The different multislot class specification is detailed in the Annex B of the 3GPP Technical Specification 45.002 (Multiplexing and multiple access on the radio path) The network will automatically configure the for either 3+2 or 4+1 operation depending on the nature of data transfer.Įach multislot class identifies the following:- a)the maximum number of Timeslots that can be allocated on uplink b)the maximum number of Timeslots that can be allocated on downlink c)the total number of timeslots which can be allocated by the network to the mobile d) T Ta : the time needed for the mobile phone to perform adjacent cell signal level measurement and get ready to transmit e) T Tb :the time needed for the MS to get ready to transmit f)T Ra : the time needed for the MS to perform adjacent cell signal level measurement and get ready to receive g) T Rb :the time needed for the MS to get ready to receive. However simultaneously a maximum number of 5 simultaneous timeslots can be used in both uplink and downlink. A class 10 mobile uses a maximum of 4 timeslots in downlink direction and 2 timeslots in uplink direction. The first number(5) is the number of downlink timeslots and the second number is the number of uplink timeslots allocated to the mobile station.Ī commonly used multislot class is class 10 for many GPRS/EGPRS mobiles. The network uses the multislot class information for allocating radio channels in the uplink and downlink direction.Ī multislot allocation can be represented for example like 5+2. Multislot class with values greater than 31 are referred to as high multislot classes. The multislot class of a mobile phone can be found out by looking at the technical specifications of the mobile phone. It indirectly determines the speed of data transfer in the Uplink and Downlink direction.Ī multislot class can be a value between 1 to 45.

A multislot class is an important part of a technical specification of a GPRS/ EGPRS enabled mobile phone which primarily indicates the maximum number of radio timeslots that can be allocated to a mobile phone.
