Hi,

TS 25.433

-- Snip --

9.2.1.63 Transport Layer Address

In case of transport bearer establishment with ALCAP [2][31], this IE contains the address to be used for Transport

Network Control Plane signalling to establish the transport bearer according to [2][31].

In order to allow transport bearer establishment without ALCAP, this IE contains the address of the transport bearer to

be used for the user plane transport.

For details on the Transport Address used see ref. [2][31].

--- End Snip ---

[2}  3GPP TS 25.426: "UTRAN Iur and Iub Interface Data Transport & Transport Signalling for DCH Data Streams".

[31]  3GPP TS 25.434: "UTRAN Iub Interface Data Transport & Transport Signalling for Common Transport Channel Data Streams ".

BIT STRING (1..160, …)

I have not checked the referenced dockuments. But I guess the content depends on the context.

Regards

Anders

Hi List,

I need help to understand how Transportlayeraddress is decoded.TransportLayerAddress is per bit string (20 ocetet) which is decoded as follows:

 

transportLayerAddress 350001 : 10.3.35.131

How ever the 20 octet for transportlayer address is

 

35 00 01 0a 03 23 83 00 00 00 00 00 00 00 00 00 00 00 00 00.

 

I guess its decoded as port number:ip address

 

Can any one give me pointer how ip address can be fetched from transportlayeraddress?

in this case ide decodes it decodes first 3 ocetet as port number or some thing else.?

next 4 ocetet is converted to dotted decimal ip address.

 

can any one give me some pointer where i can find info about composing transportlayeraddress to port number(as i guess) and ip address.

How if there are no octetes after 7 octets having 00 value. i mean if we have transportlayeraddress as 35 00 01 0a 03 23 83 11 22 33 44 55 66 77 88 99 11 22 33 44.

link where u can see the decoding is as folows:

https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=1951

here soem decoding logs are given where transpostlayeraddress is decoded as

transportLayerAddress 350001 : 10.3.35.131
