Abstract
A mobile station (MS), a base station subsystem (BSS), and various methods are described herein that enable the MS to receive acknowledgement of an access attempt for performing a multilateration timing advance (MTA) procedure using an Access Burst method without also being assigned resources.
Claims18
A mobile station configured to interact with a base station subsystem (BSS), the mobile station enabled for power efficient operation (PEO) and capable of performing a multilateration timing advance (MTA) procedure, the mobile station comprising:
- a processor;
- and,
- a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the mobile station is operable to:
- receive an MTA request message for the mobile station to perform a radio access part of the MTA procedure;
- transmit, to the BSS, a multilateration request message that indicates an Access Burst method for performing the MTA procedure;
- receive, from the BSS, an assignment message acknowledging that the BSS received the multilateration request message without assigning radio resources for the mobile station;
- determine from an indication included in the assignment message that no Temporary Block Flow (TBF) resources are assigned to the mobile station;
- and
- in response to determining from the indication that no TBF resources are assigned to the mobile station, determine if the assignment message matches the multilateration request message transmitted to the BSS.
A method in a mobile station configured to interact with a base station subsystem (BSS), the mobile station enabled for power efficient operation (PEO) and capable of performing a multilateration timing advance (MTA) procedure, the method comprising:
- receiving an MTA request message for the mobile station to perform a radio access part of the MTA procedure;
- transmitting, to the BSS, a multilateration request message that indicates an Access Burst method for performing the MTA procedure;
- receiving, from the BSS, an assignment message acknowledging that the BSS received the multilateration request message without assigning radio resources for the mobile station;
- determining from an indication included in the assignment message that no Temporary Block Flow (TBF) resources are assigned to the mobile station;
- and
- in response to determining from the indication that no TBF resources are assigned to the mobile station, determining if the assignment message matches the multilateration request message transmitted to the BSS.
A Base Station Subsystem (BSS) configured to interact with a mobile station, the mobile station enabled for power efficient operation (PEO) and capable of performing a multilateration timing advance (MTA) procedure, the BSS comprising:
- a processor;
- and,
- a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the BSS is operable to:
- receive, from the mobile station, a multilateration request message that indicates an Access Burst method for performing the MTA procedure;
- set a value of a first information element (IE) of an assignment message to indicate that no Temporary Block Flow (TBF) resources are assigned to the mobile station;
- set a Short ID field value included in a second IE of the assignment message to a Short ID field value included in the multilateration request message;
- and
- transmit, to the mobile station, the assignment message acknowledging that the BSS received the multilateration request message without assigning radio resources for the mobile station.
