Introduction 5G is ON.

2019 is the 12 months for 5G commercialization, a yr the place leading operators are beefing up 5G deployment to right away launch greater-pace 5G statistics features (notwithstanding 5G presents tons more than that), and appeal to greater users. Voice functions, one of the most simple capabilities for operators, additionally carry international operator problem about its construction and evolution in the period of 5G, the connection between Voice over LTE (VoLTE) and Voice over 5G (Vo5G), and voice community evolution towards future.

IMS-primarily based 5G Voice capabilities 5G will continue to utilize 4G voice structure and the IP multimedia subsystem (IMS) to deliver voice capabilities. For 4G instant access we have LTE networks, and its voice carrier VoLTE. The 5G such as LTE is NR, and its voice carrier equal is Voice over NR (VoNR).

3GPP has defined how voice solutions will be applied in 5G networks (as in the past mentioned) after the free up of requirements for the Non-Standalone (NSA) architecture in December 2017, and the standalone (SA) architecture in June 2018. In July 2018, Huawei launched the Vo5G Technical White Paper. This white paper units the definition for Vo5G, and describes its key applied sciences. The white paper additionally defines a direction for evolution against VoNR and gives information for its implementation, such as deployment of IMS to accelerate subscriber migration to VoLTE networks.

VoLTE is a ought to for Vo5G In a technological experience, 5G period voice services will exist in three types: IMS voice through 5GC, IMS voice via EPC, and CS voice through MSC. To examine it in this way is just too essential and does not imply a good deal.

So via altering the perspective and searching at it in terms of carrier deployment and the voice event of clients, we can greater take note the way to choose voice solutions for different levels of 5G.

  • 5G NSA part: it is foreseeable that most operators will delivery by using launching 5G functions in NSA mode. earlier than launching 5G capabilities, these operators will deliver voice functions for 4G subscribers through CSFB or VoLTE, while still maintaining voice services for 2G or 3G subscribers in the course of the CS community. When 5G features are launched, operators should still, via default, permit VoLTE capabilities for 5G NSA subscribers. in any other case, clients will should fall returned to the 3G network when making and answering calls. This fallback would lower the bandwidth from 5G to 3G speeds (as much as a 100x lessen), and it might also imply an expanded time to establish a name. during this case, users would not basically be capable of totally event the astonishing journey that can be provided with the aid of 5G, and instead would see a degraded edition. this may be despite their willingness to pay for enhanced 5G, and despite them switching to a 5G capable terminal and cell plan.
  • 5G SA preliminary part: If 5G NSA subscribers do not subscribe to VoLTE capabilities, they are going to adventure the "degraded" 5G experience. If a 5G SA subscriber doesn't subscribe to the VoLTE carrier in the 5G SA phase, the subscriber can't initiate or obtain voice calls. this is unacceptable. As described in 3GPP R-15, CS fallback from 5G to 2G/3G is not supported. This capacity that once a voice call is set up, 5G SA networks should still use evolved Packet gadget Fallback (EPS FB) know-how for voice fallback to the LTE community, completing the connection through VoLTE.
  • 5G SA mature phase: NR insurance could be extra finished during this section than within the preliminary part, however won't have reached full insurance. The trade, above all within the case of terminals, will should mature. Terminal support for 5G SA will should turn into mainstream, and their default configuration will deserve to be for VoNR (set to ON with the aid of default), the then main issuer of voice functions. When the user moves backyard of 5G insurance all over a name, Packet Switched Handover (PSHO) technology will also be used to seamlessly change the session from the NR to the LTE, leaving VoLTE to take over voice features. (this is comparable to the single Radio Voice name Continuity (SRVCC) in 4G, but the ideas are distinct.) as a result of session control on 4G and 5G networks is built-in into the IMS for processing, a fancy pass-device (like from 4G to 2G/3G) SRVCC handover manner can be prevented. an easy PSHO is carried out only within the entry domain to change the transport, fighting the higher control layer from perceiving it. therefore, VoLTE may still be developed as a primary, ubiquitous community with full insurance in this part, in order that the 2G/3G network can also be retired to store operation costs and unlock spectrum materials.
  • To sum up, VoLTE is mandatory for 5G deployment and building. it's vital that operators increase VoLTE investment, now not only for community deployment, but additionally to accelerate subscriber migration to VoLTE.

    Accelerating Voice Migration to VoLTE for community and Spectrum efficiency The VoLTE business has already matured. There are more than billion VoLTE subscribers, on more than 170 global commercial networks, and greater than 2000 VoLTE terminals.

    The most advantageous path for operators to enhance the value of VoLTE is to simplify the community and coordinate spectrum components. The 2G/3G community is to be progressively retired from the community (including the wireless community and core network) to reduce OPEX and simplify the community. As more and more subscribers are migrated to VoLTE networks, spectrum substances (especially scarce, helpful low-frequency spectrum elements) used for CS voice functions will be released and refarmed for new functions similar to LTE or NB-IoT, enhancing spectral effectivity.

    besides the fact that children the VoLTE trade is mature and operators be aware of the price of VoLTE, it isn't easy emigrate such a huge variety of subscribers from the CS community to the VoLTE network. greater than 170 operators have deployed commercial VoLTE capabilities, and a few of them have been in industrial use for at the least two years. despite the fact, there is not satisfactory subscriber uptake. Most complaints cause the proven fact that there are too few terminals aiding VoLTE on these networks. they have got purpose to complain.

    youngsters greater than 2000 VoLTE terminals (hardware support) have been deployed, no longer all of these terminals may also be used on any VoLTE industrial network. additionally, terminal carriers deserve to supply utility types that correspond to the target VoLTE community. although the hardware of older fashions supports VoLTE, terminal vendors continually only deliver this application for his or her more recent fashions. This requires extra cooperation and negotiation between operators and terminal vendors.

    apart from the challenges from terminals, LTE coverage is insufficient and VoLTE features are complicated to provision precisely. here's an incredible element within the lower than swift construction of VoLTE clients. however, essentially the most critical component in solving these challenges, lays frequently within the arms of operators, and their resolution to strengthen VoLTE competent networks.

    Operators should treat VoLTE as a strategic carrier for the construction of 5G in preference to an alternative to standard voice capabilities, bring forth colossal-scale community simplification, reintegrate spectrum resources, coordinate excessive nice components (each price range and manpower), optimize networks, introduce new terminals, and provision new features. This method has been proven and verified by using many operators as a certain fireplace method to advertise speedy construction of VoLTE subscribers.

    Evolving to a 'Single Voice Core' in the subsequent 5 Years to in the reduction of OPEX In guidance for 5G, operators should enhance their investment in VoLTE, build VoLTE right into a ubiquitous, basic voice community, accelerate person migration to VoLTE, and simplify community and spectrum integration.

    With the introduction of 5G voice functions, voice network belongings gradually accumulate, bringing higher OPEX to operators. apart from the IMS-VoLTE and Vo5G voice networks, CS voice networks will coexist with VoLTE for a very long time. For operators seeking to deliver complete voice capabilities, there are three more fastened networks: PSTN, NGN, and IMS-VoBB. The coexistence of five voice networks brings the following challenges: added preservation and management of dissimilar generations of hardware equipment (notably EOX administration), prices from scattered gadget rooms, and labor fees for protecting administration of numerous networks. it is time to take action for the long run, to restructure and optimize existing voice assets.

    As a solution, Huawei proposes the "Single Voice Core" solution alongside auxiliary solutions to support operators simplify their five voice networks into one, and in the reduction of OPEX.

    "Single Voice Core" makes use of a mix of "full cloudification" and "full convergence" to simplify the voice community, integrating all voice connections into IMS, cutting back OPEX, and accelerating the rollout of latest capabilities.

  • Full cloudification: Huawei provides a full range of "All-cloud" E2E voice options and product combinations with excessive reliability and flexibility. among these is the industry's first cloud-primarily based media airplane product CloudSE2980. This product moves media to the cloud unexpectedly, combating substitute of the media airplane that may take place with a normal platform (for instance, EOX replacement of MGW products.) substitute of this platform with a cloud-based mostly platform is a should for the future. As voice network assets are gradually moved to unified cloud-primarily based hardware, OPEX will reduce greatly.
  • Full convergence: extra converged products can definitely convey a simplified network architecture. Huawei gives converged products on the voice handle plane, gateway change, and media aircraft. The capabilities of dissimilar NEs will also be supplied with just one converged product. This helps operators cut back the change nodes on the network, reduces reliance on IT integration interfaces for bringing new features online, and reduces the manpower required for O&M, thereby bringing sooner provider rollout and lowered operation charges.
  • Conclusion 5G voice will still utilize the IMS structure of the 4G VoLTE voice community, so Huawei suggests that operators pay attention to right here:

  • As is, the 4G VoLTE voice network should still be deployed as a simple community for voice services that covers the complete network to speed up the migration of subscribers to the VoLTE network and prepare for the smooth evolution to Vo5G. Huawei's VoLTE solution has been commercially launched by means of more than 60 operators international, serving greater than 400 million users. Leveraging mature solutions and huge experience in implementations, Huawei is capable of help operators directly install and commercialize VoLTE networks, ramp up subscriber migration to VoLTE, and easily evolve to Vo5G.
  • in the end, simplification of the voice community and decreased OPEX will include the evolution of the voice network to a full-cloud, and absolutely converged voice community — "Single Voice Core". Huawei gives a full range of end-to-end product portfolios for Single Voice Core evolution, and is dedicated to working with operators to optimize voice assets and evolve in opposition t the longer term.
