Uplink data processing method and equipment for machine type communication equipment
What is Al technical title?
Al technical title is built by PatSnap Al team. It summarizes the technical point description of the patent document.
A machine-type communication and line data technology, applied in network data management, wireless communication, data exchange network and other directions, can solve the problem that the destination IP address of the UE application layer cannot be modified, the destination IP address of the application layer cannot be recorded, and the MTC new model cannot be realized. features, etc.

This helps you quickly interpret patents by identifying the three key elements:
At the same time, there is no place in the network to save the destination IP address of the uplink data of the application layer
[0005] Therefore, the deficiency of the prior art is that: for the MTC application that all user data are required to be sent to the same destination IP address, in fact the existing network does not record the application layer destination IP address, so it cannot be obtained from the existing Even if the destination IP address is obtained from the network, it is actually impossible to use the destination IP address provided by the network to replace the original IP address specified by the application layer in the packet.
That is to say, there is currently no technical solution capable of realizing the new features of MTC proposed in TS22.368v2.0.0

Embodiment 1
[0057] figure 2 It is a schematic diagram of the implementation flow of the uplink data processing method of the MD in Embodiment 1, as shown in the figure, may include the following steps:
[0058] In step 201, the MD initiates an Attach Request (attach request) or a PDN Connectivity Request (PDN connection request).
[0059] In step 202, the MME / SGSN obtains the subscription data of the MD and learns that the MD has the property that the destination IP of the uplink data needs to be modified, and the MME / SGSN obtains a special APN indicating such property.
[0060] Step 203: If MME / SGSN is used to obtain the destination IP of uplink data, then MME / SGSN uses a special APN to obtain the PGW address supporting this feature and the destination IP address of MD uplink data through DNS query or static configuration, otherwise MME / SGSN only obtains PGW addresses that support this feature.
[0061] Step 204, if the MME / SGSN is used to obtain the destination IP of the uplink data,...
Embodiment 2
[0067] image 3 It is a schematic diagram of the implementation flow of the uplink data processing method of the MD in Embodiment 2, as shown in the figure, which may include the following steps:
[0068] Step 301, HLR / HSS carries the subscription information of MD in the Update Location Ack (location update confirmation) message, which includes the destination IP address of the uplink data;
[0069] Step 302, carrying OptionalIE: network provided destination IP address (the destination IP address provided by the network) in the Create Session Request message, and sending it to the PGW;
[0070] Step 303: After receiving the Create Session Request message with this OptionalIE, the PGW considers that the destination IP address of the uplink data packet transmitted over the PDN connection needs to be replaced, so it records the destination IP address of the uplink data indicated by the IE in the PDN Connection Context address.
[0071] Step 304: After receiving the uplink data...

Abstract
The invention discloses an uplink data processing method and uplink data processing equipment for machine type communication equipment. The method comprises that: in the attach request and / or packet data network connection request process of the machine type communication equipment, a packet data network gateway acquires a destination Internet protocol (IP) address of uplink data of the machine type communication equipment; the packet data network gateway records the destination IP address of the uplink data of the machine type communication equipment; and after receiving the uplink data on packet data network connection, the packet data network gateway replaces a destination address of an uplink data packet on the packet data network connection by the recorded destination IP address of the uplink data. By the method and the equipment, the characteristic of directing all the uplink data of the machine type communication equipment to the same destination address provided by a network is realized.
Description
technical field [0001] The invention relates to inter-machine communication, in particular to a method and device for processing uplink data of a machine-type communication device. Background technique [0002] M2M (Machine-to-Machine, machine-to-machine) communication refers to the general term of a series of technologies and technology combinations that apply wireless mobile communication technology to realize data communication and interaction between machines and machines, and between machines and people. In the SA1 working group report TS22.368v2.0.0 of the first phase of 3GPP, an MTC (Machine Type Communications) feature of "Network Provided Destination for Uplink Data (Network Provided Destination for Uplink Data)" is defined. The requirement is: for those MDs (MTC Devices, MTC devices) that are not convenient to pre-configure destination IP (Internet Protocol, Internet Protocol) addresses during production, but require all user data to be sent to the same destination...
