A wireless communication method and system are provided. A first wireless communication numerology, e.g., OFDM operating parameters, corresponding to a first operational mode is established. A second wireless communication numerology corresponding to a second operational mode is also established. The first wireless communication numerology is different than the second wireless communication numerology. One of the first operational mode and the second operational mode is selected. One of the first wireless communication numerology and the second wireless communication numerology corresponding to the selected operational mode is used in which communication in the first operational mode and the second operational mode use substantially similar synchronization channels. The present invention also uses the same superframe structure for the first and second operational modes for Ultra-Mobile Broadband (“UMB”) networks and the same frame structure for the first and second operational modes for Long Term Evolution (“LTE”) networks.

A method and apparatus configure Femto Devices in an Ultra Mobile Broadband network system. A Femto Device transmits a Femto pilot signal to an Access Terminal, which is served by a plurality of base stations in the Ultra Mobile Broadband network system. The Access Terminal then transmits to the Femto Device an identifier of a base station that controls a macro cell where the Femto Device is located. Next, a Neighbor Discovery Request message is transmitted from the Femto Device to the base station in dependence upon the received identifier of the base station. In response to the Neighbor Discovery Request message received, a Neighbor Discovery Report message is transmitted from the base station to the Femto device. The Neighbor Discovery Report message includes a field indicating network addresses of a Session Reference Network Controller and an Access Gateway that connect to the base station. Finally, the Femto Device connects to the Session Reference Network Controller and the Access Gateway via the Femto device in dependence upon the network addresses of the Session Reference Network Controller and the Access Gateway.

The invention discloses a method for responding a request message of deleting characteristics in ultra mobile broadband (UMB) technology. The request message of deleting characteristics is sent to an access terminal by an access network through an air interface corresponding to the ultra mobile broadband technology; when one or a plurality of characteristics are required to delete by the access network, the access terminal sends a receiving message of deleting characteristics to the access network; the receiving message of deleting characteristics carries the following information that: message identification, truncation identification, characteristic counting and characteristic index, wherein, the characteristic counting information is determined by the access terminal according to the number of characteristics agreed to delete; the characteristic index information is one or a plurality of characteristics which are agreed to delete by the access terminal. Compared with the prior art, the method strengthens a characteristic management mechanism in a UMB system, saves the signaling interaction expenses of the air interface and the air interface resource.

The invention discloses a safety ability negotiation method in the ultra mobile broadband system which comprises that: 1) after a terminal AT receives an identity request message, the terminal AT triggers an authentication process and finishes the safety ability negotiation between the AT and an SRNC, between the AT and eBS through an HAAA, a group of encryption algorithm and integrity protectionalgorithm which are commonly supported are selected, and a selected algorithm identifier is assigned to the SRNC, the eBS and the AT; 2) according to the confirmed encryption algorithm and integrity protection algorithm as well as an encryption key and an integrity key which are produced during the key exchange , the AT and the eBS make integrity protection to a subsequent sent signaling message and encrypts a subsequent sent sensitive message, and a receiving party makes integrity check and encryption to the received messages. The invention can achieve the encryption algorithm and the integrity protection algorithm used between the terminal and the access network, and furthest maintains the integrity of the main content of the prior specification.

The invention discloses a shutdown registration processing flow in an ultra mobile broadband (UMB) access network. The processing flow comprises the following steps: S102. when a session reference network controller receives a shutdown registration message of an access terminal, the controller informs a data binding point of shutdown state and a shutdown registration reason of the access terminal; and S104. the data binding point informs an access gateway of the shutdown state and the shutdown registration reason of the access terminal. The flow ensures the shutdown registration message to beeffectively processed at the access gateway so as to ensure paging efficiency and the like of the access network, thus further improving the performance of the whole UMB system.

The invention discloses a processing method for ultra-mobile broadband characteristics. The processing method comprises the followings steps: S302, an actively concentrated access network of the access terminal determines whether to delete one or more characteristics and sends a request message for deleting the characteristics to a forward service access network; S304, under the circumstance thatthe forward service access network receives the requests for deleting the characteristics from the other actively concentrated members of the access terminal, or the forward service access network needs to initiate characteristic deletion, the forward service access network sends the message for deleting the characteristics to the access terminal; S306, the access terminal receives the request for deleting the characteristics and determines whether to delete one or more characteristics in a characteristic list, under the condition that the deletion is accepted, the acceptation message for deleting the characteristics is sent to a reverse service access network; S308, after receiving the acceptation message for deleting the characteristics, the reverse service access network sends the acceptation message for deleting the characteristics to all the actively concentrated access networks of the access terminal to inform the access networks to delete the corresponding characteristics; and simultaneously, after receiving the notification message for deleting the characteristics, the actively concentrated access network deletes the corresponding characteristics. Meanwhile, the invention also comprises a processing mechanism that the access terminal refuses to delete the characteristics.
