Apparatus, method and computer program product providing simultaneous radio resource and service requests
A method includes, at a user equipment, combining a message requesting the radio resource connection and a message requesting at least one service into a single message. The single message is transmitted from the user equipment to a network element in a wireless network. Another method includes receiving, from a user equipment, a single message including both a message requesting a radio resource connection and a message requesting at least one service. In response to the message requesting radio resource connection, performing radio resource control connection establishment for the user equipment in order to establish the radio resource control connection between the user equipment and at least one of a plurality of network elements of a wireless network. In response to the message requesting at least one service, performing service request procedures for the user equipment, wherein at least part of the radio resource control connection establishment and at least part of the service request procedures are performed in parallel.
1. A method comprising:
forming, at a user equipment, a message comprising a radio resource connection request and a service-initiation request to enable a wireless network supporting parallel execution of a radio resource establishment and a service request procedure, the service-initiation request specifies a particular service requested by the user equipment and initiates a signaling connection for the particular requested service, the signaling connection being between the user equipment and the wireless network;
transmitting, from the user equipment, the message from the user equipment to a network element in the wireless network, the message for establishing the radio resource connection and initiating the signaling connection;
receiving, at the user equipment, a RRC (radio resource control) connection setup message from the network element, the RRC connection setup message confirming that the radio resource connection is established; and
in response to receiving the RRC connection setup message from the network element, initiating a synchronization procedure in a lower layer when a dedicated channel state is required, and indicating to an upper layer within the user equipment that the service-initiation request has been successfully transferred to the network.
2. The method of claim 1 , wherein the message comprises a first portion for the radio resource connection request and a second portion for the service-initiation request.
3. The method of claim 2 , wherein the service-initiation request is encoded as a bit string.
4. The method of claim 3 , wherein the first portion is encoded in accordance with a first protocol and the second portion is encoded in accordance with a second protocol.
5. The method of claim 4 , wherein the first protocol comprises an Abstract Syntax Notation One (ASN.1) protocol and the second protocol comprises a non-access stratum protocol.
6. The method of claim 2 , wherein the service-initiation request is an initial direct transfer request.
7. The method of claim 2 , wherein the first portion and the second portion are each encoded using a single protocol.
8. An apparatus comprising:
at least one processor; and
at least one non-volatile memory including computer program code, the computer program code, when executed by the processor, configured to cause the apparatus to perform at least the following:
form a message comprising a radio resource connection request and a service-initiation request to enable a wireless network supporting parallel execution of a radio resource establishment and a service request procedure, the service-initiation request specifies a particular service requested by the apparatus and initiates a signaling connection for the particular requested service, the signaling connection being between the apparatus and the wireless network;
transmit the message to a network element in the wireless network, the message for establishing the radio resource connection and initiating the signaling connection;
receive a RRC (radio resource control) connection setup message from the network element, the RRC connection setup message confirming that the radio resource connection is established; and
in response to receiving the RRC connection setup message from the network element, initiate a synchronization procedure in a lower layer when a dedicated channel state is required, and indicate to an upper layer within the apparatus that the service-initiation request has been successfully transferred to the network.
9. The apparatus of claim 8 , wherein the message comprises a first portion for the radio resource connection request and a second portion for the service-initiation request.
10. The apparatus of claim 9 , wherein the service-initiation request is encoded as a bit string.
11. The apparatus of claim 10 , wherein the first portion is encoded in accordance with a first protocol and the second portion is encoded in accordance with a second protocol.
12. The apparatus of claim 11 , wherein the first protocol comprises an Abstract Syntax Notation One (ASN.1) protocol and the second protocol comprises a non-access stratum protocol.
13. The apparatus of claim 9 , wherein the service-initiation request is an initial direct transfer request.
14. The apparatus of claim 9 , wherein the first portion and the second portion are each encoded using a single protocol.
15. An non-transitory computer readable memory tangibly embodying a program of machine-readable instructions executable by one or more processors to perform operations comprising:
forming, at a user equipment, a message comprising a radio resource connection request and a service-initiation request to enable a wireless network supporting parallel execution of a radio resource establishment and a service request procedure, the service-initiation request specifies a particular service requested by the user equipment and initiates a signaling connection for the particular requested service, the signaling connection being between the user equipment and the wireless network;
transmitting, from the user equipment, the message from the user equipment to a network element in the wireless network, the message for establishing the radio resource connection and initiating the signaling connection;
receiving, at the user equipment, a RRC (radio resource control) connection setup message from the network element, the RRC connection setup message confirming that the radio resource connection is established; and
in response to receiving the RRC connection setup message from the network element, initiating a synchronization procedure in a lower layer when a dedicated channel state is required, and indicating to an upper layer within the user equipment that the service-initiation request has been successfully transferred to the network.
16. The non-transitory computer readable memory of claim 15 , wherein the message comprises a first portion for the radio resource connection request and a second portion for the service-initiation request.
17. The non-transitory computer readable memory of claim 16 , wherein the service-initiation request is encoded as a bit string.
18. The non-transitory computer readable memory of claim 17 , wherein the first portion is encoded in accordance with a first protocol and the second portion is encoded in accordance with a second protocol.
19. The non-transitory computer readable memory of claim 15 , wherein the first protocol comprises an Abstract Syntax Notation One (ASN.1) protocol and the second protocol comprises a non-access stratum protocol.
20. The non-transitory computer readable memory of claim 16 , wherein the service-initiation request is an initial direct transfer request, and the first portion and the second portion are each encoded using a single protocol.
