Problems solved by technology

[0002] In order to ensure the continuity of the voice service, in the LTE system, if the evolved Node B (eNB, evolved Node B) initiates a context release request (UE CONTEXT RELEASE REQUEST) to the Mobility Management Entity (MME, Mobility Management Entity), the MME Generally, the guaranteed bit rate (GBR, Guranteed Bit Rate) bearer is not reserved, which will cause the user equipment (UE, User Equipment) to fail to quickly restore the voice bearer after re-connecting to the LTE or other systems, which will easily cause the UE to drop the call. Affecting users' voice service experience

Embodiment 1

[0031] figure 2 It is a flowchart of the first embodiment of the present invention, and this embodiment is mainly used to illustrate a specific method for reducing the VoLTE call drop rate when the coverage-based Intra-RAT Redirection is used. Such as figure 2 As shown, the method for reducing the dropped call rate in the first embodiment of the present invention includes:

[0032] Step 201: UE initiates VoLTE service;

[0033] Step 202: The MME and the eNB accept the VoLTE service, and the voice call is established;

[0034] Step 203: The eNB judges that the signal quality of the current serving cell of the UE is poor, and the signal quality of other frequency points in the LTE system is good, and then initiates Intra-RAT Redirection to instruct the UE to re-access the frequency point with good signal quality;

[0035] Step 204: the eNB sends a UE context release request message to the MME, and the message carries a specific identifier;

[0036] Step 205: The MME receives the UE con...

Abstract

The present invention relates to a method, device and system for reducing a call drop rate in the field of the audio business field in the long-term evolution system. The method comprises: receiving a UE context releasing request sent or ERAB releasing indication information by an eUB, when the UE context releasing request sent or ERAB releasing indication information carries special identification, remaining the BGR bearing, and the special identification is used for indicating to remain the GBR bearing. Correspondingly, the present invention further discloses a method, device and system for reducing a call drop rate. The method, device and system for reducing the call drop rate can effectively reduce the call drop rate of the UE in the VoLTE business and improve the user experience.

Description

Technical field [0001] The present invention relates to the field of mobile communication systems, in particular to a method, device and system for reducing the drop rate of user equipment (UE, User Equipment) in the voice service (VoLTE, Voice over LTE) field in the Long Term Evolution (LTE) system . Background technique [0002] In order to ensure the continuity of voice services, in the LTE system, if an evolved Node B (eNB, evolved Node B) initiates a context release request (UE CONTEXT RELEASE REQUEST) to a mobility management entity (MME, Mobility Management Entity), the MME Generally, the Guranted Bit Rate (GBR) bearer is not reserved. This will cause the user equipment (UE, User Equipment) to reconnect in LTE or other systems, and the voice bearer cannot be quickly restored, which may easily cause the UE to drop calls. Affect the user's voice service experience. Summary of the invention [0003] The present invention makes improvements to the above-mentioned problems in ...
