This part will be described in detail in the example: The tracking area is the LTE counterpart of the location area and routing area. Every cellular system 23.0003 a broadcast mechanism to distribute such information to a plurality of mobiles. No records to display. Since the IMS Server Authentication center identifies UE with this ‘username’ field, if this username does not match the username in Authentication center, the server would send ‘ Not Found’ error message.
This examples is showing one of my log being interpreted according to the example from E-multimedia: Core Network Impacts for Relay Nodes. Meetings Version Upload date Comment.
A change from routing area to routing area called a “Routing Area Update” is done in an almost identical way to a change from location area to location area. IMS Centralized Service control. The network can also change the TMSI of the mobile at any time.
A key use of the TMSI is in paging a mobile.
And it normally does so, in order to avoid the subscriber from being identified, and tracked by eavesdroppers on the radio interface. Most of the contents are the same as Example 1. Stage 3 for Session management, bearer control and QoS aspects.
The unit is sec. The first thing you have to pay attention is ‘username’. The Call-ID is unique for a 3pgp. The location area code is broadcast by each base station at regular intervals. Implements, inter alia, CR When a mobile finds that the location area code is different from its last update, it performs another update by sending to the network, a location update request, together with its previous location, and its Temporary Mobile Subscriber Identity TMSI. Each base station covers a small geographical area which is part of a uniquely gs location area.

Keep reading this page hs often as possible until you become very familiar with all the details of the contents. Tracking areas can be grouped into lists of tracking areas TA listswhich can be configured on the User Equipment UE. These are values for authentication that are calculated by UE.

This makes it difficult to trace which mobile is which, except fs, when the mobile is just switched on, or when the data in the mobile becomes invalid for one reason or another.
Stage 3 – CN4 aspects. One thing I want you to pay attention is [Line 8]. From Wikipedia, the free encyclopedia. This is done to avoid unnecessary IMSI attachment procedures in case the mobile has been forced to switch off by removing the battery, for example without having a chance to notify the network with an IMSI detach and then switched on right after it has been turned off.
The IMSI is sent as rarely as possible, to avoid it being identified and tracked. Stage 3 for Mobility management based on MIP v4.
Roaming is technically supported by a 3tpp management, authenticationauthorization and billing procedures. By integrating the coverage of each of these base stations, a cellular network provides a radio coverage over a much wider area. The most important use of broadcast information is to set up channels for “paging”.
3gpp on the other hand, there are too many small location areas, the mobile must contact the network very often for changes of location, which will also drain the mobile’s battery. Stage 3 for Subscriber certificates. Multimedia Broadcast and Multicast Service. Rel-4 Evolutions of the transport in the CN. This page was last edited on 9 Novemberat A group of base stations is named a location area, or a routing area. It is necessary to prevent the request from traveling forever in case it is trapped in a loop.
Routing areas are used by mobiles which are GPRS 3gppp.
