The Service-Selection attribute (Type value 146) is of type UTF-8
text and contains the name of the service or the external network
with which the mobility service for the particular MN SHOULD be
associated . The identifier MUST be unique within the
PMIPv6 Domain when normalized using the selected normalization form
for the particular PMIPv6 Domain deployment. For instance,
uses the Normalization Form KC (NFKC).
The MAG MUST include the Service-Selection attribute in the Access-
Request sent to the AAA if the information was acquired, e.g., by
operator-specific configuration. The AAA MAY include the Service-
Selection attribute in the Access-Accept response message to the MAG
even if it was not included in the Access-Request as a means of
indicating the MN's default service.
The Service Selection mobility option defined in can be
used in PBU/PBA messages between the MAG and LMA. On the LMA-to-AAA
interface, the LMA MAY populate the Service-Selection attribute in
the Access-Request message using the service information found in the
received PBU, if such a mobility option were included. The Service-
Selection identifier should be used to assist the PBU authorization,
the assignment of the MN-HNP, and the IPv4-MN-HoA as described in
