Problems solved by technology

The RNC does not de-jitter the voice packets, and directly sends the voice packets to the CN. If the jitter of the voice packets received by the CN is too large, the quality of the voice call will be affected.

Embodiment 1

[0028] Firstly, the processing methods for receiving and sending voice packets are respectively described. The solution adopted in this embodiment is: receive voice packets; cache the received voice packets according to the identifier of the received voice packets; The voice packet transmission time interval required by the core network is a period.

[0029] (1) Processing of receiving voice packets:

[0030] In this embodiment, the voice packet of CS over HSPA is described by taking the RNC as a network device for processing the voice packet as an example. During the process of performing uplink (HSUPA) business, voice packets are carried on the E-DCH channel.

[0031] When the RNC receives the first voice packet P1, it puts P1 into the cache and starts a cache timer timer1 at the same time. When timer1 expires, the RNC sends P1 to the CN, and at the same time starts the sending timer, and the timing period of the sending timer is 20ms. After each voice packet is sent, th...

Embodiment 2

[0064] In the above embodiment, each time the RNC puts a voice packet into the buffer, it can start a buffer timer. Its function is to avoid the voice delay caused by the abnormal jitter of a certain voice packet and the following voice packets staying in the cache for too long. However, in practical applications, if a cache timer is maintained for each voice packet, a large amount of system resources may be occupied, and it is difficult to implement for a system with poor processing capability or less memory. In view of this, in this embodiment, after the voice packet is put into the cache, the cache timer may not be started, and the sending of the voice packet is controlled by the sending timer.

[0065] (1) Processing of receiving voice packets:

[0066] When the RNC receives the first voice packet P1, it does not put it into the cache, but directly sends it to the CN, starts the sending timer at the same time, and records the identification value of the next voice packet ...

Embodiment 3

[0084] Corresponding to the above method embodiment, the embodiment of the present invention also provides a voice packet sending device, see Figure 5 As shown, it includes: a receiving unit 510, a buffer unit 520 and a sending unit 530;

[0085] A receiving unit 510, configured to receive voice packets;

[0086] The buffering unit 520 is used for buffering the received voice packet according to the identifier of the received voice packet;

[0087]The sending unit 530 is configured to send the voice packets in the cache to the core network when the sending time is reached, and the sending time is based on the voice packet transmission time interval required by the core network.

[0088] Wherein, the sending unit 530 may include a first determining subunit 531 and a first sending subunit 532, see Figure 6 shown.

[0089] The first determining subunit 531 is used to determine the next voice packet of the voice packet that should be sent last time as the voice packet that sh...

Abstract

An embodiment of the invention discloses a method, a device and a system for transmitting sound package. The method for transmitting the sound package comprises the following procedures: receiving the sound package; caching the received sound package according to the identification of the received sound package; and transmitting the sound package in the cache to a core network a transmitting time which uses a sound package transmitting time period requested by the core network as a period is arrived. The technical scheme of embodiment of the invention can be applied to ascending service of CS over HSPA. Interference eliminating to the ascending sound package is realized through caching the sound package to guarantee that the sound package is transmitted to the core network through a fixed time interval requested by the core network thereby guaranteeing the continuity of sound and increasing the communication quality of sound.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method, device and system for sending voice packets. Background technique [0002] With the continuous development of communication technology, in order to meet the new requirements of network performance brought by the growing wireless data services, HSPA (High Speed Packet Access, high-speed packet access) technology, its uplink and downlink access technologies are called HSUPA (High Speed ​​Uplink Packet Access, high-speed uplink packet access) and HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink packet access). In HSUPA, the most notable feature is the addition of a new uplink transmission channel type E-DCH (Enhanced-Dedicated Channel, enhanced dedicated channel), each UE (User Equipment, user equipment) uses a dedicated E-DCH transmission channel, and The DCH or E-DCH used by other UEs are independent of each other, which improves the transmission ra...
