Problems solved by technology
The field test found that the uplink data packet burst and packet discarding are important factors for voice quality degradation during the handover process. Timely dispatch uplink resources to terminals
The main manifestations are: before the discard timer expires, if the scheduling is successful, the uplink data burst will be caused, which will increase the jitter and affect the voice quality; Increased packet loss rate on the receiving side, affecting voice quality

The invention discloses a terminal resource allocation method, an eNB (evolved NodeB) and a VoLTE (Voice over Long Term Evolution) system and relates to the field of communication. The method comprises the steps that a target eNB judges whether handover business is VoLTE business or not; and if the handover business is the VoLTE business, after the target eNB determines that radio resource control(RRC) connection is established with a calling terminal of the VoLTE business, the target eNB allocates a resource for reporting a buffer status report (BSR) to the calling terminal without waiting for a scheduling request (SR) sent by the calling terminal. According to the allocation method, the eNB and the VoLTE system provided by the invention, the influence of the SR undetected problem on thevoice quality of the VoLTE business in a handover process can be solved, so an uplink data packet of the VoLTE business after the handover can be sent real time, the VoLTE business quality is improved, and the user experience is improved.
Description
technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for allocating terminal resources during service switching, an eNB and a VoLTE system. Background technique [0002] The VoLTE (Voice over Long Term Evolution, voice service carried on the LTE network) service is the voice service carried on the LTE (Long Term Evolution, long-term evolution technology) network, and is the direction of voice service evolution. It is expected that operators' voice services will migrate from 2G / 3G networks to LTE networks in the future. The user experience of VoLTE services will be an important basis for operators to compete, and the voice quality of VoLTE services is the most important indicator that operators pay attention to. [0003] In an actual network, voice quality degradation during user switching is an important reason for affecting the voice quality of VoLTE services. According to the field test, the uplink ...
