CPH Advantages

CPH relies on Huawei Cloud servers, innovative technologies, and peripheral services to enable mobile applications to run on the cloud. Compared with common mobile phone simulation solutions, CPH has outstanding performance, compatibility, and stability.

First in the Industry

It is the first Arm-based CPH solution in the public cloud industry. Both terminal devices and CPH have Arm inside. Native applications require no instruction set translation. Cloud phone applications are highly compatible, and their operating performance can be improved by up to 80% compared with the x86 emulator solution. Also, professional GPU acceleration is available to run large-scale games without pressure.

Enhanced Security

Depending on the clustered deployment and operation capabilities of Huawei Cloud, CPH seamlessly interconnects with multiple public cloud services, supports user data mounting within seconds and data persistence. It processes data on the cloud, which is more secure and more powerful to handle enterprise-level large-scale applications.

Cloud-based upgrades will make CPH always stand out among its peers while eliminating depreciation cost.

High Flexibility

Cloud phones can be customized as needed and be purchased on demand to better handle uncertain enterprise service developments. Cloud phones can be provisioned in batches. You can manage them with ease. For instance, you can batch restart, reset, power on, or power off them.

Upgraded Security

CPH service data is stored on the cloud instead of being on premises. It is secure with protection from security services including Anti-DDoS and Situation Awareness.

Comparison Between CPH and Other Mobile Phone Simulation Solutions

Common mobile phone simulation solutions in the market include the x86 emulator solution and mobile phone teamwork control solution. Table 1 lists the advantages and disadvantages of the three solutions.

**Table 1** Comparison between CPH and other mobile phone simulation solutions
Dimension	x86 Emulator	Physical Phone	Cloud Phone of Huawei
Performance	Poor Conversion between x86 and Arm instruction sets is required, resulting in low efficiency and at least 50% performance loss.	Medium Cannot exceed the performance of a mobile phone.	High CPH is based on Arm servers and offers various performance and storage specifications. It is far more powerful than physical mobile phones.
Compatibility	Poor Complex x86 instructions are not converted into simplified Arm instructions in one-to-one mode, causing severe application compatibility issues. These issues persist for a long time and are difficult to resolve.	High Same as mobile phones, ensuring application compatibility.	High High compatibility of Arm-based native applications
Stability	Medium The stability is hard to ensure because it is implemented based on various external open-source or non-commercial simulator software.	Extremely poor A large number of second-hand mobile phones are non-server products. In addition, manual soldering points and complex cable connections cannot ensure product quality and stability.	High In-house high-performance Arm chips and Arm servers have been widely used in the market, providing high stability and reliability.
Availability	High x86 servers and emulator software are used to build the system, which has low requirements and high resource availability.	Extremely poor It is very difficult to obtain sufficient and stable sources of mobile phones. The second-hand mobile phone market is changing rapidly, and the availability of the target mobile phones in the market is extremely poor.	High The product is provided as a public cloud service, which features large volume, flexible usage, and high elasticity of resources. The resources can be charged by month.
Simulation	Poor Based on the software upper-layer technology, although many mobile phone parameters can be modified, the features are obvious, and the x86 emulator is easily detected by the upper-layer application as a simulator.	High Exactly mobile phone used.	High Fully simulate mobile phones. If the cost-effective AOSP mode is used, underlying hardware data can be simulated for applications.
Specifications Flexibility	High Specifications can be set flexibly.	Poor Devices are purchased based on the set specifications, which are not flexible.	High The specifications can be flexibly set and adjusted, and high-specification overcommitment instances can be easily implemented.
