Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the LTE system, a traffic flow with the same quality of service (QOS) latency between a UE and a public data network (PDN-Gateway/P-GW) is called an EPS (evolved packet system, EPS) bearer. I.e. EPS bearers can be guaranteed specifically for providing some characteristic QOS transport between the UE and the PDN. The EPS bearer is divided into a default bearer and a dedicated bearer.

The default bearer (default EPS bearer) is a user bearer for data and signaling that satisfies the default QOS. The default bearer is to improve user experience and reduce the time delay for establishing a service, and when the UE and the network complete attachment, the established bearer may be transmitted using the default bearer when the UE has a small amount of data to transmit.

Dedicated bearers (dedicated EPS bearers) are established in order to provide certain QoS transmission requirements (the default bearer cannot be met). For example, the UE has a need for large data transfer. Wherein the QoS of the dedicated bearer is more demanding than the QoS of the default bearer. The dedicated bearer is associated with an Uplink (UL) Traffic Flow Template (TFT) at the UE and a Downlink (DL) TFT at the PDN GW, which TFTs contain traffic flow filters that can only match packets that meet certain criteria.

A voice over long-term evolution (VOLTE) Bearer supports communication services such as high-definition voice and high-definition video, and is an end-to-end audio and video scheme of a Bearer (Bearer) network formed in an Evolved Packet System (EPS) of an LTE network. The protocol specification of the VOLTE, voice service and video service in the VOLTE, and protocol signaling for processing the VOLTE are all established on various bearers of the LTE network. The difference in bearers is mainly represented by the difference in QOS Class Identifier (QCI) and quality of service (QOS) scale value.

It should be noted that the TFT includes one or more downlink filters, and the TFT also includes zero or more uplink filters, where the TFT may include filters that are common to both uplink and downlink.

In the embodiment of the present application, a conflicting upstream filter in a TFT of a voice-only bearer or a conflicting upstream filter in a TFT of a video-only bearer is deleted, that is, one upstream filter is deleted. If the count of the upstream filter causing the voice-only bearer or the video-only bearer is zero after the deletion, that is, the filter causing the voice-only bearer or the video-only bearer does not have the upstream filter, the road bearer still needs to go off the activation flow, thereby causing a call drop or a video call to fall back to the voice call.

Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a process of establishing a dedicated bearer for a video call. As shown in fig. 1, the flow diagram of the video call establishing the dedicated bearer includes steps 101 to 111.

Step 101, user Equipment (UE) registers LTE.

Specifically, before a video call, the UE needs to attach to a 4G core (EPC) network, and establish an IP Multimedia Subsystem (IMS) default bearer, where the default bearer is used for carrying SIP signaling. SIP signaling is used to establish, modify and terminate multimedia sessions for two or more parties over an IP network.

The UE may be, for example, a mobile phone, a tablet computer, a wearable device, an in-vehicle device, an Augmented Reality (AR) \\ Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), and other electronic devices, where the UE is not limited in any way.

The network device may be an electronic device that directly communicates messages with the UE, and may illustratively be a base station (eNB).

Step 102, the UE initiates a video call.

Specifically, when a user wants to call VOLTE video call to another user, the user may call another UE through the UE. The UE may receive a video call instruction input by a user, and initiate a video call, that is, initiate a video call flow of a calling party. It should be noted that, in the embodiment of the present application, the UE refers to a UE of a calling party, and the present application does not limit the UE of a called party.

Step 103, the UE initiates a session request (invite).

Specifically, SIP includes invite signaling, inviting a user equipment of a user to join a session. The UE initiates a session invitation (invite), a network device. The INVITE message includes a call type, a number of a calling party and a called party, a media type and a code supported by a calling party, and the like.

Step 104, the network device responds to the session request (100).

Specifically, the UE initiates an invite of invite session, the UE higher-level protocol sends an invite message to the IMS, and when the IMS receives the invite message of the UE, the IMS starts paging and sends a message of 100 to the UE.

Step 105, the network device initiates a REQUEST to establish a voice-specific BEARER, which may be, for example, ACTIVATE DEDICATED EPS BEARER CONTEXT REQUEST, which is used to trigger the establishment of the voice-specific BEARER.

Step 106, the UE sends a message that the establishment of the voice-specific BEARER is completed, which may be ACTIVATE DEDICATED EPS BEARER CONTEXT ACCEPT, for example.

Specifically, in this scenario, the network device first initiates a REQUEST for establishing a voice specific BEARER, where the REQUEST for establishing may be ACTIVATE DEDICATED EPS BEARER CONTEXT REQUEST, and the UE establishes the voice specific BEARER and sends a message ACTIVATE DEDICATED EPS BEARER CONTEXT ACCEPT to establish the voice specific BEARER to the network device.

Illustratively, taking the network device as the eNB, the eNB may deliver the message ACTIVATE DEDICATED EPS BEARER CONTEXT REQUEST to the UE through the reconfiguration message.

Further, the UE successfully establishes the voice specific BEARER, returns a message rrcconnectionreconfiguration complete to the network device indicating that the voice specific BEARER was successfully established, and after sending the reconfiguration complete, the UE may send a message ACTIVATE DEDICATED EPS BEARER CONTEXT ACCEPT to the eNB.

It should be noted that a TFT is associated in the established voice specific bearer, where the TFT of the voice specific bearer includes one or more filters, and each filter corresponds to a unique filter identifier, where the identifier may be a value (precedence value) of a priority of the filter.

Step 107, the network device sends a request for establishing a video-specific bearer. The REQUEST may be, for example, ACTIVATE DEDICATED EPS BEARER CONTEXT REQUEST, which is used to set up a video-specific BEARER.

Step 108, the user equipment sends a message that the establishment of the video-specific BEARER is completed, and the message may be ACTIVATE DEDICATED EPS BEARER CONTEXT ACCEPT, for example.

The procedure for establishing the video dedicated bearer in step 107 to step 108 is the same as the procedure for establishing the audio dedicated bearer in step 105 to step 106, and is not described herein again.

It should be noted that, although the voice-specific bearer and the video-specific bearer are the same in the establishment process, the identification number (ID) of the specific bearer and the implementation manner adopted may be different. I.e. it is possible to distinguish between a voice specific bearer and a video specific bearer in the signalling field of the setup bearer. Taking QCI for voice-specific bearer and QCI for video-specific bearer as examples, QCI for voice-specific bearer =1 and QCI for video-specific bearer =2 are exemplified.

A TFT is also associated in the established video-specific bearer, where the TFT of the video-specific bearer includes one or more filters, each filter corresponds to a unique filter identifier, and the identifier may be a value (precedence value) of a priority of the filter.

Step 109, the UE triggers a deactivation process for the voice-specific bearer, wherein the UE sends a MODIFICATION REQUEST deactivation process, and the MODIFICATION REQUEST may be, for example, bearer resource MODIFICATION REQUEST.

Step 110, the network device sends a REQUEST to release the voice-specific BEARER, which may be, for example, DEACTIVATE EPS BEARER CONTEXT REQUEST.

Step 111, the UE sends a message that the release of the voice specific BEARER is complete, which may be DEACTIVATE EPS BEARER CONTEXT ACCEPT, for example.

Since the filter identifier existing in the TFT associated with the voice specific bearer is the same as the filter identifier existing in the TFT associated with the video specific bearer, that is, the value of the priority of one filter in the TFT associated with the voice specific bearer is the same as the value of the priority of one filter in the TFT associated with the video specific bearer, the voice specific bearer is triggered to be deactivated according to the protocol, thereby causing the voice bearer of the video call to be released. Therefore, the video call is interrupted, namely the video call is dropped, the call completing rate is low, and the call quality is low.

Specifically, according to the protocol, the UE sends a BEARER response MODIFICATION REQUEST message for modifying the BEARER to the network device, and then the network device starts a BEARER release procedure and sends a message DEACTIVATE EPS BEARER CONTEXT REQUEST to the UE. And the UE releases the voice special BEARER after receiving the reconfiguration message and returns a message DEACTIVATE EPS BEARER CONTEXT ACCEPT to the network equipment.

Illustratively, taking the network device as the eNB as an example, the UE sends a BEARER response MODIFICATION REQUEST message to the eNB, and the eNB starts a release procedure of the voice-specific BEARER and sends an rrcconnectionreception configuration to the UE, which includes a message DEACTIVATE EPS BEARER CONTEXT REQUEST. And the UE releases the voice special bearer after receiving the message. Further, the UE sends a return rrcconnectionreconfiguration complete message indicating that the radio BEARER release is successful, and returns a message DEACTIVATE EPS BEARER CONTEXT ACCEPT to the eNB to inform the completion of the voice specific BEARER deletion.

Referring to fig. 2, fig. 2 is a schematic flow chart illustrating another process for establishing a dedicated bearer for a video call. As shown in fig. 2, the flow diagram of the video call establishing dedicated bearer includes steps 201 to 211.

Step 201, UE registers LTE.

Step 202, the UE initiates a video call.

Step 203, the UE initiates a session request (invite).

Step 204, the network device responds to the session request (100).

The process in steps 201 to 204 is the same as the process in steps 101 to 104, and is not described here again.

Step 205, the network device sends a REQUEST for establishing a video-specific BEARER, which may be, for example, ACTIVATE DEDICATED EPS BEARER CONTEXT REQUEST, the REQUEST being used to trigger establishment of the video-specific BEARER.

In step 206, the UE sends a message that the establishment of the video-specific BEARER is completed, which may be ACTIVATE DEDICATED EPS BEARER CONTEXT ACCEPT, for example.

The procedure of establishing the video dedicated bearer in step 205 to step 206 is the same as that in step 107 to step 108, and is not described herein again.

Step 207, the network device sends a REQUEST to establish a voice specific BEARER, which may be, for example, ACTIVATE DEDICATED EPS BEARER CONTEXT REQUEST.

In step 208, the UE sends a message that the establishment of the voice-specific BEARER is completed, which may be ACTIVATE DEDICATED EPS BEARER CONTEXT ACCEPT, for example.

The procedure for establishing the video dedicated bearer in step 207-step 208 is the same as that in step 105-step 106, and is not described herein again.

It should be noted that the dedicated voice bearer may be established first, or the dedicated video bearer may be established first.

Step 209, the UE triggers a deactivation process for the voice specific BEARER, wherein the UE sends a MODIFICATION REQUEST deactivation process, and the MODIFICATION REQUEST may be, for example, BEARER RESOURCE MODIFICATION REQUEST.

Step 210, the network device sends a REQUEST to release the voice-specific BEARER, which may be, for example, DEACTIVATE EPS BEARER CONTEXT REQUEST.

In step 211, the UE sends a message that the release of the voice specific BEARER is complete, which may be DEACTIVATE EPS BEARER CONTEXT ACCEPT, for example.

The process of deactivating the dedicated voice bearer in step 209 to step 211 is the same as the process of activating the dedicated video bearer in step 109 to step 111, and is not described herein again.

It should be noted that, because the filter identifier existing in the TFT associated with the video proprietary bearer is the same as the filter identifier existing in the TFT associated with the voice proprietary bearer, that is, the value of the priority of one filter in the TFT associated with the video proprietary bearer is the same as the value of the priority of one filter in the TFT associated with the voice proprietary bearer, the video proprietary bearer is triggered and deactivated according to the protocol, so that the video bearer of the video call is released, and further, the video call has no video picture, so that the video call can fall back to the voice call, and the call quality is not high.

Referring to fig. 3, fig. 3 is a flowchart illustrating a method for modifying a bearer according to an embodiment of the present disclosure. The method for starting the positioning provided by the embodiment of the application can comprise the following steps:

step 301, the UE initiates a video call.

Step 302, the UE and the network device establish a first dedicated bearer.

Step 303, the UE and the network device establish a second dedicated bearer.

The first dedicated bearer may be a voice dedicated bearer, and the second dedicated bearer is a video dedicated bearer. The first proprietary bearer is a video proprietary bearer, and the second proprietary bearer is a voice proprietary bearer. The first dedicated bearer is established before the second dedicated bearer. If the first dedicated bearer is a voice dedicated bearer and the second dedicated bearer is a video dedicated bearer, the establishment procedure is the same as the dedicated bearer establishment procedure in step 105 to step 108 corresponding to fig. 1, and details thereof are not repeated here. If the first dedicated bearer is a video dedicated bearer and the second dedicated bearer is a voice dedicated bearer, the establishment procedure is the same as the dedicated bearer establishment procedure in step 205 to step 208 corresponding to fig. 2, which is not described herein again.

Step 304, the UE initiates a modification request for the first dedicated bearer.

Step 305, the network device sends a message to modify the first proprietary bearer.

Step 306, the ue sends a message to modify the first dedicated bearer.

In particular, the UE detects a filter comprised by the first proprietary bearer and a filter comprised by the second proprietary bearer. If the detection result is that the filter identifier (e.g., the value of the priority) of the first filter included in the TFT in the first proprietary bearer and the second filter identifier included in the TFT in the second proprietary bearer satisfy the conflict condition, the conflict condition may be that the filter identifiers are the same, that is, the value of the priority of the first filter is the same as the value of the priority of the second filter. The filter identification of the first filter and the second filter conflict is recorded.

Further, the UE sends a MODIFICATION REQUEST for the first dedicated BEARER, which may be, for example, a BEARER RESOURCE MODIFICATION REQUEST, and the REQUEST carries the first filter identifier of the first dedicated BEARER. And the network device returns a message for modifying the first dedicated BEARER to the UE through the reconfiguration message, where the message may be, for example, a modified EPS BEARER CONTEXT REQUEST, and the UE performs a deletion process on the first filter and sends a message for completing modifying the first dedicated BEARER, where the message may be, for example, a modified EPS BEARER CONTEXT ACCEPT.

Referring to fig. 4 and fig. 5 together, fig. 4 and fig. 5 are schematic diagrams illustrating a process of establishing a dedicated bearer for a video call according to an embodiment of the present application. Steps 409 to 411 and steps 509 to 511 in fig. 4 and fig. 5 correspond to the above two procedures of establishing the dedicated bearer in different sequences, see steps 304 to 306 in fig. 3, and are not described herein again.

After deletion, it can be seen from the air interface message: the BEARER response MODIFICATION REQUEST initiates a modify flow to delete conflicting filters.
