Abstract: The invention is directed to a method for cell selection in a cellular telecommunication system. According to the invention, cell identification information is attached as a parameter to an RRC message initiating the state change of the mobile station to the cell-connected state. Advantageously, the network selects a cell to be suggested as the cell for use by the mobile station in the cell-connected state, and the network indicates said cell by attaching cell identification as a parameter to said RRC message. Consequently, the mobile station may make the final selection of the cell, and indicate the selected cell to the network by attaching cell identification information as a parameter to a second RRC message, such as the response message to the RRC message initiating the state change.

Abstract: 264,529. Keberlein & Co., Akt.-Ges. Jan. 15, 1926, [Convention date]. Yams &c., treating with liquids.-The appearance, strength and other properties of artificial silks made of regenerated cellulose, are modified by treatment throughout with the following swelling-agents :-alkadi hydroxide solutions of 10-25 Be; sulphuric acid of above 43 BÚ strength; phosphoric acid of specific gravity above 50 Be; hydrochloric acid of above 20 BÚ; nitric acid of above 35 BÚ strength; or mixtures of such acids including mixtures of nitric and sulphuric acids; concentrated salt solutions, in particular zinc chloride solution of above 50 BÚ and calcium sulphocyanide solution above 25 BÚ; and copper oxide ammonia solution containing more than 0.3 per cent copper. To the swelling-agent may be added substances that moderate its action, such as mono- and poly-hydric alcohols, heterocyclic bases, formaldehyde or ammonium salts. The treatment is preferably carried out at normal temperature; but temperatures below 0 C. may be employed, while if a salt solution is employed the temperature may be raised up to 100 C. The process is applicable to the treatment of loose, spun, woven or made-up material, and the artificial silk may be alone or mixed with other fibres; it may also be applied to staple fibre. The material may be in the loose condition or under tension. The effect produced depends on the conditions; generally it comprises more or less loss of lustre, a gain in translucency and transparency, a reduction in the stiffness of the material, and an increase in the strength; with a mixture of nitric and sulphuric acids, the product may be non-translucent and lustreless or it may show a soft broken-up lustrous effect resembling crepe-and materials treated in this way are advantageously denitrated. In examples, the silk is treated with soda lye of 20 BÚ strength at normal temperature, or with sulphuric acid of 49 BÚ at - 10 C, or with nitric acid of 40 BÚ at normal temperature, or with a nitrating mixture of 4 parts of sulphuric acid and one part nitric acid, or with zinc chloride of 67 BÚ at 40 C.
