摘要:
The present invention relates to methods and arrangements in mobile radio telecommunications for enabling access to Circuit Switched (CS) services for a user equipment (UE) that is connected to a LTE/SAE (Long Term Evolution/System Architecture Evolution) network. The UE's current position is stored in a LTE position format in the LTE network or in the SAE network. The invention provides steps and means for transforming the UE's position in LTE format to position information in CS format for the UE, steps and means for registering the UE in the CS network using said transformed position information, and steps and means for establishing access to CS services provided by said CS network.

A method of setting up a session between a client terminal and a media supply system in order to transport a unicast media stream from the media supply system to the client terminal over an intervening IP network, the media supply system implementing the Real Time Streaming Protocol. The method comprises conducting a negotiation between the client terminal and the media supply system over an IP Multimedia Subsystem network in order to identify to the IP Multimedia Subsystem network the source and destination IP addresses and port numbers for the media stream, and subsequently sending Real Time Streaming Protocol messages from the client terminal to the media supply system in order to control the playout of media from the media supply system.

A method and apparatus are provided for handling a paging request for a Circuit Switched session, when the paging request is intended for a terminal attached to a Packet Switched cell in a radio access network and having one or more ongoing Packet Switched sessions. The request is received at a node in the radio access or core network to establish a Circuit Switched session with the terminal whilst the terminal has one or more ongoing Packet Switched sessions. The importance of the ongoing Packet Switched session is determined at the node, and the paging request is rejected if any of the ongoing Packet Switched sessions is more important than the Circuit Switched session. The node may be a MME, an eNodeB or the terminal itself.

The combination of narrowband applications with broadband transport is enabled by combining a first node having narrowband ability with a second node having broadband ability in which call control functionality of the first node is provided to the second node. Both the first node and the second node have connection control functionality for switching data information of a given call. However, the broadband second node receives signaling information from the narrowband first node, which has call control functionality, over one or more links to enable the second node to switch a call in accordance with determined call control instructions. The combination of the narrowband first node and the broadband second node results in a hybrid switch that is capable of operating with both synchronous transfer mode (STM) networks and asynchronous transfer mode (ATM) networks.
