High-definition voice call method, base station and terminal

Abstract

The embodiment of the invention provides a high-definition voice communication method, a base station and a terminal. The method is applied between the base station and the terminal. The method comprises the following steps: when the base station receives a high-definition voice data radio bearer establishment request, the base station distributes an air interface data radio bearer ID for the high-definition voice data radio bearer; judging whether the next air interface data radio bearer ID of the air interface data radio bearer ID is overturned or not; if not, establishing a high-definitionvoice data radio bearer of the base station and the terminal based on the air interface data radio bearer ID; and enabling the base station to carry out high-definition voice communication with the terminal through the high-definition voice data radio bearer. According to the embodiment of the invention, a brand-new air interface distribution algorithm is adopted, so that the requirement on the air interface data security of the LTE protocol is met, and the data security of a VoLTE call of a user is ensured.

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.
