The present disclosure is directed, in part, to improving communications by using multiple TCP ports, substantially as shown in and/or described in connection with at least one of the figures, and as set forth more completely in the claims.
Real-time network services, including Voice over LTE (VoLTE), Voice over 5G radio (VoNR), 911 call over VoLTE, 5G New Radio (NR), and Rich Communication Services (RCS) messaging, are designed to deliver real-time information with a high quality of service in a timely manner. In conventional communication systems, a user device utilizes a single transmission control protocol (TCP) port for session setup of a real-time network service. From time to time, a user device utilizing one or more real-time network services can lose radio connection with a mobile network, such as but not limited to when the user device is located on a cell edge of a mobile network or in a fringe area where signal reception is weak and/or subject to distortion. Once the user device regains a radio connection, however, the TCP port that the user device is utilizing may no longer be available for setting up a real-time network service between the user device and the mobile network. As such, the user device may experience a reduction in the quality of or outright failure of one or more of its real-time network services. By using a particular methodology that allows for the use of multiple TCP ports, however, the user device will be able to alleviate this reduction in quality of or outright failure of its real-time network services.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used in isolation as an aid in determining the scope of the claimed subject matter.
Illustrative embodiments of the present invention are described in detail below with reference to the attached figures, which are intended to be exemplary and non-limiting, wherein:
The subject matter of embodiments of the invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this patent. The claimed subject matter might be embodied in other ways to include different steps or combinations of steps similar to the ones described in this document, in conjunction with other present or future technologies. Terms should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly described.
In certain aspects, methods are provided for improving communications by using multiple TCP ports. A data packet is sent using a first TCP port of a plurality of TCP ports.

At block 204, a UE device determines that the data packet sent using the first TCP port was not received by a receiving device. For example and without limitation, after the UE device sends the data packet, such as but not limited to, a SIP INVITE request, the UE device determines that the data packet sent using the first TCP port was not received, such as but not limited to, if the UE device does not receive a 200 OK message in response.
Once the UE device determines that the data packet sent using the first TCP port was not received, the UE device may use a different TCP port. In specific embodiments, the UE device may utilize another TCP port different from the first port number within the range of Registered Port numbers or Dynamic Port numbers. In certain embodiments, the UE device can be pre-configured with a plurality of TCP port numbers that can be used to re-send a data packet when it is determined that the data packet sent using the first TCP was not received. At block 206, the UE device re-sends the data packet using the second TCP port.
In some embodiments, the UE device determines that the data packet sent using the second TCP port of the plurality of TCP ports was not received by a receiving device. The UE device then re-sends the data packet using a third TCP port of the plurality of TCP ports. In further embodiments, the second TCP port is a Registered port and the third TCP port is a Dynamic port. And in still further embodiments, the third TCP port is a Dynamic port in the range of 60000-65565. The UE device in other embodiments can be preconfigured with at least two TCP ports that are ranked as a first port, second port, etc. When the UE device determines that a data packet has not been received, it utilizes the TCP port ranked as the first port to send the data packet. When the UE device determines that the data packet has not been received using the TCP port ranked as the first port, it utilizes the TCP port ranked as the second port to re-send the data packet.
In other embodiments, the UE device determines that the second TCP port is not available to send the data packet. The UE device identifies a third TCP port from the plurality of TCP ports that has availability to send the data packet, wherein the first, second, and third TCP ports are different. The UE device then re-sends the data packet using the third TCP port. In specific embodiments, the second TCP port is a Registered port and the third TCP port is a Dynamic port.
In certain embodiments, the UE device is equipped with a retry timer. When a UE determines within a certain time period between anywhere from approximately 500 milliseconds to 16 seconds, that a data packet has not been received by a receiving device on a first TCP port, it re-sends the data packet using a second TCP port. In other embodiments, when a UE device determines within a certain time period between anywhere from approximately 500 milliseconds to 16 seconds that the data packet using the second TCP port has not been received by a receiving device on a second TCP port, it re-sends the data packet using a third TCP port.
