Abstract:
Un procedimiento (400) para acoplar servicios en un primer dominio (13) con servicios en un segundo dominio(14), comprendiendo el procedimiento: recibir (401), en un primer componente de interfaz (31), una notificación de una llamada de un primer tipodesde un primer dispositivo (11) a un segundo dispositivo (12) en el primer dominio (13); y recibir (407), en un segundo componente de interfaz (32), una notificación de inicio de una llamada de unsegundo tipo desde el segundo dispositivo (12) al primer dispositivo (11) en el segundo dominio (14),caracterizado porque el procedimiento (400) comprende además: crear (404), en una componente de creación de contexto (36), un contexto de llamada para elprimer tipo de llamada, donde el contexto de llamada comprende una referencia de llamada para elprimer tipo de llamada y un identificador para el primer dispositivo (11), y utilizar (409), en un componente de notificación (37), el contexto de llamada para notificar al primerdispositivo (11) el inicio de la llamada del segundo tipo desde el segundo dispositivo (12) al primerdispositivo (11).
Abstract:
A system and method in which a notification is received of a call from a first device to a second device in a first domain. A context is created for the first type of call. A notification is received of initiation of a call from the second device to the first device in a second domain. The call context is utilized to notify the first device of the initiation of the call from the second device to the first device.
Abstract:
A pre-registration phase (800) and a resource preparation phase (900) reduce latency when a user equipment (UE) (210) hands over from a non-3GPP radio access (220) such as WiMAX to an 3GPP radio access network (230) such as E--UTRAN. During a pre-registration phase (800), a Forward Attachment Function (260) receives a pre-attach request message (833) and creates (860) a 3GPP mobility management context for the UE (210) that is valid for E-UTRAN access. During a resource preparation phase (900), the mobility management context is transferred to a mobility management entity (MME) (240) and radio and transport resources are reserved for the UE (210) at the target E-UTRAN cell (230). When a handover is initiated (910) by ei-ther the UE or the non-3GPP network, the time-consuming authentication and authorization procedures that are performed during the process of pre- registration can be skipped. Additionally, radio and transport resources have already been assigned to the UE and thus do not have to be set-up when the handover executes.

Abstract:
In order to facilitate a handoff between a legacy circuit switched network (110) and a packet data network (120) such as a 3GPP LTE, 3GPP2 UMB, or WiMAX network, which communication session is anchored in an IMS Voice Call Continuity Application Server (VCC AS) (158), a Circuit Switched Proxy (CS Proxy) (132) is provided in the packet data network that communicates with a Mobile Switching Center (MSC) (118) of the circuit switched network. The CS Proxy allows the packet data network to communicate with the VCC AS, the MSC to communicate with the packet data network, and the MSC to communicate with the VCC AS via the packet data network, thereby allowing an exchange of handoff-related information between the packet data network and the VCC AS, the packet data network and the circuit switched network, and the circuit switched network and the VCC AS via the packet data network.
