摘要： A method for duplex telecommunication connection in radio connections is based on a frame-structured interactive communication and a radio system where the frame-structured interactive communication is performed in the radio connections. A means is provided for improving the use of channel resources in implementation of interactive telecommunication connection by providing an FDD connection with one or more TDD dimensions. A full-duplex frequency band is time-duplexed into two or more sub-bands in which interactive communication takes place substantially independently. Transmissions in different transmission directions in each sub-band occur at different times, but simultaneous transmission can occur in different sub-bands in different transmission directions. The message is received entirely in one transmission direction before it needs to be responded to in another transmission direction in a particular sub-band. The frequency band is utilized effectively for communication because transmission can be performed simultaneously in different sub-bands in the reverse transmission directions.

摘要： The invention relates to a mechanism for providing location information regarding mobile terminals, especially regarding WLAN terminals. In order that the known mechanism for locating users of a mobile cellular network could be utilized for locating WLAN terminals, a location service request concerning a WLAN terminal is received and routed by the same network elements that receive and route location service requests concerning users of a mobile cellular network. However, in the case of a WLAN terminal the location service request is diverted to a predetermined network element, where the access point currently serving the WLAN terminal is identified. The location information corresponding to the said access point is then determined, and the location information is returned as the location of the terminal. The location of the serving WLAN access point thus represents the location of the WLAN terminal.

摘要： Systems and methodologies are described herein that facilitate efficient packet differentiation and forwarding in a wireless communication system. As described herein, identifiers or tags (e.g., corresponding to radio bearers, logical channels, Internet Protocol (IP) addresses, etc.) can be applied to respective packets based on their destinations as determined by traffic flow templates (TFTs) associated with the packets. Further, techniques are provided for establishing radio bearers, IP addresses, and/or other resources for transmission of packets associated with respective TFTs in a manner irrespective of associated quality of service (QoS) policies for the TFTs. Upon an establishment of resources, techniques are described herein for tagging packets with resources associated with TFTs corresponding to the packets to facilitate forwarding of respective packets to their intended destinations with lowered required processing cost. Additionally, techniques are described herein for offloading packet analysis and/or forwarding functionality from a terminal to a device tethered to the terminal.

摘要： Local breakout is provided by one or more nodes (e.g., a local access point and/or a local gateway) in a wireless network to facilitate access to one or more local services. In conjunction with local breakout, multiple IP points of presence relating to different levels of service may be provided for an access point. For example, one point of presence may relate to a local service while another point of presence may relate to a core network service. IP point of presence may be identified for an over-the-air packet to indicate a termination point for the packet. Also, different mobility management functionality may be provided at different nodes in a system whereby mobility management for a given node may be provided by a different node for different types of traffic. Thus, an access terminal may support multiple NAS instances. In addition, different types of paging may be provided for different types of traffic. Furthermore, messages associated with one protocol may be carried over another protocol to reduce complexity in the system.

摘要： The invention is directed to a method for controlling delays in a cellular telecommunications network. The delay control method according to the invention is based on a hierarchical structure of delay controlling entities, which preferably communicate only with entities directly above or below them in the hierarchy. In the downlink direction, an entity receiving data, such as a base station or a splitting unit, sends a timing report to the entity sending the data if the data is received too early or too late, whereafter the sending entity may adjust the sending time of data. The same reporting and adjusting process may be repeated through all levels of the control hierarchy, resulting in a collective control of delays from the top of the hierarchy, for example from a RNC, to the bottom, for example to a base station. In the uplink direction, a higher level entity receiving data from a lower level entity may command the lower level entity to adjust the sending time, if the data is received too early or too late. When the same action is repeated in all levels of the hierarchy, a collective control of delays is achieved for the link between the lowest level, e.g. the base station, and the highest level, e.g. a RNC.

摘要： In connection-oriented switching of packet data in known mobile communications systems, resources of the transmission path between the serving node (SGSN) and the radio network subsystem (RNS) and memory resources of the radio network subsystem are reserved unnecessarily due to the burst-like nature of packet data. Thus the transmission network's limited address space and the radio network subsystem's management resources are consumed. The invention concerns such connection management in a mobile communications system, which is suitable for packet-switched data transmission. The method according to the invention is characterized in that the logical connection between the serving node (SGSN) and the radio network subsystem (RNS) is released, so that the logical connection between the serving node (SGSN) and the mobile station (MS) remains, and the released logical connection is reconnected, when relaying of user data starts.

摘要： The present invention relates to a method and system for providing access from a first network (30) to a service of a second network, wherein an authentication signaling is used to transfer a service selection information to the second network (70). Based on the service selection information, a connection can be established to access the desired service. Thereby, cellular packet-switched services can be accessed over networks which do not provide a context activation procedure or corresponding control plane signaling function.
