Description

Method for transmitting accident message, method and device for controlling multicast range The application claims to be submitted to the Chinese Patent Office on April 25, 2012, the application number is 201210123888.9, and the invention name is "a method for transmitting an accident message, and the control is more The priority of the Chinese Patent Application, which is incorporated herein by reference.

Technical field

The present invention relates to the field of network communication technologies, and in particular, to a method for transmitting an accident message, and a method and device for controlling a multicast range.

Background technique

As the Long Term Evolution (LTE) network is deployed more widely, it will enable many different machine-to-machine (M2M) communication scenarios, such as Intelligent Transportation Systems (ITS, Intelligent). Transport System) and some disaster monitoring warnings. In some M2M applications of accident alarms, once an accident occurs in a certain place, it is necessary to notify people around or avoid the car to avoid further losses.

For example, in the ITS, if the sensor of an in-vehicle UE detects an accident, if the incident is not serious, the UE reports the accident message to the eNB, and the eNB only needs to multicast the accident message to the UE within its control range. However, in some special cases, such as a major traffic accident, the accident message needs to be multicast not only to the in-vehicle UE within the control range of the local eNB, but also to notify the in-vehicle UE within the control range of the neighboring eNB. Even in the case where some accidents are particularly serious, the accident message needs to be notified to the in-vehicle UE within the control range of other eNBs with more than one hop range of the eNB.

In the prior art, the process of reporting and multicasting the accident message is: First, after detecting the event, the UE sends an accident message to the eNB of the local cell, and the eNB of the cell according to the severity of the accident, if the accident is not serious, the eNB only needs to take the accident. The message can be multicast to the UE within its control range. If the accident is serious, the event message is sent to the core network side (such as MME/S-GW);

The core network side determines which eNBs should be sent by the accident message according to the accident level, and then sends the office. The incident message, after receiving the accident message sent from the core network side, the eNB multicasts the accident message to the UE of the local cell.

In the research and practice of the prior art, the inventors of the present invention have found that in the existing implementation manner, although the forwarding of the accident message can be realized, the accident message needs to be forwarded to other eNBs through the core network, and the eNB The event message is transmitted to other UEs in the cell, which brings a relatively large delay, and cannot be quickly reported and multicasted.

detailed description

The technical solutions in the embodiments of the present invention will be described in detail with reference to the accompanying drawings. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative work are within the scope of the present invention.

In the embodiment of the present invention, the user equipment (UE, User Equipment) may be any one of the following, and may be static or mobile. The static UE may specifically be a terminal or a mobile station. ), a subscriber unit or a station, etc., the mobile UE may specifically include a cellular phone, a personal digital assistant (PDA), a wireless modem (modem), a wireless communication device, and a handheld device. The above-mentioned UEs may be distributed throughout the wireless network, such as a handheld computer, a laptop computer, a cordless phone, or a wireless local loop (WLL) station. Referring to FIG. 1 , FIG. 1 is a flowchart of a method for sending an accident message according to an embodiment of the present invention, where the method includes:

Step 101: Receive an accident message, where the accident message includes: a time to live (TTL) value corresponding to the severity level of the accident, and an accident information.

In this embodiment, there are two ways to receive an accident message: One is to receive the accident message reported by the user equipment UE, and the accident message includes a time-to-live TTL value corresponding to the severity level of the accident and the accident information.

That is, the manner in which the UE actively reports the incident message, that is, after the accident occurs, the UE reports an accident message to the local eNB (ie, the eNB on the incident side). The UE may report the TTL value set according to the fault level to the eNB. The TTL value and the transmission of the accident information in this embodiment may be performed by using a radio resource control (RRC) message, but is not limited thereto.

The TTL is the number of times the accident message can be forwarded. Generally, the TTL is set by the sending host (such as a user equipment or a base station, etc.) to control the number of times the data packet is forwarded. When the base station that receives the data packet forwards the data packet, it is required to decrement the TTL value by 1. When the TTL value is counted to 0, the base station decides to multicast the data packet locally. That is, when the TTL value is reduced to 0, the forwarding is stopped. In addition, the TTL can also be a certain time value. If the time value is 0, it will not be forwarded, and the packet will be multicast only locally.

The incident message is sent by the service server, and the accident message includes: a survival time TTL value corresponding to the severity level of the accident and the accident information. That is, after the accident occurs, the service server receives the accident information sent by the UE, and then the service server determines the severity level of the accident according to the accident information, thereby determining the corresponding TTL value, and then sending the TTL value to the service. eNB.

Step 102: Send the accident message to the neighboring base station eNB, so that the neighboring eNB multicasts the accident information, and determines whether the accident message needs to be forwarded according to the TTL value.

In this step, the accident message may be sent to an adjacent eNB through an X2 interface. In the embodiment of the present invention, the eNB of the accident side has a lifetime TTL value corresponding to the severity level of the accident. And the accident information is sent to the neighboring eNB, so that the neighboring eNB multicasts the accident information, and determines whether the accident message needs to be forwarded according to the TTL value. That is, after receiving the incident message, the eNB on the incident side does not forward the error message to other eNBs through the core network side, but directly forwards the accident message to the eNB adjacent thereto, and indicates whether the neighboring eNB needs to forward the device. The accident message realizes the fast and flexible control of the multicast range of the accident message and reduces the time for the accident message to be forwarded.

Further, in the embodiment of the present invention, the incident side eNB may send an accident message including the TTL value and the accident information to the neighboring eNB through the X2 interface, that is, use a special field in the message through the X2 interface to indicate whether the neighboring eNB is The message needs to be multicast only within the control range of the eNB, or the event message needs to be forwarded to its neighboring eNB, and the message needs to be multicast within the control range of the eNB.

Optionally, in order to prevent the neighboring eNB that has received the incident message from repeatedly transmitting the same incident message, after sending the incident message to the neighboring eNB, the method may further include: if receiving within the set time The incident message sent by the neighboring eNB does not forward and multicast the accident message sent by the neighboring eNB. For example, if the eNB receives an accident message transmitted by an adjacent eNB within a set time window after transmitting the accident message, the eNB does not repeatedly forward the received accident message.

Optionally, in this embodiment, in order to avoid unnecessary accident messages transmitted between adjacent eNBs, a newly received accident message is not missed, and the foregoing is sent to the neighboring eNB. In addition to the TTL value and the accident information, the accident message may further include: a sequence number SN of the accident message, which is set by the fault side eNB.

Optionally, in this embodiment, in order to prevent the accident message sent from two different eNBs from being confused, so that some accident messages are not forwarded, in addition to the accident message sent to the neighboring eNB The TTL value and the accident information may also include: an accident eNB ID, and an SN corresponding to the accident eNB ID.

Optionally, in this embodiment, if the accident information includes geographical location information, The eNB of the accident message can further determine which neighboring eNBs need to be forwarded to the neighboring eNBs within a preset range, and the neighboring eNBs that are not within the preset range do not need to forward the accident message.

That is to say, in this embodiment, the accident information mainly includes some parameters describing the accident, and may also include information such as geographic information. The eNB that receives the accident message can determine the neighboring eNBs to which the accident message should be forwarded according to the TTL and the geographic information. For example, although some eNBs are neighboring eNBs, but they are not within the preset range, No forwarding.

Referring to FIG. 2, FIG. 2 is a flow chart of a method for controlling a multicast range according to an embodiment of the present invention, where the method includes:

Step 201: Receive an incident message sent by the neighboring base station eNB, where the accident message includes: a survival time TTL value and an accident information corresponding to the severity level of the accident;

Step 202: Determine whether the TTL value is greater than a preset value, if it is greater, perform step 203; if equal, perform step 204;

Step 204 is an optional step. The preset value may be set to 0, where 0 indicates that the hop count is 0, and may be a certain time value. The preset value in this embodiment is set to 0 hop as an example. ;

Step 203: multicast the accident information within a controlled range, and decrement the TTL value by 1; and forward the accident message including the new TTL value to the adjacent eNB;

Step 204: Multicast the accident information within a controlled range.

In the embodiment of the present invention, the multicast range of the accident message can be quickly and effectively controlled.

The present invention provides a method for controlling a multicast range. The eNB determines whether to multicast the accident information within a controlled range according to a TTL value, or needs to forward the accident message to other neighboring eNBs to facilitate neighboring. The eNB makes further judgments. Thereby, the multicast range of the accident message is quickly and flexibly controlled, and the time of the accident message forwarding is reduced.

Optionally, in order to prevent the neighboring eNB that has received the accident message from repeatedly transmitting the same incident message, after the step 203 or the step 204, the method may further include: if the time is within the set time After receiving the incident message sent by the neighboring eNB, the accident message sent by the neighboring eNB is not forwarded and multicasted.

Optionally, in order to avoid receiving the incident message neighboring eNB, sending the accident message to the source eNB of the accident message, after receiving the incident message sent by the neighboring base station eNB, the method may further include: determining whether to The source eNB of the incident message sends the accident message. If it is not sent, step 202 is performed to determine whether the TTL value is greater than a preset value, and a subsequent step.

Optionally, in order to avoid unnecessary accident messages transmitted between neighboring eNBs, a newly received accident message is not missed, and if the received accident message further includes the sequence number SN of the accident message, The method may further include: determining whether the sequence number SN of the accident message has been received, and if not, performing step 202, that is, determining whether the TTL value is greater than a preset value, and subsequent steps.

Optionally, the accident message sent from two different eNBs is confused, so that some accident messages are not forwarded, and if the received accident message further includes an accident eNB ID and a sequence number of the corresponding accident message. SN, the method may further include: determining whether the eNB ID and the sequence number SN of the accident message corresponding to the eNB ID are received, and if not, performing step 202, determining whether the TTL value is greater than a preset. The steps of the value, and its subsequent steps.

Optionally, in all the foregoing embodiments, the eNB that receives the incident message may further determine, in order to further forward the incident message to the neighboring eNBs, if the incident information includes geographical location information, the method may further The method includes: determining, according to the geographic location information, a neighboring eNB that is in a preset range of the neighboring eNB, and the forwarding the incident message to the neighboring eNB specifically includes: forwarding the accident message to the advance Set the eNB within the range.

That is to say, in this embodiment, in the process of forwarding the incident message including the new TTL value to the neighboring eNB, which neighboring eNBs are specifically forwarded, the geographic information may be used to determine whether the event needs to be forwarded. Messages, before forwarding, you can first determine which neighbors are based on geographic information. The eNB is within a preset range, after which the eNB forwards an accident message including a new TTL value to a neighboring eNB within the preset range; for neighboring eNBs that are not within the preset range, the eNB does not need to forward.

That is to say, in this embodiment, the accident message may include at least one of the following: in addition to the TTL value and the accident information: the accident eNB ID and the accident message sequence number SN.

The embodiment of the present invention further provides a method for controlling a multicast range, where the method includes: receiving an accident message sent by a user equipment UE, where the accident message includes a flag of an event severity level;

Determining, according to the flag of the severity level of the event, a time-to-live TTL value corresponding to the severity level of the event; determining whether the TTL value is greater than a preset value, and if greater than, multicasting the accident information within a controlled range, and The TTL value is decremented by 1, and the incident message including the new TTL value is forwarded to the neighboring eNB.

The implementation process of the method is different from the implementation process of the foregoing method, in that the eNB receives the event message sent by the user equipment only includes the flag of the event severity level, and the eNB needs to determine the event severity level according to the flag of the event severity level. The corresponding TTL value of the time-to-live is the same as the above method. For details, refer to the above, and details are not described herein. That is to say, the UE may also report a predetermined event severity level flag to the eNB, and then the eNB sets the TTL value according to the severity level.

In order to facilitate the understanding of those skilled in the art, the following is a specific application example.

Embodiment 1

FIG. 3 is a flowchart of a first application example of a method for controlling a multicast range according to an embodiment of the present invention. In this embodiment, after the TTL value is known, the eNB on the incident side passes the X2 interface. Sending an accident message including a TTL value to an adjacent eNB. After receiving the accident message, the neighboring eNB determines whether it needs to be forwarded according to the TTL value. As shown in FIG. 3, after the neighboring eNB sends an accident message to the eNB, the neighboring eNB receives other neighboring eNBs. After the incident message is sent, it specifically includes:

Step 301: The eNB receives an incident message sent by the neighboring eNB (the neighboring eNB, which may be an affiliation eNB, or another neighboring eNB, which is not limited in this embodiment), and the incident message includes: The TTL value and the accident information corresponding to the severity level; the accident message in this embodiment takes the TTL value and the accident information as an example.

In this embodiment, the eNB may receive an accident message sent by the neighboring base station eNB through the X2 interface.

Step 302: The eNB determines whether the TTL value is greater than 0, if greater than 0, performing step 303 and step 305; if equal to 0, performing step 304 and step 305;

Step 303: The eNB multicasts the accident information in the local cell, and decrements the TTL value by 1, and forwards an accident message including a new TTL value to an adjacent eNB.

Step 304: The eNB multicasts the accident information in the local cell.

Step 305: End the process.

In this embodiment, a format of the accident message sent through the X2 interface is as follows: including: message type, TTL, and even information, as shown in the specific chart 1:

Table 1

Hessage Ty e TTL Event information In the accident message, the Message Type is a field that all messages in the X2 interface must have, which is used to identify the type of the message.

Embodiment 2

An advantage of the method described in the first embodiment is that the implementation is simple. The eNB only needs to determine the value of the TTL to perform the corresponding action. Its disadvantage is that there are many unnecessary transmissions between adjacent eNBs.

In the second embodiment, the eNB that has received the accident information may be avoided in the foregoing embodiment. The same accident information is repeatedly transmitted, and the specific implementation manner is as follows: After step 303 and step 304, if the eNB receives an accident message transmitted by another eNB within a set time window after the event message is sent, the eNB The accident message is not repeatedly transmitted, and the accident information is not multicast in the cell. The format of the accident message sent in this embodiment is the same as the format of the accident message of the embodiment. For details, refer to the above.

Embodiment 3

The content and format of the accident message in the third embodiment are the same as the content and format of the accident message in the second embodiment, except that the eNB determines whether the mechanism for forwarding the accident message is different. That is, since the eNB of the X2 interface knows the ID number of the neighbor eNB, in order to avoid the eNB receiving the accident message, the event message is sent to the source eNB of the accident message, and after the eNB receives the accident message, Determining whether the accident message is sent to the source eNB of the accident message. If it is determined that an accident message has been sent to the source eNB of the accident message, the eNB does not process; otherwise, the method is processed according to the first embodiment. That is, the step of determining whether the TTL value is greater than a preset value, and subsequent steps thereof are performed.

Embodiment 4

The fourth embodiment is to further reduce unnecessary accident messages transmitted between the eNBs in the second embodiment and the third embodiment. That is to say, in the case that the eNB has multiple accident messages, the second embodiment and the third embodiment may cause the eNB not to forward the newly received accident message. Therefore, in the technical solution of the fourth embodiment, unnecessary accident messages are transmitted between adjacent eNBs, and a newly received accident message is not missed. The specific implementation method is as follows: The sequence number SN of the accident message, such as the accident 1, the accident 2, and the like, is added to the accident message passing through the X2 interface. That is, the accident message includes: SN, TTL, and accident information, that is, the accident message includes these three parameters as an example. The SN is set by the eNB of the accident occurrence cell, and other eNBs that receive the accident message do not change the SN value when forwarding the accident message. Specifically, as shown in FIG. 4, FIG. 4 is a flowchart of a second application example of a method for controlling a multicast range according to an embodiment of the present invention, where: Step 401: The eNB receives an incident message sent by an adjacent eNB. The incident message includes: a TTL value, an accident information, and a sequence number SN of the accident message.

Step 402: The eNB determines whether the sequence number SN of the accident message is received. If not, step 403 is performed; otherwise, step 406 is performed;

In this step, one of the judgment manners is: comparing the received SN with the stored previously received SN, if there is the same, it indicates that the SN has been received, otherwise, there is no Received the SN. Of course, the embodiment is not limited to this determination manner, and may be other determination methods.

Step 403: The eNB continues to determine whether the value of the TTL in the accident message is greater than 0. If it is greater than 0, perform step 404 and step 406; if equal to 0, perform step 405 and step 406;

Step 404: The eNB multicasts the accident information in the local cell, and decrements the value of the TTL by 1, and sends an accident message including the new TTL value to the neighboring eNB.

Step 405: The eNB multicasts the accident information only in the local cell.

Step 406: Ignore the accident message.

The format of the accident message passing the X2 interface in this embodiment is shown in Table 2:

Table 2

Embodiment 5

Although the method described in Embodiment 4 above can solve the problem that a single eNB sends an accident message, in some special cases, an accident message may occur under multiple eNBs. In this way, the accident message is initiated on multiple eNBs. In this embodiment, the accident messages sent from two different eNBs are confused in order to avoid forwarding, so that some accident messages are not forwarded. In the fifth embodiment, the accident eNB ID, the SN, the TTL, and the accident information are added to the accident message. Specifically, as shown in FIG. 5, FIG. 5 is a third application example of a method for controlling a multicast range according to an embodiment of the present invention. The flow chart specifically includes: Step 501: The eNB receives an incident message sent by the neighboring eNB. The incident message includes: an eNB ID, an SN, a TTL, and an accident information.

Step 502: The eNB determines whether the eNB ID and the sequence number SN of the incident message corresponding to the eNB ID are received. If not, step 503 is performed; otherwise, step 506 is performed;

In this step, the way of judging can be compared with the stored ones. If they are the same, it means that they have been received, otherwise, they have not received them. This embodiment is not limited to this manner.

Step 503: The eNB continues to determine whether the value of the TTL in the accident message is greater than 0. If it is greater than 0, perform step 504 and step 506; if equal to 0, perform steps 505 and 506;

Step 504: The eNB multicasts the accident information in the local cell, and decrements the value of the TTL by 1, and sends an accident message including the new TTL value to the neighboring eNB.

Step 505: The eNB multicasts the accident information only in the local cell.

Step 506: Ignore the accident message.

The format of the accident message passing the X2 interface in this embodiment is shown in Table 3:

table 3

Embodiment 6

In the above-mentioned Embodiments 1 to 5, the accident message carries an Event information field, which is mainly used to transmit some parameters describing the accident, such as geographic information. The eNB receiving the accident message including the accident information can determine which eNB the accident message should be forwarded to in combination with the TTL and the geographic information. For example, some eNBs are adjacent but not within the preset range. For example, the eNB determines, according to the geographical location information, which of the neighboring eNBs are within a preset range; and then determines whether the TTL value is greater than a preset value, and if it is greater than, the eNB is in the current cell. The accident information is multicast, and the TTL value is decremented by 1, and an accident message including a new TTL value is forwarded to a neighboring eNB that is preset.

Of course, it is also possible to first determine whether the TTL value is greater than a preset value, and then according to the geographical location. The information is judged by the neighboring eNBs, which are within a predetermined range; finally, the accident message including the new TTL value is forwarded to the neighboring eNBs within the preset range.

Based on the implementation process of the foregoing method, the embodiment of the present invention further provides an apparatus for transmitting an accident message, and a schematic structural diagram thereof is shown in FIG. 6. The device includes: a receiving unit 61 and a sending unit 62, where

The receiving unit 61 is configured to receive an incident message, where the incident message includes: a survival time TTL value corresponding to the severity level of the accident and the accident information; the receiving unit may include: a first receiving unit and/or a second receiving unit, The first receiving unit is configured to receive the incident message reported by the user equipment UE, and/or the second receiving unit is configured to receive the incident message delivered by the service server, where the sending The accident message is: after receiving the accident information sent by the UE, the service server determines an accident message corresponding to the TTL value according to the severity level of the accident information.

The sending unit 62 is connected to the receiving unit 61, and configured to send the accident message to the neighboring base station eNB, so that the neighboring eNB multicasts the accident information within a controlled range, and according to the The TTL value determines whether the accident message needs to be forwarded. The sending unit 62 is specifically configured to send the accident message to the neighboring eNB through the X2 interface.

The incident message sent by the sending unit to the neighboring base station eNB further includes at least one of the following: an accident number sequence number SN and an accident eNB ID. The SN is set by the accident side eNB.

Optionally, the device may further include: a determining unit, configured to be connected to the sending unit, configured to determine, after the sending unit sends the accident message to an adjacent eNB, whether the phase is received within a set time The incident message sent by the neighboring eNB, if received, does not forward and multicast the accident message sent by the neighboring eNB.
