    • A network controller (NC) (105) that reduces the overhead exchanges for mobility events in a communications network is disclosed. Such a communications network is constituted by a wireless multihop communications network comprising a multihop chain (MH) (130) that wirelessly connects in series wireless communications entities (WCE) (110, 115) for relaying and the network controller as a first entity. Within the wireless multihop communications network a mobile node (MN) (125) wirelessly communicates with the wireless communications entity (115) located at the end of the multihop chain (130). In a communications network, the network controller (105) manages the multihop chain (130), and upon determining that the communications path has to be changed by a mobility event (ME) (141), it establishes a wireless communication between the mobile node (125) and a wireless communications entity (120) by expanding (132) the multihop chain (130).

    • A two-dimensional encoder stores data on a holographic memory. The encoder encodes data of k bits (where k is an integer and k ≥ 3) into n pixels arranged two-dimensionally (where n is an integer and n ≥ 6). The encoder includes a first processing section 31 for classifying the n pixels into first and second groups of subblocks 11 and 12 using k1 bits out of the data of k bits (where k1 is an integer and k1 ≥ 1). Each of the subblocks 11 in the first group consists of m pixels (where m is an integer and m ≥ 2), and the number of the subblocks 11 forming the first group is s1 (where s1 is an integer and s1 ≥ 2). Each of the subblocks 12 in the second group also consists of m pixels, and the number of the subblocks 12 forming the second group is s2 (where s2 is an integer and s2 ≥ 1). The encoder further includes a second processing section 32 for turning ON p pixels (where p is an integer and 1 ≤ p ≤ m/2) out of the m pixels forming each subblock 11 in the first group and turning OFF all of the m pixels forming each subblock 12 in the second group using the other k2 bits of the data of k bits (where k2=k-k1).

    • Method for informing a mobile terminal (MN), which is located in a first cell, on system information of a second cell. In particular, pointers to the system information are transmitted from the base station of the first cell to the mobile node, while the mobile node is located in the first cell. The MN processes said pointer, comprising e.g. information on the transmission format and timing of system information in the second cell. Using an acquisition gap assigned by the network, the MN changes the frequency to the second frequency so as to acquire the system information based on the previously received scheduling information. Thus, the acquisition time for important system information may be reduced, as no Master Information Block on the second frequency has to be processed first, in order to acquire the system information.
