Paging methods and apparatus
Improved paging methods and apparatus are described. Paging requirements for a page are determined from paging information. Paging requirements may include, e.g., transmission delay constraints, paging resource requirements, whether or not a page is to be acknowledged, quality of service information, etc. A page is generated and transmitted by the node determining the paging requirements. In other embodiments, paging requirement information is communicated in a message to a node which is responsible for paging transmission resource allocation and/or actual transmission of a page. The methods and apparatus of the present invention allow pages to be treated on a differential basis according to a page's particular requirements. Different quality of service levels can be maintained for pages with pages having a higher QoS being given resource allocation priority and/or scheduling priority over pages corresponding to lower levels of page QoS.
1 . A communications method, the method comprising:
servicing a plurality of different paging requests by allocating different amounts of a paging transmission resource to different paging requests, said paging transmission resource being one of transmission power, bandwidth, frequency, and transmission time slots; and
transmitting a page corresponding to one of said plurality of different paging requests over a wireless communication link using the amount of said paging transmission resource allocated to said one of said plurality of different paging requests.
2 . The method of claim 1 , wherein said servicing and transmitting steps are performed by a base station.
3 . The method of claim 1 , wherein said paging transmission resource is bandwidth.
4 . The method of claim 1 , wherein said paging transmission resource is frequency.
5 . The method of claim 1 , wherein said paging transmission resource is time slots.
6 . The method of claim 1 , wherein said paging transmission resource is transmission power.
7 . The method of claim 1 , wherein allocating different amounts of a paging transmission resource includes allocating a minimum fraction of paging channel capacity to a group of paging requests having a common quality of service indicator.
8 . A method of operating an access node, the method comprising:
allocating a minimum fraction of paging channel capacity to a group of paging requests having a common quality of service indicator; and
transmitting a page corresponding to one of the paging requests in said group over a wireless communication link.
9 . A method of operating an access node, the method comprising:
determining an ordering in which pages corresponding to a plurality of paging requests are transmitted based on a time constraint requirement associated with one of said plurality of paging requests; and
transmitting a page corresponding to said one of the paging requests over a wireless communications link.
10 . The method of claim 9 , wherein said time constraint requirement is a maximum latency.
11 . The method of claim 9 , wherein said step of transmitting a page includes transmitting said page corresponding to said one of the paging requests prior to transmitting a page corresponding to a previously received paging request.
