Each TA of the list consists of one or more cells. , when the users are riding the same train). Furthermore, a TA list allocated to one UE naturally decreases the need of the UE to perform TA updates but it comes with the drawback of bigger paging areas (the concepts of TA updates and paging are described later in this chapter). 5 Spectrum Considerations To make LTE a worldwide success story, the technology must be flexible, adopt, and adapt to spectrum requirements in different countries around the globe.

These bands are listed in ITU-R Res 646 and are recommended for Public Safety use. Which bands will be actually used in which region depends on national regulation at the end. 1 Network Architecture Radio Access Network and Core Network A mobile network (also called Public Land Mobile Network – PLMN) is usually separated into a Radio Access Network (RAN) and a Core Network (CN). The functional elements are specified by 3GPP. 5). The RAN consists of all functions that are necessary to establish, maintain, and teardown connections between a user device (also called UE) and the network via the air interface.

The HSS provides also the security key KASME from which the MME derives the security keys to cipher and integrity protect NAS messages exchanged between UE Introduction to LTE/SAE 17 and MME. For location management purposes, the HSS stores the addresses of MME serving a particular UE. 8 Authentication, Authorization, and Accounting (AAA) Function The Authentication, Authorization, and Accounting (AAA) server (not shown in the various architecture figures) is either used to authenticate and authorize users who are accessing the EPC through non-3GPP access systems or, optionally, by the P-GW to authorize usage of the provided APN and to allocate an IP address to the UE.
