MNO Cloud Use Cases 4 to 9

This document outlines a list of potential cloud use cases relevant to MNOs, including filing sharing services, hosting a cloud server, proxying through a cloud server, dynamic triggering, and enterprise extensions to the cloud.

  2. Introduction • This document provides additional use cases • Refer to documents Tdoc SA3LI11_103 Tdoc SA3LI11_104, SA3LI11_115 and SA3LI11_116 for background material

  3. List of Potential Cloud Use Cases relevant to LI Work • Use Case 1: Filing Sharing Service with single MNO • Use Case 2: MNO uses a Cloud server • Use Case 2a: MNO uses a Cloud server that provides redirection • Use Case 3: The MNO hosts a cloud in its network • Use Case 4: SMB or Enterprise use multiple MNO networks • Use Case 5: Same as Use Case 4, but each MNO has a Cloud Server that proxies (extension of Use Case 2) • Use Case 6: Same as use case 6, however MNO cloud server provides redirection (extension of Use Case 2a) to the 3rd party cloud App server • Use case 7:Dynamic triggering (extension of use case 4) (new) • Use Case 8: SMB or Enterprise use multiple MNO with their own Clouds (extension of Use Case 4) • Use Case 9: Enterprise extension to the cloud • Future Use Cases ; Local Break out, Femto

  4. Use Case 4 • SMB or Enterprise use 2 or more MNO for their users (licensing in a country ie province, State or city requires 2 or more MNO to provide coverage, business reason (diversity, business continuity, costs) • Each MNO has a white label with the same 3rd party Cloud Service (same as use case 1) • Each MNO will capture traffic for the target while they are on it’s network. • Assume only one warrant issued against MNO where the target has a subscription • Roaming traffic is assumed to go home in MNO to MNO IPX • Captures traffic while roaming in other regulatory domains • Traffic while on internet cafe is not captured by the MNO • Local break out for a target roaming may not be captured either • Each MNO may use different Keying material for secure access and storage of files (client application)

  5. Use case 5 • Same as Use case 4, but each MNO has a Cloud Server that proxies (use case 2) • DNS • May route to the wrong MNO Cloud Server • (users that change MNO) • Each MNO may have initialization strings to provide the URL that resolves to the correct URI from the DNS • Each MNO may use different Keying material for secure access and storage of files • (issue on the cloud on handling, the cloud could provide a common key to be used, however file will look encrypted to LEA) • As MNO proxies, all is captured • Internet cafe, LIPA and SIPTO

  6. Use case 6 • Same as use case 5, however MNO cloud server provides redirection (use case 2a) to the 3rd party cloud App server • Keying material from each MNO may be different when accessing the same files for different users • Each proxy may behave differently for LI

  7. Use case 7 • Same case Use case 4 with a dynamic trigger function in the Cloud Server • May only work if in the same regulatory domain, (MNO and Cloud Service) • Requires Inter-Regulatory Domain agreements if operated across domains

  8. Use case 8 • Same as Use case 4 but supporting multiple MNO with their own Cloud • Example is MNO Cloud Services which are made available to other MNOs • CDN, eg Mobile TV content, Media • M2M services • Financial services • File services • Large carriers providing regional or small carriers access to service • Ie customers that roam • Carriers providing global services to other carriers

  9. Use case 8 • Implementation issue • Is does request bypass home cloud (via VPN) • Is the content delivered encrypted to the User via Session key encryptions, thus providing encrypted content to LEA • Is it handled like case 2, case 2a, or a combination

  10. Use case 9 • Enterprise extension to the cloud • Can access the enterprise and or the cloud • Does this collapse to a vpn solution provided by the mno? • Issue VPN / SSL usage • Will enterprise allow Split access from vpn client?

  11. Future Use case • Sipto, LIPA, and femto use case required • Femto with internal cloud service/ Apps
