Abstract
A method and corresponding entity for optimizing paging process in a communication network. The method comprises of sending (408) the paging signal to the at least one access point in a group associated with the current priority level and determining (410) 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 (412) 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 (414) 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.
Claims17
A method comprising:
- maintaining a list of priority levels, wherein each of the priority levels is associated with a group of at least one access point and wherein maintaining the list of priority levels includes grouping a plurality of access points with one of the list of priority levels based on a weight of each of the plurality of access points;
- initializing a current priority level from the list of priority levels, wherein the current priority level is a highest priority level, further wherein the highest priority level is associated with the group of at least one access point having a highest range of weights associated with group of at least one access point, the weight of an access point being incremented when mobility is observed to the access point, the mobility including connected mode mobility and idle mode mobility;
- sending a paging signal to the at least one access point in a group associated with the current priority level;
- determining whether a page response is received from the at least one access point in the group associated with the current priority level;
- updating the group associated with the current priority level;
- and
- assigning a next priority level in the list of priority levels as the current priority level when no page response is received from the at least one access point in the group associated with the current priority level.
A method comprising:
- creating a list of priority levels, wherein each of the priority levels is associated with a group of at least one access point,
- initializing a current priority level from the list of priority levels, wherein the current priority level is a highest priority level, further wherein the highest priority level is associated with the group of at least one access point having a highest range of weights associated with group of at least one access point, a weight of an access point being incremented when mobility is observed to the access point, wherein the mobility activity includes connected mode mobility activity and idle mode mobility activity;
- selecting a group associated with the current priority level in the list for sending a paging signal;
- updating the weight of an access point in the selected group associated with the current priority level;
- and
- associating the access point with one of the list of priority levels based on the updated weight of the access point.
An apparatus comprising:
- a memory for maintaining a list of priority levels, wherein each of the priority levels is associated with a group of at least one access point;
- and
- a processor coupled to the memory and operable to determine whether a page response is received from the at least one access point in the group associated with a current priority level, wherein the current priority level is a highest priority level, further wherein the highest priority level is associated with the group of at least one access point having a highest range of weights associated with group of at least one access point, a weight of an access point being incremented when mobility is observed to the access point, the mobility including connected mode mobility and idle mode mobility, sending the paging signal to the at least one access point in the group associated with a next priority level only when no page response is received from the current priority level and modifying the weight of an access point in response to the mobility of mobile stations associated with the access point.
