Embodiment Construction

[0036] Embodiments of the present invention provide a data transmission method and device for realizing uplink small data transmission by SGSN / MME through an MTC-IWF entity.

[0037] Considering that in the MT communication scenario, when the MTC-IWF entity queries the Home Subscriber Server (HSS) for the internal ID of the UE, such as the International Mobile Subscriber Identifier (International Mobile Subscriber Identifier, IMSI), the HSS can record The address of the MTC-IWF entity, therefore, the SGSN / MME can query the HSS through the S6a / d interface for the MTC-IWF entity that has previously served the UE; in the MO communication scenario, if an MTC-IWF entity has served a certain UE, then The HSS can also record the MTC-IWF entity, so that the SGSN / MME can directly select the MTC-IWF entity according to the record in the HSS.

[0038] see Figure 4 , a method for determining an MTC-IWF entity provided by an embodiment of the present invention includes steps:

Abstract

Disclosed are a data transmitting method and apparatus, so that an SGSN / MME can transmit uplink small data through an MTC-IWF entity. The data transmitting method provided by the present invention comprises: receiving an uplink small data; determining an MTC-IWF entity; and transmitting the uplink small data through the MTC-IWF entity. In the present invention, the SGSN / MME can transmit uplink small data through the MTC-IWF entity, which shortens a path for small data transmission and reduces consumption of network signaling resources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and device. Background technique [0002] Currently stipulated in the protocol 3GPP TS 23.888, a machine-type communication (Machine-Type Communication, MTC) architecture is introduced into the 3GPP network architecture, in which a new node is added between the MTC server (server) and the 3GPP core network -- the machine-type A Machine-Type Communication Interworking Function (MTC-IWF) entity, the main function of the MTC-IWF entity is to shield the topology of the 3GPP network from the MTC server and provide an interface with the 3GPP network. At present, the 3GPP protocol has discussed how the MTC server finds the MTC-IWF entity. However, how to find the MTC-IWF entity for the Serving GPRS Support Node (Serving GSN, SGSN) / Mobility Management Entity (MME) has not yet been discussed. [0003] MTC system architecture is divided into roami...
