Description

A method and device for identifying grouped MTC equipment

technical field

The invention relates to the grouping technology of Machine Type Communication (MTC) equipment in the communication field, in particular to a method and device for identifying grouped MTC equipment.

Background technique

As a key technology of the machine-to-machine (M2M, Machine to Machine) Internet of Things system, machine-type communication (MTC, Machine-Type Communications) has become an important research topic at present. According to the definition given by relevant research institutions, MTC is a data communication involving one or more network entities that do not require manual intervention. MTC is based on a general-purpose telecommunication network, and has important application prospects in the fields of security, tracking, measurement, medical treatment, remote maintenance and control.

However, the introduction of the MTC system in the operator's network often means that a large number of communication terminals will be added to the network, that is, various MTC devices, such as sensors, controllers, etc., which will inevitably lead to a large number of resources in the network being occupied by MTC devices ; In addition, excessive signaling interaction may also cause network congestion. In order to solve these problems, existing research institutes propose that MTC devices can be grouped, that is, MTC devices belonging to the same user and having certain characteristics are classified into a group (Group). In this way, the network can control, manage, or charge the MTC devices in units of groups, thereby reducing many repeated signaling interactions and saving network resources.

To deal with grouped MTC devices, the network must first know how these devices are grouped, that is, to determine which devices belong to a group. This requires the MTC device itself to carry a certain identifier, and at the same time, devices belonging to the same group should carry a unified identifier that can be distinguished from other devices. However, there is no method in the prior art that can effectively identify the grouped MTC devices, so that the grouped MTC devices cannot be identified during the M2M communication process.

detailed description

The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

The present invention provides a method for identifying group-type MTC equipment, so that the network can determine the MTC equipment belonging to a certain group through the identification. The identification method of the present invention, in the International Mobile Subscriber Identity code (IMSI, InternationalMobileSubscriberIdentity) and Mobile Station Integrated Services Digital Network Number (MSISDN, Mobile-StationInternationalIntegrated-Services-Digital-NetworkNumber) commonly used by MTC equipment, is new for packet type MTC equipment Add group code (GC, GroupCode), specifically:

In the number field of the mobile subscriber identification number (MSIN, MobileSubscriberIdentificationNumber) identified by the IMSI, select a number of digits as the group identifier of the grouped MTC device, which is called the IMSI group code (IGC, IMSIGroupCode);

In the digit field of Subscriber Number (SN, SubscriberNumber) identified by MSISDN, several digits are selected as the group identifier of the grouped MTC device, which is called MSISDN Group Code (MGC, MSISDNGroupCode).

Of course, the group code (GC), IMSI group code (IGC) and MSISDN group code (MGC) in the present invention can also be taken as other names. Limitation of the scope of protection.

In fact, the common IMSI and MSISDN are still used as the identification of the grouped MTC device in the present invention, but some digits in these two identifications are endowed with new meanings, that is, used to indicate a specific group.

For the embodiment of adding an IGC for a packet-type MTC device in the IMSI, the structural diagram of the IMSI identifier is shown in FIG. 1 , which is also the current general IMSI identifier structure. The ID consists of three numeric fields:

Mobile Country Code (MCC, MobileCountryCode): used to uniquely identify the country to which the mobile user belongs;

Mobile Network Code (MNC, MobileNetworkCode): used to identify the mobile user's belonging public land mobile communication network (PLMN, PublicLandMobileNetwork);

Mobile Subscriber Identification Number (MSIN, MobileSubscriberIdentificationNumber): used to identify the mobile subscriber within the scope of the above-mentioned PLMN network.

In the above three digit fields, MCC and MNC have been endowed with specific meanings, that is, to indicate the location and network of the user or device. The present invention processes the MSIN digit field, that is, selects several digits in the MSIN as the group code of the grouped MTC device to identify the group to which the MTC device belongs.

In practical applications, the first few digits of the MSIN can be used as an independent digital field, as the IGC of the group, as shown in Figure 2; Several digits are combined as a group IGC, as shown in Figure 3.

Regardless of the solution shown in FIG. 2 or FIG. 3 , the network entity must know the IGC of the MTC group and the digit of the IGC in the MSIN when parsing the IMSI of the MTC device. In addition, the current relevant research institutes stipulate that the equipment of the same MTC group belongs to the same subscriber. Therefore, when the network identifies the MTC group according to the IMSI, it should analyze and identify the IMSI with the specific MCC and MNC. . Obviously, for any device in the network (not only MTC devices), as long as its IMSI contains a set of digits that match the IGC of a certain MTC group and also distribute the same digits as the IGC in MSIN, while its MCC and The MNC is the same as the MTC group device, so the network entity will regard this device as belonging to the MTC group. Therefore, when selecting the IGC code for the MTC group and the digits it occupies in the IMSI, and when assigning the IMSI to other devices (ie, non-packet MTC devices), care must be taken not to allow the network to misjudge an unrelated device To belong to a certain MTC group.

It can be seen that, in order to reduce the occupation of IMSI resources by the MTC group, the length of the IGC code should be as long as possible. For example, if the network setting MSIN is 10 digits, and a certain MTC group contains 75 devices, then the IGC of this group should be 8 digits, because in this way, all devices with the same MCC, MNC and IGC (and in There will be 100 IMSIs with the same digit), and these 100 IMSIs will only be used by this MTC group, which can accommodate 75 devices in the group; if the IGC of the group is reduced to 7 digits, There will be 1000 IMSIs with the same MCC, MNC and IGC (and in the same digit), that is to say, this group will occupy 1000 IMSIs, and only 75 of them will be used, which will obviously cause IMSI resources serious waste.

For the embodiment of adding an MGC for a packet-type MTC device in the MSISDN, the structural diagram of the MSISDN identifier is shown in FIG. 4 , which is also a common MSISDN identifier structure at present. The ID consists of three numeric fields:

Country code (CC, CountryCode): used to identify the country where the terminal is registered;

National Access Code (NDC, NationalDestinationCode): used to identify a numbering area or a network in a country;

Subscriber number (SN, SubscriberNumber): used to identify the mobile terminal within the above-mentioned numbering area or network range.

In the above three digit fields, CC and NDC have been designated to indicate the location or network of the user or device. The present invention processes the SN number field, that is, selects several digits in the SN as the group code of the grouped MTC device to identify the group to which the MTC device belongs.

In practical applications, the first few digits of SN can be used as an independent digital field, as a group MGC, as shown in Figure 5; it is also possible to use any number of digits in SN according to the current allocation of SN resources in the network Combined as a group of MGCs, as shown in Figure 6.

Regardless of the solution in Figure 5 or Figure 6, when the network entity resolves the MSISDN of the MTC device, it must know the MGC of the MTC group and the digit of the MGC in the SN. In addition, the current relevant research institutions stipulate that the devices of the same MTC group belong to the same subscriber. Therefore, when the network identifies the MTC group based on the MSISDN, it should analyze and identify the MSISDN with a specific CC and NDC. . Obviously, for any device in the network (not only the MTC device), as long as its MSISDN contains a set of digits that match the MGC of a certain MTC group and also distribute the same digits as the MGC in the MSISDN, while its CC and The NDC is the same as the device in the MTC group, so the network entity will regard this device as belonging to the MTC group. Therefore, when selecting the MGC code and its digits in the MSISDN for the MTC group, and when assigning the MSISDN to other devices (i.e., non-packet MTC devices), care must be taken not to allow the network to misjudge an irrelevant device To belong to a certain MTC group.

It can be seen that, in order to reduce the occupation of MSISDN resources by the MTC group, the length of the MGC code should be as long as possible. For example, if the network setting SN is 10 bits, and a certain MTC group contains 75 devices, then the MGC of this group should take 8 bits, because in this way, all devices with the same CC, NDC and MGC (and in There will be 100 MSISDNs with the same digit), and these 100 MSISDNs will only be used by this MTC group, which can accommodate 75 devices in the group; if the MGC of this group is reduced to 7 digits, There will be 1000 MSISDNs with the same CC, NDC and MGC (and in the same digit), that is to say, this group will occupy 1000 MSISDNs, and only 75 of them will be used, which will obviously cause MSISDN resources serious waste.

On the basis of the above-mentioned method for identifying a grouped MTC device, the present invention also provides a method for identifying a grouped MTC device, as shown in FIG. 7 , which mainly includes the following steps:

In step 701, the network entity performing device identification acquires the IMSI or MSISDN of the packet-type MTC device.

Step 702: Analyze the obtained IMSI or MSISDN to obtain the group code of the packet-type MTC device, and identify the group to which the packet-type MTC device belongs according to the group code.

Currently, relevant research institutes stipulate that devices in the same MTC group belong to the same subscriber. Therefore, when the network identifies an MTC group based on the IMSI, it should analyze and identify the IMSI with a specific MCC and MNC. Obviously, for any device in the network (not only MTC devices), as long as its IMSI contains a set of digits that match the IGC of a certain MTC group and also distribute the same digits as the IGC in MSIN, while its MCC and The MNC is the same as the MTC group device, so the network entity will regard this device as belonging to the MTC group.

Similarly, when the network identifies the MTC group according to the MSISDN, it should analyze and identify the MSISDN with the specific CC and NDC. Obviously, for any device in the network (not only the MTC device), as long as its MSISDN contains a set of digits that match the MGC of a certain MTC group and also distribute the same digits as the MGC in the MSISDN, while its CC and The NDC is the same as the device in the MTC group, so the network entity will regard this device as belonging to the MTC group.

When analyzing the IMSI of the MTC device, the network entity must predict the IGC of the MTC group and the digit of the IGC in the MSIN, so as to obtain the IGC from the correct location and identify the group to which the packet-type MTC device belongs. After the network entity obtains the IGC of the packet-type MTC device, it compares the obtained IGC with the information of the IGC stored by the network entity itself, and then identifies the group to which the packet-type MTC device belongs according to the comparison result. Of course, the premise of these operations is that the network entity must know the country and network to which the MTC group belongs, that is, the values of MCC and MNC.

Similarly, when analyzing the MSISDN of the MTC device, the network entity must predict the MGC of the MTC group and the digit of the MGC in the MSISDN, so as to obtain the MGC from the correct position and identify the group to which the packet-type MTC device belongs. Group. After the network entity obtains the MGC of the packet-type MTC device, it compares the obtained MGC with the information of the MGC stored by the network entity itself, and then identifies the group to which the packet-type MTC device belongs according to the comparison result. Of course, the premise of these operations is that the network entity must know the country and network to which the MTC group belongs, that is, the values of CC and NDC.

Corresponding to the above identification method for grouped MTC devices, the present invention also provides an identification device for grouped MTC devices, including: an identification code acquisition unit and a group identification unit. Wherein, the identification code obtaining unit is used to obtain the IMSI or MSISDN of the packet-type MTC device. The group identification unit is used to analyze the obtained IMSI or MSISDN to obtain the group code of the grouped MTC device, and combine the MCC and MNC number fields in the IMSI or the CC and NDC numbers in the MSISDN at the same time according to the group code segment, identifying the group to which the grouped MTC device belongs.

It should be noted that the group code can be located in the MSIN number field of IMSI, occupying the first few digits or any number of digits in the MSIN number field; it can also be located in the SN number field of MSISDN, occupying the first few digits of the SN number field digits or any number of digits.

To sum up, through the present invention, there is no need to make major changes to the existing identification system of the network, and it is not necessary to modify the network architecture. Instead, it is only necessary to slightly strengthen the functions of the network The group code (IGC or MGC) in to determine the group to which the MTC device belongs.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
