Description

VOLTE service processing method and device, electronic equipment and storage medium
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a VOLTE service processing method, a VOLTE service processing device, electronic equipment and a storage medium.
Background
Voice Over LTE (Voice Over LTE, Voice service based on LTE network) is an IP (Internet Protocol, Protocol for interconnection between networks) data transmission technology, and all services are carried on a 4G network, so that unification of data and Voice services in the same network can be achieved.
VoLTE is a voice over IP service, but is more sensitive to throughput, latency, dropped calls, etc. than data services. There are always some cells in the network where VoLTE is of poor quality and cannot be optimized, and UE (User Equipment) is very poorly aware of using VoLTE service in these cells.
Fig. 1 shows a basic flow of the prior art in which a UE can normally use VoLTE service.
As shown in fig. 1, it can be seen that the UE can normally use the basic condition of VoLTE, and the UE subscription data, the UE, the eNodeB (base station), and the MME (Mobility Management Entity) are required to support VoLTE function, and it is only when all the requirements are met that the VoLTE service can be normally registered and used.
Specifically, a user opens a VoLTE subscription, after the power-on attachment is successful, the UE separately initiates a PDN (Public Data Network) connection request of an APN (Access Point Name, IP Multimedia Subsystem), successfully establishes an IMS signaling default bearer of QCI (Quality of Service Class Identifier) 5, and then initiates a registration request of the IMS domain.
On the basis of UE subscription data and VoLTE function support, whether the UE can use the VoLTE service or not can be controlled by the MME at the network side
Fig. 2 shows a signaling interaction diagram for controlling VOLTE service by MME in the prior art.
The MME has a VoLTE service function switch, and when the VoLTE service function of the MME is closed, UE (user equipment) cannot establish IMS (IP multimedia subsystem) signaling default bearer for user bearer SIP (session initiation protocol) signaling, namely the UE cannot register the VoLTE service, so that all the UE accessed through the MME cannot register the VoLTE service, and cell dimension management and control cannot be realized.
As shown in fig. 2, the control point in this scheme is step 8, the MME issues Attach accept \ Active _ default _ EPS _ bearer _ context _ request (Attach accept \ activate default EPS bearer context request) to the UE, indicating that the network does not support VoLTE service, so the terminal will not initiate an establishment request of the IMS PDN, that is, the UE cannot establish an IMS signaling default bearer for carrying SIP (Session Initiation Protocol) signaling.
The existing network MME adopts a networking form of MME POOL (MME POOL), the MME POOL is physically a group of MME, and when the request of each eNodeB comes, as long as the request is assigned to the POOL, the internal application mechanism of the POOL can allocate which MME the eNodeB accesses, that is, the existing network eNodeB accesses the MME POOL.
If the VoLTE function of a certain MME in the POOL is separately turned off, all cells under the MME service cannot be used, and it is impossible to control all users under a certain cell to use VoLTE services. However, closing the VoLTE functions of all MMEs in the POOL will result in that the whole network cannot use VoLTE services.
Therefore, in the prior art, the VoLTE service of the poor quality cell is controlled by the MME, which cannot be accurately controlled to the cell level, and cannot realize that the VoLTE service is specifically prohibited from being used by the user in a certain poor quality cell.
Fig. 3 shows a signaling interaction diagram for controlling VOLTE service through enodebs in the prior art.
The eNodeB has a VoLTE function switch, and closes the VoLTE function of the eNodeB, and a user can normally register VoLTE service under the eNodeB, but when initiating a call, the eNodeB cannot establish a dedicated bearer with QCI ═ 1\2, and will carry Cause37 in a message E _ rabetupresponse: and rejecting the call by using the No-supported-QCI-value error code, wherein a control point of the scheme is the 18 th step of the signaling flow, the scheme can realize the control at the eNodeB level, but can cause call drop of a user and influence the perception of the user.
At present, no corresponding method exists in the prior art to simultaneously solve the problems of low precision of forbidding the VOLET service and no influence on user perception.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
Fig. 4 shows a flowchart of a VOLTE service processing method according to an embodiment of the present invention.
As shown in fig. 4, the method provided in the embodiment of the present invention specifically includes the following steps:
11. and the receiving end receives VOLTE service registration information sent by the sending end, wherein the VOLTE service registration information is used for requesting VOLTE service registration in a cell accessed by the UE and comprises an identifier of the cell accessed by the UE.
Optionally, the UE initiates establishment of a 4G bearer first, and initiates a VOLTE service registration process after the 4G bearer is successfully established.
In this embodiment, signaling interacted between network elements in the procedure of registering the VOLTE service by the UE may be collectively referred to as VOLTE service registration message.
Optionally, the UE interacts with the base station to trigger the sending end to send the VOLTE service registration message to the receiving end.
Optionally, the VOLTE service registration message includes an identification of a Cell, such as an ECGI (E-UTRAN Cell Global Identifier, evolved-universal mobile telecommunications system terrestrial radio access network Cell Global Identifier), to which the UE accesses, so as to request the UE to register the VOLTE service in the Cell.
12. And if the receiving end judges that the identification of the cell is matched with the pre-stored identification data of the cell in which the VOLTE service is forbidden to be registered, returning a failure response to the transmitting end so as to forbid the UE from registering the VOLTE service in the accessed cell.
Optionally, the receiving end receives the VOLTE service registration message sent by the sending end, and acquires the identifier of the cell.
Optionally, the receiving end prestores identification data of a cell for which registration of the VOLTE service is prohibited.
Optionally, the identification data of the cell in which the VOLTE service is prohibited from being registered is an identification list including a plurality of cells in which the VOLTE service is prohibited from being registered.
Optionally, the identification data of the cell in which the VOLTE service is prohibited to be registered is obtained by using the prior art, so that the receiving end knows which cells are prohibited to register the VOLTE service in advance.
And the receiving terminal matches the identification of the cell acquired from the VOLTE service registration message with the identification data of the cell in which the VOLTE service is forbidden to be registered, and searches whether the cell is the cell in which the VOLTE service is forbidden to be registered.
If the identification data of the cell in which the VOLTE service is forbidden to be registered has the identification which is the same as the identification of the cell, the receiving end determines that the cell is the cell in which the VOLTE service is forbidden to be registered, and returns a failure response to the transmitting end, so that the UE cannot register the VOLTE service in the cell which is accessed currently.
Optionally, after receiving the failure response, the sending end forwards the failure response to the UE, and after learning that the VoLTE service registration fails, the UE performs a CSFB (Circuit Switched Fallback ) procedure, and falls back from 4G to 2G to use a 2G voice service.
It can be understood that in the practical application process, the situation of the existing network is complex, and sometimes individual control needs to be carried out on the specified cells.
For example, the upper level indicates that VoLTE service restriction is performed on a specified cell, or cannot be optimized due to poor communication quality of a certain cell, and the minimum communication requirements, such as smoothness of data service and voice service, should be preferentially ensured, so that advanced services, such as VoLTE service restriction, need to be performed on the cell.
In this embodiment, the identification data of the cell in which the VOLTE service is prohibited to be registered is prestored by the receiving end, after receiving the VOLTE service registration message, the identification of the cell to which the UE is accessed is matched with the identification data of the cell in which the VOLTE service is prohibited to be registered, and if the identification of the cell to which the UE is currently accessed is matched with one of the identification data of the cells in which the VOLTE service is prohibited to be registered, a failure response is returned.
The VOLTE service processing method provided by this embodiment has at least the following technical effects:
the identification data of the cell in which the VOLTE service is forbidden to be registered is prestored through the receiving terminal, after the VOLTE service registration message is received, if the receiving terminal judges that the identification of the cell accessed by the UE is matched with the identification data of the cell in which the VOLTE service is forbidden to be registered, the UE is forbidden to register the VOLTE service in the currently accessed cell, and therefore the processing precision of the VOLTE service forbidden to be registered is improved to the cell level without influencing the user perception.
Fig. 5 shows a signaling interaction diagram of a VOLTE service processing method according to another embodiment of the present invention.
As shown in fig. 5, on the basis of the foregoing embodiment, the receiving end and the transmitting end in the VOLTE service processing method according to another embodiment of the present invention may have multiple types, and this embodiment takes one of the modes as an example for description.
In this embodiment, the receiving end is an MME (Mobility Management Entity), and the transmitting end is a UE.
Correspondingly, the step 11 is specifically:
and the MME receives an IMS PDN connection request sent by the UE, wherein the PDN connection request is used for the UE to request IMS network connection and comprises the identification of the cell accessed by the UE.
In this embodiment, signaling interacted between network elements in the procedure of registering the VOLTE service by the UE may be collectively referred to as VOLTE service registration message.
After the UE is successfully attached, the UE sends a VOLTE service registration message to the base station, for example, a signaling 14, the VOLTE service registration message can be an IMS PDN connection request, and the base station transparently transmits the IMS PDN connection request to an MME;
optionally, the PDN connection request includes an APN and an identity of a cell, where APN ═ ims.
Optionally, different APNs correspond to different PDN networks, typically defined by an operator, and when an APN is IMS, this indicates a request for an IMS network connection to access the IMS network.
Correspondingly, the step 12 is specifically:
and if the MME judges that the identification of the cell is matched with the pre-stored identification data of the cell in which the VOLTE service is forbidden to be registered, returning a failure response to the base station so as to forbid the UE from registering the VOLTE service in the accessed cell.
Optionally, the MME receives the IMS PDN connection request sent by the UE, and acquires the identity of the cell.
Optionally, the MME prestores identification data of a cell for which registration of the VOLTE service is prohibited.
Optionally, the identification data of the cell in which the VOLTE service is prohibited to be registered is obtained by using the prior art, so that the MME knows in advance which cells are prohibited to register the VOLTE service.
And the MME matches the identification of the cell acquired from the IMS PDN connection request with the identification data of the cell in which the VOLTE service is forbidden to be registered, and searches whether the cell is the cell in which the VOLTE service is forbidden to be registered.
As in signaling 15, if the identity data of the cell in which the VOLTE service is prohibited from being registered includes an identity that is the same as the identity of the cell and the APN is equal to IMS, the MME determines that the cell is the cell in which the VOLTE service is prohibited from being registered, returns an IMS PDN reject response to the base station, and forwards the response to the UE from the base station.
Optionally, the IMS PDN connection request and the PDN reject response are both NAS (Non-access stratum) messages.
Optionally, the flow of the access stratum refers to a flow in which a Radio Network Controller (RNC) and a base station (NodeB) of the Radio access stratum need to participate in processing; the procedure of the non-access stratum refers to a signaling procedure that the UE and the CN (Core Network ) need to process, and other Network elements such as (RNC, NodeB) only perform transparent transmission and do not need processing.
Optionally, the UE receives a PDN rejection response through the base station, learns that the PDN network rejects connection and the VoLTE service registration fails, and drops back to 2G to use the 2G voice service.
Other steps of this embodiment are similar to those of the previous embodiment, and are not described again in this embodiment.
The VOLTE service processing method provided by this embodiment has at least the following technical effects:
the method comprises the steps that identification data of a cell in which VOLTE service registration is forbidden are prestored by an MME, and after a PDN connection request sent by UE is received, if the fact that the identification of the cell accessed by the UE is matched with the identification data of the cell in which the VOLTE service registration is forbidden is judged and known, the UE is forbidden to register the VOLTE service in the currently accessed cell, so that the MME realizes the VOLTE service restriction of a cell level.
Fig. 6 shows a signaling interaction diagram of a VOLTE service processing method according to another embodiment of the present invention.
As shown in fig. 6, on the basis of the foregoing embodiment, the receiving end and the transmitting end in the VOLTE service processing method according to another embodiment of the present invention may have multiple types, and this embodiment takes one of the modes as an example for description.
In this embodiment, the receiving end is a gateway, and the sending end is an MME.
Correspondingly, the step 11 is specifically:
and the gateway receives a session creating request sent by the MME, wherein the session creating request is used for a session of a UE request for creating an IMS PDN and comprises an identification of a cell accessed by the UE.
In this embodiment, signaling interacted between network elements in the procedure of registering the VOLTE service by the UE may be collectively referred to as VOLTE service registration message.
Optionally, as in signaling 15, after receiving the PDN connection request, the MME sends a VOLTE service registration message to the gateway, where the VOLTE service registration message is a session creation request, and is used to request to create a session of the IMS, and includes an APN and an identifier of a cell, where the APN is IMS.
Optionally, the gateway may be adjusted according to an actually applied network architecture.
For example, the gateway may be any one of:
SGW (Serving GateWay), PGW (Public Data Network GateWay), and SAEGW (System Architecture Evolution GateWay, usually two Network elements of S-GW and P-GW are combined), which are different according to the Network Architecture of the application.
Correspondingly, the step 12 is specifically:
and if the gateway judges that the identification of the cell is matched with the pre-stored identification data of the cell in which the VOLTE service is forbidden to be registered, returning a failure response to the MME so as to forbid the UE from registering the VOLTE service in the accessed cell.
Optionally, the MME receives the session creation request sent by the base station, and acquires the identifier of the cell.
Optionally, the gateway stores in advance identification data of a cell for which registration of the VOLTE service is prohibited.
Optionally, the identification data of the cell in which the VOLTE service is prohibited to be registered is obtained by using the prior art, so that the gateway knows which cells are prohibited to register the VOLTE service in advance.
And the gateway matches the identification of the cell acquired from the session creation request with the identification data of the cell in which the VOLTE service is forbidden to be registered, and searches whether the cell is the cell in which the VOLTE service is forbidden to be registered.
As in signaling 16, if the identifier data of the cell in which the VOLTE service is prohibited from being registered includes an identifier that is the same as the identifier of the cell and the APN is equal to IMS, the gateway determines that the cell is the cell in which the VOLTE service is prohibited from being registered, and returns a creation failure response to the MME.
Optionally, the MME receives the creation failure response, and generates a PDN rejection response of the corresponding PDN connection request.
And the UE receives the PDN rejection response, learns that the PDN network rejects connection and the VoLTE service registration fails, and falls back to 2G to use the 2G voice service.
Other steps of this embodiment are similar to those of the previous embodiment, and are not described again in this embodiment.
The VOLTE service processing method provided by this embodiment has at least the following technical effects:
the method comprises the steps that identification data of a cell for forbidding VOLTE service registration are prestored through a gateway, after a session creation request sent by an MME is received, if the fact that the identification of the cell accessed by UE is matched with the identification data of the cell for forbidding VOLTE service registration, which is prestored, is judged, the UE is forbidden to register the VOLTE service in the cell accessed at present, and therefore VOLTE service restriction of a cell level is achieved through the gateway.
Fig. 7 shows a signaling interaction diagram of a VOLTE service processing method according to another embodiment of the present invention.
As shown in fig. 7, on the basis of the foregoing embodiment, the receiving end and the transmitting end in the VOLTE service processing method according to another embodiment of the present invention may have multiple types, and this embodiment takes one of the modes as an example for description.
In this embodiment, the receiving end is a PCRF (Policy and Charging Rules Function), and the sending end is a gateway.
The embodiment of the invention provides that the VoLTE service Control can be realized based on PCC (Policy Control and Charging).
The PCC architecture maps QoS (Quality of Service) requirements of application-level session Service data flows to QoS requirements of IP-CAN (IP-Connectivity Access Network) bearer-level services to guarantee data transmission, and may also implement a charging function of a Service data flow level according to a charging policy of an operator.
At present, the PCC architecture at present mainly consists of PCRF and PCEF (Policy and Charging implementation Function).
The PCRF is a policy and charging control policy decision point for service data flow and IP bearer resources, and selects and provides available policy and charging control decisions for the PCEF.
Optionally, the gateway may be adjusted according to an actually applied network architecture.
For example, the gateway may be any one of:
SGW (Serving GateWay), PGW (Public Data Network GateWay), and SAEGW (System Architecture Evolution GateWay, usually two Network elements of S-GW and P-GW are combined), which are different according to the Network Architecture of the application.
Correspondingly, the step 11 is specifically:
the method comprises the steps that a PCRF receives a credit control request sent by a gateway, wherein the credit control request is used for UE to establish PCC rules of IMS signaling default load and comprises an identification of a cell accessed by the UE;
in this embodiment, signaling interacted between network elements in the procedure of registering the VOLTE service by the UE may be collectively referred to as VOLTE service registration message.
Optionally, after the UE successfully attaches, a PDN connection request is sent to the MME, where the PDN connection request includes an APN and an identifier of a cell, where the APN is ims, and the identifier of the cell is ECGI.
Optionally, after receiving the PDN connection request, the MME sends a session creation request to the gateway, where the session creation request is used to request to create a session of the IMS, and the session creation request includes an APN and an identifier of a cell, where the APN is IMS, and the identifier of the cell is ECGI.
Optionally, as in signaling 16, the gateway receives the create session request, and sends a VOLTE service registration message to the PCRF, where the VOLTE service registration message is a credit control request, and the credit control request is used to request to establish an IMS signaling default bearer and includes an identifier of the cell and a QCI, where the QCI is 5.
Optionally, the default bearer for IMS signaling is an IP transport channel defining attributes such as speed, delay, bit error rate, and the like.
Correspondingly, the step 12 is specifically:
and if the PCRF judges that the identification of the cell is matched with the pre-stored identification data of the cell in which the VOLTE service is forbidden to be registered, returning a failure response to the gateway so as to forbid the UE from registering the VOLTE service in the accessed cell.
Optionally, the PCRF receives the credit control request sent by the gateway, and obtains the identifier of the cell.
Optionally, the PCRF prestores identification data of a cell for which registration of the VOLTE service is prohibited.
Optionally, the identification data of the cell in which the VOLTE service is prohibited to be registered is obtained by using the prior art, so that the PCRF knows in advance which cells are prohibited to register the VOLTE service.
And the PCRF matches the identification of the cell acquired from the credit control request with the identification data of the cell in which the VOLTE service is forbidden to be registered, and searches whether the cell is the cell in which the VOLTE service is forbidden to be registered.
If the identity data of the cell for which the VOLTE service is prohibited from being registered includes an identity that is the same as the identity of the cell and the QCI is 5, the PCRF determines that the cell is the cell for which the VOLTE service is prohibited from being registered, and returns a failure response to the gateway, as in signaling 17.

Fig. 9 is a schematic structural diagram of a VOLTE service processing apparatus according to yet another embodiment of the present invention.
Referring to fig. 9, on the basis of the foregoing embodiment, the VOLTE service processing apparatus provided in this embodiment includes a receiving module 91 and a determining module 92, where:
the receiving module 91 is configured to receive a VOLTE service registration message sent by a sending end, where the VOLTE service registration message is used to request registration of a VOLTE service in a cell to which the UE is accessed and includes an identifier of the cell to which the UE is accessed; the determining module 92 is configured to, if it is determined that the identifier of the cell matches the pre-stored identifier data of the cell for which the registration of the VOLTE service is prohibited, return a failure response to the sending end to prohibit the UE from registering the VOLTE service in the accessed cell.
Optionally, the UE initiates establishment of a 4G bearer first, and initiates a VOLTE service registration process after the 4G bearer is successfully established.
In this embodiment, signaling interacted between network elements in the procedure of registering the VOLTE service by the UE may be collectively referred to as VOLTE service registration message.
Optionally, the UE interacts with the base station to trigger the sending end to send a VOLTE service registration message to the receiving module 91.
Optionally, the receiving module 91 receives the VOLTE service registration message sent by the sending end, and acquires the identifier of the cell.
Optionally, the determining module 92 stores in advance identification data of a cell for which registration of the VOLTE service is prohibited.
Optionally, the identification data of the cell in which the VOLTE service is prohibited from being registered is an identification list including a plurality of cells in which the VOLTE service is prohibited from being registered.
The determining module 92 matches the identifier of the cell obtained from the VOLTE service registration message with the identifier data of the cell in which the VOLTE service is prohibited to be registered, and searches whether the cell is the cell in which the VOLTE service is prohibited to be registered.
If the identification data of the cell in which the VOLTE service is prohibited from being registered includes an identification identical to the identification of the cell, the determining module 92 determines that the cell is the cell in which the VOLTE service is prohibited from being registered, and returns a failure response to the transmitting end, so that the UE cannot register the VOLTE service in the cell currently accessed.
Optionally, after the registration of the VoLTE service fails, the UE performs a CSFB (Circuit Switched Fallback) procedure, and falls back from 4G to 2G to use the 2G voice service, so as to avoid a call drop, thereby maintaining connectivity of the call.
It can be understood that in the practical application process, the situation of the existing network is complex, and sometimes individual control needs to be carried out on the specified cells.
For example, the upper level indicates that VoLTE service restriction is performed on a specified cell, or cannot be optimized due to poor communication quality of a certain cell, and the minimum communication requirements, such as smoothness of data service and voice service, should be preferentially ensured, so that advanced services, such as VoLTE service restriction, need to be performed on the cell.
In this embodiment, the identification data of the cell in which the VOLTE service is prohibited to be registered is pre-stored by the determining module 92, after receiving the VOLTE service registration message, the identification of the cell to which the UE is accessed is matched with the identification data of the cell in which the VOLTE service is prohibited to be registered, if the identification of the cell to which the UE is currently accessed is matched with one of the identification data of the cell in which the VOLTE service is prohibited to be registered, a failure response is returned, and due to the pre-stored identification data of the cell in which the VOLTE service is prohibited to be registered, the VOLTE service is prohibited to be registered by the UE in some cells, so that the processing accuracy of the VOLTE service prohibited to be registered is improved to a cell level.

The determining module 92 is further configured to, if it is determined that the identifier of the cell matches the pre-stored identifier data of the cell for which the registration of the VOLTE service is prohibited, return a failure response to the base station to prohibit the UE from registering the VOLTE service in the accessed cell.
The determining module 92 matches the identifier of the cell obtained from the PDN connection request with the identifier data of the cell in which the VOLTE service is prohibited from being registered, and searches whether the cell is the cell in which the VOLTE service is prohibited from being registered.
As shown in fig. 5 signaling 15, if the identifier of the cell where the VOLTE service is prohibited from being registered is the same as the identifier of the cell, the determining module 92 determines that the cell is the cell where the VOLTE service is prohibited from being registered, returns a PDN reject response to the base station, and forwards the PDN reject response to the UE.
Optionally, the PDN connection request and the PDN rejection response are both NAS (Non-access stratum) messages.

The identification data of the cell in which the VOLTE service is forbidden to be registered is prestored through a judging module of the MME, and after a PDN connection request sent by the UE is received, if the identification of the cell accessed by the UE is judged to be matched with the identification data of the cell in which the VOLTE service is forbidden to be registered, the UE is forbidden to register the VOLTE service in the currently accessed cell, so that the VOLTE service limitation of the cell level is realized through the judging module of the MME.

The receiving module 91 receives a create session request sent by the MME, where the create session request is used for a session in which the UE requests to create an IMS PDN and includes an identity of a cell to which the UE accesses.
As shown in signaling 15 of fig. 6, after receiving the PDN connection request, the receiving module 91 sends a VOLTE service registration message to the gateway, where the VOLTE service registration message is a session creation request for requesting to create a session of the IMS.

If the judgment module 92 judges that the cell identifier matches with the pre-stored cell identifier data for prohibiting registration of the VOLTE service, a failure response is returned to the MME to prohibit the UE from registering the VOLTE service in the accessed cell.
As shown in signaling 16 of fig. 6, if the identifier data of the cell in which the VOLTE service is prohibited from being registered includes an identifier that is the same as the identifier of the cell, the determining module 92 determines that the cell is the cell in which the VOLTE service is prohibited from being registered, and returns a create failure response to the MME.
Optionally, the MME receives the creation failure response, and generates a PDN rejection response of the corresponding PDN connection request.

If the judgment module 92 judges that the cell identifier matches with the pre-stored cell identifier data for prohibiting registration of the VOLTE service, a failure response is returned to the gateway to prohibit the UE from registering the VOLTE service in the accessed cell.
As shown in fig. 7 signaling 17, if the identifier data of the cell in which the VOLTE service is prohibited from being registered includes an identifier that is the same as the identifier of the cell, the determining module 92 determines that the cell is the cell in which the VOLTE service is prohibited from being registered, and returns a failure response to the gateway.
