摘要:
Techniques for congestion management in a communication network are contemplated. For example, a wireless transmit receive unit (WTRU) may include a Radio Resource Control (RRC) layer and a Non-Access Stratum (NAS) layer. The RRC layer may receive an indication for a service, for example from the NAS. The indication may be interpreted as a request for the particular service indicated. For example, the indicated service may correspond to at least one of: a mobile originated (MO) voice communication, a circuit switched fallback (CSFB) supplementary service (SS), or a MO short message service (SMS). The RRC layer may receive a signal from a network indicating that one or more services provided by the network are allowed. The RRC layer may send a connection request to the network for the service sought by the NAS if that service is one of the one or more services allowed.
