Mappings from MIS_LINK_SAP to media-specific SAPs

IEEE Std 802.16

C_SAP is defined by IEEE Std 802.16g^TM-2007 [B21] and it includes primitives related to the following:

Handovers [e.g., notification of HO request from mobile station (MS)]

Idle mode mobility management (e.g., Mobile entering idle mode)

Subscriber and session management (e.g., Mobile requesting session setup)

Radio resource management

Authentication, Authorization, and Accounting (AAA) server signaling (e.g., EAP payloads)

Media independent function services

M_SAP is defined by IEEE Std 802.16g-2007 [B21] and it includes primitives related to the following:

System configuration

Monitoring statistics

Notifications triggers

Multi-mode interface management

CS_SAP, defined in the IEEE Std 802.16, provides the interface between the MISF and the service-specific Convergence Sublayer in IEEE 802.16 networks. This SAP is used for the L2 transport of MIS messages through data frames across IEEE 802.16 access links.

Table E. 1 lists this mapping.

3GPP and 3GPP2

3GPP and 3GPP2 service primitives for GERAN, UMTS, long term evolution (LTE), cdma2000, cdma2000-HRPD and UMB are used to access MIS services. This is done by establishing a relationship between the 3GPP/3GPP2 primitives and MIS primitives.

Table E.3 lists this mapping. Note that a 3GPP primitive group can be mapped to more than one MIS primitive, as shown in Table E.3.

Data type definition

General

Basic data types

Data type name	Definition	Binary encoding rule
BITMAP(size)	A bitmap of the specified size. Usually used to represent a list of IDs. Range: Each bit has a value of '0' or '1'.	A BITMAP(N), where N must be a multiple of 8, is made up of an N/8 octet values and encoded in network byte order.
CHOICE( DATATYPE1, DATATYPE2[,... ])	A data type that consists of only one of the data types listed: DATATYPE1,DATATYPE2[,... ].	A one-octet Selector field, followed by a variable length Value field. The Selector value determines the data type. If Selector==i, (i+1)-th data type in the list of data types DATATYPE1,DATATYPE2[,... ] is selected. The Selector value is encoded as UNSIGNED_INT(1). The Value field is encoded using the encoding rule for the selected data type.
INFO_ELEMENT	A binary encoded structure for Informa- tion Elements.	See 6.5.6.
INTEGER(size)	A signed integer of the specified size in number of octets. Range: Each octet has a value of 0x00 to 0xff.	Each octet of an INTEGER(N) value [N=1,2,...] is encoded in network-byte order into an N-octet field. The most significant bit of the first octet is the sign bit. If the sign bit is set, it indicates a negative integer. Otherwise, it indicates a non-negative integer. A negative integer is encoded as 2s complement.
LIST(DATATYPE)	A list of values of DATATYPE	See F.2 for details.
NULL	A data type with empty data.	No octet is encoded for this data type. This data type is used to define an optional data type.

Data type name	Definition	Binary encoding rule
OCTET(size)	An array of octets. The size specifies the length.	The octets are encoded in network byte order.
SEQUENCE( DATATYPE1, DATATYPE2[,...])	A data type that consists of two or more data types.	DATATYPE1,DATATYPE2[,... ] are encoded in the order of appearance. Each data type is encoded using the encoding rule for the data type.
UNSIGNED_INT(size)	An unsigned integer of the specified size in number of octets. Range: Each octet has a value of 0x00 to 0xff.	Each octet of an UNSIGNED_INT(N) value [N=1,2,...] is encoded in network-byte order into an N-octet field.

Case 1: If the number of list elements in the Value field is less than 128, the size of the Length field is always one octet and the MSB of the octet is set to the value ‘0’. The values of the other seven bits of this octet indicate the actual number of list elements in the Value field.

Case 2: If the number of list elements in the Value field is exactly 128, the size of the Length field is one octet. The MSB of the Length octet is set to the value '1' and the other seven bits of this octet are all set to the value ‘0’.

Case 3: If the number of list elements in the Value field is greater than 128, then the Length field is always greater than one octet. The MSB of the first octet of the Length field is set to the value ‘1’ and the remaining seven bits of the first octet indicate the number of octets that are appended further. The number represented by the 2nd and subsequent octets of the Length field, when added to 128, indicates the total number of list elements in the Value field.

For example, an attribute of type LIST(LINK_ID) with two elements is encoded as shown in Figure F. 1 (LINK_ID is defined in F.3.4):
