Description
Technical Field
The invention relates to a control technology in the field of mobile communication, in particular to an X2 interface message processing method, a base station, an X2 gateway and a system.
Background
A home base station in an lte (longtermsesolution) system defined by the third generation partnership project (3 GPP) standards organization is called henb (homeenb). The functions supported by the HeNB are basically consistent with the eNB, and the processes between the HeNB and the EPC (evolvedpacketcore) are basically consistent with those between the eNB and the EPC. The deployment of henbs is usually not planned by the mobile operator's network, and the coverage is small and numerous. For more convenient management and to support a larger number of henbs, under the E-utran (evoldcutran) architecture, a new network element henbgw (homeenbgaway) is introduced between the henbs and the S1 connection of the EPC. Since the number of usable X2 interfaces of a base station is limited, it is necessary to delete the unnecessary X2 connection relation in time so that the base station can establish a new X2 connection. Based on this requirement, an X2removal procedure is introduced into the X2 interface to remove the X2 connection between the two base stations. However, since the X2 gateway does not resolve the X2 message in the X2 interface information transfer message of its route, the X2 gateway cannot know that the X2 connection removal between the base stations is completed. Therefore, in the prior art, the X2 gateway cannot normally maintain the X2 connection information between its connected base stations, and when the X2 gateway detects that its SCTP connection with a certain base station is disconnected, it will send an unnecessary X2 release message to the neighboring base station that has removed the X2 connection with the base station and cause waste of X2 signaling.
In addition, after receiving the X2 interface procedure message, the X2 gateway may reply an error indication message to the base station if the received X2 interface procedure message cannot be processed correctly, for example, the routing cannot be correctly performed. A base station may initiate an X2 interface procedure to multiple neighboring base stations simultaneously through an X2 gateway.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The first embodiment,

step 101: receiving an instruction of an X2removal process message sent by a base station;
step 102: removing connection information of an X2 interface of a corresponding base station according to the X2removal process message.
Here, the X2removal procedure message includes at least one of: x2 remove request message, X2 remove response message, X2 remove failure message.
The received X2removal procedure message sent by the base station has two cases, one is a case where the X2removal procedure message is directly sent, and the other is a case where the X2removal procedure message is sent in an X2 interface information transmission message, which is specifically as follows:
the first condition is as follows: receiving an X2 interface information transmission message, and extracting an X2removal process message from the X2 interface information transmission message; wherein, the X2 interface information transmission message carries X2removal indication information; the X2removal indication information is used for indicating a message type contained in the X2 interface information transmission message or indicating information for controlling an X2 gateway to perform an X2removal operation; the message types include the following: x2 remove request message, X2 remove response message, X2 remove failure message.
In this case, the removing connection information of the X2 interface of the corresponding base station according to the X2removal procedure message includes:
receiving an X2 interface information transmission message, if the X2 interface information transmission message contains X2removal indication information, extracting carried identification information of a source base station and a target base station from the X2 interface information transmission message, and selecting and removing X2 connection relation information between the source base station and the target base station according to the identification information of the source base station and the target base station;
or,
after receiving an X2 interface information transmission message, if the X2 interface information transmission message contains X2removal indication information, extracting an X2 interface message from the X2 interface information transmission message, and when the X2 interface message is an X2removal response message, extracting identification information of a source base station and a target base station carried in the X2 interface information transmission message, and selecting and removing X2 connection relation information between the source base station and the target base station according to the identification information of the source base station and the target base station.
In case two, the X2 gateway receives the X2removal procedure message directly sent by the base station.
Wherein, the X2removal process message carries identification information of the target base station and/or the source base station.
Preferably, the method may further comprise: and when the X2removal response message is received, extracting the carried identification information of the source base station and the target base station from the X2removal response message, and selecting and removing the X2 connection relation information between the source base station and the target base station according to the identification information of the source base station and the target base station.
Further, the method further comprises: receiving an X2 interface message sent by a base station; the X2 interface message carries identification information of a target base station and/or a source base station; and when the X2 interface flow cannot be executed correctly, sending an error indication message to the base station, wherein the error indication message comprises the base station identification information of the source base station and/or the target base station.
The failure to correctly execute the X2 interface flow includes: the X2 interface message cannot be processed; alternatively, the X2 interface message cannot be routed.
The following describes the method provided in the present embodiment by way of a scenario.
As shown in fig. 2, the base station (eNB)1 and the base station (eNB)2 may be a home base station or a macro base station, and the method of X2removal is completed when an X2 connection is established between the base stations through an X2 gateway. The method specifically comprises the following steps:
step 201, the base station 1 and the base station 2 establish an X2 connection through an X2 gateway, and if the base station 1 detects that the X2 connection between the base station 1 and the base station 2 needs to be removed, an X2removal request message is sent to a connected X2 gateway, and the X2removal request message is not encapsulated in an X2AP message transfer message, but is directly sent to an X2 gateway.
Wherein, the X2 removes the base station identification information of the source and target base stations, i.e. the eNBID of base station 1 and base station 2, contained in the request message.
In step 202, the X2 gateway routes the X2 remove request message to the base station 2 according to the target base station id in the X2 remove request message sent from the base station 1.
In step 203, when the base station 2 determines to remove the X2 connection with the base station 1 according to the received X2removal request message, it replies an X2removal response message to the X2 gateway.
Wherein the X2removal response message is also not encapsulated in the X2AP messaging message, but is sent directly to the X2 gateway. The X2 removes the base station identification information of the source base station and the target base station contained in the response message.
And, the base station 2 may delete the X2 connection related information with the base station 1, and the X2 connection related information may include: resources, application layer configuration data.
In step 204, after receiving the X2removal response message, corresponding X2removal operation may be performed, that is, the X2 connection relationship information of the base station 1 and the base station 2 is deleted.
If the subsequent X2 gateway detects that the SCTP connection between the gateway and the base station 1 (or the base station 2) is disconnected, it will send an X2 release message to the base station with the X2 connection between the base station 1 (or the base station 2). Since the X2 gateway has deleted the X2 connection relationship information for base station 1 and base station 2, the X2 gateway does not send an X2 release message to base station 2 (or base station 1).
In step 205, the X2 gateway routes the X2 remove response message to base station 1 according to the target base station identity in the received X2 remove response message.
The information related to the X2 connection of the base station 2, such as resources, application layer configuration data, etc., may be deleted after the reception by the base station 1.
Fig. 3 depicts a method for completing X2removal in the case of establishing an X2 connection between base stations through an X2 gateway, comprising:
step 301, the base station 1 and the base station 2 are connected through an X2 gateway, and if the base station 1 detects that the X2 connection between the base station 1 and the base station 2 needs to be removed, an X2removal request message is sent to an X2 gateway connected to the base station, specifically, the X2removal request message is encapsulated in an X2 interface information transmission message and sent. The X2 interface information transfer message contains base station identification information of the source and target base stations, i.e., eNBID of base station 1 and base station 2. Optionally, the message further includes X2REMOVAL indication information, where the X2REMOVAL indication information is used to indicate that the X2 interface information transmission message includes an X2 remove procedure (or X2 remove request) message.
Step 302, after receiving the X2 interface information transmission message, the X2 gateway routes the message to the base station 2 according to the target base station identification information in the message.
In step 303, the base station 2 accepts to remove the X2 connection with the base station 1, and replies an X2removal response message to the X2 gateway. Similarly, the X2 remove response message envelope is sent in an X2AP messaging (X2apmessage range) message. The X2 interface information transfer message contains base station identification information of the source and target base stations, i.e., the eNBID of base station 2 and base station 1. In addition, the message also contains X2 remove indication information, and the X2 remove indication information is used for indicating that the X2 interface information transmission message contains an X2 remove procedure (or X2 remove response) message. Base station 2 may then delete information related to the X2 connection of base station 1, such as resources, application layer configuration data, and the like. After receiving the X2 interface information transmission message, the X2 gateway resolves that the message contains the X2 remove indication information, and then executes the corresponding X2REMOVAL operation, i.e. deletes the X2 connection relationship information of the base station 1 and the base station 2. Or, after the X2 gateway resolves that the received X2 interface information transmission message includes the X2 remove motion indication information, it resolves the encapsulated X2AP message in the message, and if the encapsulated X2AP message is the X2 remove motion response message, it executes the corresponding X2REMOVAL operation, i.e. deletes the X2 connection relationship information of the base station 1 and the base station 2.
At step 304, the X2 gateway routes the X2 interface information transfer message encapsulating the X2 remove response message to the base station 1. The information related to the X2 connection of the base station 2, such as resources, application layer configuration data, etc., may be deleted after the reception by the base station 1.
Further, the base station includes: a macro base station, and/or a home base station.
Fig. 4 shows an error indication method in the case of establishing an X2 connection between base stations through an X2 gateway, including:
in step 401, the base station 1 needs to initiate an X2 establishment procedure with the base station 2, and since it needs to establish a proxy X2 connection through an X2 gateway, the base station 1 first sends an X2 interface information transmission message to the X2 gateway. The X2 interface information transfer message contains the eNBID of the source and target base stations, as well as the corresponding X2 setup message. The target base station for this message is base station 2.
In step 402, the base station 1 wants to initiate an X2removal procedure to the base station 3, and since the X2 connection is established between the base station 1 and the base station 3 through the X2 gateway, the base station 1 sends the X2 interface information transmission message to the X2 gateway. The X2 interface information transfer message contains the eNBID of the source and target base stations, which is base station 3, and the corresponding X2 remove message.
In step 403, the X2 gateway routes the X2 interface information transfer message containing the X2 remove message to the base station 3 according to the maintained entid and IP address information of the connected base station.
In step 404, since the mapping information of the enb id and the IP address of the base station 2 is maintained in the X2 gateway, it cannot route the X2 interface information transmission message that the target base station received from the base station 1 is the base station 2.
In step 405, if the X2 gateway cannot route the X2 interface information transmission message, an error indication message is sent to the base station 1. The error indication message at least contains the target base station identification information (i.e., eNBID of base station 2) in the X2 interface information transmission message that it cannot route. Optionally, the error indication message may further include enb id information of the base station 1. After receiving the error indication information, the base station 1 can determine that the X2 establishment request message sent to the base station 2 fails to be routed at the X2 gateway. Optionally, base station 1 may subsequently initiate a TNL address discovery procedure to base station 2 to continue to complete its X2 connection establishment procedure with base station 2.
It can be seen that, by adopting the above scheme, the X2 gateway controls the X2 connection removal between base stations according to the X2removal procedure message sent by the base station; therefore, the X2 gateway can timely know the removal condition of the X2 connection between the base stations, the X2 gateway can normally maintain the X2 connection information between the connected base stations, and unnecessary X2 messages are effectively reduced.
Example II,
An embodiment of the present invention provides a method for processing an X2 interface message, which is applied to a base station, and as shown in fig. 5, the method includes:
step 501: generating an X2 remove procedure message;
step 502: sending an X2removal procedure message to an X2 gateway, so that the X2 gateway removes the connection information of the X2 interface of the corresponding base station according to the X2removal procedure message.
Here, the X2removal procedure message includes at least one of: x2 remove request message, X2 remove response message, X2 remove failure message.
It is understood that, corresponding to the first embodiment, the sending of the X2removal procedure message to the X2 gateway also has two cases:
case one, including the X2removal process message in an X2 interface information transfer message and sending; the X2removal indication information is used for indicating a message type contained in the X2 interface information transmission message or indicating information for controlling an X2 gateway to perform an X2removal operation; the message types include the following: x2 remove request message, X2 remove response message, X2 remove failure message.
In case two, the sending of the X2removal procedure message to the X2 gateway includes: not included in the X2 interface information transfer message, but the X2removal procedure message is directly sent.
Wherein, the X2removal process message carries identification information of the target base station and/or the source base station.
As shown in fig. 2, the base station (eNB)1 and the base station (eNB)2 may be a home base station or a macro base station, and the method of X2removal is completed when an X2 connection is established between the base stations through an X2 gateway. The method specifically comprises the following steps:
step 201, the base station 1 and the base station 2 establish an X2 connection through an X2 gateway, and if the base station 1 detects that the X2 connection between the base station 1 and the base station 2 needs to be removed, an X2removal request message is sent to a connected X2 gateway, and the X2removal request message is not encapsulated in an X2AP message transfer message, but is directly sent to an X2 gateway.
Wherein, the X2 removes the base station identification information of the source and target base stations, i.e. the eNBID of base station 1 and base station 2, contained in the request message.
In step 202, the X2 gateway routes the X2 remove request message to the base station 2 according to the target base station id in the X2 remove request message sent from the base station 1.
In step 203, when the base station 2 determines to remove the X2 connection with the base station 1 according to the received X2removal request message, it replies an X2removal response message to the X2 gateway.
Wherein the X2removal response message is also not encapsulated in the X2AP messaging message, but is sent directly to the X2 gateway. The X2 removes the base station identification information of the source base station and the target base station contained in the response message.
And, the base station 2 may delete the X2 connection related information with the base station 1, and the X2 connection related information may include: resources, application layer configuration data.
In step 204, after receiving the X2removal response message, corresponding X2removal operation may be performed, that is, the X2 connection relationship information of the base station 1 and the base station 2 is deleted.
If the subsequent X2 gateway detects that the SCTP connection between the gateway and the base station 1 (or the base station 2) is disconnected, it will send an X2 release message to the base station with the X2 connection between the base station 1 (or the base station 2). Since the X2 gateway has deleted the X2 connection relationship information for base station 1 and base station 2, the X2 gateway does not send an X2 release message to base station 2 (or base station 1).
In step 205, the X2 gateway routes the X2 remove response message to base station 1 according to the target base station identity in the received X2 remove response message.
The information related to the X2 connection of the base station 2, such as resources, application layer configuration data, etc., may be deleted after the reception by the base station 1.
Fig. 3 depicts a method for completing X2removal in the case of establishing an X2 connection between base stations through an X2 gateway, comprising:
step 301, the base station 1 and the base station 2 are connected through an X2 gateway, and if the base station 1 detects that the X2 connection between the base station 1 and the base station 2 needs to be removed, an X2removal request message is sent to an X2 gateway connected to the base station, specifically, the X2removal request message is encapsulated in an X2 interface information transmission message and sent. The X2 interface information transfer message contains base station identification information of the source and target base stations, i.e., eNBID of base station 1 and base station 2. Optionally, the message further includes X2REMOVAL indication information, where the X2REMOVAL indication information is used to indicate that the X2 interface information transmission message includes an X2 remove procedure (or X2 remove request) message.
Step 302, after receiving the X2 interface information transmission message, the X2 gateway routes the message to the base station 2 according to the target base station identification information in the message.
In step 303, the base station 2 accepts to remove the X2 connection with the base station 1, and replies an X2removal response message to the X2 gateway. Similarly, the X2 remove response message envelope is sent in an X2AP messaging (X2apmessage range) message. The X2 interface information transfer message contains base station identification information of the source and target base stations, i.e., the eNBID of base station 2 and base station 1. In addition, the message also contains X2 remove indication information, and the X2 remove indication information is used for indicating that the X2 interface information transmission message contains an X2 remove procedure (or X2 remove response) message. Base station 2 may then delete information related to the X2 connection of base station 1, such as resources, application layer configuration data, and the like. After receiving the X2 interface information transmission message, the X2 gateway resolves that the message contains the X2 remove indication information, and then executes the corresponding X2REMOVAL operation, i.e. deletes the X2 connection relationship information of the base station 1 and the base station 2. Or, after the X2 gateway resolves that the received X2 interface information transmission message includes the X2 remove motion indication information, it resolves the encapsulated X2AP message in the message, and if the encapsulated X2AP message is the X2 remove motion response message, it executes the corresponding X2REMOVAL operation, i.e. deletes the X2 connection relationship information of the base station 1 and the base station 2.
At step 304, the X2 gateway routes the X2 interface information transfer message encapsulating the X2 remove response message to the base station 1. The information related to the X2 connection of the base station 2, such as resources, application layer configuration data, etc., may be deleted after the reception by the base station 1.
It can be seen that, by adopting the above scheme, the X2 gateway controls the X2 connection removal between base stations according to the X2removal procedure message sent by the base station; therefore, the X2 gateway can timely know the removal condition of the X2 connection between the base stations, the X2 gateway can normally maintain the X2 connection information between the connected base stations, and unnecessary X2 messages are effectively reduced.

Fig. 9 shows one of the scenarios applied in the embodiment of the present invention, wherein, as can be seen from the figure, the access network is composed of a plurality of evolved base stations (enbs), a plurality of home base stations (henbs), an X2 gateway, and a HeNB gateway; the eNB is connected to a Mobility Management Entity (MME) or a serving gateway (S-GW) through an S1 interface, that is, messages are transferred between the eNB or the HeNB through an X2 interface, and messages are transferred between the eNB or the HeNB and the HeNB gateway through an S1 interface. The base station includes: a macro base station, and/or a home base station.
The following describes the method provided in the present embodiment by way of a scenario.
As shown in fig. 2, the base station (eNB)1 and the base station (eNB)2 may be a home base station or a macro base station, and the method of X2removal is completed when an X2 connection is established between the base stations through an X2 gateway. The method specifically comprises the following steps:
step 201, the base station 1 and the base station 2 establish an X2 connection through an X2 gateway, and if the base station 1 detects that the X2 connection between the base station 1 and the base station 2 needs to be removed, an X2removal request message is sent to a connected X2 gateway, and the X2removal request message is not encapsulated in an X2AP message transfer message, but is directly sent to an X2 gateway.
Wherein, the X2 removes the base station identification information of the source and target base stations, i.e. the eNBID of base station 1 and base station 2, contained in the request message.
In step 202, the X2 gateway routes the X2 remove request message to the base station 2 according to the target base station id in the X2 remove request message sent from the base station 1.
In step 203, when the base station 2 determines to remove the X2 connection with the base station 1 according to the received X2removal request message, it replies an X2removal response message to the X2 gateway.
Wherein the X2removal response message is also not encapsulated in the X2AP messaging message, but is sent directly to the X2 gateway. The X2 removes the base station identification information of the source base station and the target base station contained in the response message.
And, the base station 2 may delete the X2 connection related information with the base station 1, and the X2 connection related information may include: resources, application layer configuration data.
In step 204, after receiving the X2removal response message, corresponding X2removal operation may be performed, that is, the X2 connection relationship information of the base station 1 and the base station 2 is deleted.
If the subsequent X2 gateway detects that the SCTP connection between the gateway and the base station 1 (or the base station 2) is disconnected, it will send an X2 release message to the base station with the X2 connection between the base station 1 (or the base station 2). Since the X2 gateway has deleted the X2 connection relationship information for base station 1 and base station 2, the X2 gateway does not send an X2 release message to base station 2 (or base station 1).
In step 205, the X2 gateway routes the X2 remove response message to base station 1 according to the target base station identity in the received X2 remove response message.
The information related to the X2 connection of the base station 2, such as resources, application layer configuration data, etc., may be deleted after the reception by the base station 1.
Fig. 3 depicts a method for completing X2removal in the case of establishing an X2 connection between base stations through an X2 gateway, comprising:
step 301, the base station 1 and the base station 2 are connected through an X2 gateway, and if the base station 1 detects that the X2 connection between the base station 1 and the base station 2 needs to be removed, an X2removal request message is sent to an X2 gateway connected to the base station, specifically, the X2removal request message is encapsulated in an X2 interface information transmission message and sent. The X2 interface information transfer message contains base station identification information of the source and target base stations, i.e., eNBID of base station 1 and base station 2. Optionally, the message further includes X2REMOVAL indication information, where the X2REMOVAL indication information is used to indicate that the X2 interface information transmission message includes an X2 remove procedure (or X2 remove request) message.
Step 302, after receiving the X2 interface information transmission message, the X2 gateway routes the message to the base station 2 according to the target base station identification information in the message.
In step 303, the base station 2 accepts to remove the X2 connection with the base station 1, and replies an X2removal response message to the X2 gateway. Similarly, the X2 remove response message envelope is sent in an X2AP messaging (X2apmessage range) message. The X2 interface information transfer message contains base station identification information of the source and target base stations, i.e., the eNBID of base station 2 and base station 1. In addition, the message also contains X2 remove indication information, and the X2 remove indication information is used for indicating that the X2 interface information transmission message contains an X2 remove procedure (or X2 remove response) message. Base station 2 may then delete information related to the X2 connection of base station 1, such as resources, application layer configuration data, and the like. After receiving the X2 interface information transmission message, the X2 gateway resolves that the message contains the X2 remove indication information, and then executes the corresponding X2REMOVAL operation, i.e. deletes the X2 connection relationship information of the base station 1 and the base station 2. Or, after the X2 gateway resolves that the received X2 interface information transmission message includes the X2 remove motion indication information, it resolves the encapsulated X2AP message in the message, and if the encapsulated X2AP message is the X2 remove motion response message, it executes the corresponding X2REMOVAL operation, i.e. deletes the X2 connection relationship information of the base station 1 and the base station 2.
At step 304, the X2 gateway routes the X2 interface information transfer message encapsulating the X2 remove response message to the base station 1. The information related to the X2 connection of the base station 2, such as resources, application layer configuration data, etc., may be deleted after the reception by the base station 1.
Further, the base station includes: a macro base station, and/or a home base station.
Fig. 4 shows an error indication method in the case of establishing an X2 connection between base stations through an X2 gateway, including:
in step 401, the base station 1 needs to initiate an X2 establishment procedure with the base station 2, and since it needs to establish a proxy X2 connection through an X2 gateway, the base station 1 first sends an X2 interface information transmission message to the X2 gateway. The X2 interface information transfer message contains the eNBID of the source and target base stations, as well as the corresponding X2 setup message. The target base station for this message is base station 2.
In step 402, the base station 1 wants to initiate an X2removal procedure to the base station 3, and since the X2 connection is established between the base station 1 and the base station 3 through the X2 gateway, the base station 1 sends the X2 interface information transmission message to the X2 gateway. The X2 interface information transfer message contains the eNBID of the source and target base stations, which is base station 3, and the corresponding X2 remove message.
In step 403, the X2 gateway routes the X2 interface information transfer message containing the X2 remove message to the base station 3 according to the maintained entid and IP address information of the connected base station.
In step 404, since the mapping information of the enb id and the IP address of the base station 2 is maintained in the X2 gateway, it cannot route the X2 interface information transmission message that the target base station received from the base station 1 is the base station 2.
In step 405, if the X2 gateway cannot route the X2 interface information transmission message, an error indication message is sent to the base station 1. The error indication message at least contains the target base station identification information (i.e., eNBID of base station 2) in the X2 interface information transmission message that it cannot route. Optionally, the error indication message may further include enb id information of the base station 1. After receiving the error indication information, the base station 1 can determine that the X2 establishment request message sent to the base station 2 fails to be routed at the X2 gateway. Optionally, base station 1 may subsequently initiate a TNL address discovery procedure to base station 2 to continue to complete its X2 connection establishment procedure with base station 2.
It can be seen that, by adopting the above scheme, the X2 gateway controls the X2 connection removal between base stations according to the X2removal procedure message sent by the base station; therefore, the X2 gateway can timely know the removal condition of the X2 connection between the base stations, the X2 gateway can normally maintain the X2 connection information between the connected base stations, and unnecessary X2 messages are effectively reduced.
And the base station can correctly identify the X2 process corresponding to the received error indication message, so that the base station correctly executes the X2 interface function.
