Service processing method and apparatus

An access network device, comprising:

• a transceiver, configured to receive a connection setup message sent by user equipment (UE), wherein the connection setup message comprises first voice session indication information that indicates that the connection setup message is sent due to a Voice over Long Term Evolution (VoLTE) voice session;
• and configured to receive a resource scheduling request message sent by the UE;
• and
• a processor, configured to allocate an uplink transmission resource to the UE if the transceiver receives the resource scheduling request message sent by the UE within a first time period that is associated with a setup duration of a VOLTE voice session after the connection setup message is received.

User equipment (UE), comprising:

• a transceiver, configured to send a connection setup message to an access network device, wherein the connection setup message comprises first voice session indication information that indicates that the connection setup message is sent due to a Voice over Long Term Evolution (VoLTE) voice session;
• wherein
• the transceiver is configured to:
• send a resource scheduling request message to the access network device, and transmit an uplink data packet according to an uplink transmission resource allocated by the access network device, wherein the uplink transmission resource is allocated by the access network device to the UE when the resource scheduling request message is received by the access network device within a first time period that is associated with a setup duration of a VoLTE voice session after the access network device receives the connection setup message sent by the UE.
