Detailed Description
The embodiment of the invention provides a processing method and device for recovering network connection and network side equipment.
In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, shall fall within the scope of the invention.
As shown in fig. 1, an embodiment of the present invention provides a processing method for recovering network connection, where an execution body of the method may be a mobility management entity MME, and the method may quickly improve efficiency of successful called connection of a user equipment under a failed link and robustness of a communication network when a link failure corresponding to a predetermined interface between target base stations is detected. The method specifically comprises the following steps:
in S101, when a link failure corresponding to a predetermined interface between the target base stations is detected, a time interval for the user equipment to switch between the connected state and the idle state is determined according to the connection state of the user equipment reported by the target base stations.
In implementation, with the development of large-scale spreading construction of LTE networks and related communication technologies, in public network LTE, in order to support networking between multiple core networks and disaster recovery when a core network fails, a concept of a mobility management entity resource Pool (Mobility Management Entity Pool, MME Pool) is proposed, and in general, all network elements under the MME Pool start a VOLTE disaster recovery function. The user terminal (UE) completes normal attachment through a mobility management entity (Mobility Management Entity, MME) in the MME Pool, creates IMS PDN default bearer, and the user MM/SM context is backed up on another backup mobility management entity (Redundant Mobility Management Entity, R-MME) in the same MME Pool or on other backup servers through a mobility management entity (MobilityManagement Entity, MME) disaster recovery function. Under normal conditions, the UE completes attachment on the MME and can perform the VOLTE voice service of the caller or the callee normally. However, if a link between a base station (eNodeB) and a certain MME in an MME Pool fails, for a called ue under the failed link, when the ue is in an idle state, the ue maintains its idle state, and when the ue is in a connected state, the MME corresponding to the ue sends a release access bearer request (Release Access Bearer Request) to a Serving gateway (S-GW), so as to notify the S-GW to delete the s1_u bearer resource of the ue, that is, to switch the state of the ue in the connected state to the idle state. At this time, if the ue under the failed link has the called service, after the paging message arrives at the S-GW, the S-GW may send a downlink data notification message to the MME where the ue is located, and then the MME sends the paging message to the ue, but due to the link failure between the MME and the eNodeB attached to the ue, the ue cannot receive the paging message, which results in failure of the user called. Therefore, the embodiment of the invention provides a technical scheme capable of solving the problems, and the specific details can be seen in the following.
Specifically, the mobility management entity MME may add a variable identifier (such as a boolean type variable s1link_status) to each registered user, and record the state of the variable identifier to mark the ue under the failed LINK. For example, when the ue is in a connected state, if it is detected that the link between the MME and the eNodeB to which the ue is attached is normal, the mobility management entity MME may set the variable identifier to 0, and if the link between the MME and the eNodeB to which the ue is attached fails, the mobility management entity MME may set the variable identifier to 1. When the ue is in idle state, if the MME detects that the link between the MME and the eNodeB attached to the ue last time the ue accessed the target base station is normal, the MME may set the variable identifier to 0, and if the MME detects that the link between the MME and the eNodeB attached to the ue last time the ue accessed the target base station is failed, the MME may set the variable identifier to 1.
Under the condition that the mobile management entity MME detects the link failure corresponding to the preset interface between the target base stations, the time interval for switching the user equipment between the connected state and the idle state can be determined according to the connection state of the user equipment reported by the target base stations and the marking information of the user equipment under the failed link detected by the mobile management entity MME.
In S102, if the time interval is smaller than the predetermined threshold, a release access bearer request is sent to the service gateway, where the release access bearer request includes target mark information and related information of the ue, and the target mark information is used to trigger the service gateway to execute the network connection processing for recovering the ue when receiving the paging message for the ue.
In implementation, when the mobility management entity MME detects that the time interval of the transition between the connected state and the idle state of the ue is smaller than a predetermined threshold, the mobility management entity MME may first acquire the target flag information, may then generate a release access bearer request, may add the target flag information to the release access bearer request, and may send the release access bearer request to which the target flag information has been added to the serving gateway after the addition is completed, so when the serving gateway receives the release access bearer request to which the target flag information has been added sent by the mobility management entity MME, the serving gateway may delete s1_u bearer resources of the ue, and may identify the ue, so as to obtain identification information of the ue. When the user equipment on the fault link has the called service, the service gateway can send a downlink data notification message DDN to other MMEs in the MME Pool according to the identification information, and the other MMEs send paging messages to trigger the user equipment to resume the connection with the network.
Specifically, a timer may be added in the mobility management entity MME, and a preset threshold T-IDLE may be set for the timer, where the timer may be used to record a time interval of transition between a connection state and an IDLE state of each user equipment, and when the timer detects that the time interval of transition between the connection state and the IDLE state of the user equipment is smaller than the preset threshold T-IDLE state, the mobility management entity MME may first obtain target mark information, then may generate a release access bearer request, may add the obtained target mark information to the release access bearer request, and after the adding is completed, may send the release access bearer request with the added target mark information to the serving gateway, so when the serving gateway receives the release access bearer request with the added target mark information sent by the mobility management entity MME, delete s1_u bearer resources of the user, and simultaneously, may identify the user information, to obtain identification information of the user information. When the user equipment on the fault link has the called service, the IMS signaling or the data packet of the user equipment reaches a Serving gateway (S-GW), and after the Serving gateway detects the identification information of the user information, the Serving gateway may send a downlink data notification message DDN to other MMEs in the MME Pool in a round robin manner. If the MME which receives the DDN message sent by the service gateway S-GW does not have the backup information of the user, the MME obtains the backup information of the user on a backup server of the user information or other MME (such as R-MME), then sends a paging message to the user equipment according to the backup information, and after the user equipment receives the paging message, the MME can be reattached or a service request can be initiated to restore IMS PDN connection, and finally, the user equipment can receive the paging message.
According to the processing method for recovering network connection, under the condition that a link fault corresponding to a preset interface between target base stations is detected, the time interval for switching the user equipment between a connection state and an idle state is determined according to the connection state of the user equipment reported by the target base stations; and if the time interval is smaller than the preset threshold value, sending a release access bearer request to the service gateway, wherein the release access bearer request comprises target mark information and related information of the user equipment, and the target mark information is used for triggering the service gateway to execute network connection processing of recovering the user equipment when receiving the paging message of the user equipment. In this way, under the condition that the link fault corresponding to the preset interface between the target base stations is detected, the service gateway sends the release access bearing request carrying the target mark to the service gateway, so that when the service gateway receives the paging message of the user equipment, the method for recovering the network connection processing of the user equipment is executed, and the efficiency of successful called connection of the user equipment under the fault link and the robustness of the communication network are improved.
Further, the predetermined interface may be an S1 interface in the LTE communication network, and the target flag information may be flag information set based on a predetermined bit in the Indication of the 3 GPP.
The target mark information may be an Indication mark defined in 3gpp 29.274. Table 1 is an Indication label defined in 3gpp 29.274. As shown in table 1, bit 6 of the Octets 12 is spark, and thus, the bit may be a predetermined bit, and tag information such as S1CLD Indication (S1-C link down) may be set in the predetermined bit.
TABLE 1
In implementation, the above-mentioned target flag information, such as S1CLD Indication (S1-C link down), may be added to the release access bearer request of the S11 interface, where the above-mentioned added target flag information may be S1CLD Indication flag information that has been set to 1.
According to the processing method for recovering network connection, under the condition that a link fault corresponding to a preset interface between target base stations is detected, the time interval for switching the user equipment between a connection state and an idle state is determined according to the connection state of the user equipment reported by the target base stations; and if the time interval is smaller than the preset threshold value, sending a release access bearer request to the service gateway, wherein the release access bearer request comprises target mark information and related information of the user equipment, and the target mark information is used for triggering the service gateway to execute network connection processing of recovering the user equipment when receiving the paging message of the user equipment. In this way, under the condition that the link fault corresponding to the preset interface between the target base stations is detected, the service gateway sends the release access bearing request carrying the target mark to the service gateway, so that when the service gateway receives the paging message of the user equipment, the method for recovering the network connection processing of the user equipment is executed, and the efficiency of successful called connection of the user equipment under the fault link and the robustness of the communication network are improved.
As shown in fig. 2, the embodiment of the present disclosure provides a processing method for recovering network connection, where an execution body of the method may be a service gateway, and the method may quickly improve efficiency of successful called connection of a user equipment under a failed link and robustness of a communication network when a link failure corresponding to a predetermined interface between target base stations is detected. The method specifically comprises the following steps:
in S201, a release access bearer request sent by a mobility management entity MME is received, where the release access bearer request is sent when the MME detects that a link failure corresponding to a predetermined interface between target base stations connected to the MME and determines that a time interval of a transition between a connected state and an idle state of user equipment reported by the target base stations is smaller than a predetermined threshold, and the release access bearer request includes target flag information and related information of the user equipment, where the target flag information is used to trigger a serving gateway to execute network connection processing for recovering the user equipment when receiving a paging message for the user equipment.
In S202, according to the related information of the ue, the related resources of the ue that is loaded are released.
In implementation, after receiving a release access bearer request sent by a mobility management entity MME, a service gateway may release s1_u bearer resources of a user according to related information of the user equipment carried in the request, and meanwhile, the service gateway may detect whether the received release access bearer request carries target mark information, and if it is detected that the received release access bearer request carries the target mark information, the service gateway may identify the user information, so as to obtain identification information of the user information. When the user equipment on the fault link has the called service, the service gateway can send a downlink data notification message DDN to other MMEs in the MME Pool according to the identification information, and the other MMEs send paging messages to trigger the user equipment to resume the connection with the network.
The method for processing network connection recovery in the embodiment of the invention comprises the steps of receiving a release access bearer request sent by a Mobile Management Entity (MME), wherein the release access bearer request is sent when the MME detects a link fault corresponding to a preset interface between target base stations connected with the MME and determines that a time interval of switching between a connection state and an idle state of user equipment reported by the target base stations is smaller than a preset threshold value, the release access bearer request comprises target mark information and related information of the user equipment, and the target mark information is used for triggering a service gateway to execute network connection processing of recovering the user equipment when a paging message of the user equipment is received; and then, according to the related information of the user equipment, releasing the related resources of the user equipment. In this way, when the service gateway receives the release access bearer request sent by the mobility management entity MME, it detects that the release access bearer request includes the target mark information, and then, when receiving the paging message for the user equipment, executes the method for recovering the network connection processing of the user equipment, thereby improving the efficiency of successful called connection of the user equipment under the faulty link and the robustness of the communication network.
Further, the service gateway may further perform the following processing of S203 to S204 when receiving that the user has the called service on the failed link.
In S203, a paging message for the user equipment is received, where the paging message includes information about the user equipment.
The paging message may be a Downlink Data message (DD) sent to the service gateway when the Data packet gateway determines that there is a voice call service to the ue, where the paging message carries relevant information of the ue, and the relevant information may be an international mobile subscriber identity (International Mobile Subscriber Identification Number, IMSI) of the ue, or other relevant information of the ue, which is not specifically limited herein.
In S204, based on the target flag information, sending paging messages to other MMEs in the same management entity device pool as the MME, so that the other MMEs send the paging messages to the user equipment through the target base station to restore the network connection of the user equipment.
In an implementation, the service gateway may first detect whether the release access bearer request carries target flag information or not, or detect whether the target flag information carried in the release access bearer request is set, based on a release access bearer request received from the mobility management entity MME, so that, when detecting that the release access bearer request carries the target flag information, or detect that the target flag information carried in the release access bearer request is set, the service gateway may send the downlink data notification message DDN to other MMEs in the MME Pool in a round-robin manner. If the MME which receives the DDN message sent by the service gateway S-GW does not have the backup information of the user equipment, the MME obtains the backup information of the user on a backup server of the user information or other MME (such as R-MME), then sends a paging message to the user equipment according to the backup information, and after the user receives the paging message, the MME can be reattached or a service request can be initiated to restore IMS PDN connection, and finally the user equipment can receive the paging message.
The method for processing network connection recovery in the embodiment of the invention comprises the steps of receiving a release access bearer request sent by a Mobile Management Entity (MME), wherein the release access bearer request is sent when the MME detects a link fault corresponding to a preset interface between target base stations connected with the MME and determines that a time interval of switching between a connection state and an idle state of user equipment reported by the target base stations is smaller than a preset threshold value, the release access bearer request comprises target mark information and related information of the user equipment, and the target mark information is used for triggering a service gateway to execute network connection processing of recovering the user equipment when a paging message of the user equipment is received; and then, according to the related information of the user equipment, releasing the related resources of the user equipment. In this way, when the service gateway receives the release access bearer request sent by the mobility management entity MME, it detects that the release access bearer request includes the target mark information, and then, when receiving the paging message for the user equipment, executes the method for recovering the network connection processing of the user equipment, thereby improving the efficiency of successful called connection of the user equipment under the faulty link and the robustness of the communication network.
