Detailed Description

Class for managing audio/video and measurement data distribution from mobile emergency clients to the associated call center clients. Data packets from mobile emergency clients can be relayed in a fan-out style to multiple call center connections. Data subscriptions for each call center connection are stored in the "dataSubscribers" dictionary.

<author>Veli-Mikko Puupponen</author> Data packets from call center clients to the mobile emergency clients are enqueued in a call center client specific queue from which the mobile emergency client that the call center client is currently processing is able to fetch them.

Contains an instance of UdpMediaRelayServerCore that manages the UDP based media data transfer.

Member Function Documentation

void Disable ( )

Disables the UdpMediaRelayServerCore to release its undelying UDP socket.

AudioVideoContainerDto MobileClientGetAudioVideoFromPublishQueue ( string mobileGuid )

Returns audio and video media published by a call center connection. If the publishing queue for the call center client associated with the calling mobile emergency client, this method returns an empty AudioVideoContainerDto. Otherwise returns the AudioVideoContainerDto from the from of the media queue.

Parameters

mobileGuid Guid of an existing emergency mobile client that is connected to the server.

Returns: AudioVideoContainerDto that constains audio//video data, if available. Otherwise it is empty.

bool PublishCallCenterClientAudioVideo	(	CallCenterConnectionDto	user,
		MediaInformationDto	mediaInfo,
		byte[]	mediaData
	)

Publishes audio and video from a call center client to its client specific queue. This data can be asynchronously read by the remote mobile emergency client over its WCF connection.

Parameters

user	CallCenterConnectionDto describing the publishing call center client
mediaInfo	MediaInformationDto describing the published media data
mediaData	Media data

Returns

void PublishMobileClientAudioVideo	(	string	mobileGuid,
		MediaInformationDto	mediaInformation,
		byte[]	mediaPayload
	)

Performs fan-out distribution of audio/video data received from a mobile emergency client with the specified GUID. The data is distributed to the call center clients that have subscribed for data from mobile client using the specified GUID.

Parameters

mobileGuid	GUID of the mobile emergency client connection providing the audio/video
mediaInformation	Description of the audio/video data
mediaPayload	Audio/video payload data

void PublishMobileClientInstrumentData	(	string	mobileGuid,
		MeasurementInstrumentDto	measurementInstrument,
		byte[]	measurementPayload
	)

Performs fan-out distribution of measurement data received from a mobile emergency client with the specified GUID. The data is distributed to the call center clients that have subscribed for data from mobile client using the specified GUID.

Parameters

mobileGuid	GUID of the mobile emergency client connection providing the data
measurementInstrument	Instrument producing the measurement data
measurementPayload	Measurement data from the instrument

void SubscribeCallCenterClientForData	(	CallCenterConnection	callCenter,
		Connection	mobileClient
	)

Parameters

callCenter	The subscribing call center client
mobileClient	The mobile emergency client from whon the data is subscribed from

void UnsubscribeCallCenterClientForAnyData ( CallCenterConnection callCenter )

Unsubscribes the call center client from audio/video and instrument measurement data sent by any mobile emergency client. Also removes queues and mappings for publishing data from the call center client to any mobile emergency client.

Parameters

callCenter The unsubscribing call center client

void UnsubscribeCallCenterClientForData	(	CallCenterConnection	callCenter,
		Connection	mobileClient
	)
