Authorization for access to an application server and associated communication service can be desirably managed. When a device attempts to access an application server and service, an authorization server generates an encrypted token, comprising device identifier information, and communicates the token to the device. The device communicates the token to the application server. The application server communicates the token to the authorization server. The authorization server determines whether the device is validated to access the application server and service based on the encrypted token, private decryption key, and initialization vector, and based on subscriber-related information. The authorization server does not share the private decryption key or initialization vector with the application server. If validated, the authorization server communicates validation-related information, including a permitted portion of subscriber-related information, to the application server. If not validated, the authorization server communicates not-validated information to the application server.

Service and security enhancement of communication services

The technologies described herein are generally directed to facilitating operation of system that can include a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. In embodiments, the operations can include receiving, from a source user equipment, a first request to communicate to a destination group of user equipment via a multi-cast connection. Further operations can include identifying respective service areas of ones of the destination group, comprising a service area of a destination user equipment of the destination group. In some embodiments, operations can include generating a second request to initiate the multi-cast connection, the second request comprising the destination group of user equipment with the respective service areas, wherein the respective service area of the destination user equipment is for selection, by second network equipment based on the service area, a gateway group of base station equipment.

A method and system for converting data message formats in a message server is provided. The message server receives a first data message including origin format information from a first user. The message server then sends the first data message including origin format information to a second user. The message server receives a second data message from a second user, the second data message including the origin format. The second data message is converted to the origin format if the first user is unable to receive the second data message. The message server then sends the converted second data message to the first user.
