摘要： A wireless communication system includes a plurality of base stations, a plurality of base station controllers and a plurality of mobile switching centers. The plurality of base stations each support wireless communications within a respective cell and service load therein relating to subscribing units operating therein. Each of the base station controllers couples to a plurality of base stations and each of the mobile switching centers couples to at least one base station controller. The plurality of base station controllers and the plurality of mobile switching centers are managed to dynamically route load between the base station controllers and the mobile switching centers in an effort to equalize load on the plurality of mobile switching centers. At least one base station controller of the plurality of base station controllers may route its load to a first mobile switching center during a first period and route its load to the second mobile switching center during a second period. The first period and the second period may correspond to differing time periods and/or differing days. Such periods may be determined based upon historical loadings of the wireless communication system and simulation results. However, in other operations, the load is switched based upon actual system loading and the periods are determined according to the actual system loading. In other operations of the wireless communication system, a base station controller routes its load concurrently to both a first mobile switching center and a second mobile switching center of the plurality of mobile switching centers. In such operations, a first amount of load is routed to the first mobile switching center and a second amount of load routed to the second mobile switching center, such levels determined based upon loading of at least one of the first mobile switching center and the second mobile switching center.

摘要： A data processing system implements a load balancing methodology which recognizes the effects that multiple, mobile subscribers have within a wireless communications network. During execution of this load balancing methodology, a rehoming operation is executed at a telephone central office to move some subscribers in a network to a new home mobile switching center with a minimum number of rehoming steps. To perform this rehoming operation, a mobile switching center in a network which has a highest load is selected first. Mobile switching centers which have a load lower than a network average load are considered to be candidates for a rehome destination. All subscriber groups homed to the highest loaded mobile switching center are evaluated to determine whether or not a rehoming operation using this subscriber group would provide a highest benefit and give a lowest standard deviation of loads among mobile switching centers after the rehome operation is selected. This operation is iterative and searches for the best directory number to be homed in each candidate mobile switching center. A resulting balanced load of network resources will serve to increase the effectiveness and longevity of a current wireless communications network before additional equipment is required.

摘要： A method and system are disclosed for utilizing a session processor having multiple internal states to control communication sessions occurring within a wireless and satellite network that includes at least one control interface. First, a message is received from the control interface and is then processed. Next, an internal state of the session processor is changed such that a response message may be formulated. Thereafter, internal tables and counters are updated in response to the message. Finally, the response message is delivered to the control interface, such that the session processor may be utilized to maintain comprehensive and seamless control of communications sessions occurring within the wireless and satellite network.

摘要： A number of user IDs are assigned to each wireless device. The number of user IDs required is based on the type of information transmitted (e.g., video, voice, or data). The user ID's generate the orthogonal Walsh codes used to cover a data signal to be transmitted. Each Walsh code is 2n-bits in length and the memory size is 2n×2n where n is the number of bits in the Walsh code. Each unique user ID addresses a memory to generate a unique Walsh code corresponding only to that user ID. The orthogonal codes output from the memory cover the information to be transmitted. This results in the transmitted signal being orthogonal to other users and also orthogonal within the transmitting user's own signal bursts.

摘要： The present invention assigns a pair of user ID's to each user. The user ID's are used as addresses to access two orthogonal Walsh codes in a memory. Each Walsh code is 2n-bits in length and the memory size is 2n×2n. The orthogonal codes are then used to cover the information symbols for transmission. This results in the transmitted signal being orthogonal to other users and also orthogonal within the transmitting user's own signal bursts.

摘要： A satellite communication system provides multicast messaging services to subscriber units. Upon receipt of a multicast communication page from a satellite communication system network, a subscriber unit waits for a random delay period and then responds with an acknowledge signal. Based upon the time of receipt of the acknowledge signal, e.g., within one of a plurality of time periods, the satellite communication system network assigns the subscriber unit to one of a plurality of traffic channels. The satellite communication system infrastructure then sends a multicast communication message to the subscriber unit on the assigned traffic channel. The subscriber unit then waits for a random delay period and then responds with an acknowledge signal. The satellite communication system network then receives the acknowledge signal. Each of a plurality of subscriber units introduces a random delay before transmitting an acknowledge signal so that the satellite communication system network may determine which of the subscriber units received the multicast communication system message.
