A session controller provides mobility management support in a 1xEVDO wireless communication network, such as one configured in accordance with the TIA / EIA / IS-856 standard. Operating as a logical network entity, the SC maintains location (e.g., a pointing tag) and session information at an access network controller (ANC) granularity, thus allowing it to track access terminal (AT) transfer between ANCs but within subnet boundaries, where a network subnet comprises one or more ANCs. This allows a packet control function (PCF) to maintain location information at a packet zone granularity, thereby reducing mobility management overhead at the PCF. The SC provides updated tag and session information to PCFs, ANCs, and other SCs as needed. Information exchange with other SCs arises, for example, when two or more SCs cooperate to maintain or transfer routing and session information across subnets.

The present invention provides a method and architecture on how mobile stations (MS 132) are provisioned about information of an unlicensed mobile access (UMA) network controller (UNC 142). The UNC (142) in accordance with the present invention provides three different logical roles (i.e., provisioning (300), default (302) and serving (304)). More specifically, the present invention provides a method for assigning a mobile station (MS 132) to an unlicensed mobile access (UMA) network controller (UNC 142) in an unlicensed mobile access network (UMAN 102). The MS (132) is connected to a provisioning UNC (402) and discovers a default UNC (404). A serving UNC (406) is then determined to assign the MS (132) to and the MS (132) is assigned to the serving UNC (408). The serving UNC (620) can be the default UNC (612), the provisioning UNC (604) or another UNC.

A synchronization apparatus and method in a mobile communication system. The apparatus and method include measuring transmission delay time by a Packet Control Function (PCF) or an Access Network Controller (ANC) by exchanging packets with each ANTS, and selecting via the PCF or the ANC the longest transmission delay time of the measured time as an initial wireless transmission time, transmitting by the PCF or the ANC the wireless transmission time of the packet to said each ANTS together with packets, calculating a packet waiting time, which is a difference between the time at which said each ANTS has received the packets and the time at which the corresponding packets has been actually transmitted wirelessly, and reporting the calculated packet waiting time to the PCF or the ANC, and updating via the PCF or the ANC the wireless transmission time of next packets by means of information for the packet waiting time from each ANTS, and transmitting via the PCF or the ANC the updated wireless transmission time to the ANTSs.

A method and system for handover of a mobile station (MS) to an unlicensed mobile access network controller (UNC) in an unlicensed mobile access network (UMAN). In one embodiment, the MS sends an unlicensed mobile access (UMA) radio resource (URR) Registration Request message to the UNC with one or more location identifiers for the MS. The location identifiers may include a GSM Cell Global Identity, an access point (AP) Radio Identity, a set of GPS coordinates, or an AP location. The UNC selects absolute radio frequency channel numbers (ARFCN) and base station identity codes (BSIC) values from a table based on the location identifiers and returns them to the MS in a URR Registration Accept message.

In cellular mobile networks handover between base stations of adjacent cells requires the identity, address and frequency of all adjacent cells to be known to other elements of the network. Conventional networks (e.g.cellular networks) can be extended by the addition of unlicensed-radio access networks. Said unlicensed networks can include an access network controller preferably connected via a broadband network to a plurality of low-power local base stations, which communicate with mobile stations over an unlicensed radio interface. The number and changing location of the local base station renders the operation and maintenance required to enable handover from the conventional network to these access networks prohibitively complex. This difficulty is alleviated by assigning to all the mini-cells of the unlicensed network a single identifier being said single identifier associated to the access network controller. With this arrangement regardless of which base station mini-cell an active call is being handed-over to, the conventional network will be able to route the request to the access network controller.

An Unlicensed Mobile Access Network Controller (UNC) and method for providing an early indication of service failure to a mobile station registered with the UNC. When the UNC detects a network failure that prevents service to the mobile station, the UNC prohibits new registrations by other mobile stations, starts a timer, and monitors the network failure to determine if the failure clears. If the failure clears before the timer expires, new registrations are accepted from other mobile stations. However, if the timer expires before the failure clears, the UNC continues to prohibit new registrations from other mobile stations, and deregisters the mobile station when a network Keep Alive timer expires for the mobile station. When a plurality of mobile stations are registered with the UNC, the UNC deregisters the plurality of mobile stations one at a time as the network Keep Alive timer expires for each mobile station.
