The invention concerns a method for scheduling of service data intended to be sent from a base station (BS) over radio interfaces to a user terminal (UE) by means of at least one control message sent from the base station (BS) to the user terminal (UE), whereby said at least one control message comprises or allows for a determination of at least one of the orders when the user terminal (UE) shall perform reception of downlink data and when and under which circumstances the user terminal (UE) shall send HARQ feedback information in upcoming transmission time intervals (TTI), a base station (BS), a user terminal (UE) and a communication network therefor.

Method for scheduling of service data in downlink, a base station, a user terminal and a communication network therefor

In a wireless network, for example, an LTE network, the context information relating to a mobile terminal UE is transmitted to a plurality of network nodes eNBandfrom a source network node, eNB. One of the eNBis a handover target node and also reserves resources for the UE in anticipation of receiving it after handover. The other eNBsanddo not reserve resources. In the event of radio link failure, the UE may attach to one of the designated eNBsandthat have not reserved resources, but that do recognize the UE because they have received its context. The method reduces the likelihood of the UE needing to go via the time consuming IDLE state while only reserving resources at a handover target eNB.

Method and apparatus for radio link failure recovery in a wireless communications network

The present invention relates to an interface unit comprising a first component for establishing a connection to a radio network controller of a radio network sub-system by means of a first communication protocol, a second component for establishing a connection to at least one access point of a wireless local area network by means of a second communication protocol, a third component for converting the second communication protocol to the first communication protocol and for converting the first communication protocol to the second communication protocol and a fourth component for providing data indicative of a load situation of at least one access point to the radio network controller.

Hybrid UMTS/WLAN telecommunication system

A method for assigning of channel capacity to communication links in a cellular communication system and to an access controller for controlling the access of contending terminals to channel capacity of a cellular communication system is provided. One or more traffic parameters is determined for each of the communication links, and a requirement for channel capacity for each of the communication links is predicted based on the one or more traffic parameter. A channel capacity is then assigned to the communication link based on the predicted requirement.

Method for assigning of channel capacity to communication links

The present invention relates to a telecommunication method in a wireless cellular telecommunication system having a radio network controller and a base station, where the method receives a number of orthogonal variable spreading factor codes from the radio network controller by the base station, evaluates a load situation by the base station, and in case the orthogonal variable spreading factor codes received from the radio network controller are insufficient for the load situation: requesting a change of the number of orthogonal variable spreading factor codes from the radio network controller by the base station.

Method of distributing data packets of system software where the receiving units acknowledge only proper reception

A service-on-demand system (SYS) includes a facility (EIN) which is designed to assign transmission channels to terminals (END , END ). To accomplish this, the facility (EIN) contains two interfaces (S , S ) for connecting it to two groups of terminals (END , END ), a memory (MEMO) which holds an assignment table containing entries on currently available and currently busy transmission channels for transmitting services requested from terminals (END , END ), with a variable assignment of transmission channels to terminals (END , END ) being possible regardless of which group the terminals (END , END ) belong to, and a control unit (CTRL) which coordinates the assignment. Only those transmission channels can be assigned which are considered currently available in the memory (MEMO). The transmission channels are not permanently assigned to groups but are largely freely available to all terminals (END , END ). For example, a minimum number of freely available transmission channels may be reserved for each group, and the remaining channels may be used both by terminals of group and by terminals of group , etc., depending on traffic volume and demand. This provides flexibility and adapts the assignment of transmission channels automatically to the traffic volume.
