1. A system, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor of the system, facilitate performance of operations, the operations comprising:
retrieving a first system information block (SIB) data structure, the SIB data structure including information about a group of neighbor cells in a communication network;
determining whether a neighbor cell of the group of neighbor cells is a bandwidth reduced mode cell capable of supporting a bandwidth reduced mode, the bandwidth reduced mode including selectively, temporarily reducing bandwidth usage by the neighbor cell of the group of cells;
in response to determining that the neighbor cell of the group is capable of supporting the bandwidth reduced mode, filtering information of the first SIB data structure by mapping the first SIB data structure to a bandwidth reduced mode neighbor cell data structure, wherein the mapping comprises copying neighbor cell information of the neighbor cell to the bandwidth reduced mode neighbor cell data structure, the bandwidth reduced mode neighbor cell data structure including a subset of cells of the group of neighbor cells and wherein the mapping further comprises excluding, from the bandwidth reduced mode neighbor cell data structure, information about neighbor cells of the group of neighbor cells that do not support the bandwidth reduced mode; and
communicating the bandwidth reduced mode neighbor cell data structure to a bandwidth reduced mobile device for use by the bandwidth reduced mobile device when connecting to a neighbor cell of the subset of the group of neighbor cells to thereby reduce use of network bandwidth by the bandwidth reduced mobile device.
