Service continuity is provided between a 3GPP network and a non-3GPP network. When a mobile station having accepted service in the 3GPP network moves to the non-3GPP network or returns from the non-3GPP network to the 3GPP network, an interworking gateway is interworked with a GGSN through a universal tunnel using a packet data network, and accordingly a mobile subscriber may accept seamless service.
摘要:
A 3GPP-WLAN interworking system to which WLAN user equipment is accessed includes a WLAN access network including a WLAN access point, a 3GPP packet-switched service network including terminal equipment, a 3GPP core network connecting the WLAN access network and the 3GPP packet-switched service network, and a packet data gateway relaying the 3GPP core network and the 3GPP packet-switched service network. The WLAN user equipment negotiates a QoS according to a wireless environment with the WLAN access point to generate a WLAN bearer, negotiates a QoS according to a type of user data with the packet data gateway to generate a WLAN 3GPP IP access bearer, and negotiates a QoS according to data process performance of the terminal equipment with the terminal equipment to generate an end-to-end bearer.
摘要:
The present invention discloses a gateway and a terminal negotiating a QoS in a network interworking system. The terminal negotiates a QoS with a WLAN access point and establishes a WLAN access bearer. In addition, the terminal negotiates a QoS with the gateway for packet exchange through the WLAN access bearer. The gateway accepts a QoS according to a QoS of an external bearer, and the terminal and the gateway establish an I-WLAN bearer. Subsequently, the terminal negotiates a QoS with the gateway for packet exchange with an end terminal through the I-WLAN bearer. The gateway accepts the QoS depending on available resources of the external and I-WLAN bearers, and the terminal and the gateway establish an IP bearer.

The present invention relates to a method for guaranteeing service continuity between a 3GPP network and a non-3GPP network. According to the exemplary embodiment of the present invention, when a mobile station receiving a service from the 3GPP network moves to the non-3GPP network or it moves back to the 3GPP network from the non-3GPP network, an inter-working gateway inter-works with a SGSN or a GGSN through the 3GPP network to provide a seamless service to a mobile subscriber.

Provided is a method for controlling an MBMS bearer of a mobile terminal. The method includes the steps of: at the RRC, establishing an MBMS bearer for an MBMS service when the RRC is informed of MBMS service session start from outside; at the RRC, informing the RABM of MBMS service session start when the MBMS bearer is established; and receiving MBMS service data from outside through the established MBMS bearer if the RABM transits a session inactive state to a session active state.

The present invention relates to a multi-mode communication system and a method thereof. The multi-mode communication system uses a first mode among a plurality communication modes for accessing a first mobility control entity (MCE) among a plurality of MCEs, and communicates data with the first MCE. The multi-mode communication system receives a paging request that has been transmitted from a multi-mode control entity (MMCE) for accessing a second MCE from the first MCE and analyzes the paging request, and puts the first mode into a sleep mode and a second mode for accessing the second MCE into an awake mode based on the analysis. Subsequently, multi-mode UE accesses the second MCE by using the second mode in the awake mode. According to the present invention, an MMCE for multi-mode control is provided to integrate and manage an idle state for each access mode of multi-mode user equipment, thereby minimizing power consumption due to access of the multi-mode UE to a radio access system. In addition, a change of the access of the multi-mode UE to the radio access system due to a paging request can be efficiently performed.

A method for controlling uplink IP packet filtering in a mobile terminal in a 3GPP Evolved Packet System (EPS) is provided, including an information receiving operation of receiving IP address information allocated to user equipment, and filtering information required for delivering an uplink IP packet received from the user equipment; and a filtering operation for determining which packet data network and a bearer the IP packet is delivered to, based on the IP address information and the filtering information. In a 3GPP evolved packet system supporting a default bearer function, a packet data network to which an uplink IP packet is delivered and a bearer identifier can be efficiently determined when the user equipment simultaneously accesses one or more packet data networks and is allocated several IP addresses, resulting in effective uplink packet filtering.

The present invention relates to a multi-media broadcast and multicast service (MBMS) providing system and a method thereof. The MBMS providing system provides an MBMS to a terminal having an MBMS function. The MBMS providing system includes a service center and a radio access network. The service center provides MBMS data and metadata having service announcement information abut the MBMS to the terminal. The radio access network periodically transmits establishment information for receiving the metadata to the terminal, and provides the metadata and the MBMS data received from the service center to the terminal through nodes for transmitting data. The establishment information includes first establishment information having a service identifier and IP/UDP parameters for receiving the metadata, and second establishment information for establishing a radio channel.
