초록 ▼

Implementing a method for a handover between mobile switching centers (MSC-A, MSC-B) of a cellular mobile network in high-speed data transmission wherein several channels are allocated to a mobile station (MS). In the method, the first mobile switching center (MSC-A) indicates to the second mobile switching center (MSC-B) at least the minimum number of channels required over the connection. The second mobile switching center (MSC-B) attempts to allocate at least the indicated minimum number of channels. The second mobile switching enter (MSC-B) transmits to the first mobile switching center (MSC-A) data about the channels it has allocated and at least one handover number (HON). The first mobile switching (MSC-A) may use the same handover number (HON) to perform a handover to each subchannel. According to a preferred embodiment of the invention, as many handover numbers (HON) are allocated directly as there are channels allocated to the connection.

대표청구항 ▼

[ What is claimed is:] [1.]1. A method for performing a handover between a first mobile switching center and a second mobile switching center of a mobile network in a high-speed data transmission wherein a mobile station has been allocated several channels, the method comprising:indicating from the first mobile switching center to the second mobile switching center at least a minimum number of channels required for a connection between the first and the second mobile switching centers;attempting to allocate at least the indicated minimum number of channels required for the connection by the second mobile switching center;transmitting from the second mobile switching center to the first mobile switching center data about channels the second mobile switching center has allocated including a number of channels and a handover number;using the handover number by the first mobile switching center to perform the handover; andusing the same handover number by the first mobile switching center a number of times as indicated by the number of the channels,wherein the second mobile switching center transmits to the first mobile switching center the number of the channels the second mobile switching center has allocated.
