Embodiments of the present invention disclose a data transmission method, a mobility management entity, and a mobile terminal. The method includes: receiving, by a mobility management entity, a small data transmission parameter that is sent by a home subscriber server HSS or a user equipment, where the small data transmission parameter includes an indication of whether the user equipment supports small data transmission; determining, by the mobility management entity, a small data transmission policy according to the small data transmission parameter; sending, by the mobility management entity, the determined small data transmission policy to the user equipment; and performing, by the mobility management entity, the small data transmission with the user equipment according to the small data transmission policy. The present invention proposes a relatively complete small data transmission solution, thereby implementing effective transmission of small data.

An evolved Node B (eNB) and method for coherent coordinated multipoint transmission with per CSI-RS feedback are generally described herein. The eNB may configure a first cooperating point and a second cooperating point to jointly transmit a multi-node channel-state information (CSI) reference signal (RS) (CSI-RS) in predetermined resource elements of a resource block. The eNB may receive CSI reports as feedback from user equipment (UE). The CSI reports may include a precoding matrix indicator (PMI) indicating relative phase information between the cooperating points based on the multi-node CSI-RS. The CSI reports for the multi-node CSI-RS may be restricted to a PMI of rank-1. The eNB may configure the cooperating points for a coherent joint transmission to the UE based at least on the relative phase information. The coherent joint transmission may also be jointly beamformed based on single-node PMIs.

Radio resources can be allocated in a manner avoiding a zero power problem by selecting one of two reference signals for control channel estimation, and transmitting the selected reference signal in a resource block (RB) or RB pair carrying the control channel. The two reference signals span common resource elements (REs) in the RB or RB pair. Alternatively, a zero power problem can be avoided by assigning modified WALSH codes to the two reference signals, and transmitting the two reference signals in the RB or RB pair carrying the control channel in accordance with their modified WALSH codes. The modified WALSH codes include complex constants having a non-zero phase difference with one another. A control channel can be evenly partitioned in accordance with a checkerboard partitioning technique.

[PROBLEM TO BE SOLVED] To achieve roaming connection in which a communication charge is suppressed inside and outside a country. [SOLUTION] The portable telephone includes a communication section 10 that is used for communication inside and outside a country. When power is applied to the portable telephone, an acquisition means 11 acquires information on a communications company that can be connected at the time of connection to a base station. A judgment means 12 judges whether or not the acquired information on the communications company indicates a communications company for which flat-rate data communication can be performed. In addition, a connection control means 13 performs connection, by the communication section 10, to the communications company that is indicated by the acquired information on the communications company and sets that data communication can be performed when it is judged that the information on the communications company indicates the communications company for which flat-rate data communication can be performed. On the other hand, the connection control means 13 performs connection, by the communication section 10, to the communications company that is indicated by the acquired communications company information and sets that data communication is not allowed to be performed when it is judged that the information on the communications company does not indicate the communications company for which flat-rate data communication can be performed.

Embodiments of the present invention provide a communication method and system, an access network device, and an application server. The communication method includes: receiving, by an access network device, a service packet; and sending, by the access network device, the received service packet to an application server according to a policy, where the application server is arranged at an access network side, and is independent from the access network device or in the access network device, and the application server supports operation of at least one service. It can be seen that, an application server that supports operation of third-party applications is introduced at an access network side, so that a UE can directly perform service interaction with the access network side, which significantly improves the response time of a user request, decreases service delay, and improves the QoS of a service, thereby improving user experience.
