Abstract

In an evolved UMTS terrestrial radio access network (E-UTRAN), paging may be performed using an international mobile subscriber identity (IMSI) or S-temporary mobile subscriber identity (S-TMSI). With the paging, a wireless transmit/receive unit (WTRU) may send an extended service request message to the E-UTRAN and perform circuit switched (CS) fallback.
