Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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.

An embodiment of the present invention provides a method for transmitting an M2M service message, as shown in fig. 1, an execution subject of the method is MTC (Machine Type Communications) adaptation equipment, and the method includes:

s101, the MTC adaptation equipment acquires a CoAP message and acquires first identification information in the CoAP message.

Specifically, the MTC adaptation device obtains the first identification information of the CoAP terminal in the CoAP message by analyzing the CoAP message.

It should be noted that the CoAP terminal may include a main terminal and at least one auxiliary terminal, where the main terminal supports 3GPP, the auxiliary terminal does not support 3GPP capability (for example, 3GPP service without SIM card), and the main terminal serves as a proxy terminal of the auxiliary terminal to relay a message, and of course, the CoAP terminal may also include only the main terminal.

For example, the MTC adaptation device may parse a Uri-Host field and a Proxy-Uri field in a CoAP message, thereby obtaining first identification information of the CoAP terminal; specifically, if there is no corresponding auxiliary terminal under the main terminal of the CoAP terminal, that is, there is no Proxy-Uri field in the CoAP message, only the Uri-Host field in the CoAP message is analyzed, so as to obtain the first identification information of the CoAP terminal, where at this time, the first identification information of the CoAP terminal may be the Host name of the CoAP terminal; if an auxiliary terminal is corresponding to the main terminal of the CoAP terminal, that is, a Proxy-Uri field exists in the CoAP message, a Uri-Host field and a Proxy-Uri field in the CoAP message are analyzed, and at this time, the first identification information of the CoAP terminal may be a Host name of the CoAP terminal and identification information of the auxiliary terminal transmitted by the CoAP message under the main terminal of the CoAP terminal.

Optionally, the MTC adaptation device receives a CoAP message sent by the CoAP server,

further, the CoAP server may further send a CoAP message to a TDF (Traffic detection function), so that after the TDF determines that the received message is the CoAP message, the MTC adaptation device receives the CoAP message sent by the TDF.

Specifically, the TDF detects that the received message includes a URL (Uniform Resource Locator) beginning with the map:// or maps:// and determines that the message is a CoAP message.

Optionally, in a scenario that a CoAP terminal supporting a CoAP protocol interacts with an HTTP server supporting an HTTP (hypertext transfer protocol), the MTC adapter device receives an HTTP message sent by an HTTP server, and therefore, the MTC adapter device needs to convert the HTTP message into a CoAP message after receiving the HTTP message.

The above conversion of the HTTP message into the CoAP message can be understood as follows: converting the message from HTTP format to CoAP format, for example: the URL beginning with http:// or https:// in the message may be modified to be the URL beginning with copa:// or cops:// here by way of example only and the invention is not limited thereto.

Further, after the TDF determines that the received message is an HTTP message and determines that the CoAP terminal supports CoAP service, the TDF receives the CoAP message sent by the TDF.

S102, the MTC adaptation equipment acquires the state information of the base station and determines the forwarding strategy of the CoAP message according to the first identification information and the state information.

Further, the MTC adaptation device may obtain status information of a base station from an MME (Mobility Management Entity) or a PDN (Packet Data network) gateway

The status information of the base station may be congestion information of the base station or load information of the base station.

For example, when the MTC adapter device obtains the destination base station of the CoAP message according to the first identifier information, and obtains the state information of the base station after receiving the CoAP message, it obtains that the destination base station is in an idle state or a congested state according to the state information of the base station, and if the destination base station is in an idle state, it determines to send the CoAP message to the destination base station; if the target base station is in the congestion state, the CoAP message is discarded or sent in a delayed mode, so that the forwarding of the CoAP message is controlled and managed, and the problems of network congestion and the like are avoided.

Specifically, before the status information of the base station is obtained, the MTC adapter receives the third identifier information of the base station sent by the HSS.

The third identification information of the base station is the information acquired by the HSS from the MME according to the stored second identification information of the MME;

and the MTC adaptation equipment acquires the state information of the base station according to the third identification information.

The third identification information may include:

E-UTRAN Cell Global Identity (E-UTRAN (Evolved Universal terrestrial radio Access Network)) Cell Global Identity, wherein the information refers to the latest serving Cell of the CoAP terminal;

the E-UTRAN Cell Identity Age is the time limit of the E-UTRAN Cell Identity, and the information refers to the time which elapses after the Cell global Identity is acquired.

Further, after determining to send the CoAP message according to the first identification information and the state information, the MTC adaptation device sends the CoAP message to the PDN gateway.

The MTC adaptation equipment sends application layer information to a PCRF (Policy and Charging Rules Function), so that the PCRF configures a control Policy according to the application layer information and the acquired first subscription information and second subscription information, and sends the control Policy to a PDN gateway, so that the PDN gateway sends the CoAP message to the CoAP terminal through the base station according to the control Policy after receiving the CoAP message sent by the MTC adaptation equipment.

The above control policy mainly includes that the PDN gateway sends the CoAP message according to a rule name, a service ID, a service data flow template, a gateway state, or a QoS parameter, which is not limited in the present invention.

It should be noted that before sending the CoAP message to the CoAP terminal through the base station, the PDN gateway also establishes or activates a bearer according to the control policy, so that the PDN gateway sends the CoAP message to the CoAP terminal through the base station.

Wherein the application layer information includes: bandwidth requirement information, application layer session related information, flow state information, priority indication information, emergency session indication information, application layer event identifier, and the like, which are not limited in the present invention.

The first subscription information includes: information such as location information of the CoAP terminal, authentication information of the CoAP terminal, service subscription information, etc., for example:

MPS EPS Priority, i.e. MPS (Multimedia Priority Service) EPS (Evolved Packet System), is preferred, and the information is used to indicate that the CoAP terminal signs to MPS in the EPS domain.

The EPS subscribed QoS profile is an EPS subscribed QoS attribute.

EPS PDN Subscribed Charging Characteristics.

Homography Support indication of the homography Support of the IMS Over PS session for MME, that is, IMS Over PS session, this information is used to indicate that the capability of the "IMS Over PS (IMS in PS domain)" can be equivalently supported (i.e., the same policy is adopted) in all TAs (Tracking areas) of the MME.

In this embodiment, the first subscription information further includes, in addition to the basic information: the application service provider of the CoAP terminal, the first identification information and the general identification of the equipment. The universal identification of the equipment is a preset identification which uniquely identifies one equipment.

The second subscription information includes: signing the service allowed by the user;

preemption priority for each service;

the QoS (Quality of Service) information allowed by the subscriber comprises parameters such as signed guaranteed bandwidth and the like;

charging-related information of the subscriber, such as location information and the like;

the type of the subscriber, etc.

Further, the acquiring, by the PCRF, the first subscription information includes the following two ways:

the first method is as follows: the MTC adapter equipment acquires the first subscription information of the CoAP terminal from an HSS (Home Subscriber Server) according to the first identification information.

Specifically, the MTC adapter device sends a query request message to the HSS, where the query request message includes the first identifier information, so that the HSS obtains the stored first subscription information of the CoAP terminal according to the first identifier information and sends the first subscription information to the MTC adapter device, and the MTC adapter device sends the first subscription information to the PCRF.

And the MTC adaptation equipment receives the first subscription information of the CoAP terminal sent by the HSS.

The HSS stores first subscription information of the CoAP terminal and second identification information of the MME.

The second method comprises the following steps: the MTC adaptation equipment sends the first identification information to the PCRF so that the PCRF can acquire first subscription information from the HSS according to the first identification information.

Specifically, after receiving the first identification information, the PCRF sends a query request message to the HSS, where the query request message includes the first identification information, so that the HSS obtains the stored first subscription information of the CoAP terminal according to the first identification information and sends the first subscription information to the PCRF.

It should be noted that the first and second manners are only two implementation manners provided in this embodiment, and the present invention is not limited thereto, and other manners capable of implementing that the MTC adapter device obtains the first subscription information should also be within the protection scope of the present invention.

Thus, the PCRF receives the first subscription information, and the first subscription information includes information such as location information of the CoAP terminal, authentication information of the CoAP terminal, service subscription information, and the like, so that the CoAP message transmission network can see the auxiliary terminal under the CoAP terminal main terminal for CoAP message transmission, and thus, policy and charging control can be performed on the CoAP message conveniently.

In addition, the MTC adaptation device determines a group corresponding to the CoAP message under the grouping rule according to the grouping determination information.

Wherein the packet determination message includes: and determining the group and a forwarding strategy of the CoAP message in the group according to the first identification information and the state information.

Specific grouping rules may include:

CoAP messages which come from the same application server and have the same service type and are transmitted to the same CoAP terminal form a group;

specifically, CoAP messages from the same application server and having the same service type and transmitted to the auxiliary terminals under the main terminal of the same CoAP terminal form a group;

or,

CoAP messages which come from the same application server, have the same service type and are transmitted to CoAP terminals with the same priority are grouped;

specifically, CoAP messages from the same application server and having the same service type and transmitted to the auxiliary terminals under the main terminals of CoAP terminals having the same priority are grouped;

or,

CoAP messages transmitted to the same base station form a group; or,

CoAP messages transmitted to the same CoAP terminal form a group; or,

CoAP messages transmitted to CoAP terminals with the same priority are grouped.

The MTC adapter device determines the group to which the CoAP message corresponds according to any one of the above grouping rules.

It should be noted that the grouping rule may be configured in advance, and the MTC adaptation device may determine the group corresponding to the CoAP message after receiving the CoAP message.

For example: the MTC adaptation device receives two CoAP messages (marked as CoAP message A and CoAP message B) at the same time, determines that the CoAP message A is transmitted to a target base station A and the CoAP message B is transmitted to a target base station B under the condition that the CoAP messages transmitted to the same base station are in a group as a grouping rule, divides the CoAP message A into the group A corresponding to the target base station A and divides the CoAP message B into the group B corresponding to the target base station B,

if the target base station A is in an idle state; when the target base station B is in a congestion state, the CoAP message in the group A is preferentially sent, and the CoAP message in the group B is discarded or sent in a delayed manner; on the contrary, the CoAP message in the group B is sent preferentially, and the CoAP message in the group A is discarded or sent in a delayed manner;

further, when determining to send the CoAP message in the group a, if the MTC adaptation device determines that too many CoAP messages in the group a exceed the maximum number that the target base station can bear, the MTC adaptation device may also determine, according to the priority message in the application layer of the CoAP message in the group a, the CoAP message that is preferentially sent in the same group.

It should be noted that, the group of CoAP messages transmitted to the same base station is used as the grouping rule for illustration only, and there are many specific grouping rules, which are not listed here, but all of which fall within the scope of the present invention.

Through the process of determining the group corresponding to the CoAP message, when the MTC adaptation device receives a large number of CoAP messages (for example, more than 100 messages) sent by the application server, the MTC adaptation device avoids the repetitive operation that the status information of the base station needs to be acquired every time one CoAP message is received, and can determine the forwarding strategy of the received CoAP message only by acquiring the status information of the base station once, thereby conveniently controlling and managing the received CoAP message.

Further, when the MTC adaptation device determines that the CoAP terminal supports the IMS service of the IP multimedia subsystem according to the first subscription information of the CoAP terminal, the MTC adaptation device converts the CoAP message into the IMS message.

Specifically, the above MTC adapter device converting the CoAP message into the IMS message may be understood as: the message is converted from CoAP format to IMS format.

In addition, if the CoAP terminal does not register the IMS service, the MTC adapter device also needs to trigger IMS registration of the CoAP terminal.

Furthermore, after determining to send the CoAP message according to the first identification information and the state information, the MTC adaptation device sends the IMS message to a call session control function CSCF, so that the CSCF converts the IMS message into session information and sends the session information to a PCRF, so that the PCRF configures a control policy according to the session information, first subscription information acquired from a subscription information server SPR and an HSS, and second subscription information acquired from the SPR, and sends the control policy to a PDN gateway, and the PDN gateway sends the IMS message received from the CSCF to the CoAP terminal through the base station according to the control policy.

Specifically, the CSCF converting the IMS message into session information may be understood as: and the CSCF acquires the information related to the application layer session corresponding to the message according to the IMS message.

By adopting the method for transmitting the M2M service message, the MTC adaptation equipment acquires the CoAP message, and can dynamically determine whether to forward the CoAP message according to the state information of the base station and the first identification information of the CoAP terminal through the acquired state information of the base station and the first identification information of the CoAP terminal, thereby realizing the control and management of the CoAP message in the transmission process.
