Abstract
in the context of “operator-controlled Wi-Fi” as in 3GPP TR 37,834 v12,0,0 “Study on Wireless Local Area Network (WLAN)”, both in solution2 and solution3, WLAN identifiers need to be communicated between the radio access network, RAN, and the UE. However, WLAN identifiers (e.g., SSIDs, BSSIDs, ESSIDs, HESSIDs, Realm identifiers, NAIs, PLMN identifiers, Domain Name lists, . . . ) are large (e.g., SSID may be up to 32 bytes) and cause a large overhead in the wireless interface. This problem is solved by providing an indexed listing of WLAN Identifiers and by only exchanging the indices across the wireless interface; Preferably, some WLANs may have several indices, and each index may also be used to convey the action to take by the UE.
Claims20
A method of operating a terminal device, the method comprising:
- maintaining one or more indices and a mapping between the one or more indices and respective network identifiers, each network identifier identifying a different network node;
- in communications between the terminal device and a first network, using the one or more indices to identify at least one network node;
- and
- for a first index being mapped to two or more network identifiers, signaling, in the communications, a number of network nodes that correspond to the first index.
A terminal device, comprising:
- a memory storing instructions;
- and
- a processor configured to execute the instructions to:
- maintain one or more indices and a mapping between the one or more indices and respective network identifiers, each network identifier identifying a different network node;
- in communications between the terminal device and a first network, use the one or more indices to identify at least one network node;
- and
- for a first index being mapped to two or more network identifiers, signal, in the communications, a number of network nodes that correspond to the first index.
A non-transitory computer-readable medium comprising a computer program code that, when executed by a processor coupled to a terminal device, causes the terminal device to perform operations comprising:
- maintaining one or more indices and a mapping between the one or more indices and respective network identifiers, each network identifier identifying a different network node;
- in communications between the terminal device and a first network, using the one or more indices to identify at least one network node;
- and
- for a first index being mapped to two or more network identifiers, signaling, in the communications, a number of network nodes that correspond to the first index.
