As soon as a call is setup in Ericsson WCDMA, intra frequency measurements are started and the information in SIB11 information is retransmitted to the UE...

F-DPCH (Fractional Dedicated Physical CHannel) was first defined in 3GPP rel6 and then further enhanced in rel7 to overcome some soft handover limitations. Once HSDPA is used for the transfer of user data and L3 signalling (RRC & NAS) it allows the multiplexing of up to 10 users on a single SF 256 code for the purposes of sending TPC (Transmit Power Control) commands in the downlink. As shown in..

이동통신 3사 사업자들이 LTE-A 광고를 하며서 피를 튀기고 있습니다.제대로 된 서비스를 지원하지도 않으면서, 앞서 광고로 이미지 싸움을 하고 있는 것입니다.2011~2012년 부터 국내의 모든 이동통신망 사업자는 전국적으로 LTE 망 구축을 하였고, 이를 전국 방방곡곡까지 LTE가 되도록 서비스 확장에 힘을 쓰고 있습니다.그러면서 특정 지역에 LTE-A 서비스를 구축 후 실시 하였고, 지금은 이를 앞다투어 홍보하고 있는 것입니다. LTE를 알기 이전에, 우리가 지금까지 사용해 왔던, 그리고 지금도 사용하고 있는 3G를 이해해야 LTE를 이해가능 할 것 같습니다. UMTS 소개UMTS란 우리가 흔히 말해왔던 3G를 이야기 합니다.그럼 3G란? 3GPP(3rd Generation Partnership P..

Some intelligent UEs on a live network send a Signaling Connection Release Indication (SCRI) message to the RNC after PS data transmission is complete. By sending the SCRI message, intelligent UEs request for a transition to idle mode or the CELL_PCH or URA_PCH state to reduce battery consumption. Upon receiving the SCRI, the RNC can release the signaling connection and put the UE into idle mode..
