The voice session indication information may be further used to indicate that the access network device receives the first downlink data packet that includes the voice session indication information, and sends the The resource scheduling request message, the access network device preferentially allocates an uplink transmission resource to the UE.

The voice session indication information may be generated by the IMS network device or generated by other network element devices. For example, it can be generated for any of the following network element devices:

Core network control equipment; core network gateway equipment.

For example, the voice session indication information is generated by the IMS network device in the data packet encapsulating the downlink SIP signaling after determining that the VoLTE voice session downlink SIP signaling is received. The IMS network device encapsulates the VoLTE voice session downlink SIP signaling data packet is generally an IP data packet, and the IMS network device encapsulates the IP address of the called UE according to the IP address indicated by the called UE when the IMS is registered. The header of the IP data packet is in the header.

For example, voice session indication information may be generated for a core network gateway device. When the core network gateway device is the P-GW, the P-GW receives the downlink data packet that is sent by the IMS network device, including the voice session indication information generated by the IMS network device, and generates the voice session indication information to replace the voice generated by the IMS network device. Session indication information. Of course, the P-GW may not generate the voice session indication information, but directly use the voice session indication information generated by the IMS network device as the voice session indication information, and encapsulate the information in the downlink data packet, and transmit the message to the next hop node, such as the SGW. .

For example, when the core network gateway device is the SGW, the SGW receives the downlink data packet that is sent by the P-GW and includes the voice session indication information generated by the P-GW, and generates the voice session indication information to replace the voice generated by the P-GW. Session indication information. Of course, the SGW may not generate the voice session indication information, but directly use the voice session indication information generated by the P-GW as the voice session indication information, and encapsulate the downlink data packet and send it to the next hop node, such as the core network control device. .

For example, the voice session indication information may be generated by the core network control device, and the core network control device generates a voice session after receiving the downlink data packet that is sent by the core network gateway device and includes the voice session indication information generated by the core network gateway device. The indication information replaces the voice session indication information generated by the core network gateway device. As a matter of course, the core network control device may not generate the voice session indication information, but directly use the voice session indication information generated by the core network gateway device as the voice session indication information, and encapsulate the downlink data packet and send it to the next hop node, such as The access network device.

In the first downlink data packet that is received by the access network device, including the voice session indication information, the voice session indication information may be located in any one of the following fields in the header of the first downlink data packet:

Specific Differentiated Services Code Point (DSCP); Terms of Service (TOS); Traffic Class; Flow Label; Field of the General Packet Radio Service (GPRS) tunneling protocol carrying the downlink data message. The voice session indication information may be a pre-agreed specific code. After determining that the first downlink data packet includes the specific code, the access network device may determine that the first downlink data packet is data that carries the voice session indication information. Message.

For example, the IMS network device is a P-CSCF, and the voice session indication information generated by the P-CSCF may be located in a DSCP field in a header of a downlink IP data packet. For example, the P-CSCF may set the DSCP to a pre-agreed value. After receiving the IP data packet, the network element device, such as the access network device, can determine that the IP data packet encapsulates the downlink SIP signaling of the VoLTE voice session according to the DSCP in the header of the IP data packet.

The data packet encapsulating the downlink SIP signaling of the VoLTE voice session is generally transmitted on the VoLTE voice signaling plane bearer. In order to reduce the workload of the access network device, the access network device needs to determine the voice session indication information before determining whether the received first downlink data packet sent to the UE includes the voice session indication information. The first downlink data packet is transmitted on a VoLTE voice signaling plane bearer, and the VoLTE voice signaling plane bearer refers to a bearer that can be used to transmit VoLTE voice session signaling. Of course, in addition to the VoLTE voice session signaling, the bearer may also be used for the transmission of other types of data, which is not limited herein. Specifically, after receiving the first downlink data packet sent to the UE, the access network device determines whether the first downlink data packet is transmitted on a VoLTE voice signaling plane bearer. If yes, determining whether the voice session indication information is included in the first downlink data packet. If the access network device determines that the received first downlink data packet is not transmitted on the bearer of the VoLTE voice session signaling, it does not determine whether the voice session indication information is included in the first downlink data packet.

Further, the value of the QCI carried by the VoLTE voice signaling plane is usually 5, and therefore, after receiving the first downlink data packet sent to the UE, the access network device determines to send to the Whether the first downlink data packet of the UE is transmitted on the bearer with the value of the QCI is 5, and if yes, whether the voice session indication information is included in the first downlink data packet. If the access network device determines that the received first downlink data packet is not transmitted on the bearer with the QCI value of 5, Determining whether the voice session indication information is included in the first downlink data packet.

Optionally, after determining that the first downlink data packet carries the voice session indication information, the access network device is configured to enable the access network device to process data related to VoLTE voice session signaling in time. The packet is transmitted to ensure the establishment of the VoLTE voice session, and the access network device may need to preferentially allocate the downlink transmission resource according to the first downlink data packet sent to the UE, and send the first downlink by using the downlink transmission resource. A row data message is sent to the UE.

S202. The access network device preferentially obtains a resource scheduling request message sent by the UE in a first time period after receiving the first downlink data packet. The UE allocates uplink transmission resources.

Specifically, after receiving the first downlink data packet, the access network device may start a first timer, where a timing duration of the first timer is the first time period; The network access device preferentially allocates an uplink transmission resource to the UE if the resource scheduling request message sent by the UE is received before the first timer expires. After the access network device determines that the first timer expires, even if the resource scheduling request message sent by the UE is received, the uplink transmission resource may not be preferentially allocated to the UE.

The resource scheduling request message sent by the UE that is received by the access network device may be a Scheduling Request (SR) or a Buffer Status Reports (BSR).

When the uplink data needs to be transmitted, the UE needs to first send an SR to the access network device, and request the access network device to allocate an uplink transmission resource for transmitting the uplink data packet. Optionally, the UE further needs to send a BSR to the access network device, to inform the access network device of the data volume of the uplink data packet to be transmitted, so that the access network device can be configured according to the data of the uplink data packet to be transmitted. The amount is used by the UE to schedule uplink transmission resources. Therefore, the SR or BSR received by the access network device is sent by the UE to the access network device before the uplink data needs to be transmitted.

For example, after receiving the first downlink data packet including the voice session indication information, the access network device may start a first timer, where the first timer has a timing duration of the first timer. a period of time; the access network device receives the sending of the UE before the first timer expires The SR or the BSR, the access network device preferentially allocates an uplink transmission resource to the UE according to the SR or the BSR sent by the UE. After the access network device determines that the first timer expires, even if the resource scheduling request message sent by the UE is received, the uplink transmission resource may not be preferentially allocated to the UE.

It should be noted that the first time period may be adjusted according to actual conditions. The access network device can set different first time periods for different downlink data packets.

For example, if the access network device receives the first downlink data packet sent to the user equipment UE, the second downlink data packet sent to the UE, the second downlink data packet is further received. The voice session indication information is included, and the access network device receives the resource scheduling request message sent by the UE, in the second time period after receiving the second downlink data packet, The access network device preferentially allocates uplink transmission resources to the UE.

Optionally, the second downlink data packet is an IP data packet.

Similarly, in the second downlink data packet that is received by the access network device, including the voice session indication information, the voice session indication information may be located in any one of the following fields in the packet header of the second downlink data packet. :

A specific differentiated service code point; a clause of service; a type of traffic; a flow label; a field of a general packet radio service tunneling protocol carrying the downlink data message.

The access network device may also use a timer to allocate an uplink transmission to the UE according to the received resource scheduling request message sent by the UE in a second time period after receiving the second downlink data packet. Resources. Specifically, after receiving the second downlink data packet, the access network device starts a second timer, where a timing duration of the second timer is the second time period; the access network The device, when receiving the resource scheduling request message sent by the UE, before the second timer expires, the access network device preferentially allocates an uplink transmission resource to the UE. After the access network device determines that the second timer expires, even if the resource scheduling request message sent by the UE is received, the uplink transmission resource may not be preferentially allocated to the UE. It should be noted that the duration of the first period of time and the duration of the second period of time may be equal; the duration of the first period of time and the duration of the second period of time may also be unequal. Optionally, the first timer and the second timer may be The same entity can also be a different entity.

In an implementation manner of the embodiment of the present invention, if the first timer corresponding to the first downlink data packet has expired and stops running, the access network device starts after receiving the second downlink data packet. The second timer, the duration of the second timer may be different from the duration of the first timer; if the first timer corresponding to the first downlink data packet is not timed out, the access network device is receiving the After the second downlink data packet, the first timer is stopped, and the second timer is started. The second timer may be different from the first timer.

It is to be noted that, in another implementation manner of the embodiment of the present invention, after the access network device starts the first timer, even if the second session that includes the voice session indication information is sent to the UE The second downlink data packet does not start the second timer, but allows the first timer to continue counting until the first timer expires. At this time, preferably, the first time period may be set to a maximum/average statistical duration required for establishing a VoLTE voice session, so that the uplink data message sent by the UE may be preferentially scheduled during the establishment of the VoLTE voice session.

Similarly, after receiving the second downlink data packet, the access network device may further allocate a downlink transmission resource, and send the second downlink data packet to the UE by using the downlink transmission resource. .

Optionally, before determining, by the access network device, whether the received second session data message sent to the UE includes the voice session indication information, the access network device may further determine that the second downlink data packet is The VoLTE voice signaling plane bearer carries the bearer, and the VoLTE voice signaling plane bearer refers to a bearer that can be used for transmitting VoLTE voice session signaling. Specifically, after receiving the second downlink data packet sent to the UE, the access network device determines whether the second downlink data packet is transmitted on a VoLTE voice signaling plane bearer, if And determining whether the voice session indication information is included in the second downlink data packet. If the access network device determines that the received second downlink data packet is not transmitted on the bearer of the VoLTE voice session signaling, it does not determine whether the second downlink data packet includes the voice session indication information.

Further, after receiving the second downlink data packet sent to the UE, the access network device determines whether the second downlink data packet sent to the UE is a bearer with a value of 5 on the QCI. Transmission If yes, determine whether the voice session indication information is included in the second downlink data packet. If the access network device determines that the received second downlink data packet is not transmitted on the bearer with the value of the QCI, it does not determine whether the second downlink data packet includes the voice session indication information.

Similarly, the process in which the called UE establishes the VoLTE voice media plane bearer may also be as shown in the above process, and details are not described herein again.

Based on the above description, please refer to FIG. 6. FIG. 6 is a schematic flowchart diagram of another service processing method according to an embodiment of the present invention.

As shown in FIG. 6 , another service processing method provided by the embodiment of the present invention may include:

S601. The access network device receives a bearer setup request message sent by the core network device, where the bearer setup request message is used to request to establish a VoLTE voice media plane bearer for the user equipment UE, where the VoLTE voice media plane bearer is used to transmit VoLTE. Bearer of voice service media data.

Optionally, the value of the QCI carried by the VoLTE voice media plane is 1.

The access network device may be an access network device corresponding to the calling UE or an access network device corresponding to the called UE.

S602. The access network device preferentially allocates the resource scheduling request message sent by the UE to the UE in a third time period after receiving the bearer setup request message. Uplink transmission resources.

Specifically, after receiving the connection establishment request message, the access network device starts a third timer, where a timing duration of the third timer is the third time period; If the resource scheduling request message sent by the UE is received before the third timer expires, the access network The device preferentially allocates uplink transmission resources to the UE. After the access network device determines that the third timer expires, even if the resource scheduling request message sent by the UE is received, the uplink transmission resource may not be preferentially allocated to the UE.

The resource scheduling request message sent by the UE that is received by the access network device may be an SR, or may be a BSR.

For example, after receiving the bearer setup request message, the access network device may start a third timer, where the timing duration of the third timer is the third time period; Before receiving the SR or the BSR sent by the UE, the access network device preferentially allocates an uplink transmission resource to the UE according to the SR or the BSR sent by the UE. After determining that the third timer expires, the access network device may not allocate uplink transmission resources to the UE according to the SR or BSR sent by the UE.

Optionally, the access network device may also receive a downlink data packet sent to the UE, where the access network device may receive the data packet related to the VoLTE voice session signaling. And the fourth time period after the bearer setup request message is sent, if the access network device receives the downlink data packet sent to the UE, the downlink transmission resource is preferentially allocated, and is sent by using the downlink transmission resource. The downlink data packet is sent to the UE. Specifically, after receiving the connection establishment request message, the access network device starts a fourth timer, where a timing duration of the fourth timer is the fourth time period; Before the fourth timer expires, if the access network device receives the downlink data packet sent to the UE, the downlink transmission resource is preferentially allocated, and the downlink data packet is sent according to the downlink transmission resource. Sent to the UE. After the access network device determines that the fourth timer expires, even if the resource scheduling request message sent by the UE is received, the access network device does not need to be prioritized. Allocating uplink transmission resources to the UE.

It should be noted that the third time period and the fourth time period may be set according to actual conditions.

The third timer and the fourth timer may be the same entity or different entities, and the timing duration of the third timer and the timing duration of the fourth timer may be the same or different.

Optionally, the third time period may be set to a maximum/average statistical duration required for establishing a VoLTE voice session, so as to ensure that uplink data packets sent by the UE are preferentially scheduled during the establishment of the VoLTE voice session. The fourth time period may be set to the maximum/average statistical duration required for establishing a VoLTE voice session, so that the downlink data message sent to the UE is preferentially scheduled during the establishment of the VoLTE voice session. Of course, the third time period or the fourth time period may also be adjusted according to actual conditions.

The data packets related to the VoLTE voice session signaling are generally transmitted on the VoLTE voice signaling plane bearer. In order to reduce the workload of the access network device, before the access network device preferentially allocates the downlink transmission resource, the downlink data packet sent to the UE may be transmitted on the VoLTE voice signaling plane bearer. The VoLTE voice signaling plane bearer refers to a bearer that can be used to transmit VoLTE voice service signaling. Of course, in addition to VoLTE voice session signaling, the bearer may also be used for other types of data transmission. limited. Specifically, after receiving the downlink data packet sent to the UE, the access network device determines whether the downlink data packet is transmitted on a VoLTE voice signaling plane bearer, and if so, according to the The downlink data packet preferentially allocates downlink transmission resources. If the access network device determines that the received downlink data packet sent to the UE is not transmitted on the bearer of the VoLTE voice session signaling, the downlink transmission resource may not be preferentially allocated.

Further, the value of the QCI carried by the VoLTE voice signaling plane is usually 5. Therefore, after receiving the downlink data packet sent to the UE, the access network device determines the downlink sent to the UE. Whether the data packet is transmitted on the bearer with a value of 5 on the QCI, and if yes, the downlink transmission resource is preferentially allocated according to the downlink data packet. If the access network device determines that the received downlink data packet sent to the UE is not transmitted on the bearer with the value of the QCI, the downlink transmission resource may not be preferentially allocated.

In the foregoing solution, after determining, according to the bearer setup request message, the access network device needs to establish a VoLTE voice media plane bearer for the user equipment UE, the resource scheduling request message sent by the UE may be preferentially scheduled and/or the priority dispatched to the office The downlink data packet of the UE is described, thereby improving the processing efficiency of processing and VoLTE voice session signaling, and ensuring the establishment of a VoLTE voice session.
