Appl. No.:

09/892222

Assignee:

MOTOROLA, INC

International Classification:

H04Q007/20

US Classification:

455/450000, 455/452000

Abstract:

A method for Radio Network Controller (RNC) initiated Radio Access Bearer (RAB) negotiation or renegotiation/reconfiguration in a communication system that includes a core network and user equipment coupled to an RNC in a Universal Terrestrial Radio Access Network. When the core network establishes a service (e.g. voice call, web surfing session) with the user equipment, a RAB is set up for that service. The RAB includes certain parameters that effect the quality of the service. As the RNC monitors radio conditions, it may determine that one or more of the RAB parameters need to be modified. The RNC will initiate a RAB renegotiation/reconfiguration procedure by sending a RAB Modification Request Message to the CN specifying that a modification to the RAB is needed and the manner is which the modification should be affected. The CN may send a RAB Assignment Request Message informing the RNC whether the modification is acceptable.

International Classification:

H04Q 7/20

US Classification:

4554351

Abstract:

A method for managing allocation of connection identifiers (CIDs) to a wireless device in a network is provided. The method comprises allocating a CID to at least first wireless device based on a predefined criteria. The CID is allocated for at least one service accessed by the wireless device. The CID includes predetermined bit locations. The predetermined bit locations includes first predetermined bit locations and second predetermined bit locations. Further, the method comprises instructing the at least first wireless device to be responsive to messages that contain predetermined bit locations from the CID.

International Classification:

H04Q 7/20

US Classification:

455458

Abstract:

A method and corresponding entity for optimizing paging process in a communication network. The method comprises of sending () the paging signal to the at least one access point in a group associated with the current priority level and determining () whether a page response is received from the at least one access point in the group associated with the current priority level. The method includes updating the () the group associated with the current priority level based on the mobility observed at each access point in the group. The method further comprises assigning () a next priority level in the list of priority levels as the current priority level and repeating the above steps until the page response is received.

Assignee:

Nokia Siemens Networks Oy - Espoo

International Classification:

H04W 24/02

US Classification:

370252

Abstract:

Monitoring within a network a history of bits throughput to a base station over each of a plurality of time intervals, monitoring within the network a physical resource block utilization level over each of the plurality of time intervals, determining a ratio of the history of bits to the utilization level for each of the plurality of time intervals, determining an updated history of bits for each of a plurality of upcoming time intervals, estimating an updated utilization level in response to the updated history of bits and the ratio, generating messaging to at least one additional network element conveying the estimated updated physical resource block utilization level, and adjusting at least one of a prefilling process or a prefetching process in response to the updated utilization level.
