8.41 Packet TMSI (P-TMSI) 29.274 3GPP 3GPP Evolved Packet System (EPS) Evolved General Packet Radio Service (GPRS) Tunnelling Protocol for Control plane (GTPv2-C) Release 16 Stage 3 TS.
LTE stands for Long Term Evolution and it was started as a project in 2004 by telecommunication body known as the Third Generation Partnership Project (3GPP). De manière identique, lorsque l’UE quitte le réseau 4G vers le 3G, le GUTI est … The CO-RNTI is carried as a part of the MAC header of the control packets transmitted from an eNB to eUE in order to establish the VL.

on the fifth expiry of timer T3350, the network shall abort the P-TMSI reallocation procedure and shall follow the rules for case a as described above.c) P-TMSI reallocation and GPRS attach procedure collision If the network receives an ATTACH REQUEST message before the ongoing P-TMSI reallocation procedure has been completed, the network shall proceed with the GPRS attach procedure after deletion of the GMM context.d) P-TMSI reallocation and an MS initiated GPRS detach procedure collision If the network receives a DETACH REQUEST message before the ongoing P-TMSI reallocation procedure has been completed, the network shall abort the P-TMSI reallocation procedure and shall progress the GPRS detach procedure.e) P-TMSI reallocation and a routing area updating procedure collision If the network receives a ROUTING AREA UPDATE REQUEST message before the ongoing P-TMSI reallocation procedure has been completed, the network shall abort the P-TMSI reallocation procedure and shall progress the routing area updating procedure. The network knows the location of the UE to the granularity of a few cells, called the Tracking Area (TA). Outside the routing area the P-TMSI has to be … IMSI IMSI refers to ‘International Mobile Subscriber Identity’, […] Top. paging and Service Request).In the case of multi-hop relaying, the optional second-stage access station selection is performed after the neighbor station measurement reporting and before the RS operational parameter configuration phases. Why in LTE have created temorary ID 80 bit dont you think it will consume lot of signalling radio BW.Into GUTI structure there's an small error: second GUMMEI field is MNC (not MCC again) ;-)If the GUTI is wrong , will the signaling stop after SIB2 Msg? The signaling corresponding to state transitions and radio bearer configurations should be performed by RRC sub-layer due to signaling reliability. The globally unique identifier in GPRS has no explicit name but by combining the RA ID (RAI) and the P-TMSI you get a globally unique identifier.
The RLC provides three different reliability modes for data transport, i.e., acknowledged mode (AM), unacknowledged mode (UM), and transparent mode (TM). The AAI_DSC-RSP message is generated in response to the AAI_DSC-REQ message inclusive of the following parameters:In response to an AAI_DSC-REQ message which contains SCID, the SCID may be included in an AAI_DSC-RSP message to accept the base station or mobile station’s request. 7. Si l’UE était initialement enregistré sur le réseau 3G ce dernier possède un identifiant P-TMSI. Furthermore, there are two levels of re-transmissions for providing reliability, the HARQ at the MAC layer, and ARQ at the RLC layer. Tag: P-TMSI. The TMSI is used instead of IMSI to protect subscriber from being identified and also make life more difficult to radio interface eavesdroppers.Because of that when UE is contacting the network it sends the GUTI to the eNodeB which then uses the GUTI number to identify to which MME re-establish request will be send. The HARQ within the MAC layer is characterized by an N-process stop-and-wait protocol and re-transmission of transport blocks upon failure of earlier transmissions.
