Description
Technical Field
The present invention relates to the field of Machine Type Communication (MTC) systems, and in particular, to a method and a system for uploading machine service data of an MTC system.
Background
The information is collected, processed and uploaded through various sensing means, received and processed through a network, and each application system is integrated to provide better service for users; the technology from the aspects of information acquisition, information transmission and information processing is integrated in the technical level; the integration of telecommunication networks, enterprise networks, even internet services and various enterprise, industry and family applications at the service level and the rise to urban and social applications are the targets of the development of world information processing.
With the intelligent application and the wide application of wireless communication in various industries, information interaction between machines and networks is possible. A Machine Type Communication (MTC) system, which is a mode in which a Machine device for information collection communicates with a network, has the following characteristics:
the method comprises the following steps that firstly, a plurality of communication devices are provided, and generally, data acquisition is included in application of each service industry, so that the related machine devices aiming at data acquisition are very large, for example, the electricity meter data statistics of each household of each city in the whole province;
the data flow is small, the machine equipment usually acquires and transmits data only when information acquisition is needed, the data flow is small, and continuous transmission is not needed;
the real-time requirement is low, the real-time requirement of data acquisition is not high, and the data acquisition can be completed in a relatively long time period;
and the power consumption is low, the machine equipment is usually not maintained manually, the battery cannot be replaced frequently, and the power saving is the primary consideration.
Because the current wireless communication system is mature, the scheme of realizing information acquisition of various industries based on the existing communication network is the scheme with the lowest cost and the easiest realization. However, based on the above four features, the existing wireless communication system needs to be improved to be suitable for the MTC system.
For example, for a UMTS wireless communication system, if a ue needs to transmit uplink data, no matter how small the traffic is, the ue must establish a Radio Resource Control (RRC) connection with the network side, establish and maintain the interaction of signaling data between the ue and the network side through the RRC connection, and then transmit machine service data. However, this way of transmitting machine service data may have the following problems for the MTC system: in the MTC system, there are many ues, each ue needs to establish RRC connection each time it sends data, but the actually transmitted data amount is very small, that is, the resource consumption caused by the transmission of signaling messages for transmitting small data traffic is far greater than the resource consumption of the transmitted data amount itself, so this resource waste needs to be avoided by using a better method.
If the resource consumption is reduced by only reducing the signaling data caused by RRC connection establishment, the solution can be achieved by always-on user equipment without changing the prior art, but the always-on mode inevitably causes power consumption increase compared with the idle mode, and is contrary to the low power consumption feature of the machine terminal.
Disclosure of Invention
In view of the above, the main objective of the present invention is to provide a method and a system for uploading machine service data in an MTC system, so that a machine terminal performs interaction of signaling information as little as possible when uploading the machine service data, so that the utilization rate of wireless resources can be maximized, and the power saving requirement of the machine terminal can be ensured.

and the machine terminal compares the identifier of the machine terminal group to which the machine terminal belongs with the identifier of the machine terminal group carried by the unidirectional non-response signaling, and when the identifiers are consistent, the machine terminal uploads machine service data to network side equipment through public radio bearer resources.
The method further comprises the following steps: the network side equipment and the machine terminal reserve the public radio bearer resource in advance;
the common radio bearer resource comprises: an enhanced dedicated physical data channel, an enhanced dedicated channel, a common control channel, and a mapping relationship between the three.
Before the machine terminal uploads the machine service data, the method further comprises the following steps: and the machine terminal acquires the public wireless bearing resource in a competition mode and uploads machine service data to network side equipment through the public wireless bearing resource.
The machine terminal obtains the public radio bearer resource in a competitive manner, specifically:

Detailed Description
The technical solution of the present invention is further elaborated below with reference to the drawings and the specific embodiments.
The main idea of the machine service data uploading scheme of the MTC system is as follows: the network side equipment sends a one-way no-response signaling to the machine terminal, and the machine terminal directly uploads machine service data to the network side equipment without returning an uplink response aiming at the signaling to the network side equipment or establishing RRC connection after receiving the one-way no-response signaling.
As shown in fig. 1, the flow of the machine service data uploading method of the MTC system of the present invention includes the following steps:
step 101, a network side device sends a one-way no-response signaling to a specific machine terminal.
The machine terminal refers to a device type for performing machine type communication, such as a code table, a sensor, a digital camera, medical electronic equipment, and the like.
The specific machine terminal can be one, a plurality of, a group and/or a plurality of groups of machine terminals, and the network side equipment sends the one-way no-response signaling to the specific machine terminal according to the requirement.
The one-way no-response signaling may preferably adopt paging type one signaling or paging type two signaling in 3GPP 25.331 protocol, or may be other notification signaling for notifying the machine terminal to upload the machine service data, and the network side device may send the one-way no-response signaling to the specific machine terminal through a paging channel.
Preferably, the network side device sets an indication field (the value of the field can be set at will) in the one-way no-reply signaling to indicate that the machine terminal does not perform uplink reply to the one-way no-reply signaling, i.e., does not reply to the network side device; in addition, the specific device, i.e., the device terminal, and the specific service type, i.e., the device service, determine that the device terminal does not initiate an RRC connection request, i.e., does not establish an RRC connection, when receiving the one-way no-reply signaling.
Step 102, the machine terminal receiving the one-way no-response signaling directly uploads machine service data to the network side device through the public radio bearer resource without performing uplink response to the one-way no-response signaling and without establishing RRC connection.
It should be noted that, when one unidirectional non-reply signaling carries one or more machine terminal identifiers and/or one or more machine terminal group identifiers, the network side device sends the one or more machine terminal identifiers to the corresponding one or more machine terminals and/or all machine terminals in the one or more machine terminal groups, and a specific implementation will be described with reference to the following embodiments.
The machine terminal receiving the one-way no-response signaling compares the machine terminal identifier carried therein, or the machine terminal group identifier with its own identifier (i.e., machine terminal identifier), or with the identifier of the machine terminal group to which the machine terminal belongs (i.e., machine terminal group identifier), and when the two are consistent, the machine terminal uploads its machine service data to the network side device, which will be described in the following embodiments.
In addition, the common radio bearer resource is pre-agreed by the network side device and the machine terminal, for example, the machine terminal stores the available common radio bearer resource information in advance, or the network side device notifies the machine terminal of the available common radio bearer resource information in advance. The common radio bearer resource includes: physical channel resources: enhanced dedicated physical data channel, transport channel resources: enhanced dedicated channel, logical channel resources: common control channel, and mapping relationship between the three: the common control channel is mapped to an enhanced dedicated channel, which is mapped to an enhanced dedicated physical data channel. The machine terminal can upload the machine service data of the machine terminal to the network side equipment through the public radio bearer resource. Specifically, the transmission of machine service data on the common radio bearer resource is the prior art, and is not described herein again.
When uploading machine service data, a machine terminal receiving a one-way no-response signaling first acquires a public radio bearer resource in a competitive manner, specifically: a machine terminal randomly selects an available access sub-channel provided by network side equipment and a characteristic symbol corresponding to the access sub-channel; the machine terminal sends the characteristic symbol to the network side equipment through the access subchannel; when the machine terminal detects the access permission indication from the network side equipment, the machine terminal successfully competes to obtain the public radio bearer resource for uploading the machine service data.
After the network side device receives the characteristic symbol sent by the machine terminal, when the machine terminal is allowed to upload machine service data as required, the access permission indication is sent to the machine terminal through the capture indication channel, so that the machine terminal successfully competes, and meanwhile, a public wireless bearing resource for uploading the machine service data is obtained, and the machine service data of the machine terminal is uploaded by using the public wireless bearing resource.

In this embodiment, the paging type one signaling carries a machine terminal identifier, for example, 11, and the network side device sends the paging type one signaling to the machine terminal identified as 11.
Step 230: the machine terminal with the identifier 11 which receives the paging type one signaling does not establish the RRC connection and does not perform uplink response to the signaling according to the indication field in the paging type one signaling, but directly uses the common radio bearer resource to upload the machine service data:
