-- ===================================

-- Common Parameters

-- ===================================

Location ::= SEQUENCE

	-- This is a common parameter, the use of this parameter is described in clause 4.5

{

	umtsHI2Location			[0] UmtsHI2Operations.Location OPTIONAL,

	epsLocation				[1] EpsHI2Operations.EPSLocation OPTIONAL,

	...,

	wlanLocationAttributes	[2] WlanLocationAttributes OPTIONAL,

	eTSI671HI2Location		[3] HI2Operations.Location OPTIONAL

}

WlanLocationAttributes ::= SEQUENCE

{

	wlanAPMACAddress 		[0] OCTET STRING (SIZE(6)) OPTIONAL,

		-- 48-bit (6 octet) MAC address of the WLAN access point derived from the BSSID

	...

} 

IPAddress ::= SEQUENCE

	-- This parameter was previously imported from ETSI TS 101 671 [4] but has been copied

    -- to ETSI TS 102 232-1 (the present document). It is not recommended to use this parameter in 

    -- future change requests. Suggested approach is to use a parameter from ETSI TS 103 280 [44]

    -- instead.

{

	iP-type				[1] ENUMERATED

	{

		iPV4(0),

		iPV6(1),

		...

	},

	iP-value			[2] IP-value,

	iP-assignment		[3] ENUMERATED

	{

		static(1),

			-- The static coding shall be used to report a static address.

		dynamic(2),

			-- The dynamic coding shall be used to report a dynamically allocated address.

		notKnown(3),

			-- The notKnown coding shall be used to report other than static or dynamically

			-- allocated IP addresses.

		...

	} OPTIONAL,

	...,

	iPv6PrefixLength	[4] INTEGER (1..128) OPTIONAL,

		-- Indicates the length of the prefix delegated by the CSP to the subscriber

		-- example: 60 if IP address is "2001:db8:0:85a3::ac1f:8001/60"

		-- Mandatory in case where the iP-value contains an IPv6 binary value

	iPv4SubnetMask		[5] OCTET STRING (SIZE(4)) OPTIONAL

		-- For IPv4 addresses, this indicates the subnet mask to be applied to the iP-value field.

		-- The subnet mask is intended to be presented as a binary value, e.g. "ff ff ff f8" to

		-- represent the dotted-decimal subnet mask of "255.255.255.248" corresponding to

		-- a /29 CIDR-format subnet mask

}

IP-value ::= CHOICE

{

	iPBinaryAddress	[1] OCTET STRING (SIZE(4..16)),

		-- In case of IPv6, the Prefix Length is provided by the "iPv6PrefixLength"

		-- In case of IPv4, the netmask is provided by the "iPv4SubnetMask"

	iPTextAddress	[2] IA5String (SIZE(7..45)),

		-- In case of IPv6, the delivered iPTextAddress field could include a complete

		-- single IPv6-Address or an IPv6-Prefix for a subnetwork on the target side.

		-- In case of IPv4, the delivered iPTextAddress field could include a single

		-- IPv4 address or an IPv4address/netmask, for example "192.168.1.1" or "192.168.1.1/24"

	...

}

LawfulInterceptionIdentifier ::= LIID

	-- LIID is a common parameter imported from ETSI TS 103 280 [44].

	-- It is redefined as LawfulInterceptionIdentifier in this

	-- module to preserve the original type name during the

	-- removal of imports from ETSI TS 101 671 [4].
