A method, base station and terminal for high-definition voice calls

Abstract

An embodiment of the present invention provides a method for high-definition voice calls, a base station, and a terminal. The method is applied between the base station and the terminal; the method includes: when the base station receives a high-definition voice data radio bearer establishment request, The base station allocates an air interface data radio bearer ID for the high-definition voice data radio bearer; judges whether the next air interface data radio bearer ID of the air interface data radio bearer ID is reversed; if not, based on the air interface data radio bearer ID Establishing a high-definition voice data wireless bearer between the base station and the terminal; the base station performs a high-definition voice call with the terminal through the high-definition voice data wireless bearer. The embodiment of the present invention adopts a set of brand-new air interface drbid allocation algorithm, which not only meets the air interface data security requirements of the LTE protocol, but also ensures the data security of the user's VoLTE call.

Description

technical field [0001] The present invention relates to the technical field of communication technology, in particular to a method for high-definition voice communication, a base station and a terminal. Background technique [0002] High-definition voice calls, also known as VoLTE calls, are a voice technology. VoLTE is the abbreviation of Voice OverLTE in English. The literal translation is that audio is transmitted through the LTE network. VoLTE is a voice service based on IMS (IP Multimedia Subsystem, IP Multimedia Subsystem). IMS has become the core network standard architecture in the all-IP era because it supports multiple access and rich multimedia services. After the development and maturity of the past few years, IMS has now crossed the rift and become the mainstream choice for VoBB (Voice Over Broadband, broadband voice) and PSTN (Public Switched Telephone Network, public switched telephone network) network reform in the fixed voice field. Determined by 3GPP and ...

Problems solved by technology

[0004] However, in the existing technology, the intra-cell handover and VoLTE bearer are established in one air interface reconfiguration message to send. Some commercial terminals that support VoLTE in the market do not support this air interface signaling, which will lead to air interface reconfiguration failure, and then lead to VoLTE call failure. affect user experience

[0005] Some manufacturers use fixed VoLTE bearer allocation drbid to solve the above problems, which will not trigger the handover process in the cell and ensure the successful establishment of VoLTE bearer. However, this mechanism does not meet the air interface data security requirements of the LTE protocol, and there will be hidden dangers in data security.
