## Title
Method and apparatus for mapping 3GPP service primitives to media independent handover event services

## Abstract

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.

FIELD OF INVENTION
The present invention relates to wireless communication systems. More particularly, the present invention relates to mapping of Third Generation Partnership Project (3GPP) service primitives to media independent handover (MIH) event services as defined within the IEEE 802.21 standard.
BACKGROUND
The IEEE 802.21 standard relates to mechanisms and procedures that aid in the execution and management of inter-system handovers. Under the IEEE 802.21 standard, three main services can be accessed by mobility management (MM) applications in order to aid in the management of handover operations and system discovery and system selection. These three services include an event service, an information service and a command service, which are delivered to prospective users using a common uniform interface, regardless of the underlying access technologies supporting the communication towards the core network.
A method which supports the delivery of event services is needed to determine when an event is to be triggered based on the prevailing characteristics of the underlying technology. The underlying technology could be supported by the 3GPP specification, 3GPP2 and wireless local area networks (WLANs), (e.g., IEEE 802.11 or IEEE 802.16), and the like.
Currently, there are no procedures or functionality to generate triggers toward upper layers, based on information provided by the 3GPP underlying layers. The IEEE 802.21 specification outlines triggers that should be sent to upper layers. However, the IEEE 802.21 specification does not describe how events are triggered when the underlying physical resources are based on 3GPP technology. Therefore a method capable generating these triggers is required.
SUMMARY
The present invention is related to a 3GPP-MIH service access point (SAP) which 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.
The present invention uses existing service primitives already defined within 3GPP in order to trigger events that can be used for the determination of handover operations. These service primitives are mapped onto concrete IEEE 802.21 events as defined in IEEE 802.21, as a means to optimize inter-system handover operations.
The present invention provides a method to trigger MIH events, using existing 3GPP radio resource management (RRM), MM and session management (SM) service primitives. The concept of service primitives mapping is extended using mobility management procedures and concepts introduced within both long term evolution (LTE) and system architecture evolution (SAE) within the 3GPP specifications.
The present invention may be applicable to IEEE 802 standards including WLAN baseline air interface standards such as IEEE 802.11 baseline, IEEE 802.11a orthogonal frequency division multiplex (OFDM) 5 GHz WLAN, IEEE 802.11b high rate direct sequence spread spectrum (HR-DSSS) 2.4 GHz WLAN, IEEE 802.11g OFDM 2.4 GHz WLAN, IEEE 802.11j OFDM 10 MHz option WLAN, IEEE 802.11n high-throughput WLAN, and IEEE 802.16 broadband wireless access systems. The WLAN standards supplement to extend operation for particular scenarios such as IEEE 802.21 MIH.
The present invention is also applicable to cellular standards, such as 3GPP or 3GPP2, and other standardized or proprietary wireless technologies similar to IEEE 802 WLANs, examples notably include 802.15 Bluetooth, and HIPERLAN/2.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention is based on the use existing and new, (e.g., LTE and SAE), primitives within 3GPP that can be mapped onto IEEE 802.21 events as defined by the IEEE 802.21 specification.
A primitive is an abstract representation of functions such as an information function, an event or a command.
An MIH event service classifies, filters and reports changes within the link layer characteristics, (i.e., maximum offered throughput, supported bandwidth, or the like), the link status, (i.e., an indicator of whether the link is operational or not), and the link quality, (e.g., low signal strength). Event services may also indicate changes in the state and transmission behavior of the physical, data link and logical link layers. Furthermore, event services are used to indicate an operation state as a result of a management action.
FIG. 1 is a mapping model for 3GPP layer primitives, where a 3GPP-MIH service access point (SAP) 100 maps 3GPP service primitives to MIH event services according to IEEE 802.xx standards.
As shown in FIG. 1, a radio resources (RR) layer 105, an LLC layer 110, a general packet radio service (GPRS) mobility management (GMM) layer 115, and a session management (SM) layer 120 associated with a global system for mobile communications (GSM)/enhanced data rates for GSM evolution (EDGE) radio access network (GERAN) 125 send 3GPP service primitives 160 to the 3GPP-MIH SAP 100. Furthermore, the non-access stratum (NAS) 130 and the access stratum (AS) 135 of a universal mobile telecommunications system (UMTS) services 140 send 3GPP service primitives 160 to the SAP 100. An LTE system 145 sends 3GPP service primitives 160 via an evolved universal terrestrial radio access (E-UTRA) and evolved core network (E-CORE) layers 155 to the SAP 100. The SAP outputs MIH event services 170 in response to receiving the 3GPP service primitives 160.
FIG. 2 is an exemplary block diagram of the 3GPP-MIH SAP 100 of FIG. 1. The 3GPP-MIH SAP 100 includes a processor 205 and a 3GPP to MIH mapping database 210. When the SAP 100 receives a 3GPP service primitive 160, the processor 205 in the SAP 100 interprets, (i.e., identifies), the 3GPP service primitive 160 in terms of functional capabilities and potential parameters. The processor 205 then queries the mapping database 210 based on such functional capabilities and parameters to obtain and output the MIH event services 170.
Table 1 identifies specific 3GPP service primitives for each of the layers of the GERAN 125 shown in FIG. 1. According to the present invention, the 3GPP service primitives generated by the GERAN 125 via the RR layer 105, the LLC layer 110, the GMM layer 115 and the SM layer 120 are mapped to MIH event services, (e.g., IEEE 802.21 events), as shown in Table 1 below.
