A network storage method, a switch device, and a controller are provided. The method is applicable to a controller based on OpenFlow protocol. The method includes: determining, by the controller, that a first switching equipment is to cache data requested by a first data packet; and notifying, by the controller, the first switching equipment to cache the data requested by the first data packet, and notifying the first switching equipment to establish a first flow table entry according to issued match information corresponding to the first data packet and issued action instruction information corresponding to the first data packet, wherein the action instruction information corresponding to the first data packet is adapted to instruct the first switching equipment to forward the data cached in the first switching equipment and requested by the first data packet.

A reception unit receives from a wireless relay device, a handover response indicating possibility of degradation in communication quality during wireless communication with the wireless relay device. A search unit searches whether or not a wireless relay device to which handover can be performed is present other than the wireless relay device. When the wireless relay device to which handover can be performed other than the wireless relay device is present as a result of search by the search unit, a transmission unit transmits a handover request to the wireless relay device found by the search unit.

This invention provides a method, system and apparatus for controlling mobility on a wireless network, which includes retrieving a network mobility preference, the network mobility preference indicating a level of mobility service for the mobile station, the level of mobility service indicating the extent to which the mobile station can handoff among base stations of the wireless network, and establishing a level of mobility service for the mobile station based on the retrieved network mobility preference. The method and apparatus may further include determining the level of mobility service for the mobile station to be fully or partially restricted based on the mobility preference.

Aspects relate to methods and apparatus for dedicated bearer (DB) establishment handling during call setup for long term evolution. According to aspects, a method is provided herein for wireless communications that may be performed, for example, by a user equipment (UE). The method generally includes establishing a connection with a first access point (AP) to perform a call set up procedure for a call; receiving from the first AP a message associated with handover to a second AP; delaying giving up the call setup procedure for a duration if the message includes or is associated with an indication to release a dedicated bearer; and allowing establishment of a DB with the second AP during the duration. Consequently, the DB can be established with the second AP, without the UE giving up the call setup, and the call can be performed, thus improving user experience. Numerous other aspects are provided.

A communication system according to an exemplary embodiment of the invention includes an MME (25) that, by movement of a UE (45), performs Tracking Area Update processing that changes a location registration area of the UE (45) and manages the location registration area of the UE (45) before change, and a PGW (75) that sends, to the MME (25), a control signal required to be notified to the UE (45) during execution of the Tracking Area Update processing. When the MME (25) receives the control signal, it sends a response signal indicating that the Tracking Area Update processing is being executed to the PGW (75), and, after completion of the Tracking Area Update processing, the PGW (75) sends the control signal to an MME (35) that manages the location registration area of the UE (45) after change.

There is disclosed a method, and a corresponding apparatus, for maintaining the settings of a user equipment, comprising: monitoring at least one stored setting in the terminal; responsive to a change in said at least one stored setting notifying a controller; and responsive to said notification selectively resetting said at least one stored setting.

A wireless, multi-modal access device and system adapted to integrate a number of communications networks operating in differing communication modes to facilitate transfer of communication links during a communication session to promote efficient use of the communication networks. The system includes a plurality of Universal Multi-Modal Access Devices UMMAD that are capable of operating at different frequencies and different protocols (TDMA, AMPS, CDMA, GSM, PCS etc) to communicate with any one of a number of Wide Bandwidth Gateways (WBG), which are each capable of communication using one or more of the protocols. The communication links may be switched from one WBG to another or from one protocol to another during a communication session to continue the session under the control of a Universal System Traffic Controller. Numerous other applications of the UMMADs for unique identification and e-commerce are disclosed.

A method for improved communication between network nodes of a mobile communication network includes: establishing a communication interface between first and second base station entities by generating a first instance of the communication interface at the first base station entity and generating a second instance of the communication interface at the second base station; transmitting, from a removal initiating base station entity, a first removal message to a removal responding base station entity, wherein the removal initiating base station entity is one of the first and second base station entities and the removal responding base station entity is the other of the first and second base station entities; receiving, at the removal initiating base station entity, a second removal message from the removal responding base station entity; and disabling the communication interface, wherein disabling the communication interface comprises removing the first and second instances of the communication interface.

Provided are a communication method and an apparatus for a multimedia broadcast multicast service (MBMS) in a wireless communication system. A wireless device determines, from among a plurality of subframes, a shared multimedia broadcast multicast service single frequency network (MBSFN) subframe utilized in a plurality of MBSFN regions, and receives a shared MBSFN reference signal (RS) from within the shared MBSFN subframe.

The invention provides a method for a user equipment, UE, operating in an orthogonal frequency division multiplexed, OFDM, communication system to signal that it is capable of operating at a radio bandwidth other than one predefined according to an OFDM communication standard for the system, the method comprising: the UE sending a capability information message to a base station, the message including an information field which indicates whether the UE supports flexible bandwidth operation or not, wherein the flexible bandwidth operation is at least one of an increase and a decrease in a number of subcarriers to be used by the UE within a frequency band being used concurrently for communication with the base station by other UEs over the bandwidth defined according to the OFDM communication standard.
