While paving the way for continuous growth in revenues, the advent of 6G and the explosive growth in the number of 5G and LTE connections also present new challenges for mobile operators. 5G provides lower latency, higher speeds and new IoT applications, resulting in increased subscriber sessions.
Rapidly rising subscriber sessions require intelligent traffic forwarding to support dynamic rules and policies within the core network. This in turn relies on session and subscriber awareness, enabling operators to distinguish user identities and ascertain user attributes, such as location information and device ID, in real time across each flow. Session and subscriber awareness help operators steer each session intelligently, ensuring a superior and consistent user experience, in alignment with plan SLAs and application KPIs.
Without session and subscriber awareness, the mobile core becomes inundated with millions of concurrent sessions that are forwarded arbitrarily via standard load balancing, with each session processed in fragments by different machines. This entails extensive reconciliation and redundancies within each network subsystem, leading to delayed policy responses, additional latency and poor application performance.
GTP in 5G mobile networks
GTP (GPRS Tunneling Protocol) is a specific type of tunneling protocol tunnel which is used in GSM, UMTS and LTE mobile networks to transport GPRS packets within the network infrastructure. GTP is also responsible for carrying data traffic between roaming or home subscribers and network interfaces in 5G, making it the ideal technology to meet growing network requirements.
GTP correlation by ipoque empowers mobile networking solutions to reliably identify subscribers and sessions while also ensuring subscriber security and optimizing your network capacity.
Introduce intelligent load balancing for your mobile core by leveraging GTP and 5G correlation for full visibility into each session. Equip your load balancers and physical and virtual machines with real-time subscriber awareness and bring your network performance and security to the next level.
Level up your network performance with GTP and 5G correlation
ipoque’s GTP traffic correlation software, R&S®GSRM, and its 5G correlation counterpart, R&S®5GSRM (to be launched soon), are built on the latest advancements in user plane and control plane traffic analysis. Both techniques correlate control traffic (GTP-c) attributes, such as IMSI, MS-ISDN and IMEI, and interface types, such as S3, S4, S5, S8, S11, S16, S2a, S2b, Sm, Sv, Gn, GP and Ga, with user traffic (GTP-u) Tunnel Endpoint Identifiers (TEIDs). Real-time session identification by R&S®GSRM and R&S®5GSRM enable your network packet brokers, network probes and other packet processing functions to tag and log packets with subscriber identification information, and filter and forward packets using session- and subscriber-based rules. It allows all packets from a single session to be forwarded in a single flow and in the right sequence, providing network subsystems full visibility into user sessions.
Subscriber awareness provided by R&S®GSRM and R&S®5GSRM helps mobile operators keep tab of the performance of each session and application, resolve issues on the subscriber-end faster, implement traffic prioritization based on plan types, expedite threat detection, and control fraud and abuse. Rely on R&S®GSRM’s and R&S®5GSRM’s seamless integration and light form-factor to keep 3G, LTE and 5G networks “subscriber-aware” for a greater network experience.
