public ShApplication()

Method Detail

init

public void init()
          throws DiameterException

Initializes the ShApplication. The hss host and realm can be configured with the application init parameters "destination.host" and "destination.realm" respectively. The "timeout" parameter can also be optionally used to specific the maximum number of milliseconds to wait for an answer from the HSS. By default, this is 30 seconds.

Overrides:

init in class ClientApplication

Throws:

DiameterException - if the initialization failed

getId

public ApplicationId getId()

Returns the Sh application identifier.

Specified by:

getId in class Application

Returns:

the Sh ApplicationId

getRepositoryData

public RepositoryData getRepositoryData(AccessKey key)
                                 throws DiameterException,
                                        IOException

Returns the RepositoryData for the specified Sh AccessKey. If the repository data does not exist then an empty RepositoryData instance will be created with a sequence number of 0. See 3GPP TS 29.328 v6.8.0 table 7.6.1 for details on data access key format.

Parameters:

key - the AccessKey for the requested data

Returns:

the RepositoryData for the key

Throws:

IllegalArgumentException - if not a repository data AccessKey

MessageException - if the answer from the HSS indicated an error

IOException - if an I/O error occurred

DiameterException

putRepositoryData

public void putRepositoryData(AccessKey key,
                              RepositoryData rd)
                       throws DiameterException,
                              IOException

Updates repository data for specified AccessKey.

Parameters:

key - the AccessKey for the data

rd - the new RepositoryData

Throws:

MessageException - if the answer from the HSS indicated an error

IOException - if an I/O error occurred

DiameterException

getDocument

public Document getDocument(AccessKey key)
                     throws DiameterException,
                            IOException

Retrieves the data associated with the specified AccessKey by sending a UDR request and waiting for the corresponding UDA.

Parameters:

key - the AccessKey for the data

Returns:

the data associated with the key, or null if not found

Throws:

MessageException - if the answer from the HSS indicated an error

IOException - if an I/O error occurred

DiameterException

putDocument

public void putDocument(AccessKey key,
                        Document doc)
                 throws DiameterException,
                        IOException

Updates data for the specified AccessKey by sending a PDR request and waiting for the corresponding PDA.

Parameters:

key - the AccessKey for the data

doc - the updated user data

Throws:

IllegalArgumentException - if the document format was invalid

MessageException - if the answer from the HSS indicated an error

IOException - if an I/O error occurred

DiameterException

subscribe

public void subscribe(AccessKey key)
               throws DiameterException,
                      IOException

Starts subscription for the data referred to by the specified AccessKey.

Parameters:

key - the AccessKey for the data

Throws:

MessageException - if the answer from the HSS indicated an error

IOException - if an I/O error occurred

DiameterException

unsubscribe

public void unsubscribe(AccessKey key)
                 throws DiameterException,
                        IOException

Unsubscribes from the data referred to by the specified AccessKey.

Parameters:

key - the AccessKey for the data

Throws:

MessageException - if the answer from the HSS indicated an error

IOException - if an I/O error occurred

DiameterException

createSession

public ShSession createSession()

Creates a new client ShSession.

Returns:

the ShSession for this application

setTimeout

public void setTimeout(long msec)

Sets the maximum number of millisecons to wait for an answer from the HSS. The default timeout is the request timeout value from the general Diameter configuration (30 seconds).

Parameters:

msec - the request timeout in milliseconds

getTimeout

public long getTimeout()

Returns the current request timeout.

Returns:

the request timeout in milliseconds, or -1 if the default request timeout should be used

rcvRequest

protected void rcvRequest(Request req)
                   throws DiameterException,
                          IOException

Called by the container when a new Sh request has been received. This request must be PNR since we are Sh client only.

Overrides:

rcvRequest in class Application

Parameters:

req - the Sh PNR requests

Throws:

DiameterException - if an error occurred while processing

IOException - if an I/O error occurred

rcvPush

protected void rcvPush(AccessKey key,
                       Document doc)

Called whenever a new PNR message has been received. This method should be overridden to provide handling of Push-Notification-Requests from the HSS.

Parameters:

key - the AccessKey for the user data

doc - the updated user data
