摘要:
A communication system comprises a wireless access node having a plurality of ports and a control system. The wireless access node is configured to exchange wireless communications over the ports with wireless communication devices that are individually identified by device identifiers. The control system is configured to individually allocate the wireless communication devices into categories based on the device identifiers and determine one of the categories having a majority of the wireless communication devices. The control system is configured to configure the ports of the wireless access node to utilize a MIMO 2T2R mode for exchanging the wireless communications if the one category having the majority of the wireless communication devices comprises a first data rate capability, and to configure the ports of the wireless access node to utilize a MIMO 4T4R mode for exchanging the wireless communications if the one category having the majority of the wireless communication devices comprises a second data rate capability.

Disclosed is a method and system to help reduce the extent of roaming or use of lower priority coverage areas in a wireless communication system, by selectively managing the level of noise in a preferred coverage area. A network entity will detect that a particular coverage area has a high rate or roaming or that another coverage area (e.g., a collocated or adjacent coverage area) has a high rate of use, and the network entity will responsively reduce a noise threshold in the particular coverage area so as to then tolerate less noise in the coverage area before taking affirmative action to reduce the level of noise, and thus optimally to reduce the extent of roaming or use of less preferred coverage.

During connection establishment, an access network and/or an access terminal may decide whether to transmit bearer-traffic data rather than null-traffic data based on a channel quality of a wireless link. For example, if the access network has forward bearer-traffic data ready for transmission to the access terminal during connection establishment, the access network may decide to transmit that forward bearer-traffic data rather than forward null-traffic data in response to determining that a forward-channel quality of the wireless link is sufficient to carry such data. As another example, if the access terminal has reverse bearer-traffic data ready for transmission to the access network during connection establishment, the access terminal may decide to transmit that reverse bearer-traffic data rather than reverse null-traffic data in response to determining that a reverse-channel quality of the wireless link is sufficient to carry such data.

Embodiments disclosed herein provide systems and methods for dynamically transferring between multiple-input and multiple-output (MIMO) transmit modes based on a usage level of a wireless access node. In a particular embodiment, a method provides transferring wireless communications to a wireless communication device via a plurality of ports in a wireless access node on a wireless communication network. The method further provides determining an access node usage level for the wireless access node. If the access node usage level satisfies a condition for access node usage, the method provides configuring the plurality of ports to use a MIMO 2 transmit-2 carrier mode for transmitting the wireless communications. If the access node usage level does not satisfy the condition for access node usage, the method provides configuring the plurality of ports to use a MIMO 4 transmit-1 carrier mode for transmitting the wireless communications.

An access network may be maintaining data indicating which of its coverage areas have a short occupancy time. The access network may then conduct a first paging of an access terminal in each coverage area in a first set of coverage areas, the first set including a subset of coverage areas having a short occupancy time. Thereafter, the access network may determine that it has not received a response to the first paging from the access terminal during a first timeout period, which is preferably shorter than a predefined paging timeout period. In response, the access network may conduct a second paging of the access terminal in only each coverage area in the subset of coverage areas (i.e., the coverage area(s) in the first set of coverage areas that have the short occupancy time).
摘要:
A method and apparatus for improved idle handoff a mobile station in a wireless communication system. While idling in a particular sector of the system, the mobile station will select a target sector based on a determination that the target sector has the same number of channels as the current sector, such as the same number of paging channels and perhaps the same number of frequency channels as the current sector. The mobile station will then engage in an idle handoff from the current sector to the selected target sector. By striving to hand off to a sector that has the same number of channels, particularly the same number of paging channels, the mobile station may avoid having to hash onto a channel in the target sector and may thereby minimize the likelihood of missing a page message sent while the mobile station was busy hashing onto the channel.
摘要:
A first wireless network serves a wireless device and generates loading information. A second wireless network also serves the wireless device and also generates loading information. The first and second wireless networks share a plurality of wireless access points. A paging system receives a page request for the wireless device for delivery over the first network. The paging system processes the loading information to determine if paging assistance from the second network is applicable. If so, the paging system transfers a first page to the second network for delivery to the wireless device. The paging system receives a page response from the wireless device over the second network and processes the response to identify the shared wireless access point serving the wireless device. The paging system transfers a second page to the first wireless network for delivery to the wireless device through the identified shared wireless access point.
摘要:
A wireless communication device (WCD) may be able to acquire wireless service from preferred wireless coverage areas that are managed by the WCD's service provider. In some cases, the WCD may instead use wireless service from non-preferred wireless coverage areas of the service provider's roaming partners. In order to save roaming fees, the service provider's RAN may determine when the WCD is likely to roam to a non-preferred wireless coverage area. In response to this determination, the RAN may transmit a redirect message to the WCD, causing the WCD to switch from one preferred wireless coverage area to another preferred wireless coverage area. In some situations, the RAN may transmit such a redirect message because the WCD has reported that it has a low remaining battery life.

A method to manage a call in a communication system and an access node of the communication system are disclosed. The method includes receiving, by the communication system, a call request for a voice call from a first device to communicate with a second device, wherein the second device is a subscriber of the communication system, and transmitting, by the communication system to the first device, a first message comprising an indication that the second device is operating in a text message-only mode, when the second device is roaming and a roaming usage of the second device meets a roaming criteria. The access node may be configured to transmit to the first device the first message, when the first device requests to establish a call with the second device through the access node, the second device is roaming, and a roaming usage of the second device meets the roaming criteria.
