Introduction

The HSUPA functionality is supported +by extending the multimode +telephony API and the packet +data telephony API. HSUPA is defined in 3GPP R6 specifications.

HSUPA +provides users with a high speed uplink, which allows network operators to +provide more interactive value-added data services. HSUPA improves data throughput +and reduces delays by using technologies such as adaptive modulation and hybrid +ARQ. The main advantages of using HSUPA is that it does not require any hardware +modifications to existing network and phones that already supports 3G.

Developers +who wish to use HSUPA functionality should include etelmm.dll and etelpckt.dll in +their MMP files.

HSUPA support by the phone

The following steps +enables the client applications to find out if the phone supports HSUPA or +not:

    +

  1. Create an instance of RMobilePhone

    2. +

  2. Open a new RPacketService

    3. +

  3. Call RPacketService::GetStaticCaps() to +find out if HSUPA is supported by the phone

    4. +

  4. The function returns +with information regarding the support for 3G network service, HSUPA and HSDPA

    5. +

HSUPA support by the network

Home network support

Clients +can verify if the home network supports HSUPA by calling RMobilePhone::GetHomeNetwork(). +The function returns the network support details in a TMobilePhoneNetworkInfoV8 object.

Current +network support

Clients can verify if the current network supports +HSUPA by calling RMobilePhone::GetCurrentNetwork(). The +network support details are returned in a TMobilePhoneNetworkInfoV8 object. +Clients can be notified of the changes to the current network by RMobilePhone::NotifyCurrentNetworkChange(). +The change details are returned in a TMobilePhoneNetworkInfoV8 object.

HSUPA +support by detected networks

Clients can verify if HSUPA is supported +by other detected networks by calling CRetrieveMobilePhoneDetectedNetworks::StartV8(). +This is a two-phase retrieval process. After calling the CRetrieveMobilePhoneDetectedNetworks::StartV8(), +clients should call CMobilePhoneNetworkListV8 * CRetrieveMobilePhoneDetectedNetworks::RetrieveListV8L(). +The network capabilities are returned in a TMobilePhoneNetworkInfo object.

Querying +the HSUPA connection state

When clients have verified HSUPA support +by the phone, they can query the state of a HSUPA connection by calling RPacketService::GetDynamicCaps().
