摘要:
A method of transmitting from a first node to a second node, said method comprising the steps of transmitting in a first mode at least one data frame from said first node to said second node; and determining if there is no data to be transmitted and if there is no data to be transmitted transmitting at least one empty frame in the first mode; and switching to a second mode in which no transmission is made in the absence of data to be transmitted at least some of the time.

A method of transmitting in a second mode at least one data frame from a first node to a second node. Determining if there is data to be transmitted and if there is no data to be transmitted then transmitting from said first node to said second node no frame in the second mode. The first node receiving an indication that the first node should use a first mode and transmitting an acknowledgement in response to the indication. Switching from the second mode to the first mode and transmitting in the first mode at least one data frame from the first node to the second node. Then, further determining if there is data to be transmitted and if there is no data to be transmitted then transmitting from said first node to said second node at least one empty frame in the first mode.

A method of establishing a communication in a mobile communication system includes two steps. The mobile communication system includes a core network and at least one user equipment connected thereto via a radio access network. The method includes providing at least two types of domain for carrying a predetermined datastream for the communication in the core network. The method also includes providing one of the types of domain for carrying the predetermined datastream in the radio access network.

An automatic repeat request mechanism (such as Type II/III hybrid ARQ) which includes (soft or hard) combining of initially transmitted and retransmitted versions of a packet, is provided for retransmission of erroneous packets. According to the present invention, in association with each retransmission, there is outband signaling from a transmitter to a receiver that unambiguously indicates when, e.g. the exact time or physical location, the first transmission of the packet was carried out, so that it is possible to combine the retransmitted version with the previous version(s) of the packet. Soft combining requires that the initial packet and the retransmitted packet be identical. In an embodiment of the invention, in order to overcome this problem, the information that needs to be changed between the initial transmission and the retransmission(s) of a packet is sent outband with other outband signaling information. Thus, the retransmitted packet can be maintained unchanged and the requirement for identical packets in soft combining is met.

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.

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.

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.

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.
