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.

Embodiment Construction
[0049] In the present invention, the MAC-hs, MAC-d and MAC-c / sh entities of the MAC layer on the UE side are re-divided into the first processing entity, which is defined as the MADHS entity and the second processing entity, which is defined as the MACD entity. The function of removing the MAC-d header with MAC-d is implemented in the MACHS entity, and the MADHS entity and the MACD entity are respectively defined as lower and higher processing priorities. In this way, when the HSDPA service and the voice service are concurrent, the voice service can be guaranteed to be processed first, thereby ensuring the call quality.
[0050] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0051] Such as Figure 5 as shown, Figure 5 It is a schematic diagram of UE MAC layer structure in the present invention. The present invention adopts a priority-based preemptive embedded operating ...

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 transmitthe 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 thesecond 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 present invention relates to the field of mobile communication, in particular to a method and a device for ensuring voice service quality when HSDPA service and voice service are concurrent in a high speed downlink packet access (High Speed Downlink Packet Access, HSDPA) system and terminal user equipment. Background technique [0002] HSDPA technology is a downlink enhancement technology proposed by the third-generation mobile communication partner organization 3GPP in its Release 5 specification. This technology greatly improves the downlink data transmission rate and wireless resource utilization efficiency of the third-generation wireless system, and significantly reduces data transmission. Transmission delay is very beneficial for supporting data services such as video, streaming media, and downloads that require high traffic and delay. [0003] In order to increase the downlink packet data rate and reduce the time delay, HSDPA introduces ke...
