Illustratively, the radio network access device 12 is a base station, the terminal device 11 is a mobile terminal used by a user, and the failure weakening means that in an LTE BtrunC network, when communication between the base station and a core network is interrupted or the core network fails, the base station should be able to process a registration request of the user within the range of the base station, and support services such as single call and group call.
The existing failure weakening judgment method is that a base station needs to be disconnected with all core networks, the base station enters a failure weakening processing mode at this time, and basic service under failure weakening can be performed between UEs under the base station.
In order to solve the above problem, embodiments of the present application provide a method, a device, and a communication system for processing failure weakening, where when a base station is connected to multiple core networks, if one of the core networks fails, the base station broadcasts a first system message or a second system message to all terminal devices, and notifies the terminal devices in the failed core network to enter a failure weakening processing mode, so that the base station can enter a partial failure weakening processing mode, and while ensuring that terminal devices in other normal core networks can perform normal services, the terminal devices in the failed core network can also perform failure weakening processing, thereby implementing basic services.
The technical solution of the present application will be described in detail below with reference to specific examples. It should be noted that the following several specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a schematic flowchart of a first embodiment of a processing method for failure weakening provided in the embodiment of the present application, where the processing method may be applied to a wireless network access device, and takes a base station as an example, where the base station is connected to at least two core networks, and an execution subject of the method may be the base station, and specifically may include the following steps:
s201, obtaining the operator network information of at least two core networks.
In the embodiment of the present application, the core network includes an enhanced Service module (ASU) and an MME, and exemplarily, the operator network includes china mobile, china telecommunications, and china alliance, and for convenience of description, the first core network is referred to as a PLMN1, and the second core network is referred to as a PLMN2, where PLMN1 and PLMN2 may belong to the same operator network or may belong to different operator networks, the first core network includes an MME PLMN1, the second core network includes an MME PLMN2, and the base station establishes a connection with MME PLMN1 and MME PLMN2 through the ASU.
For example, the base station establishes an S1 connection with the MME PLMN1 and the MME PLMN2, and negotiates supported application layer parameters such as PLMNs through S1AP-S1 setup request (supported TAs)/response (supported policies > supported PLMNs) messages.
For example, in some embodiments, the base station may be connected to multiple core networks through Radio access sharing (RAN sharing), and the number of the core networks may be two or more.
S202, when the operator networks to which at least two core networks belong are the same and a first core network fault is detected, broadcasting a first system message to terminal equipment belonging to each core network.
The first System message includes a user number segment for instructing a corresponding terminal device to perform a fault-weakening process, and exemplarily, the first System message includes a SIB32 Type System Information Block Type reporting defined, where the Type carries an IMSISegList identifier for instructing the fault-weakening user number segment.
Illustratively, the user number segment represents identity information of a terminal device of the user, and can be a multi-bit digital code, wherein the number of bits of the digital code can be determined according to the number of the total users.
After receiving the user number segment, the terminal device performs fault weakening processing if the user number segment is the same as the user number segment contained in the first system message, and continues normal service if the user number segment is different from the user number segment contained in the first system message.
Illustratively, the fail-soft process may be that the terminal device re-registers with the failed ASU MME.
In this embodiment, the first core network may refer to any one or more of core networks connected to the base station, where the plurality of core networks does not include all core networks connected to the base station.
For example, a terminal device belonging to the MME PLMN1 may be referred to as UE PLMN1, a terminal device belonging to the MME PLMN2 may be referred to as UE PLMN2, and the first core network may be PLMN1, and when the PLMN1 fails and the base station is disconnected from the PLMN1, the base station broadcasts a first system message to the UE PLMN1 and the UE PLMN 2.
S203, when the operator networks of at least two core networks are different and the first core network is detected to be in failure, broadcasting a second system message to the terminal equipment belonging to each core network.
The second system message includes an operator network identifier used for instructing the corresponding terminal device to perform the graceful degradation process, and exemplarily, the second system message includes a SIB32 type systemlnformationblocktypereporting, where the type carries a PLMNList identifier and is used for instructing a graceful PLMN list, where the PLMN list includes PLMN1, PLMN2, and the like.
For example, if the PLMN list includes the PLMN1, that is, the base station is disconnected from the core network PLMN1, when the core network selected by the UE to be accessed is the PLMN1, the UE may perform the failure weakening process.
Illustratively, the fail-over includes the UE re-registering with the failed ASU MME.
According to the method and the device, whether the core networks belong to the same operator network is determined, different system messages are broadcast to the terminal equipment, and the corresponding terminal equipment is informed to perform fault weakening processing, so that when the base station is disconnected with part of the core networks, part of the terminal equipment can enter a fault processing mode, the terminal equipment under the core networks which belong to the broken links is enabled to perform the fault processing mode, and basic services can be guaranteed.
Illustratively, on the basis of the foregoing embodiments, in some embodiments, the step S201 further includes, before the step S, the step of: and broadcasting the third system message and the paging message to the terminal equipment residing in the coverage area of the wireless access network, and accessing the terminal equipment to the core network.
The third system message includes operator network information to which each core network belongs, and the paging message is used for paging each terminal device.
Specifically, the third System message may include System Information Block type1, which contains PLMN-identylist, that is, operator network Information to which the core network belongs, and the terminal device under the coverage of the base station performs PLMN selection and cell selection according to the third System message, determines to access the corresponding core network, and meanwhile, the terminal device resides in a cell to receive System Information and paging Information of the base station.
Further, on the basis of the above embodiment, the base station may broadcast the third system message and the paging message to each terminal device; and receiving the confirmation mark reported by each terminal device, and accessing the core network corresponding to the confirmation mark for each terminal device.
Wherein, the confirmation identification comprises the operator network identification and/or the mobile management node registration information of the core network.
Illustratively, the operator network Identity may be selected plmn-Identity and the mobility management node registration information of the core network may be registered MME. After receiving the third system message and the paging message, the terminal device performs PLMN selection and cell selection, for example, selecting PLMN1 or PLMN2, and after the selection is completed, the terminal device initiates an RRC Connection establishment procedure to the base station, and the RRC Connection Setup Complete message carries a selected PLMN-Identity and/or registered MME, specifically including a PLMN identifier selected by the terminal device and a registration MME, and the base station selects, according to the PLMN identifier reported by the terminal device, an MME that needs to establish a Connection for the terminal device.
In some embodiments, when the operator information of at least two core networks is different and a failure of a first core network is detected, a second core network may be detected, and if the first core network and the second core network fail simultaneously (that is, all core networks connected to the base station fail simultaneously), a first system message is broadcast to a terminal device belonging to each core network, and a service request between terminal devices belonging to different core networks is intercepted.
Specifically, as the terminal equipment performing the fault weakening process needs to register in the ASU MME, the ASU MME can acquire user subscription information, intercept the point call service of the UE between different core networks through the ASU MME, and isolate the UE between different core networks, thereby satisfying the user security isolation.
Fig. 3 is a schematic flowchart of a second embodiment of the fault weakening method provided in the embodiment of the present application, where the method may be applied to a terminal device, and an execution main body of the method takes the terminal device as an example, and specifically includes the following steps:
s301, acquiring a first system message or a second system message broadcasted by the wireless access network equipment.
Specifically, when the base station is disconnected from the first core network, the first system information or the second system information may be broadcasted to the terminal device, and explanations of the first system information and the second system information are described above and are not described herein again.
S302, reading the first system message, determining to perform fault weakening treatment according to the current user number segment of the terminal equipment, or reading the second system message, and determining to perform fault weakening treatment according to the current operator network information of the terminal equipment.
The current user number segment is the identifier of the terminal device, and the current operator network information is the operator network to which the core network accessed by the terminal device currently belongs.
Specifically, when the terminal device receives the first system message, if the number segment of the user in the first system is the same as the current number segment of the user of the terminal device, the characterization base station indicates the terminal device to perform the fault weakening processing, and when the terminal device receives the second system message, if the operator network identifier in the second system message is the same as the current operator network information of the terminal device, the characterization base station indicates the terminal device to perform the fault weakening processing.
When the terminal equipment fails, a registration request can be sent to the wireless network access equipment.
Wherein the registration request is used for the terminal device to re-register to the wireless network access device.
For example, the failure weakening process may be that the terminal device re-registers under the failed ASU MME.
According to the method and the device, the first system information or the second system information is read, and whether fault weakening processing needs to be carried out or not is determined according to the current user number segment and the current operator network information, so that the base station can partially carry out a fault weakening processing mode, and basic services can still be carried out on the terminal equipment under the condition that the accessed core network has a fault.
Illustratively, in some embodiments, the terminal device compares the user number segment with the current user number segment by obtaining the user number segment of the first system message, performs the fault weakening processing if the user number segment is the same as the current user number segment, and does not perform the fault weakening processing if the user number segment is not the same as the current user number segment.
Specifically, the user number segment may refer to identity information of a terminal device accessing a core network disconnected from the base station.
For example, in some embodiments, the terminal device obtains the operator network identifier of the second system message, compares the operator network identifier with current operator network information, performs the failure weakening processing if the operator network identifier is the same as the current operator network information, and does not perform the failure weakening processing if the operator network identifier is the same as the current operator network information.
Specifically, the operator network identifier is used to identify a core network that is disconnected from the base station, and the core network belongs to the operator network.
Fig. 4 is a flowchart illustrating a third embodiment of a failure weakening method provided in the embodiment of the present application, and as shown in fig. 4, in the embodiment of the present application, two core networks are taken as an example, including a large network MME PLMN1 and a large network MME PLMN2, and the operator network information of the two core networks is different, which includes the following steps:
s401, ENB establishes connection with a large-network MME PLMN1 through an ASU (MME) and establishes connection with a large-network MME PLMN 2.
Illustratively, the ENB establishes S1 connection with the large-network MME PLMN1 and MME PLMN2 through asu (MME).
S402, the ENB broadcasts PLMN-IdentityList in System Information System Information Block Type1 to a PLMN list supported by the terminal equipment, wherein the terminal equipment comprises a UE PLMN1 (used for accessing a large-network MME PLMN1) and a UE PLMN2 (used for accessing a large-network MME PLMN 2).
And S403, when the ENB is disconnected from the large-network MME PLMN1 and is normally connected with the large-network MME PLMN2, the ENB informs the UE PLMN1 to perform fault weakening treatment, and the UE PLMN2 continues to ensure normal operation.
Specifically, the ENB defines, in a System Information message of an air interface, an SIB32 type System Information block type reporting to indicate a Trunking terminal device, where the type carries a PLMNList identifier to indicate a failed PLMN list, and when a PLMN selected by the terminal device to be accessed is in the PLMN list, the terminal device needs to perform failure weakening processing.
Illustratively, if PLMN1 is included in the PLMN list, UE PLMN1 needs to be fail-soft.
Illustratively, the System Information message is defined as follows:
System Information BlockType Trunking::＝SEQUENCE{
tPCCH-Config TPCCH-Config,
cellFailurePLMNList PLMN-IdentityList OPTIONAL，Need OR
p-t ENUMERATED{dB-6，dB-4dot77，dB-3，dB-1dot77，dB0，dB1，dB2，dB3}OPTIONAL，--Need OP
trunkingBsrInd ENUMERATED{true}OPTIONAL，Need OR
nonCriticalExtension SystemInformationBlockTypeTrunking-R2-IEs OPTIONAL Need OP}
s404, after the UE PLMN1 receives the indication of the failure and the PLMN selected by the current UE PLMN1 is in the list of the failed PLMN, the UE PLMN1 re-registers with the failed ASU MME, for example, in the failure mode.
S405, the UE PLMN2 continues to perform service in the normal mode, and the UE PLMN1 and the UE PLMN2 do not perform service intercommunication.
Particularly, when the ENB is disconnected from all connected core networks, all UEs under the base station enter a failure-weakening mode for registration, the peer call service of the terminal device between different PLMNs is controlled by the ASU MME to be rejected, and the cluster grouping between different PLMNs is performed separately according to the PLMNs.
Fig. 5 is a flowchart illustrating a fourth embodiment of a method for processing failure weakening according to the present embodiment, as shown in fig. 5, in the embodiment of the present application, two core networks are taken as an example, including a macro network MME-a PLMN and a macro network MME-B PLMN, and the operator network information of the two core networks is the same, which includes the following steps:
s501, the ENB establishes connection with a large-network MME-A PLMN through an ASU (MME) and establishes connection with a large-network MME-B PLMN.
