Policy control for restricted local operator services
A wireless device receives from a base station of a network, a system information block indicating that the network supports restricted local operator services (RLOS). The wireless device sends to the base station, a radio resource control connection (RRC) connection request message indicating a request for an RRC connection with the base station. The RRC connection request message comprises an establishment cause indicating that the RRC connection is for the RLOS. The wireless device receives an RRC connection setup message in response to the RRC connection request message. The RRC connection setup message indicates an acceptance of the request for the RRC connection for the RLOS. The wireless device sends a first RRC message in response to the RRC connection setup message.
1. A method comprising:
receiving, by a wireless device from a base station, a system information block (SIB) indicating that restricted local operator services (RLOS) are supported by a public land mobile network (PLMN);
transmitting, based on the SIB indicating the support for the RLOS, a preamble;
receiving, from the base station, a random access response to the preamble;
transmitting, based on the random access response, by the wireless device to the base station, at least one first radio resource control (RRC) message comprising:
a first information element indicating, to the base station, that an RRC connection of the wireless device is for the RLOS; and
a second information element comprising an attach request message indicating, to a mobility management entity (MME) configured with an RLOS access point name, that the attach request of the wireless device is for the RLOS; and
receiving, from the base station and via the RRC connection for the RLOS, a second RRC message comprising an attach accept message indicating acceptance of the RLOS by the MME.
2. The method of claim 1 , wherein the RLOS is provided by an operator of the PLMN.
3. The method of claim 1 , wherein the at least one first RRC message further comprises an identifier of the wireless device.
4. The method of claim 1 , wherein the at least one first RRC message further comprises an RRC connection setup complete message.
5. The method of claim 1 , wherein the at least one first RRC message comprises an RRC connection setup message.
6. The method of claim 1 , wherein the system information block further indicates a level of support for the RLOS.
7. The method of claim 1 , wherein the preamble is a random access preamble for initiation of a random access procedure for an RRC connection.
8. The method of claim 1 , wherein the attach accept message comprises RLOS information comprising at least one of:
a first information element indicating a service type of at least one RLOS allowed for the wireless device; or
a second information element indicating application information for the service type.
9. The method of claim 8 , wherein the application information comprises at least one of:
a service data flow filter;
an application identifier; or
a uniform resource locator (URL).
10. The method of claim 8 , further comprising sending, by the wireless device and based on the RLOS information, packets of the at least one RLOS.
11. The method of claim 1 , wherein the RLOS comprises an emergency service for the wireless device.
12. The method of claim 1 , wherein the RLOS comprises a voice over long term evolution (VOLTE) service for the wireless device.
13. The method of claim 1 , further comprising receiving an RRC connection setup message indicating an acceptance of an RRC connection.
14. The method of claim 1 , further comprising sending, by the MME to a serving gateway (SGW), a create session request message comprising a parameter indicating a session or a bearer is established for the RLOS.
15. The method of claim 14 , further comprising sending, by the SGW to a packet data network gateway (PGW), a create session request message comprising the parameter indicating the session or the bearer is established for the RLOS.
16. The method of claim 15 , further comprising sending, by the PGW to a policy and charging rules function (PCRF), an internet protocol connectivity access network (IP-CAN) session establishment request comprising a RLOS indication indicating a request for a policy for the RLOS.
17. The method of claim 16 , further comprising determining, by the PCRF and based on the RLOS indication, one or more policies of at least one RLOS, wherein the one or more policies comprise RLOS information.
18. The method of claim 16 , further comprising determining, by the PCRF and based on RLOS information received from a network function, one or more policies of at least one RLOS, wherein the one or more policies comprise the RLOS information.
19. The method of claim 18 , further comprising sending, by the PCRF to the PGW, an IP-CAN session establishment response message comprising the RLOS information.
