Abstract: A system described herein provide for the secure maintaining and providing of information, such as public keys used in Public Key Infrastructure (“PKI”) techniques or other techniques, using a secure distributed ledger (e.g., “blockchain”) system. A first entity may generate an asymmetric key pair that includes a public key and a private key, and may provide the public key, along with a key identifier, to a blockchain system for retrieval by multiple other entities. For example, the entities may be engaged in a secure group communication session, in which communications are encrypted and may be decrypted using one or more keys, including the public key. The other entities may identify the public key, as recorded to the blockchain system, based on the key identifier. Participants may be added to or removed from the secure group communication session.

Abstract: A device may receive, from a user equipment, a token request associated with an application, wherein the token request is associated with a device identifier. The device may generate a device token for the application and the user equipment. The device may provide, using the device identifier, the device token to the user equipment to enable a user to access the application via an application platform. The device may receive, from the application platform, a slice request for a network slice of a network that is to be used for an application session. The device may determine that the user equipment is associated with the application session based on the device token and the device identifier. The device may configure a network slice instance of the network slice. The device may determine a user equipment route selection policy for the application session according to the network slice instance.

Abstract: A network device receives an indication to establish a session for an internet protocol (IP) service between a first device and a second device, wherein the network device is part of a local network with the first device and another network device. The network device identifies a service tag to include in a service tag field of a session request. The other network device causes the session request that includes an updated service tag to be provided to the second device. The second device provides a session response with the service tag to the other network device, the other network device updates the session response to include the original service tag and provides an updated session response to the network device. The network device causes the session to be established.

Abstract: A user device registers with a proxy-call session control function device (P-CSCF) associated with an Internet protocol (IP) multimedia subsystem (IMS). The user device forwards a request to the P-CSCF requesting a session via the IMS for an IMS call. If a response to the request is not received from the P-CSCF during a time period after forwarding the request, the user device attempts to newly register with the P-CSCF. If the new registration is successful, the user device re-forwards the request to the P-CSCF. Otherwise, if the new registration with the P-CSCF is unsuccessful, the user device registers with a different P-CSCF and forwards the request to the second P-CSCF.

Abstract: A device determines whether a PTT application is authenticated to access a first API and a second API, and prevents the PTT application from accessing the first and second APIs when the PTT application is not authenticated. The device permits the PTT application to access the first and second APIs when the PTT application is authenticated, and modifies, via the first API, a timer that dictates when the device checks for traffic received from a network. The device establishes, via the second API, a data connection with the network, and determines, based on the data connection, a QoS framework for the network. The device utilizes the PTT application and the timer to establish a PTT session with another device via the network, and prioritizes, based on the QoS framework, PTT traffic provided in the PTT session with the other device.

Abstract translation: 设备确定PTT应用是否被认证以访问第一API和第二API，并且当PTT应用未被认证时，防止PTT应用访问第一和第二API。 当PTT应用被认证时，该设备允许PTT应用访问第一和第二API，并且经由第一API修改定时器，该定时器指示设备何时检查从网络接收到的流量。 该设备通过第二API与网络建立数据连接，并且基于数据连接确定网络的QoS框架。 该设备利用PTT应用和定时器经由网络与另一设备建立PTT会话，并且基于QoS框架优先考虑PTT会话中提供的PTT流量与另一设备。
