The present document specifies the eneral structure of layer 3 and traffic manaement procedures and messaes usedon the ;bis interface to support sinallin procedures as defined in 3GPP T! *9.++> and 3GPP T! 99.+,>. !upport for

5ocation !ervices (51!) related sinallin- as defined in 3GPP T! *3.+=,- is also included. 3GPP T! *3.+=, identifiesnew ;bis sinallin to support 0T!;embedded Type 0 5Ms as well as standalone- Type 0 5Ms. The standaloneType 0 5M supports the layer , and * sinallin for the ;bis as well as the 5ocation !ervice messae defined in thepresent document.

The use and eneral aspects of the 0ase !tation 1ontroller (0!1) to 0ase !tation Transceiver (0T!) interface (the ;bis

interface) are iven in 3GPP T! 9>.+:,.

&etwor" manaement procedures and messaes for the ;bis interface are defined in 3GPP T! +>.:?.

The functional split between 0!1 and 0T! is defined in 3GPP T! 9>.+:*. The procedures and messaes re8uired to

support this split are defined in detail in the present document.

1.1 Reere&"eThe followin documents contain provisions which- throuh reference in this te't- constitute provisions of the presentdocument.

non;specific.

7or a non;specific reference- the latest version applies. %n the case of a reference to a 3GPP document (includin

a G!M document)- a non;specific reference implicitly refers to the latest version of that document in the sameRelease as the present document.

7or the purposes of the present document- the abbreviations defined in 3GPP T/ *,.?+: apply.

model for 53 can be found in fiure *.,.

5* addressin is made to T/D (or 017) usin the T2% of 5P@. @ifferent 5* lin"s are used for traffic manaementmessaes (/!5- /adio !inallin 5in")- networ" manaement messaes (OM5- Operation Maintenance 5in") and5* manaement messaes (5*M5- 5ayer * Manaement 5in").

7or traffic manaement- two types of sinallin messaes have been defined

Tran#&arent Me##a!e#:Messaes which are forwarded by 0T! without interpretation or chanes.

Non'Tran#&arent Me##a!e#:Messaes which are sent only between 0!1 and 0T! and which 0T! is actin upon or

which are the results of 0T! actions.

%n addition- the messaes have been rouped into four main roups /adio 5in" 5ayer Manaement- @edicated 1hannelManaement- 1ommon 1hannel Manaement and T/D Manaement messaes.

@iscrimination between these types and roups is based on the Messae @iscriminator which is sent as the first octet in

all messaes. Transparent and non;transparent messaes are discriminated by a transparency fla (T;bit) in the Messae@iscriminator. Transparent messaes are merely forwarded to 5* on the radio interface.

%n order to address the relevant radio channel- a 1hannel &umber element is included to support the distribution ofmessaes to relevant physical channels on the T/D. 5in" %dentifier element supports the distribution on loical

lin"sNchannels on the radio interface (compare the @51% element of the interface- 3GPP T! 9>.++

This sub;clause describes procedures related to the manaement of a lin" layer connection on the radio path.

3.1 !i&7 eta'li$e&t i&di"atio&

This procedure is used by 0T! to indicate to 0!1 that a layer * lin" on the radio path has been established in multi;frame mode at the initiative of an M!. 0!1 can use this indication to set up an !11P connection to M!1.

pon reception of a !0M frame on a lin" on an active channel- the 0T! sends an 2!Tablish %&@ication messae to0!1. The messae contains the contents of the information field of the !0M frame if present.

The procedure is used in all establishment cases- for all channels and all !P%s.

The procedure is started by 0!1 sendin an 2!Tablish /2Euest messae to 0T!. 0T! then establishes the lin" bysendin an !0M frame. pon reception of the ac"nowledement (;frame) from M!- 0T! sends an 2!Tablish1O&7irm messae to 0!1.

This procedure is used by 0!1 to re8uest the sendin of a 53 messae to M! in ac"nowleded mode.

0!1 sends a @T /2Euest messae to 0T!. The messae contains the complete 53 messae to be sent in

%f the T/D for some reason cannot activate the resource as re8uested by the 1A&nel ctivation messae- the T/Dshall return a 1A&nel 1T%Fation &eative 1$nowlede messae with the most appropriate cause value.

Possible cause values may be

; OM intervention (e.. channel bloc"ed)H

; resource not available (e.. speech coder- encryption device)H

; e8uipment failureH

; etc.

%n the handover case- the procedure is initiated by the taret 0!1 when this receives the A&@Over /2Euest messaefrom M!1 (or autonomously by 0!1 for 0!1 internal handover). The 0!1 sends a 1A&nel 1T%Fation messae tothe relevant T/D. The messae contains the Aandover /eference value which can be used by the 0T! to chec" theAandover ccess from M!. fter activation of the channel T/D responds with a 1A&nel 1T%Fation 1$nowledemessae containin the current frame number at 0T!.

The 0!1 can then determine the !tartin Time parameter to be included in the A&@Over /2Euest 1$nowledemessae to M!1 (and the A&@Over 1oMman@ messae to M!).

6.3 lo "o&trol

This procedure is defined to ive some deree of flow control. %t can be used for T/D processor overload- downlin"

111A overload and 11A overload.

The alorithm used in 0!1 to control the traffic flow is as follows

pon receipt of the first OF2/5O@ messae- 0!1 reduces the traffic by one step and starts timers T, and T*. @urinT, all OF2/5O@ messaes are inored in order not to reduce the traffic too rapidly. /eception of an OF2/5O@messae after T, but still durin T* will decrease the traffic by one more step and timers T, and T* are restarted. Thisstep by step reduction of traffic is continued until ma'imum reduction is obtained.

%f T* e'pires (i.e. no OF2/5O@ messae was received durin T*)- the traffic will be increased by one step and T*restarted. This step by step increase of traffic will be continued until full load has been resumed.

The number of steps and the method of reducin the load is considered to be implementation dependent. 7or e'ample-the amount of random accesses and thereby access rants can be reduced by use of the /1A 1ontrol parameters (e..ccess 1ontrol 1lass or 1ell 0arred) or the 1ell !election parameters (e.. 1255;/2!2521T;AB!T2/2!%! or/D52F; 112!!;M%&) in the system information messaes of 3GPP T! 99.+,>.

The 2P1 mode field (octet *) indicates whether the activated channel shall be in enhanced power control (2P1) mode.

%t is only valid for channels on which 2P1 may be used. %t is coded as follows

Falue

+ 1hannel not in 2P1 mode

, 1hannel in 2P1 mode

&OT2 The 2P1 mode field is only valid in the 1A&&25 1T%FT%O& messae.

The 7P1V2P1 (7ast Power 1ontrolN2nhanced Power 1ontrol) field (octet *) has different interpretation dependin on

the channel mode of the channel and whether the channel is in 2P1 mode.

%f the channel mode is such that 7P1 may be used- the 7P1V2P1 field indicates whether 7ast Measurement /eportinand Power 1ontrol mechanism is used. %t is coded as follows

Falue

+ 7ast Power 1ontrol not in use

, 7ast Power 1ontrol in use

%f the channel is in 2P1 mode- the 7P1V2P1 field indicates whether 2P1 procedures are used for 0! (downlin") power

control. %t is coded as follows

Falue

+ 2P1 not in use for 0! power control

, 2P1 in use for 0! power control

%f the channel mode is such that 7P1 may not be used and the channel is not in 2P1 mode- the 0T! shall inore the

value of the 7P1V2P1 field and the 0!1 shall set its value to +.

The Power 5evel field (octet *) indicates the number of * d0 steps by which the power shall be reduced from itsnominal value- Pn- set by the networ" operator to adjust the coverae. Thus the Power 5evel values correspond to thefollowin powers (relative to Pn)
