Media, methods and systems are provided for coordinating changes of network sources for media streams in a telecommunications network. The streams communicate instances of media content via packets to devices. A first network source streams packets of an instance of media content to a device. Each packet includes information regarding the temporal ordering of that packet within the instance and information regarding the sequencing of the packet within the stream. It is determined that a second network source should stream the instance of media content. A point in the temporal ordering within the instance is identified and communicated at which the second network source will provide the instance of media content. The second network source streams to the mobile device the instance of media content from the identified point, without requiring adjustment of the information regarding the sequencing of the packets within the stream.
