Problems solved by technology

[0003] Also, most older implementations (which are more numerous and only support IPv4) do not tolerate the use of IPv6 addresses in SIP messaging
Such implementations may not work correctly, or in the worst case may crash if IPv6 addresses are included in SIP messages instead of handling IPV6 addressing

Embodiment Construction

[0023] figure 1 is an illustrative block diagram of a first illustrative system 100 for handling IP version intolerance. A first illustrative system 100 includes communication endpoints 101A- 101N, a network 110 and a communication system 120 .

[0024] The communication endpoints 101A-101N may be or include any communication endpoint device capable of communicating over the network 110, such as a personal computer (PC), telephone, video system, cell phone, personal digital assistant (PDA), tablet device, notebook device, web server, media server, smartphone and / or etc. Communication endpoints 101A-101N are devices on which a communication session ends. The communication endpoints 101A-101N are not network elements, such as communication managers or routers, that facilitate and / or relay communication sessions in the network. like figure 1 As shown, any number of communication endpoints 101A- 101N may be connected to network 110 . Communication endpoints 101A-101N may be...

Abstract

The present disclosure relates to IP tolerance and signaling interworking. The first message is received while attempting to establish a communication session between the first communication entity and the second communication entity. For example, the first message may be a SIP INVITE message. Based on the registration message from the first communication entity and / or the second communication entity, it is determined that at least one of the first communication entity or the second communication entity is Internet Protocol (IP) version intolerant. In response to determining that the at least one of the first communication entity or the second communication entity is IP version intolerant, one or more IP addresses in a message (eg, a SIP INVITE message) are adapted to establish a communication session. This adaptation removes / changes one or more IP addresses to different IP versions to ensure correct IP compatibility.

Description

Background technique [0001] Internet Protocol (IP) version 4 (IPV4) is a network layer protocol that provides communication capabilities over the Internet. In IPV4, each IP address is 32 bits long, allowing 4.3 billion unique addresses to identify a device. With so many mobile communication devices in use now, additional IP addresses are needed before the IPV4 addresses are exhausted. Internet Protocol Version 6 (IPv6), a replacement for IPv4, increases the number of available IP addresses by changing the way addresses are allocated. In IPv6, IP addresses are 128 bits long. [0002] An existing Request for Comments (RFC) for the Session Initiation Protocol (SIP) states that newer IPV6 schemes need to take IPv4 addresses into account, while older IPv4 implementations must also support both IPv4 and IPV6. Although many newer implementations support both types of IP addresses when the administered address is IPv4 or IPv6, this approach is not universal. In other words, in som...
