If the content from the packet data network is cached at the edge server, the mapping service redirects the user equipment to request the content from the edge server across a second PDN connection. By using a mapping service located after the packet data network gateway, the content requests may have already passed restrictions such as parental controls. ## Claims ### Claim 1 A method performed by a user equipment in communication with first packet data network using a first packet data network connection, the method comprising: receiving, from a mobile core network, a message comprising an indication for the user equipment to access data from a second packet data network using a second packet data network connection, wherein the mobile core network generates the message based on a data request from the user equipment after the data request has reached an anchor of the first packet data network connection; connecting, using the second packet data network connection, to the second packet data network; and accessing, using the second packet data network connection, data from the second packet data network. ### Claim 2 (depends on 1) The method of claim 1, wherein the message is a packet data network service advertisement request message. ### Claim 3 (depends on 2) The method of claim 2, wherein the packet data network service advertisement request message comprises an indication of one or more of: a security header type, a services advertisement type, an access point name, and a packet data network type. ### Claim 4 (depends on 1) The method of claim 1, further comprising: sending, to the mobile core network, a response comprising an indication that the message has been received by the user equipment. ### Claim 5 (depends on 1) The method of claim 1, wherein the anchor of the first packet data network connection comprises a packet data network gateway. ### Claim 6 (depends on 1) The method of claim 1, wherein receiving a message from the mobile core network comprises receiving the message from a mobility management entity of the mobile core network. ### Claim 7 (depends on 1) The method of claim 1, wherein the mobile core network determines, based at least on a location of the user equipment and a deep packet inspection of a data request from the user equipment, that the user equipment should connect to the second packet data network using the second packet data network connection in order to access the data. ### Claim 8 A user equipment in communication with first packet data network using a first packet data network connection, the user equipment comprising a processor and a memory, the memory storing computer-executable instructions which, when executed by the processor, cause the user equipment to perform operations comprising: receiving, from a mobile core network, a message comprising an indication for the user equipment to access data from a second packet data network using a second packet data network connection, wherein the mobile core network generates the message based on a data request from the user equipment after the data request has reached an anchor of the first packet data network connection; connecting, using the second packet data network connection, to the second packet data network; and accessing, using the second packet data network connection, data from the second packet data network. ### Claim 9 (depends on 8) The user equipment of claim 8, wherein the message is a packet data network service advertisement request message. ### Claim 10 (depends on 9) The user equipment of claim 9, wherein the packet data network service advertisement request message comprises an indication of one or more of: a security header type, a services advertisement type, an access point name, and a packet data network type. ### Claim 11 (depends on 8) The user equipment of claim 8, wherein the instructions, when executed, further cause the user equipment to perform operations comprising: sending, to the mobile core network, a response comprising an indication that the message has been received by the user equipment. ### Claim 12 (depends on 8) The user equipment of claim 8, wherein the anchor of the first packet data network connection comprises a packet data network gateway. ### Claim 13 (depends on 8) The user equipment of claim 8, wherein receiving a message from the mobile core network comprises receiving the message from a mobility management entity of the mobile core network. ### Claim 14 (depends on 8) The user equipment of claim 8, wherein the mobile core network determines, based at least on a location of the user equipment and a deep packet inspection of a data request from the user equipment, that the user equipment should connect to the second packet data network using the second packet data network connection in order to access the data. ### Claim 15 A computer-readable storage medium storing computer-executable instructions which, when executed by a processor of a user equipment in communication with first packet data network using a first packet data network connection, cause the user equipment to perform operations comprising: receiving, from a mobile core network, a message comprising an indication for the user equipment to access data from a second packet data network using a second packet data network connection, wherein the mobile core network generates the message based on a data request from the user equipment after the data request has reached an anchor of the first packet data network connection; connecting, using the second packet data network connection, to the second packet data network; and accessing, using the second packet data network connection, data from the second packet data network. ### Claim 16 (depends on 15) The computer-readable storage medium of claim 15, wherein the message is a packet data network service advertisement request message. ### Claim 17 (depends on 16) The computer-readable storage medium of claim 16, wherein the packet data network service advertisement request message comprises an indication of one or more of: a security header type, a services advertisement type, an access point name, and a packet data network type. ### Claim 18 (depends on 15) The computer-readable storage medium of claim 15, wherein the instructions, when executed, further cause the user equipment to perform operations comprising: sending, to the mobile core network, a response comprising an indication that the message has been received by the user equipment. ### Claim 19 (depends on 15) The computer-readable storage medium of claim 15, wherein receiving a message from the mobile core network comprises receiving the message from a mobility management entity of the mobile core network. ### Claim 20 (depends on 15) The computer-readable storage medium of claim 15, wherein the mobile core network determines, based at least on a location of the user equipment and a deep packet inspection of a data request from the user equipment, that the user equipment should connect to the second packet data network using the second packet data network connection in order to access the data.
