UMTS – Wikipedia

Liaison statements. Releases. Work Plan. มาตรฐานของ UMTS ในปัจจุบันนั้นมีการเผยแพร่ออกมาแล้ว 4 มาตรฐานด้วยกัน โดยหน่วยงาน 3GPP (3G Partnership Project) รับหน้าที่ในการออกแบบมาตรฐานต่าง ๆ ซึ่งประกอบไปด้วย В долгосрочной перспективе, согласно проектам 3gpp, планируется эволюция umts в сети четвёртого поколения 4g, позволяющие базовым станциям передавать и принимать информацию на скоростях 100 Мбит/с и 50 Мбит/с 3gpp Umts Specifications And Management Information Technology Essay. The 2G data network started in the commercial level in the early 90’s. Then the cellular data network started growing in a rapid phase.

Dual Cell (DC-)HSUPA is the natural evolution of HSPA by means of carrier aggregation in the uplink. UMTS licenses are often issued as 10 or 15 MHz paired spectrum allocations. 3GPP message decoderis a very simple but powerful tool to decode GSM, UMTS, LTE, IP messages. This is developed by protocolanalyze.

3rd Generation Partnership Project – Wikipedia

Valbonne - FRANCE. The Third Generation Partnership Project (3GPP) was formed to coordinate the development of 3G Universal Mobile Telecommunications System (UMTS), but The third generation of mobile networks resulted from the global effort for unification of the mobile architecture and service delivery. In response to the International “UMTS-HSPA” refers to UMTS technology deployed in conjunction with HSPA capability.

MS identification: Cause value = 2 (IMSI unknown in HLR) This cause is sent to the MS if the MS is not known (registered) in the HLR. UMTS is an umbrella term for the third generation radio technologies developed within 3GPP. The radio access specifications provide for Frequency Division Duplex (FDD) and Time Division Duplex (TDD) variants, and several chip rates are provided for in the TDD option, allowing UTRA technology to operate in a wide range of bands and co-exist with other radio access technologies. The Universal Mobile Telecommunications System is a third generation mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP, UMTS is a component of the International Telecommunications Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology. UMTS uses wideband code-division multiple access radio access technology to offer greater spectral efficiency and bandwidth to mobile network 3GPP UMTS Specifications and Management. In order to create and manage a system as complicated as UMTS or WCDMA it is necessary to develop and maintain a large number of documents and specifications. For UMTS or WCDMA, these are now managed by a group known as 3GPP - the Third Generation Partnership Programme.

Close У довгостроковій перспективі, згідно з проектами 3gpp, планується еволюція umts в мережі четвертого покоління 4g, що дозволяють базовим станціям передавати і приймати інформацію на швидкостях 100 Мбіт/сек і 50 Мбіт/сек In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document. [1] 3GPP TS 23.110: "UMTS Access Stratum - Services and Functions". [2] 3GPP TS 22.100: "UMTS Phase 1". Written by experts actively involved in the 3GPP standards and product development, LTE for UMTS, Second Edition gives a complete and up-to-date overview of Long Term Evolution (LTE) in a systematic and clear manner.

Supported protocol stack layers: GSM (2G) : RLC - Radio Link Control, MAC, RRC - Radio Resource Control. UMTS (3G) : RRC - Radio Resource Control.

UMTS uses variable spreading and power levels to provide different user data rates. In FDD mode 10 msec frames are used The number of chips per bits is called the Spreading Factor (SF) and define the data service required for the user: T bit = SF x T chip For UMTS: Bit Rate x SF = 3.84 Mchips/s (Chip Rate) SF can change in every 10 msec frame Telcom 2720 26 3GPP specifications. The term "3GPP specification" covers all GSM (including GPRS and EDGE), W-CDMA (including HSPA), LTE (including LTE-Advanced and LTE-Advanced Pro) and 5G specifications. Revised versions of many of these specifications are produced up to four times a year following the quarterly TSG plenary meetings. 3GPP LTE är steget efter 3G inom mobil radiokommunikation. LTE införs i 3GPP release 8. LTE är inte samma sak som 4G, utan benämns som 3.9G.
