Definitions

  • WLAN wireless local area networks
  • the second generation (2G) GSM access systems can be upgraded by enhanced general packet radio service (EGPRS) capability to better meet the requirements for data streaming and so-called conversational traffic classes that have even tighter delay requirements than streaming services.
  • GPRS general packet radio service
  • Another option for enhancing the 2G is the dual-transfer mode (DTM) which provides a parallel 2G circuit switched and packet switched (CS, PS) service.
  • DTM dual-transfer mode
  • CS, PS packet switched and packet switched
  • 3G systems are commonly provided from the outset with a bitrate capacity that enables data streaming.
  • Embodiments of the present invention aim to address one or several of the above problems.
  • a method for transferring user equipment from a current cell during an ongoing communication the current cell belonging to a first network.
  • capability information for at least one available cell of a second network is determined in a controller of the current cell, where after at least one cell of the second network is selected based on the capability information for preparation of transfer of the user equipment from the current cell.
  • Information regarding the selected at least one cell of the second network is then sent from the controller to the user equipment.
  • a communication system comprising a first network, a second network, and a controller for controlling user equipment in a cell of the first network during ongoing communication.
  • the controller is configured to determine capability information for at least one available cell of the second network based on system information and to select at least one cell of the second network based on the capability information for preparation of transfer of the user equipment from the cell of the first network.
  • the controller also informs the user equipment in the cell of the first network of the selected at least one cell of the second network.
  • the invention is not limited to environments such as cellular mobile or WLAN systems either. What is required is that system level information of a first type of network can be used by a controller of another type network for selection of an access entity of the first type of network, and that the controller is enabled to command user equipment to choose a selected access entity.
  • the term cell is understood to refer broadly to an access entity that is provided by a communications network.

Abstract

L'invention concerne un procédé permettant de transférer un équipement utilisateur (EU) d'une cellule courante à une autre cellule pendant qu'une communication est en cours. La cellule courante appartient à un premier réseau. Ce procédé consiste à déterminer une information de capacité pour au moins une cellule d'un second réseau auprès du contrôleur de la cellule courante, et à sélectionner au moins une cellule d'un second réseau en fonction de cette information de capacité, afin de préparer le transfert de l'équipement utilisateur depuis la cellule courante, puis à transmettre une information concernant la ou les cellules du second réseau sélectionnées à l'équipement utilisateur à partir du contrôleur.
