Packet Service Functions Tutorial

This section describes how to use the packet data service functions for the packet switched networks.

1. Create an instance of RPhone.
2. Use RPacketService::Open() to create a packet service sub-session to the packet switched network. Use RPacketSercvice::NotifyContextAdded() to get the notification of any new context added to the device
3. 
   Use RPacketService::Attach() to request the telephony server to attach the device to a packet service connection.
4. 
   Use RPacketService::Detach() to request the device to remove from a packet service.
5. 
   Use RPacketService::GetStatus() to retrieve the network status of the packet service. Use RPacketService::NotifyStatusChange() to get the notification of any changes to the packet service network status.
6. 
   Use RPacketService::ContextActicvationRequest() to get the notification of any request to activate a packet service from the network.
7. 
   Use RPacketService::RejectActivationRequest() to reject the network request to activate the packet service.
8. 
   Use RPacketService::EnumerateContexts() to retrieve the number of open contexts and the maximum number of contexts that can be opened.
9. 
   Use RPacketService::CancelAsyncRequest() to cancel an earlier request.
10. 
    Use RPacketService::GetContextInfo() to retrieve the information of a context specified. The function returns the context reference ID and the status of the context.
11. 
    Use RPacketService::NotfyMbmsNetworkServiceStatusChange() to get the notification of any changes to the MBMS.
12. 
    Use RPacketService::GetMbmsNetworkServiceStatus() to retrieve the MBMS support of the network.
13. 
    Use RPacketService::NotifyMbmsServiceAvailabilityChange() to get the notification of any changes to MBMS service availability list.
14. 
    to retrieve the MBMS service available list:
    1. 
       create an instance of CRetrievePcktMbmsMonitoredServices

       CRetrievePcktMbmsMonitoredServices* 
       CRetrievePcktMbmsMonitoredServices::NewL(RPacketService& aService)

    2. 
       start an asynchronous list retrieval

       CRetrievePcktMbmsMonitoredServices::Start(TRequestStatus& aReqStatus);

    3. 
       retrieve the list

       CPcktMbmsMonitoredServiceList*
       CRetrievePcktMbmsMonitoredServices::RetrieveListL() const

    4. 
       Use CRetrievePcktMbmsMonitoredServices::Cancel() to cancel the request to retrieve the list
15. 
    Use RPacketService::UpdateMbmsMonitorServiceListL() to update the MBMS service availability list.
16. 
    Use RPacketService::EnumerateMbmsMonitorServiceList() to retrieve the number of MBMS services monitored and the maximum number of MBMS services supported by the device.
17. 
    Use RPacketService::GetNtwkRegStatus() to retrieve the packet service registration of the device with the network.
18. 
    Use RPacketService::NotifyChangeOfNtwkRegStatus() to get the notification of any changes to the status of the network registration
19. 
    Use RPacketService::GetMSClass() to retrieve the current class and the maximum class of the device. The types of the mobile classes are defined in the TMSClass enumeration.
20. 
    Use RPacketService::SetMSClass() to set the type of class to be used by the device.
21. 
    Use RPacketService::NotifyMSClassChange() to get the notification of any change to the class of the device.
22. 
    Use RPacketService::GetStaticCaps() to retrieve the static capabilities of the device. The static capabilities are defined in the TStaticMiscCaps enumeration.
23. 
    Use RPacketService::GetDynamicCaps() to retrieve the dynamic capabilities of the device. The dynamic capabilities are defined in the TDynamicCaps enumeration.
24. 
    Use RPacketService::NotifyDynamicCapsChange() to get the notification of any changes in the dynamic capabilities of the device.
25. 
    Use RPacketService::SetPreferredBearer() to set the bearer for the class C devices.
26. 
    Use RPacketService::GetPreferredBearer() to retrieve the current bearer for Class C mode.
27. 
    Use RPacketService::SetAttachMode() to instruct the device on how to connect to a packet service. The device can attach to the packet service when available or when required. The types of attach modes are defined in TAttachMode enumeration.
28. 
    Use RPacketService::GetAttachMode() to get the current attach mode defined for the device.
29. 
    Use RPacketService::NotifyAttachModeChange() to get the notification of any changes to the packet service attach mode.
30. 
    Use RPacketService::SetDefaultContextParams() to set the default context parameters.
31. 
    Use RPacketService::GetDefaultContextParams() to get the default context parameters used.
32. 
    Use RTelSubSessionBase::CancelAsyncRequest() to cancel any of the asynchronous commands. Use aReqToCancel parameter to define the command to be cancelled.
33. 
    Use RPacketService::Close() to close a packet service connection
