Problems solved by technology

The VoIP service assigned to the HSDPA channel still needs to use an associated DCH to provide control information. Although the associated DCH has low power, it also consumes system code resources and base station transmission power
If the VoIP service that consumes less power is allocated to the HSDPA channel, it may lead to waste of code resources, decline in spectrum efficiency, and complex scheduling schemes caused by high delays, etc.
[0003] The disadvantage of the prior art is that the channel bandwidth is sufficient, that is, when the channel condition is good, the VoIP service is supported by the dedicated channel, and the power consumption is small, but when the channel condition is not good, the power of the VoIP service supported by the dedicated channel will increase, and the power consumption will increase
When the channel condition is bad, VoIP services are supported by shared channels such as HSDPA channels. Since the total power of the HSDPA channel remains unchanged, the power consumption can be controlled. Channel, due to the service assigned to the HSDPA channel, it is still necessary to use an associated DCH to provide control information. Although the power of the associated DCH is small, it will also increase the consumption of system code resources and the transmission power of the base station; and because the HSDPA channel can be accessed The number of code division users is limited. When using HSDPA channels, if the channels are not used up, it may lead to problems such as waste of code resources and decline in spectrum efficiency.
When a VoIP service applies for access, there is no solution in the prior art that can allocate channels for the VoIP service applying for access according to different needs

Embodiment 1

[0041] Embodiment 1: Using the initial downlink transmission power decision, this embodiment is applicable to UMTS.

[0042] Figure 1 is a schematic diagram of the process of using initial downlink transmit power judgment in channel allocation, and the process shown in Figure 1 includes the following steps:

[0043] Step 101: VoIP service j applies for access.

[0044] There may be many VoIP services to apply for access, and the VoIP service j mentioned in step 101 refers to one of them, which is called VoIP service j in this article.

[0045] Step 102: Estimate the initial downlink transmit power P when the VoIP service j is accessed ini，j .

[0046] In step 102, various methods in the prior art can be used to estimate P ini，j , usually obtain the pilot strength when VoIP service j applies for access, and assume that only DCH can access VoIP service j, and then estimate the P when VoIP service j accesses DCH according to the pilot strength ini，j .

[0047] Step 103: Carr...

Embodiment 2

[0055] Embodiment 2: Using the initial channel quality indication to make a decision, this embodiment is applicable to UMTS.

[0056] Fig. 2 is a schematic diagram of the process of using initial channel quality indication judgment in channel allocation, and the process shown in Fig. 2 includes the following steps:

[0057] Step 201: VoIP service j applies for access.

[0058] Step 202: Estimate the initial channel quality indicator CQI when the VoIP service j is accessed ini，j .

[0059] In step 202, various methods in the prior art can be used to estimate the CQI ini，j , usually obtain the pilot strength when VoIP service j applies for access, and assume that only the HSDPA channel can access VoIP service j, and then estimate the CQI when VoIP service j accesses the HSDPA channel according to the pilot strength ini，j .

[0060] Step 203: Carry out DCH admission control decision and HSDPA channel admission control decision to VoIP service j; if DCH admission control decis...

Embodiment 3

[0068] Embodiment 3: Using initial downlink transmission power or channel quality indication, this embodiment is applicable to UMTS.

[0069] Figure 3 is a schematic diagram of the process of using initial downlink transmission power judgment or channel quality indication judgment in channel allocation, and the process shown in Figure 3 includes the following steps:

[0070] Step 301: VoIP service j applies for access.

[0071] Step 302: Estimate the initial downlink transmission power P when the VoIP service j is accessed ini，j and initial channel quality indicator CQI ini，j .

[0072] In step 302, various methods in the prior art can be used to estimate P ini，j and CQI ini，j , usually obtain the pilot strength when VoIP service j applies for access, and assume that only DCH can access VoIP service j, then estimate the P when VoIP service j accesses DCH according to the pilot strength ini，j , assuming that only the HSDPA channel can access the VoIP service j and then est...

Abstract

The invention discloses a channel distribution method, which includes the following steps: a. It carries out special channel access control decisions and shared channel access control decision for the application of VoIP operation, and executes step b if they allow access VoIP operation at the same time, otherwise accesses the allowing channel or refusing access. b. It compares channel condition parameters and threshold to determine the quality of channel conditions, If the channel conditions are good, VoIP business will be accessed to special channel, otherwise to the sharing channel. The method can distribute channel for the application of VoIP operation reasonably.

Description

technical field [0001] The invention relates to a VoIP service access technology in a mobile communication system, in particular to a channel allocation method in the VoIP service. Background technique [0002] Voice over IP (VoIP, Voice over IP) is a transmission technology for implementing voice communication using a router-based IP packet switching network. One of the evolution trends of the mobile communication system is all-IP network, including service IP. The use of VoIP technology in mobile communication systems can save bandwidth, improve spectrum efficiency, and provide a unified interface and platform for voice and data. If there are dedicated channels and shared channels in the mobile communication system, the VoIP service can be supported by either the dedicated channels or the shared channels. The shared channel means that multiple users occupy the same channel, which may be time division, or code division, or both time division and code division. For exampl...
