Abstract

The embodiment of the invention provides a bearer establishment request method and device, electronic equipment and a storage medium. The method comprises the steps that a VoLTE SBC / P-CSCF obtains a policy control function PCF address; and based on the PCF address, sending an access authorization request AAR message to the PCF, and requesting to establish a voice dedicated bearer. According to the embodiment of the invention, the PCF address is acquired in advance, the access authorization request AAR message is directly sent to the PCF based on the PCF address, and the establishment of the voice dedicated bearer is requested, so that a complex signaling process of acquiring the PCF address through a DRA in the prior art is avoided, signaling in the bearer establishment request process is saved, and the connection delay of the VORR voice service is reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a bearer establishment request method, apparatus, electronic device and storage medium. Background technique [0002] After the VoLTE SBC / P-CSCF initiates the VoNR basic voice service process, it needs to start the dynamic PCC process and send the AA-R message to the PCF device to request the establishment of a dedicated voice bearer. [0003] In the prior art, the session binding information between the user IP address and the PCF address is stored in the BSF. When the VoLTE SBC / P-CSCF sends an AAR message to the PCF through the Rx interface to request the establishment of a dedicated voice bearer, it needs to query the local session binding through the DRA. The data obtains the PCF address. If it cannot be queried, it needs to perform BSF service discovery and other signaling processes to the NRF. The signaling process is relatively complex, which affects...
