METHOD AND SYSTEM FOR PROVIDING RADIO ACCESS BEARER CHANGE SERVICE FOR MOBILE COMMUNICATION TERMINAL BY USING LOCATION INFORMATION ON WCDMA NETWORK

摘要

The present invention relates to a system and method for providing a radio access bearer change service to a mobile communication terminal using location information.;The present invention provides a method for providing a radio access bearer (RAB) change service to a mobile communication terminal using location information in a wideband CDMA (WCDMA) network, comprising: (a) SGSN ( Receiving a packet data protocol context activation request (Activate_Packet_Data_Protocol_Context_Request) message from a mobile communication terminal by a Serving GPRS Support Node (hereinafter referred to as 'SGSN'); (b) obtaining information about a radio control station (RNC: Radio Network Controller (RNC)) used by the mobile communication terminal from the location information of the mobile communication terminal; (c) checking whether the RNC used by the mobile communication terminal supports the RAB change function; (d) if it is determined in step (c) that the RNC used by the mobile terminal does not support the RAB change function, obtaining the maximum bandwidth information allowed for the mobile communication terminal from the location information; (e) Sending a packet data protocol context creation request (Create_Packet_Data_Protocol_Context_Request) message to a general GPRS support node (GGSN) to allocate the maximum bandwidth allowed to a mobile communication terminal, and receiving a packet data protocol context creation response (Create_Packet_Data_Protocol_Context_Response) message from the GGSN. Making; And (f) transmitting a RAB assignment request (RAB_Assignment_Request) message to the RNC and receiving a RAB assignment response (RAB_Assignment_Response) message from the RNC that has completed RAB assignment to the mobile communication terminal. It provides a method for providing a radio access bearer change service to a mobile communication terminal.;According to the present invention, after a mobile communication terminal accesses a wideband code division multiple access (WCDMA) network and performs location registration, the mobile communication terminal sends a packet data protocol context activation request (Activate_Packet_Data_Protocol_Context_Request) message to a Serving GPRS Support Node (SGSN). When transmitting, SGSN is a Radio Network Controller (RNC) based on the location information of the mobile communication terminal Radio Access Bearer (RAB) (hereinafter referred to as "RAB") Quality of Service (QoS) change function The RNC that supports the RAB change function and the RNC that does not support the RAB change function to the mobile terminal or WCDMA by changing to the maximum QoS allowed for the mobile terminal if the RAB change function is not supported. Stable service between mobile communication terminal and WCDMA system by providing certain quality of service (QoS) required by the system It has the effect of supporting the switch.;Location information, WCDMA, RNC, QoS, RAB, radio access bearer
