1. A method of supporting an MS during re-entry into a network, the method comprising:
determining if the MS is a member of a closed subscriber group associated with a first base station from a plurality of base stations; and
instructing, by the first base station, the MS to attempt re-entry into the network at another base station from the plurality of base stations in response to determining that the MS is not a member of the closed subscriber group associated with the first base station.
2. The method of claim 1, further comprising:
initiating, by the network, idle mode entry after re-authentication with the network if re-entry into the network was not caused by a power down request.
3. The method of claim 1, further comprising:
sending, by the network, a command to complete a power down process after re-authentication with the network if re-entry into the network was caused by a power down request.
4. A method of supporting an MS during re-entry into a network, the method comprising:
selecting a first base station from a plurality of base stations for re-entry into the network, wherein the first base station determines if the MS is a member of a closed subscriber group associated with the first base station; and
receiving instructions from the first base station to attempt re-entry into the network at another base station from the plurality of base stations if the MS is not a member of the closed subscriber group associated with the first base station.
5. The method of claim 4, further comprising:
initiating, by the MS, idle mode entry after re-authentication with the network if re-entry of the network was not caused by a power down request.
6. The method of claim 4, further comprising:
sending, by the MS, a command to complete a power down process after re-authentication with the network if re-entry of the network was caused by a power down request.
7. A system for supporting an MS during re-entry into a network, the method comprising:
means for determining if the MS is a member of a closed subscriber group associated with a first base station from a plurality of base stations; and
means for instructing the MS to attempt re-entry into the network at another base station from the plurality of base stations in response to determining that the MS is not a member of the closed subscriber group associated with the first base station.
8. The system of claim 7, further comprising:
means for initiating idle mode entry after re-authentication with the network if re-entry into the network was not caused by a power down request.
9. The system of claim 7, further comprising:
means for sending a command to complete a power down process after re-authentication with the network if re-entry into the network was caused by a power down request.
10. A system for supporting an MS during re-entry into a network, the method comprising:
means for selecting a first base station from a plurality of base stations for re-entry into the network, wherein the first base station determines if the MS is a member of a closed subscriber group associated with the first base station; and
means for receiving instructions from the first base station to attempt re-entry into the network at another base station from the plurality of base stations if the MS is not a member of the closed subscriber group associated with the first base station.
11. The system of claim 10, further comprising:
means for initiating idle mode entry after re-authentication with the network if re-entry of the network was not caused by a power down request.
12. The system of claim 10, further comprising:
means for sending a command to complete a power down process after re-authentication with the network if re-entry of the network was caused by a power down request.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A pressure vessel, comprising:
a vessel main body having a tank head section and a shell plate section; and
a protective member including a non -foamed thermally foamable material, which forms a heat insulating layer when being foamed, and placed to be brought into contact with and fixed to part of an outer surface of the tank head section.
2. The pressure vessel according to claim 1,
wherein the protective member includes a layer containing the thermally foamable material and a layer containing a buffer material.
3. The pressure vessel according to claim 2,
wherein the layer containing the buffer material is placed on inner side of the layer containing the thermally foamable material.
4. The pressure vessel according to claim 1,
wherein the the tank head section includes a first tank head section and a second tank head section, wherein
a safety valve operative to work at high temperature is provided on the first tank head section, and
the protective member is fixed to the second tank head section.
5. The pressure vessel according to claim 1,
wherein the protective member has an outer diameter that is equal to or smaller than outer diameter of the vessel main body.
6. The pressure vessel according to claim 1,
wherein the part of the tank head section brought into contact with and fixed by the protective member includes a region having a smallest wall thickness.
7. A production method of a pressure vessel, comprising:
producing a vessel main body including a tank head section and a shell plate section; and
bringing a protective member including a non-foamed thermally foamable material, which forms a heat insulating layer when being foamed, into contact with at least part of an outer surface of the tank head section to be fixed to the at least part of the outer surface of the tank head section.
