Abstract
Apparatuses, methods, and systems are disclosed for accessing a local data network via a mobile data connection. One apparatus (500) includes a processor (505) and a transceiver (525) that communicates with a mobile communication network. The processor (505) receives (605) a downlink data packet from a first data connection (303) over the mobile communication network, the first data connection (303) providing the apparatus (500) with access to a remote data network (125). The processor (505) determines (610), from the downlink data packet, whether the first data connection (303) provides access to a local data network (135) in addition to the remote data network (125). In response to the first data connection (303) providing access to the local data network (135), the processor (505) accesses (615) one or more services via the local data network (135).

Claim
1. An apparatus comprising:
a transceiver that communicates with a mobile communication network; a processor that: receives a downlink data packet from a first data connection over the mobile communication network, the first data connection providing the apparatus access to a remote data network; determines from the downlink data packet whether the first data connection provides access to a local data network in addition to the remote data network; and accesses one or more services in the local data network in response to determining that the first data connection provides access to the local data network.
2. The apparatus of claim 1, wherein determining from the downlink data packet whether the first data connection provides access to the local data network in addition to the remote data network comprises the processor examining a local access availability flag in a header of the downlink data packet, the local access availability flag indicating whether the first data connection provides access to the local data network.
3. The apparatus of claim 2, wherein the header further includes a charging rate parameter, the charging rate parameter indicating a charging rate applied to data traffic sent by the apparatus to the local data network via the first data connection.
4. The apparatus of claim 3, further comprising the processor informing an application installed at the apparatus of the charging rate applied to data traffic sent by the apparatus to the local data network.
5. The apparatus of claim 1, wherein determining from the downlink data packet whether the first data connection provides access to the local data network in addition to the remote data network comprises the processor determining whether a charging rate parameter is present in a packet header of the downlink data packet, the presence of the charging rate parameter indicating that the first data connection provides access to the local data network.
6. The apparatus of claim 1, wherein accessing one or more services in the local data network comprises the processor requesting IP configuration data by using a dynamic host configuration protocol (�DHCP�) request and configuring a virtual network interface for accessing the local data network via the first data connection with received IP configuration data.
7. The apparatus of claim 6, wherein the processor marks an uplink packet sent to the virtual network interface with a local access request flag, wherein the local access request flag requests routing the uplink packet to the local data network.
8. The apparatus of claim 1, wherein accessing one or more services in the local data network comprises the processor sending a service discovery request to the local data network.
9. The apparatus of claim 8, wherein sending the service discovery request comprises the processor sending a domain name system (�DNS�) query packet or a Simple Service Discovery Protocol (�SSDP�) packet marked with a local access request flag, wherein the local access request flag requests routing the DNS query packet or the SSDP packet to the local data network.
10. The apparatus of claim 1, wherein accessing one or more services in the local data network comprises the processor:
discovering a hypertext transport protocol (�HTTP�) proxy in the local data network; and sending HTTP traffic to the discovered HTTP proxy in the local data network.
11. The apparatus of claim 1, further comprising the processor:
determining whether an uplink packet is to be transmitted to the local data network; marking the uplink packet with a local access request flag, in response to determining that the uplink packet is to be transmitted to the local data network; and transmitting the uplink packet via the first data connection, wherein the local access request flag requests routing the uplink packet to the local data network.
12. A method comprising:
receiving, at a remote unit, a downlink data packet from a first data connection over a mobile communication network, the first data connection providing access to a remote data network; determining from the downlink data packet whether the first data connection provides access to a local data network in addition to the remote data network; and accessing one or more services in the local data network in response to determining that the first data connection provides access to the local data network.
13. The method of claim 12, wherein determining from the downlink data packet whether the first data connection provides access to the local data network in addition to the remote data network comprises examining a local access availability flag in a header of the downlink data packet, the local access availability flag indicating whether the first data connection provides access to the local data network.
14. The method of claim 13, wherein the header further includes a charging rate parameter in the header, the charging rate parameter indicating a charging rate applied to data traffic sent by a remote unit to the local data network via the first data connection.
15. The method of claim 14, further comprising the remote unit informing an application installed thereon of the charging rate applied to data traffic sent by a remote unit to the local data network.
16. The method of claim 12, wherein determining from the downlink data packet whether the first data connection provides access to the local data network in addition to the remote data network comprises determining whether a charging rate parameter is present in a packet header of the downlink data packet, the presence of the charging rate parameter indicating that the first data connection provides access to the local data network.
17. The method of claim 12, wherein accessing one or more services in the local data network comprises requesting IP configuration data by using a dynamic host configuration protocol (�DHCP�) request and configuring a virtual network interface for accessing the local data network via the first data connection with received IP configuration data.
18. The method of claim 17, wherein an uplink packet sent to the virtual network interface is marked with a local access request flag, wherein the local access request flag requests routing the uplink packet to the local data network.
19. The method of claim 12, wherein accessing one or more services in the local data network comprises sending a service discovery request to the local data network.
20. The method of claim 19, wherein sending the service discovery request comprises sending a domain name system (�DNS�) query packet or a Simple Service Discovery Protocol (�SSDP�) packet marked with a local access request flag, wherein the local access request flag requests routing the DNS query packet or the SSDP packet to the local data network.
