SERVICE-AWARE QUALITY MONITORING AND CONTROL IN A RADIO ACCESS NETWORK

摘要

A system and method for monitoring performance of an identified end-user service in a radio access network, RAN, (12) in which multiple services utilize the same bearer service. A core network node such as an SGSN (42) includes an operator-configurable mapping table (45) for mapping end-user services to Service Identifiers (46). The SGSN sends a Service Identifier to the RAN, preferably at bearer establishment or modification. Service event counters in the RAN (12) are configured to measure performance parameters for the identified end-user service. The Service Identifier (46) may be sent as a tag in a radio bearer request or modify message (31). and the RAN may be configured to apply different parameter settings for network counters depending on the service identifier tag received in the radio bearer request message.
