A signal amplifying device and methods for control a signal amplifying device and for identifying a signal amplifying device are provided. The device includes: a baseband module, a user identification module interface, return side RF modules and antennas, access side RF modules and antennas. The return side antenna receives a downlink signal, which is transmitted to a corresponding access side RF module and the baseband module. An uplink signal is received by the access side antenna, which is transmitted to a corresponding return side RF module and the baseband module. The baseband module is adapted to process the uplink/downlink signal, control synchronization of the return side RF module and the access side RF module and control turning on and off of the same, read a user information. Accordingly, a cellular network can control a micro-power repeater effectively, and further more functionality can be added and performance can be improved.

A demand paging method for a mobile terminal, a controller and a mobile terminal, wherein the demand paging method determines, when a mobile terminal needs to operate a compressed file, a storage location of the compressed file in an external part of the controller of the mobile terminal; a decoding unit of the internal part of the controller of the mobile terminal decompresses the compressed file in the storage location; the mobile terminal saves the decompressed file to a designated part of the memory, wherein the designated part of the memory comprises the memory in the internal part of the controller of the mobile terminal and/or the memory in the external part of the controller of the mobile terminal; the mobile terminal continues to operate on the basis of the decompressed file. The technical solution increases the processing efficiency of demand paging of the mobile terminal.

The present invention discloses a method and apparatus for controlling updates to a mobile device consisting of checking a ROM installation package and storing the check data, or encrypting a ROM installation package and storing said encrypted ROM installation package. The stored check data is used to check a ROM installation package or to decrypt a stored encrypted ROM installation package when updating a mobile device. If it is verified to be correct or to be decryptable, the verified or decrypted ROM installation package is installed. If it is verified to have errors or to be undecryptable, the installation of the ROM installation package is terminated. The present invention reduces the risks associated with the destruction or disclosure of data when mobile devices are lost.

Systems and methods for generating a Long Term Evolution network return procedure. A mobile terminal may generate, in absence of redirection instruction from a circuit-switched network, a Long Term Evolution network return procedure that, when instantiated by the mobile terminal, implements connection of the mobile terminal to a Long Term Evolution network based on measured signal strength of at least one Long Term Evolution network access point.

Systems and methods for generating a Long Term Evolution network return procedure. A mobile terminal may generate, in absence of redirection instruction from a circuit-switched network, a Long Term Evolution network return procedure that when instantiated by the mobile terminal implements connection of the mobile terminal to a Long Term Evolution network based on a ranking of measured Long Term Evolution network access points.

A method in a communication terminal for measuring one or more measurement quantities, wherein the measurement quantities correspond to a measurement identity, the method comprising: determining whether measurement of the measurement quantities can be performed in a first measurement occasion corresponding to the measurement identity; and if measurement of the measurement quantities cannot be performed in the first measurement occasion, measuring the measurement quantities using one or more other measurement occasions, wherein the one or more of the other measurement occasions correspond to at least one other measurement identity.

A method for assigning signature sequences for E-HICH channel which may avoid the unbalanced situation brought about by the codeword assignment is provided, wherein the use of User Equipment (UE) signature sequences on Enhanced Dedicated Channel Hybrid Automatic Repeat Request Acknowledgement Indicator Channel (E-HICH) is equalized, so as to drive the average detection performance toward equity for different UEs to detect their respective signature sequences on E-HICH channel, and to reduce the average false detection rate for the respective UE on the feedback information transmitted thereto. The method includes: firstly, assigning a E-HICH logical signature sequence index r for each UE; then, converting the logical signature sequence index r into a physical signature sequence index r' varying with time by using a random permutation function; and after that, assigning a signature sequence corresponding to the physical signature sequence index r&#x2032; to the respective UE.
