Configuring signaling radio bearer information in a user equipment protocol stack
View Patent ↗In accordance with the teachings described herein, systems and methods are provided for configuring signaling radio bearer information in a user equipment protocol stack. A wireless network may be used that includes a radio access network for transmitting information between a user equipment device and a core network. An instruction may be received to generate a signaling radio bearer configuration information element (IE) that includes configuration information for a pre-selected number of signaling radio bearers. The signaling radio bearer configuration IE may then be generated, while ensuring that the signaling radio bearer configuration IE includes configuration information for a required minimum number of signaling radio bearers. The signaling radio bearer configuration information element may be transmitted from the radio access network to the user equipment device for use in configuring the signaling radio bearers in the user equipment device.
1. A network component comprising:
a processor configured to receive an instruction to generate a signaling radio bearer configuration information element (IE) that includes configuration information for a pre-selected number of signaling radio bearers, generate the signaling radio bearer configuration IE, determine whether duplicate configuration information is included in the signaling radio bearer configuration IE, determine which signaling radio bearers have been previously configured on a user equipment (UE), and ensuring the signaling radio bearer configuration IE includes configuration information for all remaining necessary signaling radio bearers for the UE, but not the radio bearers that have been previously configured on the UE.
2. The network component of claim 1 , wherein the processor is further configured to, when the signaling radio bearer configuration IE includes configuration information for all necessary signaling radio bearers, configure all the signaling radio bearers.
3. The network component of claim 1 , wherein the processor is further configured to, when the signaling radio bearer configuration IE does not include configuration information for all necessary signaling radio bearers, select default configuration values for one or more signaling radio bearers, and configure the one or more signaling radio bearers.
4. A method performed by a network component, the method comprising:
receiving an instruction to generate a signaling radio bearer configuration information element (IE) that includes configuration information for a pre-selected number of signaling radio bearers;
generating the signaling radio bearer configuration IE;
determining whether duplicate configuration information is included in the signaling radio bearer configuration IE;
determining which signaling radio bearers have been previously configured on a user equipment (UE); and
ensuring the signaling radio bearer configuration IE includes configuration information for all remaining necessary signaling radio bearers for the UE, but not the radio bearers that have been previously configured on the UE.
5. The method of claim 4 , further comprising:
when the signaling radio bearer configuration IE includes configuration information for all necessary signaling radio bearers, configuring all the signaling radio bearers.
6. The method of claim 4 , further comprising:
when the signaling radio bearer configuration IE does not include configuration information for all necessary signaling radio bearers, selecting default configuration values for one or more signaling radio bearers; and
configuring the one or more signaling radio bearers.
