Method and apparatus for ensuring voice business quality in terminal concurrence business

Abstract

The invention provides a device which protects voice over internet protocol in terminal concurrent service, which comprises a first processing entity which is used to execute shifting function for MAC-hs PDU to get MAC-d protocol data unit MAC-d PDU, and execute shifting to the MAC-d PDU when the MAC-d PDU is provided with C / T field, a second processing entity which is used to receive and transmit the processing results of the first processing entity, and process DCH service, when the process of processing shifting of the first processing entity conflicts with the process of process DCH of the second processing entity, the DCH service is firstly processed. The invention firstly process voice over internet protocol through repeatedly diving MAC layer protocol of the UE side into an MACHS entity and MACD entity when HSDPA service and voice over internet protocol are concurrent, thereby guaranteeing conversion quality.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for ensuring the quality of voice services in a high-speed downlink packet access (High Speed ​​Downlink Packet Access, HSDPA) system and terminal user equipment when HSDPA services and voice services are concurrent. Background technique [0002] HSDPA technology is a downlink enhancement technology proposed by the third-generation mobile communication partnership organization 3GPP in its Release 5 specification. This technology greatly improves the downlink data transmission rate and radio resource utilization efficiency of the third-generation wireless system, and significantly reduces the data The transmission delay is very beneficial for supporting data services such as video, streaming media, and downloading that require high traffic and delay. [0003] In order to achieve the purpose of increasing downlink packet data rate and reducing time delay, HSD...

Problems solved by technology

[0011] In fact, due to limitations in size, power consumption, cost, etc., the processing capabilities of terminals are usually limited. When traditional voice services and HSDPA services are concurrent, the MAC-d entity and the MAC-hs entity are located In the same task, the MAC-d entity may need to process HSDPA services and voice services at the same time, and the above shift operation may occupy a large amount of CPU processing time, so that the terminal has no time to process the DCH transmission channel carrying voice services, and misses the transmission of the air interface At any time, it is impossible to ensure that data is sent and received evenly according to the 20 millisecond cycle required by the voice service, which will eventually lead to a decline in the quality of the voice call and affect the use of users.
