The present invention relates to a method for installing a pipe (313) when drilling a first hole with the aid of a rock drilling apparatus (100), wherein a tool (309) which can be connected to a drilling machine (306) via one or more drill rods (308) is used in said drilling, which method comprises—drilling a first part of said first hole,—installing a pipe (313) in at least a part or said first drilled part of said first hole, wherein the method further comprises:—installing said pipe (313) in said first hole while drilling of said first part of said first hole is in progress.—pulling said drill rod (308) out of said first hole before finishing drilling of said first hole to the desired, compared with said first part, deeper depth. The invention also relates to a system and to a rock drilling apparatus.

The invention relates to a method for handing over a call of a mobile entity that is circuit switched attached via a Mobile Switching Center MSC (120) to an IP Multimedia Subsystem IMS, wherein the mobile entity (100) is registered at the IMS. According to the invention, either the MSC or a media gateway act as application function towards a PCRF with the correct IP address of the media gateway.

The invention provides an increase in the radio coverage area (10) of a base transceiver station (100) having access to multiple transceivers (102, 104, 106, 108) by dedicating at least one of the transceivers (102) for BCCH data. This BCCH transceiver (102) is connected to an antenna arrangement (120) 5 comprising at least two antenna elements (121, 123; 125, 127). Increased BCCH radio coverage (30) is achieved by providing antenna hopping among the at least two antenna elements (121, 123; 125, 127) for the BCCH. Correspondingly, increased TCH coverage (20) is achieved by providing frequency hopping among at least two carrier frequencies for the TCH. The 10 coverage (10) of the base transceiver station (100) is defined as the intersection of the BCCH radio coverage (30) and the TCH coverage (20).

A method for a call control node (MSC Server) enhanced for Single Radio Voice Call Continuity (SRVCC) allowing for a session transfer of a call involving a User Equipment (UE) of a handover party from a circuit switched (CS) access towards a target packet switched (PS) access is provided, the call involving said handover party and another party, said call being anchored in an Service Centralization and Continuity Application Server (SCC AS) of the IP-Multimedia-Subsystem (IMS), the method comprising the steps of receiving (202) an indication that the User Equipment (UE) is SRVCC capable, receiving (204) an indication of an address and port the UE is going to use for speech media over PS, providing (206) the UE with an indication of the address and port to be used towards the other party (remote end), deciding (208) to perform a SRVCC from CS access to said target PS access, sending (210) a relocation request for a bearer to a respective mobility management node (SGSN/MME), including said address and said port of the UE to be used for creating a PDP context, and sending (212) a handover command message to the UE, sending (214) a request for a “Forward Session Transfer” to the SCC AS, using the address and the allocated port to be used for media to construct a respective SDP.
摘要:
For transmitting data between a node (100) of a mobile network and a further node (200), the further node sends downlink data packets to the node (100) of the mobile network. The downlink data packets carry a destination address corresponding to a user equipment (10) connected to the mobile network. For implementing an inband data channel between the node (100) of the mobile network and the further node (200), the further node (200) inserts data destined to the node (100) of the mobile network into at least one of the downlink data packets and marks this downlink data packet as including data destined to the node (100) of the mobile network. The node (100) of the mobile network receives the downlink data packets from the further node (200) and identities, on the basis of the marking, the least one downlink data packet including data destined to the node (100) of the mobile network. The node (100) of the mobile network then extracts the data from the identified downlink data packet. A corresponding inband data channel may also be used in the uplink direction.

According to a first aspect of the present invention there is provided a method of operating a mobility management node to provide location and/or status information for a user terminal connected to an Evolved Packet Core network. The method comprises receiving a request for location and/or status information for the user terminal from a subscriber register, determining the location and/or status information for the user terminal, and sending a response to the subscriber register including the determined location and/or status information.
摘要:
A method and apparatus for providing location information for subscribers connected to a packet-switched mobile access network in connection with emergency calls made over a multimedia service network. An emergency request is received at the multimedia service network from a subscriber containing the calling number of the subscriber. In response thereto, a media gateway control function in the multimedia service network sends a location query including the calling number to a mobile positioning center in the mobile access network, which then can retrieve location information for the subscriber. After receiving location information from the mobile positioning center, the media gateway control function selects an emergency center and sends a location indication for the subscriber thereto in a circuit-switched control message for initiating an emergency call, according to prevailing standards.
