  2. UMTS - Wikipedia

    en.wikipedia.org/wiki/UMTS

    The Universal Mobile Telecommunications System (UMTS) is a 3G mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP (3rd Generation Partnership Project), UMTS is a component of the International Telecommunication Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology.

    UMTS Terrestrial Radio Access Network (UTRAN) is a collective term for the network and equipment that connects mobile handsets to the public telephone network or the Internet. It contains the base stations, which are called Node B 's and Radio Network Controllers (RNCs) [ 1 ] which make up the Universal Mobile Telecommunications System (UMTS ...

    en.wikipedia.org/wiki/Mobility_management

    Roaming is one of the fundamental mobility management procedures of all cellular networks.Roaming is defined [2] as the ability for a cellular customer to automatically make and receive voice calls, send and receive data, or access other services, including home data services, when travelling outside the geographical coverage area of the home network, by means of using a visited network.

  5. UMTS channels - Wikipedia

    en.wikipedia.org/wiki/UMTS_channels

    A point-to-point dedicated channel for transmitting user traffic information between a UE and the network. UL/DL 5.3.1.1.1 [4] 3_LOGICAL PCCH: paging control channel Transfers paging information. Used when the network does not know the location cell of the UE or the UE is in sleep mode. DL 5.3.1.1.1 [4] 2_TRANSPORT BCH: broadcast channel

  6. Node B - Wikipedia

    en.wikipedia.org/wiki/Node_B

    Node B is the telecommunications node for mobile communication networks, namely those that adhere to the UMTS standard. The Node B provides the connection between mobile phones and the wider telephone network. UMTS is the dominating 3G standard. Node B corresponds to BTS (base transceiver station) in GSM.

  7. Radio Network Controller - Wikipedia

    en.wikipedia.org/wiki/Radio_Network_Controller

    The Radio Network Controller (RNC) is a governing element in the UMTS radio access network and is responsible for controlling the Node Bs that are connected to it. The RNC carries out radio resource management, some of the mobility management functions and is the point where encryption is done before user data is sent to and from the mobile.

  8. Non-access stratum - Wikipedia

    en.wikipedia.org/wiki/Non-Access_Stratum

    Non-access stratum (NAS) is a functional layer in the NR, LTE, UMTS and GSM wireless telecom protocol stacks between the core network and user equipment. [1] This layer is used to manage the establishment of communication sessions and for maintaining continuous communications with the user equipment as it moves.

  9. Mobile Telephone Switching Office - Wikipedia

    en.wikipedia.org/wiki/Mobile_Telephone_Switching...

    Highly populated areas require more BTSs and BSCs/RNCs, which will in turn reduce the geographic coverage of a DMSC. The above in a MSC is what's considered as its mobility management. The BTS and BSC/RNC are the RAN/UTRAN (Radio Access Network & UMTS Radio Access Network) subset in the mobile network.
