Detailed Description

As MTC communication differs from existing mobile network communication: different market conditions, different data communication modes, lower cost and labor investment of MTC communication, a potentially large number of communication terminals in the MTC communication, and a large number of small data packets in the MTC communication. Based on the above characteristics of MTC communication, when a large number of MTC devices are deployed, if a core network directly controls each MTC device, a large number of signaling interactions may be generated, thereby occupying a large amount of wireless resources and core network resources, and seriously affecting the service quality of the network.

Based on the above problems, embodiments of the present invention provide a data transmission method and device, where a new network element MTCC (MTC Controller) is introduced between an MTC device and an E-UTRAN access network by optimizing an MTC communication architecture, and the MTC device is centrally managed through the MTCC, so that an amount of signaling interaction with a core network during MTC communication is reduced, a load of the core network is reduced, a service quality of the network is improved, and a resource utilization rate is improved.

The technical solutions in the present invention will be described clearly and completely with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

An application scenario of the method is shown in fig. 3, where a new network element MTC controller is introduced between an MTC device and an E-UTRAN access network, and the MTC device is configured with a policy through the MTC controller, so as to optimize a load of the network.

Specifically, the MTC controller is configured to centrally manage static MTC devices (such as a meter reader and a monitor) within a certain range, aggregate data of each MTC device, and send the aggregated data to the MTC server according to a relevant policy, thereby optimizing MTC communication.

In the embodiment of the present invention, the MTC controller may provide multiple air interfaces for the MTC devices to access, and the MTC devices in different systems may access the MTC controller through different air interfaces, where the air interfaces include but are not limited to: an E-UTRAN Wireless interface and a WLAN (Wireless Local Area network) Wireless interface provided by the MTC controller. Of course, the practical application is not limited to the E-UTRAN radio interface and the WLAN radio interface, and the types of interfaces that can access the MTC controller are within the scope of the embodiments of the present invention.

For example, the MTC controller can provide an E-UTRAN wireless interface, and MTC equipment supporting the E-UTRAN accesses the MTC controller through the E-UTRAN wireless interface; the MTC controller can provide a WLAN wireless interface, and the MTC equipment supporting the WLAN accesses the MTC controller through the WLAN wireless interface.

As shown in fig. 4, the method comprises the steps of:

in step 401, the MTC controller receives data from the MTC device.

In view of the characteristics of a potentially large number of communication terminals (i.e., MTC devices) and a large number of small data packets during MTC communication, the MTC controller may receive data from a plurality of MTC devices (i.e., small data packets containing only a small amount of data).

Step 402, the MTC controller obtains the traffic type of the data.

The service type of the data includes but is not limited to: VoIP service type, stream service type, alarm service type, download service type, Internet service type, etc.; the data can carry the identifier corresponding to the service type, and after the MTC controller learns the identifier carried in the data, the MTC controller can learn the service type of the data.

For example, when the learning identifier is 1, the service type of the data is a VoIP service type; and when the learning identifier is 5, the service type of the data is known to be an alarm service type.

And step 403, the MTC controller aggregates the data according to the service type of the data. The MTC controller is used for carrying out aggregation and integration on data of the same service type.

For example, for data from MTC device 1, MTC device 2, and MTC device 3 with the same service type, the MTC controller may aggregate the data of the three devices together, i.e. organize the data of the three devices into a new data packet.

For another example, for a WLAN MTC device and an LTE (Long Term Evolution) MTC device in a meter reading class, the MTC controller may aggregate data of MTC devices in two different systems (the data of the MTC devices in different systems in the meter reading class have the same service type).

Of course, the MTC controller may also aggregate data from different MTC devices in the same system, which is not described herein again.

And step 404, the MTC controller sends the aggregated data to the MTC server according to the service strategy corresponding to the service type. The MTC controller can set different service strategies aiming at different service types, and sends data of corresponding service types to the MTC server according to the service strategies.

When the aggregated data is sent to the MTC server, the MTC controller can send the data to the MTC server through the E-UTRAN wireless interface; data may also be sent to the MTC server over the WLAN wireless interface.

For example, for a meter reading type MTC device (a meter reading type WLAN MTC device or an LTE MTC device), when the MTC controller receives data of the MTC device, it can be known that the corresponding service policy does not need to send the data to the MTC server in time by acquiring the service type of the data, that is, the MTC controller does not need to forward the data to the MTC server in time; the MTC controller can gather and cache received data (data with meter reading service types), and select a time period with light network load to report the gathered data to the MTC server.

For another example, for monitoring an alarm service, the real-time requirement needs to be ensured, and after the MTC controller receives data sent by such devices, by obtaining the service type of the data, it can be known that the corresponding service policy is that the data needs to be sent to the MTC server for processing in time, that is, the MTC controller needs to forward the data to the MTC server in time; the MTC controller assembles the received data (the data with the monitoring alarm service type) and immediately reports the assembled data to the MTC server.

In summary, in the embodiments of the present invention, by aggregating data with the same service type and sending the aggregated data to the MTC server, the amount of interactive signaling between the MTC server and the core network during MTC communication can be greatly reduced, and the load of the core network is reduced. Furthermore, the MTC controller performs policy control on data sent by the MTC equipment according to the service type, so that the network can be further optimized.

It should be noted that, in the embodiment of the present invention, when the MTC controller sends the aggregated data to the MTC server according to the service policy corresponding to the service type, the MTC controller may define different priorities for the service types according to characteristics of each service type, then set different service policies for different service types according to the priorities, and control according to the service policies, that is, send the data of the corresponding service type to the MTC server according to the service policies.

For example, for monitoring an alarm service, a highest priority may be set, where the service type of the highest priority has a service policy for sending data in real time, that is, when control is performed according to the service policy, the data of the monitoring alarm service is sent to the MTC server in real time; for the internet service, a second level of priority may be set, where the service type of the second level of priority has a service policy of sending data every 30 minutes, that is, when control is performed according to the service policy, the data of the internet service is sent to the MTC server every 30 minutes.

In order to more clearly illustrate the technical solutions provided by the embodiments of the present invention, the following further description is provided in conjunction with specific application scenarios.

Taking the application scenario of MTC communication with MTC controller shown in fig. 5 as an example, in fig. 5, there are four MTC devices, where MTC device 1 and MTC device 2 belong to a meter reading service, and MTC device 3 and MTC device 4 belong to a monitoring alarm service; the MTC device 1 and the MTC device 3 are accessed to the MTC controller through an E-UTRAN air interface, and the MTC device 2 and the MTC device 4 are accessed to the MTC controller through a WLAN air interface.

For the data sent by the MTC device 1 and the MTC device 2, the MTC controller uniformly assembles and caches the data, and selects a time period with a lighter network load to send the assembled data to the MTC server. For the data sent by the MTC devices 3 and 4, the MTC controller immediately forwards the data to the MTC server to ensure real-time monitoring of the alarm-like traffic.

Example two

The second embodiment of the invention provides a data transmission method, wherein a new network element MTC controller is introduced between MTC equipment and an E-UTRAN access network, and strategy configuration is carried out on the MTC equipment through the MTC controller, so that the load of the network is optimized.

In the embodiment of the invention, in order to prevent impact on the MTC controller caused by the fact that a large number of MTC devices simultaneously send data to the MTC controller, a plurality of MTC controllers can be deployed for one region according to a region range so that the MTC devices can select the MTC controllers to access according to actual needs, and the plurality of MTC controllers share the pressure of the MTC service together.

As shown in fig. 6, the method comprises the steps of:

step 601, the MTC device records information of the MTC controller. After a plurality of MTC controllers are deployed, the MTC device may record information (such as addresses of the MTC controllers and identifiers of the MTC controllers) of the MTC controllers in a region range of the MTC device according to the region range of the MTC device.

In the embodiment of the invention, when the MTC equipment is initially configured, a unique MTC controller can be fixedly configured for the MTC equipment, and the MTC equipment records the information of the MTC controller; and when the MTC equipment is initially configured, configuring an MTC controller list for the MTC equipment, wherein the MTC controller list comprises a plurality of MTC controllers, and the MTC equipment records the information of the plurality of MTC controllers.

Step 602, when data needs to be sent to the MTC server, the MTC device selects an accessed target MTC controller.

When the MTC equipment is accessed, if only one MTC controller is configured for the MTC equipment, the MTC equipment directly selects the MTC controller as a target MTC controller; if an MTC device is configured with an MTC controller list (comprising a plurality of MTC controllers), the MTC device selects any MTC controller from the MTC controller list as a target MTC controller. It should be noted that when configuring one MTC controller list, if one MTC controller fails, the MTC device may select another MTC controller as the target MTC controller.

When any MTC controller is selected from the MTC controller list as a target MTC controller, the following method may be adopted:

(1) the polling method comprises the following steps: each MTC device sequentially selects MTC controllers in an initially configured MTC controller list as target MTC controllers; for example, the MTC device 1 selects the MTC controller 1 in the MTC controller list as a target MTC controller, and the MTC device 2 selects the MTC controller 2 in the MTC controller list as a target MTC controller.

(2) The random method comprises the following steps: the MTC equipment randomly selects one MTC controller from the MTC controller list as a target MTC controller through a random algorithm.

(3) Modulus method: the MTC device performs modulo operation on the device identification code of the MTC device by taking the number of items in the configured MTC controller list as a modulus, and selects a corresponding MTC controller in the MTC controller list as a target MTC controller according to the obtained number.

Step 603, the MTC device sends data to the target MTC controller. After the target MTC controller is selected, the MTC device may send data to the target MTC controller, that is, the MTC device may initiate an access procedure to the target MTC controller according to an address of the target MTC controller.

Specifically, the MTC equipment sends data to the target MTC controller through an E-UTRAN wireless interface, and the E-UTRAN wireless interface is used for supporting the MTC equipment of the E-UTRAN to access the MTC controller through the E-UTRAN wireless interface; or the MTC device WLAN wireless interface sends data to the target MTC controller, and the WLAN wireless interface is used for enabling the MTC device supporting the WLAN to access the MTC controller through the WLAN wireless interface.

In summary, in the embodiments of the present invention, the MTC devices select one target MTC controller from the MTC controller list to access, so that the number of the MTC devices accessed by each MTC controller is substantially balanced, and the possibility that a single MTC controller is impacted by a large amount of MTC signaling is reduced.

EXAMPLE III

Based on the first embodiment and the second embodiment, a third embodiment of the present invention provides a data transmission method, where a new network element MTC controller is introduced between an MTC device and an E-UTRAN access network, and the MTC device is configured with a policy through the MTC controller, so as to optimize the load of the network. As shown in fig. 7, the method comprises the steps of:

in step 701, the MTC device records information of the MTC controller.

Step 702, when data needs to be sent to the MTC server, the MTC device selects a target MTC controller to be accessed.

Step 703, the MTC device sends data to the target MTC controller.

The processing procedures of steps 701 to 703 are similar to the processing procedures of steps 601 to 603 in the second embodiment, and are not repeated here.

In step 704, the MTC controller (i.e. the target MTC controller to which the MTC device selects to access) receives data from the MTC device.

Step 705, the MTC controller obtains the service type of the data.

And step 706, the MTC controller aggregates the data according to the service type of the data.

And 707, the MTC controller sends the aggregated data to the MTC server according to the service policy corresponding to the service type.

The processing procedure of steps 704 to 704 is similar to the processing procedure of steps 401 to 404 in the first embodiment, and is not repeated here.

In addition, by aggregating data with the same service type and sending the aggregated data to the MTC server, the interactive signaling amount between the MTC server and the core network in the MTC communication process can be greatly reduced, and the load of the core network is reduced. Furthermore, the MTC controller performs policy control on data sent by the MTC equipment according to the service type, so that the network can be further optimized.
