AI Technical Summary

Benefits of technology

This technology allows an access device (such as mobile phone) connected via wireless networks to automatically send out location updates without requiring any manual input like polling). It also helps reduce resource usage compared with traditional methods where users manually update their devices' locations on paper maps.

Problems solved by technology

This technical problem addressed in this patents relates to finding out what type of service called Unmann Group Services (UMGC)-based services are available over LTE networks without having any knowledge about their physical location when connecting them to certain domains like Home Location Registering System (HLR)).

Embodiment 1

[0068] The method for determining the MTC-IWF entity provided by the embodiment of the present invention includes:

[0069] If the MTC Server wants to trigger the UE to establish a connection, it first selects the MTC-IWF entity, and then sends the MTC Device Trigger (MTC Device Trigger) through the MTC-IWF entity;

[0070] After the selected MTC-IWF entity receives the MTC Device Trigger, it will use the UE's external ID to initiate an internal ID query to the HSS;

[0071] After receiving the internal ID query request, the HSS records the address of the MTC-IWF entity;

[0072] After the MTC Device Trigger is delivered to the UE, the UE needs to return the MTCDevice Trigger Report to the SGSN / MME;

[0073] When the SGSN / MME receives the Trigger Report, if there is no association with the MTC-IWF entity for this UE, for example, the previous MTC-IWF entity is overloaded and part of the association is released, or the MTC-IWF entity is restarting, etc., the SGSN / M...

Embodiment 2

[0077] The method for determining the MTC-IWF entity provided by the embodiment of the present invention includes:

[0078] A UE capable of transmitting small data needs to initiate small uplink data transmission, and the UE uses messages such as NAS Uplink Transport to carry small uplink data;

[0079] After the SGSN / MME receives the uplink small data, it judges that the uplink small data is sent in the IWF mode, then the SGSN / MME sends a request to the HSS to obtain the MTC-IWF entity address;

[0080] If the HSS has saved or statically configured the MTC-IWF entity address for this UE before, it will return the MTC-IWF entity address, such as Figure 4 As shown in steps A and C in ; otherwise, use the external ID of the UE or the FQDN of the configured MTC-IWF entity to initiate a DNS query, such as Figure 4 as shown in step B in;

[0081] HSS saves and returns MTC-IWF entity address to SGSN / MME;

[0082] The SGSN / MME determines the MTC-IWF entity through ...

Abstract

The invention discloses a method and an apparatus for determining a machine-type communication interworking function (MTC-IWF) entity. And the method and the apparatus are used for determining an MTC-IWF entity that is used for uplink data transmission, so that a serving GSN (SGSN)/MME can carry out uplink data transmission by the MTC-IWF entity. The method comprises the following steps that: a home subscriber server (HSS) determines an MTC-IWF entity according to an MTC-IWF entity address in subscription information of user equipment (UE), wherein the MTC-IWF entity address is configured in advance; or, when the HSS receives a message that is sent by an MTC-IWF entity and is used for request an internal identifier of the UE, an MTC-IWF entity address is recorded and the MTC-IWF entity is determined according to the recorded MTC-IWF entity address; or the HSS utilizes an UE external identifier in subscription information of the UE or an FQDN to search an MTC-IWF entity address from a domain name server (DNS), thereby determining an MTC-IWF entity.
