[0036] Embodiments of the present invention are described below with reference to the accompanying drawings. refer to figure 1 A structural example of a communication system according to the first embodiment of the present invention is described. figure 1 The communication system in includes a SCEF (Service Capability Exposure Function) entity (hereinafter referred to as SCEF) 10 , a control device 20 , a server device 30 and a communication terminal 40 . The SCEF 10, the control device 20, the server device 30, and the communication terminal 40 can be realized by a computer device that realizes operations by running a program stored in a memory on a processor.

[0037] The communication terminal 40 may be a mobile phone terminal, a smart phone terminal, a tablet terminal, or the like. Alternatively, the communication terminal 40 may be an M2M (Machine to Machine) terminal, an MTC (Machine Type Communication) terminal, an IoT (Internet of Things) terminal, or the like. The ...

[0048] Refer below figure 2 A structural example of a communication system according to a second embodiment of the present invention is described. figure 2 The communication system in includes SCEF 10 , MME 22 , SGSN 24 , RAN (Radio Access Network) 26 , AS 32 , SCS 34 and UE 42 .

[0049] MME 22 and SGSN 24 correspond to figure 1 The control device 20 in. AS 32 and SCS 34 correspond to figure 2 The server device 30 in. UE 42 corresponds to figure 1 The communication terminal 40 in. UE 42 is used as a general term for communication terminals in 3GPP.

[0050] The RAN 26 may be, for example, an eNB (Evolved Node B) supporting LTE (Long Term Evolution) communication, and it may be a NodeB supporting radio communication specified as so-called 3G communication in 3GPP and an RNC (Radio Network Controller) controlling the NodeB. ).

[0051] MME 22 and SGSN 24 may be referred to as CPF (C-Plane Function) entities (hereinafter referred to as CPF). The MME 22 and the SGSN 2...

no. 3 example

[0082] Refer below Figure 5 The flow of processing for SCEF 10 to receive information on allowed quotas and rates according to the third embodiment of the present invention will be described. In a second embodiment, SCEF 10 applies quota and rate control so as not to exceed the allowed quota and rate of non-IP data allowed by SCS 34 / AS 32 . On the other hand, in the third embodiment, quota and rate control is applied so as not to exceed the allowed quota and rate of non-IP data allowed by the UE 42 or the SCEF EPS bearer of the UE 42 . The SCEF EPS bearer of UE 42 is a bearer set between SCEF 10 and MME 22 for sending non-IP data between UE 42 and SCS 34 / AS 32 .

[0083] First, the SCS 34 / AS 32 sends a NIDD configuration request message to the SCEF 10 (S31). The NIDD Configuration Request message contains an External Identifier or MSISDN. The external identifier or MSISDN is information that identifies the UE 42 . The NIDD Configuration Request message also contains the ...

Abstract

An object of the present invention is to provide an SCEF entity capable of suppressing an increase in processing load related to communication between SCEF and MME in non-IP data communication. The SCEF entity (10) includes: a storage unit (11), which buffers the first non-IP data not transmitted to the communication terminal (40); When the second non-IP data of the terminal (40) is buffered with the first non-IP data, the transmission of the second non-IP data to the control device (20) in the mobile network is suppressed, and the second non-IP data is buffered to storage unit (11).

Description

technical field [0001] The present invention relates to a SCEF (Service Capability Exposure Function) entity, a communication terminal, a data processing method, a data receiving method and a program, and for example, to an SCEF entity, a communication terminal, a data processing method, a data receiving method for processing non-IP data methods and procedures. Background technique [0002] Nowadays, mobile communication technologies related to IoT (Internet of Things) are constantly being developed, and these technologies enable various devices (items) to have mobile communication functions, realize connection with the Internet or communicate with another device. One of the problems that needs to be solved when enabling devices with mobile communication functions is the reduction of power consumption. It is expected that sensor equipment or similar equipment will operate without maintenance for a long period of time, such as several years. Therefore, it is desired to redu...
