<concept id="GUID-6BE03135-6192-5520-AE8F-80BDB3187259" xml:lang="en"><title>User

Prompt Service</title><shortdesc>According to the platform security model of Symbian platform, any

application connecting to a network must have the <codeph>NetworkServices</codeph> capability.

All applications that have the <codeph>Networking service</codeph> capability

must be signed. The Comms User Prompt Service (UPS) enables even the unsigned

applications to access the network if user authorisation is provided. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>Any application that requires network access uses the <xref href="GUID-61E0CD76-A2E3-5066-84A8-146EECA8ADCD.dita">Socket

Server</xref> API with the help of <xref href="GUID-BED8A733-2ED7-31AD-A911-C1F4707C67FD.dita"><apiname>RConnection</apiname></xref> or <xref href="GUID-D4F08503-F1EF-3531-9C3C-4AF24A6255F0.dita"><apiname>RSocket</apiname></xref>.

The platform security model checks the capability of the client application

to access the network. The comms user prompt service is used to notify the

user about the network access. The UPS feature enables applications without <codeph>NetworkServices</codeph> capability

to access the network if the user authorises the connection. </p>

<p>The target audience of this document is the device creators who write MCPR

plug-ins. Symbian provides a reference plug-in for the device creators, which

can be modified for customisation. The device creators implementing the comms

user prompt service must have knowledge of the Comms Framework, for more information

see Communications Framework. </p>

<section><title> User prompt</title> <p>When comms UPS is implemented, the

user is requested to authorise a network connection, when an application opens

a new connection or when it attaches to an existing connection. The UPS prompts

the user when an application tries to send data through a socket which is

not explicitly associated with an authorised network connection. The IP network

user prompt is implemented as an MCPR plug-in. The plug-in will invoke the

UPS server. The UPS functionality can be configured by Symbian developers. </p> </section>

<section><title>UPS server</title> <p>The UPS server generates the user prompts

and responds back to the MCPR with the user selection. The dialog creator,

a UPS plug-in, formats and streams the dialog box to the UPS server. The UPS

server interacts with the User Interface (UI) and responds back to the MCPR. </p> <p>The

UPS server is also responsible for checking the policy files which has the

details of the process and the available options. </p> </section>

<section><title>UPS integrations</title><p><b>Messaging server </b> </p><p>The

Service UIDs used by the messaging server are:  </p><p><codeph>const TUid

KUidPOPService = {0x2000BB68};</codeph></p><p><codeph>const TUid KUidIMAPService

= {0x2000BB69};</codeph></p><p><codeph>const TUid KUidSMTPService = {0x2000BB6A}; </codeph></p><p><codeph>const

TUid KUidSendAs2Service = {0x2000BB6B}; </codeph></p><p><codeph>const TUid

KUidSMSService = {0x2000BB6C}; </codeph></p></section>

<section><title>Session life time</title> <p>When the comms user prompt service

component is configured for Session life time, user responds to a UPS dialog

prompt by authorising the request with either '<codeph>Session Yes</codeph>'

or '<codeph>Always</codeph>' response. Any other applications running in the

same process of the user authorised session will be granted network access

for the duration of the process. </p> </section>

<section><title>Network life time</title> <p>When the comms user

prompt service component is configured for Network session life time, user

responds to a UPS dialog prompt by authorising the request with either '<codeph>Session

Yes</codeph>' or '<codeph>Always</codeph>' response. Any other applications

running in the same process of the user authorised application will be granted

the network access. The UPS response for a particular process is valid for

the duration of the network connection associated with the process. </p> </section>
