Abstract: A method for establishing a connection between a circuit-switched mobile station (MS) and a packet-switched switching element (MSC). A radio network controller (RNC) receives a first initiation signal (an attach request) from the mobile station (MS) via a circuit-switched connection. The RNC opens a signaling connection for the mobile station. While the signaling connection is active, the RNC receives a second initiation signal (call setup) and opens a real-time connection for the mobile station. Thus the packet-switched switching element (MSC) is able to switch a real-time connection to/from the circuit-switched mobile station (MS).

Abstract: In an access network which supports a mobile IP protocol, a mobile station may perform several handovers between access nodes during a long session which may cause inefficient mobile IP routing. In the present invention, an access node, which is the target of a handover during an IP session, is arranged to check the preferred mobility agent in respect of the optimal routing on the mobile IP level, and if a more preferred mobility agent is available and not the same as a current mobility agent, the connection to the current mobility agent is closed, and a new connection to the preferred mobility agent of the respective access node is opened. In merit of the new connection established by the access node to the preferred mobility agent, the agent advertisement messages sent by the new mobility agent can be received by the mobile node, and thereby the mobile node is able to detect the change of the attachment point (i.e. mobility agent) and to initiate standard mobile IP registration.

Abstract: The invention is directed to a communication network wherein a direct tunnel may be formed between a user equipment and a gateway support node, bypassing an intermediate serving support node. If, however, the gateway node should be outside of the actual communication network to which the user equipment is connected, a two-tunnel concept is used wherein a tunnel is provided between the user equipment and the serving support node. Likewise, when receiving a request for Lawful Interception, the tunnel formed between the user equipment and the gateway node is reconfigured to be directed to the serving node for guiding all user traffic and control signaling via this serving node.

Abstract: A communication system can include a network having a first network access point and a second network access point and being capable of carrying data between the first network access point and the second access point via, for example, a packet-switched bearer and a circuit-switched bearer. The communications system can also include a first terminal configured to connect to the first network access point and a second terminal configured to connect to the second network access point. Each terminal can be capable of simultaneously supporting a packet-switched connection and a circuit-switched connection with the other terminal via the network as a single logical communication arrangement.

Abstract: In an access network which supports a mobile IP protocol, a packet data protocol context is opened at support node and a gateway node in order to establish a connection between a mobile node and a mobile IP foreign agent located at the gateway node. A mobile IP registration over the connection is initiated. The gateway node monitors whether the registration is successful or fails. The PDP context is deleted, if the registration irrecoverably fails. If the registration was unsuccessful but a retry could be successful, the PDP context may not deleted, but the registration is retried.

Abstract: The present invention relates to a method, a network device (2), and a terminal device (1) for controlling the activation of packet data protocol context in a network supporting packet switched transmission of data units. A push information element HSS Push IE is added to a data base (4?) containing information to control push services. This push information element Push IE is sent to a network device (2) with a support node functionality. This push information element is evaluated. Thus, network requested context activation procedures is controlled to thereby reduce the number of unnecessary context activations.

Abstract: The invention is directed to enabling an serving node and a gateway node to be informed of a new route for a new node or sub-network that has become active behind a Mobile Terminal that can also act as a router. When IP level route injection occurs at the Mobile Terminal, a Modify session profile message causes insertion of a new IP address or prefix at a gateway node related to the new route. Also, the gateway node will update the serving node and the Mobile Terminal with information related to the new route or a proposed new route. The Mobile Terminal and the gateway node can share routing information over a dynamic routing protocol. Additionally, the Mobile Terminal and the gateway node can configure static routing information on routes towards each other. The new route can be added with 24.008 and/or GTP messages when initiated on the Mobile Terminal side for either the dynamic or static case.

Abstract: The invention proposes a communication method and network having at least two network entities adapted to receive and/or transmit call-related information when handling a call connection, wherein at least one of the network entities is adapted to send load-related information regarding the load or condition of itself or of another network entity to a further network entity. The further network entity preferably contains a memory means for storing said load-related information. A load-information request message may be sent to another network entity as a separate message, or as part of another message. The response message returned from the addressed network entity may be returned as a separate message, or as part of another message. The network preferably is a packet-switched network, preferably a GPRS or UMTS network.

Abstract: In an access network which supports macro mobility management, an access node checks during an attach procedure of a mobile station whether the mobile has macro mobility capability, i.e., whether there is a potential need for a macro mobility services. If there is no macro mobility capability, a normal attach procedure is preformed. However, if there is macro mobility capability, the access node selects a suitable mobility entity to the mobile station, sends the identity of the selected mobility entity to the mobile station and requests the initiation of a packet protocol context activation in the system.

Abstract: In a GPRS system, a method of a mobile station acquiring an IP network address. The method comprises the steps of: the mobile station generating a link identifier and sending it to a gateway over a wireless link in a network address request together with a request to check if the link identifier is unique; the gateway receiving the network address request and checking if the link identifier is unique; the gateway responding with a network address request response including either the sending a unique link identifier confirmed as being unique or a different unique link identifier; the gateway sending a network prefix to the mobile station; the mobile station combining the interface identifier and the network prefix to generate the IP network address.

Abstract: A method for a mobile station to acquire a IP network address from a gateway in GPRS system. First the mobile station generates a link identifier. Next the mobile requests a network address by sending a link identifier over a wireless to a gateway along with a request for the gateway to check to see if the link identifier is unique. Upon receiving the network address request the gateway checks to see if the link identifier is unique. The gateway responses by either confirming that the network link identifier is unique or by sending a different unique link identifier to the mobile station. The gateway also has the ability to respond by sending a network prefix to the mobile station. Upon receiving the network prefix the mobile station combines the network prefix with the interface identifier to generate a IP network address.
