Abstract: A network infrastructure for a wireless communication system is disclosed. The infrastructure comprises a fronthaul network, an RRH pool, a radio service chain (RSC). The RSC is coupled to the fronthaul network and the RRH pool for allocating the RRH resources. The RSC comprises an orchestrator and a remote radio head (RRH) controller. The orchestrator is used for receiving a radio resource request from the at least one C-RAN and converting the radio resource request into a RRH specific command. The RRH controller is used for slicing the RRH resources to create virtual RRHs according to the radio resource request.

Abstract: A playback system for a video conferencing record includes a first electronic device obtaining a video conferencing record and a second electronic device receiving the video conferencing record. The second electronic device analyzes the video conferencing record into a plurality of chunks based on recognizing each dialog in the video conferencing record, analyzing the topic intensity of each dialog, and analyzes the relevance of each chunk to move it out of a dialog or add it to another. Video clips from the video conferencing record can be retrieved according to a keyword index, and the video clips accordingly displayed on a display. A playback method for such video conferencing record or the parts is also provided.

Abstract: An application collaboration (AC) platform is used to realize application collaboration between two user devices. The AC platform includes a semantic database which stores semantic descriptions of a plurality of user devices. When a semantic query message is received from a request devices, one or more of the user devices which match the semantic query message are searched and one of the searched user devices is selected as a target device. Data for application collaboration is exchanged between the request device and the target device. The target device performs the application collaboration according to the data and generates result data after performing the application collaboration. The result data is transmitted to the request device to accomplish the application collaboration between the request device and the target device.

Abstract: A customer premise equipment (CPE) capable of translating between different internet protocol (IP) address versions connects at least one local device to a network. A table is created for recording dual stack devices which support both IPv4 and IPv6 address versions. When a local device which is not recorded as a dual stack device in the table requests access to a remote device, an IP address of the remote device is analyzed. If the IP address of the remote device is determined to be not compatible with the IP address of the local device, a version of the IP address of the remote device is translated to be same as a version of the IP address of the local device, to enable communication between the local device and the remote device.

Abstract: A computing device and method for searching for parameters in a data model uses a first hash table to store index values of all parameter names in a data model, and uses a second hash table to store index values of data paths of duplicate parameters names in the data model, and changes the comparison sequence when searching for parameters in the data model. That is, comparing beginning from the last character in the input data string, if a leaf node in the data model matches the last character, then comparing parent nodes of the leaf node with the remaining characters of the input data string. Then, a data path of a parameter having a unique name is located according to the first hash table. Furthermore, data paths of parameters having duplicate names is located according to the second hash table.

Abstract: A cloud storage access device includes a data fetching unit, a user management unit, and a data link unit. The data fetching unit collects private data of each user of the cloud storage access device. The user management unit creates a home directory corresponding to each user in the cloud storage access device. The data link unit connects each of the home directories to both the cloud and a local storage of a network terminal, such that the cloud storage access device communicates with both the cloud and the local storage. Each user of the cloud storage access device stores data to the cloud or the local storage and accesses data stored in the cloud or the local storage through the home directory corresponding to the user.

Abstract: A network unit and method for executing a function of a network termination unit include computing hash values corresponding to configuration parameters, confirming function pointers of functions corresponding to the configuration parameters, and inserting the hash values and the function pointers into a hash table. The network unit and method further include computing a hash value of a configuration parameter name acquired from a configuration command, confirming a function pointer corresponding to the hash value if the hash table includes the hash value, and executing a function corresponding to the function pointer.
