Problems solved by technology

[0005] In addition, even if the location information management server can install a configuration for managing the location information of a plurality of mobile stations in different waiting states on the same layer, the location information management server needs to dually manage the location registration corresponding to the multiple waiting states. area, resulting in an excessive burden on location information management

Embodiment approach 1

[0273] Next, a first embodiment of the second part will be described with reference to the drawings.

[0274] (Mobile communication system and configuration of each device)

[0275] figure 1 Demonstrate the composition of the mobile communication system. The mobile communication system is composed of a location information management server 5 , a communication network 4 , a plurality of mobile stations 1 , and a plurality of wireless base stations 2 . The location information management server 5 is connected to the communication network 4 and manages location information on the location of the mobile station 1 and reception group information on reception groups allocated to the mobile station 1 . In addition, the location information management server 5 assigns, to each mobile station 1 , a designated reception group at a time when it is to receive a paging signal, and notifies the mobile station 1 of designating a reception group, and the like. The location information ma...

Embodiment approach 2

[0328] Next, Embodiment 2 of the second part will be described with reference to the drawings.

[0329] (Mobile communication system and configuration of each device)

[0330] In the mobile communication system of this embodiment, the Figure 22A ~ Figure 22C The database 24 of the shown location information management server 5 is replaced by Figure 25A ~ Figure 25C The database 224 shown is accordingly the same as the actual mobile communication system shown in FIG. 21A except that part of the operations of the measurement unit 22 and the control unit 23 of the location information management server 5 are different. Therefore, overlapping explanations for substantially the same parts are omitted.

[0331] Database 224, by Figure 25A The shown position management table 224a, Figure 25B The shown real-time level reception group management table 224b, Figure 25C The shown non-real-time class reception group management table 224c is constituted.

Abstract

An object is to implement smooth execution of management of location information of a mobile station according to states of the mobile station varying with time. Based on a notification of transition into a sleep state from the mobile station, transmitted upon a timeout of a sleep state determination timer with neither packet transmission nor reception at the mobile station, it is determined that the mobile station has moved into the sleep state, and control processing in the link layer is executed (S12) (the control processing in the link layer carried out when the mobile station moves between cells). Thereafter, based on a notification of transition into an idle state from the mobile station, which is transmitted upon a timeout of an idle state determination timer with neither packet transmission nor reception at the mobile station, it is determined that the mobile station has moved into the idle state, and control processing in the network layer is executed (S14) (the control processing in the network layer carried out when the mobile station changes its location registration area). In this way, the control processings are executed based on the states of the mobile station according to durations in which neither packet transmission nor reception is conducted at the mobile station.

Description

technical field [0001] The present invention relates to a server, a mobile communication system, a position information management method, a wireless base station, a mobile station, a calling method of the mobile communication system, and a mobile communication method. Background technique [0002] Assuming a packet communication model such as Web browsing, in this packet communication mode, there are two periods: a period in which the mobile station continuously downloads packets, and a period in which the mobile station browses pages after downloading (web browsing period). Focusing on this feature, the technology of saving battery power by intermittently accepting the control signal sent from the wireless base station during web page browsing by the mobile station is described in "Adaptive Battery Power Saving Control Method in IN2001-198 Multimedia Wireless Packet Communication (Electronic Information and Communication Society and Information Network Research Society, Ma...
