Что (кто) такое GSM PLMN connection - определение

SPEECH CODING STANDARD

GSM 06.20; GSM-HR

Connection pool

CACHE OF DATABASE CONNECTIONS MAINTAINED BY THE DATABASE

Connection pooling; Connection Pool

In software engineering, a connection pool is a cache of database connections maintained so that the connections can be reused when future requests to the database are required.

Connection (vector bundle)

$How to recover the covariant derivative of a connection from its parallel transport. The values <math>s(\gamma(t))</math> of a section <math>s\in \Gamma(E)</math> are parallel transported along the path <math>\gamma</math> back to <math>\gamma(0)=x</math>, and then the covariant derivative is taken in the fixed vector space, the fibre <math>E_x</math> over <math>x</math>.$

LINEAR CONNECTION ON A VECTOR BUNDLE

Koszul connection; Vector bundle connection; Connection on a vector bundle

In mathematics, and especially differential geometry and gauge theory, a connection on a fiber bundle is a device that defines a notion of parallel transport on the bundle; that is, a way to "connect" or identify fibers over nearby points. The most common case is that of a linear connection on a vector bundle, for which the notion of parallel transport must be linear.

Enhanced full rate

Enhanced Full Rate or EFR or GSM-EFR or GSM 06.60 is a speech coding standard that was developed in order to improve the quality of GSM.

Half Rate

Half Rate (HR or GSM-HR or GSM 06.20) is a speech coding system for GSM, developed in the early 1990s.

Since the codec, operating at 5.6 kbit/s, requires half the bandwidth of the Full Rate codec, network capacity for voice traffic is doubled, at the expense of audio quality. The sampling rate is 8 kHz with resolution 13 bit, frame length 160 samples (20 ms) and subframe length 40 samples (5 ms).

GSM Half Rate is specified in ETSI EN 300 969 (GSM 06.20), and uses a form of the VSELP algorithm. Previous specification was in ETSI ETS 300 581–2, which first edition was published in December 1995.

For some Nokia phones one can configure the use of this codec:

To activate HR codec use enter the following code: *4720#
To deactivate HR codec use enter the following code: #4720#
