摘要： A method and system is provided for providing packet data service and circuit switch service during the same session to a mobile station (MS) whose capabilities do not allow such services to be provided thereon by the wireless network according to the its specifications. First, a voice service is provided between the MS and a first client through a switch device, the voice service conforming to a predetermined communication protocol. The MS is then notified about an incoming data service request from a second client to transfer a predetermined amount of data. The voice service is disconnected between the switch device and the MS if the user decides to activate the incoming data service. The voice service between the switch device and the first client is still maintained. The data service from the second client to the MS through the switch device is then established. The data service between the switch device and the MS is disconnected while the data service between the switch and the second client is maintained after the predetermined amount of data has been transferred from the second client to the MS. The voice service between the switch and the MS is re-established if needed. Also, the same client can initiate the voice and packet data service request to the same MS.

摘要： Geographical redundancy and an efficient switchover process to redundant equipment (210) is achieved by separating active main equipment (220) and standby redundant equipment in different geographical locations so that failures can be avoided in the event of a natural disaster or other event that affects an entire building or region. In addition, partial switchover can be performed for components or functions that become inoperative to corresponding redundant components in the standby equipment. To provide further redundancy and prevent unneeded switchovers, status or heartbeat messages are transmitted between the active main equipment and standby redundant equipment over two different networks.

摘要： The present invention provides a system and method for migrating a control of a wireless communication service provided to a mobile station (MS) in a first network depending on a first technology to a second network depending on a second technology. When receiving a request for the wireless communication service in the first network by a mobile switch center (MSC), at least one instruction is obtained to grant or deny the wireless communication service from a first control device in the second network, the first control device providing the instruction based on its communication to a management subsystem for the control of the wireless communication service. If the wireless communication service is granted, a second control device in the first network controlled by the first control device allows the MS to execute the wireless communication service with a receiver. If the wireless communication service is denied, the second control device in the first network controlled by the first control device prohibits the MS to execute the wireless communication service with the receiver, wherein the first and second control device communicate with each other using a predetermined protocol independent of the network technology used by either the first and the second network, and wherein the first network thus maintains the control of the wireless communication service through the management subsystem connected to the second network without implementing additional management subsystem.

摘要： A method for evenly partitioning a cellular telephone system into a plurality of sets. The method partitions subsets of a cellular telephone system, such as cells, into a plurality of sets, such as mobile switching centers. The method first models each cell as a node having a node weight representing real time operating cost of the cell and a node edge weight representing call handoffs to and from the cell. The method similarly models each set having a set weight and set edge weight, which are similar to the node weight and node edge weight. Once modeled, the nodes are initially distributed into the sets so that each set has approximately the same set weight. Then a slack node is provided to each set. The slack node allows all the sets to have the exact same set weight and also accommodates for variability in set edge weights. Once the slack nodes are in place, several binary split operations are performed on the nodes. For each binary split operation, two nodes are temporarily swapped and a gain is determined. Eventually all the nodes will have been swapped and a maximum gain can thereby be deduced. A determination is made as to which nodes were swapped to achieve the maximum gain and those nodes are then permanently swapped.
摘要翻译：一种用于将蜂窝电话系统均匀地划分成多组的方法。该方法将诸如小区的蜂窝电话系统的子集分成多个集合，诸如移动交换中心。该方法首先将每个小区建模为具有表示小区的实时运营成本的节点权重的节点和表示去往和来自小区的呼叫切换的节点边缘权重。该方法类似地对具有设置权重和设置边缘权重的每个集合进行建模，其类似于节点权重和节点边缘权重。一旦建模，节点最初分布到集合中，使得每个集合具有大致相同的集合权重。然后向每组提供松弛节点。松弛节点允许所有组具有完全相同的设定权重，并且还适应设置边权重的变化。一旦松弛节点就位，在节点上执行几个二进制拆分操作。对于每个二进制拆分操作，暂时交换两个节点并确定增益。最终所有节点都将被交换，从而可以推断出最大增益。确定哪些节点被交换以实现最大增益，然后这些节点被永久地交换。

摘要： In a cellular mobile access communications system each mobile terminal registers its location at intervals. From the registration history of each mobile, a probable group of cells within which a mobile terminal may be located is predicted. When a mobile is to be paged, the paging message is transmitted to the predicted cell group. If no response is received from the terminal, the page message is then broadcast to further system cells. This reduces the overall paging load on the system.

摘要： The foregoing objects are achieved as is now described. Provided are a method and system for utilization with wireless communications systems having a cellular architecture covering a geographic area. The method and system accomplish their objects via the following. The geographic area is defined. One or more pairs of the sectors within the defined geographic area wherein a weak connection zone exists are determined. The geographic area is decomposed into two or more sub-areas wherein each sub-area is isolated from other sub-areas by the determined one or more pairs of sectors having a weak connection zone. A first of the sub-areas is selected. Frequency groups are assigned to each sector within the first selected sub-area such that signal to noise ratio is optimized. Thereafter, a second of the sub-areas is selected. One or more sectors within the second selected one of the sub-areas which are linked to sectors within the first selected sub-area are selected. Frequency groups are assigned to the selected sectors within the selected second of the sub-areas such that signal to noise ratio in the selected sector within the selected second of the sub-areas is optimized. Thereafter, frequency groups are assigned to every other sector within the selected second of the sub-areas such that signal to noise ratio is optimized across the second selected sub-area and such that signal to noise ratio over the defined geographic area is optimized.
