7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 6.3.3 Open service API | It shall be possible to bind third-party service notes to a session server for the purposes of providing service features over and above the basic service. This binding may be performed during registration or possibly later. These feature servers will be interrogated when the event they are registered for occurs. End-u... |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 7 Bearer establishment | The session control protocol shall be used in conjunction with a media control protocol that describes the mono or multi media session. Such a media control protocol may be encapsulated in the session control protocol (e.g. SDP and SIP) or invoked in parallel (e.g. H245 and H225). During the session initiation request,... |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 7.1 Successful bearer establishment | Successful bearer establishment must include the completion of any required end-to-end QoS signalling, negotiation and resource allocation. |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 7.2 Network intervention | Both the access and the service call server shall have access to the requested media session parameters (e.g. for charging or resource management purposes). The network shall have the possibility to participate in the media session parameters negotiation for the purposes of indicating that this session may or may not b... |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 7.5 Resources allocation | In establishing a session, it must be possible for an application to request that the resources needed for bearer establishment are successfully allocated before the destination user is alerted. |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 7.6 Early media | Early media refers to media that is exchanged before a particular session is accepted by the called user (e.g. announcement). Support for early media is required. |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 8 Accounting | It shall be possible to account for session usage. The usage shall be reported containing session duration as well as session type, media flows supported (type and quality) and session participants. |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 9 Charging | On-line charging shall be possible. This means that the capability shall be able to generate appropriate accounting records in real-time. The means of (conveying) this charging is outside the scope of the present document. |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 10 Security requirements | |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 10.1 Authentication | An end user shall be authenticated at registration time before the use of signalling resources is authorized. The Service call server is responsible for authenticating the end user. As a consequence, the authentication method must be able to work when there are signalling entities (e.g. the Access call server) in the s... |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 10.2 Message protection | Signalling entities (end user terminals and network entities) shall be able to communicate using integrity protection (ability to verify that the message has not been modified by a non authorized party) and replay protection. Signalling entities (end user terminals and network entities) shall be able to communicate con... |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 10.3 Delegation | It must be possible to perform an initial authentication of the end user based on long-term authentication credentials, followed by subsequent protected signalling that uses short-term authentication credentials, such as session keys initialized during initial authentication. The used authentication mechanism is able t... |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 10.4 Establishment of mechanisms | A method must be provided to securely establish the security mechanisms to be used between the end user terminal and the Access call server. |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 10.5 Verification of messages | |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 10.5.1 Verification at the Access call server | The Access call server must be able to guarantee the message origin and verify that the message has not been changed (e.g., it is integrity protected). |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 10.5.2 Verification at the Service call server | The Service call server needs to receive an indication if the Access call server was able to verify the message origin and whether it was integrity protected or not. |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 10.5.3 Confidentiality | Mechanisms shall exist so that messages may not be read by unauthorized third parties. |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 10.5.4 Prevention of denial of service | The risk of a call server to receive a denial of service attack shall be minimized. For instance, a malicious device could learn a call server IP address and port number and establish an attack to that call server. |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 10.5.5 Hiding requirement | The signalling messages that are sent between administrative domains shall reveal the least information possible about the underlying network configuration. A network operator need not be required to reveal the internal network structure to another network. A network operator need not be required to expose the explicit... |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 11 Emergency sessions | The establishment of an emergency session by a user shall be technically possible even if this user is not registered and not authenticated. NOTE: Local regulations may prompt a service provider to disable this aspect and hence it shall be possible to disable this for all or particular groups of terminals. ETSI ETSI TS... |
7155d9633c735a23b3bf00122d45e1b3 | 181 010 | 12 Lawful interception | Sessions shall allow for lawful interception. Depending on the local regulations and the mandates given to the law enforcement officers the session meta-data and/or the media flows shall be available in real-time. • Meta-data shall contain the presentation identities of the participants as well as the unique identifier... |
