The present disclosure provides a method for accessing a cell and a device for accessing a cell. The method for accessing a cell includes: receiving, by a terminal device, system information sent by a serving cell where the terminal device resides, wherein the system information comprises a cell resident risk identifier and measurement information; determining, based on the cell resident risk identifier, that the serving cell has a risk to be subjected to a lakeside effect, and detecting signal quality of the serving cell based on the measurement information; and determining whether the terminal device is subjected to the lakeside effect based on the detected signal quality, and accessing the serving cell when it is determined that the terminal device is not subjected to the lakeside effect. According to the method for accessing a cell, the terminal device determines, before accessing the serving cell, whether the terminal device is subjected to the lakeside effect, such that the terminal device within the coverage area of the serving cell accesses the base device successfully while the terminal device outside the coverage area of the serving cell which resides at the serving cell may be detected and prevented in time to access the serving cell, thereby to avoid the failure accessing to the base device of the terminal device caused by the lakeside effect.


The present disclosure provides a communication method, a communication system, a resource pool management system, a switch device and a control device in a Software-Defined Network (SDN). The communication method may include steps of: obtaining network attributes of one or more virtual machines which are configured by a resource pool management system based on operations on a network resource pool by a user; converting tenant networking topology information derived from the network attributes into flow tables, in the case that a first virtual machine and a second virtual machine attempt to communicate with each other for the first time; and distributing the flow tables to one or more switch devices corresponding to the one or more virtual machines, so as to directly discard packets to be transmitted during the communication for the first time and subsequent communication between the first virtual machine and the second virtual machine, in response to determining by one of the switch devices that the communication between the first virtual machine and the second virtual machine is disabled based on a corresponding flow table. In the communication method, it is not necessary for the controller to broadcast the ARP messages to the whole SDN, and it is reduced the number of the packet_in packets to be transmitted to the SDN controller, so that the network resources of the SDN may be fully utilized, and the availability of the network resources and the controller resources are improved.

This project will develop multi-antenna full-duplex technology to achieve highly efficient spectrum usage in HetNets (heterogeneous networks). Full-duplex radios are much more than just doubling the capacity as perceived in current literature. More explicitly speaking, we believe that it is making communication technologies impossible become possible. The implications of full-duplex communications are transformative. Full duplex, which permits simultaneous transmission and reception, motivates a fundamental rethinking of the ways wireless networks are designed and optimised. However, the fact that the power of the transmitting signal is so much larger (over 100 dB) than that of the receiving signal has fuelled the belief that it is impossible to separate them on a single channel. Recently, this picture has begun to change, following the pioneering work by Choi et al. from Stanford University who demonstrated a working full-duplex radio on a single channel. We envisage that full-duplexing can transform the operations of wireless networks and is expected to have massive benefits in HetNets. HetNets are widely regarded as one key wireless technology for the provision of future wireless communications (including 5G) by complex interoperation between macrocells and small cells. The enormous interest for HetNets is due to their capability of providing high regional capacities and flexible coverage, and more importantly their low infrastructure costs. In HetNets, a mosaic of wireless coverage is obtained by a variety of wireless coverage zones from macrocell to small cell such as, pico- and femtocell. Of increasing interest to mobile operators are the customers installed femtocells that can greatly improve indoor coverage but share the same frequency band as the macrocells. There is a huge scope of research in resource allocation and physical-layer design and optimisation in HetNets. This project will exploit the full potential of MIMO full-duplexing in HetNets by designing a holistic solution that interconnects antenna design, physical-layer signal processing, and network resource allocation to address the inherent challenges of full-duplexing and realise its massive end-to-end benefits. To achieve this goal, UPFRONT first proposes new antenna design specially for wideband MIMO full-duplexing, which is substantially more challenging than the existing narrowband single-antenna case. Next we leverage the powerful MIMO signal processing to handle the overlooked in-tercell interference and new interference introduced by the full-duplex operation, which are critical to deliver the end-to-end benefits of full-duplex HetNets but were not well studied before. Furthermore, UPFRONT will explore the unexplored full-duplexing opportunities to address the networking-wide resource allocation challenges associated with the adoption of full-duplexing small cells under the greater macrocell structure sharing the same mobile spectrum. The outcomes of UPFRONT will elucidate the importance of a holistic approach to full-duplexing design and have impact in fundamental and practical research of future wireless networks.


The present disclosure provides a TEE initialization method. An operator identifier acquired from an SIM card is compared with operator identifiers in a list or a table of correspondence between the operator identifiers and public keys preset in a TEE of a mobile terminal, so as to acquire a public key and authenticate a TSM platform with the public key. After the TSM platform has been authenticated successfully, loading processing on the TEE is completed, and a management key of the TEE is downloaded from the TSM platform. According to the present disclosure, it is able to initialize the TEE of the mobile terminal without designating an operator, thereby to improve the openness of the mobile terminal as well as the user experience.
