A mobile station including: a communication unit that includes a first logical processing subject and a second logical processing subject that operates in association with the first logical processing subject and performs multiple communications with a first wireless communication apparatus and a second wireless communication apparatus; an accumulation unit that accumulates data received from the second wireless communication apparatus; and a notifying unit that notifies the first wireless communication apparatus of data receiving status in the accumulation unit.

Described herein are systems and methods for optimizing buffering of streamed content based on upcoming coverage. For example, during a trip, the bit rate for transmission and receipt of streamed content can be dynamically adjusted based on the upcoming coverage such that when the upcoming network coverage is limited, the bit rate of the streamed content can be increased to ensure the buffer is sufficiently large to allow the user to experience (or appear to experience) uninterrupted streaming during the limited network connectivity. The bit rate can be calculated based on calculating a buffer size that can provide content at the play rate for the duration that the device is in a minimal or no network coverage area.

Systems, methods, and devices are provided to: perform packet data convergence protocol (PDCP) deciphering of the packets to store deciphered packets in a common buffer; perform PDCP reordering of the deciphered packets in the common buffer to generated a stream or reordered packets; perform robust header compression (ROHC) decompression on the stream of reordered packets; and determine, based on a packet indication, to reset the ROHC decompression, wherein the packet indication comprises a single bit in a PDCP header set to indicate a start of ROHC reset based on a path switch during a handover from a source cell to a target cell.

Disclosed in the present disclosure is a method for realizing continued transmission of user data when a user station crosses multiple wireless network cells. The method includes: constructing a continuation guide table in an access point (AP) of a wireless network cell; when a user station crosses a first cell to a second cell, configuring the continuation guide tables in the AP of the first cell and the AP of the second cell; based on the continuation guide tables, building a data link of a network layer between an correspondent station of the user station and the user station located in a terminal cell; continuously transmitting data between the correspondent station of the user station and the user station in a source cell along the data link after the user station accesses the terminal cell. Further disclosed in the present disclosure is an access point device of a wireless network cell. According to the present disclosure, uninterrupted transmission of data streams can be realized for data being transmitted during a complex condition that a user station crosses a plurality of wireless network cells, thereby improving the user experience when a user surfs the internet using a wireless network.

The present disclosure discloses a method and apparatus for processing information. The method for processing information comprises: retrieving, by a first base station, user context information of a User Equipment (UE) from a second base station by initiating a procedure to the second base station for retrieving the user context information, wherein the user context information doesn't include user history information; updating, by the first base station, bearer path information and resuming the user context information by initiating a path switch request message to a device in a core network; and performing, by the first base station, one or more of the following operations after the UE resumes to a connected state: re-starting to collect user history information, and re-retrieving user history information from the UE through an air interface.

The present disclosure provides a data transmission method, a terminal, and a network node. The data transmission method includes: performing a first operation in a case that an uplink transmission path of the terminal in a dual-connection mobility management process changes; where the performing a first operation includes either continuing data transmission of a source connection or stopping the data transmission of the source connection.

This application provides a data transmission method and device. In a process in which a terminal device is handed over from a source access network device to a target access network device, the source access network device processes buffered packet data convergence protocol (PDCP) data, so that when a forwarding tunnel is a tunnel of a session granularity or a group granularity, the target access network device accurately forwards data in the handover process. The method includes: encapsulating, by a source access network device, indication information in an encapsulation header of PDCP data, where the indication information is used to indicate a radio bearer used for sending the PDCP data by a target access network device; and sending, by the source access network device to the target access network device, the PDCP data in which the indication information is encapsulated.

A data transmission method and a related device and system to improve data transmission efficiency are described. In at least some embodiments, a first message sent by a second base station is received by a first base station. The first message is used to indicate that the second base station needs to transmit data. A second message is sent to the second base station by the first base station. The second message carries at least one address, and the address is associated with the data.

A bearer management device that performs control to reliably receive an incoming packet call that is made while a mobile terminal device is moving is provided. A bearer management device (10) includes an incoming call control unit (11) that, in the case where a mobility management device (30) manages a location of a mobile terminal device (40) as a result of movement of the mobile terminal device (40) whose location has been managed by a mobility management device (20), suspends processing of an incoming call to the mobile terminal device (40) made during movement of the mobile terminal device (40) until receiving a notification about completion of movement of the mobile terminal device (40) from the mobility management device (30), and resumes incoming call processing to the mobile terminal device (40) after receiving a notification about completion of movement of the mobile terminal device (40) from the mobility management device (30).
