first embodiment
[0035]Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. With reference to FIG. 1, a configuration example of a gateway device 10 according to a first embodiment will be described. The gateway device 10 may be a computer device that operates as a processor executes a program stored in a memory. The gateway device 10 may be an SGW or a Gateway General Packet Radio Service (GPRS) Support Node (GGSN) defined in 3GPP.
[0036]The gateway device 10 includes a storage unit 11 and a transceiver 12. The storage unit 11 and the transceiver 12 may be software or a module that is processed as a processor executes a program stored in a memory. Alternatively, the storage unit 11 and the transceiver 12 may be hardware, such as a circuit or a chip. The transceiver may be a transmitter and a receiver.
[0037]The storage unit 11 stores temporarily allocated identification information that is temporarily allocated to a communication terminal and an eDRX pa...
second embodiment
[0042]A configuration example of a communication system according to a second embodiment will now be described with reference to FIG. 2. A communication system illustrated in FIG. 2 supports Long Term Evolution (LTE) as a wireless communication scheme and includes a communication system defined as an Evolved Packet System (EPS) in 3GPP. FIG. 2 is based on a drawing in FIG. 4.2.1-1 of TS 23.401 V 13.8.0.
[0043]The communication system illustrated in FIG. 2 includes a UE 40, an Evolved-Universal Terrestrial Radio Access Network (E-UTRAN) 41, an MME 42, a Home Subscriber Server (HSS) 43, an SGSN 44, a Serving Gateway (SGW) 45, a Packet Data Network Gateway (PGW) 46, a Policy and Charging Rules Function (PCRF) entity 47 thereinafter, referred to as PCRF 47), a UTRAN 48, a Global System for Mobile communications (GSM) (registered trademark) Enhanced Data Rates for Global Evolution (EDGE) Radio Access Network (GERAN) 49, and Operator's IP Services 50.
[0044]The MME 42 corresponds to the mob...
third embodiment
[0081]A flow of a packet receiving procedure according to a third embodiment will now be described with reference to FIG. 9. The flow of the processes in steps S30 to S40 of FIG. 9 is similar to the flow of the processes in steps S30 to S40 of FIG. 8, and thus the same reference characters as those in FIG. 8 will be given for description.
[0082]A Paging procedure illustrated in FIG. 9 differs from the Paging procedure illustrated in FIG. 8 in terms of a parameter set in a message transmitted in step S39 and thereafter.
[0083]The Paging message transmitted in step S39 of FIG. 9 includes the IMSI for identifying the UE 40, in addition to the GUTI allocated to the UE 40 or the S-TMSI included in the GUTI and the eDRX parameter associated with the UE 40, which are included in the Paging message illustrated in FIG. 8.
[0084]Now, information elements set in the Paging message will be described with reference to FIG. 10. FIG. 10 shows that two UE paging identities—UE Paging Identity and UE Pa...
