Aspects of the invention enhance the capabilities of the Message as a Platform ('MaaP') by adding interfaces thereto so that the platform directly interfaces with the Online Charging System (“OCS”), the Policy and Charging Rules Function (“PCRF”), the Equipment Identity Register (“EIR”), the Cloud Database (“COB”) and the Home Subscriber Server (“HSS”) without middle layer or without using Rich Communication Services (“RCS”) as an intermediary. Moreover, embodiments of the invention may create a user interface of the MaaP so that users may configure parameters to interact with the network nodes right from the user interface.

Enhanced messaging as a platform

Aspects of the invention enhance the capabilities of the MaaP by adding interfaces thereto so that the platform directly interfaces with the OCS, the PCRF, the EIR, the CDB and the HSS without middle layer or without using RCS as an intermediary. Moreover, embodiments of the invention may create a user interface of the MaaP so that users may configure parameters to interact with the network nodes right from the user interface.

A method and system for adding a notification to an error message. A first node and a second node are positioned in a communication network, and the first node is different from the second node. The first node is configured to process a network message before sending the network message to the second node. The first node encounters an error when processing the network message, and, before sending the network message to the second node, writes a reason of the error in a header section of the network message. The first node is configured to send the network message to the second node with the header section.

System and method for enhancing identification of network node initiator errors

Architecture is described for providing interfaces between a presence server and a Policy and Charging Function (PCRF) node, an Online Charging System (OCS) node, and an Equipment Identity Register (EIR) node. Techniques are also described for determining, by the presence server, various potential rules and limitations for providing services by the wireless communication network to mobile devices based upon, for example, a particular subscriber plan, roaming, restrictions based upon mobile device type, a need for throttling of data to a mobile device, specific billing rules, etc.

Controlling services provided to mobile devices within wireless communication networks

Systems and methods are described herein for handling E911 communications within IMS networks, such as Voice over LTE (VoLTE) networks. In some embodiments, the systems and methods, via various communication nodes, handle or otherwise govern emergency calls within the VoLTE network, by sending an INVITE message from a sender node of the VoLTE network to a recipient node of the VoLTE network, and starting a retry timer at the sender node that is specific to handling E911 calls by the VoLTE network.

Emergency call handling within IP multimedia system (IMS) networks

An application function (AF) of an IP Multimedia Subsystem (IMS) can be in communication with multiple Policy Control Function (PCF) domains of a telecommunication network. The AF can review attributes of a particular communication session, and identify a particular one of the PCF domains that corresponds to the attributes. The AF can then send a request about the communication session to a PCF element of the identified PCF domain over an Rx interface.

Optimized policy control function mapping for application function

Nodes within a wireless communication network monitor themselves as they come back online after crashing, i.e., go back into service, or when they initially go into service. When the node is activated for service within the wireless communication network, the node has a predefined capacity of resources available to user devices at the node. Thus, when a node goes into service, the node may initially limit itself to utilizing only a portion of its capacity of resources. In other embodiments, the node may limit the user devices allowed to access the node to a particular number of user devices. After a predetermined amount of time, or once the node is stable, the node may allow for more user devices to access the node.
