A base station distributes C-RNTI method comprising steps: the user equipment sends the random access leader sequence to the base station; the base station sends the response message to the random access leader sequence to the user equipment, the message comprises: a distributing information of the uplink resource, a time regulating information, and an information together with the random access leader sequence identification number indicating CRNTI. The user equipment will send L3 message to the network end; the network end will send response of the L3 message to the user equipment. The present invention uses the random access leader sequence and sending sub-frame used by the user equipment and detected by the base station comparing with the traditional C-RNTI distributing method. The present invention sends the random access channel information to packet C-RNTI, thereby decreasing the indicating information bit needed by the C-RNTI distribution, decreasing the signaling burden needed by the C-RNTI distribution, optimizing the random access course, promoting the performance of the random access.

The invention provides a determination method of a pseudo base station and a mobile terminal. The method comprises the steps of sending a base station parameter acquiring request to a base station of the local community through the mobile terminal; receiving the base station parameters from the base station through the mobile terminal; comparing the base station parameters with the preset base station parameters of an operator; if the base station parameters are the same as the base station parameters of the operator, acquiring electric signal strength of the base station; comparing the variable of the electric signal strength of the base station within the preset time quantum with the preset strength variation value; if the variable of the electric signal strength of the base station within the preset time quantum is less than the preset strength variation value, comparing the electric signal strength of the base station with the preset electric signal strength; if the electric signal strength of the base station is more than the preset electric signal strength, determining that the base station is the pseudo base station. With the adoption of the determination method of the pseudo base station and the mobile terminal, the pseudo base station can be quickly and conveniently recognized, and meanwhile, the signaling load of the base station can be reduced; the privacy can be prevented from disclosing; in addition, the pseudo base station can be timely positioned.

A method and device for obtaining position information of a target terminal are discussed. According to an embodiment, the method includes sending a start message to a home network, the start message used for positioning of the target terminal; receiving a response message from the home network, the response message containing address information of a visited network; sending a positioning initiation message to the visited network using the address information in the response message; and performing a positioning procedure with the visited network, wherein the positioning procedure is performed without connection with the home location server.

The invention discloses a pseudo base station positioning method based on RSSI base station signal estimation. The pseudo base station positioning method comprises the following steps: extracting base station information obtained by at least three pieces of UE at the same moment by a central server, retrieving all values in a signal transmission strength value section at a preset step length delta RSSI to serve as a RSSI estimated value sequence, and calculating estimation distances of UE and a pseudo base station corresponding to the estimated values according to a signal transmission loss model; and using the RSSI estimated value corresponding to a value having the maximum fitting degree as an optimal estimation of signal transmission strength of the pseudo base station, and using the gravity center of a fitting triangle corresponding to the optimal estimation as a positioning estimation of the pseudo base station. The pseudo base station positioning method disclosed by the invention can be used for positioning the pseudo base station in a quick, convenient and low-cost manner, only the UE and the central server are needed to position the pseudo base station, the bottleneck in traditional pseudo base station positioning that special high-end equipment and onsite searching and positioning are necessary is broken through, and dynamic local positioning of the pseudo base station can be achieved to play important significance in fighting against illegal and criminal activities of the pseudo base station and maintaining the security of information society.

A method for transmitting control signaling of data transmission reinforcement correlation in mobile communication system includes realizing time and rate dispatch by utilizing absolute power command configuration and coding efficiency command configuration. It features that load of down link physical layer control signaling can be much reduced since only transmission power command configuration and coding efficiency command configuration are required in down link signaling with no transmission of transmitting format combination set command configuration and transmitting initial time as well as transmitting time internal.

This invention discloses a random access method of cellular wireless communication system, including a second layer and a third layer of a terminal initiates a physical layer to send a random access preamble; the second and third layers judge whether a random access response is received in a receiving time window; if the second and third layers judge that the random access response is not received, then the physical layer is initiated so as to re-send the random access preamble. Judging whether the random access response is received in the receiving time window and determining whether re-sending the random access preamble are finished by a high layer protocol through this invention, which improves the efficiency of protocol processing and reduces the complexity of physical layer processing, and further reduces the parameter transferring between the physical layer and the high layer and the signaling load of the information transferring.

A method, a terminal, and a system for establishing a Push to Talk Over Cellular (PoC) group session in a PoC network based on session initiation information, such as information regarding presence of clients to be invited or session start-up time. According to the method, Universal Resource Indicator (URI) information regarding invitation and Information Reservation Service (IRS) parameters are set up in a PoC eXtensible markup language Document Management Server (XDMS), and a PoC server is requested to provide an IRS so that a session is established.

The embodiment of the invention provides a hybrid automatic repeat request information transmission method and device. A corresponding relationship between time domain resource information and frequency domain resource information of a PSFCH and a PSSCH is established by using a pre-configured PSFCH resource pool, and the PSFCH is indicated through the time frequency resource information of the PSSCH, which is a completely implicit indication mode. According to the invention, resource conflicts can be avoided, signaling burden is low, time delay is reduced, and resources are saved.
