However, even if the number of communication channels can be increased in this way, since the number of control channels cannot be increased, the traffic of each control channel increases, and the control channel is often in a bottleneck state.
[0007] In addition, the above-mentioned wireless packet link channel establishment request is one of the causes of the bottleneck of the control channel because the communication channel to be added is not connected and can only be sent through the control channel when the link is added.
[0008] In addition, the control channel is shared by a plurality of original communication channels. In the case of the TDMA method, one of the time slots for time-division transmission and reception is used as the control channel. Therefore, there is a time lag in the transmission and reception of the control channel.
Therefore, it takes time to send a link establishment request and a link allocation at the time of link addition and inactive restoration, and as a result, it takes time to link addition and inactive restoration.
Therefore, as described above, since the traffic of the control channel increases, it takes a considerable time

The invention relates to a mobile communication system for relaxing bottleneck of control channel. In the mobile communication system, a base station device (2) and a mobile station device (3) which are communicated with each other by using at least one control channel and a plurality of communication channels; the mobile communication system is provided with an extended assignment instructing part (76) for instructing the transmission of the link channel assignment of other communicable communication channels from the base station device (2) to the mobile station device (3) by using the channel during communication; corresponding to the link channel assignment, the communication is conducted by using the communication channel shown by the link channel assignment between the mobile station device (3) and the base station device (2).
Description
technical field [0001] The invention relates to a mobile communication system and a connection control method, especially a link control method in a multi-link connection. Background technique [0002] In the mobile communication system represented by PHS (Personal Handyphone System) in the past, communication is performed by using multiple links in one call, compared with the case of using only one link. The connection method for communication is called a multi-link connection. In the case of performing this multi-link connection, usually, first, one link is used for connection, and then other links are connected (increased). By doing so, it is possible to increase the number of links to be used in accordance with the status of empty links. Specifically, for example, there is a method of adding links using the technology described in Patent Document 1. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2000-102055. [0004] Here, in the above-mention...
