摘要
FIELD: radio engineering, communication.;SUBSTANCE: in the method and system for correcting the access point name (APN) in the GPRS data roaming scenario, when using the sponsor network, and in the method and system for sending GTP messages to the proper destination network entity after activation of the APN correction, if required, the GTP filter checks the IMSI and APN data at the GTP level and, depending on the IMSI and APN data, performs the APN correction and manipulates the GTP parameters to ensure that the PDP context is correctly established between the SGSN and the GGSN, and additional control messages or the GTP data bypasses the GTP filter application.;EFFECT: proper message routing, in particular for the message coming into and out of the smartphone.;16 cl, 4 dwg, 2 tbl
