Abstract: Un método y un dispositivo para realizar entrega independiente de media (MIH) en un sistema de comunicacion inalámbrica. El método incluye, y el aparato está configurado para, generar un mensaje de entrega de capa más alta, enviar el mensaje de entrega de capa más alta encapsulado en una comunicacion formateadas de menor nivel, establecer un dispositivo temporizador de capa más alta para un periodo de tiempo finalizado en conexion con el envío del mensaje de entrega encapsulado de capa más alta y el reenvío del mensaje de entrega de capa más alta encapsulado en una comunicacion formateada de menor nivel a menos de que sea recibido un reconocimiento de capa más alta antes de la expiracion del periodo de tiempo finalizado.

Abstract: A method and apparatus for performing a handover are disclosed. An Intern et protocol (IP) multimedia subsystem (IMS) client registers with an IMS net work and establishes a media independent handover (MIH) session with an MIH application server using a session initiation protocol (SIP). The IMS client establishes a session for IP-based service, (e.g., voice over IP (VoIP)), w ith a communication peer using an SIP. MIH messages are exchanged for handov er with the MIH application server over IP. After handover, the session is r esumed. A serving call session control function (S-CSCF) triggers the MIH ap plication server based on a string "MIH services" and a unique identifier in cluded in an INVITE request. The IMS client may send a REFER request to the MIH application server after the handover to resume the session. Alternative ly, the IMS client may send a RE-INVITE request to the MIH application serve r and the communication peer.

Abstract: The present invention modifies existing media independent handover (MIH) function (MIHF) frame format as defined by the IEEE 802.21 standard. In one embodiment, the variable load of the MIHF frame is modified to eliminate the MIHF variable header by defining the MIHF identification (ID) field and the session ID field as fixed fields in the MIHF fixed header. Thus, the MIHF variable load is only made up of the MIHF payload. In another embodiment, a field such as an information element (IE), a header, or MIH service data such as a command or an event, is represented by a type field, a length field and a value field (TLV). The length of the value field is exactly 128 octets, and the length field only occupies one octet.

Abstract: A method and wireless communication system may be used for transferring management information. An access point (AP) may transmit a management information base (MIB) information request including a category field and an action details field to a wireless transmit/receive (WTRU). In response to receiving the information request, the WTRU may determine whether or not to provide management information to the AP. When the WTRU provides management information to the AP, the WTRU may compile management information stored in a MIB located in the WTRU and transmit a MIB information report to the AP. The MIB may list a plurality of tables containing information associated with radio resource management (RRM) and at least one table containing physical layer measurements. The AP may include a MIB for storing MIB information of the WTRU. The AP may transmit the stored MIB information of the WTRU in response to a request.

Abstract: A method for congestion control in the uplink of a wireless communication system having a wireless transmit/receive unit (WTRU) and a radio network controller (RNC) begins by receiving an interference report for each user. The average noise rise for each user calculated and congestion relieving measures are implemented based upon the average noise rise and the WTRU battery level. A method for congestion control in the downlink of a wireless communication system having a WTRU and a RNC begins by receiving a transmission power report for each user. The transmission power for each user is calculated, and congestion relieving measures are implemented based upon the average transmission power and the WTRU battery level.
