Definitions

  • the invention relates to a method for controlling a handover in radio communication systems.
  • radio communication systems signals are exchanged between radio terminals and base stations via a so called radio interface or air interface.
  • radio terminals are for example mobile or stationary user equipments (UE) .
  • base stations (NB - Node B) are access stations associ- ated with a land based communication network.
  • Examples of known radio communication systems are second generation digital mobile radio communication systems like GSM (Global System for Mobile Communication) based on TDMA (Time Division Multiple Access) and providing data rates up to 100 kbit/s, or third generation digital mobile radio communication systems like UMTS (Universal Mobile Telecommunication System) based on CDMA (Code Division Multiple Access) with data rates up to 2 Mbit/s.
  • GSM Global System for Mobile Communication
  • TDMA Time Division Multiple Access
  • CDMA Code Division Multiple Access
  • a context transfer or relocation between a source node and a target node should be employed. This relocation is inter alia mentioned in "Optimisation of SRNS relo- cation for real-time services" TSG-RAN WG #21, R2-011180, Bu- san, Korea, 21 st to 25 th May 2001, Agenda Item 9.2.3, Source Nokia.
  • Inter-RAT Radio Access Technologie
  • CS circuit switched domain services
  • Inter-RAT handover for PS (packet switched) domain services create additional problems for the transfer of an applied ROHC context in that the SGSN (Serving GPRS Support Node) and RNC (Radio Network Controller) do not possess a common protocol.
  • the SGSN Server GPRS Support Node
  • RNC Radio Network Controller
  • the hea- der compression is performed in the SNDCP in the SGSN
  • the header compression is performed in the PDCP (Packet Data Convergence Protocol) in the RNC.
  • PDCP Packet Data Convergence Protocol
  • An object of the invention is to provide a method for trans- ferring a protocol context during a handover procedure.
  • a first component transmits a handover request message to a second component.
  • the second component then transmits a message back to the first component, wherein the message contains information about a protocol context.
  • the first component transmits the handover request message inclu- ding the protocol context to the second component.
  • the inventive method makes an efficient use of existing message flows, thereby avoiding major changes to the systems ⁇ core network and RAN functionalities.
  • the invention is in ge- neral based on packet switched handover methods and message flows described in "Issues relating to PS Handover on an enhanced Gb", 3GPP GERAN Adhoc on A/Gb Evolution, Tdoc AHAGB- 006, Sweden, ll th -13 th June 2002, Source: Siemens.
  • the flow chart in the figure shows an example of a possible message exchange between various components of the radio com- munication system for a handover of a packet switched service.
  • the handover could for example be performed as a so called intrasyste handover within a GERAN based radio communication system, or as a so called intersystem handover from a GERAN based radio communication system to an UTRAN based radio communication system.
  • a similar flow chart could be defined for corresponding cell change procedures.
  • the SBSC Source Base Station Controller
  • MS Mobile Station
  • a message exchange procedure to handover the connection to respectively a TBSC (Target BSC) of the GERAN system or a RNC (Radio Network Controller) of an UTRAN system, in each case connected to a t-SGSN (Target-SGSN) .
  • the SBSC transmits a handover required message HO required to the s-SGSN (Source-SGSN) to which it is affiliated.
  • the s-SGSN replies to the received message by transmitting a HO reject message together with information related to the required ROHC context ROHC info.
  • This information is analysed in the SBSC and used to retransmit, in a third step (3) , the handover required message HO required to the s-SGSN, this time including the ROHC context ROHC info.
  • the s-SGSN subsequently forwards the handover request message HO required to the t-SGSN (tar- get-SGSN) of the target system, and the t-SGSN forwards it respectively to a TBSC (Target BSC) or to a RNC.
  • the TBSC or RNC then creates a new PDCP (Packet Data Convergence Protocol) for the handover, including the received new ROHC context ROHC info.
  • PDCP Packet Data Convergence Protocol
  • the described message flow is one in a variety of examples for an implementation of the method according to the invention, which, depending on the exact message flows to be deployed during a cell change or handover, could be modified accordingly.

Abstract

L'invention a pour objet un procédé permettant de commander un transfert intercellulaire. Selon ledit procédé, un premier élément (SBSC) transmet un message de demande de transfert à un second élément (S-SGSN). Le second élément transmet ensuite un message (rejet transfert) au premier élément, ledit message contenant des informations relatives à un contexte de protocole (info ROHC). Enfin, le premier élément retransmet au second élément le message de demande de transfert contenant les informations relatives au contexte de protocole.
