Consequently, restricted radio resources can be efficiently used.

A method and an apparatus for data transmission in a mobile telecommunication system supporting an enhanced uplink service are provided.

Rate charging rules and principles concerning mobile calls in a cellular communication system can be improved by providing the mobile station with a locator object which, at certain intervals, determines the cell in which the mobile station is currently located. Stored in the mobile station is a list of cells or areas in which a special rate is to be applied in charging for calls originating from the mobile station. The locator object monitors calls made from the mobile station and, when it detects that a call is being made, it determines whether the mobile station was in a denoted special rate area at the time that its location was most recently determined. If so, then the object informs the network that the call is entitled to the special rate. Since the last location function was executed just before call setup commenced, a special rate call is possible even if the mobile station has thereafter moved some distance into a cell applying a normal rate. Disposed in a billing center is a billing object, to which the locator object sends data indicating whether the call was initiated from a cell or area in which a special rate is applicable, as well as data identifying the particular call. The second object receives the billing records generated by the mobile switching center, which also contain call identifying data, and compares the call-specific data in those records with the data sent by the first object. In this way, the second object can identify from the billing records those calls that are entitled to a special rate, regardless of whether the mobile station has moved during call setup from the original cell into a cell where another rate, e.g. a higher rate, is applicable.

In this manner, for user equipment, e.g., a Universal Mobile Telecommunications System mobile station, a decision algorithm in a Universal Mobile Telecommunications System Terrestrial Radio Access Network may direct at least a part of the traffic load on a shared channel from a source cell to a target cell by moving a cell border without affecting a traffic load on a dedicated channel.

An inter system handovers in a mobile telecommunication system is performed when a dual mode user equipment (UE) covered by both GSM/GPRS network and UMTS network connects a dedicated channel and sets up a call in a BSS region where the GSM/GPRS provides coverage, and then moves to a UTRAN (UMTS Terrestrial Radio Access Network) where the UMTS provides coverage, wherein the method includes the steps of: if the dual mode UE receives an inter system handover command, i.e. from the BSS to the UTRAN, requesting GSM/GPRS data link layer to suspend a GSM/GPRS data link by a sublayer RR of GSM/GPRS network layer in the UE, requesting a GSM/GPRS physical layer to release a physical channel of the GSM/GPRS, and sending the inter system handover command to the UTRAN for authorizing a sublayer RRC of UMTS network layer in the UE to continue a call; requesting, at the RRC in the UE, a UMTS physical channel to be configured as a UMTS physical channel, and monitoring if the UMTS physical layer succeeds to have the configuration of the UMTS physical channel as requested; if the UMTS physical layer succeeds to have the configuration of the UMTS physical channel, requesting, at the RRC in the UE, a UMTS data link layer to configure a UMTS data link, and conveying information to the UTRAN through a UMTS channel that the handover between systems from the BSS to the UTRAN has been successfully performed; and sending, at the RRC, a GSM/GPRS resource release message to RR/GRR, thereby resetting the GSM/GPRS physical layer and the GSM/GPRS data link layer.

The present invention relates to a method and system of transmissions and retransmissions of packet data in a communications system, where the communications system uses switched channels, switching between rates or channels of different characteristics, and connection control and management in such a system.

In a cellular mobile telecommunications system the position of a mobile station can be estimated in terms of its bearing and range from a cell site. A multi-element direction finding antenna at the cell site receives signals from the mobile station and a receiver circuit estimates the bearing using the relative phase of signals received at different antenna elements and estimates the range by measuring round trip delay of signals to and from the mobile station. Motion of the mobile station can introduce errors into the bearing estimate due to frequency offset and frequency spread when element sampling is non-simultaneous. Compensation for these errors is introduced by using signal samples successively received at the same antenna element to estimate Doppler frequency offset and spread. It is necessary to ensure accurate calibration of the direction finding antenna and the receiver circuit. This is done by injecting calibration signals into the circuit near the antenna or into the antenna itself from a near field probe. Other aspects of calibration, such as antenna position, are calibrated using a remote beacon. A beacon emulating a mobile station but at a fixed, known location, or a beacon at an adjacent cell site may be used.

The present invention relates to methods and devices that allow for efficient transportation of traffic in conjunction with a home base station (1). Traffic arriving in the home base station from a mobile terminal (2) connected to the home base station can be transported by means of local breakout transportation, which implies that the traffic is forwarded to a local node (4) over a local network (20) or to the Internet (21) without passing a core network (15) of a mobile telecommunications system. A local breakout bearer (22) is established, which is a radio bearer that extends between the mobile terminal and the home base station. The mobile terminal forwards uplink traffic that is to be subject to local breakout transportation to the home base station on the local breakout bearer. Thus it is not required for traffic that is destined for local nodes or the Internet to pass the core network, which allows for efficient traffic forwarding.

The present invention relates to a wireless communication system and a terminal providing a wireless communication service and to a method by which a base station and a terminal transmit and receive data in an evolved universal mobile telecommunications system (E-UMTS) evolved from universal mobile telecommunications system (UMTS) or a long term evolution (LTE) system, and more particularly, to a method whereby, in requesting allocation of radio resources by a user equipment (UE), which has been allocated continuous allocation radio resources, from a base station, the UE compares an allocation time point of continuous allocation radio resources and a start time point of a radio resource request procedure and effectively transmit a radio resource allocation request.

In a mobile telecommunication system the transmission quality is dependent on a wide range of radio conditions. A method for extracting a useful estimation of the radio environment of a mobile station in communication in order to predict how the radio conditions will change in the near future for a considered mobile station in the near future. A measurement report is sent from the mobile station to the base station. The quality measure in the measurement report is filtered over the area by a smoothing filter (220), and then processed through an updating filter (230) resulting in a time varying map (240). Several maps are classified (260). Classified data are grouped (270) resulting in the final map, which is stored in a database (280). The final map may be used to enhance the performance of radio network algorithms.

A system and method are provided for sharing rights-enabled user profiles among users in voice communication system, such as a mobile telecommunications system. In general, each user defines a user profile and associated access rights, where the user profile and access rights are stored by or accessible to a profile service. When a voice session, or call, is initiated between a first and second user, a device of the first user requests a profile of the second user from the profile service. In response, the profile service determines whether the first user has been granted access rights to the user profile of the second user. If so, the profile service provides the user profile of the second user, or a portion thereof, to the device of the first user according to the access rights of the first user, and the user profile is presented to the first user.
