The technical solutions of the present invention are further elaborated below in conjunction with the accompanying drawings and specific embodiments. A method for identifying an M2M terminal provided by the present invention, as shown in FIG. 2, mainly comprises the following steps:

Step 201: The M2M terminal sends control signaling or service data to the base station, where the control signaling and the service data carry the identifier information and/or capability information of the M2M terminal.

The so-called M2M terminal sends service data to the base station, that is, an M2M terminal sends the collected service data to the base station at a specified time, for example: an M2M terminal meter device in a remote meter reading system, and the user who sends the record on the last day of the specified month. The electricity is recorded to the network server. Since the service data needs to be transmitted through the mobile communication network, the M2M terminal needs to send the collected service data to the base station.

The M2M terminal carries its own identification letter in the message that sends the service data to the base station. Interest, and in the process of initially assigning the terminal identifier, the ordinary mobile terminal and the M2M terminal can be distinguished in various ways as follows:

1. When an International Mobile Subscriber Identity (IMSI, International Mobile Subscriber Identity) or an International Mobile Equipment Identity (IMEI) is used as the identifier of the terminal, only a part of the allocation is allocated from the allocation range of the IMSI and the IMEI. The M2M terminal is used to identify the M2M terminal. Currently, IMSI has a total of 15 digits, and its structure is: 3-digit Mobile Country Code + 2 mobile network code (MNC, Mobile Network Code) + 10-digit mobile subscriber identity (MSIN, Mobile Subscriber Identification Number ), then the distinction between the common terminal and the M2M terminal is only possible through the MSIN. The specific segment dedicated to the M2M can be preset according to the demand of the local M2M terminal. Then, if the MSIN carried in the message for transmitting the service data belongs to a preset number segment, it indicates that the terminal that sends the service data is the M2M terminal; otherwise, the terminal that sends the service data is the ordinary mobile terminal.

The IMEI consists of 15 digits, and its composition is: The first 6 digits are the model approval number (TAC, Type Approval Code), which represents the model; the next 2 digits is the final assembly number (FAC, Final Assembly Code), representing the origin The next 6 digits are the serial number (SNR, Serial Number), which represents the production sequence number; the last 1 digit is the check code (SP, Spare Number), which is usually 0, and is currently reserved. Therefore, the normal mobile terminal and the M2M terminal can be distinguished by the TAC, for example: setting a specific TAC value to be represented as an M2M terminal, and if the TAC carried in the message for transmitting the service data by the terminal is the specific value, indicating that the service data is sent The terminal is an M2M terminal; otherwise, the terminal indicating that the service data is transmitted is an ordinary mobile terminal.

2. When using Evolved Absolute Radio Frequency Channel Number (EARFCN) + Cell Physical Layer Identity (C-RNTI, Cell Radio Network Temporary Identity) When it is used as the identifier of the terminal, it is divided into a part of the allocation range of the C-RNTI. Assigned to the M2M terminal, the C-RNTI uniquely identifies one terminal within the cell range. The C-RNTI is a 16-bit ID. It can allocate the appropriate range to the M2M terminal according to the service of the local M2M terminal. For example: The reserved segment with the value equal to 1~100 is used by the M2M terminal. The terminal can only allocate more than 100 values. If the value of the C-RNTI carried in the message that the terminal sends the service data belongs to 1 to 100, the terminal that sends the service data is the M2M terminal. The value of the C-RNTI carried in the value is greater than 100, indicating that the terminal that sends the service data is an ordinary mobile terminal.

3. When the PCI+C-RNTI is used as the identifier of the terminal, a part of the allocation range of the C-RNTI is allocated only to the M2M terminal, and the specific allocation manner is the same as the C-RNTI allocation manner in the second method. I won't go into details here.

4. When the C-RNTI is used as the identifier of the terminal, a part of the allocation range of the C-RNTI is allocated to the M2M terminal only. The specific allocation mode is the same as the C-RNTI allocation mode in the second mode. Let me repeat.

5. When (eNB UE SIAP ID) and/or (MME UE SIAP ID) are used as the identifier of the terminal, a part of the eNB UE SIAP ID and the MME UE S 1 AP ID are allocated only to the M2M terminal, and the eNB UE SIAP The ID uniquely identifies one terminal within the range of the base station, and the MME UE SIAP ID uniquely identifies one terminal within the scope of the mobility management entity. The eNB UE SIAP ID is an identifier of the terminal in the base station, and the MME UE SIAP ID is an identifier of the terminal in the Mobility Management Entity (MME), and the SIAP refers to an interface protocol between the base station and the MME.

The eNB UE SIAP ID and the MME UE SIAP ID may be allocated in the same manner as the C-RNTI. For example, the eNB UE may be reserved for the M2M terminal with the SIAP ID value of 1 to 100. If the value of the eNB UE's SIAP ID is 1 to 100, the terminal that sends the service data is the M2M terminal; if the terminal sends the service data, the message is carried in the message. of The value of the eNB UE's SIAP ID is greater than 100, indicating that the terminal that sends the service data is an ordinary mobile terminal. Similarly, the MME UE SIAP ID value equal to 1~100 can be reserved for the M2M terminal, and the normal mobile terminal can only allocate more than 100 values. Then, if the terminal sends the service data, the MME UE SIAP ID is carried in the message. If the value is 1 to 100, the terminal that sends the service data is the M2M terminal. If the value of the MME UE's SIAP ID is greater than 100, the terminal that sends the service data is the ordinary mobile terminal.

6, can also add additional identification, specifically for indicating the terminal type, for example: Increase the identification information "IsM2M", if the setting value of "IsM2M" is 1, it is expressed as M2M terminal; If the setting value of "IsM2M" is 0 Or not set, it is expressed as a normal mobile terminal. Then, if the setting value of "IsM2M" carried in the message for transmitting the service data by the terminal is 1, it indicates that the terminal transmitting the service data is the M2M terminal; otherwise, the terminal transmitting the service data is the ordinary mobile terminal.

The so-called M2M terminal sends control signaling to the base station, for example, an M2M terminal sends the collected service data to the base station at a specified time. Since the service data needs to be sent through the mobile communication network, the M2M terminal needs to send the connection request signaling to the base station. . The control signaling in the present invention is not limited to only one type of connection request signaling, and includes other control signals transmitted by the M2M terminal to the base station.

The M2M terminal carries the capability information in the control signaling sent to the base station, where the terminal that sends the control signaling is the M2M terminal. For example: Add an M2M Capability information element to the UE Capability, and set the value to True or False. Set to True to indicate that the terminal that sends the control signaling has the M2M capability and is the M2M terminal. Set to False to indicate that the terminal that sends control signaling does not have M2M capability and is an ordinary mobile terminal. Alternatively, the value of the M2M Capability may be set to a specific M2M capability, which respectively corresponds to different capabilities such as low mobility, low data volume, or time control, then when the control signaling is included in the packet When these M2M capabilities are included, they are represented as M2M terminals. When these M2M capabilities are not included in the control signaling, they are represented as ordinary mobile terminals.

Step 202: The base station identifies the M2M terminal according to the identification information and/or capability information of the M2M terminal.

The M2M terminal can be identified only according to the identification information of the M2M terminal; the M2M terminal can be identified only according to the capability information of the M2M terminal; and the M2M terminal can also be performed according to the identification information and capability information of the M2M terminal. Identification.

After receiving the message including the service data sent by the M2M terminal, the base station parses the identifier information of the terminal from the message, and according to the terminal identity allocation principle, determines that if the M2M terminal is, the received service data is transmitted to The core network is responsible for processing the entities of the M2M terminal, for example: transmitted to the m-MME, where the m-MME represents a core network entity dedicated to processing M2M service data.

After receiving the control signaling sent by the M2M terminal, the base station reads the information in the Capability of the UE, and determines whether the terminal that sends the control signaling is an M2M terminal according to the setting of the M2M Capability information element, and if so, the M2M The service data transmitted by the terminal in the subsequent transmission to the core network is responsible for processing the entity of the M2M terminal.

In addition, to implement the foregoing method for identifying an M2M terminal, the present invention further provides a system for identifying an M2M terminal, including: an M2M terminal and a base station. The M2M terminal is configured to send control signaling or service data to the base station, where the control signaling and the service data carry the identification information and/or capability information of the M2M terminal. The base station is configured to identify the M2M terminal according to the identification information and/or capability information of the M2M terminal.

When the identifier information of the M2M terminal is: IMSI or IMEI, the base station is further configured to identify the M2M terminal according to the IMSI or the IMEI in the identifier information.

When the identifier information of the M2M terminal includes: EARFCN, PCI, and C-RNTI, or includes PCI and C-RNTI, or is C-RNTI, the base station is further used according to the identifier information. The C-RNTI identifies the M2M terminal.

When the identifier information of the M2M terminal is: eNB UE S1AP ID and/or (MME UE S1AP ID), the base station is further configured to identify the M2M terminal according to the eNB UE S1AP ID and/or the MME UE S1AP ID in the identifier information.

When the identifier information of the M2M terminal is an additional identifier, the base station is further configured to identify the M2M terminal according to the additional added identifier in the identifier information.

When the capability information of the M2M terminal is the M2M capability information element, the base station is further configured to identify the M2M terminal according to the M2M capability information element in the capability information.

The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
