Description
Technical Field
The invention relates to a Machine-to-Machine (M2M) internet of things technology, in particular to a Machine-Type communication (MTC) service processing method and device.
Background
The appearance and the development of communication network technology bring great changes to social life, people can communicate with each other more quickly, and information exchange is smoother. However, currently only computers and other Internet Technology (IT) devices have such communication and networking capabilities, and a large number of common machine devices have little networking and communication capabilities, and these common machine devices without networking and communication capabilities include: home appliances, vehicles, vending machines, plant equipment, and the like.
As a key technology of a Machine-to-Machine (M2M) internet of things system, Machine-Type communication (MTC) has become an important research topic at present. M2M mainly refers to transmitting information to a background information system through a wireless network to realize real-time data exchange from machine to machine, i.e., machine interconnection and intercommunication. M2M is a generic term for all technologies that enhance machine device communication and network capabilities, and the goal of M2M technology is to enable all machine devices with networking and communication capabilities.
The M2M technology enables machines, devices, application processes to share information with background information systems and to share information with operators. M2M technology provides a means for devices to establish wireless connections between systems, remote devices, or with individuals in real time, thereby providing a means to transfer data. The M2M technology integrates data acquisition, Global Positioning System (GPS), remote monitoring, telecommunication, information technology, etc., is an ecosystem of computers, networks, devices, sensors, humans, etc., can automate business processes, integrate real-time states of corporate IT systems and non-IT devices, and create value-added services. The platform can be operated in the environments of safety monitoring, automatic meter reading, mechanical service and maintenance business, automatic vending machines, public transport systems, fleet management, industrial process automation, electric machinery, city informatization and the like, and provides wide application and solutions.
The M2M system mainly comprises a wireless terminal, a transmission channel and an industry application center, wherein the wireless terminal comprises various types of industry application terminals besides a common mobile phone and a notebook computer; the transmission channel is a data transmission channel from the wireless terminal to an industry application center; the industry application center is a convergence point of data uploaded by the wireless terminal and monitors the scattered wireless terminals.
The M2M technology has very important significance, has wide market and application, and promotes a new revolution of social production and life style, and the third Generation Partnership Project (3GPP, 3rd Generation Partnership Project) is working on establishing a unified M2M communication interface and standardized transmission content.

The number of connections for the M2M device is very large. In future wireless communication systems, 3G networks will also exist for a long time. In order to support MTC application, a Network side needs to allocate a UTRAN radio Network temporary Identity (U-RNTI) to UE in a connected state, and the U-RNTI totally 32 bits consists of two parts: a radio network controller identity (SRNC identity) and a radio network controller temporary identity (S-RNTI, SRNC RNTI). Wherein, SRNC identity represents service RNC identification, meaning is the same as RNC ID; the S-RNTI represents the radio network temporary identifier of the SRNC. SRNCidentity is defined as 12 bits, and thus the number of users supported by one RNC is 100 ten thousand. However, a large number of MTC devices require hundreds of RNCs to support.
Although the number of connections of the MTC devices is very large, the Average earnings per User (ARPU) is very low, so the operator does not want to spend excessive costs. According to the conventional method for allocating the MTC device identifiers, the number of the MTC devices supported by one RNC is not enough to meet the rapid development of the MTC devices, and the cost of network expansion is inevitably brought.

When the MTC device needs to initiate an MTC service, an RRC connection request is first sent to a network side, such as an RNC, where the RRC connection request carries MTC device indication information, and the RNC learns that the user equipment is an MTC device according to the MTC device indication information. Such as: the MTC equipment indication information is established for the following reasons: delay tolerant access (delay tolerant access) or small data indication (small data indication); the RNC knows that the request is the MTC service according to the establishment reason, and the terminal initiating the request is the MTC equipment naturally.
Step 101: and allocating the MTC equipment identification to the MTC equipment according to a preset MTC equipment identification allocation strategy.
The MTC equipment identity allocation strategy comprises the following steps: setting an N-bit identifier, wherein N bit represents the equipment identifier of the MTC equipment, and the value of the N bit is opposite to that of the N bit of the existing SRNC ID, namely, the N bit of the existing SRNC ID is not operated; the remaining (N-N) bits serve as the radio network temporary identifier of the MTC device. Wherein N is more than or equal to 1 and less than 12, and N is more than or equal to 32. In particular, the amount of the solvent to be used,
the UE identifier of 32 bits (bit), that is, N is 32, and optionally N bits in 12 bits corresponding to its SRNC ID are used as the device identifier for indicating that the UE is an MTC device, and the value of the N-bit device identifier is opposite to that of the corresponding bit of the SRNC ID; the remaining (32-n) bits are used to represent the wireless network temporary identity of the MTC device. Wherein n is more than or equal to 1 and less than 12.
The MTC device identifier allocation policy may also be that a new identifier is defined, where N is 32 bits, and if N is 32 bits, the operation that N bits of the new identifier and N bits of the current SRNC ID are negative is taken to indicate that the new identifier is the device identifier of the MTC device; the remaining (32-n) bits serve as radio network temporary identifications of the MTC devices. Wherein n is more than or equal to 1 and less than 12.
The step also includes that the network side, such as the RNC, can return the allocated MTC device identifier to the MTC device via an RRC connection establishment message. Thus, the MTC device stores the MTC device identifier, and then carries the MTC identifier when interacting with the RNC, so that the RNC can distinguish the terminal, and the MTC device is correspondingly processed.
In the method, the number of bits of the wireless network temporary identifier used for representing the MTC equipment is increased, so that the number of the MTC user equipment supported by one RNC is increased, the network deployment cost of an operator is reduced, and unnecessary network expansion expense is avoided.

It should be noted that the MTC service is all small data packets and has a low requirement on time delay, and in the present invention, the MTC service is carried by using a common channel, which saves resources and provides system capacity. Furthermore, the MTC devices are not moved or moved at a low speed, and therefore, it is not necessary to support handover and switching to a dedicated channel, and therefore, in order to simplify the procedure, the MTC devices may not be required to perform measurement. Then, after the MTC device switches in the cell and the service resource is successfully established, the RNC does not need to send a measurement control message to the MTC device.
