[0051] Such as figure 1 As shown, the first embodiment of the present invention provides a packet loss judgment method, including:

[0052] Step 11, determining the service type of at least one service data packet contained in the physical layer data packet sent by the data sending end;

[0053] Step 12: Carry out cyclic redundancy checks on service data packets of different service types respectively, and determine whether to discard the service data packets.

[0054] In the above embodiments of the present invention, a physical layer data packet may contain a service data packet of one service type, or may contain multiple service types of service data packets, which is not specifically limited here. The receiving end judges the service type to be performed by the data sending end according to preset rules (that is, the service type of the service data packet included in the physical layer data packet).

[0055] After distinguishing the service types of different service d...

[0085] Such as figure 2 As shown, the second embodiment of the present invention also provides a packet loss judgment device, including:

[0086] A type determining module 21, configured to determine the service type of at least one service data packet included in the physical layer data packet sent by the data sending end;

[0087] The packet loss determination module 22 is configured to perform cyclic redundancy checks on the service data packets of different service types, and determine whether to discard the service data packets.

[0088] Specifically, the device described in the second embodiment of the present invention also includes:

[0089] The identification module is configured to configure different scheduling resources for service data packets of different service types, and to configure different identifications for service data packets of different service types.

[0090] Specifically, the identification module described in the second embodiment of the presen...

Abstract

The invention provides a packet loss judgment method and device. The method includes the following steps: determining the service type of at least one service data packet included in a physical layerdata packet sent by a data transmitting end; and performing cyclic redundancy check on the service data packets with different service types respectively, and determining whether to discard the service data packets. According to the embodiment of the invention, a receiving end identifies the service type of the physical layer data packet, and thus the process of performing cyclic redundancy checkon the service data packets with different service types and determining whether to discard the service data packets with the service type is performed; and by adopting the packet loss judgment method, only discarding the service data packets with a certain service type in a packet loss process is allowable, and thus the integrity and flexibility of service data can be improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a packet loss judgment method and device. Background technique [0002] In the existing LTE network, the physical layer data packet of the same user may be a collection of many services (such as a mix of voice and data services), and the receiving end is generally unable to distinguish the type of service to which the data packet belongs; the physical layer at the receiving end After the layer fails to perform a cyclic redundancy check (Cyclic Redundancy Check, CRC) on the data packet, the data packet will be discarded, so all various service data contained in the data packet will be discarded. [0003] When the user is making a VoLTE voice call, the word swallowing phenomenon will occur when processing according to the above processing method, that is, the cause of the word swallowing phenomenon is that the voice packets are continuously discarded.
