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. The RNC connects to the Circuit Switched Core Network through Media Gateway and to the SGSN (Serving GPRS Support Node) in the Packet Switched Core Network.
An IP network to which a mobile set can be connected; A set of settings that are used for that connection; A particular option in a set of settings in a mobile phone; When a GPRS mobile phone sets up a PDP context, the access point is selected. At this point an Access Point Name (APN) is determined Example: aricenttechnologies.mnc012.mcc345.gprs
Some high end mobiles, usually also supporting UMTS, also support GPRS/EDGE multislot class 32. According to 3GPP TS 45.002 (Release 12), Table B.1, [18] mobile stations of this class support 5 timeslots in downlink and 3 timeslots in uplink with a maximum number of 6 simultaneously used timeslots. If data traffic is concentrated in downlink ...
Enhanced Data Rates for GSM Evolution (EDGE) (E-GPRS) and Universal Mobile Telecommunications System (UMTS) provide improved radio interfaces with higher data rates, while still being backward compatible with the GSM core network. Enhanced Circuit Switched Data (ECSD) was developed alongside GPRS/EDGE [2]
Phases 1 and 2 were defined before 3G networks existed, and as such support adding IN services to a GSM network, although they are equally applicable to 2.5G and 3G networks. Phase 3 was defined for 3GPP Releases 99 and 4, and hence is a GSM and UMTS common specification, while Phase 4 was defined as part of 3GPP Release 5.
The E220 connects to the computer with a standard Mini USB cable. The device comes with two cables, one short and one long. The long one has two USB A interfaces, one used for data and power and the other optionally only for assistance power in case the computer is not able to provide the full 500 mA (milliamperes) required for the device to work from one USB interface only.
In case a voice is started on a mobile phone that is in Packet Transfer Mode(i.e. in a data call), the procedure takes place in three stages. The TBF's (Data "Call") are released. A dedicated connection for the voice call is initiated. Finally, the mobile phone uses DTM for re-establishing the data connection.
System Architecture Evolution (SAE) is the core network architecture of mobile communications protocol group 3GPP's LTE wireless communication standard.. SAE is the evolution of the GPRS Core Network, but with a simplified architecture; an all-IP Network (AIPN); support for higher throughput and lower latency radio access networks (RANs); and support for, and mobility between, multiple ...
