  • Publication number: 20090310581
    Abstract: An apparatus, system, and method may include a user device, an HRPD network comprising a HSGW, and a 3GPP EPC network comprising at least one gateway. The user device may be configured to detect a need to establish a connection with the 3GPP EPC network, determine an APN value that corresponds to the 3GPP EPC network, include the APN value in a connection request, and communicate the connection request to an HRPD gateway of the HRPD network. The HRPD gateway may be configured to receive the connection request from the user device, determine a PDN gateway of the 3GPP EPC network that corresponds to the APN value in the connection request, and enable a connection between the user device and the 3GPP EPC network.

  • Patent number: 7290063
    Abstract: A method of relocating the header compression context in a packet network which transmits packets having compressed headers. A connection is established between a mobile terminal and a first network entity and context information used with compression and decompression of the headers of the packets is stored at the mobile terminal and the first network entity. The context information updating is stopped in the mobile terminal and in the first network entity and after that, a snapshot of the compression and decompression context information is taken and stored in the first network entity. The connection between the first network entity and the mobile terminal is changed to a connection between the mobile terminal and a second network entity. The context information snapshot stored by the first network entity is transferred to the second network entity to be stored therein as the context information of the second network entity.

  • Patent number: 7215958
    Abstract: The present invention relates to a relocation method, system and network element for changing a serving radio resource control entity After an initial operating state in which a user equipment (30) has radio links with a serving network element (20) and a drift network element (21) supporting said serving network element (20) with a wireless connection, the serving network element (20) transmits a relocation-specific information to a target network element (22). Based on the relocation-specific information, the target network element (22) establishes a link to the drift network element (21), such that the drift network element (21) can receive user traffic from both the serving network element (20) and the target network element (20). Then, the radio resource control is relocated to the target network element (20). The relocation-specific information may comprise an identifier or a list of identifiers of drift network elements.

  • Patent number: 6895439
    Abstract: The present invention is a system and method which provides authentication for data services for at least one UE (12) using common authentication information based upon information stored in a HSS (16) of a home network (20) of the at least one UE for multiple protocols. At least one proxy server (18) stores authentication information for each of the protocols which may be used to provide data services to the at least one UE. Authentication of the protocols available to the least one UE uses the authentication information stored at the at least one proxy server obtained from the protocol used in the home network of the at least one UE.

  • Publication number: 20040085925
    Abstract: The invention relates to a method and system for managing a connection of a mobile element to a network, the mobile element having at least one user plane connection for transmitting user traffic from and/or to the mobile element, and at least one control plane connection for signaling connection of the mobile element to a radio access network. When a relocation of the connection(s) of the mobile element is to be performed, only the user plane connection(s) is relocated, and the control plane connection(s) is maintained unchanged. The connections are Iu interface connections, i.e. the control plane is to an Iu control plane of a radio access controlling means, and the user plane is an Iu user plane of the radio access controlling means.

  • Patent number: 6721566
    Abstract: The present invention relates to a method and arrangement for performing a cell update procedure in a cellular communications system. The cellular communication system comprises a plurality of cells, and a first and a second network controllers. A station is initially on a first cell controlled by the first controller and then in a second cell controlled by the second controller. When changing from one cell to another the station sends cell update information and other information to the second controller which then stores the received other information and send to the first controller a message indicating that information has been received at the second controller from the station. A network element for use in the above method is also disclosed.
