Technical Field

The present application relates to the field of communications technologies, and in particular, to a bearer release method and apparatus, an electronic device, and a computer-readable storage medium.

Background

The S1 interface is an interface between an MME (mobility management entity)/S-GW (serving gateway) gateway and an eNB (evolved nodeb). When the core network and the access network release the E-RAB (evolved radio Access bearer), the E-RAB release signaling flow of the S1-AP protocol is used. The 36413 protocol has a related description for the E-RABRELEEASEList cell of the E-RABRELEASERESPONSE message in the MME-initiated E-RAB Release procedure. Considering that when the base station is connected with the core network, the E-RAB release scenario initiated by the core network, the base station fails (such as processing error inside the base station) or the base station does not completely conform to the protocol, resulting in abnormal E-rabreleseList cells.

The S1-AP protocol of the S1 interface is described in detail in 3GPP (3rd generation partnership project) related protocols.

According to the description in the current 3GPP36413 protocol, for releasing the E-RAB that the user has established, the MME may initiate an E-rabresease procedure:

the MME shall include E-rabbetereleaselistie (information element) in the E-rabbetesecommand message, indicating which E-RABs the eNB releases.

After completing the release of the E-RAB, the eNB should notify the MME of the release result, including the successfully released E-RAB and the release failed E-RAB, using an E-rabrellesesoponsense (E-RAB release result) message.

36413 the E-RABRELEASEList cell for E-RABRELEASERESPONSE message is described as "Range 0.1", i.e. the base station needs to carry the E-RAB successfully released to the E-RABRELEASEList cell; if all E-RABs are failed to be released, the E-RABReleaseList cell does not exist, and the E-RABFailendReleaseList cell appears and carries the E-RABs with failed release.

When an abnormal scenario occurs, such as a base station fails (base station internal processing error, etc.) or the base station does not completely comply with the protocol, the E-rabreleselist cell carries an abnormality, for example: when the eNB reports the E-RAB release result by using the E-RABRELESERESPONSE message, the E-RAB which is successfully released is carried in the E-RABRELESEListIE, and the E-RAB which is failed to be released is carried in the E-RABFaideleaseListIE, but the sum of the quantity of the E-RARAB in the E-RABRELESEList cell and the quantity of the E-RAB in the E-RABFaideletedReleaseList cell is not equal to the quantity of the E-RAB which is issued by the core network.

When the above situation occurs, the fault tolerance of the core network may be reduced, and the core network may be hung up due to too much load.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

Example one

Referring to fig. 1, a flowchart illustrating steps of a bearer release method provided in an embodiment of the present application is shown, and as shown in fig. 1, the bearer release method may specifically include the following steps:

step 101: sending a bearer release message to a base station; the bearer release message includes a first number of radio access bearers to be released.

The embodiment of the application can be applied to a scene that after the base station releases the radio access bearer, the release result contains the radio access bearer which is successfully released and the radio access bearer which is failed to be released at the same time, but when the radio access bearer which is not reported exists, the radio access bearer which is not reported is processed.

The embodiment can be applied to a core network.

The first number is the number of the radio access bearers which are issued by the core network and need to be released by the base station.

The bearer release message is a message which is issued by the core network to the base station and used for releasing a radio access bearer (E-RAB). The bearer release message contains the number of E-RABs to be released.

When the core network needs the base station to release the E-RAB, a bearer release message (E-rabeleasecommand) may be sent to the base station, and the E-rabeleasecommand carries the number of the E-RAB that the base station needs to release, that is, the first number.

After sending the bearer release message to the base station, step 102 is performed.

Step 102: and acquiring a bearer release response message returned by the base station according to the bearer release message.

The bearer release response message refers to a response message returned by the base station to the core network after the E-RAB is released, i.e., an E-rabrellesesoponsense message (E-RAB release response message).

After receiving the E-rabrellesequence message sent by the core network, the eNB processes the accessed E-RAB to generate a response message for releasing the E-RAB, i.e., an E-rabrellesesponse message, and further, the eNB may report the E-rabrellesesponse message to the core network.

After acquiring the bearer release response message returned by the base station according to the bearer release message, step 103 is executed.

Step 103: and determining a second number of the wireless access bearers reported by the base station according to the bearer release response message.

The second number is the number of released E-RABs reported by the base station. In this embodiment, the second number may be the number of E-RABs successfully released and reported by the base station, may also be the number of E-RABs failed to be released and reported by the base station, and may also be the total number of E-RABs successfully released and E-RABs failed to be released and reported by the base station.

The bearer release response message reported by the base station may only include a response message of the E-RAB that is successfully released, that is, the E-raberelesense message sent by the eNB to the core network includes the E-rabereleselist IE, the E-RAB in the IE is taken as the E-RAB that is successfully released by the base station, and the number of E-RABs included in the E-raberelesense is taken as the second number.

The bearer release response message reported by the base station may only include the response message of the E-RAB that failed to be released, that is, the E-raberedeleaselistie is included in the E-rabeleaseresponse message sent by the eNB to the core network, the E-RAB in the IE is taken as the E-RAB that failed to be released by the base station, and the number of the E-RAB included in the E-rabeleaseresponse is taken as the second number.

When the bearer release response message reported by the base station simultaneously contains the response message of the E-RAB which is successfully released and the response message of the E-RAB which is unsuccessfully released, namely the E-RABRELEASELESSLIE and the E-RABFaidedToReleaseListIE are simultaneously contained in the E-RABRELESERESPONSE message sent by the eNB to the core network, the E-RABs in the two IEs respectively represent the E-RAB which is successfully released and the E-RAB which is unsuccessfully released, and then the total number of the E-RABs which are successfully released and the E-RABs which are unsuccessfully released is taken as the second number.

After determining the second number of radio access bearers reported by the base station according to the bearer release response message, step 104 is executed.

Step 104: and under the condition that the first number is not equal to the second number, releasing other radio access bearers except the radio access bearer of the second number in the radio access bearers of the first number according to a preset bearer release rule.

After the first number and the second number are obtained, whether the first number and the second number are the same or not can be judged, and when the first number and the second number are equal, it indicates that the base station reports the release results of all the E-RABs, wherein the release results may include successful release and/or failed release, and the core network performs processing according to the existing flow.

And when the first number is not equal to the second number, the reporting result of the base station may be incomplete due to difference in implementation and protocol or other problems (such as internal errors of the base station, etc.), at this time, the E-RAB reported by the base station may be processed according to the existing flow, and the E-RABs not reported by the base station (i.e., other E-RABs except for the second number in the first number) may be processed.

In this embodiment, it is fully considered that when a failure occurs in the base station (for example, an internal processing error of the base station, etc.) or the base station does not completely comply with the protocol, which causes an abnormality in an E-rablelesenstest cell carried in an E-rablelesesoponsense message returned by the base station, the radio access bearer that is not reported by the base station is released to avoid the resource of the core network from being hung.

The bearer release method provided in this embodiment of the present application includes sending a bearer release message to a base station, where the bearer release message includes a first number of radio access bearers that need to be released, acquiring a bearer release response message returned by the base station according to the bearer release message, determining a second number of radio access bearers reported by the base station according to the bearer release response message, and releasing other radio access bearers except for the radio access bearers of the second number in the radio access bearers of the first number according to a preset bearer release rule when the first number and the second number are not equal to each other. In the embodiment of the application, when the base station fails (such as processing errors in the base station) or the base station does not completely conform to the protocol, and the E-RABRELEASeList cell in the E-RABRELESERESPONSE message returned by the base station carries the exception, the radio access bearer which is not reported by the base station is released, so that the fault tolerance of the core network can be enhanced and the resources of the core network are prevented from being hung up when the base station side is abnormal.

Example two

Referring to fig. 2, a flowchart illustrating steps of another bearer release method provided in an embodiment of the present application is shown, and as shown in fig. 2, the bearer release method may specifically include the following steps:

step 201: sending a bearer release message to a base station; the bearer release message includes a first number of radio access bearers to be released.

The embodiment of the application can be applied to a scene that after the base station releases the radio access bearer, the release result contains the radio access bearer which is successfully released and the radio access bearer which is failed to be released at the same time, but when the radio access bearer which is not reported exists, the radio access bearer which is not reported is processed.

The embodiment can be applied to a core network.

The first number is the number of the radio access bearers which are issued by the core network and need to be released by the base station.

The bearer release message is a message which is issued by the core network to the base station and used for releasing a radio access bearer (E-RAB). The bearer release message contains the number of E-RABs to be released.

When the core network needs the base station to release the E-RAB, a bearer release message (E-rabeleasecommand) may be sent to the base station, and the E-rabeleasecommand carries the number of the E-RAB that the base station needs to release, that is, the first number.

After sending the bearer release message to the base station, step 202 is performed.

Step 202: and acquiring a bearer release response message returned by the base station according to the bearer release message.

The bearer release response message refers to a response message returned by the base station to the core network after the E-RAB is released, i.e., an E-rabrelleasepressense (E-RAB release response) message.

After receiving the E-rabbeteleasecommand message sent by the core network, the eNB processes the accessed E-RAB to generate an E-rabepresensense message, i.e., an E-rabereesense, and further, the eNB may report the E-rabereesense message to the core network.

The response message of the E-RAB which is successfully released may be only contained in the bearer release response message, the response message of the E-RAB which is failed to be released may be only contained in the bearer release response message, and the response message of the E-RAB which is successfully released and the response message of the E-RAB which is failed to be released may be simultaneously contained in the bearer release response message. In particular, it may be determined according to actual conditions.

After acquiring the bearer release response message returned by the base station according to the bearer release message, step 203 is executed, or step 205 is executed, or step 207 is executed.

Step 203: and when the bearer release response message only carries the bearer release success list, acquiring the successfully released radio access bearer contained in the bearer release success list.

When the E-rabelleesesoponse message is received, the bearer release list carried in the E-rabelleesesopense message may be acquired, and when the E-rabelleesesopense message only includes the bearer release success list (i.e., the E-rabelleesesisie), the E-RAB included in the E-rabellessesisie may be acquired, which is successfully released.

After acquiring the radio access bearer successfully released included in the bearer release success list, step 204 is executed.

Step 204: and taking the number of the radio access bearers successfully released as a second number.

After the successfully released E-RABs contained in the E-rabreleseListie are obtained, the number of the E-RABs contained in the E-rabreleseListie, that is, the number of the successfully released E-RABs, may be counted, and the number of the successfully released E-RABs is taken as the second number.

Step 205: and when the bearer release response message only carries a bearer release failure list, acquiring the radio access bearer which is contained in the bearer release failure list and fails to be released.

When the E-rabeleaseresponse message is received, the bearer release list carried in the E-rabeleaseresponse message may be acquired, and when the E-rabeleaseseresense message only includes the bearer release failure list (i.e., E-rabfabailtedtreleaselistie), the E-rababerrationfailed release list included in the E-rababeilaidedeletedreelistie may be acquired.

Step 206: and taking the number of the radio access bearers with the failed release as a second number.

After the E-RABs that are contained in the E-rabfabailendtoredelelistie and failed to be released are obtained, the number of the E-RABs contained in the E-rabfabacedtoredelelistie, that is, the number of the E-RABs that failed to be released, may be counted, and the number of the E-RABs that failed to be released is taken as the second number.

Step 207: and when the bearer release response message carries both the bearer release success list and the bearer release failure list, acquiring the radio access bearer successfully released and contained in the bearer release success list and the radio access bearer unsuccessfully released and contained in the bearer release failure list.

When the E-rabeleaseresponse message is received, the bearer release list carried in the E-rabeleaseresponse message may be acquired, and when the E-rabeleaseseresense message includes both the bearer release success list (i.e., E-rabeleaselist ie) and the bearer release failure list (i.e., E-rabfeledeleaselist ie), the E-RAB included in the E-rabeleaselist ie and the E-RAB included in the E-rabelesedurelist ie and having a release failure may be acquired.

Step 208: and taking the total number of the radio access bearers with successful release and the radio access bearers with failed release as a second number.

After the E-RABs included in the E-rabreleseListie and successfully released E-RABs included in the E-rabreleseListie and the E-RABs included in the E-rabreleseListie and failed to release are obtained, the number of the E-RABs included in the E-rabreleseListie and the number of the E-RABs included in the E-rabfelodidereseListie, that is, the number of the E-RABs successfully released and the number of the E-RABs failed to release, may be counted, and the sum of the number of the E-RABs successfully released and the number of the E-RABs failed to release is taken as the second number.

Step 209: starting a timer in case said first number and said second number are not equal.

After obtaining the second number corresponding to the radio access bearer successfully released and the radio access bearer failed to be released, it may be compared whether the first number and the second number are equal.

After the first number and the second number are obtained, whether the first number and the second number are the same or not can be judged, and when the first number and the second number are equal, it indicates that the base station reports the release results of all the E-RABs, wherein the release results may include successful release and/or failed release, and the core network performs processing according to the existing flow.

When the first number is not equal to the second number, it indicates that the reporting result of the base station may be incomplete due to difference in implementation and protocol or other problems (e.g., internal errors of the base station, etc.), at this time, the E-RAB reported by the base station may be processed according to the existing flow, and at this time, the core network may start a preset timer to time.

After the timer is started, step 210 is performed.

Step 210: deleting the other radio access bearer in case the timer expires.

When the timer is overtime, other radio access bearers can be deleted directly, the core network starts the timer (the timer has a default value and supports configuration), and after the timer is overtime, the E-RAB which is not reported by the base station in the core network is deleted, so that the resources of the core network are ensured not to be hung up.

Step 211: and under the condition that the first number and the second number are not equal, generating a target bearer release message corresponding to the other radio access bearers, and starting a counter.

When the first number is not equal to the second number, it indicates that the reporting result of the base station may be incomplete due to difference in implementation and protocol or other problems (such as internal errors of the base station, etc.), and at this time, the E-RAB that fails to be released and reported by the base station may be processed according to the existing flow.

The target bearer release message is generated by the core network aiming at the E-RAB which is not reported by the base station and is used for indicating the base station to release the E-RAB which is not reported.

When the first number is not equal to the second number, the core network may generate a target bearer release message corresponding to another radio access bearer for an E-RAB not reported by the base station (i.e., another radio access bearer), and start a preset counter, where the counter may count the number of times of sending the target bearer release message, and further, the core network may send the target bearer release message to the base station, where the target bearer release message includes the E-RAB not reported by the base station to instruct the base station to release the E-RAB not reported.

Step 212 is performed after generating a target bearer release message for the other radio access bearer and starting the counter.

Step 212: and deleting at least one radio access bearer when the counted times of the counter reach the set times and at least one radio access bearer in the other radio access bearers not reported by the base station exists.

When the counted times of the counter reaches the set times and at least one of the other radio access bearers which are not reported by the base station still exists, the core network can forcibly release the flow, namely delete at least one radio access bearer in the core network, so that the resources of the core network are not hung up.

The bearer release method provided in this embodiment of the present application includes sending a bearer release message to a base station, where the bearer release message includes a first number of radio access bearers that need to be released, acquiring a bearer release response message returned by the base station according to the bearer release message, determining a second number of radio access bearers reported by the base station according to the bearer release response message, and releasing other radio access bearers except for the radio access bearers of the second number in the radio access bearers of the first number according to a preset bearer release rule when the first number and the second number are not equal to each other. In the embodiment of the application, when the base station fails (such as processing errors in the base station) or the base station does not completely conform to the protocol, and the E-RABRELEASeList cell in the E-RABRELESERESPONSE message returned by the base station carries the exception, the radio access bearer which is not reported by the base station is released, so that the fault tolerance of the core network can be enhanced and the resources of the core network are prevented from being hung up when the base station side is abnormal.
