Method and apparatus for mapping 3GPP service primitives to media independent handover event services
A Third Generation Partnership Project (3GPP) media independent handover (MIH) service access point (SAP) is configured to provide MIH event services, (e.g., IEEE 802.21 event services), by mapping service primitives to the MIH event services. The service primitives may be 3GPP service primitives which originate from at least one of a radio resources (RR) layer, a logical link control (LLC) layer, a general packet radio service (GPRS) mobility management (GMM) layer, a session management (SM) layer, a non-access stratum (NAS), an access stratum (AS) and an evolved universal terrestrial radio access (E-UTRA)/evolved core network (E-CORE) system. The event services may include a link parameter change event service, a link up event service, a link going down event service, a link down event service, a handover complete event service and a link detected event service.
